The Successor (My Hero Academia)

“I’m going to try and fix her, I think.”
 
The moment the words leave Izuku’s mouth, he feels his own sincerity. He knows that this is what he wants to do. Doesn’t stop him from getting a little bit embarrassed when Tomura lets out a guffaw of laughter a second later however. Shooting the older boy a half-hearted glare, Izuku ultimately just sighs as his ‘big bro’ eventually calms down.
 
Shaking his head, wiping tears from his eyes, Tomura takes one look at Izuku’s petulant face and then snickers as he speaks in a teasing voice, lightly mocking in tone.
 
“Bro, do you hear what you sound like? ‘No seriously, I can fix her!’. It’s a total meme, bro!”
 
Yes, he’d known why Tomura was laughing from the moment he’d started. Izuku just rolls his eyes, unable to help the exasperated but also fond smile that spreads across his face at the older boy’s antics. It was a little funny… but at the same time, it was this girl’s life. Himiko Toga didn’t deserve her fate. And Izuku… Izuku wanted to find a way to support her. To help her move on. To maybe help her live a satisfying if not normal life.
 
With that in mind, Izuku finally pushes off of the bar stool and makes his way across the room. He does so slowly, meandering over to where Himiko is tied to a chair. To be fair… what he’s decided to do isn’t the easiest path, not by a long shot. His options varied, but he was already dead set on the one that would likely prove the hardest to implement.
 
After all, it would be child’s play to just remove Himiko’s Quirk and force her to live without it, to see if that would repair her mental state over time. It would be equally simple to remove her Quirk and replace it with another from his library that didn’t have any mental component to it.
 
But Izuku had already decided to go with Door Number Three. He was going to remove Himiko’s Quirk for the purposes of modifying it and then giving it back to her. Was this a good idea? Maybe not… but here he was all the same, approaching her as the blonde watches him with wide, hopeful eyes.
 
She clearly wants him to have his way with her. She also clearly still wants to stab him and make him bleed. Himiko has more than a few screws loose in that head of hers. Izuku doesn’t doubt her obsession with him is very real, just like he doesn’t doubt she would most certainly try to harm him if he didn’t have her tied up. For this young woman, the two were NOT mutually exclusive.
 
Still, as he reaches for her, he hates how excited she’s getting. She has no idea what’s coming and that… that honestly makes him feel a little guilty. As such, before he lays his hands on her he hesitates and shakes his head.
 
“I’m not going to fuck you, Himiko. Not now. Not while you’re thirsting for my blood and picturing me covered in red.”
 
Himiko flushes beneath the gag, the way her eyes flutter making it clear that was exactly what she was imagining right now. Izuku chuckles softly and rolls his eyes. Then, he gets serious again.
 
“I’m going to take your Quirk. Only temporarily. Only so I can try and modify it. But I’m going to take your Quirk and it’s not likely to be fun for you. I’m sorry in advance for any pain you feel from its absence.”
 
THAT garners quite the reaction from the poor young woman. His first sentence makes her go still in abject shock and incredulity. But as he keeps speaking, Himiko seems to realize he’s serious. At which point, she starts shaking her head wildly, her eyes going wide as he reaches for her with a sigh.
 
“Mmph! MMMPH!”
 
“It’s alright, Himiko. It’s going to be alright.”
 
With a single touch, the deed is done. Himiko Toga’s Quirk, Transform, is now Izuku’s. He doesn’t rip it away from her or anything like that. He’s gotten good at this over the years. He gently pulls it off of her, making sure there’s no actual pain as she loses access to an extra limb she’s had all her life. That doesn’t mean it’s not incredibly disconcerting… and horrifying for the bound and gagged young woman.
 
For a moment, Himiko just sits there in a state of shock. Izuku even wonders if he underestimated the mental effect her Quirk was having on her psyche. If it turned out that just removing her Quirk made her feel better after all, he would have to reconsider whether he was going to give it back, even in a modified form.
 
… But no. The moment of shock passes and Himiko begins to cry. She looks at him, sobbing brokenly, begging through her gag for him to return it.
 
“Mmm! Nnngh! Mmmph!”
 
