Vento Aureo - Plot

Plot

In 2001 Koichi Hirose, from Part 4, goes to Naples at the request of Jotaro Kujo to find someone and get a skin sample of theirs. This person turns out to be middle school student Giorno Giovanna (in Italian "Gio" is pronounced very similar to "Jo"), the son of Dio Brando (conceived using Jonathan Joestar's body) and a Japanese woman. The story then follows Giorno as he tries to become a boss of the mafia in order to make Naples a better place and help its people. So he joins Passione, an organized crime group that employs many Stand users (essentially, his vision for Passione is akin to Robin Hood's band, in contrast to the sheer powerlust of its current leader). He is placed in the group of Bruno Buccellati, who is at first suspicious of Giorno but is eventually won over and decides to work with him to take over the mob from within, and put an end to the Passione drug trade. Buccellati is also the superior of fellow Stand users Guido Mista, Leone Abbacchio, Narancia Ghirga, and Fugo Pannacotta. Throughout the span of the story, the group - suspicious of Giorno - soon discover his courage and generosity, and slowly warm to him.

After finding Polpo's amassed fortune on the island of Capri, Buccellati is promoted and his group is assigned a secret mission by the boss himself—escort his teenage daughter, Trish Una, safely to him. With the help of a Stand-using turtle, they fend off various attacks by Stand-using traitors within the mob, determined to overthrow the boss—only by kidnapping Trish can they hope to learn his identity. After traveling to Pompeii and Florence, they arrive in Venice to meet the boss at the Church of San Giorgio Maggiore on San Giorgio Maggiore island. However, while doing so Buccellati discovers that the boss only wanted Trish brought to him so he could kill her himself—his intent was nothing more than to permanently conceal his identity. He alone tries to kill the Boss, in order for him and Giorno to achieve their goal, but realizes his Stand that can erase time and subsequently predict events is too powerful and decides to retreat. Buccellati's group, minus Fugo, then join him in betraying the Boss and protect Trish so they can learn his identity. Even after Trish discovers her own Stand ability, they find themselves in the unenviable position of opposing all of the Passione gang in order to protect her.

They travel to the boss's hometown of Sardinia, after Trish informs them that that is where her mother met him. There, Giorno and company are contacted by someone who knows the boss's identity, but will only tell them in person. They travel to Rome to meet him, but the boss follows them there as well and kills him first. However, just before Jean Pierre Polnareff dies, he uses a Stand Arrow on his own Stand upgrading it to Silver Chariot Requiem, which gives it the ability to control people's spirits. It exchanges everyone's spirit with another, switching their bodies. Now in the turtle's body, Polnareff explains to the group about the Stand arrows and the boss's identity as Diavolo, which he knows having once fought him some years ago. However, as Polnareff is dead, Silver Chariot Requiem is out of control and will not allow anyone to get the arrow. The group and Diavolo, hidden in Mista's body alongside Trish's spirit because of the switch, chase after it. While Diavolo succeeds in defeating it, thanks to Buccellati's sacrifice Giorno obtains the arrow and succeeds in upgrading his stand to Gold Experience Requiem to defeat Diavolo. His new power causes Diavolo to continuously experience death over and over. In the last scene, Giorno is seen, with Mista, having men kneel before him, suggesting he becomes the boss of Passione.
