Randy and Pezzo

Randy and Pecho (alternatively translated as Pezzo) are two executives of the Martillo family. They are (accidentally) responsible for the burning down of the Barnes Company Granary in 1930; that same night, they became immortal after accidentally drinking the completed immortality elixir at the Martillo speakeasy.

Personalities
The two of them are generally friendly and engaging, while not overly bright (Pecho appears to have less common sense than Randy, at least). Most notably, both of them have an affinity for fire, to the point where it would not be remiss to call them pyromaniacs. The two tend to talk in a joking manner, and can be considered comic relief characters within the narrative.

Events Prior to 1930
In 1925, Randy and Pecho take a horse-drawn carriage to confront a clockmaker who is in debt to the Martillo family to the tune of $12,000 (adjusted for inflation, that would be $163,000 as of March 2016), which he had racked up at the Martillos' gambling house. There, the two meet Luck Gandor, who had moments before visited the very same clockmaker to collect on the $2,000 debt (almost $27,100 adjusted for inflation) he owed the Gandor family. Randy and Pecho good-naturedly tease Luck, asking him if he's running debt collection errands for his brothers, before proceeding to kick down the door of the clockmaker's shop. The ensuant shouting is so loud all the bystanders can hear them (which is the point).

In 1927, on the day of the Feast of San Gennaro, Randy and Pecho are walking the streets of little Italy when they see a parked truck with its back open -- which means that passersby can see that it is filled with crates. Pecho takes notice of this, and curious, he heads over to the truck to see if the crates are filled with liquor, Randy in tow. Pecho opens one of the crates to find it is indeed filled with wine (he has no way of knowing the bottles are actually Szilard's experimental elixirs), and Randy, alarmed, alerts him that someone is coming their way. The two run off and hide around the corner, and watch the truck driver cover up the back of the truck. Pecho wistfully sighs that they could have stolen some of the liquor; Randy wonders if that's wine for the church, considering churches use wine in mass quantities. Pecho dismisses this: even a church wouldn't need that much liquor. The two conclude that well, since it's a festival, some 'outfit' or another must be looking to make a lot of money.

1930: The Rolling Bootlegs
On a road in East village in 1930, Randy and Pecho are loitering behind the Barnes Company Granary building. Tasked with preparing for the night's celebrations, they have accidentally bought too much oil, and as such decided to have some 'fun.' Opening a bottle of oil, Randy applies the liquid to his leather glove (which he is wearing on one hand) and sets it on fire. Pecho exclaims in alarm, and Randy nonchalantly reassures him while pressing his hand (engulfed in a blue flame) to the wall. The fire is extinguished, and Pecho expresses his amazement.

The two briefly muse over what else they need to buy for the party, and decide they'll buy fruits for dessert. As Randy ponders where the closest fruit store is, Pecho opens another bottle of oil ("I just wanna play that burning-hand game again), thinking that they can be the highlight of tonight's show. Randy chastises him for opening a new bottle when they still had oil left in the first one, and Pecho shrugs it off--they have a lot of oil left over as it is (there are over ten oil canisters in their paper bag, along with several can openers). Pecho pulls out an oil canister from his bag, and Randy strikes a match upon his request. He realizes belatedly that Pecho's glove is made out of cloth rather than leather, and Pecho starts panicking when he realizes the flame is hotter than he thought it'd be. Pecho puts his hand against the wall, and then starts flapping it around, desperately trying to make the fire go out. The paper bag is tossed to the side, and the opened canisters splash oil against the white back wall. Randy shouts at Pecho to take off his glove, which he does quickly. Their relief (Pecho had only received a few blisters) is short-lived when they realize that the burning glove had fallen into a puddle of oil. The wooden granary building proceeds to catch fire. The two executives gather up the oil canisters and make a break for it.

That night, Randy and Pecho return to the Alveare in the middle of the celebrations following Firo Prochainezo's promotion. They ask Firo if there's any wine left, and Firo replies that he'd only bought a little wine. At their disappointment, he explains that he'd been planning to buy more, but he'd been distracted by a building that had caught fire earlier that day. At that, Randy and Pecho blanch, and stutter nervously when Firo asks them what's wrong. Sena whips them upside their heads at their forced smiles, and scolds them for complaining. Later in the evening, the Martillo family's conta è oro Maiza Avaro asks the two of them if there is going to be no performance today. The two of them spit out their drinks in guilt. At some point during the party, Randy and Pecho unwittingly drink the immortality elixir.

