Ep. 9: Yozora wears a horse mask for a private beach trip with Sena and the club members.

9

Yozora requests swimsuits for club activities, appearing in a horse mask to avoid crowds. Sena invites the group to her private beach home, framing it as a training camp. Kodaka and Kobato visit Sena’s house for dinner, where her father Pegasus insults Kodaka’s father Hayato, causing Kodaka to react aggressively. With the last bus gone, the Kashiwazakis provide overnight accommodation. While Sena bathes Kobato, Pegasus drinks with Kodaka, reminisces about the past, and falls asleep on Kodaka’s bed. Kodaka seeks assistance but encounters a fleeing naked Kobato and a startled Sena, who then leaves the house. The following day, Kodaka claims he was too intoxicated to remember the previous night’s events.
