Chapter Text
Eijirou took a deep breath as he made his way towards Midoriya’s room. He probably had taken their argument a bit too far. He knew that Kats and Midoriya had a rocky past, but the amount of time they spent alone was concerning . Anyone would question things if Midoriya ‘Clingy’ Izuku was always around their boyfriend. He just needed to get over it. Maybe if he asked, they would let him join their training sessions and then he would see that nothing was going on.
But the look in Midoriya’s eye-
Steeling himself with an apology on his tongue, EIjirou knocked on Midoriya’s door, but it swung open soundlessly. No one was in the room, but the light was on, so Eijirou assumed that he just ran down to the bathroom or something. If he just waited inside Midoriya’s room with the door open it would probably be fine. It would give him another moment to collect himself as well. He really shouldn’t have just gone after Midoriya with those accusations even if he was worried.
It had been a long time since Eijirou had been in Midoriya’s room, but it didn’t look like it had changed much between third and first year. There were a few less posters, a few more action figures and another row of those blue notebooks Midoriya always carried, but otherwise the same. During his glance around Eijirou couldn’t help but notice the mess that was Midoriya’s desk. For some reason he always pictured the other teen as a neat freak. It was kind of nice to see that the golden boy wasn’t amazing at something .
There was one notebook sitting open in the middle of it all. Probably the english assignment from today. Eijirou had been struggling with that topic in class. Maybe if he just took a quick peak. Midoriya probably wouldn’t mind, he was always willing to help people with homework, so this was basically the same. Glancing at the still open door, Eijirou crept forward and scanned his eyes over the page only to freeze.
Bakugou Katsuki, a.k.a. DynaMight, a.k.a. Kacchan
He knew it! Midoriya did have a thing for Katsuki. Fury and a bone deep sadness filled Eijirou’s stomach. To think he was about to apologise to the attempting homewrecker! With an angry bark of laughter, Eijirou scooped up the notebook and started reading. He wanted to know exactly what happened in those fucking training sessions.
Eijirou could feel the edge of the paper bending underneath his fingers, but he couldn’t find it in himself to care. The more that Eijirou read, though, the more blood drained from his face. His veins felt like ice and sweat was beading on his brow. This wasn’t a diary; it was a manual on how to cause Katsuki to break .
Fuck.
Bakugou’s quirk is called explosion. It is a heat-based quirk. He sweats a nitroglycerin-based compound that explodes once his palms warm to a specific temperature. He is extremely protective of those he cares for and holds a large inferiority complex underneath his superiority complex. To attack Bakugou you would need to hit both at once and in multiple ways.
The best method of persuasion in a sticky situation would be to first dislocate his elbows. His quirk causes a painful recoil that he wouldn’t be able to handle. Once he is pinned cut off his hands and place quirk suppressing cuffs or ropes on him. There is no evidence to support him igniting from any location other than his hands, but risks aren’t worth the possibility.
Once you have him subdued and tied down properly you can ask questions, but don’t expect a response. You have to give him the option, though, otherwise the following steps will be less effective. For Bakugou to answer anything he needs to believe that he made the decision to. He’s stubborn like that.
When he refuses to talk bring in those he cares about-
Eijirou could feel his legs giving out and quickly sat down at Midoriya’s desk. This was terrifying and was just getting worse with every word written. How many people did Midoriya have plans to hurt? Why did he have plans to hurt Kats? He knew that the past was difficult , but was it really enough to try and break him?
Start with Kirishima Eijirou. Kirishima will be easy to lure somewhere and get the drop on if you pretend to be a hurt citizen. His heart outweighs his sense most times. If need be, drug Kirishima, but DO NOT knock him out in front of Bakugou. You want Bakugou to see his eyes and hear his cries. By peeling off his skin you will both disable his quirk and cause pain. Salt water to clean away the blood with be added pain. Once the outer layer of skin is gone electricity should be enough to make him scream.
Once again ask Bakugou the questions. He might answer here, but again there is no guarantee. At this point remind him of the rising crime in Japan after All Might’s fall. Talk about when, why and how that happened. Go into detail and spare nothing. Talk about victims from Kamino Ward as well as how it could have gone better (i.e. if he had not been kidnapped). Again, request information. If that doesn’t work bring in Midoriya Izuku.
Bakugou has a complex when it comes to Midoriya. He believes himself to have failed him repeatedly based on bullying from childhood. Midoriya’s arms are his weak point and to break them in front of Bakugou will not be pleasant. Midoriya has a high pain tolerance, but you must make him scream. By the time Midoriya has passed out and Kirishima is awake again he will be willing to talk. If not repeat the previous three steps until he does.
