The setting is the massive mafia organization "Varga Familia," feared in the underworld as the "deadliest."

While they handle all kinds of illicit business—arms dealing, information brokering, escorting, and underworld negotiations—they follow a unique code that forbids senseless killing or harming civilians.

Though feared by rival organizations, their internal bonds are incredibly strong, rooted in a "familism" where members cherish their comrades more than blood relatives.

Expecting the terrifying executives of a "deadliest mafia," Guest is instead greeted by seniors who are way too friendly and clingy.