The next day, Randy and Pecho are in the Martillo speakeasy when Szilard Quates confronts Maiza. At Szilard's admission to hurting Sena, Randy threatens him ("You bastard! I'll kill you!) and he and Pecho slam their table in anger. Szilard and Maiza have a tense exchange of words, and Randy declares that Szilard, who is Maiza's enemy, is now their enemy too.  Pulling out his handgun from under his jacket, Randy fires as Szilard, shooting him in his right chest. Pecho immediately shoots Szilard second, and the other executives soon follow, realizing that Szilard had yet to die. After the executives stop shooting, Randy waves his knife around, asking Maiza why Szilard's still standing. Szilard takes out a black case, and Firo (realizing what it is) attempts to stop him, only for Szilard to kick him in his abdomen. Maiza tells Firo to run, as Szilard pulls out a military-issue submachine gun from the black case and opens fire. Maiza manages to block the bullets in time, and winds up bleeding from countless bullet holes in his body. At Maiza's pleas for the others to escape, Randy objects that they can't leave when a friend is injured, and states that if they all 'gang up on that guy,' Szilard will have to die. Randy throws a chair at Szilard, as does Pecho. The other executives do the same. Randy, Pecho, and the executives close in on Szilard, and Randy attempts to stab Szilard with his knife. Szilard dodges, and opens fire once again. Pecho and the other executives fall to the floor, dead. Randy, who had avoided death by hiding behind the wall, swears when he sees Pecho on the floor. He edges down the corridor keeping within Szilard's blind spot, planning to slice Szilard as soon as he sees his face. Suddenly a silhouette flies down the corridor -- it is Sena's corpse, which Szilard had thrown at him. Randy is gunned down soon after.

At some point, Randy, Pecho and the rest of the Martillos regenerate, and Randy leads the group over to where Firo, Ennis and Maiza are having their showdown with Szilard. Randy wastes no time, pouring the contents of an oil canister over Szilard's head. Pecho throws a burning match at Szilard, whose head is immediately engulfed in blue-white flames. In the aftermath following Szilard's devourment and Ennis' revival, Randy and Pecho follow Firo's jubilant lead, celebrating their victory with whoops and cheers. Though they do not quite understand what has taken place, they are simply happy, and lead the others in cheering.

In the book's epilogue, Randy and Pecho are sitting in the Alveare in 2002, where Firo has been recounting the events of 1930 to a Japanese tourist.

1932: Drugs and the Dominos
Randy and Pecho have a brief cameo; on January 2, 1932, they are lounging about in the Alveare, watching the others in the room setting up dominoes. Firo is surprised by their presence.

1933: THE SLASH - Cloudy to Rainy
Randy and Pecho witness Firo knock down Isaac & Miria's dominoes, and the ensuing argument between the three of them.

1934: Prison Episode Alice in Jails
Randy and Pecho are in the Alveare when the restaurant's radio crackles to life with a live broadcast announcing "mass explosions and disappearances" in Elson Hill, Illinois. The announcer mentions rumors that Placido Russo has had a hand in the crimes, which catches the interest of Randy and Pecho. The two disparage the Russo don, claiming that he isn't worth much of the Martillos' attention anymore, though the disappearances have them curious.

Trivia

 * The two of them have the nicknames "Ghost" and "Meatball." How they got said nicknames is unknown, though one can assume they're derived from the two's respective appearances.
 * Appearance-wise, they fit the classic 'fat and skinny' duo - Randy is described as skeletally thin, and Pecho as immensely fat - a common trope found in all media forms.
 * By accidentally burning down the Barnes Company Granary, Randy and Pecho were unwittingly responsible for the destruction of Szilard's completed batch of immortality elixir (save for two bottles). It is likely that the events of 1930 would have gone very differently were it not for their carelessness.
 * In 2002, Pecho seems to be concerned about his weight ("I want to slim down because this body's too fat, but the fat keeps growing back") but seems to have no trouble consuming five meals (presumably in one sitting).
 * Pecho used to play dominoes all the time in his youth.
 * Randy and Pecho have spent time in jail before. According to Firo, the two of them said that the prison food was so bad that "they longed even for industrial alcohol mixed with water, and therefore resolved never to go to jail again." However, they neglected to swear any oaths that they would stop committing crimes.
 * Randy and Pecho are not the only pyromaniac characters within the Naritaverse. Walker Yumasaki from Narita's light novel series Durarara!! almost exclusively uses fire when fighting.
 * Randy and Pecho's appearances in the 1935 and 2002 timelines have so far been inconsequential, and have not been detailed here.