Izuku tries to give her a reassuring smile, even as he steps back, already mentally manhandling her Quirk within his internal space.
 
“Just relax Himiko. It’s only temporary. I promise, I’ll give it back. I just need to modify it first.”
 
This does not appease the young woman he has tied up in front of him. It does not make her feel better. But then, Izuku had known it probably wouldn’t. The first option he’d considered, that of removing Himiko’s Quirk to see if it would eventually let her live a normal life… that was an option that would have taken weeks if not months to bear fruit. He had never truly expected her to just be fine on the very first day.
 
That said, Izuku frowns as he focuses on her Quirk. Transform is an interesting Quirk. He has complete knowledge of it now that it’s part of his library. It was a pretty versatile Quirk too, except for the blood activation component. It allowed Himiko to mimic everything from a person’s body to their voice. Hell, if she got naked ahead of time, she could even mimic their clothing, which was… well, pretty wild.
 
It did not let her use the Quirks of those she transformed into… but there was potential for it to become more. This was something Izuku was well aware of. Quirks could undergo Awakenings under the right emotional conditions. The proper catalyst could make someone’s Quirk stronger, could unlock it’s true potential as far as Izuku saw it.
 
Himiko, if she ever reached the right point, could turn Transform into an Awakened Quirk. It would then likely allow her to use the Quirks of others that she turned into, though there would probably be some sort of condition to it.
 
Ah, but Izuku was getting distracted. He had promised he would return Himiko’s Quirk to her after all, and that was what he was going to do. Just as soon as he’d modified it in a way that would make her less of a psychopathic blood-obsessed yandere.
 
Unfortunately, that’s easier said then done. As Izuku stands there in front of a sobbing, whimpering, tied up Himiko Toga, the most he figures out is that he CAN do it. He can modify Quirks. But it’s not easy, nor is it fast. He needs… time with Transform. He needs to have it within his library for longer than five minutes, to dissolve it’s hard exterior and let him at its creamy center.
 
More than that, he can’t figure out exactly how he wants to modify it, at least not off the top of his head. This… this wasn’t going to be something that he could handle in a half hour. Tch.
 
Pulling himself back into the real world, Izuku grimaces as he looks down at Himiko. The girl is still crying, but has her head hanging low in defeat now as she sits there still tied to the chair. Izuku frowns… and comes to a decision on the spot. On the one hand, letting Himiko get used to living without her Quirk constantly prodding her might be good for her. On the other hand, forcing her to live without her only constant companion for any length of time was cruel and unusual punishment… even if she probably HAD murdered people.
 
Letting out a sigh, Izuku steps forward and splays his fingers across Himiko’s skull. Before the young woman can react to his touch, he’s already sent her into a deep, deep sleep. It’s a temporary coma that will end on its own within seventy-two hours… but Izuku intends to be back before that timer runs out anyways.
 
As Himiko slumps forward further, now unconscious, Izuku looks over to Tomura. The older boy has been watching all of this from the bar and tilts his head to the side questioningly as Izuku finally turns back to him.
 
“I’ve taken her Quirk. I’m going to work on modifying it before I give it back to her. That will… hopefully help with the worst of her impulses. But for now, please look after her for me over the course of the next day. She will not wake up until I return.”
 
Chuckling, Tomura gives him a grin and a simple thumbs up.
 
“Sure bro. You can count on me. Though… jeez, you’re not going to get any sleep, are you? I know what you’re like, Izuku.”
 
Well, it was already very late. Practically early morning. He might as well stay up and work on Himiko’s problem, right? Sure, he knew there was a time lock he had to get past in order to soften up Transform before he could properly work on it, but that didn’t mean he couldn’t… try and speed up the process, right?
 
Izuku just shrugs at Tomura’s pointed accusation, before glancing at Himiko one final time.
 
“Thanks Tomura. Kurogiri.”
 
At hearing his name, Kurogiri forms a portal for Izuku to step into, one that deposits him back at his house in his bedroom. Tomura is right though. He doesn’t get a wink of sleep before he needs to get dressed and get ready for the day.
 
