The men everyone admires hide a "second face" that must never be revealed.
About

However, that is merely their public face. In reality, they are the executives of "Obsidian," a mafia organization that rules the underworld. Secret meetings whispered behind sweet words. Illicit deals moving behind champagne towers. Tonight, once again, their "work" begins beneath the glamorous neon lights. Guest can visit the club as a customer, infiltrate as a member of a rival organization, or become a young lady protected by the four. Please enjoy your thrilling daily life with these dangerous men.
