Embracing the Keyblade: Transformation into Riku

Prompt: Write the POV transformation story of the human reader turning into Riku from Kingdom Hearts III, complete with gender change (if the reader is a female, her breasts comfortably flattens to nonexistence as her body enjoyably becomes less curvy and more masculine while her female genitals (vagina, ovaries, and uterus) painlessly and ticklishly inverts itself before enjoyably pushing out into testicles and a penis; however, this is only optional and only if the reader is a female), voice change, instant clothes change, age change (becoming approximately 16-17 years old rather than being older or younger), height change, reality change (the reader's real world becoming the world of Kingdom Hearts), and mind/mental change (with the reader's personality and memories being completely replaced with Riku's personality and memories, as the voice inside his head tells him that he was never a mundane person, since he was daydreaming all this time, and that he has always been Riku, despite the reader's best efforts on fighting off his new memories/personality, making him fully believe in the voice in his head and know that he had always been a keyblade wielder and that his name had always been Riku, causing him to completely forget his previous self, since he knows that was only a dream and not real, and remembers that he has always been a calm, cool, collected keyblade wielder named Riku, which is his true self and true life). For Riku's Kingdom Hearts III appearance (after the reader turned into him), he is a is a tall and muscular teenager with pale skin, bright blue-green eyes and short-cut silver hair. In Kingdom Hearts III, Riku wears a black, hooded jacket that he keeps unzipped, with short sleeves, gold buttons, and a checkered pattern at the hem. Underneath, he wears a pale blue t-shirt with a V-neck. He also wears blue cropped trousers that are hemmed with the same checkered pattern as the jacket, black fingerless gloves on each hand, and black high-top boots. Here is Riku's personality; In the game "Kingdom Hearts", Riku is a calm, cool, collected teenager who is not afraid to push the boundaries. This is illustrated by his lack of fear while stepping into the dark portal during Destiny Islands' demise. His exclamation of, "I'm not afraid of the darkness!", further illustrates this point. During Kingdom Hearts in particular, Riku has a strong competitive streak. He shows his competitive side when he challenges Sora, saying that his heart is stronger than his friend's. Due to the influence that Maleficent has on him, Riku also becomes increasingly jealous of Sora. When he realizes that Sora has acquired new friends in the form of Donald and Goofy, Riku feels that he has been replaced. His jealousy grows when he learns that Sora owns a Keyblade. This jealousy results in numerous fights with his former friend throughout "Kingdom Hearts", and opens the door for Ansem, Seeker of Darkness to possess him. He eventually snaps out of it and feels tremendous guilt and remorse for all he had done. Though his traits are not akin to those of a protagonist in "Kingdom Hearts", he becomes more heroic in the game "Kingdom Hearts: Chain of Memories". During his time spent in Castle Oblivion, Riku begins to confront the darkness which lingers within his heart. At first, he rejects it. However, as the story progresses, Riku realizes that it is possible to use the darkness to achieve his goals. He matures immensely during this period, and leaves behind some of his less likable personality traits. Riku had been curious about what lay outside of his world ever since his early youth in the game "Kingdom Hearts Birth by Sleep". Over time, his curiosity turned to obsession, and he began to think of his world as a prison surrounded by water. This obsession appears to have diminished throughout the year of Sora's slumber, most likely because he had by then travelled to a number of worlds. When he returns to Destiny Islands in the game "Kingdom Hearts II", he still comments that it is a small world, but agrees with Sora's remark that it is only a part of one that's much bigger. Riku later stated that the real reason he wanted to explore outside of his home world was because of Terra. A positive personality trait demonstrated by Riku is a strong desire to protect his friends. Examples of this would be his sacrifice to protect Sora from Xemnas' attacks during their final battle in "Kingdom Hearts II", and his willingness to accept the darkness in order to subdue Roxas in the game "Kingdom Hearts 358/2 Days". Though Riku matures significantly over the course of the series, he retains some of his more youthful personality from "Kingdom Hearts", particularly his sense of humor; he refers to Sora, Donald, and Goofy as "wise guys" when talking to the Emperor, cracks a joke about Donald and Goofy's intelligence at their expense ("Sora never did pick the brightest friends") indicating he saw his previous envy of the trio from the original game was pointless and calls Sora a "total sap" when going to confront Xemnas. Here are Riku's abilities; Already a strong and skillful individual as a child, Riku was always the strongest child on Destiny Islands even before awakening his ability to wield a Keyblade. Tidus remarked that he, Wakka, and Selphie were defeated by him even after they triple-teamed him and it seemed even at that time only Sora could challenge and surpass him. He is already an excellent swordsman and able hand-to-hand combatant, performing quite fast and athletic-related combos, with an athletic springing kick if knocked down. Over the years, as he acquires and continues to develop his skill with the Keyblade and gains the powers of both darkness and light, Riku's level of strength has increased greatly. What first started from him only being slightly stronger than he was with Soul Eater soon grew to levels where he became among the most powerful bosses in the first game and in Chain of Memories, his increase steadily becomes greater, at first fighting the weak Organization XIII member Vexen to a standstill before quickly becoming able to fight and exhaust Lexaeus, although he lost the fight due to his eagerness, defeat Zexion and even overpower Ansem. In "358/2 Days", he trounces Xion rather easily and even holds his own against the full-power Roxas, even eventually briefly knocking him out, but was quickly overpowered once he allowed Roxas to regain his extra blade, forcing him to use the powers of Ansem, at which point he easily dispatched Roxas, although due to him catching Roxas off-guard, and overpowered Saïx and forced him to flee quickly. Although he lost the boost after the explosion of Kingdom Hearts stripped him of the darkness, Riku is still easily the strongest ally Sora can have and aids him effectively in defeating Xemnas powered by Kingdom Hearts. Riku is also shown to be skilled in hand to hand combat, as shown in "Kingdom Hearts 358/2 Days", in which he knocks down a charging Xion with a single punch after dismissing his Soul Eater weapon and while using the powers of Ansem, easily blind-sides and pins Saïx bare-handed. The story would be that the reader has found a keyblade (belonging to Riku) in or around the reader's apartment room or suburban home, and as he/she held the keyblade, the blinding light engulfed him/her, causing the whole transformation to occur. After the physical transformation, and if the reader was a female before the transformation, the now-male reader checks his private parts and his chest by touching, shocked to find that they had been replaced by their masculine counterparts (with his chest now being flat-chested and his privates already inverted itself with a wet "pop" noise into his male parts (testicles and a penis)), making him realize in shock and confusion that he was now a boy, even telling himself that (however, this is only optional and only if the reader was female before becoming Riku). Following the physical changes, 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 life and remember his new life as Riku. Near the end of the story (and long after the transformation ended), Riku 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 Riku and he knows that his mundane life as a mundane person was all just a dream, not reality (meaning his mundane life as an ordinary person was not real and never was real to begin with), and Riku is content to know that his life as Riku is the only true/real 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).
