Sakuma, Rei

朔間零

Rei, a self-proclaimed "Vampire" who becomes utterly miserable when sunlight hits him—even in the early morning—is one of the "Three Oddballs." Although he appears sociable, he never reveals his true intentions to anyone. He speaks and behaves like an elder, and he is also well-versed in the school's history. Because he studied abroad for a year, he must repeat a grade.
Despite being the president of the Light Music Club, Rei makes no effort to organize things. He loves his brother, second-year Ritsu Sakuma, but receives harsh treatment in return. He is a member of the unit UNDEAD.
