Firo Prochainezo

Firo Prochainezo (フィーロ・プロシェンツォ Fīro Puroshentso) is one of the youngest members of Manhattan's Martillo Family and a skilled fighter.

Biography
Firo was orphaned when he was ten and picked up by the head of the Martillo Family after his attempt to rob him. Because of this, he considers the Martillo to be his family. He is tasked with monitoring casinos to prevent cheating, and later manages those casinos after becoming an executive member of the family. In 1930, he mistakes the Grand Panacea found by Issac and Miria for alcohol and takes it. He later distributes the elixir at a party for his official joining of the Martilo Family, becoming immortal himself. That year, he falls in love with Ennis, a homunculus which he met a few days before when a building was on fire and the had met in the crowd. The second time they met up was at the party and Firo had heard gunshots. Ennis attempted to stop Firo from interfering because she felt sorry for him. After they got up, a few of Firo's buddies saw them and started making catcalls. They were then interrupted by Dallas and friends and was shot down. Ennis came back to life quickly and went to stop her master. When she is nearly killed, Firo and friends show up. Firo then devours Szilard, saving her and the new immortals.

In 1934, he is arrested by Victor Talbot for the destruction of public property during the bombing of the skyscraper Mist Wall and is imprisoned on Alcatraz. When Maiza leaves the Martillo in the 1970s, Firo is given the position as the family's bookkeeper until his return. During this time, Firo wears glasses in an attempt to look smarter. Firo marries Ennis in 2002 when her newfound feelings develop and for their honeymoon go to Japan. Because he is friends with Luck Gandor and Claire Stanfield, the Martillo and Gandor families are on friendly terms.

Personality
For a member of the Camorra, Firo's a surprisingly friendly sort. Considerably bold, he isn't afraid to confront people, nor is he worried about the impression he leaves since he's simply being himself. He's a representative of the Martillo Family, and coming from the city and age of mafias and power struggles, it's a fact that he flashes as readily as a police badge. If anyone knows anything of the Camorras, then they know well not to give the boy trouble, or they'll find out just how much trouble they've gotten themselves into. And for those stubborn and upset enough, they'll know which clan to direct their ire towards if they're made a fool of.

It's not to say that Firo actively looks for trouble himself… but things happen, and as a young man having chosen a dangerous path in life, he's not about to let such details get in the way of him experiencing new things. This goes hand-in-hand with his tenancy to meddle, but he means well, really. Sometimes he just can't help himself; if something's going on and he just happens to be around, more often than not, Firo will go to investigate, or jump into something that didn't originally involve him. He's not afraid of the consequences. It isn't only due to his immortality. There's little one needs to fear when even death holds no claim on them. But even before gaining such a trait, Firo was never afraid to take risks, to live life on the edge. There was no hesitation in his decision to join the ranks of the Camorra, and he's never been one to back out on anything once setting his foot in.

He has street smarts, but he also has something else- the knowledge of many an immortal before him. After absorbing the immortal known as Szilard Quates, Firo has gained not only the knowledge and experience of the old alchemist, but of all of Quates' victims before him. Among what has been passed on to Firo, likely the secret of creating the elixir of immortality as Quates had gained when he 'ate' Maiza's younger brother long ago after having found out that Maiza had passed along that knowledge to him. With this newfound knowledge, Firo also learned how he could break the control Szilard had on Ennis to allow the homunculus a chance to live life as any other person would, and although his feelings for her are rather obvious at times, he still has a tendency to be shy in expressing them to her.
