Kairi

Kairi is one of the main characters in the Kingdom Hearts. She is the original persona of Naminé. Kairi was born in Radiant Garden and currently lives on Destiny Islands along with her two best friends, Sora and Riku. She is four during Kingdom Hearts Birth by Sleep, fourteen at the start of Kingdom Hearts, and fifteen during Kingdom Hearts II. Kairi's name is derived from the Japanese word for "Sea".

Kingdom Hearts Birth by Sleep
Kairi was born on Radiant Garden, where she lives with her grandmother. One day, she is chased by a group of Unversed and encounters Aqua, who senses a pure light in her heart, since she is a Princess of Heart. Frightened, Kairi touches Aqua's Keyblade, unintentionally performing a Keyblade Inheritance Ceremony. As she and Aqua are about to be attacked, King Mickey arrives and Aqua evacuates Kairi before returning to fight alongside Mickey. After the Unversed are defeated, King Mickey and Aqua talk about the light they sense in Kairi's heart, and Mickey suggests that they team up, but is called away immediately afterwards. Kairi then gives Aqua the flowers she picked before the Unversed appeared as thanks for helping her (which becomes the Destiny's Embrace keychain). In return, Aqua puts a protective charm on Kairi's necklace, and tells her, "One day when you're in trouble, the light within you will lead you to the light of another, someone to keep you safe." Kairi thanks Aqua and then returns to her grandmother, who begins to tell her the story of the light and the darkness, while Aqua believes their meeting may not have been a coincidence.

After Terra-Xehanort's defeat, Kairi is seen picking flowers in a large garden. She looks up to the bright sky, looking as if she sensed something. As she does, her necklace emits a weak glow.

Kingdom Hearts
One year after the events of Kingdom Hearts Birth by Sleep, the Radiant Garden became shrouded by darkness and everyone was scattered across the universe. Kairi appears off the coast of the Destiny Islands during a meteor shower; though it is initially believed that Xehanort's Heartless had sent Kairi to the islands as an experiment to test any possible connection between the Keyblade wielders and the Princesses of Heart, her arrival was actually due to the protection spell Aqua had cast on her one year earlier. Sora, then five years old as well, carefully approaches her and asks, "Who are you? Where did you come from?"

Sometime later, Sora and Riku were in the Secret Place and talking about "the new girl at the mayor's house". This provides the player a kind of insight into her origins: Kairi is not a native of the Destiny Islands, and is the adoptive daughter of their mayor.

Kairi later becomes very close friends with Sora and Riku who playfully compete for her attention. She often supports these competitions, although she does not know they were contests for her affection and not just innocent rivalry. She bears no memory of her life before the Islands, and her mysterious past sparks curiosity in Sora and Riku, who are anxious to leave Destiny Islands and see other worlds. This leads the trio to build a raft in the hopes of traveling to other worlds. However, before they can leave, their islands are attacked by the Heartless, and Sora finds Kairi in their Secret Place. She turns towards him, looking sad and a little ill, and then a huge gust of wind sweeps through a door in the back of the cave and Kairi flies towards him. Sora opens his arms to catch her, but she vanishes right as she is about to be swept into his embrace.

During this time, it is speculated that Kairi's heart chose Sora as a vessel and when she passed through him, her heart was left behind in him while her body vanished to some distant world.

She then becomes the game's driving force, as much of the game's story centers around Sora's and Riku's attempts at finding Kairi. However, Riku is hostile to Sora (having been manipulated by Maleficent into believing that Sora no longer cared for either Kairi or himself).

Throughout Sora's journey, he encounters multiple images of Kairi without knowing about Kairi's heart being a part of his. First, when he wakes up in a motel room after his fight with Leon, and sees Yuffie in Kairi's form and mistakes her to be Kairi until she tells him who she is. Later when he visits the Magician's Study behind the door of the Third District, Kairi appears to him and tells him how much the study reminds her of their Secret Place, but she disappears when Goofy calls to him. When Sora crash lands into Deep Jungle, she reappears again for a short moment, right behind Tarzan, then disappears again. Finally, before setting off to Hollow Bastion, Goofy and Donald encourage Sora to believe in himself, then Kairi says from within "I believe in you." before pulling him into one of her lost memories about her grandmother telling her younger self a story about the light. These encounters speculate that Kairi was experiencing Sora's journey from within his heart, including befriending Donald and Goofy.

