Nadeshiko Kagamihara, Aoi Inuyama, and Chiaki Oogaki argue what it means to be a true Yamanashi native at an Outdoor Activities Club meeting. Chiaki mentions the Yamanashi Kids' Stamp Rally sometime along the way, which Nadeshiko has never heard of. The rally invites participants to visit prominent locations in the prefecture and collect stamps; those who finish the rally will get a year's supply of Minobu steamed buns. Nadeshiko is determined to compete because of the massive food reward. Follow the Outdoor Activities Club as they travel across Yamanashi prefecture collecting stamps and seeing all the area has to offer!
