Chapter 3: Combat

Izuku woke up with Katsumi wrapped around him, sleepily nuzzling into him with an uncharacteristically soft smile on her face.

"Hey Kacchan. Are you awake?" Izuku asked, tickling her sides with his Quirk.

"Hehe yes! Stop tickling ME!" She loudly giggled and lightly slapped his arm, causing Izuku to chuckle. It was good to see her this way and not the normal 'Angry pomeranian' mode.

Izuku stopped with his improvised torture and simply laid on top of her, restricting her breathing slightly as he kissed her neck softly. "That's my good toy." He said with a low voice while pressing his thigh to her warm, wet core.

"I-Izuuuuuuu! P-Please don't tease me!" Katsumi whined and whimpered as Izuku smirked into her neck. "I-I need it! Please? I'll be a good toy, I promise!"

"Awe, but you're already being a good toy, so that isn't really a bargaining chip for you at this point. What else could you possibly offer me?" Izuku asked teasingly before dragging his teeth down over her exposed nipple and made her buck her hips, which pressed his throbbing cock against her soaked pussy. "Did I say you were allowed to move?" He growled, making her 'condition' worse as he ran his tongue across her jugular. "Did you know that you taste very sweet? Must be part of your Quirk. I wonder how sweet certain… other places would taste."

Katsumi moaned pathetically as he suggested that, but then simply kissed her pouting lips and held her close to him, both laying naked in the early morning light.

And that's when a naked blonde girl ran through his wall, tripped over his bed, and landed with her face inches away from his dick.

"Oh, sorry about that! Hey! You're a guy, aren't ya?" The older girl asked, shamelessly glancing between his face and dick with an unwavering smile.

"Oi! Quit looking at his dick!" Katsumi shouted, sitting up and pushing the girl away, only for Izuku's door to open and reveal another two girls while Izuku pulled on underwear.

The first girl had shoulder length blond hair and blue eyes with a cute, if not simple, face, a larger bust then Katsumi and a muscular build. Izuku could immediately tell that Katsumi was definitely jealous.

The second girl had long Periwinkle hair that seemed to be wrapped around her like a coat, and again like the naked one her bust was nothing to sneeze at, but unlike the first girl she was giggling and reprimanding the first girl. "Miria you can't just phase into a first year's dorm like that!!!"

"Hey…guys…can..can we j…j…just… go." The third one shuddered

She was obviously shy and shorter than her two companions. She had semi spiky black hair and the smallest breasts of the three. She seemed to be almost hiding behind her friend.

"Okay that's enough!!! Leave this dorm now you bunch of hussies!!" Katsumi yelled as her hands started crackling with use of her quirk, only to be held down by Izuku's Quirk. Looking at him she pouted. "Izukuuuuuuu they need to leave, they don't deserve to look at you like that!"

"Katsumi, behave. You told me you wouldn't be overly possessive of me and here you are now twenty hours later acting like the same girl you were years ago. Now sit there quietly while I deal with this." He asked in a soft but firm tone.

"Yes sir. Sorry sir." Katsumi muttered, glaring daggers at the unexpected guests. She was trying not to be possessive, but it was hard when her private time with him got interrupted by some random people she had never even met before.

"Good girl. Now, one of you tell me who the hell you three are." Izuku said, rising from the bed and pushing the three newcomers against the wall. For all he knew they were assassins, they all were physically fit and one of them could run through walls. The comment about first year from the periwinkle haired one led him to understand they knew at least a little bit about him, or the environment at the very least.

"Hey! You can't just use your Quirk on people like that! And I thought sensei said males had weak Quirks!" The second girl complained while her friend tried to grow tentacles from her hand, only for them to be pinned by his Quirk as well. It was then that Izuku realized that the first girl wasn't there anymore.

Suddenly, Izuku felt someone put him in a full nelson from behind. "Hey, calm down." Was all Miria could get out before she was forced off of him by his powerful Quirk.

"I'm not going to take orders from the naked girl who ran through my wall before staring at my dick." Izuku said, holding her in the air this time so she had nothing to phase through.

"We're third years. Let us down and we can talk about this." Miria said, her bright smile not leaving her face.

Izuku reluctantly let them down while keeping focused in case he needed it. With a glance to the clock, he ascertained that it was early morning and they needed to be in class in about an hour.

"Thank you. I'm Miria, that girl over there in Nejire and the shy girl hiding behind her is Tamaki. We just wanted to come say hi, but didn't know what room was yours, so I ran through all of them." The blonde said, not even trying to cover herself.

