AN: I do not own My Hero Academia or any of the characters.

First chapter: Noumu!Izuku Part 1. Focuses on Izuku's relationship with his classmates and teachers as a noumu.

To say the air surrounding class 1-A was strained would have been an understatement. It wasn't everyday a class of first year high school students had to deal with the aftermath of one of their own classmates being kidnapped, tortured hurt, and experimented on by the League of Villains. Only the U.A. teachers and Inko Midoriya understood how it felt to have lost someone so important, to have had a treasured student, friend, and son go through something like their boy had. Recovery was slow and somewhat unproductive, the victim in question return the same yet not the same simultaneously.

Izuku Midoriya, for a better lack of words, was a noumu now.

No, he was not a creature black as tar with exposed brain tissue and fundamentally mindless. While his genetic structure was altered, showing definite signs of possessing new quirks, he still looked like the ordinary boy that entered U.A. several months ago.

Save for his eyes of course. His brilliant green irises were still present, but the whites of his eyes were now black like All Might and Mina's.

Then there was his mental and emotional state. Cognitively speaking he seemed fine, but from the moment he was saved thanks to a successful hero raid it was obvious he wasn't all there.

When he was rescued he'd been unresponsive to the rescue team consisting of several pro heroes. All Might and Aizawa were at the scene once their student had been safely extracted, gently handed over to them by a giant Mt. Lady with a concerned look on her face. No one could get him to speak. He merely blinked while staring straight ahead, his obsidian and emerald eyes screaming in fear.

They rushed him to the hospital where Recovery Girl was waiting.

After finding nothing physically wrong with him, it was a matter of waiting until the boy's mother arrived. It was only when she entered his hospital room that he showed any hint of emotion, his body reacting for him by pulling the woman in for a desperate hug as soon as she'd reached his bedside. Still, his eyes had stayed wide open even as tears escaped them.

A week later, when they finally coaxed him into speaking, he told All Might to kill him.

"M-mom," he stated brokenly, his voice sore from disuse. The woman in question smiled, crying tears of joy at the word. Her boy was finally speaking again! "I love you."

She threw her arms around him, hugging his now thinner body close.

"I love you too, sweetie. Oh, Izuku, my baby, I've missed the sound of your voice so much. I've missed you so much."

"I know." He hugged her back, his lips quirking up just a tiny bit. Everyone else in the room could tell he was faking it for his mother's sake. "B-but, can you leave the room for just a minute? There's something I need to tell the heroes that I don't want you to hear. Please."

A flash of hurt flashed in her eyes, but it vanished as soon as it came.

"Sure thing, Izuku. Just holler when you're done."

"I will. Thank you, mom."

The moment she was out of the room, Izuku turned to All Might looking more serious that he'd ever seen him.

"All Might," he demanded, ignoring everyone else in the room completely, "you need to kill me."

Aizawa had wished the boy's classmates hadn't been standing there behind their teacher to hear that. It only made his job of asking them to leave the room while they talked to their student so much harder.

"You don't understand." He'd whispered after listening to All Might and Aizawa tell him how they could not carry out his request. "If he finds me, he'll order me to kill you. He'll order me to kill my friends, maybe even my own mom. I can't let that happen. I won't be able to stop myself though, and because of what he did to me I can't even trust myself to be able to kill myself. The quirks make sure of that."

Both of the teachers froze.

Quirks?

It had taken two more full days to get a story out of the boy. Broken sentences that stated he'd been hurt, healed, tortured, and in utter hell around the clock before they finally decided to turn him into a noumu of some sort came to the surface. He admitted he got twitchy, lost his mind if he wasn't given an order every so often. He got even more desperate when he explained he would be hard pressed to ignore a direct order from Shigaraki from now on. It was visualized to be like a switch in his head that he couldn't turn off. He was terrified he would hurt someone because of it.

"They trained me to never ignore an order from my… master. If Shigaraki," he flinched, "ever orders me to do something I will have to listen. It's like something else takes over when he talks to me. I black out until whatever I was told to do is carried through, until I receive another order, or am told to back down. All other orders given by anybody else come second to him. I'm… I'm so sorry. I wish I had more control, but I don't I tried for days to resist. I really, really did."

All Might could feel his heart breaking.

"My boy, what did he make you do?"

Izuku closed his eyes.

"I can't remember. All I remember is waking up to another noumu's dead body on the ground in front of me one time. Other time I woke up in—" His breath hitched as his hands curled around his forearms tightly. He squeezed himself so hard his nails cut skin.

"Young Midoriya, you do not have to continue."

Aizawa nodded in agreement. "He's right. Don't push yourself."

The greenette shook his head.

"No. I need to say it, because I'll never be able to forget. I vaguely remember Toga Himiko ordering me around one night after Shigaraki grew bored with me. She must have told me to hold still, because I remember coming out of it as she sliced me up over and over again in her bed. It hurt so bad I screamed once I was able too, but by that point she just ordered me to do something else. After that I woke up in her bed hours later. I… I wasn't wearing any clothes, but…"

A whine broke from him then. All Might cried freely as he watched his student stare at them in regret, embarrassment, and raw anguish. Even the usually cool Aizawa couldn't stop himself from punching the wall beside him so hard his knuckles split open. He silently paged for a nurse to assist him with the damage as All Might wrapped the boy in his arms and cried enough for both of them.

All the adults could do was silently vow to put those villains behind bars as soon as possible.

