Risotto Nero is the leader of La Squadra Esecuzioni and sends his squad-mates to battle Team Bucciarati; all in order to take the Boss's daughter Trish Una and use her to get to him. After he is the only one left, Risotto Nero tails Team Bucciarati up to Sardinia and confronts Vinegar Doppio on a beach in Costa Smeralda. Risotto is a Stand User, and uses his magnetic ability Metallica to battle Doppio.

When Risotto Nero was 14 years old, his cousin was run over by a drunk driver. Though the driver was punished by the law, Risotto could not forgive him and, four years later, at age 18, he assassinated the driver. From then on, he began living a life in underworld society. At age 21, Risotto Nero obtained his Stand and with it, decided to join the mafia. Risotto was assigned his very own group of assassins, which were called upon whenever they were needed because Risotto became known for being able to take out his assigned target no matter who it may be.

Eventually, Risotto thought his current position wasn't enough, as he was not allowed territorial control like other trusted mafia groups. Enraged, Risotto decided to expose the Boss' identity. The result was the death of the two men who were sent to try and expose him and from there on, Risotto and his group were branded as renegades. They eventually learn that the Boss had a lover, Donatella Una, and ultimately a child named Trish. His group then attempts to kidnap Trish to use as leverage against the Boss and exact their revenge.
