(In this universe everyone goes to U.A but it's more like a collage where everyone has to be 18+ to attend)

Chapter 1: Late Night Stroll

D-DAMN NERD!" Bakugou hissed, clutching his arm. His chest rose and fell with ragged breaths, eyes locked on the unconscious body at his feet.

"ALLLLRIIIGHT, THE WINNER IS BAKUGOU!!!!" Present Mic's voice reverberated through the training grounds, everyone stood frozen, looks of horror plastered on their faces as their eyes glared at the so called "winner". It only took a few minutes before Recovery Girl was on the scene with two nurses following in behind her, they quickly made their way over to the bloodied heroes in training.

Hero? What kind of hero beats their own classmate to a bloody pulp!? Recovery Girl thought grimly as she began checking Izuku's vitals, which weren't looking too good. She took a deep breath clearing her mind No time to be thinking like that, right now my patient needs me.

"The boy's out cold, let's get him to the infirmary." She commanded as the two nurses lifted Izuku's body onto the stretcher. She glanced to Bakugou before stating, "Whether you like it or not you will be receiving treatment too!" Bakugou glared at her, arms crossed over his chest. "Tch, fine but only because I have to not because I want to." He scoffed, as they all made their way out of the training grounds. 

The class had been training the whole day and everything was fine until Aizawa insisted that Izuku and Bakugou team up. His partner Yamada expressed his concerns from the beginning knowing the type of chaos those two caused together but Aizawa just brushed him off.

Damn it, he thought knowing that later he'd be hit with an "I told you so!" Aizawa facepalmed as he looked at the state the training grounds were in, these kids have really done it this time.

After taking a deep breath he turned to the class, still in their statue like state, "Alright everyone let's call it a day, Yamada and I have some cleaning up to do" That seemed to shake everyone out of their trance as everyone piped in at once.

"Is Izuku going to b-be ok?" Uraraka yelped with worry. "yeah, ribbit.. Bakugou really did a number on him" said Tsu solemnly "I wouldn't worry about those two, they've had a lot worse before, besides maybe the recovery will force them to rest a couple days!" Kirishima chimed in with a toothy grin. 

Everyone left one by one until it was just Aizawa and Yamada alone in the midst of what was left of the training grounds. Aizawa could feel eyes burning a hole in the back of his head. "Sigh, what is it?" He said begrudgingly knowing what was about to come. "Oh it's nothing, buuuut I told you so~" Yamada said cheekily with a shit eating grin. 

"Yeah yeah I know! Get back to cleaning." 

 

 

Bakugou's leg bounced in anticipation. The sharp smell of alcohol mixed with the faint smell of freshly washed linens filled his nose as he looked around, trying but failing to find something to distract him. His face resting into a deep scowl as he glared at the clock on the wall. Its ticking echoed through the small room, nearly driving him insane.

"Tch, this is boring."He muttered under his breath

Unable to sit still any longer, he stood and began pacing back and forth in front of the infirmary bed. Izuku lay there, unconscious, his breathing steady and soft with the occasional snore. Recovery Girl had already patched up; bruises gone, wounds healed, vitals stable. Now all Bakugou could do was wait for the damn nerd to wake up.

And Bakugou hated waiting.

Suddenly the silence was broken with a hoarse cough. "K-Kacchan..." Izuku rasped, his voice barely more than a whisper. Bakugou was by his side in an instant "Shut up nerd. I'm right here."

Even though Bakugou's words were a bit harsh, and he still had that angry look on his face, Izuku could tell he was worried about him. 

"Here drink this!" Bakugou shoved a glass of water towards him, the movement rough but precise, not a single drop spilled. Izuku tried his best as shaky hands reached for the glass, but it was no use. 

"Tch, do I have to do everything for you? Hold still." A flush fanned Bakugou's cheeks as he huffed. Then with an unusual gentleness, his hand cupped Izuku 's cheek and lifted the glass to his lips. 

Izuku's face turned a deep red as he tried not to get choked on the water but the gesture had his head swarming with thoughts. OMG! He's so close! Why is he being so nice to me? Why are his hands so war-AHHHH, No!  Stay calm Izuku, he's just helping you out! No reason to make things weird.

Izuku focused on the warm hand resting on his cheek as his body began to relax; his shoulders lowered, his teeth unclenched, and his eyes slowly fluttered shut. The only thing grounding him was the warm hand on his cheek and the cool water soothing his throat. 

Bakugou's hand remained steady as the green haired boy gulped down the water, one would assume that he'd had gone days without any with the way he was chugging. Bakugou watched attentively, noticing an unexpected wetness. Water had begun trickling out the corner of Izuku's mouth, down the glass, and over his arm. 

Stupid Deku! What kind of idiot doesn't even know how to drink water without making a mess? And why does he have to do it with that cute look on his face. Bakugou grit his teeth. He hated how Izuku could make him feel these things; soft, flustered, weak. And for that… it made him want to crush him.

Bakugou was cut off mid-thought as Izuku’s eyes suddenly locked onto his. He gazed into those forest-green orbs, admiring the way the light caught in them, glinting like dew on spring leaves. His eyes drifted lower, catching the soft pink dusting Izuku’s freckled cheeks.

His mind cleared for a moment, only to realize the glass was still pressed to Izuku’s plump, pink lips. Bakugou pulled it away, trying to play it cool, but like a moth to a flame, his eyes were drawn back to them.

In his left hand, he held the chilled glass. But in his right, his fingers still cradled the warm curve of Izuku’s cheek. His thoughts grew hazy as he found himself leaning in.

What the hell am I doing? Why am I feeling like this… like I want—like I want to kiss him?

Before he could stop himself, it was already too late. His lips met Izuku’s; soft, warm, and trembling. They fit perfectly, like puzzle pieces long overdue for connection. For a moment, everything else melted away. The noise, the fear, the anger—it all vanished. In that brief, stolen second, he felt at peace.

And then, like a moth flying too close to the fire, he felt the sting.

He pulled back, blinking, heart hammering. Izuku’s face was crimson, redder than Bakugou had ever seen it. His hand trembled in the air between them."KatsuKI!" Izuku shouted, his voice breaking.

And in that moment, Bakugou knew he’d messed up. Izuku never called him by his first name.

Bakugou was mentally conflicted trying to make sense of what just happened. What the hell is wrong with me? Why did I just do that? He felt his face heat up in embarrassment as he glanced over to Izuku. 

He held his head downward, his eyes glistened on the verge of tears. Bakugou swallowed the lump in his throat as he tried to work up the courage to apologize. "Deku, listen...I didnt mea-" but before he could finish his sentence the door burst open.

Bakugou jumped up nearly falling off the bed trying to seem inconspicuous. Recovery Girl walked in with a smile on her face, looking as dandy as a daisy. "Ah you're finally awake, how are you feeling?" She said with a big smile. 

"Ah- um I'm f-fine!" Izuku stammered out nervously, face still red. As Recovery Girl got closer she smirked to Bakugou with an all knowing look "Hmmm it seems you're running a fever, your face is rather red. Bakugou you should of came and got me sooner." A vein popped out of Bakugou's head as he snapped with frustration. "Tch, well sense you are here now I don't have to babysit anymore. I'm LEAVING!" 

And with that Bakugou stormed out slamming the door behind  him. Recovery Girl chuckled as she brought her attention back to Izuku. "Ha ha, there isn't a dull moment around that one is there Izuku? Your teachers must have their hands full." 

Izuku responded back with a nervous chuckle "Ha, yeah he can be pretty intense sometimes but he's not as bad as he seems. Believe it or not we used to be friends when we were younger but over the years we've drifted apart." Recovery looked at him, sadness in her eyes. "Well even though he did beat the tar outta you, he did just stay here by your side for the past 4 hours waiting for you to wake up, so I guess there is some good in him" 

Izuku's head snapped up in shock. "R-really? That long?" Recovery Girl nodded her head with a "Mmmhmmm, and he didn't even leave to take any breaks at all, it seems that boy has a soft spot for you." 

Izuku say speechless as Recovery Girl did one last check over his vitals. A pang of guilt washed over him as he thought back to earlier. I can't believe I smacked him across the face, he could of killed me for that. But then again if he really hated me that much why did he-? 

Izuku touched his lips reminiscing on the kiss that Bakugou had so blatantly planted on him. It was just so unexpected and so unlike him.

Izuku shook himself out of his thoughts as he watched Recovery Girl check his temperature. "Well it looks like the fevers gone, you should be good to go back to your daily activities, all we gotta do is sign some paperwork and you will be on your way." She said gleefully. 

"Th-thank you, seriously I don't know what we'd do without you!" Izuku said with enthusiasm. After that Izuku signed the papers, gathered his things, and said goodnight to recover girl before leaving the infirmary.

The halls were empty as he passed his classmates dorm rooms, If he focused hard enough he could hear some of them snoring. He lightly chuckled to himself as he quietly approached his own dorm. He turned the handle slowly as the door creaked open.

He had only been in the infirmary for less than a day but the hospital-like smell was nothing compared to the cozy scent of green apples that welcomed him Everytime he stepped inside of his room. It was like a breath of fresh air. 

He sat his backpack down and began slipping of his shoes and highschool uniform, he made his way over to his dresser and pulled out a pair of black and green checkered pajama pants along with a soft black hoodie. 

When he was done changing he flopped down on his bed and relaxed into the clean sheets. Even though he had been patched up by Recovery Girl, his muscles still ached. 

He lay there tossing and turning trying not to think back to today's events but he couldn't get them out of his head. Why? The question racked his brain trying to make sense. Why had Kacchan been so nice after beating the daylights out of me during training? Why was he concerned for me when he's been bullying me for years? And why did he kiss me?

Izuku blinked, as if shaking off a daydream, but the memory clung to him like static. The warmth of Bakugou’s lips, the confusion in his eyes after he had smacked him, it haunted him. He glanced at the clock on his nightstand 11:37 P.M it read in bright red letters. He sighed as he heaved his achy body up and put his shoes back on.

He quietly crept out of his room before making his way back down the hall he had just came from about 30 minutes prior. He walked down the multiple flights of stairs before heading out the back door of the school, inhaling the crisp night air. 

Whenever Izuku was overwhelmed, a late night stroll always helped him clear his head. He walked down the sidewalk keeping his head low trying not to draw too much attention. He knew walking alone a night wasn't always the best idea, especially with the villain attacks that have been on the rise recently.

But he just couldn't help himself, he needed this, needed a moment to relax after all the chaos.  He kept walking until he was in a small neighborhood about a mile from the school. He watched as a couple of cars went by, mind relaxed but not completely unguarded. 

Everything was quite peaceful until a bit of ruckus caught his attention. He looked over to an alleyway where he could see a shadowy figure and what looked to be a woman that had been cornered. Izuku 's heart leaped for a moment as he watched quietly.

"Unhand me!" The woman shouted as she fought against the figure. What sounded like a man's voice echoed down the alley. "Awww come on baby, I'm just here to have a good time~" A shiver went down Izuku 's spine as he tried to find a good opening to act.

He started walking towards them, their voices getting louder the closer he approached. "I said leave me alone!" The woman shouted as she threw a punch but the man caught her arm. "Not going to happen baby!" He said with a creepy grin. 

Izuku started to activate one for all, body glowing in green electric-like tendrils as he began to charge. But just as he was about to attack he stopped mid step.

He looked in horror as the woman grabbed the man's face and a wide grin pulled at her cheeks "Ha ha, I tried to warn you but no, you thought you saw an opportunity to take advantage of a helpless woman and you took it, well now you are the one who is going to be helpless" she said as her jaw opened up wide. 

Izuku watched in horror as her sharp, vampire-like teeth sunk deeply into the man's neck, blood gushing down his torso. Wet sucking noises echoed as the man shouted out in pain. Izuku tried to move but he was frozen in shock. 

Come on, you have to move, she's going to see you! His mind screamed but it was too late. 

The woman gave one last slurp before tossing the man's body to the ground, blood running down her chin and staining her clothes. Her glowing red eyes locked on Izuku 's as she let out a chuckle.

