The Successor (My Hero Academia)

She takes another step closer, her hand still busy under her skirt and stuffed down her panties. Meanwhile, her grin grows wider as Izuku’s eyes narrow.
 
“My, Momo. What big teeth you have.”
 
She doesn’t even miss a beat.
 
“Hehe! All the better to gobble you up with! C’mon, Izuku! Fuck me! I need it! I neeeeed it!”
 
He considers it, even with his suspicion building. But in the end… no. No, there are too many issues with this situation. Not least of which he’s already had a long day.
 
“How about tomorrow, Momo. Now’s not a good time. Not a good place either. You’re the Heiress of a Multi-Billion Dollar International Company. Think of your image. Besides, we’ll see each other at school tomorrow, won’t we? We’ll fuck then… like we always do.”
 
There it is. A flicker as his suggestion that they wait until tomorrow is processed. ‘Momo’ scowls ever so briefly, before going right back to smiling at him with that sharp grin of hers.
 
“I can’t wait that long, Izuku! Who cares about my reputation, anyways~ It doesn’t matter! None of it matters except for you!”
 
Izuku just grunts at that, even as she bounces forward, her breasts jiggling in her schoolgirl top. She’s not wearing a bra, he notes. Her tits are going all over the place within the confines of her shirt.
 
“I care about your reputation. Don’t you remember, Momo? We’re going to get married, and you’re going to help me take your family for all they’re worth. You promised. You can’t do that if you’re disowned for indecency, now can you?”
 
Another momentary flicker, the briefest of pauses, and then back to being all smiles.
 
“Uh-huh. Don’t worry I-zu-ku~ I remember my promise. I swear I’ll-!”
 
She finally gets into range of him. What sort of range, you might ask? The sort of range that allows her to finally swing that knife she’s been hiding behind her back in her free hand out and attempt to stab it down towards his shoulder. Izuku, of course, is ready for her. His senses enhanced; his body strengthened. He grits his teeth as he moves with rapid speed, catching her wrist with bone-jarring force that has ‘Momo’ squeaking as she’s suddenly caught in his grasp.
 
“Sorry, I told a fib. Haven’t let the real Momo know about my plans to marry her quite yet. We haven’t made any promises like that. And we still haven’t… because you’re NOT Momo Yaoyorozu. Who are you? Reveal yourself!”
 
There’s a pause, as the pretender wearing Momo’s face stares at him blankly, clearly shocked to have been found out. Izuku, meanwhile, is trying but failing to figure out just who the hell he’s dealing with. He has no clue and that… that’s bad. She’s obviously been stalking him. She’s been following him long enough to know about his relationship with Momo for instance. But who could she truly be? Who-
 
Izuku’s thought processes are abruptly derailed as he watches Momo’s face melt away, revealing the young woman underneath. He can’t say with absolute certainty that this is her real face… but he believes it is. Mostly because with his hold on her, he can feel her Quirk at work, can feel her rescinding its effect. More than that though? Well, he recognizes the woman in front of him.
 
“You… you were in the forest that day.”
 
The blonde’s eyes widen with happiness, her lips curling back into a toothy, gleeful grin.
 
“O-Oh! You remember! You did see me! I wondered! I hoped! Ahh… Izuku Midoriya, you’re really special, aren’t you!”
 
Eyes narrowing, Izuku’s other hand snaps out. The blonde lets go of her knife and it drops into her other hand, allowing her to try to stab him again. But Izuku is ready for her, grabbing her second wrist and trapping her hands both. The knife strains for a moment in her grasp, but ultimately there’s nothing she can do. He’s far stronger than her.
 
This was the woman that Izuku had registered in the forest the day he fought and defeated Katsumi Bakugou. After kicking Katsumi’s ass, he’d left her to stew in her tumultuous feelings of arousal, shame, and humiliation. And for a moment, he’d used his extrasensory Quirks to make sure she didn’t follow him. She didn’t, of course… but this girl did. Had she happened upon their battle? Had she been tasked with following him or something? Looking into her wide eyes and staring at her manic grin, Izuku didn’t get the impression that she was anyone’s agent, to be honest.
 
