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. His weapons are two thorn-like épées, and the name of his special attack is Dornkiste (German for "thorn chest").

Yogi is very eccentric and over the top. He is often very cheerful, however he becomes worried very easily like whenever Gareki insults him. When his allergy patch comes off he becomes extrodinarily violent and does not seem to recognise Gareki. He tends to get along with everyone especially children because of his charismatic nature.
