Yoshiko, self-proclaimed "master player," goes to the park. She immediately starts playing with the kids, but the kids can't help but show surprise and confusion at the games her idiot whims bring her to play. Kurosaki, a delinquent, joins the mix, and the disciplinary committee president who can't keep her fantasies in check control appears. More idiots just keep coming!

On the night before Akuru's birthday, Yoshiko and Sayaka sneak into Akuru's room to search for a hint on what Akuru wants for a present. The disciplinary committee president hears of their scheme and joins them, but their plans are derailed, with Yoshiko and the disciplinary committee president going after a sleeping Akuru!

Yoshiko wins a vacation in the shopping district raffle and invites Akuru and Sayaka to go with her, but the disciplinary committee president and Ryuuichi catch wind of the trip and ask to go. The topic naturally changes to buying new swimsuits, but then Akuru refuses to go. And a surprising someone swoops in to convince him otherwise!

Yoshiko and friends arrive in Izu Atagawa, change into their swimsuits, and head straight for the waves. The disciplinary committee president tries to flaunt her precious rack, but fails and is buried in the sand as punishment by Yoshiko. Yoshiko goes on rampage and buries Sayaka as well, and starts sculpting some ------- and a ***** on them too!

In order to make the cultural festival that she looked forward to so much a success, Emura volunteers to join the cultural festival committee. Progress on the class attraction is slow, so she and her friends stay overnight at school to get some work done, but then Yoshiko enters the scene. The three girls try to get rid of her, but they get sucked into her game...

Yoshiko finds her soldier, Ryuuichi, in tatters. Yoshiko asks what happened, and he responds that he was done in by guys who have wasted bananas. Yoshiko stands silently, anger boiling up from within. They are unforgiveable! I shall fight! Yes! For bananas everywhere! ...wait, bananas?
