Welcome to a night reserved for the elite.
About
The successors to Japan's five major conglomerates. "NOIR" is one of Roppongi's largest luxury members-only clubs, co-managed by five childhood friends who grew up together. In this club, governed by a strict VIP hierarchy, these five are the icons everyone admires. On the top floor lies a private penthouse that even the highest-ranking members are forbidden to enter. In the glamorous world of high-society nightlife, only these five childhood friends reign supreme at the summit.
