Kasumi, the Blond Bombshell with a short fuse.

Izuku looked at the snarling blond in front of him as the door locked behind them with a slightly detached nervousness. He wasn't scared of her hurting him, though that was certainly a thing she would probably try given the chance.

_I really want to know what's going through Nemuri's mind. She knows Kasumi hates me, absolutely loathes my existence. Izuku wondered, watching as Bakugo Kasumi sat down in one of the chairs, pointedly ignoring him for the moment as she searched the room. It's probably one of her ways of trying to get me to squirm... but there aren't any cameras as far as I can tell. That makes sense, these are supposed to be sealed off unless a panic button is hit. So she can't be getting a video out of it. So why?_

"Oi, Deku!" Kasumi barked out, fuming in her seat. "Midnight may have locked us in here expecting us to get naked, but if you think I'm going to just start stripping you're dumber than I thought."

"No, Kacchan." Izuku used their old childhood nicknames out of habit, ignoring how it made the girl flip him off. "I didn't expect this either." Which was the absolute truth. Nemuri rarely ever discussed school related things with him except what she'd already taught. Maybe that'd change in the future, but for now he had no idea what the dominatrix heroine was planning to teach them. "I figured if I so much as took off a shoe, you'd try to roast my face again."

"Damn straight I would." Kasumi huffed, slouching in her chair. "Damn slut teacher, damn pervert principal. Anyone who gets taken out because they can't keep it in their pants is a fucking idiot and should quit trying to be a hero."

"That's a little harsh, Kacchan." Izuku took his seat, about three feet from his old, former friend. "We're teens, students and human. Someone's gonna do something stupid. And while this is kinda sudden, I can't say it's wrong of them to try this kinda method."

"It's a stupid method!" Katsuki roared, pointing at Izuku as sparks flew from her palms. "Why don't they do some stupid psychological shit like try to overload people on porn or something! At least those people want to be seen fucking naked!"

"That's actually a good question..." Izuku gave her that win. "Maybe it's because there's no human element in porn? They can't react in real time, and there's no sense of danger, so they don't learn to not drop their guard, thus defeating the purpose of this training?"

It was silent for a little while longer, except for the tiny crackles of sparks and miniature explosions as Kasumi mulled over her thoughts, not really looking at him.

Izuku took the time to look around the room himself. There was a table against the wall, and the two chairs they were sitting in, still fully clothed. The panic buttons were bright yellow in an otherwise grey room. There was a tile floor under foot, with rugs bunched up in a corner of the surprisingly large room.

"It's still a fucking stupid method of training to not fuck up if you see a tit or dick or something." Kasumi finally grumbled, fuming mad at her predicament.

"Hey, at least there's not anything trying to strip us, right?" Izuku tried to joke, but remembered which school he was at. They totally might have that hidden away in the walls.

"Bet you'd like that, huh?" The bombshell snorted.

"Kacchan..." Izuku actually felt that one. That one actually hurt him on some level. "Do you really think that little of me? In all the years we've known each other, have I ever once done anything that would make me seem like that type of person?"

"I don't know, you tell me, Deku." Kasumi gave a glare of such anger, Izuku wondered if she'd suddenly start shooting explosions from her eyes. "If you're willing to lie about your quirk, even after all these years, then I don't really fucking know you, do I? Because apparently, you're not that lame ass cowardly piece of shit Deku without a quirk who always acted high and mighty!" Kasumi launched out of her chair, throwing a punch at his face.

Izuku, after many sparring session with the variety of Heroines, reacted quickly, falling from his chair in a sideways roll, jumping to his feet and away as Kasumi detonated his chair into metal shrapnel at the door. "I thought I told you, Kacchan! I never lied about my quirk, I didn't even know I had one for the longest time!" Izuku yelled, dodging another leap, the edge of the explosion singeing his cloths a bit. "I couldn't have known!"

"Stop lying, Deku!" She snarled at him, holding her hands up and at the ready, uncaring that she'd torn her skirt or burned part of her top off in the initial attack. "You can't get that good at using a quirk you haven't had for a year!"

"Kasumi, I'm not good at using my quirk!" Izuku held up his hands at her. "I still hurt myself using it, but because of its nature I also heal really quickly!"

"Bullshit!" Kasumi lunged again, launching herself with twin blasts of her nitroglycerin sweat behind her to try and kick at Izuku, who once again rolled to the side, grabbing the chair Kasumi had sat in and brandishing it before himself. "Your quirk is super strength, but it also heals you? That's two mutations considering neither of your parents have those quirks, quirk mutations don't work like that! YOU'RE STILL LYING DEKU!"

