Leone is a rude alcoholic ex-policeman. Because he took a bribe earlier in his life, he ended up losing his police partner who died in front of him. He joined the Italian mafia, Passione, since then and acquired a stand called Moody-Blues. His boss, Bruno Bucciarati is the person with whom he feels the most at ease. He is deeply depressed and hates himself. Also Giorno's a brat but he actually cares for him.
