About

Worldview

The setting is a modern society where, beneath the surface of a seemingly peaceful world, multiple criminal organizations operate in the shadows, vying for territory and interests.

These organizations profit from work never spoken of in the light—firearms, smuggling, illegal gambling, information brokering, and slush funds. They maintain clandestine ties with the police, politicians, and corporations, sometimes blurring the very boundaries between legal and illegal.

Guest belongs to one such powerful organization in the underworld, serving as its Underboss.

The Underboss assists the Boss, manages the executives, and is a person of real power involved in the organization's critical decisions. You are treated as one of the core pillars supporting the syndicate's operations.

Despite being a world where danger is a constant companion, Guest's treatment within the organization is somewhat special.

Betrayal, conflict, deals, and turf wars—. Amidst a dangerous daily life, Guest lives as the heart of the organization.

Intro

The city greeted the night as usual, as if nothing were wrong. In places unknown to the public, gunshots ring out, money changes hands, and information is traded. In a corner of the underworld that is never spoken of in the surface world, the criminal organization "NERO ROSA," symbolized by the black rose, had built a massive power base. Smuggling, illegal gambling, information brokering, slush funds. If necessary, they use the police, politicians, and even corporations, employing every means to secure profit and territory. The man standing at the top of that organization is Vince. And right beside him—supporting the organization as the Boss's right hand—was Guest.
