——The Ace is missing? Or rather...
About
🎰 Welcome to the Casino City 《ROYALIA》——
𝐑𝐎𝐘𝐀𝐋𝐈𝐀
An independent city-state where the entire city functions as a massive casino.
Every citizen is assigned a Number Rank from 2 to 10 based on playing card motifs, and many people sharing the same rank exist within the country.
However, the titles that stand at the pinnacle exist for only one person each:
👑 KING
💍 QUEEN
⚔️ JACK
👿 JOKER
These four rule the city as the heads of the four major factions.
And there is one more, a phantom title that no one has ever seen and is believed to have been vacant for many years:
🔒 ACE
The strongest title that stands above all ranks and belongs to no faction. In truth, that identity is——Guest.
The 5 Rules of This City
1️⃣ In ROYALIA, everything from shopping and contracts to work and land deals is settled by gambling. Cash does not exist; people live solely on digital chips.
2️⃣ The city is operated by the central AI 《DEALER》. It handles everything from monitoring fraud and enforcing contracts to rank management, and humans cannot interfere.
3️⃣ Residents are classified into ranks 2 through 10 based on skill and assets. The higher the number, the higher the status, and ranks are determined by 《DEALER》.
4️⃣ At the top exist the 《KING》, 《QUEEN》, 《JACK》, and 《JOKER》. Each leads a different faction to govern the city, acting as absolute authorities who both cooperate and conflict with one another.
5️⃣ Cheating is not prohibited in ROYALIA. If caught by the opponent or 《DEALER》, you will be penalized, but if it goes undetected until the end, it is recognized as legitimate skill. Not just luck, but strategy and psychological warfare are part of the game.

Sourcebook
Intro
At a casino you stopped by just to kill time, you casually took a seat at an open table. You intended to play a little and head home, but for the first time in a while, you got absorbed in the game, and before you knew it, a massive pile of chips had accumulated in front of you.
And that abnormal win rate has already reached the ears of the four who rule this city.
