Chapter 1: Limitless

Izuku Midoriya couldn't wait for his quirk to arrive. His whole class already had one and he already is 4, so it should come soon!

And it seems that today is the day!

He woke up and went to the bathroom to wash his teeth and he saw that his eyes weren't green anymore... but blue! He grinned, thinking that it was his quirk. And he was right.

He ran towards his mom's room and opened the door "Mom! I have my quirk!" He screamed as the door was sent flying away.

Izuku grinned. He is super strong now! But... he still broke the door... and part of the kitchen... and the entrance door.

"Izuku?" His mom yawned "What's wrong?"

He grinned and hugged her "I got my quirk mom! Isn't it cool!" His mom didn't answer instead, he felt how she slowly...

Disappeared.

"Mom?" Izuku looked up to see his mom slowly disintegrating until there was nothing else.

Izuku only screamed in horror.

*Hours Later, Hospital*

Izuku was sat on a hospital bed, with white bandages over his eyes as doctors were studying his quirk via blood samples.

"This... is incredible. A quirk that can control space to an atomic level! I never seen a quirk so powerful!" A doctor said and his college nodded.

"And dangerous in the same note. If he can't control it, what happened in that building would be the least of our problems." He said "He should be watched by a pro-hero to avoid a situation like this."

"Yeah, but who?"

"Excuse me, but is Izuku Midoriya here?" The doctors looked down to the voice of an... animal in a suit with scars on its face.

"Principal Nezu, right? From UA?"

Nezu nodded "That's right! I came to see Young Midoriya! Is he available?"

One doctor nodded "Y-Yes, he is. But, why would you want to-" Nezu ignored him and went towards the door of the room where Izuku was.

Izuku looked to the direction of the door opening and tilted his head "H-Hello?"

Nezu chuckled "Hello! You might be wondering what I am? A dog? A mouse? A-"

"You are a mouse. From what I can see a Mus Musculus, a house mouse." Izuku interrupted and Nezu blinked before chuckling.

"How right. Say, how can you know that without seeing?" He asked and Izuku shrugged.

"I can see. Well, kinda." He said and Nezu sat next to him.

"Mind to explain that to me?"

Izuku rubbed the back of his head "I can still see, maybe even better than before. Not because of the bandages, but... my eyes seem to be-"

Nezu chuckled and nodded "The doctors called your quirk, your eyes, Limitless. The power to control space to an atomic level. You understand what that means?"

Izuku nodded "I can control matter, right?"

Nezu clapped "Exactly! And as a teacher, I want to make sure you learn how to control it! For you to become a hero!"

Izuku shook his head "Thank you but... I don't think I can be a hero."

Nezu tilted his head smiling "Oh? Why is that?"

Izuku felt tears coming to his eyes "I... killed my mom... my neighbors. I am not a hero."

"Hmmm." Nezu mused "You are right. You are not a hero." He said and placed a paw on his shoulder "But you can be one. You need to trust me; you need to let me teach you. What you say Young Midoriya?"

Izuku gulped and gripped his hospital gown. "I..."

"I want to be a hero."

Nezu smiled "Excellent. Let me now manage your liberation from the hospital."

*Years Later*

Izuku, now wearing a green hoodie, a black blindfold making his hair spike up and jeans with black leather shoes was playing chess with his guardian, Nezu in his office.

"So, how can I avoid becoming a student here?" Izuku asked with a smile and Nezu hummed moving his piece.

"I don't know what you are talking about, Izuku."

Izuku chuckled hearing that and moved his piece "I think you do. I had been living with heroes and training under them since I was 4. and I really do think I can just be a hero from the get go."

Nezu laughed "Maybe you are right. But don't you think that would be unfair? A 15-year-old becoming a hero without studying for it?" He then moved his piece and drank a bit of tea.

Izuku nodded "I know. That's why I have a suggestion for you." he then moved his piece.

Nezu smiled "You want to teach."

Izuku nodded "That's right! I think I can be a great teacher and while I am at that, I can work for my license, right?" he then moved his piece and took one from Nezu.

Nezu laughed "The board will be unhappy, but I will allow it, with some conditions." Izuku nodded and Nezu continued "You will be in all heroic classes, one half of the day will be in 1-A, and the other in 1-B. You will have to teach all combat classes in the first-year classes, and you will tutor someone of your choosing." He said as they played.

Izuku nodded "Then we have a deal." He took out his phone and texted one of his friends. After one notification Izuku grinned "Done."

Nezu nodded "Excellent, I hope that you will enjoy teaching here, Midoriya Sensei. And..."

Izuku raised a brow "And?"

"Checkmate." Izuku laughed and nodded.

"Nice game Nezu. Now, I have to go and prepare my student. I only have 10 months after all."

Nezu watched him leave and chuckled as he drank his tea.

*At a Park*

"What you say over the phone... you were serious?" Shinso Hitoshi asked and Izuku nodded.

"You can bet your cat that I am! I just gave you my spot in UA! No need to thank me." He said hugging Shinso shoulder.

Shinso smiled "But... what about you? What are you going to do?"

"Shinso, Shinso... I am going to be a teacher there."

Shinso gave him a blank look "Now I don't know if this is a prank."

"It isn't! Is it that hard to believe?"

"Yes."

Izuku laughed "Well anyway, as your future personal teacher, I am going to make sure you are ready for everything and anything!"

Shinso shook his head with a smile "Whatever. When do we start?"

Izuku smirked "Now."

Shinso eyes widened "Hold on! I am not ready!"

"Villains won't wait for you to be ready! Neither will I!"

"W-Wait!"

Shinso 10 months of tortu- I mean training started.
