"Spirit of Shadows: The Transformation of Lan Hikari"

Prompt: Write a transformation story of Lan Hikari (from the Megaman Battle Network anime and video game series) instantly turning into Angel Dust (from an adults cartoon/animated series Hazbin Hotel), complete with instant clothes change (Lan Hikari's outfit becoming Angel Dust's outfit), age progression (aging until the reader is biologically somewhere around the 30s), height progression (growing from Lan's preteen height to Angel Dust's 8 foot height), reality change (Lan reader's real world becoming the world of Hazbin Hotel), and mind/mental change (with Lan's personalities and memories being completely replaced with Angel Dust's personality and memories, despite his best efforts of fighting his new personality and memories, making him completely forget he was a normal mortal boy, even forgetting and completely unaware that the transformation that just occurred seconds ago, and only remembered ever being a sinner demon who died as a human man somewhere in 1947, and he remembers being a spider-like demon named "Angel Dust" since his mortal death). For Lan Hikari's appearance, he stands at 142.8 cm and has brown eyes and untidy brown hair, which he keeps out of his face with a bandana bearing the Hikari family mark. His upper-body attire consists of a white long-sleeved shirt with black squares on the elbows under an orange vest. From the waist down, he wears black shorts with yellow stripes on the sides, black ankle-socks, and orange shoes with black stripes. He carries detachable roller blades that allow him to instantly modify his shoes. He will often be seen with his backpack. He almost always carries his PET with him, and the later versions usually come with a pouch or a strap to carry it with. For Lan Hikari's personality, he is outgoing, headstrong, and has a strong sense of justice, though he is often lazy, often sleeping in causing him being late to prior engagements (even if he is the one who set them up), and is a poor student in school, much to Ms. Mari's frustration and despite MegaMan's nagging, though he has the highest grades in Virus Busting. Lan enjoys sports such as soccer and inline skating, which is shown in his preference to skate wherever he goes. He is shown to have a large appetite, often indulging when food is around. As an operator, Lan is able to concentrate in a way he cannot bring himself to do in other situations, and is quick to jump into action to save the day while others panic, even at his own risk. He has a keen sense of deduction, though he often has a simplistic way of looking at things. Despite his aptitude for Net Battling, Lan's ego and arrogance often lead to him making careless mistakes which sometimes put people he cares about in danger. His simple outlook on life also leads to several other problems, such as his emotional vulnerability, which has been exploited. Late in the third game, his vanity and then his trust are both abused in succession, and he is left believing that he is guilty for putting thousands of lives in danger, including his father's, causing him to fall into depression. When he finally arises, his worldview is tempered with a better understanding of evil. For Angel Dust's appearance (after Lan Hikari turned into him), he is a sinner demon who has a slender build (almost mimicking feminine curves, despite being a male) and he stands about 8 or more feet tall, both due to his long torso and legs, as well as his heeled boots. His fur is white and he has a mop of fluffy white hair that extends from both the front and back of his head, with splotches of light-pink across it. He also has a distinctive and focal light-pink heart pattern on the back of his head. The light-pink outline of a heart also encircles his chest, the bottom point of which extends past his waistband and down to his crotch area. His eyelids are light pink and the color extends up to his eyebrows, giving the effect of eyeshadow, and his lashes are dark and thick. His irises are cerise pink. His right eye has a light yellow sclera, his left eye has a dark sclera. He has a wide mouth full of sharp, pointed teeth and possesses a single golden fang that sits slightly to his right of center. He has a New York accent. He has three cerise-pink dots under each of his eyes, which are intended to evoke freckles, although they are actually another set of smaller eyes. He lacks a nose and ears (instead the areas where the nose and ears should be are instead flat-yet-furry surfaces), giving him a less "human" appearance. One of Angel's most noticeable features is his prominent chest. The chest is actually composed entirely of fluffy fur, however, which Angel intentionally pushes up into a breast-like formation with his tightly pinned jacket for show. Angel's everyday attire consists of a long light pink suit-blazer with horizontal white stripes down the length, reddish-grey miniskirt, and long reddish-grey thigh-high heeled boots, accessorized with a reddish-grey bowtie with a cerise pink center and a black choker. On his top set of arms he wears long cerise pink gloves with white detailing at the cuffs, on his bottom set of arms he wears long white gloves. Though, usually seen with six limbs (two legs and four arms), Angel has a third retractable set of arms that he usually keeps hidden but can summon at will (meaning that he can have eight limbs; two legs and six arms). Angel is gay (homosexual), brash, and sarcastic, with a quick, sharp wit, often with bad/strong language (including, but not limited to f-bomb words). He will often use these traits to deflect criticism or insults, and side-step responsibility. He will switch between playful and destructive as he pleases, and his humor tends to be crude and crass, with an emphasis on dirty jokes and innuendos, which he feels is expected of him and actively plays into. He is stylish and performs an excessive amount of confidence with his public persona, being wildly flirtatious and interested in receiving positive attention for his looks and the profile he has made for himself in Hell. He also makes a show of looking down others, declaring the other denizens of Hell to be mostly "ugly freaks". As a result, Angel can often appear flippant and callous. In reality he is preemptively defensive and hides much of his true, more sensitive and insecure, self for his own protection, not expecting those around him to show him kindness. Angel does have friends, and while he cares about them and will sometimes show signs of wanting to reach out, he keeps many walls up between himself and others, being very protective of his true feelings and avoiding holding overly emotional relationships. He holds a cynical view on the idea of redemption, although he seems to still hold onto a small hope it may be possible for him. The ongoing controlling and abusive situation he is in with his boss, Valentino, puts him under a great deal of stress at his work, and he is implied to be somewhat traumatized as a result. Here are Angel Dust's preferences (likes/dislikes); he likes drugs, being abrasive, pranks, getting into scraps, cooking, flirting, the color pink, monetary gain, and Italian food. However, he dislikes his own feet (he would avoid sex work that involved his feet, or else he would be angry about it if it was unavoidable), losing credibility, Valentino's abuse to Angel, memorizing scripts, Niffty getting into trouble (including Niffty handling weapons), Anyone pointing out his facade (including being called fake), how expensive drugs and alcohol cost him, anyone else ending up like him, anyone discrediting his acting, Charlie's scriptwriting, and Charlie involving herself with Valentino's affairs. There should also be quotes from the characters (including but not limited to Lan Hikari or Angel Dust) in this story so we know what they're saying and what they're thinking (including profanities/swears (fuck, shit, bitch, damn, dick, etc) that are used/said by Angel Dust, Vox, Valentino, etc, but not Lan Hikari or other Megaman Battle Network characters since these don't use swearing unlike Hazbin Hotel characters).
