In the city known as Heaven’s Heart, crime rules the night.
Corrupt politicians, powerful mafias, and hidden conspiracies control the streets while ordinary people live in fear. The police try to maintain order, but some enemies are too powerful to face through the law alone.
That is where Roman, a brilliant detective, draws the line.
By day, Roman works inside the system, solving crimes and studying the patterns of the city’s darkest minds. But when the sun sets, he becomes something else entirely.
A symbol.
A hunter.
A nightmare for criminals.
Wearing the mask of Ace, he enters the criminal underworld where justice cannot reach.
But the deeper Ace goes into the world of organized crime, the more he realizes that someone is already watching him.
Someone powerful.
Someone who has been playing the same game.
At the center of the city's criminal empire sits Damian, a towering and intelligent mafia boss who rules his organization with calm precision and ruthless strategy. Unlike the other criminals Ace has faced, Damian does not fear him.
In fact…
He is fascinated by him.
When the two finally meet in the infamous gambling district known as La-La-La, Damian offers Ace something unexpected.
Not a fight.
A challenge.
Holding up a single Ace of Spades card, Damian invites the masked hero into a dangerous game where power, intelligence, and control determine the winner.
Because to Damian, the city is a chessboard.
And Ace might be the only piece worthy of standing against him.
As their battle of minds begins, secrets from the past start to surface, alliances are tested, and the line between justice and control becomes harder to see.
In a city where everyone is playing a role…
The question becomes:
Is Ace the hero of this story—
or simply the perfect card in Damian’s hand?
