After sealing away the Door to Darkness, Sora, Donald, and Goofy continue to search for Riku and King Mickey. They travels lead to Castle Oblivion by a man in a black coat, only to lose their memories as they stepped inside the castle, thus the man created worlds from Sora's Memories, their adventure led them to Traverse Town, where the Leon, Yuufie, Cid, and Aerith taught Sora how to use cards in battle against the forces of darkness. Aerith then told him to beware of false memories.
He then was greeted again by the man in the black coat, and another man known as Axol, who wish to test him in battle, thus gaining a set of five cards that led him to five different worlds:
Agrabah where he helped Aladdin defeat Jafar to save Princess Jasmine yet again;
Monstro where they freed Pinocchio and Geppetto yet again:
Wonderland where they battled against the Queen of Hearts and saved Alice yet again;
Olympus where they helped Hercules defeat Hades yet again;
and Halloween Town where they helped Jack defeated Oogie Boogie yet again;
That's when they battled against a woman in another black coat known as Larxene who tested Sora and his friends and gave him another set of four cards, in the worlds that followed:
Atlantica where they defeated Medusa yet again;
Hollow Bastion where they defeated Maleficent yet again;
Neverland where they defeated Captain Hook yet again;
and the 100 Acre Wood where they helped Winnie the Pooh and his friends yet again.
Then they were greeted by another man in a black hood who gave him the Card to Twilight Town where they defeated the man for the first time.
Then the final world was the Destiny Islands where they battled against the Heartless yet again and saving Sora's home island, only to discover that the false memories are starting to take shape by a witch named Namine, who the people in the black hoods were using to make Sora a puppet. Only for Sora to confront the ringleader Marluxia. Sora then came to a desicion for Namine to repair the memories that she had warped to remember his friends.
Meanwhile in a similar pattern, Vexen, Lexaeus, and Zexion were trying to halt Marluxia and Larxene from using Sora as their puppet by using Riku's darkness, but both sides, save Axol, were eliminated, and Sora slept to repair his memories and Riku went to the Road to Dawn and battled against Number XIII, Roxas, saving all from darkness while Roxas goes on a journey of 358/2 days in Organization XIII, losing his friends Xion and Axol and sent to a digital version of Twilight Town.
