Awakening of the Hero-King: Marth's True Self

Prompt: Write the POV transformation story of the human turning into Marth (from the Fire Emblem video game series), complete with gender change (if the reader is a female), instant clothes change (his/her clothes instantly turning into Marth's outfit from the game "Fire Emblem: New Mystery of the Emblem"), height change, age change, voice change, art style shift (his/her world becoming more anime-esque while he/she becomes an anime-like character), reality change (his/her real world becoming the world of Fire Emblem), and mind/mental change (with his/her personality and memories replaced with Marth's personality and memories, despite his best effort on fighting them off and despite his best efforts on keeping his own memories or personality (he is scared of losing himself and his life/mind/memories), making him forget all about being a mundane person (which was not real), he genuinely remembers that he has always been a hero-king and his name has always been Marth (which is his true selfl)). The transformation is permanent (meaning it its forever) and is completely irreversible. Here is Marth's appearance (according to Fire Emblem: New Mystery of the Emblem); he is a young adult light-skinned (human) man with vibrant blue hair and eyebrows, as well as a handsome face with no beard, mustache, or sideburns. Marth is also athletic with light/slim yet strong muscles, allowing Marth to be an excellent swordsman. He also wears a black and yellow armour on his upper chest and shoulders and the blue cape with a red underside over part of it and his neck, as well as having a bright red ruby that is locked in its place. He has a simple short-sleeved blue robe that is split at the bottom edges, each edge being trimmed with yellow, while the robe's short sleeves are white. A brown leather belt with a small silver buckle is wrapped around his waist to keep his robe in place. A pair of large black fingerless gloves which reaches his elbows fit nicely on his hands. His pants are long and black in color as his brown boots are knee-high with many brown latchings gripping the boots as the tops are flipped over to reveal white undersides with gold encrusted patterns. He also has a gold tiara-like headband/headpiece on his head. Here is Marth's personality; he is a kindhearted, talented, yet incredibly idealistic young man who takes up the sword in the name of his fallen brethren and fellow conquered Archaneans. More than capable as a ruler, he holds himself to an immense sense of duty; willing to push aside his own grief to comfort his Altean people upon their first liberation in the War of Shadows. In sallying forth to aid Princess Nyna, he also honors the historic ties between his country and House Archanea as inducted by his ancestor Anri. Marth's idealism stems mostly from the powerful desire to keep many, if not all of his allies alive throughout his two wars. This is a natural result of Marth's first experiences during his journey began with his elder sister and vassal sacrificing their safety to ensure his escape. Said idealism takes a toll on him, however, as he solemnly visits the graves of those whom have been killed and has mourn the deaths of several figures during the wars. Marth often trusts people without much consideration, which has lead to his near death on two occasions. Nonetheless, Marth's stalwart nature and pleasant demeanor have won the trust and faith in countless individuals throughout his journeys. He has the absolute faith of the platoons of Altean knights he commands and draws respect from countless notable warriors of other nations including Hardin, Minerva, Camus, and Lorenz. Likewise, he has the upmost respect and confidence in his best friend Merric and formed a sibling-like relationship with Tiki. While seemingly aloof, Marth is rather private in expressing his feelings towards others, especially regarding love. It is clear from the earliest scenes of Shadow Dragon that Marth has affections with Caeda, which turns out to be mutual. Marth is concerned with Caeda's safety as a result as she insists on fighting while he fears that she could get hurt or ultimately die. However, her demand to stay close to him causes him to relent and later finds more relief knowing that she is nearby and is one of his most ardent supporters. He plainly states to Nyna that he struggles to find the words and times to express his love, but though her gentle guidance, Marth finally acts upon his feelings and the two admit their feelings at the end of Shadow Dragon with Mystery of the Emblem beginning with the two engaged and later are married at the war's end. Marth has unintentionally wooed other women through his handsomeness and his charming demeanor such as Maria, Catria, and Marisha, though he has eyes only for Caeda. Marth has also been shown to be extremely humble as reflected in his supports, to the point he gets somewhat bashful when complimented by his descendants. In addition, Marth often seeks constant reassurance in his decisions, of which can be seen as both a flaw and a strength, as while it may hinder him at times, but reflects a open-mindedness to others opinions. Once resolved to a cause, he becomes a beacon of inspiration to those who fight alongside him. Marth's legacy ultimately became a legend of a resolute Hero-King that lead the world into an era of peace and prosperity. While the world touted him as a sole legendary warrior, Marth humbly acknowledges that it is only through his countless allies, most notably his shadow left unknown to history, that he was able to achieve his successes and is still nothing more than a mere mortal. The story is that the human is minding his/her own business, but then the world changes around him/her before he/she started to transform against his/her will, completely turning his/her body, height, age, voice, and outfit into those of Marth. Shortly afterwards, his mind becomes swirly as it is becoming foggy or fuzzy, as his personality and memories are being completely replaced by those of Marth, making him both dizzy and scared of losing himself. The voice then echoes in his head, telling him that he is not losing himself, instead, he is waking up from a false life (which the person realized is true), and that this is his true self and that his previous self or life was not real (his previous life and self never was real), being only a dream/daydream, the voice telling him the genuine truth that he had always been a heroic swordsman named Marth, and thus the voice is helping him remember his true self as Marth (which he realized that's his real self), since Marth's kingdom needs him. The voice continues to rewrite his personality and memories, until they had been completely replaced by Marth's personality and memories (which are his real/true memories and personality), making him, now Marth, confused on what was he doing and confused on what just happened a moment ago, being completely unaware of his previous self or life and he is completely unaware that the transformation had occurred moments ago (Marth just passed the weird moment as some headache, a strange daydream while on duty, or some magic-induced illusion caused by some sorcerer), and he knows that he had always been Marth. Once the mind/mental changes complete (which Marth now knows was either just a headache, daydream, or magic-induced illusion as stated before), he is snapped out of that thought and back to reality by his wife, Caeda, who kindly asks if Marth is okay (she genuinely loves Marth, her husband), which Marth confirms that he is okay, knowing that nothing about himself had ever changed, since he is Marth, always had been Marth, and always will be. 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).
