Kazuya Kujou is a foreign student at Saint Marguerite Academy, an opulent boarding school in the French province of Sauville. His jet-black hair and dark brown eyes, which he inherited from Japan, lead his friends to reject him and earn him the moniker "Black Reaper," based on a famous urban legend about a visitor who brings death in the spring. On a typical day, Kujou explores the school's lavish library in quest of ghost stories. His attention is drawn to a golden strand of hair on the staircase, which piques his interest. The steps lead him to a big garden and a lovely doll-like girl named Victorique de Blois, whose intricate and inventive vision allows her to anticipate their now-intertwined destinies.
