It's been more than three hundred years since the defeat of the Heartless and the Organization. Sora's exploits are remembered only as legend, and his very existence is now questioned as well. In that time, a militant Space Empire called Ivalice has emerged and, using it's superior Gummi Ship armada, is conquering world after world to add to its territory. As the universe falls little by little to this growing threat, a crew of rebels who have proudly taken on the label of Space Pirate traverse the worlds as wanted outlaws who fight against the Empire with their Gummi Ship, the Little Jack. These youths carry with them objects thought to only exist in legend and fairy tale, Keyblades. These "Keyblade Pirates" will have to learn the true nature of their mythical weapons if they are to unlock their true power and find the Ultimate Treasure of the Universe.
