You to Male Rosie Transformation: Hazbin Hotel Story

Prompt: Write the transformation story of a male human reader turning into a genderbended version of Rosie (from an adults cartoon/animated series Hazbin Hotel), complete with instant clothes change, height change, 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 and 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), and he remembers that he was and always had been a sinner demon, 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 demon who stands taller than Alastor and about the same height as his twin sister Rosie (about 7.2 feet tall), being a slim, dapper sinner demon with pale gray skin and a mouth with thin black lips and sharp light pink teeth. 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, 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 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 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. 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. 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).