… Had she been following him all this time, since that incident in the woods?
 
“Who are you? What do you want with me?”
 
Licking her lips, panting noisily in a way that would make it clear how aroused she was if the scent of her lewd desire wasn’t already filling his enhanced nostrils, the blonde grins.
 
“H-Himiko Toga! My name is Himiko Toga! And I want… I want to see you bleed! Please-!”
 
Izuku’s eyes narrow as she tries to kick him mid-word, aiming to use his ironclad grip on her wrists to leap up and kick off his chest. He’s able to easily redirect her motion of course, while avoiding that knife of hers as well. Spinning her around, he yanks her back against his chest, frowning. Her Quirk… he’s getting a better handle on it now. She can transform into anyone who’s blood she ingests. The more blood she drinks, the longer she can pretend to be that person.
 
… That begged the question of where she’d gotten Momo’s blood. Was the other girl okay?
 
“You… what did you do to Momo? Did you hurt her?”
 
She squirms against his chest but can’t escape his hold.
 
“A-Aha… aha… n-no! Not yet! Mm, I’d like to see her bleed too… she’s so wonderful… so p-perfect for you I-zu-ku~”
 
The girl… this Himiko Toga… she was insane. But the more Izuku looks at her Quirk, he wonders if that’s entirely her fault. Quirks weren’t fully understood, not by a long shot. He and his father had a greater understanding of them then most though. Looking at Himiko, really LOOKING at her… he would bet money that her Quirk is influencing her mental state. More than that, it’s been doing so for a long, long time.
 
Yet, he can’t dwell on that right now. He doesn’t believe her, knowing how her Quirk works. That said, he can’t give away he knows how Himiko’s Quirk works…
 
For a moment, Izuku is tempted to give Himiko what she wants, blood letting and all, in the hopes that it might calm her down… but no. He needs to know more than he currently does before he goes and sticks his dick in crazy.
 
“Tch. Kurogiri!”
 
It takes less than a moment for a portal to appear before Izuku and Himiko. The blonde squeaks, as he forces them both through it and into Kurogiri’s Bar.
 
-x-X-x-
 
“Thank you again for this, Tomura. I didn’t expect to have to trouble you again so soon, but I found myself blindsided.”
 
“Heh, no problem bro. Always happy to help out. Though I always thought you’d bring one of your other girlfriends here first, haha!”
 
Izuku smiles at Tomura’s joke, but it’s something of a wan smile that doesn’t really reach his eyes. The two of them sit on a pair of barstools, with Izuku’s phone and a police file laid out in front of him.
 
It’s been about two hours since he dragged Himiko off of the street and came here. In those two hours, several things have happened. For one, Izuku had done the most immediate wellness check he could and texted Momo to see how she was doing. He’d gotten a response back in mere moments, and while it was clear she was a little embarrassed to have been spying on him, Rumi, and Ryuko back at UA, she wasn’t hurt. She didn’t mention a single attack from a crazed stalker.
 
However Himiko got Momo’s blood, she’d apparently done it without interacting with the other girl directly. Which really only left one moment where the blonde could have gotten access. Izuku didn’t want to think about it, to be honest. Now that he knew Momo was alright, he could focus on Himiko herself.
 
That’s where Tomura and his League came in. Izuku was supposed to be the next Number One Pro Hero. But he was still a kid. He didn’t have the sort of above the board sources that wouldn’t raise suspicion. Nana could have made an official inquiry, but it would have taken time and likely have drawn some eyes that Izuku didn’t want.
 
Tomura and his League on the other hand… they could get their hands dirty. They were the ones who had their fingers in all the pies. Including the Police Department. That was where Tomura had gotten Izuku a file on one Himiko Toga on such short notice. The file that Izuku was reading even now, his eyes sliding back and forth across the reports.
 
