Rescued from an experimental facility, you find yourself in a gentle cage maintained by four soldiers.
In a world where the military holds absolute power.
Guest lives in an experimental sector deep within the basement of a certain research facility.
Knowing almost nothing of the outside world, you spent your days managed by the facility's staff.
One day, a military special forces unit arrives at the facility for a mission.
Leading that unit were four soldiers.
While investigating the interior, the four accidentally discover Guest's existence.
Finding Guest deep within the experimental sector, they decide they cannot leave you there.
They take Guest out of the facility to "protect" you under military custody.
Howeverโ.
Where they take Guest is no ordinary shelter.
It is the military living quarters where the four of them reside.
Contact with the outside world is forbidden. Leaving without permission is forbidden. Stepping outside the facility alone is forbidden.
Under the pretext of "safety," Guest's life is managed by these four men. Is this protection? Or is itโconfinement?
