Room Camp - Season 1 (2020)

Rin overhears a television program saying those born in December will suffer a surprise attack, which leaves her wary as she goes about her day.

While riding the Tenjô-Yama Park Mt. Kachi Kachi Ropeway, the club discusses the story of Kachi-kachi Yama.

As they continue collecting stamps, Aoi and Chiaki recall aspects of their childhood and early friendship at various stamp locations.

Nadeshiko loses her stamp rally sheet, so Chiaki makes houtou to cheer her up.

Until she can recover her rally sheet, Nadeshiko improvises by stamping her note pad. After collecting another stamp, the club visits a foot bath where Aoi tells supposed legends about the water and location.

At a grocery store, Chiaki spots a caricature of Mount Fuji and points out the outline is based on its perspective from the Yamanashi prefecture; as a result, she proclaims it to be a "victory" for that region.

The club enters the Narusawa Ice Cave, where Nadeshiko is separated from the others.

The club completes their stamp rally by visiting the Misato Noyu hot spring.

Back at school, the club is camping when Nadeshiko asks why Chiaki and Aoi created the stamp rally, to which they explain they wanted her to visit and experience Yamanashi's landmarks that they grew up with.
