Issues of Quirk Compatibility

Chapter 3: That is Not the Proper Response to a Rescue!

"Speaking" "Thinking" [Sound effects] Quirk Names and Special Attacks

In her search for the power to surpass All Might, Endeavor turned to a Quirk research lab. Little did she know that this would usher in the age of the Heroine and dating by statistics. What's a quirkless hero to do in a world like this? Make your Vows Izuku; Massive Gender-bends, Deku/harem, Crack with Plot.

This story is rated M for a lot of suggestive content, if that was not clear. I hope you all enjoy the special twist that the vows and spirits add to the romance. I wanted to tie in the harem with his combat growth so that every time another girl joins his harem the reaction isn't "Oh, another one." But "Aw yeah! Another one!"

Sometimes it's difficult remembering to write Izuku at his base as the blushing cinnamon roll after just finishing the first season of "Issues of Honor" where the main character was totally F-ing done with it all. It's fun seeing the difference between them.

I always like it when fictional stories dig a bit deeper into their characters powers and allow them to develop tangential abilities. For a great example, check out the Espers of A certain Scientific Railgun. The character's ability is electricity, but electricity is also magnetism: hence the signature railgun attack. I wonder if anyone picked up on the little clue I placed in how I will be doing that in this story? Insistent terminology is sometimes important.

Izuku and his class are aged up by about four years. Need to get those hormones pumping at full and the advertisements to have time to convince nearly the whole country.

Anyway, the gist of this story is that Izuku makes his hero's journey in a world where almost all pro heroes are women, and he's a prime steak slathered in fan-service. Either that, or it's a deep and thoughtful examination of the objectification and empowerment of female super-heroes by the reversal of traditional gender roles. You'll see as it goes. Beware of Crack and other absurdities. But for now, On to the Story!

-Police Interview Room 2-

Katsu looked around the familiar bland room in her bland replacement clothes and sighed. A twitchy first-timer would probably assume that they were trying to make the guest nervous with the long wait, but in reality there just weren't enough people to have someone interview her right now. After all, who would want to be in the police when you could be a hero? The mass of former heroes being replaced by heroines arguably made the situation worse. Sure, some of the former heroes joined the police, but many became villains or vigilantes. There was talk of turning the police into another 'harem profession' like heroing, but it never got off the ground without support from the major hero agencies and schools.

Poke. Poke. "Hey, I'm bored. I know you can hear me, don't pretend you can't. C'mon, it won't be that hard, just give me some fire to play with, or you can let me take your body for a spin, or we can see where they're keeping Izuku and cuddle."

After all, even the hero schools and offices still had to meet quotas. The CMR (Committee for Men's Rights) had pushed through some stupid regulation that all professions and universities had to hire or admit at least one male for every four females or face a heavy fine. In most professions, it wasn't a problem. Hero work, on the other hand, was heavily female dominated and many of the males who did join were only in it for the harem.

Poke Poke Poke Poke. "I you keep ignoring me, I'll make you regret it! I'll set off your quirk while you're trying to sleep! I'll make you sweat every time your boyfriend is near! I'll mess up your hair so bad your own momma won't recognize ya'!"

It wasn't an impossible goal. Support and business classes counted as hero work too, since they were needed to keep the agencies running. A lot of places took the practice of having one or two male secretaries that weren't expected to actually do work, but instead acted more like a house husband for the whole office. The net was still deciding between the terms 'sexretary' and 'fucretary.'

Katsu finally snapped. "Lay off it already! I can't have them thinking I'm a lunatic delinquent if I want to get into U.A!" She glared at the scarlet woman splayed out on the interrogation table. "Who the fuck are you anyway? The police all acted like you weren't there."

The stranger flipped herself over so that her head was hanging over the edge of the table looking up at the blonde. "I'm Efreet, the spirit of fire, power, lust, and maybe anger on a bad day." Poke "And you, my host, are Katsu Bakugou," Poke "age 18," Poke "height 166 cm," Poke "blood type A," Poke "you like spicy food, stuff your bra, and explode whenever Izuku touches you." Poke Poke Poke "Your favorite position is cowgirl, and you want to singlehandedly solve the population decline with at least nine children."

Katsu swatted the hand away when it went for another poke. "Shut up Hot Wings! You never explained what you are and why no one else can see you!"

