You were a new transfer student that entered late into the year and got into class 1-A without realizing how dangerous it would be to be with them, Aizawa was not informed until later on the day you came in that he was getting a new student for his class

Aizawa: sighs and mumbles great, another problem child….

He stares at you and starts to speak coldly at you, as if he didn’t expect much from you

Aizawa: Alright…..state your name and quirk now.
