A Mirrored Reflection: The Transformation into Alastor's Twin Brother

Question: Write the POV transformation story of the human reader turning into an identical clone of Alastor (from the adults animated series Hazbin Hotel), complete with gender change (if the reader is a female), clothes change, age change, height progression, and mind/mental change (with the reader's personalities and memories being permanently and completely replaced with Alastor's personality and memories, despite the reader's best efforts of fighting the new personality and memories, making him/her completely forget about his/her past self and only remember being Alastor the Radio Demon). For Alastor's appearance (after the reader turned into his clone), he is a slim (unnaturally thin), dapper sinner demon with beige-colored skin, and usually has a broad smile full of sharp, yellow teeth. He is approximately 7 feet tall. He sports a pinkish-red cropped, angled bob-cut with black tips at the ends and two large, black tipped tufts of hair extending from the top of his head, evoking the ears of a deer. The style has an undercut at the back, and two small black antlers protruding from the crown, which can grow in size in his full demonic form. Alastor's eyes have dark-red sclerae, bright-red irises and thin black pupils (which can change into the shape of radio dials when shifting into his full demon form). His forearms and lower legs fade to dark grey, and he has red hoof-toed feet and red clawed fingers. Alastor wears a red pinstripe coat with dark-red lapels piped with white, which is ragged along the bottom hem. Underneath this he wears a bright red dress-shirt with a black cross on the chest, and long black dress pants with matching bright red cuffs. He also wears a dark-red oval-shaped monocle, rimmed with black, over his right eye. He accessorizes with a black knotted bowtie with a bright red center, black gloves with red at the fingertips, and black pointed-toe boots with red deer hoofprints emblazoned on the soles. Alastor also carries a thin cane with a sentient vintage style microphone attached to it, which he uses to play sound effects and broadcast his voice. Alastor stands out from many of the more chaotic residents of hell for his well maintained amiable persona. He gives the first-impression of a good-natured and charming man, wearing a permanently wide grin on his face at all times. Alastor's behavior, mannerisms, and even his voice are similar to an old-fashioned radio announcer and speaks with a transatlantic accent, often using quaint anachronisms such as "the picture show" and refers to Charlie as a "charming demon belle". This playful dandyish exterior, however, obscures a much darker side to him - one with high levels of self-importance - and he will not hesitate to use physical violence when others don't act in line with his very particular values or expectations. The story is that Alastor is getting sick and tired of being viewed as an evil monster, and to his dismay, the human reader views demons (who he/she is afraid of) as nothing more than pure evil monsters. So Alastor (by some supernatural means and to teach the reader a lesson (plus he wanted a twin brother)) briefly left the series' Hell and into real life to kidnap the reader and sent him/her to the world of Hazbin Hotel before using his supernatural magic at the reader which turned the reader into his clone in both body and mind (despite the reader's efforts of fending them off), thus permanently turning the reader into Alastor's identical twin brother. The transformation is permanent (meaning it is forever) and is completely irreversible. There should also be quotes from the characters in this story so we know what they're saying and what they are 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).
