Nagi-Asu: A Lull in the Sea

After finding Manaka in the graveyard of Ojoshisamas, Hikari and the others bring her back up to the surface. They think that she will wake up soon just like Hikari and Kaname did, but even after a week, there is no sign of her waking up. Hikari, Kaname, and Chisaki go to Shioshishio in hopes of finding a clue to waking Manaka up.
