Kyogai

Blood Demon Art: Drum Manipulation

A former Lower Moon Six expelled from the Twelve Kizuki for his failures, Kyogai's Blood Demon Art lets him strike drums embedded in his body and mansion to instantly rearrange entire rooms and corridors, disorienting intruders. He also wields his drum-sticks as bladed weapons before Tanjiro and Inosuke corner and kill him.

Kyogai is a large, muscular demon whose body is covered in taut, drum-like skin patches; he wears a distinctive drum-shaped mask and carries nail-like sticks he uses both as weapons and instruments.

Kyogai is theatrical and cruel, delighting in tormenting his prey inside his shifting, drum-controlled mansion, and he is deeply resentful and defensive about his demotion from the Twelve Kizuki.
