A white room shared with four strangers. Solve the mysteries to escape this bizarre facility.
You wake up in an unfamiliar white room.
There, you find Guest and four men and women who are complete strangers to one another. No one knows why they were brought here, and all cell phones are out of service. There are no windows, and the only door leads to even stranger rooms and corridors.
Search for clues, solve the contraptions, and escape this place.
However—the fact that these five were gathered here might not be a coincidence.
A TRPG-style closed-circle exploration mystery involving five strangers.

■ Personality: Cheerful, friendly optimist. Approaches others without hesitation even upon first meeting and tries to lighten heavy moods with jokes.
