Kairi

Kairi (voiced by Hayden Panettiere) is one of the several main characters in the Kingdom Hearts franchise. She serves as Sora and Riku's best friend, and is Sora's main love interest. Kairi, along with her friends, wanted to see new worlds. One night, the island was attacked by creatures called the Heartless, and Kairi's heart chose Sora as a vessel. Eventually, Sora learned that she was a princess and that her heart is in him. He was able to free it by using the Keyblade of People's Hearts, but became a Heartless as a result. Kairi was able to bring Sora back by protecting him from other Heartless. When Ansem the Seeker of Darkness was defeated, and the Door to Darkness was sealed, Kairi is transported back to the iland, where she now waits for him...
