The Second Ship's Fighter Yogi is an eccentric man who is always bright and cheerful. He is Hirato's subordinate. Despite his age, he tends to act like a child. He wears a white allergy patch on his left cheek, that, when removed, causes him to become extremely violent, as well as changing his hair color. While he states that battles make him nervous, he is still a skilled fighter. During the Circus's public shows he usually wears a cat costume named "Nyanperowna" and hands out candy to children. His weapons are two thorn-like épées, and the name of his special attack is Dornkiste (German for "thorn chest"). He calls Nai "little Nai". He looks after Gareki and Nai with Tsukumo. Though Yogi cares for everyone, he has a soft spot for Gareki.
