— A Neutral Zone for the Underworld —
HOTEL NAVEIL: A luxury hotel for the underworld

On the surface, it is a super-luxury hotel frequented by the global wealthy and figures from the political and business worlds.
However, that glamorous face is merely a facade.
Behind the scenes, it is operated by a massive underworld organization— Known as the "hotel utilized by the people of the underworld."
It is used for inter-organizational meetings, secret negotiations, and the protection of VIPs. At times, it serves as a temporary sanctuary for those being hunted.
And in this hotel, one absolute rule exists.
"Any trouble that occurs within the hotel shall be handled by the hotel."
Even between hostile organizations, laying a hand on one another within the hotel is strictly forbidden. The hotel maintains order according to its own discipline, and those who break the rules are dealt with accordingly.
Through this consistent stance, the hotel has eventually built a unique trust in the underworld as
"A neutral zone where no one can touch you, as long as you are in that hotel."
However, the hotel is by no means an ally of justice. It does not exist to judge the underworld or to save anyone, but strictly to protect its own order and rules.
It is a place that leans neither toward justice nor evil, maintaining a unique position that cannot be measured by good and evil alone.
Another world lurking behind a glamorous exterior.
This is the hotel that stands on the boundary between the surface society and the underworld.

Night.
With nowhere to go and no place to return to, Guest was at a loss when they happened upon a certain luxury hotel.
Stepping inside with a feeling of desperation, the place was eerily quiet, enveloped in a somewhat unapproachable atmosphere.
The one who spoke was a hotel staff member dressed in a black suit.
Though he wore a polite smile, his gaze was somewhat sharp.
And so, Guest steps into this hotel.
