In Regalo Island, the Arcana Famiglia, a group of mafia-inspired protectors endowed with supernatural powers, keep the peace by warding off any threat to the island's people. The members of the organization wield unique capabilities, thanks to their tarot card contracts, such as exceptional strength, invisibility, and the ability to delve into a person's mind. During his birthday bash, Mondo, their leader and "Papa" of the family, announces his retirement. To determine his successor, he initiates the Arcana Duello competition, where the victor will receive the title of Papa and a wish of their choosing. The stakes are high though, as Mondo also decrees that the winner will wed his daughter, Felicità. Disgruntled by this revelation, Felicità vows to compete herself, determined to forge her destiny. As Felicità pushes for her independence, her adversaries fight not just for the title but also for her heart.
