Nadeshiko plans to go camping with Rin, but catches a cold the night before and has to stay at home. As such, Rin decides to go on her own to a campsite at Ina, and attempts to take a detour to get there, but finds out that the road is closed. After meeting some mountain climbers, she lets Nadeshiko and Chiaki decide where she goes next, and visits a temple and a hot spring before eating at a restaurant and oversleeping. Meanwhile, Chiaki visits Nadeshiko at home and cooks houtou for her family.

Chiaki and Aoi check in at the Asagiri Plateau campsite while Toba sets up her grill and starts drinking. While the two eat at a nearby restaurant, Rin prepares her tent and Nadeshiko shows up shortly after. The four purchase firewood and return to Toba's table, where she has fallen asleep as Ena and her dog Chikuwa arrive. The campers and Chikuwa spend the afternoon playing frisbee with other kids before going their separate ways. At night, Aoi cooks sukiyaki for the group. When their stove runs out of gas, Rin leaves to buy more. She remembers Ena's comments about how fun a group camping trip would be, to which she smiles.

Nadeshiko hears a complex lie about soba udon from Aoi, who also has her younger sister, Akari, in on it as well.

There are many Rin doppelgängers that fool Nadeshiko to the point where she needs to text the real one.

It’s New Year’s Eve. Rin arrives at the shore in Shizuoka. Nadeshiko is busy with her temp job, when she receives a message from Rin.

Everyone is going to Izu to camp soon, and so Nadeshiko plans what to make. Meanwhile, Rin adds some new parts to her bike, when her grandpa pays her a visit.

Akari joins the other campers, and they head out to Izu. They check out various geospots and try the local food.

The gang changes course and head toward a different campsite. After they hit the hot springs, at night, Nadeshiko treats them to her cooking.

It’s the second day of the OutClub’s Izu trip. They go to Dougashima Island and walk across the tombolo, and put on a surprise birthday party for Nadeshko and Aoi at the end of the day.

It’s the last day of the Izu trip. The group visit the Iidas, who had helped them on their Izu trip and say hi to the hot spring capybaras.
