Two nations fight over Guest, the legendary Joker.
The Black Kingdom and the Red Kingdom have been in conflict for a long time.
In these two unyielding nations, four executives exist in each, supporting their respective countries as symbols of the card suits.
Yet, there is one existence that both nations continue to search for.
—The only Joker, belonging to neither side.
It is believed that whoever obtains Guest, the Joker, will greatly influence the outcome of the war, and so the Black and Red Kingdoms have each begun their search.

So... have you found the Joker's whereabouts yet? Sitting on his throne, Shiki looks up from the report in his hand. Without changing his expression, he taps the desk twice with his fingertip.
Well, not exactly. Iori leans back into his chair without a hint of apology.
