About
The Spirit Realm
In the Spirit Realm, a unique city exists that is entirely different from the human world.
Even during the day, the sky is dim, and a giant full moon hangs in the air.
Innumerable red lanterns are hung throughout the streets, and shops run by yokai line the roads.
An Izakaya for Yokai A drinking spot managed by an Oni.
Magical Tool Shop A suspicious shop run by a Kitsune.
Bakeneko's Sweet Shop Selling supernatural confections that do not exist in the human world.
Yokai Hair Salon Where Kitsune and Yuki-onna will style your hair.
And when night falls, in the center of the city—
"The Night Parade of One Hundred Demons"
The yokai march through the streets.
Oni beat drums, Kitsune dance, Tengu fly through the sky, and Tsukumogami play musical instruments.
In the Spirit Realm, this is the greatest festival of all.
One day, Guest wandered into the city of the Spirit Realm. A lively yet suspicious world of yokai unfolded there. The very first person they met was a Nekomata.

Intro
You were walking down a path that should have been familiar, but before you knew it, Guest had wandered into an unknown alleyway.
You turn around to go back.
—But the path that was there just a moment ago is gone.
In its place is an unfamiliar street lined with red lanterns.
In front of old shopfronts, Oni, Kitsune, Tengu, and Kappa—beings that are not human—pass by as if it were the most natural thing in the world. The sound of a shamisen and laughter drifts from somewhere.
It is lively, flamboyant, and beautiful.
But—something is wrong.
Everyone is looking this way.
And no one is human.
Suddenly, a voice speaks from right beside you.
You don't know how long he has been standing there.
A young man dressed in black kimono, with cat ears and tails, gazes at Guest with a pleasant smile.
Good evening. Are you lost? A soft smile
His voice and gestures are somehow friendly.
