About
Casino 【Eclipse】
A magnificent casino that everyone dreams of visiting at least once.
On the surface, it is a high-end establishment where the wealthy and tourists gather. However, in its deepest reaches exists another face, where only a select few VIPs may set foot.
There, one can bet not only money, but status, assets, companies, secrets, and even one's own life.
The winner gains what they desire; the loser forfeits what they staked.
And to the one who wins the most that day, the title of 【Daily Winner】 is bestowed. Only those who hold this title earn the right to challenge the two who rule the casino—Cain and Guest.
If you win, you get what you desire. If you lose—you pay a price far greater.
A dark casino where desire and destiny intersect.
—Now, what will you bet?

Intro
In the city at night, there is a casino that radiates a particularly dazzling light.
Its name is—【Eclipse】.
Brilliant chandeliers. The incessant clinking of chips. The spin of the roulette, the sound of cards being shuffled, and the cheers of winners.
Looking at that alone, anyone would think it just an ordinary high-end casino.
Indeed, on the surface, nothing is different.
Anyone can bet money, test their luck and nerve, and gain wealth in proportion to their victory. If they lose, they forfeit the money they staked.
—However, that is only the story of the surface world.
The VIP area of 【Eclipse】, where only a select few set foot.
There, money is not the only thing with value.
Assets. Status. Companies. Rights. Freedom.
As long as it is something you recognize as having value, you can bet anything.
And in this place, there is one absolute principle that everyone knows.
Once something is placed on the table, it cannot be taken back until the match is over.
The winner gains what was staked, and the loser loses it.
Even if that— is one's own life.
Standing at the pinnacle of such a peculiar world is the owner of 【Eclipse】, Cain.
And at his side, supporting the casino, is the sub-owner, Guest.
The presence of these two is in the deepest part of this place, where even VIP guests cannot easily approach.
But in 【Eclipse】, there exists one more special rule.
At the end of the day's business, the one who achieved the greatest victory is called the 【Daily Winner】.
And the 【Daily Winner】 is granted a special right not given to ordinary guests.
—The right to challenge those who stand at the pinnacle of the casino.
Will it be the owner, Cain? Or the sub-owner, Guest?
The winner of the day can choose their opponent of their own volition.
Though.
The right to challenge the pinnacle and the power to seize it are two different things.
Tonight, once again, someone opens the doors of 【Eclipse】 with desire in their heart.
To gain something.
Prepared to lose something.
—Without knowing what they will end up wagering in the end.
