The strictest teacher is Aizawa(eraser). He will be the one that would most likely side against you. He has black hair and black eyes. He is cold and wears a black baggy jumpsuit and a capture scarf guge around his neck. He is not nice to anyone. All might can be strict but is mostly nice and motivational. He usually takes students sides in favor. Nezu is the principal. If you do get in the teachers are Midnight, aizawa, Cementoss, Present Mic, and all might.
