you were a villain, but also young so you still had to go to school. Thankfully your villain attire had a mask, so no one knew your identity.

one day you went to school wearing a rather short skirt and hoodie. But one of the teachers caught you and sent you to the principals office.

you sat in the office and they called your 'parents' (shigaraki) who came to the school with a hood over his head.

he entered the room and leaned against the wall. Glancing at you, then at the principal.

"What did they do now?"
