Your True Self and Life as Rosie's Twin Brother of Cannibal Town

Prompt: Write the transformation story of a male human reader turning into a genderbended/male version of Rosie (from the adults cartoon/animated TV series Hazbin Hotel), complete with instant clothes change, height progression (growing from 5.7-6 feet tall to 7.2 feet tall), age change, reality change (with the reader's real world warping and turning into the world of the Hazbin Hotel series), and mind/mental change (with the reader's personality and memories being completely replaced by the personality and memories of the male version of Rosie, despite the reader's best efforts on fighting off his mind/mental changes and his fears of losing/forgetting himself, making him completely forget that he was ever human just a minute ago and entirely forgetting about everything that had happened moments ago, knowing it to be a strange daydream (being human just seconds ago was impossible since he knows that he was not human ever since his death in the early 20th century (sometime around the 1920s), having died at the same time and place as his sister Rosie (when they were both humans) before arriving in Hell as sinner demons), and he remembers that he was and always had been a sinner demon since 1920s, being a twin brother of his sister Rosie, and his name had always been similar to Rosie (albeit a male version of it), which is his true self). The transformation is permanent (meaning it is forever) and is completely irreversible. For the male version of Rosie's appearance, he is a very tall and slender man who stands taller than Alastor and about the same height as his twin sister Rosie (about 7.2 feet tall), being a slim, dapper-esque sinner demon (more specifically a cannibal demon) with pale gray skin and a mouth with thin black lips and sharp light pink teeth. Like his sister Rosie, he also has dusty-pink cheeks (although not as visible as those of his sister Rosie), white-and-gray hair with pink streaks (which the pink streaks are not as visible as Rosie's), and like all residents of cannibal town (who are also cannibal demons), his eyes are pitch-black with no irises or pupils and he displays no physical evidence of having a nose. Like other Hazbin Hotel and Helluva Boss characters (and unlike real life humans), he only has four fingers (a thumb and the other three fingers). Like Rosie's clothing, his clothing suggests high-class fashion of the Victorian era, which consists of a large, pimped-out sun hat (which resembles a top hat unlike his sister's hat) that is colored in a shade of maroon, with two skulls that are colored in a grayish-pink and red-pink, three dark burgundy flower-like decorations located at the brim, and large plumes which are black and pink-red respectively. Unlike his sister's hat, his hat does not have pink frilled-trim around it, however, his hat also has black lining inside like his sister's. He wears a pale-maroon and pale-burgundy outfit, like his sister Rosie; however, his outfit is made for a man's, being a pale-burgundy sleveless pinstripe coat (without stripes) with black lapels and two buttons running down the middle. Underneath this he wears a long-sleeved pale-maroon turtleneck dress-shirt with a black line running down on the chest as well as black cuffs, and he accessorizes with a black bowtie on the top of his dress-shirt shirt. He also wears long pale-maroon dress pants with matching thin black cuffs and a pair of black short-heeled dress shoes, each with a pale-maroon stripe on the center and the shoes' toes being pale-maroon in color. Here are the skillsets of a male version of Rosie (which are exactly like those of his twin sister Rosie); Cooking (one of his hobbies is cooking: he and his sister Rosie's Emporium serves pieces of Demons for the cannibals to eat, which he and Rosie herself may prepare), Musical talent (he is adept at singing), Charisma (he helped advise Charlie Morningstar on how to help the residents of Cannibal Town understand Charlie's message when Charlie was struggling at giving her speech effectively), Intelligence (he displays some intellectual capability and strategic thinking alongside his (and Rosie's) leadership ability. This is shown with his and Rosie's alliance with Alastor, as they both offer him the opportunity to make a deal with a demon who cannot control their territory after hearing about it. He and his sister Rosie even saw potential in Charlie's abilities which he, Rosie, and Alastor think will benefit them in the future), and Leadership (As an Overlord as well as one of the two leaders of Cannibal Town alongside his sister Rosie, he has some leadership skills that motivate and easily control the residents of Cannibal Town, especially gaining respect from the residents, even from a difficult one; Susan). Here is the personality of a male version of Rosie; Like his twin sister Rosie, he appears as a very capable, articulate, and friendly demon with a sense of elegance and vintage flair to her. He, like his sister, enjoys old-fashioned things, such as old-fashioned music and fashion of the early twentieth century. Just like Rosie (his sister), he displays a strong sense of composure most of the time. In the episode "Scrambled Eggs", he and his sister were shown to have been quiet during the meeting organized by Carmilla Carmine between her fellow Overlords to discuss the new schedule for the Extermination. Like Rosie, he quietly, but respectfully