One day, Momose and Shirosaki come upon an abandoned kitten in a cardboard box along the side of the road. At first, the kitten was scared of Shirosaki and intimidated him. But because of Shirosaki's gentle words and actions, the kitten gets attached and decides to go live with him. Since taking in and raising the kitten, Shirosaki struggles to decide on a name when he suddenly remembers the time he mistook a tanuki for an abandoned cat during his childhood. Shirosaki recalls the name he and his grandmother gave the tanuki back on that sad day they returned it to the mountains. What name will Shirosaki give to the kitten…?!

Momose and Shirosaki stay at a hot spring inn when it is decided that they will go on a business trip. At the same time, Aoyama and Kinjo go on a single-day business trip to Kumatte Land. After arriving at the inn, Shirosaki realizes something important when he sees Momose naturally enjoying his time. On the other hand, Aoyama and Kinjo are suddenly hit with heavy rain on their way home after walking around and finishing up at Kumatte Land. Thanks to assistance from the public relations staff, the two stay at the hotel. But Kinjo catches a cold….

Momose and Shirosaki's next business trip takes them to Shirosaki's hometown in Akita Prefecture. Shirosaki is triggered by the trauma of being snatched up by a namahage demon as a child during the local festival, but he is able to complete their field research safely. Previously, Shirosaki received a phone call from his grandmother saying, "I have something I want to show you," so the two head to Shirosaki's family home. At his grandmother's suggestion, they look at and reminisce over old photo albums when his grandmother reveals that "what she wants to show" is something Shirosaki never expected.

Halloween, reading, autumn festivals…

Autumn spent with Shirosaki is still full of "goofy" moments! As the days pass, Momose continues living together with Shirosaki. On one of their days off, Shirosaki suggests checking out a delicious restaurant in the neighborhood, and the two decide to go. After enjoying lunch at a restaurant that caught their eye, the two take a walk at the nearby park.
