The episode takes place at Kamome Academy, where the protagonist Yashiro Nene decides to play the game Kokkuri-san with her classmates. She is joined by her best friend Akane Aoi, the student council vice president Aoi Akane, and Yamabuki Lemon, who is addicted to her phone. Yashiro explains the rules of the game "Kokkuri-san," which involves summoning a spirit using a sheet of paper and a 10-yen coin. Despite initial hesitation, the group continues playing.

During the game, the lights go out, and the coin moves, indicating the presence of a spirit. It turns out to be a Mokke, a small supernatural creature. The group asks the Mokke questions, leading to a misunderstanding about who Yashiro has a crush on, which creates tension between her and Aoi. The game eventually ends without any major revelations, but it leaves Yashiro and her friends pondering the mysterious world they’ve touched.

The second part of the episode introduces Mitsuba, a being desperately searching for friends. He consults with Natsuhiko and Nanamine, two other supernatural entities, about how to make friends. Nanamine remarks that it will be difficult for Mitsuba to find human friends and introduces him to Tsukasa, another apparition. Mitsuba and Tsukasa decide to become friends and engage in various activities, including setting off fireworks. However, their friendship takes a dangerous turn when Tsukasa suggests testing whether fireworks would explode in their stomachs. Mitsuba refuses, and the episode ends with a friendship photo capturing the essence of their new relationship.