With that yell, Kasumi charged at him, throwing explosive punch left and right as Izuku could only lean out of the way to dodge, keeping the chair between himself and the furious girl he'd been locked in a room with.

Crap, that heat's gonna set my clothing on fire soon at this rate! And I don't think being set on fire will make Kasumi stop with how mad she is! Should I just tell her? That's a big leap though, and she's not willing to listen right now anyway. C'mon, Izuku, think!

"Quit trying to run, Deku! We're stuck in this room until they let us out!" Kasumi yelled at him as he dropped the chair, using Incubus Fuel and One for All to jump around the room as she kept running at him, not willing to let him rest for a single moment.

"Kacchan, you need to stop!" Izuku yelled. "This will turn out better if we just talk!"

"You'd probably just lie again, you green haired fuck!"

"I've never lied to you, Kasumi!" Izuku yelled. "Just stop attacking, and I'll try to explain as best I can!"

"Your best isn't good enough!"

Well, talking wasn't going to work like this. Izuku felt his bones creak the tiniest bit as he pushed off once more, this time at a more awkward angle as he bounced three times in rapid succession to get behind his childhood bully. Wrapping his arms her shoulders, Izuku grabbed his left wrist with his right hand and pulled it tight to her chest. As soon as one foot was firmly on the ground, Izuku swept the girl's legs out from her, releasing One for All as he did to not break her legs.

"Get the fuck off me, Deku!" Kasumi yelled, grabbing at his wrists and burning them with explosions even as she lost stable ground.

Izuku ignored her and the explosions, used to worse during his own training and letting Incubus Fuel heal the wounds as fast as she could give them to him, pulling sharply to the right as he brought his hand up and back over the shoulder to grab the scapula.

"You really wanna die that badly?" Kasumi abandoned burning his wrists, aiming one hand up at his face and another down at his feet as best she could, letting off explosions that were hot, loud and with as much **** as she could muster.

His head was ringing and his knee felt like a horse had kicked it, but Izuku kept going, pulling his arm tight around her neck while he had the chance. With her not attacking his hands, he was able to form a clamp that met at his wrists, one arm going down her back as the other kept itself under her chin.

Kasumi went to yell at him again, probably telling him to let her go, but Izuku already pushed down with his left arm, bringing it in as tight as he could to her body before bringing it back up into her throat once more. Whatever she planned to say was cut off into a **** of rage as her hands flew to try and grab his arm.

Izuku took a moment to breath a sigh of relief, just a moment. He wasn't sure a Rear Naked **** would actually work on her, given she had the same smooth skin as her mother. That could have easily failed, but it was the first thought he had for a hold that would get her to listen. Maybe not the best, if his ear and knee could give their opinions, but in the end it turned out fine. "Okay, Kacchan. I want to talk things out with you, but you need to listen, okay? I'm going to release the hold a bit, slowly. If you try to attack me, I'll lock up, hold this position until you pass out and hit the panic button. I really don't want to fight, okay? So just listen, for once, please."

Kasumi still struggled for a moment longer, her face turning red as the lack of oxygen started to affect her before she finally went limp, tapping Izuku's arm.

Izuku did as promised, letting the hold go enough so that Kasumi could breathe again, if with difficulty. She took as much air as she could in, and Izuku could imagine the scowl on her face as she gave a few wet coughs.

"Fine..." She growled as much as she could, the vibrations being so powerful that Izuku's chest was feeling the rumbling. Maybe it also had to do with him clutching her to his chest for dear life, because he really didn't want another fight on his hands. "Let me go... and start... talking..."

"Promise not to attack me again?" Izuku asked.

"Maybe... if you're not... lying..."

"Well, that's as good as I can ask from you, Kacchan..." Izuku muttered, rolling his eyes a bit. "Could you at least drape a rug around yourself? You wrecked a good portion of your uniform."

"No." She managed to get 'Stop stalling' across in that one word.

Izuku rolled his eyes again, but finally let her go. She fell to the floor coughing up excess spit, glaring up at izuku as he moved to grab the chair and put behind her. He pointedly stopped looking at her as soon as he could, focusing more on gauging the damage to his own uniform.

The back's really dried out, I can feel a breeze on my triceps. Probably got dried out and then cracked from the heat of the explosions. The knee on my left pant leg is scorched to hell... I'm gonna need a whole new uniform. Izuku sighed, going past his uniform and feeling himself for any lasting injuries which, due to Incubus Fuel, would probably be more akin to lost hair.

Eyebrows? Check. Hair? Maybe a little dry, but not too bad. Ear feels good as new too, so there's that at least.

