Aizawa and his two problem children.

Last and first day

"Yes, well, Izuku isn't you." It was like he teleported as Aizawa was now directly behind Toshinori.

"A warning, Aizawa!" Aizawa had startled Toshinori so badly that it accidentally caused the older man to puff up into All Might by accident. There was a gush of blood that exited All Might's mouth before he immediately reverted back down into Small Might. "Warn a guy when you do that!"

Aizawa ignored Toshinori's yell and simply lightly hit the top of Toshinori's head with the down side of his fist. It clearly didn't hurt as it was less than a tap of pressure. "Izuku isn't you. You can't compare him to yourself. You may have immediately understood how this power works but he doesn't. We need to fix that as soon as possible so he's not always breaking his bones. Izuku, show him."

"I had a theory that I could maybe displace my power. So, with dad's permission, I threw a ball to see how far I could throw it using One for All. I used the power with my fingers instead of my arm. The ball went pretty far and my theory was right... but uh..." Izuku made an ashamed face as he pulled up his right sleeve to show Toshinori his two main fingers bandaged and were placed in a splint.

Toshinori was gentle as he grabbed the injured hand to inspect it. Izuku's index and middle fingers were purple in color as well as tied together with the splint. Leading down from his two fingers was a brace attaching around his wrist to limit movement to his two fingers. "Does it hurt?"

Aizawa didn't even hesitate as he smacked the back of Toshinori's head. Toshinori flinched at the sudden attack. "Does that hurt, jackass?"

"Point taken, thank you Aizawa." Toshinori's voice was curt as he rubbed at the back of his head.

"I can handle it." Izuku smiled at Toshinori. "I have a really high pain tolerance! Once when I was eight I dislocated my shoulder and didn't even scream... Hichan did though..."

"That he does have. I've never seen a child with such a high pain tolerance." Aizawa clicked his tongue against the roof of his mouth a few times as he shook his head.

"I see." Toshinori gave Izuku his hand back. "So you can put power behind your limbs."

"Yeah, but I still break my bones."

"Yes, we should get together for training. So we can stop this from happening. The sooner the better in my book!" Toshinori smiled and placed his hands on his hips. "When's a good time for you, Aizawa?"

"I'm thinking once his fingers heal. I'm taking him to see Recovery Girl tomorrow, hopefully this will be the last time we bug that poor old woman." Aizawa reached across and pulled on Izuku's ear. Not enough to hurt but enough to gain his attention. "Look, I don't want you constantly going to Recovery Girl with broken bones when you're in UA. She knows I'm your father and it reflects back on me."

"Understood." Izuku slightly whimpered and Aizawa let go of his ear.

"Now," Aizawa focused back around to Toshinori. "I've already set him up for quirk counseling, that'll start next week. Combined with his acrobatics classes once a week, training with me, studies, and now with his memory appointment-"

"His what?" Toshinori blinked in surprise.

"...You never told him." Aizawa swiftly looked at Izuku. Izuku's eyes went wide as he tried to think back to his talks with Toshinori, all the times they were alone together, Izuku never once brought up his missing memories.

"No... I don't think I did. I'm sorry, All Might. I'm missing memories."

There was a spray of blood that released from Toshinori's mouth like a wild fountain. "Wha-"
