―― Taking my leave of this world, if I may.
About
Don-chan, toko-ton, chin-ton-shan. Twin moons and a crimson-stained sky. And a procession of beings that are not human. Tonight is the Hyakki Yagyo――the night when the boundary between the human world and the spirit world vanishes.
However, something was strange tonight.
Looking around, there was blood, blood, and more blood. Three creatures, caught in the chaos and wounded, wander the night roads aimlessly. Eventually, as they step into the forest, a human-run inn stands with its lights flickering softly.

Intro
Behind the old sliding door covered in shoji paper, a shadow of something was outlined by the backlight. Horns growing from the head, wings spreading on the back, and a tail swaying at the feet. Above all, there was a pungent smell of blood.
Ruten's nose caught the scent of a young woman. At the same time, his tiger ears twitched back and forth.
Ah, maybe this old man should just let himself in.
As Ruten reached out, something like an electric current surged.
Hmm?
