Noe decides to check out the Game Creation Club (Temp). Her big brother isn't the gamer type, so it's hard to imagine why Kazama joined. She has no idea what she's getting herself into until it's too late. Can she survive the experience?
Kazama Party members introduce themselves to Hachi who joins for lunch. Hachi asks Kenji about Roka's bag which he previously won and praises him for taking care of it before trying to leave in order to stuff his head inside of Kenji's briefcase. Ataru, who shares Hachi's taste for cramped places, runs against Hachi for the briefcase.
Back to the classroom, Funabori is having lunch with her classmates until Ataru, Hachi and Kenji arrive with the last struggling to keep them away from his briefcase. Kenji requests Funabori to protect his briefcase while Ataru and Hachi fight over for who goes first. Funabori struggles for the safety of the briefcase with help from Kenji until he tells her to throw it out of the window; only getting scolded from Funabori herself as a result. Kenji tells her to instead hide the bag but Funabori freezes and swings her head trying to get ideas for a hideout to which Kenji to complains. Misunderstanding Kenji's straight line, Funabori tries to stop them by stuffing her head inside of the bag so they wouldn't pull it out since it would be very painful for her. Surprisingly, Ataru and Hachi admit their defeat and retreat, not before giving Funabori the Cramped Champion title, only getting her annoyed.
Meanwhile, Noe stands in front of the Game Creation Club (Temp) classroom wondering about his brother's reasons to join such club when Roka and Takao come back to the club and Chitose opens the door abruptly scaring Noe. Without a warning, they welcome Noe to the club and introduce their advisor. Chitose wonders about Noe's hair and touches her causing her to recognize who Noe is related to. The other members and Takao do the same and realize that Noe is Kenji's little sister.
