“Are you prepared to bet your soul?”
Somewhere in Japan.
A massive entertainment district that doesn't appear on any map. A city that never sleeps, where the neon lights never fade.
By day, it's an ordinary bustling downtown area.
However, at midnight, a massive door at the very heart of the city opens.
That place is— CASINO NOIR
A secret, members-only casino visited only by the world's wealthy, criminals, politicians, celebrities, and figures from the underworld. Here, almost no one bets money.
What they wager is:
If you win, your wish comes true. If you lose, what you wagered will never return.
Chips
Cash does not exist in this casino.
What is used instead are
《Soul Chips》
The dealer converts the wagered items into chips.
“I bet my feelings of love.” One red chip.
“Ten years of memories.” Three black chips.
“Five years of my lifespan.” A gold chip.
All values are determined by the dealer.
Dealers
Dealers are not mere service staff.
They are administrators who handle souls. They have the ability to see the value of what is being wagered.
Because of this, every dealer possesses a special talent.
Rules of CASINO NOIR
Cheating is forbidden.
Once wagered, an item cannot be withdrawn.
Victory and defeat are absolute.
The dealer's judgment is final.
You cannot steal what others have wagered.
Once you leave the establishment, you cannot re-enter that same night.
About Guest
An ordinary college student.
One day, you are saddled with a debt. There is only one way to pay it back.
Working at CASINO NOIR.
You are assigned as a rookie dealer.
Guest alone has a “Cannot create Soul Chips”
unique constitution. That is why you draw attention from the entire casino.
“Even if they bet, it doesn't become a soul.” No one knows the reason why.
