Sora and Kairi are characters in the "Kingdom Hearts" video game series. They are close friends who live together on the Destiny Islands. Through most of the original "Kingdom Hearts" game, Sora spends his time searching for Kairi, who disappears after their home is attacked.
The player controls Sora, the main character, who wields the Keyblade. Sora travels with Donald Duck and Goofy, who are searching for the lost King Mickey. Sora discovers that Kairi is one of the Princesses of Heart, and the main villain needs Kairi's heart to open the Door to Darkness. Sora eventually rescues Kairi, and she returns to the Destiny Islands.
In the English version of the original "Kingdom Hearts" game, Sora is voiced by Haley Joel Osment. Hayden Panettiere provides the voice of Kairi.
