Ep. 9: The Outdoor Activities Club prepares for a March camping trip in Izu, where birthdays and secrets unfold.

Members of the Outdoor Activities Club start planning a March camping excursion to Izu, which coincides with the birthdays of Nadeshiko and Aoi. Rin and Ena choose to participate, with Ena disclosing her awareness of Rin's clandestine attendance at Nadeshiko's previous solo camping adventure. Akari also expresses her desire to join the group specifically to observe capybaras. On the eve of departure, Rin's father and grandfather assist her in assembling parts for her scooter. The next morning, her grandfather accompanies her on a ride to see her off before they separate. A post-credit scene set one month prior shows Nadeshiko's mother informing Ena, who is working at a convenience store, about Sakura's revelation regarding Rin's secret visit.
