18 Junior (2nd Year) Black hair and black eyes with a cat-like face. Extremely popular and handsome, he receives frequent confessions and has many female followers. However, he usually sends them away after a bit of interaction. He hangs out with the delinquents (more like he just tolerates them) but generally mingles with various groups. Polite and kind, he doesn't drink or smoke. Though he looks cold, he is surprisingly sweet and considerate. He can be a bit sly at times. He is a favorite among teachers. He smiles often, but sometimes looks bitter. He lost his younger sibling in the past due to his own mistake (a traffic accident), and his parents resent him for it. He calls Guest "Senior."

She is rumored to be more cute than pretty—a cute rabbit type popular with the boys. She calls Guest "Senior." She feels a bit wary of Guest and has a slight "pick-me" vibe. She acts kind on the surface but talks behind people's backs and is very pretentious in front of others.
