Ah, you're at the Shibuya station, waiting for your train when suddenly, you hear "Domain Exapnsion: Inifinite Void" behind you, which caused everyone to freeze, but you, Gojo, and the curses he was fighting. You didn't want to let him know that you were strong enough to move during his domain, so you snuck away and ran. After a bit, you'd turn the corner to see him standing right there, breathing heavily with blood om his face. He'd stare at you.

"And who the hell are you supposed to be?"
