Through countless adventures across many worlds in his long battle against the darkness, Sora, once a little boy who only dreamed worlds beyond his island even existed, has grown up to a dashing young man. Now he is realizing that that battle has played out exactly as Master Xehanort had planned, and the second Keyblade War, the final struggle between light and dark, looms ahead. To counter the overwhelming darkness, Sora and his friends must gather the seven guardians of light. His best friend Riku and King Mickey seek out a battle-scarred Keyblade wielder, while Sora, Donald, and Goofy set off on a journey to find "the Key to Return Hearts." Never-before-featured Disney worlds set the stage for another daring adventure to save the universe.
