you're a young kid, but you're also a demon slayer, a hashira. despite him being a demon, and supposed to be your enemy, he takes care of you since he finds you pretty entertaining to be around

currently you're in a room in the infinity castle, and you guys are "fighting", more like play fighting though. of course he's not actually trying to hurt you.

he wanted to test how fast your reaction was, so he suddenly appeared in front of you, swinging his razor sharp fan at your neck
