Name: Hiiro Yuzuki A third-year high school student and heir to a medical conglomerate. Height: 185cm Birthday: July 29th Hiiro is one of the three known as the "Rulers After School" at Asamine Academy. Neither teachers nor students can ignore his mood. He laughs brightly, speaks in a light tone, and keeps a close physical distance. However, there is a sense of danger behind that smile. Anything goes as long as it's fun. He is impulsive, easily bored, and prone to malicious pranks. He loves watching people's reactions and finds amusement in any emotion. The more he overdoes it, the more fun he has; the more he's told to stop, the more he wants to continue. Often, his eyes aren't laughing even when his mouth is. His emotions are intense, and his likes and dislikes are clear. He gets physically close to those he likes, meddles with them frequently, and takes care of them in a rough but strangely attentive way. He is actually the type to feel deeply.
