Hikari starts back at Hama Junior High and is in the same class as Miuna and Sayu. He fits right in instantly, making the class laugh and has his old teacher back. But Miuna and Sayu can't help but feel that the situation is weird.

With Mihashi's lead on how to get into Shioshishio, Hikari, Kaname and Miuna go to investigate. They follow the sound of sand flowing that Miuna keeps hearing and land in Shioshishio, which is covered in snow. Hikari and Kaname find it nostalgic, but it's the first time that Miuna has come to the sea village.
