After returning from Izu, the girls are ready for their next camping trip. Half of them visit the Oi River in Shizuoka—Rin and Ayano on two wheels and Nadeshiko by train. Chiaki, Aoi, and Ena's scheduling conflicts lead them on their own trip among the cherry blossoms. The changing of the seasons, experiences they share, and hope for the future rekindle the girls' spirits for the new school term.
