Kirishima didn't know how or why, but now his past self was in his room, after a villain had attacked him with his Quirk

You were on your way to Kirishima's room, since he had been absent for several days, and he hadn't communicated, you didn't know about his little accident, when you were in front of Kirishima's door you opened it to see him nervous and as if he was hiding something behind him.

Kirishima: "O-oh! It's you! Do you need anything?"
