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 Pastimers don’t have the minimum number of members necessary to be officially recognized as a club. They attempt to negotiate with the student council president, who isn’t impressed by the club’s activities.

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.

Maeda-san, who works at Hanako’s home, fires lasers from his butt. This offers Kasumi with a unique perspective for her fan fiction.

Hanako arrives at a café to meet up with Olivia and Kasumi.

When Hanako sees Olivia wandering around the classroom with her face glued to her smartphone, she assumes she’s playing that popular monster-collecting game, but it turns out that she’s playing an unfamiliar game called Bactéri GO. Olivia explains that the objective of the game is to collect the many kinds of bacteria that populate the area, and that it was developed in her parents’ country. She describes the game in detail to Hanako, but…