"Hu Hu! What do we have here? I think one of U.A's lambs has gotten lost, what are you doing out here all by yourself~" she cooed. Izuku tried to settle his panic as the woman got closer.

"Come on boy, it's rude to ignore someone when they are talking to you." She said sternly, at this point the lady was towering over Izuku while he sat on the ground trembling. He looked up at her, swallowing the lump in his throat before speaking. "I-I'm out on a late n-night walk and I-I thought you were I-in trouble." He stammered out. 

Her shrill laugh startled him as she bent down to his eye level. "Hu Hu! Awww that's so very sweet and stupid of you. Hmmm, what to do with you now though? I know...you are pretty cute, I think I'm gonna keep you~" Before Izuku could even figure out what that was supposed to mean, the woman had yanked him forward and sunk her teeth into him. 

White hot pain flashed through his shoulder as he is yelled out . He tried so hard to focus. Tried to stay conscious, but his vision started to go black and spotty. "no, some...one..anyone" He said weakly 

Just as everything faded to black he felt the weight of the woman leave his body and faintly heard yelling. He could feel rustling around him as movement reverberated through the cold ground he was laying on. He fought to open his eyes, red orbs locking on his. He flailed his arms panicking thinking it was the woman. "N-no, st-stay back" he tried to yell but his voice was just above a whisper.

"Shut it nerd, it's me, you're ok now." The voice soothed him instantly as he was picked up. He nestled into the warm chest of his childhood friend before exhaustion overcame him.

"Deku, hey stay with me!" Bakugou said as he carried Izuku in his arms bridal style. He looked down at his face that was drained of color. Shit! He thought as he noticed the entire side of his neck was drenched in blood. 

He gripped him tightly as he ran back to the school full speed.

Chapter 2: Thirst

Bakugou stomped down the hallway as he made his way back to his dorm for the night, cheeks flushed as his fists clenched tightly. Stupid Deku! Stupid Recovery Girl! Stupid School! He grimaced, his classmates looked at him with worry as he passed the common room, whispers bugged his red tipped ears.

He scoffed as he finally made it to his room, slamming his door on the way in. He let out a deep breath, collecting his thoughts as he looked at the comfy bed calling his name.

He flung off his shoes and flopped down on his bed, not caring that he was still in his school uniform. He tried to close his tired eyes and relax into slumber but he couldn't calm the roaring ocean in the back of his mind. So much had happened that day; Training, infirmary, the...kiss and also the slap that came right after.

Bakugou hissed, nausea churned his stomach. He felt like throwing up. This wasn't like him, he wasn't the type to get so worked up over something so trivial, I mean at the end of the day it was nothing more than a meaningless kiss, right?

Kiss... the word buzzed in his head like an annoying mosquito that wouldn't die . Bakugou knew that the kiss was anything but meaningless. He knew it the moment the warmth of those plump lips had settled the roaring waves of his mind, knew it when they had fit together so perfectly, and yet now that it was over it had left him with nothing but anger, guilt, and confusion.

Thinking about it gave him an anxiety he had never experienced before. Damn nerd! I mean why does he have to be so annoyingly cute in the first place? Seducing me with those stupid green eyes and cute sun-kissed freckled cheeks AHHHH... shut up! Shut up! Bakugou fisted handfuls of hair in anger trying to get the greenette out of his mind but it was no use. 

He was startled from his thoughts as he heard shuffling in the room next over from his. It was Deku's room of course, they had unluckily been placed right next to each other.

Bakugou had yelled at Izuku a couple of times for his late night super hero babble and the All Might videos he'd like to blast at 11:30 at night. But tonight the nerd seemed to be stumbling about causing a bunch of racket.

With an irritated grumble, Bakugou turned over and kicked the wall next to him. "Oi! Would you quiet down over there!" And usually Bakugou would be met with an "Ah- Uh sorry Kacchan." or just an occasional "s-sorry" but tonight all he was met with was silence. 

He sat there for a minute contemplating, he knew he had already worried himself enough with the nerd but he couldn't help the voice in the back of his head telling him something was wrong. 

With an annoyed huff he hoisted himself up and walked back over to his door, and put his shoes back on. He stepped outside into the hallway and looked over to Izuku 's room, his door was ajar.

Curiously, he walked over and peeked his head in, empty. "Just fucking great!" He spat, already dreading the fact that now he had to hunt the nerd down. 

 

He swiftly walked down the hallway, almost running as his eyes darted around searching for any trace of Izuku, but all he saw was Kirishima standing there looking at him with worried eyes. 

"Hey Bakugou, what are you doing up so late?" Kirishima questioned. Bakugou stopped in his tracks, sighing, “Look, usually I don’t get involved with these extras but...I'm looking for Deku." 

Kirishima's eyes softened, taken aback by the blonde's sudden honesty. Without hesitation he pointed down the hallway. "He actually just passed me a couple minutes ago, it appeared he was heading towards the back of the scho-" Before he could even finish his sentence, Bakugou ran like a bat out of hell. 

Kirishima stood there stunned and then shook his head with a smirk. Guess Izuku isn't just an extra to him after all. 

 

Bakugou panted as he ran down the multiple flights of stairs, feet stomping like an angry bull. He made his way to the backdoor of the school, stepping outside. He stopped to catch his breath inviting the cool night air to ease his burning lungs. He looked around, still no sign of the nerd. Damn where could he be!?

His mind wandered as he remembered the late night strolls him and Izuku took when they were kids. He remembered small hands clutching his sleeve, Deku rambling about hero stats while Bakugou kept watch for danger. Always behind him. Always trusting. But things are different now, Bakugou didn't have time to babysit some weakling, he had a job to do and that was to surpass all might. Yet here he was looking around for him like a lost puppy. 

Bakugou shook the memory from his head focusing, Of course! He's probably walking around the town right outside of Musutafu. Sparks crackled beneath his feet as he blasted forward, black marking the sidewalk as his heart hammered in his chest. 

The sound echoed through the woods around him, his eyes narrowed as the tiny town appeared in the distance. 

Before long Bakugou was passing picket fences and mailboxes. His breathe steadied as he began to jog, he could hear dogs barking in the distance, the sound of a couple cars passing him every now and then, and also the sound of a young couple arguing from inside their home. 

His eyes squinted against the street lights, focusing as he searched down street corners and parking lots, but still no sign of the nerd. His patience dwindled with every passing minute until a shrill scream alerted him. He immediately knew it was Deku's

Shit! He gritted is teeth, the sound of the concrete beneath him hissed and cracked as he leaped in the direction of the sound. Adrenaline pumped in his veins as the scream grew louder and louder.

Bakugou's concern grew as he got closer until suddenly the screaming stopped, and eerie silence sent a chill down his spine and he looked around frantically. 

His heart pounded in his ears, he knew Izuku was close but couldn't pinpoint the exact location. He took a deep breath, taking in his surroundings; flickering street lights, some old bikes chained up, a convient store, an ally way, blood.

Bakugou dashed towards the alleyway eyes narrowing in as he could see a lady hovering over a body, a puddle of blood pooling beneath it. 

Bakugou raised his fist, charging "GET THE HELL AWAY FROM HIM!" His fist connected to the woman's jaw, teeth cracking as her body flew across the alley, bouncing a few times before skidding to a stop.

Bakugou dropped to his knees beside the body. Izuku was pale as a corpse. Two puncture wounds bruised purple, still weeping blood down his neck soaking his hoodie. 

Bakugou’s heart stopped.

Izuku’s eyes fluttered open, barely conscious. His arms flailed weakly. “N-no… st-stay back,” he whispered, his voice shredded and soft.

“Shut it nerd. It’s me, you’re okay now,” Bakugou said, voice trembling as he scooped Izuku up in his arms.

The greenette slumped against his chest, barely breathing. "Deku, hey! Stay with me!" 

Bakugou gripped Izuku tightly as he dashed to the school frantically.

 

Izuku felt numb, exhaustion pulling him into an inky abyss. He tried to open his eyes but his lids felt like they weighed tons. A voice in the back of his head echoed out, stirring his conscience. 

"D....u" Izuku tried to concentrate but his head was killing him. "De...ku" Izuku felt his eyes twitch as a low voice flooded into his ears. "Deku." 

Izuku's eyes flicked open, blinking a couple times as his vision cleared. Bakugou sat at the end of his bed looking at him with worried eyes that were focused on him. "How do you feel?" He questioned.

How do I feel? He thought as he focused on the sensations around him. His body although achy seemed to have this tingly burning sensation that almost made his skin crawl. The smell of alcohol burned his sinuses, the sound of the beeping machine tickled his ears, and the light caused his eyes to burn. 

It seemed like his senses were enhanced, making him overstimulated and bothered. He tried to speak, the feeling of hot knives down his throat. He began coughing "Wa...ter" 

Bakugou nodded in understanding as he made his way to Izuku's side, a glass of water in his hand. A sense of deja vu prickled his brain as Bakugou raised the glass to his lips. "Just like last time, kay nerd?" Bakugou's gruff voice reassured softly as Izuku tried to sit his lips around the glass comfortably but something kept getting in the way. 

He felt a few drops run down, stinging but soothing the dryness in his throat. But it wasn't enough. 

Izuku grew impatient as he felt his teeth knock against the glass, the thirst becoming unbearable as he suddenly lost control of his body. His teeth clamped down shattering it, sending water and shards tumbling to the ground as Bakugou jumped back. 

"Deku! What the fuck?" 

Izuku's face heated up in embarrassment as he tried to process what just happened but something snapped him out of his thoughts. 

Izuku looked up at Bakugou, scarlet dripping from the palm of his hand. Bakugou winced as he tried to play it off.

"Ah, it's ok Deku don't worry about it, you didn't mean t-mphh!" Bakugou grunts as his back is slammed against the infirmary floor, the wind knocked clean out of his lungs. His brain barely registers what just happened before Deku is on top of him, knees straddling his waist, face pale and eyes glowing crimson in the low infirmary light.

“Deku?! The hell are you doing!?”

Izuku’s breath is ragged, mouth hanging open, fangs visible, actual fangs. His whole body trembles like he's fighting something inside him. His hands shake where they clutch Bakugou’s shoulders, fingers twitching.

“I-I’m sorry.” Izuku chokes out, “I didn’t mean to, I just-I saw the blood and something snapped and I-”

Bakugou’s eyes dart down to his bleeding hand. The scent of iron hangs thick in the air. Shit!

He grabs Izuku by the neck of his hospital gown and tries to shove him off, but the strength Izuku shows is not human anymore. Not the scrawny, muttering nerd he's used to throwing around. This is something new. Something dangerous.

"Deku, get a grip!" Bakugou growls.

Izuku shudders, jaw clenched. “I can’t-I can’t stop thinking about it! I can smell it...I can hear your heartbeat.”

Bakugou freezes.

There’s a long pause.

“…You can hear my heartbeat?”

Izuku’s head drops forward, forehead pressing to Bakugou’s collarbone. “Please... I don’t want to hurt you. You need to go.” But Bakugou doesn’t move. His hand stays on Izuku’s back, and his voice lowers just enough to be sincere.

“Like hell I’m leaving you like this. Here, take my hand." 

Bakugou raises his bloody palm up to Izuku's pale face, light pink dusting his freckled cheeks. Izuku grabs his wrist desperately with shaky hands as he slowly brings it to his mouth.

Bakugou braces himself for the sharp pain of a bite but is met with Izuku's slimy hot tongue. And now it's his turn to blush.

Bakugou covers his face with his other hand as he tried to block out the moans and slurps coming from Izuku as he licked and sucked greedily. "Mhmmm Kacchan, you're blood is so-so good!" 

The sensation wasn't bad, in fact he started to feel a soothing warmth envelope the aching wound, leaving it with a slight tingling. 

Bakugou tried to focus on anything but the greenette, but it was kinda difficult considering he was straddling his lap, almost grinding against him. Shit if he keeps this up things are going to get really awkward.

"Damn it! Could you maybe do that more quietly? And stop squirming so much!" Bakugou barked out, startling Izuku out of his haze. "Oh, sorry Kacchan, I think I'm done. Look your hand is all healed now!" He said enthusiastically as he hopped up. 