Efreet smirked at finally getting a reaction out of the girl. She twisted around to be sitting up on top of the table. "I told you, I'm a spirit. Izuku summoned me through your thoughts, and now I'm a part of you. Why don't you think of me like a sexy twin that's a part of your quirk."

The blonde growled. "I know my quirk, and you sure as hell ain't a part of it!"

The spirit put on an innocent face. "Oh? Not even if I guarantee that you'll get your man? Not even if I give you time every week to do whatever you want with him?"

A new voice interrupted the two girls' bickering. "As intriguing as listening to you talk to yourself is, I have a mountain of paperwork that needs to be filled out, so I'd like to get this over with."

Efreet smirked and hopped off the table to reveal a police officer with the head of a cat sitting across from the blonde. "The bitch was blocking my view intentionally!"

The man took Katsu's silence as acceptance. "Good. Now, your fiancée gave us the information we need to make this an open and shut case, we just need to confirm some things with you. First, did you provoke the villainess in any way to attack you?"

Katsu thought back, and decided that a straight answer would be best in this case. "I was speaking about my Izuku, and the Sludge Bitch got jealous. That's the only reason I can think of."

The man nodded. "The use of your quirk in that situation is excused, since it was self-defense. However, that last attack was both excessive, and far beyond anything that your quirk ability tests in school said you should be capable of. Can you explain what happened there?"

Efreet poked the girl in the side. "You're welcome for that, by the way."

The explosive girl shot a glare at the spirit. "I don't really know. One second my Deku was singing and my head was filled with fire, then the next that fire was outside. It felt like a whole forest had been set ablaze at the same time from a single spark. I can't explain it…"

The man sighed heavily. "I suppose that's good for you since we can't exactly charge you for excessive force when you couldn't control what happened. There will be no charges against you or your boyfriend. I do have an offer for you though. Doctors Enryo and Miku Todoroki want to interview you and would be willing to pay quite well for any information about what happened. They're just outside the door, if you're willing to talk."

The fire spirit hopped up and down in excitement. "Money? Fuck yeah! Jewelry and lingerie here I come!"

Katsu hated the fact that she agreed. "I'll tell them whatever they need to know."

The cat faced office nodded and opened the door. "She's willing. You can-"

Before the man had even gotten halfway through, a woman littered with tools and steam-punk style goggles slipped through and nearly tackled the blonde girl. "Did you do it? What did it feel like? Can you fly now? Tell me!"

A red haired man pulled the other doctor off of the girl and did his best to restrain his wife. "I'm sorry, but this has the potential to be the biggest breakthrough since the development of Double X."

Katsu was nowhere on the same p[age as these people. "What? What do you think happened?"

The woman slipped out of her husband's arms to look right into the girl's eyes. "Your boyfriend doesn't have a quirk, your own quirk doesn't act the way we saw from the videos, the only explanation is that you had a quirk evolution! Tell me, do things seem different now? Does your quirk feel different? I NEED TO KNOW!"

As the man restrained his wife again, Efreet took a sitting position in midair to watch the show. "I like this woman. She has passion."

Katsu took a glance at the floating spirit. "May as well tell them. With all the crazy things that quirks can do, they'd have no reason to doubt me." "Yeah, I got an invisible tag-along with delusions of grandeur." She topped it off by gesturing in the offended spirit's direction.

The woman shot out of her husband's arms again and started frantically searching the room with her goggles. The man gave another sigh and sunk into one of the chairs. "I'm sorry about Miku, she always gets excited whenever the possibility of research comes up. I barely get a moment's rest between her and our little Mei." He ran his fingers through his hair and Katsu noticed a surprising amount of gray hairs. "Anyway, I'm Enryo Todoroki of Quirk Reseach Labs. As Miku said, the only explanation we can come up with for what happened is that you had a spontaneous Quirk Evolution." At the girl's confused look, he gave a little chuckle. "Never heard of it? You wouldn't be the first. It hasn't happened naturally since the age of heroes began a hundred years ago. But before heroes, back in the Mini Dark Age caused by the first emergence of quirks, there are tales of people's power spontaneously growing or changing. If we can figure out what causes this, it will be an unprecedented breakthrough in our understanding of quirks."

Katsu glanced over at the woman to see her fruitlessly trying to catch the fire spirit, who was treating the scientist's attempts like a game. "How very scientific."

