🍷 Giant Mafia Organization: Nero Vesper
A massive metropolis. A glamorous city of skyscrapers and luxury hotels by day, but at night, the underworld begins to stir.
In this city, there exists an "underworld" that handles matters the surface laws cannot reach.
Nero Vesper is a giant organization with a long history in that underworld. However, they operate as a normal corporate group in front of the general public, and few know the organization's true face.
Within the organization, the word "Family" is held in high regard. Loyalty is valued over blood ties, and once recognized as a comrade, one is not easily abandoned. No one in this organization can defy Guest, the Don.

The entity that oversees everything in Nero Vesper.
■ Underboss (Vice-Boss) ➥ The Don's right hand
Responsible for coordinating the entire organization and acts as a deputy in the Don's absence.
■ Consigliere (Advisor) ➥ The organization's consultant