Bakugou took Izuku's hand as he hoisted him up from off the floor with an inhuman strength. Bakugou blushed as they were now standing face to face with each other.

He scratched the back of his neck as he scoffed "For someone that looked like complete utter shit just a few minutes ago you seem a lot better now." Izuku laughed nervously trying to brush off the awkward tension in the air.

"Ha, yeah! That blood really revitalized me, thanks Kacchan. Anyways something is definitely off. I mean craving blood like that definitely isn't normal." 

Bakugou could feel a vein pop out of his head as he clenched his teeth. "Yeah you think dumbass!? Anyways let's go get recovery girl because you're acting even more like a freak than usual." 

"Kacchan, so mean" Izuku pouted as they walked out of the infirmary door down to Recovery Girl's office. 

 

"Knock Knock" Bakugou said as him and Izuku entered in.  Recovery Girl was tidying up her medical supplies when she turned, startled by the sound.

Her eyes widened at the sight before her.

“Izuku Midoriya?! What on earth are you doing on your feet?! You were on death’s doorstep just hours ago!” she exclaimed, rushing over.

Izuku rubbed the back of his neck sheepishly. “Heh... yeah, I’m... feeling a lot better, actually.”

Bakugou scoffed, dragging his feet behind him, arms crossed. “Yeah, he looks better all right because he drank my damn blood.”

Recovery Girl blinked. “Excuse me?”

“Oh, and that’s not even the freakiest part,” Bakugou snapped, voice rising. “He's got fangs now! Glowing red eyes! Threw me across the room with one arm like I was a pillow and pinned me. So yeah, real picture of health.”

Izuku flinched. “Kacchan! I didn’t mean to! I-I lost control... It’s like my body wasn’t mine. All my senses were heightened and I could hear Bakugou''s heartbeat.  I was so thirsty I couldn’t think straight.” His voice cracked, and he looked down at his hands. “I didn’t want to hurt anyone. But I couldn’t stop.”

Recovery Girl placed a hand on her chin, eyes narrowing thoughtfully. “Hmm... I was afraid of this.”

Bakugou tensed. “Afraid of what? You knew something?”

She nodded slowly. “The symptoms all line up. Enhanced senses. Bloodlust. Loss of bodily autonomy. The attacker must have been Lady Noctra.”

Izuku’s breath caught. “You know who she is?”

“Only from reports,” Recovery Girl said grimly. “She’s a dangerous villain, presumed dead for years, but sightings have popped up recently. Her Quirk is a terrifying combination of shapeshifting, vampirism, and the ability to create ‘minions’, humanoid puppets she controls after biting them. Usually, once bitten, the transformation is irreversible.”

Bakugou’s jaw clenched. “So what? You’re saying Deku’s one of her blood zombies now?!”

“No,” Recovery Girl shook her head. “That’s just it. You interrupted the process. Stopped the transformation before she could finish.”

Bakugou scoffed again, louder this time. “Great. So we’ve got half a vampire nerd running around with super senses and a taste for blood.”

Izuku groaned. “Kacchan—”

“No, shut up. I had her right there, and if I’d just gone a little harder!”

Recovery Girl frowned. “Easy, young man. I know you’re frustrated, but your concern should be with Midoriya’s condition. Lady Noctra escaping is unfortunate, yes, but Izuku needs stability right now.”

Izuku’s brows furrowed. “So... what happens to me now?”

She looked at him kindly, but her tone was firm. “We monitor you. Closely. If she didn’t complete the transformation, you may still have time before any permanent changes take root. You may be able to fight the vampiric influence... or it could worsen. We just don’t know, I will talk to Nezu to see about getting you some blood bags and maybe some volunteers to help deter your bloodlust." 

The thought of drinking blood everyday disturbed Izuku but he couldn't deny it also made his mouth water. 

Recovery Girl gave them both a long look, clearly weighing whether to say more. Eventually, she let out a slow sigh. “That’s all for now. Midoriya, Bakugou, you’re dismissed. Go get some rest, and don’t do anything... reckless.”

Izuku stood up slowly, rubbing the back of his neck. “Right. Thank you…”

Bakugou muttered something under his breath that sounded like “Yeah whatever,” before shoving his hands into his pockets and heading out the door.

The two walked in silence down the hallway, their footsteps echoing in the quiet of the night. The tension between them hung heavy, charged with all the words left unsaid in Recovery Girl’s office.

Finally, Bakugou couldn’t take it anymore. “You’re such a dumbass, you know that?”

Izuku blinked, startled. “Huh?”

“You don’t just go off on your own like that late at night!” Bakugou snapped, shooting him a glare. “You’re lucky I showed up when I did. If I hadn’t-if that freak had-you’d be a corpse right now!”

“I didn’t plan on getting attacked,” Izuku snapped back, voice sharper than usual. “I just needed air! My head was a mess. What? I’m not even allowed to walk anymore?”

“That’s not the point, damn it!” Bakugou growled. “I’m saying maybe think for once before running off like a helpless idiot.”

Izuku stopped walking stopping in front of their dorm rooms. “Why do you even care?!” Bakugou turned, eyes narrowed. “What?”

“Why now?” Izuku demanded, fists clenched. “After all these years of you bullying me, tearing me down every chance you got! Why are you suddenly acting like you give a damn whether I live or die?”

Bakugou looked like he’d been slapped. He averted his eyes, jaw clenched.

“I-It’s not that simple…” he muttered.

“Oh, come on,” Izuku pressed. “What is it then? Why are you being like this?”

Bakugou spun around, face flushed. “Because I couldn’t stand it, alright?! I couldn’t stand the way you made me feel!” Izuku blinked. “What...?”

Bakugou threw his arms out in frustration. “These stupid feelings. I don’t know what they are. I just know I hate them! Worrying about you. Feeling anxious every time you’re gone too long. Feeling guilty for what I did back then. Feeling like-like shit when I saw you bleeding out in that alley.”

He took a step back, voice cracking just barely. “I even went out to look for your dumbass.”

The hallway went quiet. Izuku’s mouth opened like he wanted to say something, but nothing came out. Bakugou stared at him, chest rising and falling fast. “So just... shut up already!”

And before Izuku could speak, Bakugou spun on his heel, stormed into his dorm, and slammed the door behind him with a resounding BANG.

Izuku stood frozen, the echo of the slammed door ringing louder than his heartbeat. His cheeks burned. His chest ached. He didn’t know what stunned him more; Bakugou’s words, or the fact that they made him feel something.

“What... just happened?” he whispered. He blinked down at his trembling hands, then up at Bakugou’s door. His pulse pounded in his ears. And for once, Izuku Midoriya had absolutely no idea what to do next. So he turned around, opened his door and went the hell to sleep. 

Chapter 3: Awkward Situations and Jealousy

An old mansion overgrown with wildlife sat deeply in a foggy forest, shadows lurking. Velvet curtains fluttered in the moonlight that poured through the windows, casting eerie patterns along the polished marble floor. The scent of old blood clung to the walls like perfume; sweet and stale.

Lady Noctra sat draped across a throne-like chair in the center of the room, her sharp red nails tapping against the armrest rhythmically. Her long black hair spilled over the shoulders like ink, blending with the darkness. Her once pristine lips curled into a snarl as she cradled her jaw, still sore from the blonde brat’s punch.

“Damn him,” she hissed, voice silken and full of venom. “Damn that boy… Katsuki Bakugou.”

She shifted, teeth baring as pain shot through her gums again. “He broke one of my fangs,” she muttered bitterly, eyes glowing crimson in the dark. “Do you have any idea how long it takes to regrow these?”

She cast a glance at the fireplace in front of her, where a few pale-skinned, shadow-eyed minions sat huddled around a flickering flame. They twitched at her every movement, loyal... but restless.

“And that Midoriya brat,” she sighed, slumping back in her seat "So much potential. His energy, his blood, it was perfect. If only I had more time, he would’ve made such a beautiful monster…”

“Lady Noctra,” one rasped of the minions rasped, licking cracked lips, “We’re starving.”

“We haven't fed in days,” another chimed in, voice barely more than a breath. “Please... we need something.” Noctra’s eyes narrowed, and then, slowly, her lips curled into a cruel smile. “Is that so?”

She stood with slow, eerie grace, hair lengthening around her like a cloak. With a click of her tongue, she extended one delicate, pale wrist.

“Come then, little pets,” she purred. “Take what you need.” The minions hesitated for a beat, then surged forward like animals, teeth sinking into her offered flesh. She didn’t flinch. If anything, her smile only widened.

“You’ll have your fill,” she whispered, staring out the tall, cracked window where the moon hung full and cold above the forest. “Because we’ll need our strength. Next time, I won’t fail. Midoriya will be mine…”Her eyes gleamed with deadly promise.

“…And Bakugou will die screaming.”

 

Back at U.A., Recovery Girl stood by her desk, paperwork neatly stacked in front of her, though her expression betrayed the tension behind her usual composure. Her gloved fingers were steepled beneath her chin as she waited.

A soft knock came at the door before it creaked open, revealing the small, fur covered figure, Principal Nezu. He walked in calmly, a steaming cup of tea in his paw.

“Good morning,” he greeted with a chipper tone, though there was an unusual weight behind his gaze. “You said it was urgent?”

“Yes.” Recovery Girl gave a firm nod. “It’s about Midoriya.” Nezu’s ears twitched. “Ah. I assumed as much. I heard the incident was rather intense.”

“That’s putting it lightly,” she replied, sighing as she leaned back slightly. “His senses have been altered. Bloodlust. Fangs. Inhuman strength. The transformation didn’t complete, but whatever that creature, Lady Noctra, did to him, it’s progressing.”

Nezu set the cup down and folded his paws on the desk. “So what’s the prognosis?”

“We don’t know,” she admitted. “Which is why I’m requesting we start blood bag support immediately. It seems to be the only way to manage his cravings. If he goes without… I fear he could lose control again. And next time, there might not be anyone to stop him.”

Nezu hummed thoughtfully. “We can source medical-grade blood bags easily enough. I’ll authorize it.”

She hesitated, then added, “And… I’d like permission to discreetly ask for donor volunteers among staff. Having live donors might allow us to study how his body reacts to fresh versus stored blood.”

Nezu’s expression grew serious. “That’s… ethically complicated.” His tail flicked behind him in slow contemplation. “But I understand the necessity.”

He took a sip of tea. “I won’t allow direct feeding from live people. Not yet. But I will approve a volunteer based system where we draw blood from volunteers and let Midoriya drink those bags immediately."

Recovery Girl nodded in agreement. “That’s reasonable.”

“And we’ll need to monitor his mental state. Vampirism, especially if it's fused with a Quirk, can affect impulse control. The last thing we need is a power hungry, blood-starved student in a building full of quirks.”

“I was hoping you’d say that,” she replied. “We need staff awareness. I suggest we hold a quick faculty meeting.” Nezu stood, collecting his cup again. “I’ll call one immediately. And Recovery Girl…”

She looked up. “Yes?”

He gave her a small but sincere smile. “Thank you for being cautious. It’s not just his powers we’re protecting. It’s his humanity.”

 

In the staff conference room, a heavy silence settled as U.A.'s top faculty members took their seats. Aizawa stood in his usual slouch against the wall, arms crossed, while Present Mic sat forward, unusually quiet. Cementoss, Midnight, Ectoplasm, and a few others joined the table. Nezu sat at the head, fingers interlaced in front of him.

Recovery Girl stood beside him, clearing her throat.

“Thank you all for coming on short notice,” she began, scanning the room. “As some of you may have heard, there was a serious incident involving Midoriya Izuku last night.”

Aizawa narrowed his eyes. “Serious as in?”

“Serious as in he was attacked by a known villain, Lady Noctra,” Recovery Girl replied. “And partially transformed.”

Gasps went around the table. Aizawa's jaw tightened. “Transformed into what exactly?”

