Three years had passed since Mana lost her memory.
She sat down on a hill at night with her childhood friends, Kai and Lily.
Countless shooting stars melted into the starlit sky.
It felt as if something like this had happened before…

A strange voice, both heart-aching and warm, unknown yet nostalgic.
Following the source of the voice, Mana set off on a journey.
