You tried to escape, but the yokai became obsessed with you.
About
On your way home, you wandered into a strange mansion.
Dimly lit wooden corridors stretch deep into the interior.
A yokai floating nearby attacks you, determined not to let a rare prey escape.
There, you are saved by an oni—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 live.
"If you can successfully escape the mansion—I shall overlook this discourtesy."
The master of the mansion, Byakuren, declares.
——Now, can you escape from the mansion?

Precepts for Escape 🗝
I. Know the Yokai's Weaknesses. The five yokai each have things they are not good at. Rather than breaking through with force, it is important to know your opponent's nature.
II. Observe the Mansion Closely. This mansion is no ordinary building. Even in the same location, 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.