Nezu answered. “A vampiric hybrid. Her Quirk enables her to bite and ‘convert’ others into subservient minions, using a combination of bodily mutation and blood manipulation. We believe Midoriya’s transformation was interrupted before it could be finalized.”

“Interrupted?” Present Mic asked. “By who?”

“Bakugou,” Nezu said with a smile, “rather explosively, I might add. His timely intervention may have prevented a full takeover of Midoriya’s mind and body.”

“That doesn’t mean the threat is over,” Recovery Girl continued. “Midoriya is showing heightened senses, thirst for blood, and moments of instability. But he is lucid. He knows something is wrong, and he wants help.”

Cementoss raised a hand. “So... what do we do?”

Nezu straightened. “First, Recovery Girl will be given permission to store blood bags for him. I’ve also agreed to allow carefully selected staff volunteers to donate fresh blood, never direct feeding.”

Some murmurs and uneasy glances rippled through the staff, but no one objected.

“We also need to be increasing surveillance,” Aizawa added. “I’ll be monitoring him closely during training and daily activities. I want at least one teacher aware of his location at all times. Until we know how this... partial transformation plays out, we can’t take chances.”

Midnight tapped her chin thoughtfully. “Does he pose a threat to the other students?”

“Not yet,” Nezu said. “But his cravings could intensify. He already lost control once, though Bakugou managed to contain it without injury.”

“Barely,” Recovery Girl muttered under her breath.

“We’ll evaluate as we go,” Aizawa concluded. “If he becomes unstable, I’ll take responsibility for subduing him. But until then, we give him support. He’s still one of our own.”

A solemn silence passed through the room, and heads nodded in agreement. Nezu gave a small smile. “Very well. That will be all for now. You are dismissed. And thank you.”

 

Darkness curled at the edges of his vision like smoke, but Izuku felt warm. Too warm.

He stood in the center of an unfamiliar room, lit only by the glow of moonlight seeping through gauzy curtains. The air was thick; humid, fragrant, almost intoxicating. His body felt light, buzzing with sensation, and yet heavy with desire. He could hear it again… that sound. That heartbeat. His heartbeat.

Kacchan…

And then he was there. Bakugou stood in front of him, scowling like always, but his expression was softer somehow, confused and vulnerable. His hand was bleeding again—just like before. Deep red trickled from a split in his palm, shining in the pale light like rubies.

Izuku licked his lips.

“Go on then, Deku,” Bakugou said, his voice low and husky, breath curling like smoke. “Isn’t this what you want?”

Izuku’s breath hitched. “I… I can’t…”

“Yes you can,” Bakugou stepped closer. “You want to.”

The tension crackled in the space between them. Izuku felt it in his fangs, pressing against his lower lip as the scent of Bakugou’s blood hit him like a wave. He wanted to resist, but his body didn’t listen. His fingers curled into Bakugou’s shirt as he pushed him against the wall.

“Shit…” Bakugou’s whisper was somewhere between a curse and a dare. “You gonna bite me or what?” A smirk painted on his lips.

Izuku shivered, heart hammering. His lips ghosted over the skin of Bakugou’s throat, warm and alive beneath him. His fangs grazed it gently as Bakugou’s chest rose and fell beneath his hands.

“I’m sorry,” Izuku whispered, voice trembling.

Then he bit.

Bakugou gasped, half pain, half pleasure and Izuku drank. The blood was hot and rich, sliding down his throat like fire and honey. He groaned against Bakugou’s skin, clutching him closer, feeling the power thrum through his veins.

“Kacchan…” he moaned, mouth still on his

neck, “Y-you taste so good~”

 

“Ah-!!”

Izuku shot upright in bed, drenched in sweat, chest heaving. His sheets tangled around him like vines, clinging to his legs and torso. His mouth was dry. His throat burned.

His hands were shaking.

“What the hell was that?” He panted, pressing a trembling hand to his chest. His heart felt like it was trying to break out of his ribcage. His lips tingled. His tongue ran across sharp canines. Still there.

He gulped, trying to breathe through the unbearable hunger clawing at his stomach. His senses were on fire; the faint rustle of leaves outside, the distant hum of vending machines down the hall, even the smell of faint blood lingering under his nails from last night. He swore he could still smell Bakugou.

His face flushed violently. “I dreamt about… drinking his blood,” he whispered to himself, mortified. “Oh my god.”

He buried his face in his hands, groaning. “What is wrong with me?!”

Another cramp twisted through his gut, this one sharper. He bit back a curse. “Ugh… I-I need blood. Bad…”

And worst of all, part of him still wanted his blood.

 

The hallway was quiet, bathed in the soft golden hue of early morning light slipping through the high windows. Izuku clutched his arms tightly across his chest as he hurried down the corridor toward Recovery Girl’s office.

His clothes were disheveled; Tie untied, shoes unlaced, shirt buttoned up crookedly on the wrong buttons. And he nearly ran down the hallway, looking like a madman.

His mouth was dry, fangs throbbing with every heartbeat that echoed through the building. His body felt like it was running on fumes. He just needed to make it to Recovery Girl.

“Oi, Deku!"

Izuku froze, dread creeping up his spine. Bakugou stood a few feet ahead, arms crossed and eyes sharp. His usual scowl was softened by concern, though he’d never admit it. “You look like hell.”

Izuku ducked his head. “I’m fine. Just… on my way to see Recovery Girl.” Bakugou took one step closer. “You don’t look fine.”

“I said I’m fine!” Izuku snapped, his voice a little too sharp, a little too wild. He flinched immediately, backing away. “Sorry, I just- I really need to get to her. I’m… not doing great.”

Bakugou’s eyes narrowed, watching the twitch in Izuku’s fingers, the faint glow in his eyes, the way his tongue kept brushing his fangs like he was holding something back.

“You’re starving,” he muttered.

Izuku’s silence was answer enough.

“Then take it,” Bakugou said, holding out his hand like it was the most casual thing in the world. Izuku stared at it like it might burn him.

“No,” he said quietly. “I can’t. I shouldn’t. Recovery Girl said-”

“Fuck what she said,” Bakugou growled, stepping closer, voice low and rough. “You’re literally shaking. Just take a little. I can handle it.”

Izuku’s eyes flicked to his hand, lips trembling. “Kacchan… I’m trying to stop. If I keep drinking from you, I’ll rely on you. I don’t want that.”

Bakugou leaned in, voice dropping even lower. “And what if I don’t care?” Izuku’s breath caught.

Bakugou grabbed him gently by the sleeve and pulled him toward the nearest stairwell. "There's no cameras that point over here. No one's around,” Bakugou muttered. “Just do it.”

Izuku stared at the offered wrist again, breathing hard. The scent was there; strong, tempting, delicious. His hands clenched into fists as he backed against the wall, trembling. “I… I can’t.”

“You can,” Bakugou said, stepping closer until they were inches apart. “You need to.”

And just as Izuku’s eyes flashed crimson and his fangs bared.

“Oh! Izuku! There you are!”

Both boys froze like guilty cats. Recovery Girl stepped closer holding a chilled silver pouch in one hand, a smile on her face that didn’t quite reach her eyes.

“Just in time,” she said cheerily. “I brought you a blood bag. Why don’t you go ahead and take it while I have a quick word with Bakugou?”

Izuku’s face flamed in embarrassment as he practically snatched the bag from her hand. “Y-Yes ma’am!” bolting out of the stairwell. 

Recovery Girl turned her gaze on Bakugou, her expression calm but firm. “You care about him,” she said gently. “That’s obvious. But you need to stop letting him feed from you.”

Bakugou scoffed, looking away. “It’s not a big deal.”

“It is,” she said. “He’s unstable, and every time he drinks from you, it creates a stronger emotional dependency. You're enabling something that might not be safe. Not for him, and not for you.”

Bakugou tensed, teeth clenching.

“I understand your instincts are to protect him. But if you really want to help, you’ll guide him toward control. Blood bags. Routine. Safety. Not stolen moments in stairwells.”

Recovery Girl reached out and patted his arm. “You’re not alone in this, Bakugou. We’ll keep him safe. But you have to do your part too.”

Bakugou let out a slow breath, fists loosening. “Yeah... okay.” He said as he made his way down the hall towards the school locker room.

 

Bakugou stepped into the locker room, steam already in the air from the running showers. The distant sound of water hitting tile echoed off the walls, mingling with the sharp squeak of his locker door as he yanked it open. He grabbed a towel, shampoo, conditioner, and body wash, movements jerky and full of pent up irritation.

"Hey, Kats! What’s up, man?" Kirishima’s voice rang out behind him, casual and friendly as always.

Bakugou let out a heavy, exhausted sigh before turning to face him. “You have no fucking idea.”

Kirishima’s grin faded slightly as he took in the deep shadows under Bakugou’s eyes and the tense way he stood. “Dude… not to be dramatic or anything, but you seriously look like hell.”

Bakugou scoffed and looked away, slamming his locker shut harder than necessary. “Tch, yeah no shit. It’s all that damn Deku’s fault. Idiot decided to sneak out last night, got himself into some freak show alleyway vampire crap, and I had to clean up the mess.”

“Ohhh! So that’s why you were tearing through the halls last night,” Kirishima said, his smile returning, gentler this time. “Damn, Kats. That was actually super manly of you, not gonna lie.”

Bakugou froze. His shoulder tensed, and a faint blush crept up his neck. “What?! I-whatever! Don’t make it weird! I just-he could’ve died, alright?! I didn’t do it for some heroic bullshit.”

Kirishima raised an eyebrow but didn’t push. “Sure, sure. Just sayin’… you don’t usually go hunting down classmates unless they matter to you.”

Bakugou glared at him. “Drop it.”

He turned on his heel and stomped toward the showers, muttering curses under his breath.

Kirishima watched him go with a thoughtful look, then shook his head, chuckling. “Man… you’re not fooling anyone, bro.”

 

Izuku sat cross-legged on his bed, clutching the silver blood bag like it might slip through his fingers if he wasn’t careful. The thought of drinking it made his stomach twist.

He closed his eyes, bracing himself as he punctured the corner with his fangs and let the blood flow onto his tongue.

It wasn’t like Bakugou’s. It wasn’t warm, or pulsing with life, or laced with the maddening heat that had flooded his senses the night before. This was sterile. Cold. Bland. Like drinking cold soup from a vending machine.

But it helped. The throb behind his eyes dulled, his heart stopped hammering, and the gnawing ache in his gut quieted, at least for now.

A knock came at his door.

Still holding the bag to his lips, Izuku groaned. “Ugh… Kacchan, if that’s you, I’m not drinking from you again, okay? Recovery Girl already scolded you, and I don’t wanna be responsible for you getting yelled at again. You can come in, though.”

The door creaked open.

“Uh… not Bakugou.”

Izuku nearly choked.

He yanked the blood bag away from his mouth, crimson dripping down his chin as he scrambled to hide it.

“K-Kirishima?!”

The redhead stood in the doorway, frozen with one foot inside, eyes wide, not in fear, but in surprise.

Izuku’s face turned the color of a tomato. “I-I thought you were Kacchan-wait, I mean-uh-I can explain!”

Kirishima blinked, then grinned. “So the rumors were true.”

“Huh…?” Izuku blinked, still red-faced.

“That you’ve been, you know… turned. Partially,” He said, stepping inside and closing the door behind him. “Dude, that’s pretty cool though. You’ve got powers. New ones. I mean, sure, drinking blood is a little freaky, but hey! You’ve got sharp teeth now. Like mine!” He bared his own pointed grin, tapping one of his fang-like incisors. “We’re tooth bros.”

Izuku blinked at him, completely baffled. “You’re… not weirded out?”

Kirishima sat on the edge of the bed, propping his chin on his hand. “Nah. Look, I’ve seen people with quirks way freakier than yours. And yours isn’t even a quirk, it’s more like a condition, right? So that just makes you unique.”

Izuku hesitated. “…I almost hurt Kacchan last night. I lost control. He offered his blood and I- I can't stop thinking about it”

Kirishima’s face softened. “And yet you're here drinking from a bag like a responsible half-vampire guy.”

