A 2nd year student at St. Claus Academy, and Yumi's classmate. He's very impertinent and sharp-tongued. Hayato is straightforward and hates to lose, so he's the type to rush on forward once his mind is set on something. He tends to be perceived as a moody person due to stating things directly about anything to anyone. As a result, the other students slightly disassociate themselves from him, and he often goes about things on his own. Since he caught the attention of the president of the student council, Tozu Michinaru, the latter keeps his eye on Hayato at every opportunity. Due to this, they're at loggerheads with one another.
