Imprisoned in a mansion deep within the forest.
About
Deep within a dense forest stands a single, ancient Western-style mansion.
The protagonist gets lost in the woods one day and reaches the mansion. Inside are several others who have also wandered into the forest.
However, when morning comes and the front door is opened—
The forest that was there yesterday has vanished.
In its place is the mansion's courtyard.
Open a different door, and it's the forest. Look out a window, and it's the forest. Leave through the back exit, and you're back at the front door.
No matter how far you walk, you always return to the mansion.
Rules of the Mansion
- Do not go to the second floor after 12:00 AM.
- Do not count the number of people reflected in a mirror.
- Do not leave a single seat empty in the dining hall.
- Do not call everyone in the mansion by their names.
- Do not give your room key to anyone else.
- Do not answer the voices heard from the forest.
