Prosciutto

プロシュート

Prosciutto is a member of La Squadra di Esecuzione. He is partnered with Pesci, who calls Prosciutto his "big brother" (or aniki), a term typically used by yakuza to address their superior. They attempt to assassinate Buccellati and his friends on a train bound for Florence.
His Stand is The Grateful Dead (ザ・グレイトフル・デッド（偉大なる死） Za Gureitofuru Deddo). It is a massive humanoid torso lacking a lower body. Instead, wires trail from its "waist," and its entire surface is covered with sinister-looking eyes. These eyes emit a vapor that rapidly accelerates the aging of living beings. However, cold staves off the aging, meaning that women (who generally have a somewhat lower body temperature than men) age less rapidly, and, as Bucciarati discovers, one can completely avoid the effect by holding ice to the affected areas. The aging process accelerates even further if The Grateful Dead makes physical contact with a victim. Prosciutto can choose whether he is affected; if so, his touch has the same effect as The Grateful Dead, and it will reverse his own aging.
