Sora, Donald and Goofy travel down a long road that meanders through endless fields, and come to a crossroads. As Sora stands in the crossroads, he gazes up at the night sky and thinks of his lost friends. Just then, a mysterious man approaches from down one of the branching paths. "Ahead lies something you need," he says, "but to claim it, you must lose something dear." The man vanishes before a single path, leading to a castle that eerily resembles a girl’s drawing...In the coming journey, what will Sora and his companions gain, and what will they lose?