-x-X-x-
 
To be fair… no one notices that he’s running on anything less than one hundred percent. And really, one night of no sleep isn’t going to kill him. It doesn’t even truly affect him. Izuku has a multitude of Quirks that allow him to run on zero sleep for a while, and he’s not above using them even if some have detrimental costs.
 
Nor is he above using Quirks that allow him to essentially run on auto-pilot while he focuses his true attention inward on the problem that is Himiko’s Quirk. As the hours go by, Transform… settles down for lack of a better phrase. It ‘relaxes’ into Izuku’s internal space, allowing him to poke and prod it more and more. As it becomes malleable, he’s able to pressure it to change in tons of different ways. Like for instance, adding or removing minutes from the length of time that Transform lasts after its user consumes blood.
 
He's also able to isolate the mental component and keep it from affecting him at all, but he’s not able to severe it completely. Not yet anyways. It’s too tied into the Quirk, specifically into the part of the Quirk that requires Himiko to drink blood before she can use it.
 
As Izuku is working on this, his body is going through the paces in the real world. He’s distantly aware of going to class at U.A., and even exchanging some small talk with his fellow students. None of them suspect a thing, even as the days goes by. However, when lunch comes… that’s when Izuku finds himself dragged to the roof of the school building by one Momo Yaoyorozu. The real one this time.
 
Reluctantly, he disentangles himself from his work on modifying Himiko’s Quirk and pushes his focus back into the real world. As he does so, it’s to find Momo on her knees in front of him, sucking his cock already and getting him nice and hard. Izuku, for his part, has one hand atop her head, his fingers sliding around the base of her ponytail and splaying out over her skull.
 
Letting out a shuddering sigh, Izuku stares down into the heiress’ eyes, before giving her a smile. A break was probably just what he needed so that he could approach the project regarding Transform with fresh eyes after lunch was over. Meanwhile, Momo is as eager and enthusiastic as ever, bobbing up and down on every inch of his cock with a gusto. It makes him wonder if she’s more interested in making a lunch of his cum then she is of eating one of those two fancy-looking bento boxes that she’s set off to the side for them to consume after she’s done.
 
Still, he’s not about to deny her this. In fact, he quite enjoys how far she’s come. She’s still not a very experienced cock sucker, but she’s no longer as amateurish as she once was. Hm, had she been practicing on toys or fruits or something? Izuku groans, tilting his head back and letting his eyes drift shut for a moment in enjoyment. Then, he feels it rising up within him.
 
“Getting close, Momo…”
 
The black-haired heiress doesn’t hesitate to take him even faster into her mouth, until finally she sucks him to completion and drains his balls dry, swallowing every last drop of seed that he has to offer. Izuku groans in appreciation, before watching through lidded eyes as she pulls back off of his cock, licks him clean, and then tucks him back into his boxers and fixes up his pants.
 
Smirking a little bit, he sits down with her in order to eat the bento she’s brought him. However, Momo is quiet as they eat, not seeming to have anything to say. Izuku is just beginning to consider whether he should just slip back onto auto-pilot and return to his library, when she finally works up the courage to speak.
 
“I-Izuku… will you be my boyfriend?”
 
Blinking, Izuku looks over at Momo in surprise. To her credit, she’s looking at him with determination. She’s not the kind of girl who would look away or act shy after asking such a question, he supposed. But then… how was Izuku supposed to answer her, really?
 
On the one hand… Momo was someone he could see himself marrying one day. For not just the sake of his plans, but also because he liked her as a person. On the other hand… they had yet to discuss the fact that he was getting it on with multiple other women. More than that, Momo KNEW he was getting it on with multiple other women. She’d spied on him not once, but twice so far.
 
Tilting his head to the side, Izuku decides then and there that he can’t keep beating around the bush on this.
 
“Momo… I know you’ve been watching me.”
 
The heiress goes still, a bright red blush spreading across her face as she quickly averts her eyes. Finally though, she speaks.
 
“Y-Yes… yes, I like watching you with other women, Izuku…”
 
She trails off, but Izuku can tell there’s more than that. And so he waits patiently, interested to hear WHY Momo likes watching him with other women.