Eijirou’s stomach churned with bile. He quickly flipped through the book and read as much as possible. Names catching on his vision and his hands shaking harder with every page. Mina, Denki, Todoroki, Sero, Aizawa, Nezu, Yamada . The names just kept going and the methods got more twisted with each entry.
Fuck, with Sero he said to use the videos of everyone before him as well as his parents!
This wasn’t just potential notes for each person, no, this was a plan . This was something that Midoriya was prepared for . A dark chuckle filled the air and had Eijirou’s head snapping upwards. Midoriya was leaning against the doorframe with a twisted little smirk on his face. It didn’t look anything like his usual sunny smile and his eyes were cold and hard. Eijirou felt the sweat that had been beading on his back slowly slip down him with a shiver. Midoriya stepped forward and closed his door with a thundering click.
Eijirou could feel his pulse resounding through his head and the room was spinning just a bit. His mouth drier than ever before. “Kirishima-kun, what are you doing in my room?” The cold twinkle in his eyes left Eijirou frozen in place. He could feel the gold embezzling on the green cover and it felt like his skin was blistering at the feeling. It was, objectively, a nice notebook if the contents weren’t so sick .
“I just-” Eijirou tried to swallow around the lump of fear in his throat. Midoriya flicked the lock on his room with a clunk and Eijirou knew nothing except that he was terrified . “Just, just wanted to t- talk.” Midoriya seemed to glide over the floor, not making a sound, until he was directly in front of Eijirou.
With a raised brow, Midoriya plucked the notebook from Eijirou’s hands and spun around toward his bookshelf. “Is that so?” Midoriya’s voice was different, calmer, more certain. In any other setting it would sound nice, but right now it just made goosebumps raise along Eijirou’s flesh. The hair on the back of his neck standing on end. Eijirou knew he wasn’t faster than Midoriya, wasn’t fast enough to escape before Midoriya caught him. “Because looking through my things is not talking, Eijirou .”
Eijirou heard his gulp ring through the silence. Midoriya began pulling specific notebooks from his shelf to reveal a safe nestled between the paper and wood. “Why did you write that stuff, Midoriya?” Toxic green eyes found Eijirou’s over his shoulder. There was a glint of something close to what Eijirou expected of Midoriya, but it was gone in an instant. The cold, blankness that had been so obvious earlier seemed to chill even further.
Midoriya twisted open the safe and Eijirou felt his soul nearly leave his body. There were nine of the green and gold journals. Next to them was a few deadly looking knives as well as pill bottles. A thick manila folder was pressed against one side. Eijirou couldn’t tell if there was more before Midoriya was clicking it closed and placing those cheap blue notebooks back onto his shelf in their proper place. “It’s always good to be prepared, Eijirou. Don’t you agree?” Eijirou felt sick .
“Midoriya, those plans are about how to torture our classmates. Our friends !” Eijirou could feel his voice raising in both pitch and volume. Fear and anger bubbling inside him, spilling out with fear drowning anything warm.
A flash of anger, a spear of violence. Eijirou saw his life flash before his eyes when Midoriya’s mouth twisted in a mockery of his smile. He wanted to puke. “I thought you didn’t want me to be friends with Kacchan, Kirishima-kun?” Eijirou’s eyes burned. He needed to warn someone. A murderer and psychopath was living with them. Had Midoriya used plans like those before? With the way he was so calm , Eijirou was inclined to believe that he had.
Swallowing, Eijirou slowly stood, his legs still wobbled and his head still spun, but he was standing. He had a slightly better chance at defending himself if need be. “I just don’t want you flirting with him, Midoriya. I- I never said you couldn’t be his friend.” Midoriya smirked again, a dark, wicked thing on such a bright face. It looked wrong in more ways than one.
“I believe your exact wording, Kirishima-kun, was ‘ Stay away from my boyfriend Midoriya. He doesn’t want you and you need to remember that ’. Or am I wrong?” Midoriya’s eyes were slightly warmer than before, but not by much. If anything, that made Eijirou’s fear triple. What had caused him to be happy in that statement?
Eijirou floundered for a moment trying to force oxygen into his lungs. The air was thin and he was dying . Except he couldn’t die here. He had to warn everyone about Midoriya. He had to make them see the type of person they were living with, that they were friends with. Stumbling backwards, Eijirou tried to force his feet to move towards the door, tried to force his way out of the room. The door swung open easily and as soon as it had Midoriya’s face took on a far too familiar innocent, teary expression. “You’re a fucking freak and I’m going to make sure everyone knows it!”
