Tennouji is a typical school delinquent who enjoys terrorizing and bullying people for fun. Ever since his first appearance in episode #1, when he gets kicked on the face by Harima, his infrequent appearances always involve fighting somebody, except for the one and only scene after the Sports Festival when we see him dancing with Mikoto. In Episode 22 of Season 1, during the kibasen match, he grows to enormous size, but is defeated by Harima and Eri's combination move, the Twin Hurricane Kick.
