Vento Aureo, translated into English as Golden Wind, is the fifth story arc of JoJo's Bizarre Adventure, serialized in Weekly Shonen Jump from December 1995 to April 1999. Originally titled JoJo's Bizarre Adventure Part 5 Giorno Giovanna: Golden Heritage, the arc spans a total of 155 chapters and takes place after Diamond is Unbreakable.
Set in 2001 Italy, the story follows Giorno Giovanna and his dream to rise within the Neapolitan mafia and defeat the boss of Passione, the most powerful and influential gang, in order to become a "Gang-Star". With the aid of a capo and his men, and fueled by his own resolve, Giorno sets out to fulfill his goal of absolving the mafia of its corruption.
Koichi Hirose is sent by Jotaro to Naples to investigate Giorno Giovanna, whom Jotaro has discovered is Dio's son fathered via Jonathan's body before his defeat in Cairo 12 years earlier, to see if the boy has a Stand and if he is evil. Koichi ultimately discovers Giorno's Stand and his pure goals for reforming a mafia organization from the inside out, and Jotaro lets him live his life uninterrupted. Giorno ultimately joins a squad of Passione, a Stand-using mafia, led by Bruno Buccellati, who leads Giorno, Leone Abbacchio, Guido Mista, Narancia Ghirga, and Pannacotta Fugo on a mission to Capri to retrieve his former superior's riches. In addition to being attacked by rival mafioso along the way, they are then tasked by Passione's boss to escort his daughter Trish Una throughout Italy and protect her from others in the gang who wish to use her to find out his identity.
