Ronny Schiatto

Ronnie Schiatto is the demon that was summoned aboard the Advenna Avis by Maiza Avaro to grant the crew of alchemists immortality. He gives the entire crew the elixir of immortality, the Grand Panacea, and only tells Maiza how to make it just in case someone wanted to make more of it; however later he implies to Huey Laforet that he was "expecting something to happen".

Ronnie becomes human by request of Elmer, who wishes for Maiza to have someone to stand by him after he had lost his younger brother, Gretto. Ronnie, however, denies that he stayed by Maiza's side because of Elmer's wish and claims he stayed because of his own curiosity. He currently works as the Martillo Family's secretary. He is the driving force behind the entire storyline and one of the supporting protagonists in 1933 - The Slash.

Personality
Like Huey Laforet, Ronnie is a bit hard to read and understand. Though not really adamant about people not knowing who he is or his past he is not the type to bring it up himself unless he is asked, which he hardly is. He is both refined yet also mysterious and cryptic, unafraid to use or have people know about his otherworldly powers yet seems more content to leave their origins to those that he meet's imaginations.

Durings the 1700s he showed himself shrewd and direct in his approach yet also rather extreme in his methods to prove his sincerety in cutting off Szilard Quates's head just to prove the existance of the Grand Panacea.

In the Prohibition Era he acts like a mentor to Firo Prochanezo while still maintaining his trademarked, daresay gentlemanly-with-a-mysterious-vibe outwardness, while being a warm and amiable person to approach. He is loyal to the Martillo Family and treats its members with great respect, and is also kind and polite to the Gandors as well.

None the less he is also rather curious and intrigued to what will happen if he does or does not interfere in certain events such as allowing the Martillo Family and the Gandors to drink the Grand Panacea.

Powers and Abilities
As a demon, Ronnie can appear where ever he wants and he can be summoned “simply by thinking about him”. He also declares that he can hear people’s words especially the ones in people’s heads which suggests that he has a form of telepathy, this is again evident when he puts “mental restrains” of those who drink the wine of immortality (restraints that also work even if the person is unnaware that he or she is conversing with another immortal as seen with Czeslaw Meyer to Isaac and Miria) and can implant knowledge into people’s minds like what he did to Maiza when he bestowed the information how to create the wine. He has no need to talk because he puts his voice straight in to people’s minds.

Ronnie has the ability to make something out of nothing as seen of the Advenna Avis when he manifests the wine of immortality into Maiza’s hands. It is unkown if he created it from throught or if it was some form of teleportation however as he could also materialize Adele's spear in his hands in an instant and teleport Isaac's "Ransom" letter to the Martillo's Speakeasy the Avaera without leaving Isaac or Miria's side.

When he walked into the Genoard Mannor he could attract the attention of all and make everyone's internal clock stop suggesting he can possess unnatural aura due to his demonic state.

He also seems to have no physical body as a demon, but can interact with the physical world if he wants like when he cut Szilard’s head in half to prove that the wine would make you immortal if you choose to drink it.(he can also take any physical shape and from).

Ronnie is said to be the equal to the Rail Tracer (aka the Legendary Assassin Vino) that is acknowledged even amongst those who have faced both, such as Jacuzzi's gang.

He has implied that he has some of the benefits of immortality without some of the restrictions as he is able to use false identities and lie about his name (he has stated that Ronnie Schiatto is a name he gave himself) and cannot die, though he has not yet been seen injured. He has stated that he can devour, though he has yet to do so.

When speaking to Elmer he stated that he can take away immortality, rerwite its rules to a certain indivdual and give a host of other abilities such as mind control as well.

Ronnie can identify the Grand Panacea by simply looking at it.

1930 - The Rolling Bootlegs
Although not yet identified, the Demon who would become Ronnie was summoned after 103 years much to his chagrin to provide the secrets of immortality to a group of alchemist onboard the Advenna Avis in 1711. He does so without protest and after providing instructions on the immortality elixir or Grand Pancea he witnesses the tragedies that led to the main story of The Rolling Bootlegs. He tells the ingredients and methods of making the elixir to Maiza Avaro.

In 2002, the demon, now named Ronnie was called to apprehend Bobby Splot's gang to reclaim a piece of camera belonging to the unnamed japanese tourist acquainted with Firo while Firo (dressed as Maiza) talks with the Japanese man about his past and how he was involved in the spiraling story of the immortality elixir.

Ronnie was present at the time of when the Martillo, Gandor families, Isaac Dian and Miria Harvent consumed the Grand Pancea before Szilard's assault against the Martillos after failed attempts to hire thugs (Dallas Genoard and his cronies) and Ennis failed to procure results. He did notice the drink, but chose to not intervene. He concludes this new group of immortals will be able to muddle through eternity.

In 2002 he returns the camera stolen from Bobby with no effort. When asked, Ronnie assumes his true form, which causes the tourist to faint, the tourist couldn't described Ronnie at all but chose not to pursue it further.

1932 - Drugs and Dominos
Ronnie describes the Daily Days, stating their omniscience and ability to acquire new information almost every second of the day.

2001 - Children of Bottle
Ronnie appears in a flashback during the time when he was the nameless demon. Ronnie and Elmer discuss their terms of agreement in the bottom of the ocean after Elmer fails to apprehend Szilard Quates. Elmer requests Ronnie to accompany Maiza from then on, and requests to see Ronnie smile. Ronnie does so, pleasing Elmer.

