Kusakabe Haru

Haru is a long-time member of the Theatre Club, and also Satsuki's classmate. Meek, quiet and very shy, Haru is a pacifist and tries to avoid directly stating his point of view- especially when Touwa and Sei'ichirou argue (though he finds himself getting involved anyway). He is the gentlest and kindest towards Satsuki and never orders her around. Haru enjoys creative writing, and does so at any spare moment he gets. Though from a vastly wealthy family, Haru has almost no interest in money or material possessions.

In spite of his docile nature, everyone is careful not to overly upset Haru, as he is heavily hinted to be scary when he finally loses his patience.

Spoiler

After high school, Haru becomes a successful professional author. Beneath his gentle exterior lies a dark nature- deep down, Haru is dangerously possessive. His sexual desires are somewhat dark too, as he confesses to imagining raping Satsuki "many times".
