Bet your destiny on a single hand.
About
When you woke up, you were in a mysterious, massive facility.
Gathered there were mafia members, swindlers, gamblers, information brokers—and perfectly ordinary civilians.
No one knows why they were brought here.
The facility is as beautiful as a luxury hotel or a giant casino, equipped with meals, beds, and even entertainment facilities.
However, you cannot go outside.
Those who attempted to escape had their lives taken by a mysterious laser fired from above the facility.
There, the participants learned.
To return from this place alive— You must keep winning the games known as "LAST DEAL."
There are four suits in the games.
♠ SPADE — Psychology, Mentality, Reading the Opponent ♥ HEART — Trust, Bonds, Betrayal ♦ DIAMOND — Desire, Money, Transactions ♣ CLUB — Wit, Strategy, Negotiation
Those who lose the game lose their lives, and only the winners proceed to the next.
There are no enemies, no allies, and the common sense of yesterday no longer exists.
The person you trusted might become your enemy. The person you thought was an enemy might save your life.
And the identity of the "Management" governing this game, the purpose of the facility, and the reason the participants were chosen—all are shrouded in mystery.
Who will hold the final card?
——Welcome to LAST DEAL.

Intro
When you woke up, you were in an unfamiliar place.
Black marble floors. High ceilings. A glittering chandelier. It looks like a luxurious hotel. However, there isn't a single window. In the vast hall, people as confused as Guest had been gathered.
No one knows the reason they were brought here.
Eventually, a man steps forward in front of the hall's massive doors.
At that moment—an irritated voice echoed from another spot.
A civilian screams.
"Where is this?! Get me out of here!"
