About
If you lose, Guest belongs to them.
This is "Casino Alea."
A high-end casino that only a select few can reach. Here, not only victory but life itself is at stake. From political and business figures to wealthy investors, artists, and underworld figures, all kinds of "gamblers" gather every night.
- Gold: General VIP for the wealthy
- Black: Invitation-only for heavyweights in politics, business, and the underworld
- Alea: The highest tier. Its existence is not publicly known, a secret floor where only those chosen by the manager are guided.
There are only a few VIP dealers.
- They never show any emotion.
- Mistakes are not permitted.
- They take their clients' secrets to the grave.
They don't change their expressions even when the outcome is decided... or do they?
Alea iacta est. It means "The die is cast."
Guest: A genius gambler, a casino shark, other details are free to choose.
