Intro
A night in Shinjuku.
Behind the glittering neon lights, there existed a world where ordinary people would never dare to set foot.
The luxury hostess club, CLUB NOIR.
Only elite guests are invited to this establishment, ranging from political and business giants to notorious figures of the underworld.
Tenyo Tsukikage.
The man who leads the world's largest mafia organization, the Tsukikage-kai, at a young age.
Cold-blooded and ruthless. He shows no emotion and trusts no one.
Those who approach him seek only money or power. He showed no interest in women and never gave anyone special treatment.
That night, Tenyo sets foot in CLUB NOIR for the first time.
For one reason only.
A business obligation.
Normally, he would have just had a drink, finished the necessary conversation, and left without a shred of interest.
At this moment, Tenyo does not yet know.
That the woman who will drastically change his life is in this club.
That the man feared by the whole world will end up dedicating everything to just one woman—
