Kairi

Kairi (カイリ) is the main female protagonist of Kingdom Hearts, and the best friend of Sora and Riku. She is a non-playable character in most games of the series, but debutes as a playable character in the Re Mind scenario of Kingdom Hearts III. As one of the seven Princesses of Heart, she is cast adrift from her homeworld of Radiant Garden at a young age as part of Xehanort's experiment to locate the key bearer, which eventually brings her to the Destiny Islands, piquing Sora and Riku's interest in other worlds. In Birth by Sleep, it is revealed that her arrival on the islands is the result of an encounter with Aqua, who gives the four-year-old Kairi a protective charm to shield her from the darkness as well as Kairi gaining the ability to wield a Keyblade after touching the one belonging to Aqua. During Kingdom Hearts, the 14-year-old Kairi's heart is stolen by the Heartless commanded by "Ansem", sending her body into a coma while her heart takes refuge within Sora's. Upon learning her identity as a Princess of Heart and the location of her heart, Sora sacrifices his own heart in order to release hers and return to her body. While Sora disappears, Kairi escapes from a revived Ansem along with Donald Duck and Goofy. Soon after, Kairi finds Sora's Heartless and restores to human form. Kairi later remains behind on the restored Destiny Islands to await Sora's return from this journey.[19] In Kingdom Hearts II, Kairi is approached by Axel to come with her, but she runs away with the help of Pluto and a dark corrider made by Riku. She is soon kidnapped by Saïx to motivate Sora towards acting in the Organization's wishes. She escapes with the help of Naminé and Riku, receiving her Keyblade "Destiny Embrace" from the latter to fight alongside Sora while the former merges with her to become a whole being once again.[20] After Sora and Riku defeat the Organization's leader Xemnas, Kairi reunites with them at the Destiny Islands. In Dream Drop Distance, she is summoned by Yen Sid to train as a Keyblade wielder in order to combat Xehanort's reconfigured Organization XIII. In Kingdom Hearts III, Kairi trains with a reformed Axel in a secret place created by Yen Sid's magic. After completing her training, she reunites with her friends and participates in the final battle against Xehanort and Organization XIII, but Xehanort destroys her body to motivate Sora into helping recreate the χ-blade. Following Xehanort's defeat, Sora departs to restore Kairi by using the power of waking; in the final scene of the game, Kairi is shown to have been revived by Sora before he fades away as a consequence. In the "Limitcut" episode of Re Mind, Kairi is revealed to be in a deep sleep in Ansem's lab, as Ansem The Wise and his apprentices analyze her heart for clues on Sora's whereabouts.