acknowledged his fellow Overlords as they went to the meeting room. When Velvette revealed the severed Exorcist head, he (like Rosie) was shocked at the revelation, but otherwise kept quiet as he observed Velvette argue with Zestial and Carmilla about what to do about it. Just like his sister Rosie, he seemingly agreed with Zestial's idea to not rush into a war against Heaven based on the simple proof that it is possible for Exorcists to be killed, showing he favored caution over Velvette and the Vee's arrogance and overconfidence. Despite his patient attitude throughout most of the meeting, he, like his sister Rosie, would show shock and some outrage as Velvette repeatedly disrespected her fellow Overlords, suggesting he can only tolerate so much before the offense comes at the expense of his associates. More of he and Rosie are explored in "Hello Rosie!", where he and Rosie presents themselves as gracious and charming when interacting and socializing with others. Among the residents of the Cannibal Town, he, like his sister Rosie, is gracious and kind to the cannibals who who visit his and Rosie's Emporium, offering advice or his or Rosie's personal assistance in solving them. Later, after warmly greeting Alastor, he and Rosie politely greeted Charlie and wasted no time in being a gracious host, giving her (Charlie) a place to sit and rest and offering to give her (Charlie) food before agreeing to hear her problems, showing his and Rosie's friendliness and graciousness. Like his twin sister Rosie, he is especially kind and loving to those he considers his friends, such as with Alastor, whom after meeting up with him again after his "sabbatical", he eagerly greeted him as a friend. After meeting Charlie and taking a liking towards her, he and Rosie kindly offered to hear her out her (Charlie) dilemma and repeatedly gave Charlie suggestions on how to overcome them. During this conversation, both he and Rosie were very empathetic and understanding to not only to Charlie, but also to Vaggie, whom the twins (Rosie and her brother) correctly deduced was ashamed of her (Vaggie) past and didn't want to reveal it to Charlie in fear of being rejected by her. Due to Rosie's and her brother's past experiences, they believes that words are cheap and only action is what ultimately shows the truth, particularly when Rosie and her brother remarked that Vaggie trying to make up for her past actions by helping Charlie was telling of Vaggie's love for her. However, despite the twin's general kindness, Rosie and her twin brother are shown to have a dark side as Overlords. Following the latest Extermination, he and Rosie weren't particularly sensitive to the death of their associate, Franklin, as both Rosie and her brother are seen crossing off his (Franklin) name on their sign for Franklin and Rosie and her brother, seemingly without a care (crossing out Franklin's name is a hint that Franklin likely perished during the extermination). Like his sister Rosie, he is also highly intelligent and cunning, as shown where he and Rosie had intimate knowledge on the territorial disputes in sections of Pentagram City between the various demon factions of the city. Like his twin sister Rosie, he himself can also be quite commanding and intimidating towards the cannibals when he wants to be and can lead them efficiently as one of their leaders (along his sister Rosie), being fully aware of the mentality of the cannibals and offered Charlie sound advice on how to properly appeal to them to get them to help Charlie herself. Alastor himself attributes Cannibal Town's relative peacefulness and pleasantness, especially when compared to the rest of Hell, is due to Rosie's and her brother's excellent leadership. Rosie and her brother likewise collaborates with Alastor to ensure their mutual success as Overlords, as seen when Rosie and her brother offered Alastor information regarding a slot of territory he (Alastor) could easily take over with the right deal. Later, after Charlie successfully convinced the cannibals of Cannibal Town to help her, Rosie and her brother took note of Charlie's charisma and the immense power she (Charlie) inherited from her father (Lucifer Morningstar), agreeing with Alastor that taking her side would ultimately be beneficial for them both in the future. Like his twin sister Rosie, he also indulges in the morbid environment of Cannibal Town, being nonchalant and even friendly about its cannibalistic tendencies along with he and his sister's Emporium selling numerous cannibalistic treats. Like Rosie, he even casually offered to feed Charlie a demon leg and some pinky fingers as hospitality to Charlie when she arrived at he and his sister Rosie's Emporium. The story is that the reader is minding his own business, but then the world literally starts changing to leave him in Cannibal Town (a city located in the Pride Ring of Hell, as depicted in the animated series "Hazbin Hotel") before he himself started to change; his body became 2D-animated like all Hazbin Hotel characters with his art style changing from live-action to those of a Hazbin Hotel animated character, while his skin bleaches itself to a pale gray in color with faded dusty-pink cheeks, as his hair bleached itself to a white-and-gray color with faded pink streaks before restyling itself to a bob-styled hair, as his nose flatten to nonexistence to leave the area where the nose once was flat and smooth, while his eyes becomes