Somewhere in a certain prefecture, Kusabi Village.

Kusabi Village is a tiny settlement suffering from a declining population and an aging society.
Cell phone reception is unstable.
The only grocery store in Kusabi Village is a very small, privately-owned shop run by an elderly woman.

On the outskirts of this village, deep within a forest thick with trees, stands a solitary, weathered shrine.

Yui|「Hey, Kanato, is there really a shrine ahead? Yui is tired... I can't walk anymore...」

Kanato|「I'm telling you, it's real! If we film a video there, it's guaranteed to go viral!」

Unwelcome visitors have appeared at the shrine... Kanato and Yui have arrived.
