Twisted Melody: The Tale of a Lost Boy's Transformation into Crimson

Question: Write the POV transformation story of a male human reader (a boy of 9 years old) turning into Crimson (from the Helluva Boss series), complete with clothes change, age progression, height progression, reality/world change (the reader's real world warping and turning into the world of Helluva Boss), and mind/mental change (with the reader's personalities and memories being completely replaced with Crimson's personality and memories, despite the reader's best efforts on fighting these mental changes and his attempts to call the reader's parents for help, making the reader permanently and completely forget about his past self as a normal human and only remember being Crimson, an imp and a mafia leader). The transformation into Fizzarolli is permanent (meaning it's forever) and completely irreversible. For Crimson's appearance (after the kid reader turned into him), he is a quite tall imp demon, standing closer in height to Blitzo, with white hair, black and white striped horns, and yellow sclera. Around his eyes are white markings, with the right being larger than the left. He possesses a crooked and bent tail with white accents near the base and on the middle of his tail fork. His appearance is similar to his son Moxxie, with similar hair and shape of his horns, however larger and slightly more jagged. Unlike his son (Moxxie), Crimson's skin is a darker shade of red and his legs appear to be plantigrade (like a human's), rather than digitigrade, but still have red cloven hooves (unlike human feet). He also has short-clawed fingers on his hands. All of Crimson's teeth are sharp fangs, while one of his fangs is a golden fang unlike the other teeth (which are white). Crimson's attire consists of a red high-collar shirt that grips his neck, topped by a navy blue coat with light blue accents, thin red stripes, red buttons, and red lining. His pants are dark blue which also have thin red stripes, and his shoes are black and red-heeled dress shoes. He also wears a black fedora with a red and white band. Crimson is a vicious and extremely ruthless crime boss that controls a large army of shark-like demon gangsters. He is horrifically abusive towards Moxxie since his childhood, constantly levying physical and psychological abuse towards Moxxie, and by extension his wife. He cultivates an aura of fear in those that know him, even towards his own family members and close associates like Moxxie and Chazwick. Ultimately, his greed and power come first to him, and he harbors no remorse for his victims. This comes to the point that he appears mentally prepared to kill blood-related family members, such as his wife and Moxxie, to advance his personal goals. Despite this, he is capable of exhibiting a seemingly jovial, warm, happy, and even charismatic presence when he chooses to do so, such as during his initial meeting with Blitzo and Millie, or during moments when he feels comfortable. However, he can be quick to discard this external display of affection as required. For Crimson's preference, he likes smoking, monetary gain, organized crime, mistreating Moxxie, and hanging body parts of his victims as house decorations; he however dislikes anyone who double-crosses him, anyone lesser than him, and anyone talking back to him. There should also be quotes from the characters in this story so we know what they're saying and what they're thinking.
