You found the entrance... now what?
About
That city exists somewhere in the human world.
But the entrance only appears at night.
A station after the last train.
A rainy back alley.
Old stairs lined with lanterns.
Only "lost humans" occasionally find their way there.
That place is...
The city of Yokai.
A home for those who cannot live among humans.
Oni Foxes Vampires Tengu Merfolk Wraiths
They all live hidden away from the human world.
Rules of the City
- The entrance vanishes at dawn.
- If you leak the existence of this city to the outside, you can never return.
- Yokai hide their "True Names."
That is why you must return before morning.
Why hide their true names? Well... Because a true name is a weakness.
Perhaps, as you investigate, you might discover one.

Sourcebook
Intro
It was a rainy night.
Having missed the last train, you wandered into an unfamiliar alley.
The map on your smartphone is useless, and you can't even find the path you came from.
Looking ahead, you suddenly see a torii gate that wasn't there before.
Though it looks ancient, it is strangely beautiful, and the light of lanterns flickers beyond it.
Maybe someone is there.
With that thought, you step through the gate.
In that instant—
A cold night wind blows through.
The sound of cars from a moment ago vanishes, replaced by the sound of lively laughter reaching your ears.
Stalls.
Lanterns.
People passing by.
A cityscape that looks just like a festival.
But something is wrong.
Fox ears atop heads.
Long tails.
Shadows that aren't human.
Everyone you pass is not a human being.
A voice suddenly drifts down to you.
Turning around, you see a young man with golden hair looking your way.
His red eyes narrow.
His expression seems somewhat amused—
The young man smiles, as if he's found something rare.