Enryo gave a sheepish smile. "Her methods may seem unusual, but she'll chase a problem down from miles away and isn't afraid to think outside the box. That's essential for work like ours. Now, could you tell me everything that lead up to the evolution in reverse order?"

The girl took a deep breath. "Right before the… evolution, I was listening to my toy sing. He did it to get the villain's attention so I could breathe. Right before it happened he took my hand and asked if I trusted him. When he finished his song, the evolution was done, I felt stronger than I ever did before, but I felt like I missed something. Like you lit a fuse on a bomb to destroy a building, and the building collapsed, but there was never an explosion. Like I fell asleep for the final battle of a movie. Everything was building up to… to… to something, and it happened without my knowing, but I know it did because now I have all this power and my tag-along." She shot another glare at the spirit who was dangling her tail just out of reach of the excited scientist. "Before that, the slime bitch tried to suffocate me-"

Miku suddenly flashed over to the blonde. "How long? Did you pass out? Did you think you were going to die?"

Katsu threw herself back to regain her personal space. "I don't know! I'm sorry I didn't keep a stop-watch when I was drowning to death!"

"Ah-ha! So you did think you were going to die! This is a great breakthrough!"

Katsu looked over to Enryo, who motioned for her to continue. "Before that it was just a normal boring day at school. The only interesting thing that happened is that I got a ring from my Izuku."

Miku pushed forward to invade the girl's space again. "How long? What kind? Are you married yet? What's your ring size? Was he wearing a ring too? How're his hands? Or did you progress to mouths yet? All the way? How big is he? Did you get off in the last 24 hours?"

Enryo once again reigned in his wife. "My apologies, you don't have to answer anything you are aren't comfortable saying."

Miku just cackled. "There's no need, her face says everything! Little Joli's going to love this… though I don't think Reiji is going to be able to give Joli what she needs. I always said she should've chosen a better man, she needs someone warm and cuddly instead of someone cold like him. Maybe if he could get her off, she wouldn't be so much of a grouch-pants all the time. I think it's good that he spends all his time in the hospital, it means she can find someone better for her. Actually" She turned her attention to Katsu. "Can we borrow you boyfriend? We need to test something."

The blonde felt her rage overflow. Her skin flushed red and wings of fire formed on her back. "HELL NO!"

Miku hopped up and down like a child that just got told they were getting a puppy for Christmas. "It has a transformation element! I knew it could break the typical bounds of quirks! Can you do more? Can we get a video? Does your skin feel different like that?"

The blonde's anger faded into annoyance and the transformation faded, leaving Efreet pouting at the missed opportunity. "Fine, but I'd damn well better get pay well for this shit."

-Izuku and Toshinori-

The young man looked around the junk strewn beach and had to admit that the hero certainly knew how to escape crowds of fans. No one would look for them here, even though they were on a public beach. People had gotten used to ignoring and avoiding the place that no one would pay any attention to them, even if things started getting interesting.

Izuku took a seat on a busted box TV. "So, how is this going to work? You're planning to pass your quirk down to me, but it's a commonly know fact that I don't have a quirk. People have my medical records. They know I have that extra joint on my toe, so we can't say that I'm just a late bloomer…"

Toshinori took a seat on a defunct washing machine. "One for All is one of a kind, the only quirk that can be passed down willingly. We need to keep it a secret from the general public, or else villains will come after you and those you love to force you to pass it down to them. One for All is a stockpile of energy, so if you use it carefully, then no one should know that you are using it. Of course, we'll need to start you on practicing it right away, so you'll be ready for the entrance exam." The hero swelled up and plucked a hair off his head for the boy. "Fortunately, you've already forged your body into a vessel worthy of the immense power contained in One for All. I'm confident that you'll be able to use it without too much damage."

Izuku stared at the hair All Might was holding out. "Aaaand what does the hair have to do with anything?"

"To pass on one for all you need to ingest the DNA of the former wielder. So eat it."

Once the boy choked down the hair, he looked up at his idol. "So now what?"

All Might deflated, but gained an excited gleam. "Now we wait for it to settle. And in the meantime, Can I have your autograph?"

