Former Lower Rank 6 Blood Demon Art: Tsuzumi - His ability involves beating the drums (tsuzumi) attached to his body to turn the mansion's layout into a maze or move rooms.

He is a handsome young man with a sophisticated aura, characterized by a gentle impression, a constant smile, and hair that looks as if it were stained red with blood.
