Get to the Collessium in Rome! (Episode)

Destination: Rome! The Colosseum (目的地はローマ！コロッセオ) is the twenty-ninth episode of Golden Wind and the one hundred forty second episode of the JoJo's Bizarre Adventure anime. The episode covers from Chapter 551 to the first half of Chapter 554 of the original manga.

Summary
Having made a mould of the Boss' face and fingerprints from the negatives, Team Bucciarati leaves the beach while Giorno researches the fingerprints. Although Trish realizes that the Boss was nearby, Bucciarati is against seeking him at the moment; new enemies must be gathering and they still aren't certain of the Boss' identity. However, the team's efforts to investigate all possible databases of fingerprints, from criminal records to death records, come empty.

Suddenly, someone directly calls the team through the laptop, declaring that they're allies both trying to defeat the Boss of Passione: Diavolo. The caller proves that they are actually working against Diavolo then invites Team Bucciarati to meet in Rome, showing a picture of the Arrow and claiming that there is another hidden potential that can be acquired, the likes of which could defeat King Crimson. Suspicious, Bucciarati still accepts the deal and the team leaves Sardegna on boat. However, Diavolo has been observing the team from afar and correctly guesses that the team is up to something. He orders Doppio to pursue the rogue Passione members and to call in his organization's most dangerous and depraved Stand Users: Cioccolata and Secco.

Meanwhile, Team Bucciarati's mysterious ally explains the origin of the Arrows; the items are made from a meteorite that crashed in Greenland, which was rediscovered in 1987 by a team of surveyors. Incidentally, the surveyors all fell ill and died but one developed extrasensorial powers. In truth, a virus contained in the meteorite is infecting people and somehow makes those who survive it Stand Users. Long ago, the Arrows were created from the meteorite and Stands began to proliferate in the world. However, the caller then refrains from revealing the hidden potential of the Arrows. When Bucciarati asks where they should meet precisely, the caller tells them to go to the Colosseum in Rome.

Night has fallen as Team Bucciarati arrives at a small coastal village near Rome; Mista and Narancia go on the lookout while everyone else remains inside Coco Jumbo. Soon, the drunkards on the seaside promenade are affected by a strange substance eating at their body. Seeing the grey goo eating at all the people nearby, Mista understands that they are under attack. However, when he draws his gun, he realizes his hand has been somehow infected. Unbeknownst to the Team, Cioccolata and Secco are filming them from a vantage point. Cioccolata has just deployed his Stand, Green Day, which spreads mold in the air.

A flashback reveals that Cioccolata, age 34, is a murderous former surgeon. Cioccolata has a history of torturing the residents of a retirement home when he was young and murdering his patients when he was a surgeon, all to observe the death and suffering of others. Cioccolata somehow acquired an assistant and human pet in Secco, one of his patients. The two currently form an exceptionally deadly team within Passione. In the present, Doppio has boarded a plane toward Rome, being instructed to rein in the two psychopaths before they cause too much damage.

Meanwhile, Team Bucciarati notices that the whole village is being devoured by a strange mold. Unable to detect the enemy, Narancia decides to retreat; the moment he jumps into the boat, his entire body becomes infected by the mold, alongside Giorno and Trish. Despite their condition, Giorno guesses that the Stand attack is triggered by downward movement, being inspired by existing types of mold that specifically prefer low altitudes to spread from there. With his whole body decomposing rapidly, Narancia tries to throw Coco Jumbo back to Mista; unfortunately, his hand falls apart mid-throw. Thinking quickly, Mista shoots the boat's engine to make it explode, sending Narancia and the turtle up to the shores and saving the team. Bruno gets out to replace the wounded Narancia, sending him to the turtle to be treated by Giorno. Deciding that the priority is to reach Rome, Bucciarati and Mista choose to ascend some stairs to reach a parking lot.

Seeing the team having survived their ordeal, Cioccolata is somewhat impressed.

Manga/Anime Differences

 * The stranger that contacts Bucciarati's group has an added line stating that the Stand Arrow doesn't just unlock Stand abilities in people, foreshadowing its true nature.
 * The scene presenting the Arrow and the origin of the Stands is more elaborate.
 * However, the brief exchange between the stranger and Bucciarati regarding where the stranger got the arrow has been removed, most likely to make the true identity of the stranger less obvious to new viewers of the series.
 * The scene where Diavolo presents Cioccolata and Secco to Doppio The scene where Diavolo presents Cioccolata and Secco to Doppio is moved to just after the duo's first true appearance, and has also been altered. The scene is narrated by the anime's narrator instead of Diavolo, only the flashback is featured, and Cioccolata's exactions are directly shown.
 * Due to the change in narrators during this scene, Diavolo's comment about his original desire to have Cioccolata and Secco killed is removed.
 * The scene of the drunkards succumbing to the effects of Green Day is slightly shortened, with the green-shirted drunkard immediately jumping off the staircase (whereas in the manga he panics for much longer before jumping). Furthermore, the short scene of the drunkard attempting to run away after his legs snap off is removed entirely.
 * Cioccolata and Secco's first true appearance is moved to immediately after Mista's hand is infected.
 * This exchange is also slightly extended, with Secco confirming that the camera is rolling and Cioccolata expressing satisfaction towards Secco's confirmation.
 * The scene of Narancia scanning the city and seeing the various corpses of infected civilians is moved slightly further. The civilians are also shown in much less detail, appearing to be already dead instead of being merely on the verge of death.
 * Green Day's first appearance is moved to when Cioccolata realizes that the group has figured out its ability.
 * After Mista shoots the boat and the gang is sent onto solid ground, Cioccolata expresses interest in this development instead of frustration.