"Hussies one, two, and three." Katsumi muttered, earning a small snort from an amused Izuku.

"I apologize for Kaachan's attitude, we will be having a little discussion about it I assure you." Izuku said with a sadistic smirk playing on his lips, all the while using his quirk to start teasing the blond in his bed again, causing her to let out soft mewls.

The other girls were a bit gobsmacked that he was openly teasing her that way, with Tamaki bright red in embarrassment.

"Sh-Should we go?" She stuttered, looking like she wanted to disappear completely as Katsumi writhed and moaned on the bed.

"Oh, I don't see why. I do have to get ready, but it's not like I'm losing clothes here, so I doubt it matters too much." Izuku mused as his clothes flew out of his dresser and began putting themselves on him.

"Eh, we should probably go anyway. Nice to meet you." Miria said, picking a pair of underwear and a T-shirt up off his dresser. "Hey, I need to borrow these, hope you don't mind." She said as she walked past Nejire and Tamaki, the latter looking adorably shy as she waved goodbye.

"I don't like it." Katsumi pouted, looking even cuter with her tsundere-like blush.

"What don't you like, Kacchan?" Izuku asked as he gathered her clothes and helped into them despite her not actually needing help.

"It's nothing." Katsumi said, not meeting his eyes. She knew she was basically on lock to be his first wife, but she still didn't want him to distance himself from her if he thought she was trying to be controlling again.

"C'mon, my adorable little firecracker, tell me. I won't judge you for your feelings, just your actions, I promise. Tell me what you don't like." Izuku said in a gentle voice to the blond bombshell.

"Fine, other girls. I know I have to share you and all that bullshit, but I invested so much time into our relationship! I don't like the idea of girls just waltzing up, flashing their tits, and then getting to date you too." Katsumi said, crossing her arms over her chest. She wasn't used to being so open with her emotions, preferring to bottle them up and release them by blowing things up, but with Izuku she didn't mind as much.

"Huh, I think I see what you mean. You're worried that some girl is going to have just as much time as you, but none of the work you put in, is that it?" Izuku asked, tilting her head up so she had to face him.

"Yeah. That's about it." Katsumi said with fiery red cheeks.

"Well, how about this? If I go after a girl and try to date her, you have to accept my decision, but if a girl is pursuing me, you can stop them until I intervene. Deal?" Izuku asked, gently tugging her head back by her hair so he could pepper kisses up and down her neck.

"Deal. Thanks Izu, Iloveyou." She muttered quickly and under her breath, not meeting his eyes as she sat on his bed.

"Awe, I love you too, Kacchan. C'mon, we shouldn't be late for our second day."

Toshinoko Yagi, more commonly known as All Might, wiped the blood from her mouth. She had a class to teach soon and according to the roster, there was a male with an extremely powerful Quirk.

The world had separated Quirks into categories based on it's raw power, from best to worst it went S, A, B, C, D, and E. The only issue is the strongest Quirk ever recorded in a male was a low D. This led Toshinoko to the only natural conclusion: this young man may have come in contact with All For One.

Both All for One and One for All were S class Quirks, and Endeavor's Hellflame was a high A class, so the fact that a male was able to destroy a mock city was a big deal.

A timer went off on her watch and she went into her buff form, making her body look like her predecessor and mentor, Nana. All Might opened the door wide and allowed air to fill her powerful lungs. "I AM HERE! ENTERING THE DOOR LIKE A HERO!" She bellowed, flinging the door open and entering with a dramatic flourish.

"Holy shit, it's All Might!" Izuku said in a rare burst of intense emotion, causing all of the desks to float into the air and drawing yelps of surprise from the girls in his class."Oh, sorry about that." Izuku said, carefully reigning his emotions back in and lowering his classmates.

"Um, yes, I am glad to know you are a fan. Anyhow, when you first arrive at the scene of heroism the first thing they will always see is your costume!" All Might said, gesturing to the wall and causing it to slide out and reveal several boxes with hero costumes inside. "Get changed and meet me outside for my personal favorite: COMBAT TRAINING!"

The students all filed out of the classroom and towards the locker room, aside from Izuku.

Izuku went to the bathroom that had been designated as the boys' locker room with his hero costume, setting the case down. He started removing his school uniform and put it on the bench that was set up in the room.

Unknown to him there had been a hole drilled into the wall, or purposely left, you never know with Nezu, in the next room all clamoring to get a look at the male in the next room. "Ashido come on, let me see!" Ekio complained as her pink best friend stood at the hole.

