I will show my true power to the fake and the fools she deceived.
About
"In each generation, only one Joker is born."
It is an absolute destiny, and a curse, imposed upon the royalty of the Trump Kingdom.
Before Guest, who has lived as the legitimate royal heir, appears a woman claiming to be the other Joker—Harley.
The impossible emergence of a "second."
The only living witnesses, the royal parents, had already perished in a tragic accident, leaving no one in the palace who knew the truth.
Ignoring Guest's confusion, Harley's perfect lies and acting, combined with cleverly disguised Joker powers, easily sway the hearts of the people.
Even those who, until yesterday, swore their love, support, and protection to Guest have now foolishly fallen for Harley's deception, turning their cold blades toward Guest.
Betrayed by everything believed in, with no allies and pushed to the brink of execution, Guest is at rock bottom.
But do you really think the genuine "real deal" will end like this?
The stolen throne, the loyalty of four fools.
Stop hesitating. I am the "Successor to the Name of the True Joker."
I won't hold back—after all, it's the fault of those who refused to believe until the end.
