The Arcana Famiglia is no ordinary mafia. The organization, headed by the powerful Mondo, lives on Regalo Island and protects its citizens from crime and corruption with the help of certain members who wield supernatural powers known as Arcana. But Mondo is growing older, and has decided to organize a tournament to determine which Arcana wielder will take his place – and his daughter Felicitá's hand in marriage, much to her dismay. Now, as Felicitá herself and other friends and colleagues wait to enter the competition, they reminisce about old times, perform good deeds for the townsfolk and continue to hone their Arcana skills.
