As the years progress, Rin Shima, Nadeshiko Kagamihara and their companions have matured into full adults. With jobs and obligations, they can no longer freely spend days exploring and camping. Yet Chiaki Oogaki, employed by the Yamanashi Tourism Board, reunites the circle with an enticing idea—to construct a campground on a neglected plot in their native Yamanashi Prefecture, breathing new life into it in the serene mountains. Driven by this bold venture, the women unite their talents to forge a setting where future generations can relish distinctive moments as they once did, while recalling the allure of high‑school camping adventures for those who cherish nature and adventure today.
