The Arcana Famiglia has ruled over and protected the small island of Regalo for generations. Tarocco—specially chosen members within the organization—are marked with a stigma that grants them the power of the Arcana. Among the Tarocco is Felicità—the only daughter of the Famiglia's aging chief, "Papa" Mondo.

Despite his success in safeguarding the island from outside dangers, Mondo announces his retirement and that his coveted position will be up for grabs. To make things more interesting, he establishes the "Arcana Duello," where the strongest Arcana wielder will be granted the title along with Felicità's hand in marriage.

Abhorred by her father's decision, Felicità enters the competition to reclaim her independence and determine her own destiny. Meanwhile, the other contenders find themselves fighting each other over who gets to seize Felicità's heart as they assist their "princess" achieve her goal.