Izuku snorted, then laughed a little, wiping his mouth with a napkin. “Half-vampire guy, huh?”

“Yup,” Kirishima grinned. “Hero name pending.”

Izuku looked at him, heart swelling with gratitude. “Thanks, Kirishima.”

“Anytime, bro. Seriously. If you ever need someone to talk to or like, a blood bag delivery service, I got your back.”

Izuku smiled, and this time, it wasn’t forced. “Tooth bros?”

“Tooth bros,” Kirishima said, holding out a fist.

Izuku bumped it with his own.

Kirishima stood and stretched, glancing toward the door. “Hey, if you're feeling better… maybe we can train sometime after school?”

Izuku’s face lit up. “Yeah! That would be awesome.”

“How about today? After classes?”

Izuku nodded enthusiastically. “Totally. I could really use the practice anyway… especially with all these new changes.”

Kirishima gave him a thumbs up. “Cool. I’ll come get you when the final bell rings.”

He turned to leave, tossing a grin over his shoulder. “Get some rest, Tooth Bro.” He said with a wink. 

Izuku chuckled to himself as the door shut behind him, warmth blooming in his chest. Maybe this whole vampirism thing… wasn’t going to be the end of the world after all.

Izuku hoisted himself up, he walked over to his dresser and began picking out a clean school uniform. He gathered his things and began making his way to the locker room, looking forward to a much needed shower. 

 

The locker room was quiet this time, everyone else had already had there morning shower and began eating breakfast. Can I even have real food now? The thought pestered in the back of his head.

He stood in front of the mirror, half undressed, towel slung over his shoulder. He leaned forward, both hands gripping the edge of the sink, knuckles pale from tension.

He stared at his reflection. His eyes… were still green. Mostly. But now, a thin ring of red glowed faintly around the edge of his irises like burning embers hidden beneath the surface. They weren’t glowing brightly now, but he could tell. The red shimmered like a warning, not hungry yet, but always waiting.

He opened his mouth slowly, fangs catching the overhead light. Longer than they had been yesterday. Sharper too. When he pressed his tongue against one experimentally, he felt the slight sting of pressure.

He looked… less like himself.

“I still look like me,” he whispered, as if saying it out loud would make it more true. “I’m still… me.”

But his voice trembled.

He pushed off the sink and turned away quickly, stripping the rest of his uniform off and stepping into the nearest shower stall. The hot water hit him like a wave, comforting at first. He closed his eyes and let it wash over his face, trying to scrub away the sick feeling curling in his gut.

He grabbed the shampoo bottle and gave it a squeeze. A comically large glob splattered into his palm, and some even dropped onto the floor.

“Crap!” He winced, trying to scoop it back up, but the suds just spread across the tiles. He used the little product in his hands and began to scrub the sweat and dirt from his scalp.

Next reached for the conditioner POP! He accidentally snapped the lid off the top entirely.

“What the…?” A frustrated growl escaped him, and he tossed the lid aside, rubbing the product into his hair as gently as he could manage. But even gentle felt too strong.

He finished quickly, shutting off the water and grabbing his towel. Back at his locker, he tried to calm himself. Just get dressed. Everything’s fine. It’s just a new normal.

He dried off, pulled on the clean pair of pants and undershirt. His fingers moved to the top button of his shirt.

Snap! The button shot off like a bullet, clinking loudly as it bounced across the tiled floor. Izuku stared at it, frozen and then everything crashed over him at once.

His breathing hitched. His hands trembled as he grasped his wet hair in frustration. He cried silently at first, then a soft, muffled sob escaped him as he buried his face in his towel.

“I don’t want to lose control again...I don’t want them to be afraid of me. I don’t want to hurt anyone…” Tears streamed down his cheeks as he slumped down against his locker. "I don’t want to be a monster.” He pulled his knees up to his chest, clinging to the towel like it might keep him grounded. 

Izuku breathed out a few more sobs, he let a few more tears fall before dabbing them away with the towel in his hand. He knew he couldn't stay in that locker room forever, he had to get to class or else Aizawa was going to punish him for being tardy. 

Sniffling quietly, Izuku stood and grabbed his towel, drying off properly before pulling on his now-wrinkled uniform shirt, minus the top button. It sat slightly askew, but he didn’t have time to fix it. He ran a hand through his damp curls, trying to tame them as best he could, and then stepped back toward his locker to pack up.

He pulled the locker door open and tossed his dirty clothes in. I'll deal with those later he thought. Just as he was about to close his locker, something suddenly fluttered down towards him. 

“Ack!” he yelped, flailing his hands.

The paper danced on the air like a feather, and he barely managed to catch it against his chest with a dramatic gasp, heart pounding like it had been a villain attack.

He blinked down at it, puzzled. A simple folded note. He opened it carefully, brow furrowed. His breath hitched as he read the sharp, familiar handwriting:

“I washed your hoodie ‘cause it was covered in blood, dumbass.
Still haven’t gotten a thank you for saving your life."

-Bakugou

A beat of silence. Then his ears turned red.

“H-he… he washed it?” he whispered, stunned. He reached for the hoodie, which now sat neatly folded and clean on the shelf of his locker. The moment his fingers touched the fabric, the scent hit him.

Kacchan.

The world tilted slightly. His knees wobbled. The hoodie smelled like fresh laundry, but underneath was the unmistakable scent of him. Sweat. Spice. Fire.

Izuku’s face turned crimson.

“O-oh god…”

His mind was foggy, chest fluttering with something hot and embarrassed and dangerously distracting. He clutched the hoodie against his chest, trying not to let it show on his face.

And that’s when his brain traitorously decided to flash back.

The kiss.

The way Bakugou had looked at him. The hunger in his eyes. The way he had held his cheek as he pressed those warm lips against his. He also remembered the sting of his hand that came when it made contact with Bakugou's face. 

“I-I can’t think about that right now!” he squeaked. He smacked both of his cheeks lightly with his palms. Smack! Smack!

“Focus, Izuku! That’s a later conversation. A very important, very terrifying, later conversation. Not now.” He shoved the note and hoodie into his backpack hoisting it over his shoulder. 

“Just… get to class. Try not to embarrass yourself. One step at a time.”

Despite everything, the smallest smile pulled at the corner of his mouth as he walked out of the locker room, the scent of Bakugou still lingering faintly.

 

“You’ve got this. You’re still you,” he whispered to himself, grabbing the straps of his school bag nervously as he stood outside the classroom door. 

With a deep breath he tried to open the door quietly but ended up swinging it open too quickly, causing it to hit the wall with a loud BANG!

Everyone was already seated as they jolted up, startled by Izuku's loud entrance, all eyes were on him. 

His heart jumped into his throat. Oh no.

Aizawa raised a hand calmly. “Midoriya. Take your seat.” Izuku nodded stiffly and made his way to his desk in the front row, aware of every gaze tracking him. He tried to keep his head down as he slipped into the seat in front of Bakugou.

Aizawa looked at the class. “I have an announcement.” That was it. Izuku’s stomach dropped.

Aizawa’s tone remained neutral, “As some of you may have heard, Midoriya was injured during an encounter with a villain off campus. As a result, he’s going through some... temporary changes.”

He looked to Izuku, who gave a sheepish nod.

“These changes include enhanced senses, possible behavioral shifts, and a need to consume blood for nourishment. To be clear, this is not a villainous transformation. Midoriya is still himself and remains a student of Class 1-A. He will be receiving supervision and blood packs provided by the school.”

The room was quiet for a beat.

Then Mina raised her hand. “Wait… so like, Midoriya’s kinda like… a vampire now?”

Aizawa blinked. “That’s… a crude way to put it, but not inaccurate.”

Instead of fear or tension, a wave of excitement and curiosity swept through the class.

“Oh my gosh, that’s so metal!” Denki blurted, grinning.

“Do you have fangs now?” Mina asked, leaning forward.

Izuku turned red, ducking his head. “Y-Yeah… a little.”

Sero grinned. “That’s actually kinda badass!"

Jirou raised her hand. “If you ever run out of blood bags… I mean, I don’t mind helping. Just saying.”

“I-I’d help too!” Uraraka piped up, waving her hand nervously. “If it’s safe, I mean!”

A chorus of agreements followed, Tokoyami gave a solemn nod, Iida raised his hand with a dramatic “As a classmate and friend, I offer my full support,” and even Todoroki gave a quiet, “You can count on me if needed.”

Izuku blinked fast, eyes suddenly stinging. “I… I don’t even know what to say…” Izuku pressed his hands against his eyes, trying not to cry, and muttered, “Th-thank you, everyone…”

Behind him, Bakugou sat stiffly with his arms crossed, glaring at the back of Izuku’s head. “Bunch of damn extras acting like it’s the Deku Fan Club now,” he muttered under his breath.

He watched as Mina leaned over and offered Izuku a little wrapped candy to cheer him up, as Kaminari reached out to fist bump him, and Uraraka smiled softly like she was going to cry, too.

Jealousy sparked in Bakugou’s chest like wildfire. He looked away, biting the inside of his cheek. Tch. Damn nerd. Why the hell does everyone care so much?

Still, he didn’t say a word, just leaned back in his seat, simmering quietly while the rest of the class made Izuku feel like he belonged.

Aizawa clapped his hands "Alright alright, we have to get this lesson started, everyone back to their seats." 

 

Before long the final bell rang echoing through the halls. Chairs scraped, notebooks shut, and Class 1-A stirred to life. Aizawa gave a tired grunt and dismissed them all with a wave of his hand before sinking into his yellow sleeping bag.

Bakugou was on his feet in an instant.

Without a word, he stormed out of the classroom, his boots slamming against the floor with every step. The door slammed shut behind him hard enough to make the glass rattle.

Izuku flinched at the sound. He didn’t even say anything all class. Didn’t even look at me.

There was something coiled tight in Izuku’s chest; confusion, concern, and something that almost hurt. But he didn’t have time to untangle it.

“Yo!”

Izuku jumped slightly as Kirishima appeared beside him, already half out of his uniform and sporting his sleeveless training gear. “Still down to train?”

“Oh! Yeah!” Izuku scrambled to his feet, trying to shake the fog from his head. “Totally! I’ve been meaning to test out these new powers”

Kirishima grinned. “Cool! Come on, let’s head to one of the outdoor training fields before someone else snags it.”

The sky above was a moody gray when they stepped out onto the dirt training ground behind the dorms. Clouds loomed, heavy and thick, but it wasn’t raining, not yet.

“Cloud cover,” Kirishima said, glancing up as he rolled his shoulders. “Guess that’s lucky for you, huh?” Izuku chuckled nervously. “Yeah. Sunlight doesn’t burn me exactly, but it’s… uncomfortable.”

“Well, cloudy’s perfect then,” Kirishima said, cracking his knuckles. “Let’s go!”

They squared off across from one another, stretching and warming up. Kirishima braced his arms and activated his quirk, skin hardening into jagged stone.

Izuku took a breath and let his own powers flow. That familiar, eerie strength surged through him, the vampire part. His muscles coiled tighter than they used to, and when he moved, it was almost too fast.

They clashed.

It started light; sparring jabs, blocks, dodges. But as they warmed up, their pace quickened, feet kicking up dust in the ring.

Izuku’s senses sharpened. He could hear Kirishima’s breath, see the shift in his stance before he moved. His heartbeat. And with a sudden burst of speed, he dashed past his friend’s guard and flipped him clean off his feet.

BAM!

Kirishima hit the ground with a surprised oof, then laughed. “Okay, okay! You win, bro!”

Izuku stood over him, panting slightly, his eyes still glowing faintly red from the rush. “S-sorry, I didn’t mean to go so hard!”

“No, dude! That was awesome!” Kirishima said, sitting up and rubbing his head. “You’re seriously getting stronger. Vamp powers or not, that was sick.”

Izuku smiled, bashfully rubbing the back of his neck. “Thanks. It… felt good, actually. To move like that.”

“Yeah, you’re gonna be unstoppable once you get used to it.”

But then,

A scent.

Iron. Sharp and warm. Blood.

Izuku froze.