Nevertheless, despite how much Izuku wanted to be locked up so Shigaraki could never get to him, All Might convinced him to come back to school. Everyone begged to see him, wished to help him heal, and wanted to figure out how he could get past the changes he had no control over.

They needed to see him smile again.

In the end the only reason he said yes was because he had a couple new quirks that he needed to learn how to control.

"They gave me another form of shock absorption that turns any damage I receive into kinetic energy I can then store up," he explained to his classmates, teachers, and authorities separately. "I also possess some sort of healing quirk. Not full regeneration like the first noumu we encountered at the USJ, but I'm capable of healing from lacerations, burns, poisons, broken bones, and a few other physical injuries."

No one had pushed him to find out how he knew those things. They already guessed the answer. He'd been gone for barely a week, yet the horror they had caused during that time felt like a couple of lifetime's worth.

There was one added comfort though. It came with Aizawa taking precautionary measures and having Hatsume from the Support Course make the invention Izuku had asked about upon All Might refusing to kill him.

"They're noise cancelling headphone-earmuff thingies, just like you asked for." The pink-haired girl reassured her recently rescued friend. "Once you put them on not even Present Mic's voice will be able to get through. I also installed that other feature you wanted. In case of emergencies where you think they might be taken off, just rotate either one of the circles on either side and the rest of the center piece will transform them into a helmet that can only be taken off with your verbal command of 'helmet off' or by me manually overriding it."

Izuku had been so grateful he missed the frown on his friend's face as she walked away.

Moving back into the dorms had been tricky too.

"Aizawa-sensei?"

"Yes, Midoriya?"

"Is it okay for me to move my room to be the vacant one next to Kacchan's room? If anything happens I feel more comfortable having him right next door, and Todoroki would only be a floor above and Iida a floor below too. I feel like it's safer than me staying where I am now on the second floor. Not that Tokoyami, Aoyama, and Mineta wouldn't be able to handle me or aren't great friends, it's just…"

His teacher cut him off with a sigh.

"If it puts your mind at ease then that is fine with me. Let your classmates or myself know if you need help moving your things, and I can go get you the other key right now."

Izuku seemed as if he was going to cry, but no tears came out. This observation made Aizawa's stomach twist uncomfortably. Had he cried at all since he'd been rescued?

They had also needed to come up with a code for when Izuku… relapsed. His psychological requirement to be ordered around was sickening, objectively speaking, because it was born from the experiments and genetic changes he'd undergone while captured. It hadn't been a huge problem during his hospital stay since he'd taken plenty of what he saw as orders (suggestions) from the doctors, Recovery Girl, his teachers, and mother as what he needed. Only after being released from his hospital room where people phrased things more as questions was when it had first happened. It had been horrifying to watch.

"Aizawa-sensei," Izuku was suddenly gasping. He'd gone pale and shaking just moments before, barely a minute passing before he recalled what his dependence felt like. "You need to tell me to do something. Give me an order!"

"Midoriya, what are you—?"

"Please! Just do it!"

It was such an unreal experience that it had taken Aizawa a few precious seconds to realize what was going on. They had hoped he'd recovered from it after all the treatments and talks he'd been given. As a teacher he should have known just because the signs were invisible didn't mean they weren't there.

Aizawa did what he was told.

"Midoriya, please sit down."

A flip switched in Izuku's head. His eyes glazed over suddenly, his body going ridged as he followed the command immediately. Once he was sitting it took several seconds for his eyes to go from looking far away to clearing back up. When they did clear back up he looked ashamed.

"I'm sorry you had to deal with that, sensei. I didn't…" He closed his eyes tightly, his lower lip wobbling but still no tears escaped him.

Forcing himself to unclench his fists in anger, the homeroom teacher made to comfort the boy. What else could he do during a time like this? There was no point in making a promise of it getting better; it would be as good as lying to the boy. Everyone was in the dark about the situation. Izuku Midoriya was a noumu now, plain and simple, but he was unlike any noumu they had information on. He was an anomaly.

Still, he was human too. Just a boy.

"Don't worry about it, kid. We'll figure something out. Did you know you'd have an attack coming, or was it sudden?"

"I think I felt it start stirring in my head ten minutes ago, but it hadn't happened like that in so long I'd forgotten the feeling. It only really became bad when my muscles started itching for something to do, and my head started hurting. It felt like something other than myself was getting ready to panic, but…" He trailed off for a moment before whispering. "I think that was still me."

"We'll have to come up with a code word or phrase for when you get that urge again. Do you know how often that happens?"

"I'm not sure. Once a day maybe? Sometimes it's twice a day, but a few times it's none at all. Um, for a phrase, did you have anything in mind? If not, I think I have an idea."

"And what's that?"

"What do you need from me?"

Aizawa seemed hesitant. "That's a bit too common of a question, isn't it?"

"Not really. I usually ask 'What can I do for you?', so having 'What do you need from me?' be the phrase will mean if we're ever in a public situation it would be casual enough to not sound too strange. Also, it's something easy for the rest of the class and teachers to know in case that happens again."

And so it was decided.

The concern about having been ordered into passing on One For All was also cleared up rather early on, Izuku explaining their tactic hadn't worked since he wasn't passing it on willingly despite acting as if he was. That had been a relief for everyone involved. The villains wouldn't be able to get their hands on that sort of power anytime soon.

That is, as long as Izuku never received an order from Shigaraki.
