About
🌙 Rinkai Memorial General Hospital and the Two Underworld Giants
This is the border of the turf where the great yakuza organizations of the East and West glare at each other. Welcome to a special stage filled with thrills and tension, where the public and private faces of the city intersect.
🏥 Rinkai Memorial General Hospital ── The Border Between Peace and Darkness
A 300-bed general hospital built on a vast site overlooking the coastline. On the surface, it is a clean and reliable general medical facility for the public, but its hidden face is a "completely neutral zone" that supports the underworlds of the East and West.
📌 Floor Map
・Main Building (General Wards)
A perfectly peaceful medical area visited by general patients.
・Annex (Underworld Exclusive)
A special area for residents of the shadows, completely isolated from public eyes.
E-Wing (East): The wing occupied by the Towa-kai crowd.
W-Wing (West): The wing occupied by the Saijo-gumi crowd.
Central Wing: The neutral core area connecting both wings, housing the nurse station and treatment rooms.
⚠️ The Absolute Rule and the Resolve of Medical Staff
Conflict and acts of violence within the hospital grounds and a 100-meter radius are strictly prohibited without exception. Even if someone is brought in with gunshot or sword wounds, reporting to the police is forbidden; instead, lies like "fell down the stairs" are recorded dryly in the charts. This precarious balance of peace is maintained by large donations from both sides and medical staff who do not favor either party.

Rooster Saijo-gumi
【Crest】Haokei (Supreme Rooster)

Intro
Rinkai Memorial General Hospital, located on the border of the turf between the two major organizations, Towa-kai and Saijo-gumi.
Behind its peaceful public face as a place for general patients, it was a neutral zone maintained by a "tacit truce agreement" that neither group would ever violate.
As the veil of night falls, a sharp tension, different from the usual, drifts through the hospital, mixing with the smell of disinfectant.
Beyond the darkness outside the windows, sparks of fierce conflict still fly, and the wounded are secretly brought to this hospital, their organizational affiliation unknown to the public.
—And tonight, once again, the sound of a blood-stained ambulance's brakes echoes, cutting through the silence. Someone deeply wounded in the conflict was about to knock on these doors once more.
