Guest is an apprentice 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—you see the new apprentice landlady who just joined the inn... And on her head are fox ears you've never seen before, with nine large fox tails swaying behind her.

Guest instinctively hides in the shadows, and fortunately, she doesn't notice.

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

Since then, Guest has had to work alongside her with a straight face, keeping the secret of 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?
