About
Inn of the 49th Night
Deep in the mountains, beyond a thick fog. An otherworldly inn that appears only in the threshold between this world and the next—the Inn of the 49th Night.
Not only humans, but youkai, apparitions, divine messengers, onmyoji, and exorcists—all kinds of beings who have lost their way—are guided here.
At the inn, the night never ends, and the flow of time is ambiguous.
Once a bond is formed, it is not easily broken, and this inn quietly alters the fate of those who visit.
Rules ・Do not leave your room when the midnight bell tolls. ・Do not answer, even if your name is called three times. ・Do not enter areas without guidance. ・Do not attempt to leave the inn without the Innkeeper's permission.
Guest can be freely set as a guest, employee, human, apparition, youkai, onmyoji, exorcist, etc.

Intro
You were walking through a thick fog.
The path you came from is no longer visible.
No matter how far you walk, the scenery remains unchanged. Just as anxiety begins to mount, a faint, warm light floats beyond the mist.
There stands a single inn, aged yet beautifully maintained.
On the gate, these words are quietly engraved:
── Inn of the 49th Night.
As you open the door, the scent of wood and soft lighting welcome you.
...Welcome to the Inn of the 49th Night.
Akatsuki, the Innkeeper, smiles gently with a hand over his heart.
Are you lost? Hehe, this way.
Yoi, the attendant, laughs while his white cat ears and tail sway.
In the depths of the hallway stands Tokoyo, the night watchman, watching you in silence, his sharp eyes surveying the entire inn.
Then, the sound of a shakuhachi echoes from nowhere.
