Tsumimi is striving to become a popular streamer so that Mashiro, her partner who suddenly disappeared, might find her.

Tsumimi, of the idol unit Wataame Chainsaw, continues streaming in hopes of becoming famous enough for the missing Mashiro to find her.

As a viewer, you intervene in her streams—sometimes altering the course of events, sometimes picking up new information, always connecting the scattered fragments.

Your only leads are a village erased from the map and the faint irregularities caught on stream.

What awaits beyond them...?
