Chapter Text
A monster stalked the hall of Aldeara High School. Standing at seven and a half feet tall, this monster let out an aura to all nearby her- cross her, and die. The belly of the monster was ravenous, and capable of devouring anything in her path. Her claws were sharp enough to pierce concrete. Her tail was able to impale a body through with minimal effort. Her teeth were sharp enough to sheer steel apart. And her eyes… when they were visible, they were a poisonous green. The same color of her blood, which could eat through the most reinforced steel. Of course, to see her bleed, you’d have to go through her chitin. No one had really tried to pierce it, but they all heard stories. It could shrug off the most powerful explosions of the most popular student- Bakugou Katsumi- with not even a scar. She could be thrown through walls, and not a single scratch would appear on her. Truly, a dangerous beast. And the mind within was one of the smartest in her area. Calculating. Able to track prey or to solve anything thrown at it. The students and even most teachers were utterly terrified of her.
Monster. Beast. Soon-to-be-villain. Those were the words whispered by those around her. Katsumi was seen as brave for even being able to be crass to the monster, and never backing down when she looked down at the one without the non-mutant Quirk.
Said monster had just gone to her locker, and had accidentally ripped it from its hinges, like a normal man would rip toilet paper apart. The scream of metal sent flinches down the spines of most nearby. All save Bakugou Katsumi. She stared down the beast, which turned to face her.
Bakugou was built like a brick shithouse. She had been training to go to UA University to become a Hero. Many said that the two would be enemies within half a decade. That she was watching the one she knew would be her greatest foe.
The beast trembled, shivers coming out of her as she beheld the broken locker door. Her fists clenched, turning the metal into a ball. Bakugou stepped closer.
The beast stepped back, tail lashing around her leg.
Then Bakugou finally spoke.
“‘Zumi… just breathe.” Katsumi approached the beast, and laid a hand on the chitin. “It’s okay. It’s okay.”
Ragged gasps came from the beast.
“That’s it. In. Out. In. Out.” Katsumi instructed. Her hand remained on the chitin. Finally, the gasps became full breaths in and out. “It’s all right. It’s fine. You’re fine.”
The head of the beast turned towards the Blonde bombshell. “T-thanks, Kacchan,” a rather surprisingly feminine voice squeaked out. It sounded so wrong- the sound of a teenage girl coming from the mouth of the perfect killing machine. “I… I didn’t-”
“Yeah, I know,” Katsumi told her best friend. “You didn’t mean to… must’ve pulled to much, huh?”
“Y-yeah…” The beast’s head whipped from side to side, eyes covered by a transparent chitinous lens. The beast never needed to blink because of that. “I scared them again…”
“Fuck ‘em,” Katsumi told her, patting the chitin. “‘Sides, we got class soon. Get your shit. No one’s gonna steal from your locker.” The beast picked up her books, holding many in her hands, while wrapping her tail around a backpack.

Writing was hard for her. It’s not that she was dumb. Far from it, in fact. The hard part came from her habit of accidentally breaking pens and pencils. So she wrote slightly more slowly then most so that she didn’t end up breaking them. Her tail whipped back and forth behind her as she mumbled. She was writing in her notebooks- Hero Analysis. She had covered the name up.
That was learned knowledge. When the girl with the murder machine quirk talked about a Hero’s Quirk, people tended to think she was planning on how to beat them.
Someone had tried to fight her once over that.
Once.
Her stomach growled, much to her embarrassment. She couldn’t help but hear the gasps of the people around her. The uptick of fear.
Tears slid out from the chitin that covered her face. Her tail coiled around her legs. It did that when she was upset.
It was around her legs a lot.
She went back to her notes about Fat Gum at this point. She lost herself in the notetaking, drowning out the sense of fear she was feeling from the others. Drowning out the whispers.
“Monster.”
“Freak.”
“Villain in the Making.”
“Abomination.”
“Horror.”
Those words, and more, had nearly devoured her. Ever since she had grown the chitin. Katsumi had thought she was badass. Everyone else thought she was a freak.
Her mom had always tried to be nice… but she still flinched from time to time. She still showed fear, when she was in the darkness, her eyes peering out at her.
She could smell it.
Katsumi almost never felt fear. She was the only one that didn’t feel it at least once a week. It’s why she followed her. Katsumi would be a Hero. She wanted to be one, too.
To save people.
To turn this horrifying form into something that brought relief to others.
And if that failed?
Well, hopefully Katsumi could take her on as a sidekick or secretary.
Or she could be a housewife for her.
That thought changed her thoughts rapidly. The two were closer then most realized. They weren’t just friends. Not anymore.
Oh, they hadn’t fucked or anything. But they’d kissed. Katsumi had promised her, that no matter what, she’d be there for her. No matter what happened.
Izumi shifted in her seat a little at thinking at that kiss.
*****
Katsumi couldn’t help but watch Izumi. She saw Izumi shift a little, a slight blush on her cheeks. She was probably thinking of that kiss.
‘That damn nerd,’ she thought to herself. ‘Oh, she’s so scary and unstoppable. HA! Just have me kiss her and she falls apart!’ she chuckled to herself.
Not that she was much better. That kiss had only solidified her position on Izumi.
The nerd didn’t have a mean bone in her body- at least not at first. Katsumi knew that years of being shat on by society changed someone. If Izumi hadn’t been so damn kind, and still trying to be so damned kind, then she imagined that the nerd would’ve already committed a murder.
And she’d help hide the body.
A Hero is always prepared. She had bought a shovel, just in case. That, and a secret second costume.
A villainess’ costume.
If the Nerd had to go down that dark path… she wouldn’t let her go alone. It wasn’t that she believed it’d happen. But… even she had had dreams of it as University approached.
