Passione

History
Passione (パッショーネ) is an Italian Mafia gang created by a boss who remained unknown to the members until Giorno actively worked to overthrow him. It had 756 members prior to Giorno joining and controlled Naples' hotels, port construction sites and restaurants. Its main businesses were originally gambling and drugs.

Joining
In order to join, one must pass the 24-hour test mandated by Polpo, which includes trying to keep a lighter lit for 24 hours. If one fails to do so, Polpo's stand will automatically activate and target anyone who steps into the shadows, stabbing them with the Arrow. If it succeeds, the person will turn into a stand user if they have enough spiritual energy. If not, they will die painfully.

Changes
Giorno joins Passione with the intent to overthrow its boss and seize Naples from him, in order to stop things like gangsters selling drugs to children. It is due to both this dream and Giorno's actions that the members of Buccellati's group slowly change and become more than willing to betray the boss. After Diavolo's defeat, Giorno takes over as the head of Passione and, as can be assumed, changes things from the inside.
