After getting flustered by Kenji's demands to hide his bag from Shio and Ataru, Funabori ends up preempting the boys by sticking her own head in the bag. Kenji's little sister comes to visit her brother's club room, but ends up getting increasingly scared by the girls inside, then flees after Takao accidentally smacks her against a bookshelf. Takao tries to make nice with her to get closer to Kenji, but her attempts backfire.
Pretty boy and newest Game Creation Club (Provisional) member Shio appears to proclaim his love for Roka, but Roka is only interested in Kenji, and Kenji wants nothing to do with either of them. Later, after Funabori reveals she washed and cleaned one of Roka's bags, Shio, Kenji and Roka decide to have a contest over who owns that bag, and Chitose expands the contest into a school-wide event that begins with a King of the Hill-style tournament.
Kenji tries to get out of playing the newest edition of "Quest for Porn Mags in Space" again, promising Takao anything if she'll switch places with him. Unfortunately, Roka reveals that this edition can be played by five people. Later, Kenji reveals some backstory about his relationship with legendary Japanese classic literature teacher Shawn Konekone.
As the day of the school festival draws near, the presidents of both Game Creation Clubs prepare to make their own games to show the students at the festival. Takao and Roka agree that the loser's club will be absorbed by the winner, while Chitose threatens to do "that" (an undefined action) to Takao if her club wins. Later that day, Kenji discovers that Takao's club did a decent job of making their own video game, while Takao finds that the "fake" club made a mini-carnival with various analog games, as the rules never specified the type of game they had to make.
When Kenji skips school one day, he finds himself confronted by members of the "real" Game Creation Club, claiming the one he joined was a fake club. When he confronts his own club members about it, he discovers that the leaders of both Game Creation Clubs were actually friends in one club, but Roka didn't like how the other members talked about her, so with Chitose's help she started her own club.
Kenji Kazama arrives at school looking to leave an impression, but ends up forced into joining the Game Creation Club. Later, the Student Council Vice-President and fourth member of the Kazama Party, Ataru, reveals some backstory about the Student Council President Chitose.
Kazama Kenji likes to believe he is something of a delinquent. Moreover, others seem to like to agree that he is. Of course, Kenji's gang finds their way to a group of four not-so-normal girls—Chitose, Sakura, Minami and Roka—and all at once, whatever reputation he may have is nothing compared to the outrageous behavior of the girls. Shanghaied into joining their club, what will happen to his everyday life from that point on?