"You can fucking look, you pansy." Kasumi barked out. "You could have had the chance to do whatever and you didn't take it. At least you're not subhuman garbage."

"Gee, thanks." Izuku rolled his eyes as he turned around, seeing Kasumi sitting in the chair, legs and arms both crossed as she glared **** at him once again. Her outfit was wrecked, with her top barely counting as a bra, more of a toga from how only one side was still there, hanging onto her shoulder and ending just below the curve of her breasts. Her skirt, likewise was gone, though it had fallen off entirely in the struggle. Small cuts from the shrapnel of the chair littered her body, and her underwear were on full display. Though she didn't let that bother her in the slightest, like almost anything else that would hamper her in reaching for her goal of being the number one hero, better than All Might. "So... where to begin..."

"Maybe you should start with telling me what the fuck your quirk actually is." Kasumi seethed.

"I guess that works, kinda." Izuku sighed, rubbing the back of his head. "See, the thing about my quirk is that it IS super strength, and regeneration... and a few more things, besides. But it needs a power source. So, I guess you could say my quirk is more of a stockpile-type quirk, the less heard of fourth type of quirk."

"Yeah yeah, I know all about them, I'm not a fucking idiot like most of these side characters. I actually study, you know."

"Right, right. I know that." Izuku placated her. "You've never done anything without giving it your all, even homework. You're just that type of person..."

"Quit trying to suck up, it's only going to make me madder!" She roared at him. If there was a slight dusting of red on her cheeks, it's because of the **** hold!

"Right..." Izuku paced a bit, running his hand through his hair repeatedly. "I'm just not sure if I should tell you what the power source is. It's kinda private, and it relates to how I found out I had it in a round about way. It's something I can't just tell people, it's so private. Only a few people know about it..." Okay, 'a few' was stretching the truth. Literally most everybody he interacted with knew about it, but only because they were part of the reason he found out about his quirk and can even use it.

Izuku turned to Kasumi, his eyes burning with absolute dead seriousness. "Kasumi, if you want to know, I need to to promise me that what I tell you cannot go beyond this room." He told her, slowly turning to face her.

"Yeah, yeah. Sure, I won't talk to anyone about it." Kasumi said, trying to wave him on.

But Izuku wasn't having it. He stepped up, hands clenched into fists and his teeth grit in a scowl. "No." He stood above her, seeming larger than he was in all actuality as he bored into her soul with his eyes. "This is serious enough to need you to actually promise me. Promise me that you won't even breathe a word of this outside this room without my say so, and only to people that I approve you talking to about it. You need to promise me that, on everything that you stand for, on your dream even, that if I tell you what my quirks are, you do not tell a single soul anything."

Kasumi looked at Deku, really looked at him for the first time since they entered that room. She saw how serious he was, like the one time he finally stood up to her when she learned that he would, in fact, be attending UA and had confronted him on the grounds of Aldera High, in an alcove off to the side of the main grounds.

I'll become a hero, Kacchan. Not even you can stop me!

Somehow, Kasumi's scowl grew three magnitudes deeper. "Fine, you shitty nerd. I promise that no one you don't tell me I can talk to about it will learn your secret from me. If I do..." Kasumi hesitated for the briefest of moments before gritting her teeth. "If I do tell anyone who you don't let me tell, I'll... quit UA and give up being a hero." She bit out, turning her head away.

"K-Kasumi!" Izuku was not expecting that bold of a promise. He just wanted her to take the matter seriously! To stake her entire dream on this promise... well, that was something Kasumi would never take lightly. She absolutely meant what she said.

"Listen, you fucking Deku." Kasumi started back up quickly. "If I can't even keep a shitty little secret like whatever yours is, I don't deserve to be a hero. What kind of hero can't keep what's supposed to be classified information classified? BUT!" She snarled at him, her hands smoking once more as she pointed at him again. "If I find out you're lying to me, I'll fucking kill you on the spot. Do I make myself clear?"

"Crystal, Kacchan." Izuku couldn't help but find himself smiling a bit at her for a moment. That was all he had before the gravity of the situation hit him like... well, a lot of different things. He had a lot of experience with taking hits, after all. "Okay, just give me a second to prep for this. It's... it's a big thing."

"Stop stalling and spit it out, or the promise is off, Deku."

"Fine..." Izuku took a deep breath, tensing his legs ready to start jumping around again. "Myquirkrunsoffsex!"

The silence was suffocating for an entire minute.

"Ex-fucking-cuse me?" Kasumi cleaned out her ears, her face twitching in barely contained rage as she cleaned out an ear. "Did you say what I just think you fucking said?"

