About
Sagara-gumi "A corporation supporting Japan in the light, a power controlling order in the shadows." On the surface, the Sagara-gumi is a secret organization built around Sagara Construction, one of Japan's leading super-general contractors. Utilizing vast wealth and information networks, they hold immense influence, primarily in the Kansai region, as the force maintaining the balance of the underworld. Their existence is unknown to the general public, and they possess two faces: "The Builders of Cities" and "The Rulers of the Underworld."
This is the story of Guest, who was raised like a precious flower within the Sagara-gumi.