Riku finds her first, but she is in a comatose state, with a vacant, lifeless expression and a limp body. She'd lost her heart and because of her Princess status, her body remained untouched by the darkness that usually produced a Heartless. With empty promises by Maleficent, Riku was convinced that he alone could locate Kairi's heart and restore her to health. When inside Monstro, Riku attempts to kidnap Pinocchio in hopes to use his heart to restore Kairi's. This act confuses Sora as he hasn't learned of her fate. His attempt fails and he is forced to retreat.

In Neverland, Sora finally encounters her body, along with a painful reunion with Riku; who is very defensive about her and ends up locking her in a room with Wendy so that Sora can't get to her. When Sora reaches the room below her cell, he extends his hand towards her, desperately hoping for a reaction as he is just now discovering the full lengths of Kairi's condition. Unconsciously, her hand twitches before going still again, much to Sora's relief. Riku then takes her away yet again, having new knowledge of where Kairi's heart might be. After the defeat of Captain Hook, Goofy ponders aloud whether or not Kairi had indeed lost her heart, but Donald, not wanting to upset Sora, promptly shushes him. Sora, however, appears to be in denial, pondering over his disbelief that he could fly and whether or not Kairi would believe him.

Their friendship severed for the time being, Sora continues his journey, destined to clash with Riku in the near future once again over Kairi.

Eventually, Sora follows Riku and Maleficent to the world of Hollow Bastion where he too learns of Kairi's fate. However, Ansem, Seeker of Darkness, while possessing Riku, reveals that Kairi's heart has been resting within Sora all along, which explains all the visions he has had of her during his journey. Furthermore, Kairi is one of the Princesses of Heart, a maiden whose heart holds no darkness, and is needed to open the Final Keyhole. He then attempts to take her heart from Sora, but he defends himself to protect it. After winning a fight and driving Ansem from Hollow Bastion, Sora sacrifices himself using the Keyblade of People's Hearts to free Kairi's heart, and is turned into a Shadow Heartless. Awakened as her heart is finally restored, Kairi runs towards him, but as soon as her fingers touch him, he vanishes. Refusing to believe that Sora is gone, Kairi prepares to fight the Shadow Heartless that surround her, along with Donald and Goofy.

However, once Ansem reappears and Riku's spirit stops him from attacking Kairi, she flees. Devastated, she, along with Donald and Goofy, attempt to escape from Hollow Bastion. But just as they are cornered by the Heartless, she recognizes Sora's Heartless from the crowd and manages to bring Sora back from the darkness by embracing him and promising to protect him. The group escapes Hollow Bastion, revealed to be Kairi's home world, and find shelter in Traverse Town where she could be protected by Leon and the others.

Sora finds Kairi in the underground water tunnel after talking with Leon. She states absentmindedly how much this place reminds her of their Secret Place. While lost in darkness, Sora witnessed one of Kairi's memories of her as a little girl wandering around the Hollow Bastion library with her grandmother. Sora mentions this and it is revealed that after her heart was restored, Kairi could remember certain things from her past. Though Kairi wants to help rescue Riku and stop the darkness from emanating, Sora convinces her to stay put, not wanting her to get hurt and also joking that she would be in his way; he also acknowledges that, since their hearts were one, they will always be together. During this conversation, it was revealed that Kairi's voice brought him back from the darkness. Kairi gives in and gives Sora her lucky charm, which doubles as the Oathkeeper.

In the game's final cutscene, she appears on a section of Destiny Islands after Sora's final battle with Ansem, Seeker of Darkness, likely confused. Sora runs up to her, a little too late as the world is breaking apart, restoring all the previously destroyed worlds. Just before she is sent back, Sora promises that he will come back to her as soon as he finds Riku and King Mickey. She is then transported back to Destiny Islands without him, wistfully watching the island regenerate around her with Sora's goodbye still fresh in her mind.

After the worlds are restored, Kairi visits the Secret Place, looking at the pictures that she and Sora had drawn over the years. Once she sees the picture that Sora had drawn of him giving her a Paopu Fruit, she is moved to tears and adds to it; the picture now depicting herself and Sora exchanging two halves of a Paopu fruit. This could be interpreted as a sign that Kairi loves Sora, or simply that she truly does want to remain an eternal part of his life.

Kingdom Hearts: Chain of Memories
Although Kairi did not directly appear in Kingdom Hearts: Chain of Memories, she did play a very important role. She served as a constant figure of light for both Sora and Riku and fervently awaited their return on Destiny Islands.

In Sora's journey, Marluxia ordered Naminé to take Kairi's place in Sora's heart. However, she says that she could never really replace Kairi and that she was only Kairi's shadow. Kairi's image shows up at Destiny Islands when Sora remembers that the one he holds dear to his heart is Kairi, not Naminé. When Sora is about to go to sleep, she tells him that if he remembers "the one most important to him" his memories will restore faster, so Sora looks deep into his heart and finds Kairi.

