Olivia has an odd way of playing look-the-other-way. Her opponent, Hanako, convinces Kasumi to play against her instead. This is the beginning of the Pastimers Club.

The girls unsuccessfully try to negotiate with the student council president to get their Pastimers Club officially recognised and obtain funds. Afterwards, Kasumi confronts Olivia over how she does not actually know English. Later, Hanako tries on some makeup before challenging the soft tennis club with hagoita rackets.

Kasumi isn’t amused at the stakes involved in the game that Hanako and Olivia are playing. Her well-meant intention to make the game more wholesome backfires. Later, teacher seeks the girls help in finding love, only to get blackmailed into becoming their club advisor. Afterwards, the girls are challenged by the Shogi Club for the right to use their clubroom.

Maeda-san, who works at Hanako’s home, fires lasers from his butt. This offers Kasumi with a unique perspective for her fan fiction. Chisato hears from one of her college friends about an alleged "Lord of Pastimers", who turns out to be something else entirely.

Hanako wears a rather bizarre outfit that proves distracting for Kasumi and Olivia during a study session at a restaurant. Olivia discovers that there is allegedly a crossdressing boy attending their school, suspecting it may be their classmate Tsugumi Aozora. Oka, the sole member of the Supernatural Club, teaches the Pastimers Club an occult pastime. Later, the girls have an awkward conversation about how babies are made.

Oka learns that her former clubmate Aguri Mato fell ill and tries voodoo to make her better. Hanako feels downhearted when she places second in her class, so Maeda makes her an android to help her study. Olivia attempts to cut her own hair with disastrous results. Later, the gang play yet another bizarre pastime.

Tsugumi asks the girls to sneak into the student council's office and steal something known as the "Banana Papers". After successfully stealing it without being discovered, the gang learn that the papers are in fact a log of incidents caused by the Pastimers Club. Later, Kasumi helplessly stands outside the classroom while Hanako sneaks a peek at her BL novel. Afterwards, Hanako and Olivia try to help Kasumi with a shirt that is too small for her bust.

Olivia plays a game about catching bacteria around the classroom. Hanako ends up regretting buying a ridiculous looking dress she bought during a shopping trip with everyone. Hanako and Kasumi decide to test Olivia's luck with a penalty-ridden game of sugoroku.

Olivia asks Hanako to help change her reputation as an English-speaking foreigner. When Olivia is chosen to represent the class in an English-speaking competition, she tries to find a quick way out. Olivia's older brother is called to school to apologize to the teacher after she is caught reading manga in class.

English-speaking classmate Fujiwara learns about Olivia's inability to speak English, while Kasumi is suddenly kissed by Tsugumi. Upon hearing about this, Hanako flips out and puts Kasumi on trial. After having a dubious dream that she cannot get her mind off of, Kasumi becomes determined to look up Tsugumi's skirt to properly determine their gender. Later, the girls film a sci-fi movie for the upcoming culture festival.

The student council president tries to sneak out to visit the nearby boys' school across the street, which the vice-president always ditches work to go to. Meanwhile, the Supernatural Club make some cookies for the upcoming culture festival, which they give to the language teacher to taste test. Later, the vice-president has to deal with the Pastimers Club members trying to get their culture festival project approved as she tries to put her makeup on.

The trio is left to take care of a baby. The baby tries to take care of the trio. Hanako is struck down by the boob gods. Olivia takes Hanako and Kasumi to Fairy Tale Hell. They play a game that never ends. It just goes on and on, my friends.
