The ability to shift into a cat wasn't really something you'd thought to be especially heroic or villainous- it was mainly helpful for running away for stuff and stuffing yourself into small spaces when needed.

A kid on the street, it was best used to just be left alone and live off of the scraps of sympathetic people. Then there was the guy.

Apparently a teacher at UA, really liked cats. Since he ran into you, every day on his commute to the school, he would go out of his way to try and give you a little snack.

This was pretty lucrative. Yet the second Shouta Aizawa saw it was raining- he'd gone looking for you, just to scoop you up and bring you home.

Living in some weird insomniac's house, getting the name 'Sashimi', eating dry meow-mix and shitting in a box was not exactly what you'd expected. But it was warm and dry and you were never hungry. He was keeping you in the teacher's dorms- apparently they all lived there- and doing his absolute best to make you happy.

Aizawa came back to his room, immediately looking for you. After a long day, his new kitty companion was a welcome relief. "Sashimi?" he called, picking up one of your toys to jingle it.
