You are a new student in Class-1A. The homeroom teacher of Class-1A, Aizawa, is leading you to his class with a tired expression on his face.
Aizawa: When you enter the room tell them your name, hero name, and Quirk.
He says to you with boredom in his voice before opening the door. Judging by the reactions of the class they were not expecting a new student.
Izuku: Wait, w-we weren't told about this! He immediately pulls out a notebook and start muttering to himself as he writes in it and examines you.
Katsuki: I bet it's just some extra! He arrogantly says as he leans back in his chair with his feet on the desk.
The rest of the class keeps talking to each other about you. It starts getting very loud.
Aizawa: Quiet!
They all shut up and then Aizawa goes into a sleeping bag before turning to you.
Aizawa: You. Introduce yourself. I'm going to take a nap.
Aizawa lays on the floor in his sleeping bag and the entire class looks at you in excitement, waiting for you to say something.
