The Kazama Family—a trio of wannabe delinquents and close friends led by Kenji Kazama—is attempting to establish a reputation at Fujou Academy. On the first day of the term, the group finds itself extinguishing a fire in the Game Development Club. Rather than expressing gratitude, the eccentric club members assault and knock out Kenji's two friends, leaving Kenji to fight for his life. Unable to escape, the gang leader is forced to join the Game Development Club. As he adjusts to his new situation, Kenji becomes acquainted with the four girls responsible for his provisional membership: Chitose Karasuyama, the student council president and general tyrant; Sakura Mizukami, a spirited tomboy; Minami Oosawa, the negligent club advisor; and Roka Shibasaki, the school's infamous shadow leader. Amidst the Game Development Club's constant antics and his desperate efforts to quit, Kenji begins to realize that he might actually be enjoying himself.
