Lonely Ninth

Preperation

Izuku was escorted to a meeting room, still in full costume. He opened the door, and was greeted with dead silence as the UA staff, a police detective, Sir Nighteye and a short, yellow costumed man stared at him.

"Come in Mr Midoriya! Please, take a seat!" Nezu said.

Izuku sat down on Nezu's left, while Aizawa took the seat to Nezu's right.

"Now, as everyone here is aware, you are the ninth wielder of One for All, correct?" The rat asked.

Izuku nodded.

"That is correct." He said.

"How much control do you have over One for All?" The short yellow hero asked.

"I had 75 percent when I registered it, and recently got it to 100 percent. I've been training hard with One for All, and can use about 120 percent of All Might's full strength from his prime." He replied.

"How much have you used for training excersises?" Aizawa asked.

"30 percent for speed, 15 percent at most for hitting opponents. 15 percent can break bones, 30 percent can rupture organs. 40 percent is fatal to a normal person." Izuku said.

"Would you mind returning to school tomorrow to conduct some tests?" Nezu asked.

Izuku nodded.

"Sure, I can come in tomorrow."

Aizawa sighed.

"Alright, go back to homeroom. I'll be there shortly to talk to the class." He said.

Izuku stood from his seat, bowing politely to the heroes as he left.

  Izuku was confronted by Yayorozu and Jirou once Aizawa dismissed the class. The hero raised an eyebrow as he left the classroom, but exited after everybody else.

  "Midoriya..." Yayorozu began.

  "Do you have All Might's quirk?" Jirou blurted. The two stared at her. "What? I just didn't want to beat around the bush like Momo was going to."

  She turned her attention back to Izuku, her eyebrows raised. The greenette just sighed at their expectant expressions.

  "Yes. But you cannot tell anyone. Understand?" He said.

  Both the girls nodded quickly.

  "How do you create those blackwhips? Are they your original quirk or a part of One for All?" Yayorozu asked excitedly.

  Izuku sighed internally. This was probably going to take a while.

_______________

Izuku tugged his PE kit on, leaving the changing room and walking up to gym Gamma. Aizawa, Nezu, Sir Nighteye, Endeavour and the old yellow hero were waiting for him there.

"Midoriya, you're right on time! We're going to be doing a few tests and excersises to find the limits of One for All that you've reached. Is that alright with you?" Nezu asked.

  Izuku just nodded, accepting the ball from Aizawa. The greenette stepped into the circle, and threw the ball with all his might.

_____________

  They calculated and recorded a large variety of scores and results. Flight speed, Blackwhip grip strength, Blackwhip reach, Danger Sense radius, Smokescreen light dilution, One for All running speed, grip strength and jump height.

  Aizawa removed his capture weapon, putting it on the ground next to Nezu.

  "Alright Midoriya, last test. Quirkless hand to hand. I'd like you to spar with Aizawa here, to just see how you are at quirkless combat."

  Izuku nodded, taking a few steps away from the heroes. Aizawa did the same, setting his capture weapon to the side.

  "Begin!" Nezu chirped from the side.

  Izuku darted forwards, keeping his eyes locked on Aizawa's hands and feet. The teacher's stance shifted, his right foot slightly further back than his left, while his right hand pulled back for a punch.

  Izuku deflected the feint and blocked Aizawa's sweeping leg. The greenette tugged the hero forwards, who twisted his body in response and lashed out with his fists.

  The student leaned back, pulling Aizawa's leg with him. The hero stumbled, losing his balance. Izuku's right leg lashed out, sweeping his teacher's left leg out from under him.

  Aizawa was pinned easily, and Izuku was declared the winner.

  Sir Nighteye stepped forwards, his critical eyes scanning Izuku. He tossed a small object to the boy.

  Izuku caught the object, looking at it held in the palm of his hand. It was some kind of stamp?

  Sir Nighteye didn't say a word, just smiling satisfactorily. The shorter yellow costumed hero hobbled over with his walking stick.

  "Alright boy, now let's see how you do against an opponent using their quirk!" He said, grinning viciously.

  The small man flew into the sky with a whoosh of air. Izuku barely registered Danger Sense and dodged when the hero went flying through where his head had been previously.

____________

  Izuku sat on the sofa with his weights in his hands, curling his biceps back and forth. It took 300 reps for him to even start feeling discomfort in his arms.

  He would train One for All until he was twice as strong as All Might ever was. All for One wouldn't stand a chance.

  The students were given a week off due to the incident, so Izuku spent that time training. He sold his old weights and bought much heavier ones. He got through a pair of trainers with his training, and needed to buy new ones.

  He did pushups, sit-ups and squats, he ran for hours at a time, and whenever he wasn't running he was lifting weights. He trained the user's quirks throughout the day, using Blackwhip to grab things, fine tuning his control of Smokescreen in his room, excersizing on the ceiling and using Float hidden in the woods.
