Anyway a little over view on the story/plot.
The story is about Sora and Kairi's Daughter, Kaizume (Kai), and how she is in love with Riku. All her life she has been told stories about the Outside World, and she has always wanted to go explore, especially if it could be with Riku. Her three elders agreed, but only when she was older. But when new creatures arise, and Riku tells both of Kai's parents, they demand that she not go. When Riku is preparing to leave from the Island, Kai sneaks out. The creatures appear and she is taken to the Chamber of Awakening, where she learns that the Keyblade has chosen her. But when she regains consciousness, she's not on Destiny Islands anymore.
