The Melodic Metamorphosis: A Tale of Becoming Ferid Bathory, the Enigmatic Vampire of Seraph of the End

Question: Write a POV transformation story of a human reader turning into Ferid Bathory from the Seraph of the End/Owari no Seraph anime series, complete with gender change (if the reader is a female before the transformation), instant clothes change, height change, age progression, art style shift (the reader's body changing from real life-styled to anime-styled), reality change (the reader's real world becoming the world of Seraph of the End), and mind/mental change (with the reader's personality and memories replaced with Ferid's personality and memories, despite the reader's best efforts on fighting off the mental changes, making the reader completely forget his previous self and only remember being a vampire named Ferid Bathory). For Ferid's appearance (after the reader turned into him), he is a tall and slender male (182 centimeters tall) with a rather handsome appearance. He has long, waist-length silver hair with bangs and a lock of hair over each ear. Like all pure vampires, he has red eyes and pointed elf-like ears. He also wears red diamond shaped earrings. Ferid's attire as a noble is composed of several components. He wears a white long-sleeved shirt with a decorative cut. It has a black line with dark gray rhombi intermittently dispersed along it. There is originally a stripe on his left side as well, but this disappears after Krul defeats him. The cuffs off the shirt are black and with a pair of gold colored lines around the wrist cuffs with three buttons. White lace ruffles comes out of the cuffs over his hands. He wears white gloves. Ferid wears a white cape with a decorative cut over his shoulders and arms. It reaches to his waist in the front and down to his upper thighs in the back. The cape has black shoulder details as well as the black vampire insignia on the left shoulder. It also has two black buttons on the right. A gold ring connects to the vampire insignia and is attached to a chain running under his ruffles. There are some gold decorations hanging from this chain. There is a wide dark gray strap beneath this cape moving from his right shoulder to his left hip. This has three strips running down it with a small mark over each stripe at set intervals. The collar is decorated with a scarlet bow at the base of his throat. The tails of the ribbon reach his waist. Two layers of white ruffles are present beneath the bow and reach his mid-chest. Ferid also has a white waistcoat he wears over his posterior. It is split down the center and reaches his mid-calf. It is held in place by a wide black belt with a large buckle. The buckle rests over his left hip. He dons a pair of white pants and black boots, which reach his upper thigh. The boots have three golden buttons at his thigh and three at his calf. The boots are darker at the toes, and heel. A pair of small black ribbons meet over either heel and are kept in place by a small white button detail in the center. For Ferid's personality, he has a courteous manner of speaking and he is carefree when interacting with others. When the opportunity present himself, he will place himself in a physical higher position than those he is speaking to. His pleasant manner of speaking extents to those he murders for Ferid has a deviously sadistic streak. He kept a map around for Mika to find and after waiting for him and his family to reach the exit and escape, Ferid appeared and first enjoyed the loss of hope that he could identify in their faces then set about systematically killing a number of children. His entrapments cover his allies as well, he later reached the point where he said the queen of Japan could not kill him or the progenitor council would learn of her illicit activities. He would include other accomplices in a list of assassination targets he gave to the humans to avoid others suspecting his involvement. In a fight with those who have the means to damage him, Ferid remains largely unbothered. Provoking a vampire much stronger than him and losing an arm did not fully deter him right away although he says losing an arm hurts (he effortlessly reattaches his arm afterwards and is functional again once reattached). On a battlefield he directs units to specific targets but largely observes, only intervening if it requires his capabilities. He blocked an attack aiming for Mika, and antagonized Yu to draw him away from his squad for Mika to get. A scenario such as the presence of the Japanese Imperial Demon Army instilled anger in him and he retreated from that. The story would be that the reader has found a sword (belonging to Ferid) in or around the reader's apartment room or suburban home, and as the reader held the sword, the blinding light engulfed the reader, causing the whole transformation to occur. After the physical transformation, the reader tries his best on fighting off the new memories and personality (such as calling for his friends/family and/or shaking his head in a vain attempt to loose those new memories/personality), but to no avail as he begins to forget his mundane human life and remember his new life as Ferid. Near the end of the story (and long after the transformation ended), Ferid would briefly remember/thought of his previous life as a mundane person, but he soon forgets about it as he knows that he has always been Ferid and he knows that his mundane life as an average human was all just a dream, not reality, and Ferid is content to know that his life as Ferid is the only true life. 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).