"My quirk... It basically runs off sex..." Izuku sighed, putting his face in one hand. "It's a little more complicated than that, but that's the most basic of basic explanations of it."

"you gotta be shitting me... THAT'S what you're going with?" Kasumi yelled, standing up and stomping over. "That is the stupidest, most perverted thing I have ever had to hear, and we're class mates with the god damn grapist! He can't keep his fantasies to himself if you duct-taped his mouth and used him as shark bait! I'm gonna fucking KILL YOU!"

"Wait!" Izuku threw up one hand to hold off the incoming fist, the other digging into his pocket for his wallet. "I have my ID here with my quirk on it! Government proof that I'm not lying!"

Kasumi paused mid swing, face twitching between incredulity and curiosity. Was the nerd fucking serious? Could such a thing actually be true?

Swiping the wallet out of Izuku's hand Kasumi flipped it open and began scanning the ID. She looked it over many multiple times, looking for any sign that it was a fake, a fraud that the idiot somehow managed to get made.

But no, there it was. Plain as day.

Name: Izuku Midoriya

Quirk: Stress Eater

"Stress Eater?" Kasumi wondered aloud, rolling both the thought of Deku actually having a legit quirk and the fact that it may, in fact, have something to do with sex. "What the fuck does that mean?"

"It means," Izuku didn't bother trying to take his wallet back at the moment, as the ash blonde girl was still looking over it with an iron grip. "That my quirk takes stress, and turns it into power. Namely through sex, and trust me Kacchan, I've tried figuring out how to use it in other ways."

Kasumi was silent, eyes darting around as her thoughts sped up. "I want to know everything, Deku. What the fuck is your quirk, how the fuck it works, how in the fuck you figured out it was god damned sex that activates it... and why, above all things, do you have the ID of a government employee?"

Crap, she noticed that... I guess it doesn't matter, I'd have to tell her about it anyway... and she'd learn about it in her third year of hero school anyway, and she'd kill me then even if this didn't happen, Were Izuku's thoughts as he sat on the ground with a heavy sigh.

"Well... You remember that day, with the slime villain?" Izuku cautiously ventured.

"Mention him again and I'll break your fucking nose, Deku." Kasumi scowled.

"Okay, okay. Sorry. It's the day we both met All Might, too, if you wanna remember that." Izuku smiled. "Boy, that sure was a heck of a day, wasn't it? It seems so far away now. After that whole thing, and just after you ran after me telling me you didn't need my help-"

"Which I fucking didn't." Kasumi protested.

"After that, All Might came to find me. For some reason, he was so impressed by the fact I tried to rescue you where the rest of the pros did nothing while he... couldn't at the moment, that he wanted to see if I had the stuff to be a hero, even without a quirk. So, he began training me." Izuku braced for the inevitable.

"All Might! Trained you?" Kasumi barked out a laugh. "What a fucking joke. I can just go up and ask him if you're lying, you know that, right?"

"Go ahead. He'll tell you the truth. In fact, tell him, 'Izuku wants to share his All American Dream Workout Plan with me' and he'll tell you the truth for certain." Izuku trusted the man would get the hint... maybe he should send a text later. "Anyway, so we trained for a few months when... well, it happened."

"It? What is 'It?' Don't start getting all ambiguous on me now, nerd!"

"Well, I guess you could say I got a job... and laid. And I got laid because of my job. My job is to get laid..." Izuku trailed off, watching Kasumi's face as she just... looked at him.

"Deku, are you being pimped out by fucking All Might of all people?" Kasumi had to question, because that was the only thing she was getting from his vague as hell explanation.

"What?" No, no no nonononononononono no. No." Izuku waved his arms at the girl. "All Might's not pimping me out! The... The government is, kinda."

"What."

That's all Kasumi could say. Her jaw was moving, but no sound was coming out. Her eyes were pinpricks, her teeth gnashing together every time her mouth shut. Her arms were shaking in rage.

"What."

"Yeah, I get that feeling. I still don't understand why, but apparently I'm now the internationally approved stud for heroines. Made me sign a contract and everything. It's apparently a legal thing they can do." Izuku shrugged a bit. "Don't ask me how they decided I was the right fit. Maybe because All Might trained me, and he was a Stud too during his time in America?"

"What."

"But, either way, some heroine who I will not name decided that she wanted to use my services." Izuku shook his head. "And then another, and another and another. And that's how I learned about my quirk."

"Wha-" kasumi smacked herself in the face, getting her mental faculties back in working order. "Why the fuck would anyone want to fuck you of all people?"

