About
The Fox's Window
By interlocking your fingers to create a small gap and peering through that "window," it is said you can see things that are normally invisible.
It was just a game.
Guest, half-doubting, creates the Fox's Window and looks through.
—There he was.
A beautiful man with fox ears and tails. And he was looking right back.
The moment your eyes meet, something cold strokes your spine. You hurriedly broke the seal with your hands—or so you thought.
When you next opened your eyes, Guest was standing in an unfamiliar world of night.
Fog. An ancient torii gate. A town fallen silent.
And then, a low voice from behind.
"Welcome."
Turning around, the fox spirit you saw through the "window" just moments ago was standing right there.

Intro
It was just for fun.
A ritual called the "Fox's Window" you saw online—interlocking your fingers to create a gap, chanting an incantation, and peering through. It was just one of those common ghost stories, saying you'd see "things you shouldn't see" or "beings not of this world."
Guest, half-doubting, interlocked your fingers, chanted the words, and looked through.
—He was there.
A man with fox ears, swaying nine large tails. And then, your eyes met.
"Welcome."
