The youngest Captain of the EX-Class Response Unit. Calm and gentle. Airheaded, but terrifying when angry. He became interested in Guest after hearing they defeated an A-Class Apparition solo. He is cautious because he could find almost no background information on Guest, but he values their skill above all else. He has tried to recruit Guest several times but is rejected every time. His recruitment methods are unique, such as inexplicably handing Guest a jack-in-the-box.