They weren’t nightmares.
You didn’t wake from nightmares moaning for her to come back and keep filling you.
In this world, there were no longer just men and women. What had been two was now three- men, women, and futas. If the censuses were right, the world was approximately 60% female, 30% male, and 10% futa.
The changes had many wondering if this would be a long-term change- if the count would shift. Would hermaphrodites like Izumi be the only gender after a few generations? Would futas die off? Would men die off? Science still hadn’t figured that part out. It did mean that suddenly, there was competition for men. Men were no longer seen as expendable. It had done wonders for men’s mental health. But that’s besides the point.
Katsumi was female. Izumi was a futanari. So in those dreams, Izumi had filled her, ruining her and making her into a broodspawn.
It was probably the alien look of her appearance, but she tended to imagine herself as a broodmother, or property. She thought she hid her sub side well. At least, no one commented on it. And it wasn’t like she’d be a sub to anyone BUT Izumi.
Where was she going with this again? Ah, right. Career notes. She’d put down ‘Hero’ with ease. She was sure that most of the other extras were doing that as number one. Who didn’t want to be a Hero? Able to use your Quirks for fame and fortune. Oh, sure, most didn’t even make it to the Hero Universities, and even fewer made more money then the average salarywoman, but that was the goal. To reach the top.
To be the next All Might.
The Hero Industry wasn’t super biased against men. In fact, the hottest guys usually got high up on looks.
Katsumi was pretty sure that half of All Might’s money came from porn rags about him. And he wasn’t the only one, either. Tiger was pretty popular. Sure, there were jokes about him being the only member of the Pussycats who didn’t have one, but that just lead to harem porn out the wazoo.
Had she read any of that? A bit. Though harems usually made her imagine being bred alongside a row of obedient fuckslaves by Izumi. Oh, she’s was getting turned on and tuning out everything. Again.
Fuck.
Katsumi slapped herself slightly to get herself re-focused. She finished with her secondary, tertiary, and so on careers. She did add ‘Housewife’ as the fourth option- she figured she’d get Heroics or something hero-adjacent, but there wasn’t anything wrong with house-wifing. She shook her thoughts away as the teacher collected the papers, nodding, though she paused at her fourth option.
“Are you sure, Bakugou? That seems like a waste…”
“I’ll be a Hero,” Katsumi snorted. “Good to have a plan B.” She rolled her eyes as the teacher began to collect the ones in the back. Then she got to the no-go zone.
Desks had been pushed away from Izumi, who was hunched over her desk. Those that would have been near her had been pushed to touching the ones in the other direction.
Katsumi cursed that her assigned seat was so far away. She wasn’t sure if it was the ass-kissing principal trying to keep her ‘safe’ from the ‘school’s soon-to-be embarrassment’ or genuinely afraid the two would come to blows in class or some shit. The walk over had Izumi’s head turn up to look at him. A sound in her throat that Katsumi knew was an inquiring sound came out, but it made the teacher shudder. To be fair, anything but Izumi’s voice was utterly fucking terrifying. It was just that she wasn’t afraid of her anymore.
“M-Midoriya-chan… p-please give me the paper…” she stammered. Izumi’s tail swished, and her removed her claws from the paper. The teacher grabbed it rapidly, not looking at it in her hurry to get out of her ‘range’.
Izumi’s tail was prehensile, and had quite the range. She’d never hurt anyone with it on purpose, but accidents did occur. She put her claws on the wood, accidentally denting them with minimal pressure, and watched her scamper back.
“N-now then…” since Izumi’s paper was on the top, she froze, eyes wide.
Katsumi’s eye began to twitch. ‘Don’t do it, bitch. Don’t fucking do it…’
“I-is this some form of JOKE?!” she hissed, hands shaking with rage, locking eyes with Izumi. Said individual let out an audible whimper and tried to shrink into herself. She was flexible to do that to at least some extent.
“W-what did she write?” one of the extras asked. “Villain? Serial killer?”
“My money’s on murderer!”
“Bank robber!”
“Rapist!”
“Super Villain!”
“All Might’s killer!”
At that, Katsumi let out a blast that made her arm ache, snarling.
“ALL RIGHT, WHO THE FUCK SAID THAT?!” she bellowed. “WHAT KIND OF LIMPDICKED, COCKSUCKING CUNT SAID THAT!?” Her eyes scanned around, promising murder.
The students pointed to another of the futas in class.
“All right, dickgirl, let me tell you something real good,” Katsumi hissed. “‘Zumi? She’s a fan of All Might. Big fan. Isn’t that right?” Izumi nodded meekly. She knew better then to try to get her to stop when someone implied she’d hurt All Might. “So you guessing that she’d write that her career goal was to put the Symbol of Peace in the ground rubs me the wrong way. And that makes me angry.” She let out a few more blasts, now having one leg on the desk behind her, one still on her chair. “And when I get angry, I get violent. You know what explosions do to cunts like you? Wanna get your dick sheared off?” The other futa shook her head rapidly. “Then shut. The fuck. Up.” She slid back into her seat.
“Hero.”
“Pardon?” Katsumi asked. “You callin’ me a hero?” She saw Izumi’s tail coiled around the chair- thankfully not causing the metal to dent.
“She wrote Hero.”
“Hey, that shit’s private,” Katsumi growled. “And I’d bet a hundred yen that we all wrote that. What’s the fuckin’ problem?” The teacher just motioned to Izumi. “What’s the fuckin’ problem?” she repeated.
“Are you hoping for some ‘fellow apprentice that turned to evil’ thing?” one of the students asked.
The classroom needed a new window. Thankfully, that student landed in the fountain.