His nose twitched and his pupils shrank. Slowly, like a camera lens focusing, his gaze dropped to Kirishima’s leg. A jagged scrape bled along his shin, staining his pants.

Kirishima followed his eyes, then winced. “Oh. Crap.”

Izuku took a step back, hands shaking slightly. “K-Kirishima, I-I didn’t mean to hurt you!”

“No, no, it’s nothing! Just a scrape,” Kirishima said quickly. But his voice wavered when he noticed Izuku’s glowing eyes, his fangs peeking from behind parted lips.

Izuku swallowed thickly. “I shouldn’t be reacting like this. I already fed this morning… I shouldn’t be hungry…”

But the scent tugged at his instincts. The blood called to something in him he didn’t understand. His breath hitched.

“I can heal it, your wound but...” he whispered, squeezing his eyes shut. “I don’t want to lose control. What if I hurt you?”

“You won’t,” Kirishima said gently.

Izuku shook his head. “You don’t know that.”

Kirishima sat patting the ground next him. "Hey it's a win win. I get healed, and you get a refreshing drink. Plus if you were to lose control all I have to do is activate my quirk and you won't be able to peirce my skin." 

Izuku crouched down beside Kirishima, shaky hands reached out to grab his knee. His eyes locked onto the crimson leaking from the scrape. His throat went dry.

“Are you sure?”

“Positive.” Kirishima smiled, even if it looked a little nervous. “I trust you, Tooth Bro.”

That did it.

Izuku scooted closer, hands trembling as he raised Kirishima's leg, one hand bracing lightly on Kirishima’s knee, the other cupping his ankle. Kirishima’s breath caught, but he didn’t move.

Izuku leaned in, breath brushing warm against Kirishima’s skin.

His fangs extended against his will. He hesitated.

“It’s okay,” Kirishima whispered, voice barely audible.

Izuku nodded faintly. His tongue darted out gently licking against the shin. 

Warmth bloomed across his tongue. Not like the bagged blood, this was fresh, strong, alive. It hit something in him, a jolt of hunger he quickly tried to suppress.

He tried to resist the urge to sink his fangs, to pierce skin, but the few drops of blood he was lapping up wasn't enough. 

"Kiri...I'm sorry..." He said looking up into Kirishima's eyes with his glowing red orbs before he gave in. 

His eyes shut tightly as achy fangs sunk into the soft skin, piercing them with a loud pop. Kirishima winced but stayed steady as pain soon turned into a warm pleasure.

Waves of sensations were sent from where Izuku's mouth sucked at sensitive skin, sending them all the way up leg, to his thigh and into his groin. 

Kirishima covered his mouth to muffle a moan trying to escape. What the hell? Is this normal? He thought as his mind began to grow fuzzy. 

A slight blush spread over his cheeks as he looked down to Izuku, blood dripped down his chin as he watched his Adam's apple bob in his throat, gulping greedily. His nails dug into his skin slightly as trembling hands gripped onto him for dear life.

Kirishima tried to focus on something else but he couldn't ignore the length hardening in his pants as he felt himself drifting further and further into bliss. 

The outside world seemed to disappear as his hearing became muffled and his eyes began to unfocus. Body feeling heavy as he slowly rested back on his elbows, heartbeat quickening in his chest,  breath coming out in small pants. His head flung back as he looked up at the cloudy sky above. 

He argued with himself in his mind knowing things were getting out of hand, going to far. But he didn't care, all he could focus on was the pleasurable sensations overcoming his body, putting him in a trance. 

A cool rain drop kissed his cheek, startling him a little bit, bringing him a bit of clarity for only a moment before he was sent right back into that pleasurable state. 

But then there was another, and another until he was finally snapped back into reality. He blinked his eyes a couple times, a soft sound catching his attention.

 "..mhmm.." 

He looked down at Izuku, eyes half lidded, pupils wide rolling back in ecstasy. 

Shit! It was too much, too hot. He knew he needed to stop things before they both did something they'd regret later, but Kirishima was thinking with the head in his pants instead of the one on his shoulders. 

Rain drops fell cooling his hot body as he tried to think on what to do next. He knew Izuku was unstable in this state and didn't want him to turn on him out of frustration. 

He gently placed a hand in Izuku's wild green curls and lightly scratched his scalp. "Hey...Zuku, you still with me?" He questioned softly. 

Izuku flinched slightly at the touch, eyes blinking a couple times before the green in his eyes slowly washed away the red glowing embers. 

Izuku jerked away, a loud POP following where his mouth had been. 

A deep purple bruise and teeth marks slowly began to melt away, Kirishima's body healing the abuse Izuku's mouth had caused. 

Izuku sat back on his knees panting with his tongue out, blood staining his fangs and chin. The cool rain cleared his hazy mind as clarity washed over him.

He looked up at Kirishima, red painting both of their cheeks.

Izuku’s eyes widened. “Are you okay?!”

Kirishima gave a dazed little laugh. “Yeah. Just… tingly. And a little lightheaded. That was kinda crazy.”

The rain began to fall harder as Izuku helped Kirishima up from the ground and they quickly gathered their things. The two of them ran to a nearby rest room next to the training grounds.

Their wet shoes squeaked as the stumbled in, both of them soaked. Kirishima sat his gym bag down as he sat on top of the edge of the bathroom sink. 

Without hesitation Izuku was reaching for his backpack, grabbing a small sports drink and a protein bar. “Here! Eat something, and drink! Please!”

Kirishima took them with a chuckle. “You really are still you, huh?” Izuku blinked at him, stunned. “You’re worried about me more than yourself. Even after all that.”

Izuku blushed hard, looking away. “Of course I am, it's the least I could do after all...that!" He said flailing his arms.

He watched in awe as Kirishima clutched the sports drink and began to down it all in one go.

He tried not to stare but his eyes began to wander, he had never really noticed before but Kirishima actually looked pretty hot.

His eyes subconsciously drifted down from his face, down his toned chest, until his eyes locked on it, the obvious tent that had formed in Kirishima's pants. 

Kirishima noticed immediately and almost choked on his drink in embarrassment ,"..s-sorry about that...it must of happened earlier while you were, um...yeah." He said awkwardly closing his legs.

"No-no it's ok! I um...got a little excited too. It-its just a weird effect of the quirk I guess...I didn't mean to stare.." Izuku said scratching the back of his neck. 

Kirishima threw his head back in laughter "Heh! Yeah that's one wild side effect. Forget being a vampire I think you might be an incubus instead." 

He tried to joke about it to cheer the poor greenette up but he could tell he was still bothered and embarrassed, could tell his mind was swarming with thoughts so he tried again to reassure him. 

He set the empty bottle down beside him and wiped his mouth with the back of his hand. The flush in his cheeks hadn’t faded, but his smile was warm, genuine.

“Hey,” he said gently, voice softer this time. “It’s okay, really.”

Izuku blinked, startled by the calm in his voice. “Y-you’re not weirded out? Or like… grossed out?”

Kirishima chuckled, leaning forward slightly, resting his arms on his knees. “Nah, man. I mean, yeah, that got kinda intense, but we both kinda lost control there. It’s not like either of us planned it. It just… happened.”

Izuku fidgeted, gripping the straps of his soaked backpack. “But I-I didn’t stop myself. I felt it getting out of hand and I still… I still kept drinking. And it-it felt good to just let go and let my instincts take over...” His voice cracked as he hid his face in his hands "I’m so sorry.”

Kirishima laughed again, not mocking, just amused and kind. “Dude. Seriously. Chill.”

He leaned back slightly on the sink, water dripping from his red hair onto the tile. “Look… I know it was awkward. Weird even. But it doesn’t change anything between us, okay? You’re still my bro. My Tooth Bro.” He gave him a small, toothy grin.

Izuku peeked through his fingers, eyes wide. “But the… uh… stuff that happened…”

Kirishima’s smile grew a little sheepish, and he shrugged. “So our bodies did some stuff. Big deal. It’s biology or whatever. You’ve got this intense quirk mutation now, and apparently your feeding’s got some… side effects. Doesn’t mean you wanted it to go that way. Doesn’t mean I did either.”

He looked Izuku in the eye.

“It doesn’t make you a bad person. Or a monster. It just makes you someone going through something big. And I’m not gonna let you go through that alone.”

Izuku’s throat tightened.

A breath shuddered out of him as he lowered his hands, rainwater and tears mixing down his cheeks. “Kirishima…”

Kirishima stepped forward, resting a hand gently on Izuku’s damp shoulder. “You’re still you. That’s what matters.”

Izuku’s lip trembled. “What if next time I lose control and I can’t stop and end up doing something really bad I regret later?" 

“Then we’ll work on it,” Kirishima said firmly. “We’ll train for it. Just like you trained to control One For All. You’re not alone. You’ve got people who care about you, Izuku. Me. Uraraka. Todoroki. Hell, even Bakugou in his own… explosive way.”

Izuku gave a wet little laugh at that, sniffing hard.

“And yeah,” Kirishima added with a smirk, “if things get a little awkward sometimes because your vampire instincts are, uh… a little spicy, we’ll deal with it. You can put your trust in me." 

Izuku’s face turned red again, but this time he smiled, shy but warm. “Thanks, Kiri.”

Kirishima gave him a small fist bump. “Tooth bros forever?”

“Tooth bros,” Izuku echoed, bumping his fist.

They stood in silence for a moment, the rain still tapping softly on the bathroom roof. The awkward tension that had buzzed between them had eased, replaced with something calm. Familiar.

Kirishima suddenly grinned. “Also, just saying, if you are part incubus, I expect a cooler hero name. Like, ‘Hump-King Deku’ or something. Add some edge.”

Izuku let out a snort. “I am not calling myself that.”

Kirishima winked. “We’ll work on it." 

The two left the bathroom giggling unaware that a spikey haired blonde had been sitting in the bathroom stall the whole time, face red with jealousy. 

 

Chapter 4: The Confession

The classroom buzzed with low chatter as Class 1-A trickled in, chairs scraping and backpacks dropping to the floor.

Bakugou sat in his usual seat, arms crossed, jaw tight.

He hadn’t said a word all morning. Not even when Denki tried to joke with him. Not even when Iida asked about the homework. His crimson eyes hadn’t moved once from the back of Izuku’s head.

They were practically burning holes through it.

Izuku could feel the glare. The weight of it made his shoulders tense, but he didn’t dare look back. Not after yesterday. Not after what happened with Kirishima. Not when he still didn’t fully understand why it had felt so… good.

He swallowed hard and scribbled notes onto his paper, trying to focus.

But he could feel it.

The stare.

Still there. Still heavy. Still angry.

The lunch bell rang as students fluttered out into the halls, some deciding to stay and eat lunch in the classroom, others going to the cafeteria.

Izuku stood up slinging his backpack on his shoulders, blood bags resting in a cooler at the bottom. 

“Yo!” Denki bounced up beside him, grinning. “Lunch time, let’s go! I’m starving.”

Sero slung an arm around his shoulders. “You coming, Midoriya?”

Kirishima appeared a moment later, a casual smile on his face as he nudged Izuku’s shoulder. “Yeah, man. Join us?”

Izuku hesitated, gripping his backpack straps nervously.

“I-I think I’m gonna skip lunch. I don’t… really eat much anymore. Not the way I used to. Not since the whole, uh...” he gestured vaguely at himself, “...vampire thing.”

Bakugou, just a few steps behind, muttered under his breath:
“...didn't stop you yesterday.." 

Izuku blinked. “What?”

Bakugou’s expression didn’t change as he shoved his hands into his pockets. “Nothing. Whatever. Y’all gonna keep standing around or are we leaving?”

The group exchanged confused looks but followed him.

 

They found their usual spot near the back. Plates clattered, trays were set down, and laughter echoed across the cafeteria.

Izuku sat silently at the end of the table, cradling his backpack in his lap, avoiding eye contact. His stomach churned, with hunger.

He hadn’t fed since yesterday, since...he fed from Kirishima. 

He had told Izuku everything was fine but it was still kinda awkward to just go along like nothing had happened, and on top of it he still had to have the conversation with Bakugou about the kiss.

