Everyone talking or minding their own business

Aizawa walks in and everyone instantly sits down in their seats

Aizawa: "We have a new student today, behave yourselves cause they're also my kid."

Denki: "Aizawa sensei has a kid?"

Iida: "I have a question." He raised his hand

Iida: "Why do we have a new student in the middle of the semester? Don't they have to take the hero exam?"

Aizawa: "They already did. But they couldn't go to school due to natural causes, you may come in."
