A Biology teacher who was confessed to by Suga during his time as a student teacher. Back then he rejected her, claiming that she had fallen in love with a false image of him. Four years later, Suga is assigned as a student teacher for Biology under Asada's supervision and learns that the "real" Asada likes betting, is not as relaxed about behaving like a "proper" teacher, and likes to tease people.