"Quiet Kiri, I don't want him to know what we are doing!" She whispered as she felt her nether regions start dampening. This man was extremely fit, and with a quirk like that he was the perfect male!

"I would…also like to see, for research purposes of course." The normally stoic and calm Momo was blushing and rubbing her thighs together at the thought of seeing a fine male specimen naked.

Iida stood there completely flabbergasted and horrified at the way his fellow classmates treated the man. "You should not be peeping at all, this is very unhero-like!" The girl yelled as she chopped her hands.

While this was going on Katsumi was changing and trying her best to ignore the others. Once she finished she slammed her locker getting the others attention. "Look, extras, we have All Might as a teacher, do you think a pro like her would accept us being late!?" She grabbed her grenade gauntlets, the same ones that Izuku and her had designed as kids and put them on. If one looked closely they would see on the inner arm that she had them engraved. 'For my Izu' on it.

They all finished getting ready and began walking to the mock city where they found All Might standing next to two spinners with colored balls inside them.

"Greetings, zygotes! I have selected your teams already and your matchups as well!" All Might declared with a brilliant smile, her electric blue eyes glowing in her now-black sclera as she gestured to a holographic screen that read:

Izuku Midoriya Kyoka Jiro (Team A) vs. Katsumi Bakugo Tenya Iida (Team D)

Shoko Todoroki Meza Shoji (Team B) vs. Mashira Ojiro Toru Hagakure (Team I)

Fumiko Tokoyami Tsuyu Asui (Team H) vs. Eiko Kirishima Hanta Sero (Team J)

Denko Kaminari Ochako Uraraka (Team G) vs. Momo Yaoyorozu Ibara Shiozaki (Team C)

Yuga Aoyama Mina Ashido (Team E) vs. Rikida Sato Koja Koda (Team F)

"The heroes of the first round will be young Midoriya and young Jiro, with the part of the villains being played by Bakugo and Iida. I will give you a few moments to get to know your teammates before I explain the challenge." All Might declared, giving them the time so she could observe and understand more about young Midoriya.

Jiro was awkward as she walked with the guy she didn't know even a little bit, but she was still supposed to go against some of the stronger students with him.

'Then again…' she thought, remembering what he had done the day before at the apprehension test. She didn't necessarily think that this was in the bag, but she knew that she shouldn't sell him short.

"Alright, I guess I'll start talking first. What's your Quirk, Jiro, was it?" Izuku said, idly spinning small rocks around his head.

"Uh, yeah. I have enhanced hearing, even more so when I plug my jacks into something. They can pierce concrete but my ears bleed if I use my Quirk too much. Oh, I also can use my heartbeat as a weapon with the speakers in my shoes." Jiro said, her jacks tapping together in a display of her nervousness. She wasn't usually fond of meeting new people.

"Your jacks, huh? Would you mind if I took a look at them? I'm sorry, I'm a bit of a Quirk nerd." Izuku asked, a rare blush slightly painting his cheeks.

"Sure, knock yourself out." Jiro said. 'I mean, as long as he just looks and doesn't to-' Jiro's brain completely shut down as she felt Izuku take one of them between two fingers and tug on it gently. Her jacks had always been an erogenous zone, not that she used them like that, she just knew from previous experience that she shouldn't touch the metal parts because the slight rubbing drove her crazy.

"Hey Jiro, are you okay?" Izuku asked, tugging on her jack to get her attention.

"Yes Da- Midoriya. Sorry, I didn't think you'd g-grab them, just thought you'd look like you said." Jiro managed, trying to cool her body temperature by sheer force of will.

"Oh shit, is it painful?" Izuku asked, dropping the jack and looking apologetic. He had no reason to dislike Jiro, so he hoped he didn't cause her any pain.

"Um, yeah, I mean, no, sorry, it's fine." Jiro said, looking for any reason to change the subject. "D-Do you have a girlfriend or something?" 'holy shit I'm a fucking idiot why did I ask him that!'

Chuckling, Izuku shook his head. "Not really? I mean Kaachan said she wants to earn being my girlfriend even though technically she is my property more than anything right now." He turned and looked back at Jiro with a smirk. "Why do you ask?"

Jiro was saved from answering because All Might decided that was enough time to learn about each other. "All right, students! Here is the script! Ahem, the villains have constructed or otherwise acquired a powerful explosive device! The heroes must find and make physical contact with the large bomb before the timer runs out. The villains will receive a ten minute headstart in order to hide the bomb."