In Riku's journey, Zexion uses Naminé to torment Riku with an illusion of Kairi, as well as with illusions of Tidus, Selphie, Wakka, and Sora. Naminé also takes Kairi's form to help Riku control the light and darkness in his heart before the final face-off with the devious Nobody.

In the credits for Kingdom Hearts Re:Chain of Memories, Kairi is shown to still be waiting for Sora and Riku's return.

Kingdom Hearts 358/2 Days
Kairi makes a brief appearance in Kingdom Hearts 358/2 Days; after Roxas wakes from his coma on day 49, Xion gives him a seashell. When Roxas puts it up to his ear, a flashback from Kingdom Hearts is shown, depicting Sora and Kairi on a beach looking at the sunset. Later, during Xion's nightmare, another flashback of Kairi is shown as she is waking up Sora. Kairi is also mentioned by Riku and Xion when they were in a conversation on Destiny Islands.

During this time, Kairi is assumed to be living a normal life on Destiny Islands where she waits for Riku and Sora's return, though her memories of Sora are probably vague because of Naminé's interference with her memories. With the two of them away, her only company becomes Selphie, Tidus, and Wakka. Roxas saw a memory of Kairi during a mission in Destiny Islands and remarks that she looks like Xion.

Kingdom Hearts II
Kairi, now fifteen years old, lives her life normally on Destiny Islands. She attends school regularly along with her friend Selphie and has noticeably aged, having longer hair and more defined features. It can be assumed that she has spent most of her time focusing on her studies, thinking about the boy she's forgotten, and hanging out with Selphie, Wakka, and Tidus - all of whom have returned to Destiny Islands safely. She's also become slightly more withdrawn because of Sora's absence, with wisdom beyond her years. She's not as brash and bold as she was in the first game, but she's still pretty sociable. She understands that both Riku and Sora have great destinies and duties to fulfill, but that still doesn't keep her from pondering taking action and searching for them on her own.

She misses Sora, but most of her memories of him have faded away because of Naminé's interfering with his own memories. One day, while walking home from school with Selphie, her heart is put into contact with a young boy named Roxas, later revealed to be Sora's Nobody. It appeared that Roxas was trying to contact Naminé, Kairi's Nobody, and ended up reaching her instead. During this conversation, Roxas brings up Sora, and, when Kairi inquires about his name, Sora himself, despite being in stasis, somehow uses Roxas as a conduit to talk to her, chastises her for forgetting his name, and jokingly gives her a hint ("Starts with an 'S'!"). Soon afterwards, Kairi sends a letter in a bottle out to sea in hopes that it would reach Sora one day, and immediately remembers his name and possibly everything else about him. ("Starts with an 'S'... Right, Sora?")

It is worth noting that this was the only conversation Kairi and Roxas had throughout the whole game.

One day, Axel comes to Destiny Islands and tells Kairi to come with him. She refuses until Axel summons a group of Nobodies. A bark behind her gives her another option. She then runs off into a nearby portal with King Mickey's dog, Pluto, into Twilight Town and meets Hayner, Pence and Olette. She hits it off with them, immediately fitting in with the three and going as far as to explain for whom she is searching. To her joy, Hayner, Pence, and Olette know Sora, assuring her that she could stay in Twilight Town until his next visit.

Unfortunately, she is found again by Axel and forcibly taken by him, Olette, Hayner, and Pence's attempts doing nothing to prolong it. However Saïx finds Axel with Kairi and takes her to the World That Never Was as a prisoner, stating that she is the "fire that feeds Sora's anger." Kairi is devastated, thinking all hope is lost until she is freed by her Nobody, Naminé. Naminé uses a Corridor of Darkness to allow them to escape the cell, telling Kairi to trust herself.

The two's attempt to escape is stopped by Saïx and two Berserker Nobodies who offer to take Kairi to Sora. Once she refuses, Saïx gets ready to send the Nobodies to attack the two girls only to be saved by a cloaked figure. Naminé hints at who the cloaked figure is, causing him to pause as Kairi strides towards him to remove the hood. Her guess is correct and it is indeed Riku even though his appearance has changed to that of Xehanort's Heartless, though she takes this in stride and is just happy to be reunited with Riku. Riku leads her to Sora and is attacked by a group of Heartless. He hands Kairi a Keyblade, and they successfully fend off the remaining Heartless. She is then reunited with Sora with a touching hug between these two. She stops Ansem (Riku) from leaving and shows Sora that Ansem is really Riku.

