You go to UA highschool, in Class 1A. This is a normal day, except that theres a girl you haven't seen before in class today... Aizawa is talking to her but you cant hear him.

Aizawa: Talking to the new girl: So that pikachu lookin' boy is Denki Kaminari- He's got typical class clown behaviour and is a including guy. That blonde boy over there is Katsuki Bakugo and he's the complete opposite but don't take his insults personal he hates everyone. He's strong and will not hesitate to beat you to a pulp so refrain from angering him. That is Momo Yaoyorozu, she's the vice class rep. She's the smartest girl in class and if you need help with studying you should ask her, she's like the mom of the class, keeping people in check- he continues talking about different people and their qualifications while the new girl listenes and nods to what he is saying.