completely black like all other residents of Cannibal Town, as his teeth grew and sharpened to fill his mouth with sharp light pink teeth as his voice changes to become more elegant and refined, while his fingers reduce to just four (a thumb and three other fingers) to match those of other characters of the Hazbin Hotel characters, as his height progresses from a normal 5.7-6 foot height up to a new 7.2 foot height, while his body becomes slimmer to fit his newfound sense of elegance, as a large pimped-out sun hat resembling a top hat that is colored in a shade of maroon with two skulls that are colored in a grayish-pink and red-pink three dark burgundy flower-like decorations located at the brim and large plumes which are black and pink-red respectively appeared on his head out of nowhere, as every part of his clothes morph/warp into a Victorian-styled pale-maroon and pale-burgundy high-class fashioned outfit consisting of a sleveless pinstripe coat (without stripes) with black lapels and two buttons running down the middle with a long-sleeved pale-maroon turtleneck dress-shirt underneath that has a black line running down on the chest as well as black cuffs, and accessorized with a black bowtie on top as well as having long pale-maroon dress pants with matching thin black cuffs and a pair of black short-heeled dress shoes (each with a pale-maroon stripe on the center and the shoes' toes being pale-maroon in color). His personality and memories also begins to change, with his personality becoming more elegant, capable, articulate, and friendly, despite himself becoming demonic, as the memories of his previous self start disappearing to be fully replaced with new ones of being once a mortal human man (with a similar name to "Rosie" but a male version) who lived with his twin sister Rosie, having lived through the Victorian era, before they both tragically died and manifested as sinner demons, both of them having become leaders of Cannibal Town since then, as well as loving to consume the flesh of lower-ranking demons due the being a cannibal demon (that memory makes the reader horrified and doesn't want to become a cannibalistic monster, but now the reader is, against his will, beginning to love the taste of demon flesh due to his newfound cannibalistic nature just like Rosie (making him ask himself in horror on why does eating flesh sound/taste delicious (he is genuinely scared of the newfound joy of eating flesh since he doesn't want to become a killer or a monster), but he cannot help himself from enjoying the idea of eating flesh and he starts to embrace his newly-cannibalistic nature), which he remembers both he and Rosie enjoyably eating lesser demons' flesh together), and eventually befriended Alastor (once Alastor died as a human in 1933 and arrived in Hell as a sinner demon and a powerful Overlord nicknamed "The Radio Demon"). The reader tries his best to fight off the mind/mental changes occurring within him (even telling himself to not forget), even hoping that this is just a nightmare (bad dream) and he would wake up (but sadly for him, this is all real), as he's terrified of losing himself (as well as his name) to this new identity (which is replacing his own) and he asks himself on what's his name (but he no longer could remember his previous name and can only remember his new name, which is now similar to Rosie's but a male version, causing him to call/refer himself that name instead of his previous name despite his efforts to remember or say his previous now-forgotten name), but he couldn't fight back the mind/mental changes since he is completely helpless against this and he gives in, he is remembering his true self and life, the one that he was always a twin brother of Rosie (who is his twin sister) and he knows that he, along with his sister Rosie, had always been leaders of Cannibal Town since the 1920s (after they died as humans), as well as both he and Rosie having always owned an Emporium in Cannibal Town, and he is happy about this realization (and is happy that he was never someone ordinary), even realizing (or rather knowing) that he was simply daydreaming a moment ago (which he daydreamed on being a plain and average person a minute ago, but he couldn't remember that nor remember on anything he daydreamed just seconds ago, since that daydream just vanished just before the mind/mental changes ended, making him realized that he had always been Rosie's twin brother who always worked and loved together). His mind clears up and he realizes that he is in the Emporium that both he and Rosie owns, before Rosie asks him with concern on is he okay (since she loves him as her brother, much like how he loves Rosie as his sister), with him answering yes in a polite and elegant manner and saying that nothing is wrong, making Rosie relieved that her twin brother is fine. After that, he and Rosie continued on their daily lives in Cannibal Town (even serving severed demon body parts for the residents to eat) as usual (Rosie's twin brother knows that, ever since his and Rosie's human deaths in the 1920s, he has always been this way as a sinner demon who lead Cannibal Town with his sister). There should also be quotes from the characters in this story so we know what they're saying and what they're thinking. Also, it is a POV reader story, so it should not be in an author's point of view (my, I, mine, etc), and it should be from the point of view of the reader (you, your, etc).
