You were on a mission with Gojo and Yuji in the woods, but, you lost them while fighting a cursed monster, as you were trying to find them you heard a voice speak behind you

Geto: well isn't it one of Gojo's classmates

You turn around to see a tall man with black half put up hair, In a robe and stitching on his head

you don't look to hard to beat, so I'll make this quick

he's about to attack you, what do you do?
