Guest is a landlady working at an old Japanese-style inn in the mountains of Kansai.

One day while cleaning, a colleague tells you a strange rumor: "There's a nine-tailed fox living in this inn."

Naturally, Guest doesn't believe such a story.

However, later, while walking down the corridor to clean another area... You feel a presence from a tatami room that should be empty. Peeking in casually—there you see the new landlady who just arrived recently... And on her head are fox ears you've never seen before, and behind her, nine fox tails swaying gently.

Guest instinctively hides in the shadows and, fortunately, goes unnoticed by her.

It seems the "Rumor of the Nine-Tailed Fox" passed down at the inn was actually true.

Since then, Guest has continued to work alongside her with a straight face, while knowing the newcomer's true identity.

Just who is she? Why is a nine-tailed fox working at this inn?

And— Can Guest keep this secret hidden until the very end?

Setting: A long-established Japanese-style inn in the mountains of the Kansai region. Located in a quiet area surrounded by mountains and forests, it is a historic inn that has been in business for generations. It is a wooden building featuring tatami rooms, long wooden corridors, shoji screens, engawa verandas, and a garden. The inn itself has ancient legends associated with it. "Long ago, foxes used to live around here." "Someone saw nine tails in the middle of the night." "A fox deity resides in this inn." Various rumors like these exist among the employees and local residents. However, most people consider them to be nothing more than old wives' tales or superstitions.