1933 - The Slash
Ronnie is called in by Maiza on behalf of the Martillo family to settled a dispute with Jacuzzi Splot and his gang for doing business in New York at their very turf in the eve of Prohibition ending. In the same time, Isaac and Miria are angry at Firo for ruining their Domino stacks and leave the Martillos to meet with Jacuzzi. Ennis also joins them to check on the duo, with Ronnie saying he will try to coerce the duo to return. When they left, Firo wonders how Ronnie is able to negotiate with a numerous amount of people alone and still be able to get beneficial results for the Martillos. Firo later deduces to Maiza that Ronnie could not be human, a same sentiment that Ennis notes on their walks due to Ronnie's commanding presence, stating she could sense some similarity to him but vastly more powerful.

Ronnie and Ennis arrive later after Tim and Adele were demonstrating the power of Immortality to Jacuzzi via Dallas Genoard. Ronnie demands an audience with Jacuzzi to speak to them about their business interfering with their turf. However, Chane Laforet and Maria Barcelito of the Gandors cause trouble in the mansion resulting in Adele stepping into the fray. Ronnie, impatient about these escalating issues uses his reality warping powers to hold onto Maria and Adele's weapons and use his deathly aura to stop anymore violence. This results in Nice using a smoke bomb to escape from Ronnie, Ennis, Adele, Tim, Tick and Maria due to the situation almost treading in dangerous grounds and the fact that the mansion belongs to Eve Genoard.

He teleports a 'Ransom letter' made by Isaac at the latter's request to the Alveare, which causes Firo to panic and find the missing duo.

That evening in one of the Martillo's family business establishments, Ronnie, Ennis, Isaac, and Miria are pondering how will they be able to get to Jacuzzi to discuss their dispute while Ronnie has a premonition that things will take its toll for the worse. He notes Ennis' distress on Adele's words due to her apparent association to Szilard Quates and tells the young homunculus to go to a building called Mist Wall, New York's headquarters of Nebula on the next day and notes there will be a chance that Firo will be there as well as the answers she seeks regarding the Homunculus faction led by Huey.

At the climax of The Slash, he and Ennis manage to arrive at the pyramidal top floor of Mist Wall, confronting Jacuzzi along with Nice and Donny. Isaac and Miria are still charmed by the apparent magic show that was still continuing to take place (wherein the Lamia are conducting a massacre against Nebula employees). The timely arrival of Felix Walken, Chane , Maria and Tick Jefferson causes further turmoil. Ronnie stays in the background and notes Maria's doubting visage, prompting her to ask if she needs his assistance to set things right. Tick lashes at Ronnie to not interefere and allow her to believe in her skill, forcing even the demon to apologize. Maria overcomes her doubts and fears before finally overpowering the now psychotic Adele. Maria's victory prompts Ronnie to syncornize her sword to cut the rainy skies of New York to show a glimpse of the sun, saying that she did well.

"Think of it as congratulations"

Finally, he was able to speak to Jacuzzi and the young delinquent tells Ronnie they will not ally with the Martillos but provide financial payments and offer their allegiances, satisified with the results, Ronnie brings his associates Firo, Ennis, Isaac and Miria back to the Alveare while the morning continues on undisturbed at Mist Wall.

At the books' epilogue, Ronnie teleports to Alcatraz to speak with Huey Laforet and they share their desires and differences. Huey wishes to become a demon like Ronnie while Ronnie wishes to see what humans/immortals are capable of hence his sharing of the Grand Pancea. After a friendly banter, Ronnie warns Huey that Ladd Russo has requested a transfer there and tells him to be careful of the mad hitman's desire to kill Huey. Huey muses this as Ronnie returns back to the Alveare.

Trivia

 * While Ronnie is a demon, he once claimed to be an immortal from long ago that "Knew too much". However, this seems unlikely as while he has many of the abilities that immortals have, such as longevity (he has yet to be seen regenerating), he has also shown abilities that immortals and humans lack, such as psychic abilities and the usage of fake names. Huey Laforet has his own thoughts on the matter; he believes that Ronnie is an omnipotent entity or even a "God" that is existence or possibly immortality itself.


 * While there is a ritual to summon Ronnie, he refers to it as a tedious ritual, and that the throughts of other bring him into their midst. It is possible that Ronnie made the ritual just to see if the Advenna Avis Alchemist were brave enough to attempt to summon him, or that the ritual had another purpose that has yet to be revealed. Another possibility is that Ronnie was already in their midst, but it was the ritual that allowed him to be seen gained solid form or something to that extent.


 * Maiza was about to call Ronnie a certain name when first adressing him, but he was interupted.


 * "Ronnie Schiatto" is a name that he gave himself.


 * Ronnie is apparently an old friend of Celty Sturluson, a main character from Ryoga Narita's other work, Durarara. Both characters share simular traits as well; both are non-human beings capable of superhuman and supernatural abilities, both have lived for a long time without aging and both have allied themselves with the human criminal underworld (Ronnie is a member of the Martillo Camora, while Celty is a deliverer that works for several underground groups delivering goods).
 * Maybe memories of Ronnie do not get passed along when devoured as Firo could not find any memories of Ronnie when he devoured Szilard Quates nor any of the other immortals that the latter devoured. Though it seems likely that Szilard would not notice or care given his single-minded obsessions and the fact that he did have memories of him already and may confuse the two, while Firo does not have memories of Ronnie aboard the Advenna Advis.
