A Curious Scientist(slightly illegal and highly unethical)

Chapter 8

The next morning, Izuku finds himself being questioned by Himiko during breakfast.

"So Midoriya-san, you're focusing on learning everything that can be done to the human body via special drugs and manipulating quirk factors, right?" Himiko asks in between bites of pancake.

Izuku nods, taking a drink from his cup of milk. "Yeah, what about it?"

"What are you planning to do with Kazumi's quirk?"

Izuku raises an eyebrow at the protective tone of Himiko's voice as she asks the question. "Her quirk itself is nothing special. Cat mutation quirks are a dime a dozen, especially ones as simple as her's. It's her body that I have plans for." He responds, causing Himiko's eyes to narrow.

"What does that mean?" She asks, preparing to pounce on him and tear his throat out if he gives an answer she doesn't like.

Izuku waves her off. "Calm down, it's nothing weird. I'm referring to her unique musculature and skeletal structure. Her muscle fibers are several times denser than those of a regular person, giving her extreme levels of super strength. Now, this SHOULD limit her speed and flexibility, but it doesn't. In fact, she also has vastly superhuman speed, and peak-human flexibility. I'm planning to use her body as a model to improve my own, or at least try to. I'll probably have to sit back and recover for a while after doing so if I do it the normal way, so instead I'll just create a clone of myself with those features once I figure out how, and I'll move my brain into that body, discarding this one." He explains.

Himiko blinks. "Oh. That doesn't seem very safe. It also doesn't seem very sane."

Izuku finishes his food and milk, and stands up from the table. "Safety is not a concern, and sanity is overrated."

Himiko sighs as she watches him walk off, knowing full well that he said exactly what he meant.

"I'm sorry, I must have misheard you, you want me to help your successor do WHAT!?" Izuku yells, appalled and enraged at what All For One has just requested of him.

"No, I'm sure you heard me just fine." The ancient villain says with his signature grin. "I want you to assist Tomura in his invasion of UA."

Izuku glares at him. "Yeah, you're right, I heard you." He says, frustrated. "Of all the harebrained, idiotic things your successor could want to start off with, invading UA is near the top of the stupidity list."

"On that, you and I agree." All For One says with a nod. "I entirely intend for him to fail in his goal. This will function as a lesson for him, a lesson in humility and not becoming overconfident. I only learned that lesson 5 years ago, when All Might defeated me and left me in this state. It is imperative that Tomura does not make the same mistake. I am requesting for you to go with him in order to prevent him from getting captured or wounded too severely."

Izuku raises an eyebrow. "And why me? I'm sure that you have more qualified pawns for this task."

All For One shrugs. "True, I do have pawns that are stronger than you, given your quirkless nature." He says, seemingly agreeing. "However, the augmentations you have built into your clothing give you the edge, alongside your unparalleled genius. Plus, you are not like my pawns, rather, you are a trusted ally, not a subordinate."

Izuku sighs. "There's no way I can convince you to send someone else, is there?" He asks rhetorically, continuing before All For One can even try to respond. "Though, I will be taking blood samples of the students and teachers there. And, if any of the students experience unnecessary pain before they die, if they even end up dying, then there will be hell to pay. Am I clear?" He asks, the tone of his voice causing even All For One to shiver.

"Crystal."

"For the record, I think you're an idiot and a Man-Child."" Izuku says after Tomura explains his plan, which is honestly not much of a plan at all.

Tomura glares at him, before turning to the Nomu at his side. "Seriously, Kurogiri, who the hell is this guy? You told me that he's an ally of Sensei, but you refuse to say who the hell he is."

"At my request." Izuku interjects. "My identity is none of your concern, all you need to know is that I'm an currently working WITH All For One, rather than for him, and that I'm the scientist who creates the drug that he's using to slowly heal himself."

Tomura glares at him once again. "Then fucking make it faster then!"

Izuku sighs. "I literally can't. The only way to speed up the process at the present is to re-inflict the wounds that All Might dealt, but that would kill him as my drug cannot regenerate the brain, and his life is hanging by a thread as is. The only way that he survived last time was by Garaki manually repairing his brain after it was crushed. He barely managed to do it then, and no longer possesses the materials he used to pull it off, as he used them up preparing the high-end Nomu that he was tasked with creating before I came into the picture."

Tomura scoffs. "Whatever, you better not bail on me tomorrow, or I'll kill your fucking cat."

Izuku raises an eyebrow. "2 things. 1, I don't have a cat. 2, the closest thing there is to a cat in my lab is a little girl whose sister would render your corpse unrecognizable if you tried to do ANYTHING to her." He says, deadpan, before a portal opens behind him, created by the tech built into his suit. "See you tomorrow, Shigaraki."