Jiro avoided talking to Izuku while Katsumi and Iida went off to hide the bomb in the building, only talking to him when they were walking towards the building.

"W-What's the plan?" Jiro asked him, still mortified over the fact that she almost called him Daddy. She didn't even know that was one of her kinks!

"Very simple. Can you use your Quirk to find things like sonar?" Izuku asked as he tossed his small rocks against the wall.

"Sure, what am I looking for?" She asked, happy he wasn't bringing up the 'daddy' thing. That was something she would have to unpack later when she was alone. She would be fine as long as Izuku and Katsumi weren't too loud.

"The bomb. Just tell me what floor it's on." Izuku said as he stood back and Jiro stabbed her jack into the wall.

"They are on the twenty seventh floor. They are arguing about you. Iida is calling you useless and Bakugo sounds like she wants to kill her." Jiro reported, hoping Izuku would start his plan to avoid Iida getting thrown out the window.

"Alright, thanks." Izuku said with eyes closed, holding out his hand, his eyes glowing green enough to shine through his eyelids.

Suddenly, his eyes flew open and the entire face of the building was torn off, exposing the different floors and allowing the bomb to slide out on its own and float down to meet Izuku's open hand while Iida screamed in frustration.

Jiro flinched as a rock fell towards her, and prepared to dodge the debris, only for it to freeze in place and act as an umbrella for her against the other falling rocks.

"THE HEROES HAVE WON!" All Might said over the intercom, ending the battle and causing Izuku and Jiro to start the walk back to the observation deck and Katsumi to storm down the stairs, wanting nothing more than to beat the shit out of Iida for what she said about her Izu.

When they were all in the observation tower All Might addressed her entire class. "Alright, students! Who would you say the MVP was for that match?"

Katsumi and Izuku spoke at the same time.

"Obviously Izu." Katsumi said with crossed arms as if All Might was stupid to ask at all.

"Definitely Jiro." Izuku said, shocking everyone in the class aside from Momo, and painting a deep blush onto the aforementioned rocker's face.

"Alright, Bakugo, why do you name young Midoriya as the MVP?" All Might asked, already knowing the answer.

"Oh, I don't know, maybe the building that was torn apart? He even shielded Ears from the crumbling building. Dumbass." Katsumi said before feeling the slight pressure of his Quirk against her neck, telling her to stop the insults.

"Oh, I suppose that is a good reason to declare him the winner. Midoriya, why did you say Jiro." All Might asked, genuinely wanting to hear this.

"What good is overwhelming strength with no focus? Without Jiro, I would have had to level the entire building to find the bomb without entering. This method had minimal danger for casualties and ended the encounter quickly." Izuku said, making Jiro hide her face in shy embarrassment as he gave her credit for the whole plan.

"I-I see. From that point of view, Jiro was definitely the MVP and will be receiving… EXTRA CREDIT!" All Might said, before looking at her notes. "Alright, next group! Please make your way into the city!"

After the class was over the heroes in training went back to go change, with Katsumi still seething from whatever it was that Iida had said.

When they got into the locker room she went right up into the blue haired girl's face and growled "You ever, and I mean ever, say anything like that about my Izu ever again and I will make sure your hero career ends right then and there. Do you get me you pompous extra bitch!" Katsumi raged in her face. She was sure Izuku wouldn't be mad over her outburst here.

"I…well he is a male I never thought a man would have such power and conviction…" Iida stammered out, clearly shaken by how angry Katsumi was.

"Izuku has more bravery and courage than you will ever hope to have." She said with finality before walking to her locker to change. Leaving the other girls in shock.

Unknown to them Izuku had heard the whole thing and while he was happy that Katsumi was defending him she still felt that she needed some punishment, or maybe it was a reward at this point.

Waiting until she was naked, he used his quirk very subtly and started to tease at her pussy causing her to tense up a bit and whisper. "Izuku, I've been so bad please punish me." She continued to try and get dressed while Izuku used his quirk to tease and mess with her.

Jirou heard what the girl had said and started peeking over, blushing as she noticed Katsumi's nipples getting teased and tugged on by some unknown force, and she wasn't the only one who noticed. Momo, Mina, and even the powerful bicolored girl also seemed to notice and snuck glances over at her as she was teased by Izuku.

Mina slowly and subtly made her way towards the hole with her eyes fixed on Katsumi, only to bump into a blushing Jiro, who had already occupied the seat by the hole.

"Hey Jiro, fancy seeing you here." Mina said with a smirk, enjoying the amount that the goth rocker girl blushed after that.
