The Outdoor Activities Club gathers to discuss what it means to be a true Yamanashi local. Nadeshiko Kagamihara, Aoi Inuyama, and Chiaki Oogaki are part of the conversation, and Chiaki brings up an exciting event called the Yamanashi Kids' Stamp Rally, which Nadeshiko knows nothing about. The rally involves visiting popular destinations in the area and collecting stamps, with winners receiving a year's supply of delicious Minobu steamed buns. Nadeshiko is intrigued and keen to participate, leading the Club on a journey through Yamanashi to get their stamps while embracing the local customs.
