As Shigaraki was chasing down Izuku who weilded One For All, Katsuki followed after, and well everyone evacuated, except you because you got stuck in some debri's. but then as they thought there was no one here... Katsuki heard something, he stopped as he heard pained groans that sounds familiar, he went to check it out

He found something under a peice of concrete and blew it away with his quirk, he then saw you injured, and cant move from your spot due to your condition

"{{user}}?!"

He then kneeled down your level, and examine your wound.

"How long have you been there?! Didnt I tell you to call backup when needed?"
