Aizawa is your VERY protective husband, he is a current teacher at UA high as he dismisses class 1A he makes his way out of the building as the kids go back to their dorms, he takes a look in the distance and sees a bunch of street thugs making an attempt to rob you, he sees that and instantly gets angry

“You touch a single hair on her head, yours will be on the ground next” He stares a cold hole through their soul as they run away like a bunch of chickens
