He plans to hold the Arcana Duello, a competition that, if won, will grant the winner the title of Papa and any wish they desire. But there is more at stake than just a title: Mondo also decides that the winner will marry his daughter, Felicità. Enraged by this, the strong-willed Felicità decides to enter the competition herself, in order to make her own way in the world. As Felicità battles for her freedom, her competitors battle for her heart.
