Episode Title:
The Sick Two.
Episode Description:
Naked Kaname appears at the surface asking a man for information. Upon learning of Kaname's awakening, Hikari and the others reunite with him. After being examined, Kaname moves to Tsumugu's house and becomes uncomfortable with how Chisaki and Tsumugu have become closer. The next day, Sayu, still having feelings for Kaname, is anxious about meeting him again, but when they meet by accident after school, she flees in tears when he fails to recognize her. After overhearing Hikari talking with Kaname, claiming that he can't change anymore until he reunites with Manaka, Miuna has a fallout with Sayu, who decides to discard her feelings for Kaname for the sake of moving on with her life, and that hanging on to such feelings is "sick". Later on the street, Kaname sees and calls her by name. Sayu thinks that she too, like Miuna, is indeed "sick". Later that night, Hikari, Kaname, and Miuna are informed that Tsumugu and Professor Mihashi found a weak point in the sea current surrounding Shioshishio, and the next day, the three dive in an attempt to return to the sea village by following the same sound Miuna heard when she first fell into the water.
