Leading a gang with the same name, Kenji Kazama is determined to take over Fujou High and cement his legacy. However, his first foray into deviant behavior results in his forced enrollment into the Game Development Club. There, he encounters four unusual girls: the strict student council president Chitose Karasuyama, indifferent club advisor Minami Oosawa, effervescent first-year student Sakura Mizukami, and tiny club president and covert school bully Roka Shibasaki. They all work hard to keep Kenji in the club and prevent its dissolution due to insufficient membership.
Despite Kenji’s overwhelming desire to break free, his actions only further entangle him in the club’s activities – and the antics of their equally bizarre adversaries. Curiously, Kenji remains oblivious to his growing enjoyment and the thrill of the club’s mischief.
