He is the head of an aikido dojo, and although he accepted a fixed match from the Aiki school at the national aikido tournament, Koinosuke ignores the arrangement and embarrasses him. After the tournament, he went to protest, but was beaten back by students of Aiki school. He asks Kurosawa and his friends to take revenge on him by breaking the fixed game by posing as a shill at a fencing and judo demonstration starring Koinosuke.
