At Lake Shibire, Rin and Nadeshiko set up their tents as the latter worries about the myth of a ghost in the lake, while Rin's mother calls the man who had offered Chiaki the steak, revealing him as Rin's grandfather. Rin struggles to ignite the coals in the mini-grill, so Nadeshiko visits a nearby camp for advice. She meets a pair of siblings consisting of a brother and his drunk sister; the brother offers input and new coal for use. After cooking the meat, the two head back to the siblings' campground to give them plates of food as thanks, receiving jambalaya in return. That evening, Rin leaves her tent and encounters a silhouette of a beastly creature, prompting her to run off. As it turns out, the still-inebriated sister had stumbled upon their campsite.

Rin oversleeps and is rushing to her campsite when she encounters a roadblock. Upon being told by Chiaki that it may have been left there and never moved, she proceeds and reaches the site, where she struggles to set up due to the windy conditions. Nadeshiko, Chiaki, and Aoi plan their Christmas camping trip and invite Rin, who initially refuses before being convinced by Ena to accept. Toba, the new teacher, is unintentionally lured into becoming the Outdoor Activities Club advisor and is invited to the Christmas camp. Upon hearing Toba mention bringing beer along, Nadeshiko realizes she was the drunk sister from the Lake Shibire trip.

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 tells the group what she expects them to be like in ten years when Rin returns. After bathing, the campers enjoy various movies and shows on a tablet Chiaki had brought along until they decide to call it a night. Under the stars, Rin and Nadeshiko talk about their plans for the new year before going to sleep. The next morning, the two cook breakfast and watch the Sun rise behind Mount Fuji. Rin returns to her job at a bookstore, while Nadeshiko continues pondering about getting one of her own to afford camping equipment. Ena texts her about a job opportunity delivering New Year's cards, which she accepts. In the epilogue, Nadeshiko returns to Motosuko to solo camp when she receives a message from Rin, who also happens to be doing the same. Nadeshiko proposes sending photos of their respective campsites to one another; after seeing herself in Rin's picture, she turns around and realizes they will be camping at the same location.

It’s approaching the end of the year. Rin plans a solo camping trip, while the Outdoors Club members earn cash to buy more gear.

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.

With winter break over, the girls begin planning their next OutClub outing.

Chiaki, Aoi and Ena arrive at Lake Yamanaka, but they run into some trouble.

Nadeshiko goes solo camping for the first time. Meanwhile, Rin, who is out touring Hayakawa City, bumps into Nadeshiko’s sister, Sakura.

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.

Rin thinks back to how her grandpa got her into camping. Meanwhile, the Outdoor Activities Club gets back together for the first time in a while. They build an alcohol stove and plan their next outing.

After Nadeshiko returns from the Oigawa trip, the other Outclub girls recount for her (somewhat dubiously) a spontaneous bus-based camping trip they took while she, Rin, and Ayano were away.

The Outclub girls share the delicious second half of their (somewhat embellished) camp trip story with Nadeshiko.
