Keyblade's Owner: Becoming Kairi

Prompt: Write a POV transformation story of a male human reader turning into Kairi (who is also a human) from the Kingdom Hearts game series, complete with gender change (the reader turning from male to female, a pair of feminine breasts grows comfortably on his chest as his body enjoyably becomes more curvy and feminine while his male genitals invert itself enjoyably and painlessly/pleasingly sucks into his body to comfortingly turn into a vagina, ovaries, and uterus), instant clothes change (the reader's outfit instantly changes into Kairi's outfit from Kingdom Hearts III), voice change, height change, age change (either age progressing or age regressing (depending on the reader's age) to become a 15 year old girl), 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 Kairi's personality and memories, as the voice tells the changing reader that she was never a boy and always had been a girl, as well as confirming that she was never a mundane person, since she was daydreaming all this time, and that she has always been a girl and that her name is Kairi, despite the reader's best efforts on fighting off her new memories/personality (she does not want to lose herself and she tries to remember her old name, but to no avail as the voice in her head finishes it for her with the name "Kairi", and that name now fits her and realizes that's her real name), making her fully believe in the voice in her head and know that she had always been a hero and a keyblade wielder, causing her to completely forget her previous self, since that was only a dream and not real, and remembers that she has always been a heroic keyblade wielder named Kairi, which is her true self and true life). For Kairi's third Kingdom Hearts appearance (after the reader turned into her), she is a 15 year old human girl who has auburn hair (which reaches her shoulders), blue eyes, a pale complexion, and a necklace with a silver bead that is only absent when she wears her school uniform. Kairi, in Kingdom Hearts III, has a pink and black dress, black ruffles on one side of her skirt and plaid on the other, with thick belted boots. Here are Kairi's abilities; Because Kairi is a Princess of Heart, her heart possesses no darkness within it, leading to the unique birth of Naminé when she accidentally gives it to Sora, who later sacrificed himself to restore her heart. Should her heart be lost, her body will remain in a dormant state until it returns, as revealed in the first game when her heart was lost. Like the other princesses, she has the power to open the Final Keyhole to Kingdom Hearts (world) in Hollow Bastion once she is gathered with the rest of the princesses. This could be considered as the princesses' main power. Kairi also appears to have some kind of latent magical ability, as seen when she manages to restore Sora's humanity after he becomes a Heartless. However, it could imply that she is only able to restore him because they share the strongest connection. Since the other Princesses of Heart possess the abilities to hold back darkness and upgrade other people's powers, it is no doubt that Kairi can do so as well. Aqua cast a charm on Kairi in the game "Kingdom Hearts Birth by Sleep" so that if she was ever captured by darkness, her light would lead her to the light of another. In an interview, Tetsuya Nomura stated it was this charm that led Kairi to Destiny Islands. Or it could be as a last resort when or if a princess of heart is real danger they can extract their hearts themselves and give them to those they choose to protect it. She additionally has the ability to sense darkness, as the other Princesses of Heart are able to tell Sora of a great darkness nearby. It may also imply to why she was looking ill when Destiny Islands was devoured by the darkness before she disappeared. In the manga, according to Axel, Kairi is able to travel through the Dark Corridor without any negative effects because she is a Princess of Heart. Here is Kairi's personality; she is caring, kindhearted and brave. She is determined and courageous when someone she cares about is in danger, as she always puts herself in harm's way to help Sora when he's in trouble despite the dangers. Kairi's heart is said to be filled only with pure light and goodness, despite darkness and evil residing in almost every heart. Kairi's good heart filled with pure light helped lead Sora back to his true form when he was consumed by the Heartless, and led Sora and Riku back to Destiny Islands when they were trapped in the Realm of Darkness after their battle with Xemnas. Kairi is also very charismatic, quickly befriending Hayner, Pence, and Olette in Twilight Town before being kidnapped by Axel. She's usually always very cheerful and upbeat. Although she has no ability to defend herself in combat like Sora and Riku, she is very brave and strong willed and will put herself in danger anyway to help her friends. Unfortunately, this sometimes results in her needing rescuing by Sora. Near the end of the game "Kingdom Hearts II", she finally obtains a Keyblade of her own given to her by Riku and helps Sora and Riku fight against the Organization. She is currently studying under Master Aqua to continue training with her Keyblade. Probably the biggest part to Kairi's character is her fear of change and the anxiety with it. In contrast to Sora and Riku, who were both curious about Kairi's hometown, she'd rather live on the Destiny Islands with her friends. Kairi even prefers to stay on the islands rather than go to Hollow Bastion. And even so, up to the midway point of the game "Kingdom Hearts II", she stays waiting for Sora and Riku to return. But she is loyal to her friends, and can be rather stubborn sometimes. While the bond of friendship between Sora, Riku, and Kairi is strong, Kairi seems to be particularly closer to Sora than to Riku. This is noticeable when Kairi mentions a change in Riku to Sora in the beginning of the game "Kingdom Hearts" and suggests to Sora that just the two of them leave the island, which she quickly takes back as a joke. Her connection to Sora was strong enough for Kairi to recognize him in heartless form later in the game. Kairi also has a strong connection with King Mickey's dog, Pluto. They met on Destiny Islands, and the she followed him through the dark corridors. Pluto is like her protector as well. It was loving that Pluto went to comfort her at the Organization's dungeon with her responding nicely by petting him. The story would be that the reader has found a keyblade (belonging to Kairi) in or around the reader's apartment room or suburban home, and as he held the keyblade, the blinding light engulfed him, causing the whole transformation to occur. After the physical transformation, the reader checks her private parts and her chest by touching, shocked to find that they had been replaced by their feminine counterparts (with her chest now having breasts and her privates already inverted itself with a wet "pop" noise into her female parts (vagina, ovaries, and uterus)), making her realize in shock and confusion that she was now a girl, even telling herself that. Following the physical changes, the reader tries her best on fighting off the new memories and personality (such as calling for her friends/family and/or shaking her head in a vain attempt to loose those new memories/personality), but to no avail as she begins to forget her mundane life and remember her new life as Kairi. Near the end of the story (and long after the transformation ended), Kairi would briefly remember/thought of her previous life as a mundane person, but she soon forgets about it as she knows that she has always been Kairi and she knows that her mundane life as a mundane person was all just a dream, not reality (meaning her mundane life as an ordinary boy was not real and never was real to begin with), and Kairi is content to know that her life as Kairi 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).
