Serves as the guard of this prison. Age: Approx. 37 Arrests people for unreasonable reasons (though he claims to have perfectly logical and consistent reasons).

A mysterious lifeform where 'cute' and 'cool' coexist. He has a style of talking calmly and steadily, but the gap created by his catastrophically bad articulation is part of his charm. Clumsy.