"Because it was my job?" Izuku shrugged. "The way it was explained to me was that my job was to provide no-strings attached sexual relief, as well as giving the heroines at least a semblance of having a significant other. And, as a stud, if they got pregnant, they'd be taken care of for the duration of the pregnancy. But it turns out my quirk was perfect for my job."

Izuku stood and quickly began pacing. "See, My quirk works by draining energy from people I'm having sex with. I'm still not sure of all the mechanics behind it, but so long as I have a part of my body inside them in any way that can be considered sexual, I can drain stamina and stress, and things that are tangential to them such as Anger or sadness. Then, my quirk releases endorphins that are around three times as powerful as the endorphins released during sex, but somehow bypass any form of tolerance buildup. Anything I drain is converted into pure energy, which my quirk stores. The conversion rate is nearly perfect, and heroines have a lot of stress and Stamina both." Izuku tried to laugh, but the unusual stare from Kasumi made it die in his throat.

"Anyway, after that, I can use that energy to do... well, a lot of things. I can use it to augment my ability to heal, my strength or speed, my durability, even my reaction times if I focus hard enough! I don't really need to sleep anymore, and I couldn't if I wanted to anyway. Way too much energy, and I can't shut it down completely. Not yet, at least. But I'm trying still."

Kasumi was still staring at him, her jaw clenched shut.

"And if you don't believe me, you can ask... pretty much any female hero or sidekick." Izuku blushed a bit. He really didn't like saying it like this, but needs must and all that. "I've been in very high demand since I started. If they don't know me personally, they know OF me... and are probably waiting for their turn."

Kasumi was silent even now. It was honestly worrying Izuku. Did her mind break like his mother's had? That... that would be hard to explain to everyone. "Um, Kasumi? Are... are you okay?"

"Huh?" Whatever funk Kasumi was stuck in was broken as she came back to herself rapidly, rubbing her face. "I'm... I'm fucking fine, you stupid nerd. You really expect me to believe that crock of shit?"

"Look on the back of my ID." Was all Izuku had to say, gesturing to the wallet the girl was still holding.

Kasumi did as told without any comment, which was really off putting. Normally, the girl would at least yell at him for "Telling her what to do" or something, but here she seemed to be almost lost, in a trance or something. She looked at the back, scanning the card once more.

SPECIAL IDENTIFICATION

IZUKU MIDORIYA

INTERNATIONAL HEROINE STUD

GOVERNMENT APPROVED UNANIMOUSLY ACROSS THE WORLD

Silently, the girl put the card back, looking at it like she didn't understand anything.

"Normally, they tell the heroine students in their last year of school about the Stud Service, but you're an exception I guess. Sorry to have to drop this all on you like this, Kasumi. And that's not even all of it, but I don't think you can handle any more for the time being." Izuku reached over as he paced by, snagging his wallet from the nearly nude girl.

Kasumi just sat there, staring at the floor for a while, her eyes darting around but never really lifting. Izuku was getting really worried when, after the ten minute mark she hadn't said anything when she suddenly jolted back to life.

"Man, this is some stupid fucking shit." Kasumi tried to growl, but it sounded rather weak. "You're trying to tell me, that you are an international human fucktoy for heroines?"

"Uh, yes?" Izuku answered. "Like I said, I don't know why I was picked either. It can't have been for my quirk, since I didn't know I had one at the time."

"And your quirk... your damn quirk that you didn't know you had was perfect for the damn job of being an international human fucktoy."

"Yeah, that too." Izuku shrugged. "How was I supposed to figure that out when I was a kid?"

"And you were trained by All Might himself?"

"Also yes." Izuku answered. "Look, Kasumi, I know it sounds insane, but you gotta believe me. You know I've never been good at lying. We've known each other since we were a year old, each."

"Yeah, you always were a shitty little Deku. Always crying, always trying to stand up to me, always quirkless. Tch..." Kasumi looked away, crossing her arms once again under her chest. "Fine, so I believe you. Still a Deku, I guess."

"Really?" Izuku sighed in relief. "Thanks, Kacchan. I really do appreciate it."

"Does your job also cover heroine students?"

It was Izuku's turn to have his mind blank in surprise.

"Oi! I asked you a fucking question, Deku!" Kasumi yelled at him, red spreading across her body. "Does your job include taking care of Heroine students?"

"Uh... Yeah, why?" Izuku asked, feeling his throat dry.

"Why the fuck do you think, Deku." She responded with a flat glare. "I'm pretty fucking stressed after hearing all that shit. Might as well make use of this stupid useless lesson if I can."
