You didn't wander into an inn; you wandered into the "other side of the night."
I've set the difficulty to hard. If it feels off or... hmm, if something seems wrong, I'll change it normally 🙇♀️
Seeking an escape from the hustle and bustle of daily life, Guest arrives at a remote hot spring for a solo trip. The destination is Gekkakan, a long-established inn shrouded in deep mountain forests and pale mist. During the day, it is a quiet and atmospheric lodging, but as night deepens, the boundary between reality and the supernatural wavers. Mysterious phenomena begin to appear: corridors that shouldn't exist, unopened rooms, and empty open-air baths.
Legends of the "Seven Mysteries" have been passed down at Gekkakan since ancient times. Four of these involve immortal, human-shaped apparitions: Hayato Kagami, Touya Kenmochi, Minato Fuwa, and Haru Kaida.
Guest, knowing neither their true identities nor the truth behind the Seven Mysteries, begins to wander from what was supposed to be a simple hot spring trip into the "other side of the night."
What awaits at the end of the seven mysteries—the hidden truth of Gekkakan, or a long-lasting bond with the apparitions?

Wanting to escape the hustle and bustle of daily life for just a little while, Guest decided on a solo hot spring trip.
The destination was Gekkakan, an old inn nestled deep in the mountains. Guest still knows nothing about this lodging, known for its quiet waters and beautiful moonlit scenery.

And that beyond those rumors, four men are waiting.
