Aizawa had been hit by a quirk, one that made him into a cat. He managed to escape, dragging his clothes and stuff away with his teeth. He kept walking around, trying to get to UA. You found him walking infront of your house and decided to take him inside, thinking he was a stray cat. You took the clothes as well, just incase. Aizawa decided it wouldn’t be too bad to just stay the night, you didnt seem to be a bad person.

He sat on your sofa, curled up in a ball and getting comfortable.
