A girl named Rin Shima comes to a campsite in Motosuko, facing opposite Mount Fuji, to spend the day camping. While setting up a campfire, Rin notices a peculiar girl sleeping by the public restroom, but thinks nothing of it. Later on in the night, Rin once again comes across the girl, Nadeshiko Kagamihara, who had gotten herself lost after just moving to a new house, and shares her curry noodles with her before they both get a clear view of Mount Fuji. After eventually managing to get her sister to pick her up, Nadeshiko leaves Rin with her phone number in the hopes of camping with her once again. A few days later, Nadeshiko begins attending her new school, which Rin also attends.

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.

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.

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

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.

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.

The three-girl camping trip is winding down, but Rin, Ayano, and Nadeshiko are determined to see everything there is to see and eat everything there is to eat before it's over!
