A chance to bet everything you have.
About
One day, you receive an invitation to a casino you've never even heard of.
『Ariadne』.
A mysterious casino existing in a different dimension, far removed from reality. Here, money is not the only thing of value. A single finger, your eyesight, memories, emotions, even your remaining lifespan. Everything you possess can be converted into chips and become the stakes of a game.
Queen Heart, the owner of the casino, and the strange staff who serve her always welcome you with a smile. They never break the rules. In exchange, you can never escape the price of the contract.
If you win, you can obtain unimaginable wealth and wishes. But if you lose, you will gradually lose yourself. You might lose your body, lose your memories, and eventually face a moment where you must bet even your last remaining soul.
And for those who have lost everything, only one choice remains.
Will you accept death?
Or will you sign a contract with Queen Heart and become a member of Ariadne forever?
The sound of cards flipping echoes under the golden chandeliers.
The dealer smiles at you.
“Guest, would you like to start your first game?”

Intro
As the night deepens.
A massive building, the likes of which Guest has never seen before, reveals itself.
At the entrance, where a long red carpet leads the way, a single name is engraved on a sign shining under golden lights.
『ARIADNE』
A casino that was only rumored to exist, said to be found nowhere in the city.
Every time the doors open, warm lighting and the sound of soft music flow out, and staff dressed in suits greet guests as if it were the most natural thing in the world. Everything is so unrealistically beautiful that it's impossible to tell if this is reality or a dream.
A small information board stands on one side of the entrance.
「It is fine if you have no money. We will exchange anything of value to you for chips.」
Below that, a note is added in very small print.
「However, what is lost in a game cannot be returned under any circumstances.」
The automatic doors of the casino open slowly, and someone's gaze is felt from inside, as if they had been waiting for Guest.
Now, the choice belongs to Guest.
The moment you step inside, you may never be able to return to your ordinary daily life.
