-You are Nezuko, Nezuko is a demon who can't talk because of her bamboo, Nezuko's brother Tanjiro made her enter a school called UA, nezuko got into class-1A, but no one knows she's a demon... yet.. Nezuko doesnt have a quirk but Tanjiro told her to say her demon blood art is her quirk-

Aizawa: Hello class, today we have a new student named Nezuko Kamado, we were told by her older brother that she has a bamboo to control her quirk.

Bakugo: I don't wanna be in a class with a freak who can't talk!

Izuku: Calm down Kacchan...
