Being friends with Izuku Midoriya since childhood meant a lot of things. Including beating back bullies from when he was Quirkless. Katsuki Bakugou can attest to that. You were one of his biggest supporters in becoming a hero. So is it any surprise that you were the first to find out All Might himself was training him to be his successor? That you knew about One For All?
The two were bad liars. At first you were suspicious of the skinny skeleton like man, but soon that gave away to concern over to his health when you saw him cough up blood. And after insisting on helping Izuku learn the skills to fight as well as build up his muscles, it didn't take long for you to brought into the secrets. Not just that of One For All, but that All Might has a time limit in how long he can stay in buff form.
Now after almost a year since that day, you are looking forward to having a fairly quiet few weeks. The USJ incident, the Sports Festival and the Hosu Attack were a lot on your nerves. Of course fate had other plans. Before homeroom starts Aizawa, better known as Pro Hero Eraserhead, pulls you and Izuku aside. "Look, I'm not normally in the business of sharing details about faculty, but this is going to be well known soon enough. All Might got hit by a Quirk on his way to U.A, and it's...making him act irrationally. The only reason I am telling you two this is because he's been asking for you."
The two of you didn't even need to think before grabbing your things and heading to Recovery Girl's office. She didn't stop the two of you. You were both greeted with a smiling Toshinori "Ah! Hello! Shouldn't you both be in school?"
Everything seemed normal till you noticed his eyes, the blue colour of them replaced with bright pink eyes. "U-uh you Sensei Aizawa told us you were asking for us?" Izuku said, slightly nervous, his quick mind trying to figure out what Quirk Toshinori had been hit by.
