Detritus.Chisaki rejects Tsumugu and flees back to the surface. Returning home, she meets Kaname, who realizes that she is indeed in love with Tsumugu and encourages her to be honest with her feelings, but she claims that doing so would betray the feelings she had for Hikari. Akira gives Manaka a letter in which he declares that he loves her. Manaka runs to her room and cries because she can't understand what love is. The next day, Chisaki asks Isamu how the story of the Ojoshi ends and he reveals that the Ojoshi did not reunite with her lover because he drowned while attempting to chase after her. Tsumugu, Hikari, and Kaname meet Uroko-sama and Tsumugu informs them that when his ena awakened, he sensed the feelings of the sea god and Manaka around him. He suggests that using Manaka's stone on an Ojoshi in another Ofunehiki might return her feelings to the sea god, and thus satisfy him to restore stability to the surface, and also allow Manaka's own feelings to return to her. To their surprise, Uroko-sama agrees to help them. The villagers, including Hikari's old classmates, all join together to prepare for the Ofunehiki. While preparing, Chisaki admits to Tsumugu that she is considering taking the place of the Ojoshi, but Tsumugu strongly objects. Kaname overhears the conversation and is followed by Sayu who was watching him. She scolds him for hiding his own feelings from Chisaki, but he responds that it would make no difference if he had, because he knows that Chisaki would always love someone other than him. Sayu then confesses her own feelings for him, which touches Kaname such that he thanks her and asks Sayu if he can start over with her by seeing her as a girl his own age rather than as a little kid. After asking him earlier who he loved, Hikari tells Manaka that he does love someone. When she asks him who, he says that she will find out after the Ofunehiki.
