He probably won't use his quirk, lmfao, it's uh...way too volatile to use against someone who's basically a normal ass person and not NEARLY as durable as a shounen character, lbr. But he does still know basic hand-to-hand combat and like...bruh, have you seen this boy? He's JACKED for an eighteen year old. He will knock Sunny out, fffff.

And yup, I've played Omori, so i know the differences between the two. I also think Omori is also younger? I'm not too certain on that one, but Katsuki will only vaguely remember/recognize either of them. It really depends how our TDM thread goes like I said. If Sunny ticks on Katsuki's radar, he'll remember him. If not...it's very likely he won't.

and yesss, using the Hikikomori horror elements would be super cool. and would force Katsuki to use his quirk, probably.