The three along with Donald and Goofy face off with Luxord and Saïx to get to Xemnas. Kairi is a pillar of support during these battles more than an actual participant - as Luxord's battle leaves them caged by cards and Saïx uses a shockwave to force both her and Riku (using his body to shield her) behind a barrier so he can battle alone with Sora, Donald, and Goofy.

After Sora and Riku defeat Xemnas, Naminé appears and creates a portal, where Donald, Goofy and Mickey go through leaving Sora, Kairi and Riku. Kairi walks towards her and Sora follows Kairi. Kairi thanks her as Naminé tries to make Sora remember her, but Sora gets confused. Roxas comes out of him. Naminé and Roxas accept their fate together to live inside Sora and Kairi as they fuse with their original selves. Kairi walks into the portal, but when Sora and Riku follow the portal disappears and they fight Xemnas again.

After they defeat Xemnas, they arrive at the shore of Dark Meridian. Kairi's letter washes up on shore and Sora reads it. The Door To Light appears and the two boys go through it and arrive at Destiny Islands shores as Kairi shouts for them. Sora excitedly swims towards her but Donald and Goofy jump at Sora first and Mickey jumps at Riku. They hug Sora, then Sora shows her the lucky charm and replies to Kairi "We-We're back!" while Kairi corrects him, saying "You're home" and extends her hand. As Sora takes her hand, he simultaneously returns the lucky charm to her. For a brief moment, Roxas and Naminé are shown smiling back at each other, just as Sora and Kairi are.

Shortly after King Mickey, Donald, Goofy, Pluto, Jiminy, Uncle Scrooge,Huey, Dewey, and Louie return to Disney Castle, Sora and Riku talk about the Door to Light until Kairi appears running to them, shouting their names. Sora turns to her and asks "Hey, What's up?" and Kairi hands him a letter in a bottle that displays King Mickey's seal. The trio immediately open the letter and read it, though its contents are hidden from the player.

Kingdom Hearts coded
The then-fourteen-year-old Kairi appears in a cutscene in Neverland alongside the then-fifteen-year-old Riku on top of the Clock Tower.

During the end of Kingdom Hearts coded, the real Kairi, along with the real Sora and Riku, reads Mickey's Letter, corresponding to the final scene of Kingdom Hearts II.

Blank Points
Sora sits on the Paopu tree while holding the message from King Mickey, staring off into the sunset. After Sora tells Riku that he has made a decision, Kairi walks up to them. Sora tells her that everyone needs him, and that he has to go because he is who he is because of them. She then hands him her lucky charm and tells him that she'll see him soon.

Kingdom Hearts 3D: Dream Drop Distance
Kairi appears four times only in the entire game.The first one is in the opening credits where she is seen with Sora, Riku, Donald and Goofy on Destiny Islands, also showing the events when Kairi loses her heart while their homeworld is consumed by darkness thanks to Ansem, Seeker of Darkness. She appears also when Sora is falling to the Awakening and she briefly transforms into Naminé. The second time is when Sora is chasing the illusions of Riku and Kairi near the end of the game. When Sora reaches them, Riku takes the form of Terra, while Kairi takes Aqua's and Sora himself takes Ventus's form. Motivated by the fear of losing them again, Sora/Ventus chase after their friends, while they return to their original forms. For the third, Kairi appears, again as an illusion, along with other people, when Sora tells both Xigbar and Xemnas how his heart is strongly connected to his friends. In the secret ending, when Goofy and Donald are discussing what is happening with their friends, they are suddenly greeted by Riku, but they are also shocked to see who is with him. After some minutes, while Yen Sid and Mickey are discussing what they must do to protect the Princesses of Heart from Master Xehanort and his newly formed Organization XIII, Riku arrives and tells Yen Sid he has brought the visitor his master asked him. Mickey and Riku gets confused and surprised as they are curious about what Yen Sid wants with their visitor. Yen Sid tells them that he has heard that this person could also wield a Keyblade and he wants to train her so she can better protect herself and others. That person is Kairi.

Trivia

 * Though Kairi and all other original Kingdom Hearts characters are Disney characters, she was featured in Dead Fantasy, a fan-made crossover between popular video game franchises Dead or Alive and Final Fantasy, likely because she was designed by Tetsyua Nomura, who designed most of the Final Fantasy series characters.
 * Kairi is considered by many as the first Disney princess to originate from a video game, though she is an unoffical member of the Disney princess franchise.