Was it too much to ask for just a single day of normalcy? 

Izuku was interrupted mid thought by a painful cramp squeezing his stomach. He tried to ignore his hunger but he could hear the heartbeat of his peers teasing his ears, reminding him that normalcy wasn't possible as long as he was cursed with this quirk. 

A bead of sweat ran down his forehead and his fangs began to ache, eyes glowing scarlet indicating it was time to eat. 

“Uh, hey… you good, dude?” Denki asked, setting down his chopsticks, eyes locking on his.

"Yeah dude you look pale and your eyes are glowing!" Sero chimed in.

Izuku gave a weak smile. “Y-yeah! Totally fine. Just…they do that when I'm hungry."

"Well..." Sero scratched his cheek. “If you need blood, I’ve got a band aid and a very low pain tolerance.”

Denki grinned. “Yeah, same. You can nibble on me if you want.”

Kirishima nodded. “You know I don’t mind either.”

Izuku’s face flushed deep red. “N-no! Thank you, but no! I, uh...I brought something.” He unzipped his backpack and pulled out a blood bag, still cold from the small ice pack inside.

Everyone quieted as they watched in curiosity.

Izuku held the silver bag with shaky hands as he brought it up to mouth. Sharp fangs teased the edge right before piercing it in one swift move. 

Izuku shut his eyes tightly as he gulped the blood down, relief washing over him as the painful hunger in his stomach melted away. 

After squeezing out the last drop, he opened his eyes and retracted his fangs. Panting slightly as a bit of blood trickled down his chin. 

Kirishima handed him a napkin, a slight blush on his cheeks. "Here Zuku, you have a little...right there." He said pointing at his chin.

"Ah, so-sorry about that. I get a little carried away sometimes...thanks Kirishima." 

Bakugou sat in silence, tapping his foot impatiently as he watched the interaction between the two. Jealousy burning in his stomach.

Izuku grabbed the napkin gently as he dabbed the blood from his chin. Tossing it and the empty blood bag into the cooler in his backpack. 

Everyone seemed to go back to eating their lunch like normal after that, everyone except Bakugou.

Izuku could tell something was bothering him by the way he sat restlessly, glaring at him with an unreadable tension. 

Suddenly

“Tch.” Bakugou’s voice sliced through the tension. “I don't understand you. You had no issue drinking from Kirishima yesterday. So what’s with the hesitation now?”

Izuku stiffened, completely caught off guard. “W-What?”

“WHAT?!” Denki and Sero yelled in unison, whipping their heads toward Kirishima.

Kirishima froze, red creeping up his neck. “Bakugou, dude—not cool.”

Izuku stood up, hands trembling. “Thats not any of your business. I can choose who I feed from. It’s my choice.”

Bakugou’s eyes narrowed. His fists clenched on the table.

“Oh yeah?” he snapped. “Because two days ago you were bitchin' about what Recovery Girl said, acting like this feeding thing was some tragic burden. Then you go and lose control on him.”

He pointed a finger toward Kirishima. “No hesitation. No warning. Just fangs out and no second thoughts .”

“Bakugou, enough,” Kirishima said sternly, locking eyes on him.

Bakugou stood. His chair screeched against the tile. “You bit him. You lost control, Deku. Don’t act like you’ve got it all figured out.”

Izuku’s eyes burned red, not from hunger, but from the heat rising behind his eyes.

Izuku’s fists curled at his sides. His heart pounded in his ears. And that was it-

“FUCK YOU!”

The cafeteria froze.

Every pair of eyes turned toward them. Toward Izuku. The boy who never cursed. The boy who always smiled and apologized too often.

Bakugou hesitated, just for a second. Like he wanted to say something else. But then his face hardened, and he turned on his heel.

“Tch. Whatever.”

His loud combat boots echoed across the tile as he stormed out of the quiet cafeteria. Doors slamming behind him.

Denki and Sero stood back, fear in their eyes as they flicked between Kirishima and Izuku. 

Kirishima opened his mouth to say something but his voice caught in his throat unable to speak.

Tears welled up in Izuku's eyes as he looked away, in shame. "I-I should go" 

Without a second thought, Izuku bolted from the cafeteria in a blur, tables rattling and trays skittering in his wake. 

"Ah-huh! Did y'all see that!?" Sero said in shock.

"I guess Izuku has super speed now..." Denki chimed in scratching the back of his neck. 

Kirishima just stood there, contemplating on what to do next. 

 

The bathroom lights buzzed softly overhead, casting a fluorescent glow across the pale tiles.

Izuku sat curled on the toilet seat inside the last stall, arms wrapped around his torso, forehead resting against his knees. His breath trembled. The silence pressed in on him, thick and suffocating. Every now and then a hiccup escaped his throat, broken and wet.

What is wrong with me? he thought. Why did I yell? Why can’t I control it?

The cafeteria replayed in his head like a nightmare on loop. The stares. The shock. Bakugou’s voice angry, disappointed. And then his own voice, screaming back. The word fuck burned on his tongue still.

He wasn’t that kind of person. He was supposed to be kind. Strong. A hero.

But heroes didn’t drink blood. Heroes didn’t lose control. Heroes didn’t want to bite their classmates. “...what kind of hero am I becoming..” he whispered to himself, voice cracking. “I’m not even human anymore…”

A fresh wave of tears spilled down his cheeks. He pressed his hand over his mouth to muffle the sob.

Then, just as he thought he was alone, the bathroom door swung open with a loud creak, followed by heavy, stomping footsteps.

And yelling.

“Damn it! DAMN it!” Bakugou’s voice echoed off the tile. “What the fuck is wrong with me!?”

Izuku’s eyes widened.

“I’m such a dumbass,” Bakugou growled, pacing in front of the sinks. “Stupid, STUPID. Why’d I say all that shit?!”

There was a loud bang as something hit the sink, probably Bakugou’s fist.

“Uhhh! Fuck, why does he make me feel like this!?”

Izuku’s breath caught in his throat in shock.

Bakugou kept going, his voice hoarse. “I kissed him. I let him drink my blood. And now...now I’m acting like it was his fault-” He cut off with a frustrated yell. "And now I'm in here yelling to myself! Fucking batshit!"

Izuku sat frozen in the stall, unsure whether to laugh, cry harder, or melt into the floor.

There was a long silence. Then Bakugou muttered, quieter this time, “…I think I love him.”

Izuku’s heart nearly stopped.

There was a moment—just a beat—before Bakugou sighed and looked up into the mirror above the sink. And then his eyes locked onto the reflection of someone’s foot sticking out under the last stall.

He stiffened. His expression darkening.

“…Who the hell is in here?”

No response.

“Whoever the hell is in here better come out before I blow the damn stall door off its hinges!”

Izuku flinched and slowly, with shaky hands, reached for the lock. The door creaked open.

Bakugou’s eyes went wide for a split second. His mouth dropped open.

“...fuck..FUCK!” he shouted, face going red.

Izuku peeked out, eyes glassy, voice small. “K-Kacchan…”

Bakugou groaned loudly and dragged a hand down his face. “Are you kidding me?! How long were you in here?!”

“…Since before you came in,” Izuku admitted.

Bakugou looked like he was about to punch the air. “You heard all that!?”

Izuku nodded slowly. His cheeks were blotchy and damp, his lashes clumped from crying.

Bakugou cursed again under his breath and turned away, gripping the edge of the sink like it might keep him from falling over.

For a moment, neither of them spoke.

The bathroom was quiet, except for Izuku’s soft sniffles and the harsh breathing coming from Bakugou.

And then, in a tiny voice, “I’m sorry for yelling at you.”

Bakugou looked up, confused. “Why the hell are you apologizing?”

Izuku hugged his arms to himself. “Because… I lost control. Again. And I’m scared. Of myself. Of what I might become.”

Bakugou stared at him through the mirror.

“…Join the club,” he muttered.

After a long moment Bakugou huffed through his nose, pushed off the sink, and stalked toward the stall.

“Move over. I’m coming in.”

Izuku blinked rapidly. “W-What!?”

Bakugou ignored him and shoved the stall door open the rest of the way. Before Izuku could react, Bakugou was already closing the door behind him, locking it. He sat down on the floor right in front of the toilet, his arms draped across his knees like it was the most normal thing in the world.

Izuku flushed instantly, back straightening, trying to make himself smaller. They were so close. Closer than they’d been since-

“I wanna talk,” Bakugou said, voice gruff. “And this is the only way I can do it without you running off again.”

Izuku’s breath caught. He looked down at Bakugou, his expression tight, frustrated, and weirdly... nervous?

Izuku gave a tiny nod, swallowing thickly.

Bakugou didn’t meet his eyes. He rubbed the back of his neck and muttered, “I wanna talk to you about… about…”

“Damn it,” he growled, “I can’t even say it!”

Izuku flinched at the sudden sharpness in his tone.

 “Shit. Sorry. I didn’t mean to yell. Just..ugh.” He let out a deep sigh, running a hand down his face. “I’m not good at this. I wanna talk to you about… the kiss.”

The word hung in the air like a spark.

Izuku’s breath hitched. His heart skipped a beat, body tensed up stuff like a statue. 

“The kiss,” he echoed softly, barely above a whisper.

Bakugou still didn’t look at him. His ears were tinged pink. “Yeah. That. The one we haven’t talked about. The one that’s been driving me fucking crazy.”

Izuku looked down at his lap, hands gripping his knees.

“…Me too,” he whispered.

Bakugou stayed quiet for a long moment. His gaze was fixed on the floor between them, jaw clenching and unclenching like he was trying to choke the words out.

“I’m sorry.”

Izuku blinked, startled. “…What?”

Bakugou looked up at him, brows furrowed. “For kissing you that night. In the infirmary. After you got bit.”

Izuku’s heart stuttered in his chest.

Bakugou ran a hand through his messy hair, frustration brimming just behind his eyes. “I just..fuck, I couldn’t help it. You looked so… fragile. But not weak, just… real. You were hurting, bleeding, but still breathing, I thought I lost you. And those big eyes of yours, your dumb freckled cheeks, those-” He bit back the rest for a second, but then continued on “Your plump lips. It all just… drew me in. Before I knew it, I was leaning in and…”

He looked away, scowling at the floor like it personally offended him.

“…The worst part is that I don’t even regret it.”

Izuku’s breath caught in his throat. He stared at Bakugou, lips slightly parted. Then he looked down, guilt tightening his chest.

“I… I slapped you.”

Bakugou snorted softly. “Yeah. You did.”

“I’m sorry,” Izuku said quickly, voice small but sincere. “My senses were all over the place, and everything was so overwhelming. I’d just been attacked, and I-I didn’t know how to process any of it. I was an emotional rollercoaster and… I panicked.”

Bakugou shook his head. “Don’t apologize, damn it. I was the one who crossed the line. I shouldn’t have kissed you without your permission, especially after…” he hesitated, shame flashing in his eyes, “...after all the years I treated you like shit.”

Izuku looked down at him, curiously.

“Yeah… why did you do that in the first place?”

Bakugou’s eyes darted to the side as his face went scarlet.

“I—I don’t know! I just…” he clenched his fists in his lap. “You always made me feel things I didn’t understand. Made me feel weak. And I hated it. I hated you for it. Because every time I saw you, I felt these… feelings that only weak people are supposed to feel.”

His voice cracked slightly as he went on, almost bitter, like he was confessing to a crime.

“It’s not normal. I don’t feel this way around anyone else. Just you. So it made me want to crush you. Crush whatever the hell it was.”

Izuku stared at him, wide-eyed, completely stunned.

Then he let out a small, incredulous chuckle.

“So… it sounds like you had a crush on me,” He said, a little smile creeping onto his lips, “But instead of telling me, you just tried to crush me?”

Bakugou’s mouth fell open, and he sputtered, “Wh-! That’s not-!”

But the corner of Izuku’s lips twitched again, and Bakugou groaned, dragging a hand over his face.

“God, you’re so fucking annoying.”

Izuku giggled.

And for the first time in days, the air between them didn’t feel so heavy.