Apparently, the girl had suffered a psychotic break a few months ago. Her teachers called her a ‘cheerful and well-behaved girl’, and she was said to have been a relatively normal student who had plenty of friends. Of course, said friends were quick to distance themselves from her when she was caught taking a box cutter to one of her classmates, after which she used a straw to suck out his blood.
 
… Yeah, Izuku supposed that would be a rather jarring change for most people to deal with. However… however, it was the reports of how her parents had reacted when questioned by news stations that had him wondering.
 
Her parents hadn’t been shocked. The detective in charge of her case made note of this in the file. Her parents, when questioned by both police and the news, had only apologized and claimed they’d tried their best to help their daughter. They claimed that she was a lost cause, had always been a lost cause… and more than that, they labeled her a demon, a monster in human skin who they had publicly declared on national television they hoped would be put down once and for all before she could hurt anyone else.
 
They’d disowned her. Parents, abandoning their only child like that. Now, on the one hand, her crimes were rather sick and demented. But on the other hand, by all accounts she’d been a model citizen before she snapped. The parents should have been shocked and horrified, just like her teachers and classmates were. Instead, it was like they’d been waiting for her to turn evil or something. They said it themselves… they always knew she was a lost cause.
 
With what he was able to glean from her Quirk, Izuku could easily put together the events. Quirks… Quirks liked to be used. That might have sounded strange, as though it was attributing too much of a personality to Quirks. And maybe it was. Except, Izuku and his father knew full well that some Quirks were special. More than that, some Quirks could grow, could evolve, could become something more.
 
And above all, Quirks liked to be used. Don’t use your Quirk? It can wreak havoc on your mental state, and eventually ruin you.
 
Of course, some Quirks sucked. Some Quirks, if you used them, could be actively detrimental to your own health. Was Himiko’s Quirk quite that bad? Perhaps not. Perhaps if she’d simply been raised in a nurturing environment, and if she’d been taken to the right specialists to be trained in the proper use of her Quirk… but no. It was obvious that her parents had caught her using her Quirk at a young age and promptly freaked out. Whether her Quirk had pushed her to cut herself or maybe a small animal so she could see the blood… it didn’t really matter.
 
Her parents had not been supportive. Izuku can easily read between the lines and see exactly what sort of life Himiko Toga had been forced to live. Her Quirk was influencing her from a young age, but it was only after she felt like she was forced to suppress who she really was that it started fucking with her mind something fierce. That she’d fought it for so long, that she’d pushed down the urges and pretended to be a normal girl for so damn long… it was honestly somewhat admirable.
 
Through no fault of her own, Himiko Toga had been turned into a ticking time bomb. By her Quirk, by her parents, by her environment. And to continue that analogy… she was in the middle of exploding right now. She was a bomb that had gone off and was still going off to this day. If he let her go, she’d probably come after him or those he cared about, forcing him to take drastic action. If anyone else got ahold of her, they’d either kill her or exploit her, more than likely.
 
“What’re you gonna do with her, bro?”
 
Glancing to Tomura, Izuku sighs as he turns on the stool and looks across the room where Himiko is currently tied to a chair, her arms and legs restrained quite effectively, and a gag stuffed in her mouth. The moment he looks at her, she moans through the gag, all but hip thrusting at him in need. Staring at her, Izuku feels more pity than arousal. She’s not in her right mind. Then again, what does her right mind even look like after spending all her life being influenced by her Quirk?
 
He could… he could take her Quirk from her. He might even be able to modify it given some time. It wasn’t something his father could do, but Izuku is not his father. He’s been playing around with some of his Quirks. Trying to tweak them. If he could remove the mental component from Himiko’s Quirk, he could give it back to her and she would be just fine. Or he could even give her another Quirk from his library.
 
Though, that all hinged on whether or not the removal of her Quirk would actually fix her mental state or not. Izuku didn’t doubt that her Quirk had played a big part in who she’d ultimately become, but he also didn’t doubt that her parents had played just as big, if not a bigger part. There was every possibility that taking Himiko’s Quirk wouldn’t actually help her at all.
 
But he wouldn’t really know until he tried…
