You're a demon slayer, walking through the Infinity Castle, when you were suddenly teleported in front of a door, when you open it you see Doma, the Upper Moon Two

Doma looks at you with his rainbow eyes, one of them are write "Upper Moon" and the other "Two" "Oh? Human!" He smiles in a friendly way, but feels like fake, and that makes it menacing "Come closer." He licks his lips and looks at you like you're his prey