Bakugou leaned back slightly on his heels, still crouched in front of Izuku in the cramped stall. His brows furrowed, like he was trying to piece something together in his head before finally grumbling,

“…So now what?”

Izuku blinked, caught off guard. “Huh? What do you mean?”

Bakugou let out a short, frustrated breath. “I mean, now what, dumbass! What do we do? Do you like me back or not?”

Izuku’s whole face flushed. “W-What?! I—I don’t know!” His hands curled tightly in his lap. “Everything’s been… so much lately. The bloodlust, my body changing, the instability. I’m scared of hurting someone. Of hurting you. What if I lose control again?”

Bakugou tensed, his jaw shifting. His voice dropped into something tighter. “Yeah, well… too late for that.”

Izuku blinked at him. “Huh?”

“I was in the bathroom the other day,” Bakugou muttered, not looking at him. “Heard you and shitty hair talking about you drinking his blood.”

Izuku’s eyes widened in horror, then he realized. “Wait, that’s why you were acting so weird in the cafeteria?”

Bakugou’s head snapped up, a scowl already forming. “Don’t act surprised, Deku. You practically climbed into his lap!”

“Kacchan!” Izuku yelped, his ears burning. “That’s not...it wasn’t like that at all!”

“Oh yeah?” Bakugou scoffed. “Sure sounded like you two were one heartbeat away from ripping each other’s clothes off.”

Izuku covered his face with both hands. “Oh my god, stop! Yes, things got a little… intense, but it wasn’t anything like what you’re thinking!”

Bakugou narrowed his eyes, still angry, but his fists weren’t clenched anymore.

Izuku dropped his hands, shoulders slumping. “This is what I mean, Kacchan. My instincts, they’re all over the place. And I don’t want to lead you on. I don’t even know what’s mine anymore. What’s me.”

For a second, Bakugou didn’t say anything. His expression tightened like he was chewing on glass.

“…Fine.”

Izuku looked up at him, startled. “Huh?”

“I won’t go off acting like a jealous prick again,” Bakugou muttered. “Just… don’t shut me out. Promise you’ll give me a chance.”

Izuku’s lips parted, words caught in his throat.

Bakugou leaned his elbows on his knees, eyes intense but calmer now. “Besides… I know no one’s blood compares to mine.”

Izuku stared at him. “W-what?”

Bakugou gave cocky smirk “C’mon. You know it. I’m not just some donor bag with muscles.”

He slowly stood, eyes never leaving Izuku’s as he reached his full height and stepped forward,  just close enough to make Izuku’s heart stutter.

Izuku squeaked, shrinking back slightly. “K-Kacchan?”

Bakugou braced one arm against the wall of the stall, leaning in without touching him, eyes locking with his. “So how about this, huh?”

Izuku swallowed thickly.

“You take my blood. And I take my shot. Let me prove its not just some crush.” His voice dropped into a husky whisper. “Let me show you how easy it’ll be to fall for me.”

Bakugou cupped Izuku's cheek gently, tilting his chin upwards.

“All you have to do is say yes,” he murmured, voice thick with heat, sending a shiver down Izuku’s spine.

Izuku shut his eyes tightly before letting out a soft spoken-

"...yes..." 

Warm lips clashed with his, head going dizzy as he melted into the touch. Izuku's hands hesitated before resting in blonde tufts of hair. 

The familiar scent of spice and smoke filled his senses as the kiss deepened, turning molten with desire.

But it wasn’t enough.
That primal voice in the back of his mind whispered louder now, let go, give in, take what you want.

Before he could pull back, he felt his fangs extend, just enough to graze the edge of Bakugou’s lip.

Bakugou winced, startled, pulling back slightly. He ran his tongue across his bottom lip, tasting the metallic tang.

Their foreheads rested against each other, hot breaths mingling as they tried to catch their breath.

Bakugou''s red orbs locked with Izuku's, embers burning in the dull bathroom light. 

Bakugou's low chuckle cut through the silence, "Hey nerd...I've got you glowing already." 

“K-Kacchan...”

Without hesitation he grabbed the front of Izuku’s uniform and pulled him in, deeping the kiss. Harder, hungrier. 

Izuku’s mind short-circuited as the taste hit his tongue. Blood; sweet, warm, intoxicating. 

Rationality slipped away, drowned beneath instinct, until there was nothing left but desire.

Izuku let it take over, lunging forward , freeing his hands from Bakugou's hair and hooking them under his thighs. 

Before Bakugou could process what was happening he felt his back hit against the stall door with a loud thud.

Shit! his mind reeled as Izuku sucked his bottom lip into his mouth. Where the hell did he learn how to do that!?

Just when the sharp sting grew too intense, it was soothed. Replaced by a familiar, tingling warmth that spread through him like static.

Bakugou’s breath hitched.

It was already too late to turn back.

So he didn’t.

He let go, allowed Izuku take control, set the pace, and  push things further. Izuku held him up effortlessly, pinning him in place like he weighed nothing at all. 

But it still wasn't enough.

In one swift motion, Izuku darted out his tongue, colliding it with Bakugou’s in a sudden burst of heat.

They both moaned. Low, breathy, tongues tangling in a steady rhythm as their minds blurred.

Bakugou swore Izuku was sucking the soul right out of him. Hell, if he asked, he’d probably let him.

But somewhere in the haze, a sliver of clarity cracked through.

Shit... this is turning into a full-on snogfest.

He knew Izuku was fine with the kissing. But this?

This was getting carried away.

Bakugou gently placed his palms on Izuku's chest, pushing him back with a light touch.

Izuku took the hint as he pulled back from the kiss. A string of saliva lingered between their lips.

"T-time..." Bakugou shuttered out, trying to catch his breath. 

Izuku blinked, his eyes still tinged red, glazed with vampiric hunger.

"You-you ok...Kacchan?" He asked softly, unsure.

“Yeah,” Bakugou said, voice a little steadier now. “I just wanted to make sure you were okay with… all this.” He gestured vaguely to their position; his back against the stall door, legs still around Izuku’s waist.

Color bloomed up Izuku’s neck as he loosened his grip on Bakugou’s thighs.

“Oh-uh, yeah, sorry… I guess I got a little carried away.”

But just as Izuku began to lower him, Bakugou protested.

“Nah, it’s fine, nerd. I just… wanted to make sure you didn’t do anything you’d regret later.”

Izuku’s playful expression fell into something more serious. He looked deeply into Bakugou’s eyes.

“Katsuki… this is a moment I’ll never regret.”

Bakugou’s eyes widened in shock. Katsuki?
Izuku never called him that.

A flush crept across Bakugou’s cheeks as he reached up to his collar, loosening his tie and unbuttoning the first button.

"..I want you to bite me..,” he murmured, turning his head and baring his neck.

“B-But I’ve never fed from someone’s neck before,” Izuku said, hesitating. “What if I hurt you?”

But Bakugou didn’t care. He reached out, fisting the back of Izuku’s hair, and pulled him in.

“I don’t care. Just do it… Come on. I know you want to.” Voice teasing.

And damn, did he want to.

Izuku could hear Bakugou’s heartbeat. Fast, thunderous.
The sound of warm blood surging beneath the skin was deafening.

Without a second thought, he gave in.

His hot breath ghosted over Bakugou’s exposed throat, sending shivers down the blonde’s spine as he braced himself for what was coming.

Izuku pressed a few soft kisses to the skin, then ran his tongue slowly over the pulse point, savoring the heat.

Then, with a slow exhale, he extended his fangs and gently bit down.

The moment Izuku's fangs pierced Bakugou’s skin, time seemed to stop.

Bakugou’s breath caught sharply in his throat. Pain lanced through him, but it wasn’t unbearable. It lit his nerves like fire and ice all at once, nothing like the first time Izuku fed.

No... the first time had been innocent. That first moment, when Izuku had only just woken; shaking, afraid, desperate. He’d fed from Bakugou’s hand because he had to.

But this?

This was pure bloodlust.

His fingers curled instinctively into the fabric of Izuku’s blazer, gripping tightly. A strained gasp escaped his lips, then a quiet groan. The initial shock dulled into something else. something that pulsed low in his spine, warm and dizzying.

Izuku felt it too.

The instant the blood hit his tongue, his knees nearly buckled. It was nothing like the taste from a bag, nothing like the fleeting tang on his lips before. This was alive; warm, electric, intimate. It flooded his senses with every beat of Bakugou’s heart, thrumming inside him like stolen sunlight.

A quiet whimper slipped from his throat as he drank slowly, savoring the warmth, the closeness, the trust.

Bakugou clung to him, grounding himself. His breathing grew ragged, his chest rising and falling as the pain gave way to an intoxicating euphoria. 

“Shit…” Bakugou whispered hoarsely, head falling back against the stall door. “That… actually feels...really fucking good..." 

Izuku’s hands trembled against his hips, holding him steady as the instinct threatened to consume him. He didn’t want to stop. He could feel Bakugou; his pulse, his heat, his emotions, everything. Pouring into him like wildfire. 

He finally snapped, giving in as he ground his hips into Bakugou's. 

The friction satisfying the scorching heat that had become unbearable in his pants. 

"Fuck..Izu!" Bakugou cursed under his breath, feeling the hard length grind against his own. 

Izuku blushed at the nickname, hips rocking at a steady pace. 

The stall door rattled behind Bakugou's back as waves of pleasure washed over his body, bringing him closer to the edge of ecstacy. 

"Izu! If...If you keep going like that...I'm-I'm going to..cum." Bakugou's voice was hot and needy, straining with pleasure. 

Izuku gently retracted his fangs, not wanting to hurt Bakugou as his movements became erratic. 

He mouthed at the sensitive flesh, two bloody puncture wounds where his fangs had pierced. His tongue gently ghosted over the holes, skin healing over almost immediately. 

Bakugou shuddered, hot tongue melting over his skin like hot lava as Izuku sucked deep purple hickeys down his neck and shoulder. 

"H-hey..don't leave any marks." Bakugou grunted out through shaky breaths. 

Izuku chuckled lowly

Little too late.

The air became thick and hot with pants and moans as the two drew closer to the edge. 

Bang! Bang! Bang! 

The stall door rocked and rattled violently with every thrust, green tendrils of power cracked over Izuku's skin, hips rocking at a violent pace. 

Curses and moans escaped their lips, every breath becoming frantic, desperate to reach the finish. 

"...I'm-I'm gonna cum...I'm gonna cum! Fuck-Kacchan!"  Izuku squeaked out, knees nearly buckling under him. 

 "Me too...FUCK!" Bakugou's teeth clenched, as his cock twitched in his pants, ribbons of cum painting the inside of his boxers. 

Endorphins rushed through their veins; hearts hammering, breaths shaky, high from the intense orgasm. 

Izuku gave three final thrusts before slumping down to his knees, holding Bakugou in his lap as he rested his chin on his shoulder.

A soft, satisfied sigh slipped from Izuku’s lips as he leaned back, breath finally steadying. His eyes lifted to meet Bakugou’s; still wild, still intense, still watching him.

Bakugou’s gaze was heavy and unreadable, his mouth opened to say something but just as the words left his lips-

BRRRRRING!

The school bell shrieked through the silence, slicing the tension clean in half.

Izuku would have fell over like a startled goat if it hadn't been for the body still rested in his lap. 

“Tch. Right,” Bakugou muttered, rolling his eyes. His knees popped as he stood up, warmth leaving his thighs, “Forgot we were still in a damn bathroom.”

He cast a smirk down at Izuku. Face flushed to the tips of his ears, lips parted in shock, eyes back to their normal green.

“We should do this again sometime.,” Bakugou said with a wink.

Izuku sat there speechless, voice caught in his throat. 

Bakugou turned toward the stall door, all casual swagger and sharp confidence. “See ya, nerd.” With a single shove, the door creaked open and he strolled out like he hadn’t just turned Izuku’s entire world on its head.

Izuku was left alone.

Silent. Breathless.

The only sound was the thundering of his heart as he stared at the space Bakugou had just occupied.

His voice cracked the quiet like a whisper lost in a storm.

“…What the hell did I just get myself into?”
