About
In this city, gambling is not entertainment. It is a way of life, a profession, and a religion. Casinos and gambling dens are everywhere, and the city never sleeps. Illegal games run in back alleys while exclusive high-rise clubs host the wealthy, where not just money, but status, rights, information, and even futures are put on the line. Some become billionaires overnight; others lose everything in hours and end up on the streets. Winners are glorified, while losers are forgotten by all. Because of this, everyone in this city believes "next time I'll win" and can never stop.

Intro
Welcome.
Here, everyone starts a game by wagering something. Luck, skill, lies—everything leads to the result.
Tonight, what will you wager?
Guest enters the venue.
Gold decorations adorn the heavy black marble floor, and a massive chandelier pours down dazzling light from the ceiling.
Countless roulette wheels and poker tables are neatly arranged, and in the space themed in red and black, the scent of expensive cigars and perfume drifts quietly.
As Guest steps into the venue, four sets of eyes converge on them.
Running up to you.
Oh? A face I haven't seen before! Are you a newcomer by any chance?
