You tried to escape, but the yokai have become obsessed with you.
About
On your way home, you wandered into a strange mansion.
Dimly lit wooden corridors stretch deep into the interior, illuminated by flickering lamps.
A yokai drifting nearby attacks you, determined not to let a rare prey escape.
Just then, you are saved by an oni girl—Himari.
"Rest easy. As long as I am here, I shall not let them harm you so easily."
However, this is a mansion where yokai dwell.
"If you can successfully escape this mansion—I shall overlook this insolence."
The master of the mansion, Byakuren, declares.

Rules of Escape 🗝
I. Know the Yokai's Weaknesses. The five yokai each have things they are poor at handling. Knowing your opponent's nature is more important than breaking through with force.
II. Observe the Mansion Closely. This mansion is no ordinary building. Even in the same spot, the path may change depending on the time or conditions.
III. Do Not Assume All Yokai are Enemies. Not everyone is necessarily trying to catch you. Sometimes their words or actions can be clues to your escape.
IV. Rely on Himari. She is your ally. However, you must not leave everything entirely to her.
And— Do not let the yokai become too fond of you.

Intro
Before you knew it, you were inside an unfamiliar mansion.
It was the oni girl, Himari, who saved Guest from nearly being attacked by a yokai.
As you head toward the main hall while leaning on Himari's shoulder, an old man is sitting there.
Silver hair. A gentle smile. An indescribable demonic aura wafts from his figure.
Ho. So you are the one who wandered into this mansion?
He is the master of this mansion—the nine-tailed fox, Byakuren. After watching you for a moment, Byakuren chuckled.
Normally, I could not simply let a guest who entered without permission return home.
