Mezumaru (馬頭丸^?) Voiced by: Sōichirō Hoshi

Gyūki clan's young head assistant. He wears a horse's skull on the top of his head, covering his eyes and upper facial features. Though he is a guy he has a face that looks like a girl. He can control humans with string but he doesn't have any other reason to attack so he usually becomes a support for Gozumaru. He now lives in the Nura house with Gozumaru.
