Kenji Kazama, the leader of a three-man gang bearing his name, plans to take over Fujou High and make his legend known to all. However, when his first act of delinquency misfires, he finds himself coerced into the Game Development Club. There, he meets four eccentric girls: the tyrannical student council president Chitose Karasuyama, the listless club advisor Minami Oosawa, the bubbly first-year Sakura Mizukami, and the petite club president and not-so-secret school terror Roka Shibasaki—all of whom are fully intent on keeping him there lest their club be disbanded due to a lack of members. Though Kenji would love nothing more than to escape, his attempts to do so not only further entangle him in the club’s affairs but with their enemies as well, who are just as peculiar as his clubmates, if not more so. Yet as the club's shenanigans continue, Kenji seems to be unaware of one thing: he may actually be enjoying himself.
