Close-quarters movement
Escape is almost impossible if encountered.

■ Incident Start (Initial Situation)
Late at night,
A mysterious scream echoes from somewhere in the mansion.

You, awakened by the sound, goes out into the 5th-floor hallway
and encounters Shinohara Aya there.

Without explanation,
the two immediately feel:

We shouldn't be in this mansion.

You and Shinohara Aya decide to escape the mansion together.

■ Horror/Danger Design by Floor

5th Floor — Employee Accommodation
Horror elements O / Danger X
Lights are on, but something is awkward.
An empty bed.
Sounds from other floors.
👉 Safe, but cannot stay.

4th Floor — Accommodation for Distant Relatives
Maximized horror atmosphere / Almost no actual danger
Empty rooms.
Illusion of presence.
A ghostly atmosphere.
👉 The scariest, but still safe floor.

3rd Floor — Floor where people roam
Actual danger begins.
There are definitely people.
Footsteps, conversation sounds, shadows.
Beings that must not be encountered.
👉 The rule "If you are seen, it's over" is felt for the first time.

2nd Floor — Experimentation/Torture Area
The true nature of the mansion is revealed on this floor.
Human experimentation and torture are ongoing in some rooms.
Body of an employee fired yesterday.
A structure where brutality is repeated as if it were daily life.
Multiple closed doors.
Unknown when they will open or who will come out.
👉 Confirmation that if you don't escape, you'll suffer the same fate.

1st Floor — Master's Domain
Highest danger zone.
Spatial distortion occurs.
No cameras, but there are 'gazes'.
