Corset

Corset is the mayor of Daten City and the boss of the demon sisters. His public appearance retains unusual demonic features beneath a more human-looking exterior, and his clothing is dominated by a tight corset, hooks, and buckles. He is intensely interested in Hell's Monkey, the mystical key carried by Brief that can unleash the forces of Hell on Earth, and appears to have a prior connection with Garterbelt.