-30 Minutes and 30 Autographs Later-

"... then she fell off the log bridge and into the stream. I tried to help her but she was really mad. She exploded at me! Literally exploded! Not just her hands, but her feet, and her legs, everywhere! She dried off, but it also ruined her clothes. She really wasn't happy about that. 'Those were my nice clothes. Mommy said I couldn't ruin them.' 'mommy said I can't let any boys see my undies or I'll get peg-ant.' Of course, I was just a kid too, so I thought it would make her feel better if I was in the same state as her. Then she got mad again and tackled me and shouted at me that I had to be the daddy and stuff like that until our moms found us. It was the next day that I discovered that I was quirkless and that my synergy was so high. I'd guess that's where her possessive streak got started." Izuku's ringtone cut off the conversation. "Oh, that's Katsu." The phone rang again while the fear evident on the boy's face grew. "I'd better answer it."

All Might examined his chosen successor once again. "It's obvious that the boy doesn't naturally have a body suited for hero work or wielding something like One for All, but he certainly has made himself into something that is. I'd guess that the boy is as strong as I was back when I first started using One for All. His face is the only place that has any softness, I'd wager. That cute face will help make him popular with women and kids, but it isn't exactly something that villains take seriously. But he has that vibe that makes people feel safe, like an older brother. All in all, he is an excellent candidate for Symbol of Peace who makes people feel at peace, even if he doesn't quite have my same deterrent quality... unless… could he weaponize his disappointment? I bet that would serve as a frighteningly effective deterrent for most villains."

"I'm sorry Katsu!" The hero took it as a negative sign that the boy's first response to getting a call from his girlfriends was fear and apologies. Did they have a fight recently? "No! Please, I'm with a hero- No, he's a guy, he's helping me- Yes I'm safe, not even any burns. You-" The young man vaguely resembling a rabbit being chased down by a fox, frightened and nearly doomed. The thought that this was perhaps not a healthy relationship began to grow in the blonde's mind. "But you're too important to me-"

"NO, YOU LISTEN TO ME, YOU SHITTY DEKU!" Both men turned at shivered at the sight of the exploding girl now stomping toward them through the junk. "You're not a hero, you're mine! I'm the hero in this situation! You're supposed to be in distress so I can punch the shit out of anyone who tries to steal you from me!" A wreath of flames surrounded the girl as she tried to grab her boyfriend's collar, only for it to turn to ash. She did the next best thing and grabbed his chin with her flame spewing hand. "You're mine and I'll kill anyone who tries to take you away from me! And I refuse to let you be hurt because you wanted to play hero!" The fire spread and destroyed another set of her boyfriends clothing, but she didn't care. She was blind to everything that wasn't he boyfriend's rebellion against her dominance.

Izuku, on the other hand, was very much aware of everything. It felt like someone had hooked him up to a nuclear reactor with how much energy was flowing through him. All of his senses were sharpened. He could hear every word Efreet whispered into Katsu's ear, egging her on. He could taste his girlfriend's signature hibiscus, now joined with a tantalizing cinnamon spice. He could smell her desire. And for what felt like the first time, he could truly see how utterly breath-taking beautiful she would be if she could learn her place.

A small part of his mind worried that perhaps absorbing the all the emotionally fueled fire was affecting his own emotions and desires. The thought consumed him for an instant, and he realized that it was likely true. At that point, however, he also decided that he didn't care.

Red lines of flame grew down his arm as he grasped the hand holding his chin. "No, Katsu. I'm not yours. You're mine!" He drew his arm back and pulled his mate into a searing kiss.

Katsu drew away first, gasping for breath. She gave a growl and tangled hers legs in his to bring them both down onto the sand. Satisfied that Izuku hit the ground first, she resumed her offensive.

All Might watched the couple wrestle for dominance and didn't know whether to feel proud or worried. On the one hand, the kid was already using All for One and wasn't hurting the girl too bad, if those moans were anything to go by. On the other hand, his chosen successor was using the power of All for One to make out with his girlfriend, and neither of them apparently had any idea where they were. This was a public beach, and it was littered with trash! It was a wonder neither of them bashed themselves on anything yet!

Still, there were really only two things he could do at this point. He could either risk himself and pull the two apart, or let the couple go at it until they tired themselves out. Unfortunately, there was really only one wise option.

The hero sighed as he started dragging away some trash so they wouldn't bash themselves on it. "stupid hormonal teens. They'd better appreciate this."

-Chapter 3 End-

Sorry for the shorter chapter, but that line was just too perfect not to finish with. Enjoy and kindly leave a review.