A scarred hand covered Midoriya’s mouth and Eijirou stumbled back another step, not turning around for a second. “It’s okay, Kirishima-kun. I’ll stop training with him and everything. You don’t need to worry. I just want Kacchan to be happy .” Midoriya’s voice was choked and wet. Eijirou felt bile creeping up his throat. He used to think of Midoriya as his friend . Friends don’t plot their friends' torture .
“Kiri?” Shouji’s voice rang through the hall as he stepped off the elevator. “What are you doing?” Eijirou didn’t answer. He couldn’t , not yet. Midoriya was still staring at him and he was still staring at Midoriya. “Mido, is there a problem here?” Those teary green eyes that had Eijirou’s blood running cold not even two minutes ago turned away and looked at their classmate.
“Kirishima-kun just wanted to make sure I understood what was said earlier. It’s okay, I know he’s just worried.” Shouji made a small noise of discontent and his eyes bored into Eijirou, but he didn’t look away from Midoriya as he walked backwards towards the elevator. It didn’t matter that someone else was there, none of them understood .
“He’s a fucking freak and a creep . Don’t trust him Shouji.” Eijirou’s classmate exclaimed a denial at Eijirou, but he didn’t care. Not when that manipulative psychopath was crying and making himself look so innocent. Looking as if he didn’t have plans to murder sitting in his room.
“It’s okay, Shouji-kun. I’m sure Kirishima-kun is just stressed. This- these last few years have been a lot and I understand. I heard Kacchan mention something about taking Kirishima-kun on a date, I’m sure that will help him out.” Eijirou breathed a sigh of relief as the elevator closed in front of him.
He had to warn Katsuki .
Racing down the hall as soon as the doors opened, Eijirou pounded on his boyfriend’s door. He knew he sounded frantic, but he was . He needed to get that creep out of here. He didn’t trust Midoriya not to use those plans. The door was yanked open and the snarl that had been on Katsuki’s face melted away in an instant, ushering Eijirou into his room. “Ei? What’s fucking wrong?” Katsuki’s voice was gruff and warm and everything Eijirou needed after the chilling cold terror of Midoriya.
“Kats, Kats it’s about Midoriya.” Those gorgeous red eyes flashed with something and his mouth set into a slightly harsher line. “Listen, I went by his dorm to apologise because I know I shouldn’t have blown up on him, okay? I trust you and that should be enough, but when I was there I saw this notebook .” Eijirou’s breath was coming in pants and his knees shook violently. Cut off his hands.
“Ei, calm down. You need to fucking breathe slow. Sit the fuck down, okay?” Tight worry filled the air as rough, callused hands led Eijirou to sit at Katsuki’s desk. So incredibly similar to Midoriya’s, but different . Different because this was Katsuki. Katsuki who Eijirou loved. Katsuki who was sane and loud and always said what he meant and never lied. “Breathe, Shitty Hair. Breathe for me.” Stuttering breathes and pants filled the air as Katsuki’s hand rose and fell in a steady rhythm. It took a few minutes, but Eijirou could finally see, could finally think.
“Kats, he had plans . Plans to hurt all of us. Torture , Kats. It’s terrifying .” Katsuki’s eyes widened slightly before falling into a soft sort of acceptance. “Katsuki he could kill us all.” Eijirou knew his voice was shaking again. He could feel the wetness on his cheeks from falling tears. He knew all of this, but none of it mattered because Katsuki needed to know. He needed to understand.
“Ei, Deku couldn’t even kill the fly in the kitchen this morning. I’m sure it was nothing.” Eijirou felt his heart cracking. Katsuki’s eyes were set and his mouth twisted in a way that Eijirou recognized as fear and confusion.
Katsuki didn’t believe him.
“Katsuki, listen it’s bad . He- he wrote about how to break you .” Eijirou opened his mouth to continue, but didn’t get that far. Katsuki wrapped him in a hug and whispered soothing sounds in his ear. It wasn’t often that Katsuki was comforting, only when Eijirou was panicking and spiralling.
“Ei, I’m sure it wasn’t that bad. This is Deku . It’s fine. It’ll all be fine.” Katsuki’s words didn’t match the slight waver in his tone. Most wouldn’t notice, but Eijirou did. He noticed and knew what it meant.
Katsuki was afraid of Midoriya.
