Story
The player(s) visits worlds twice. The default partners are Erde, Strom, and Himmel.

The story begins with Hunter, the Prince of Destiny Islands, having the same dream as his father before him. When he awakens, he discovers to have gained the ability to wield the Keyblade. He goes to his father, Sora, the King of Destiny Island, and his mother, Kairi, the Queen of Destiny Island. They told Hunter that this is a sign that the Darkness is raising again and that they must do something about it. They tell their son to go to the Land of Departure. So Hunter takes the Gummie Ship to the Land of Departure to train to become a proper Keyblade Wielder. The story jumps six months later. During this time, Hunter became friends with Erde, a girl who has great strength, Strom, a boy who is skilled in magic, and Himmel, who is very fast. On day, Sora arrives and gives his son and his friends their first mission as Keyblade Wielders: Go to various worlds, find their hearts which have taken the form of living beings, and protect them from the Darkness. Sora reveals that these beings who bear their worlds' hearts can easily give up those hearts to another or be tempted to yield to the Darkness. If this happens, that world will fall into chaos and darkness. Hunter accepts and he and his friends venture out into the Sea of Worlds to protect the worlds from the Darkness.

Along the way, the four come to learn more about each other and themselves. Especially Hunter, who discovers that his is not technically Sora's son. He's really Sora's clone made with his and Kairi's DNA. They reveal that this was because by the time Sora had finally mange to permanently defeat Master Xehanort, he and Kairi were already past the age of bearing children. However, sometime after Hunter left for the Land of Departure, they learned they were wrong and that Kairi was now pregnant. Hunter, believing that his life was a lie, was heartbroken. When he was alone with despair, he is approached by Young Xehanort who claimed he came to help Hunter get revenge on Sora, Kairi, and their soon to be child for using him as a substitute for something they feared would never happen. At first, Hunter declined, know full well who Xehanort is, but Xehanort tempted him by show Hunter his own worst memories and made him believe that no one loved him. Angered, Hunter accepted Xehanort's offer and became a vessel for Master Xehanort. When he came to Destiny Islands on the day Kairi was due to give birth, Hunter came to kill Sora and Kairi and their child. Sora, refusing to believe his son has become a vessel, tries to use his Keyblade to free Hunter from the Darkness by helping him remember all the good time they had together and letting him know that they really do love him. But just as Hunter was returning to the Light, Young Xehanort comes and convinces Hunter that all those good memories were an illusion. At first, Hunter believes him, but Yuki Villiers, daughter of Snow and Serah Villiers, comes up and embraces Hunter and reveals that those memories are real and that his parents love him and will still love him after their child is born. Hunter then returns to the Light and is no longer a vessel. Angered by this, Young Xehanort engages Hunter in a Keyblade fight which Hunter won and forces Young Xehanort to flee.

After that, Kairi gives birth to hers and Sora's son, Kaze. But later, Young Xehanort steal Kaze and Sora and Hunter to meet him in the Keyblade Graveyard and hand over Hunter or Kaze will be made into a vessel for Master Xehanort. They go to the Keyblade Graveyard where they meet with Young Xehanort and Master Xehanort. Master Xehanort says that Hunter maybe the key to restore the X-Blade as he was made and not born and therefore has a blank heart. If Hunter becomes the thirteenth vessel for the thirteenth Darkness, the X-Blade will be restored. But Hunter refused and demanded that he and Master Xehanort fight for it. If Hunter wins, Master Xehanort must return Kaze, return to the Darkness where he belongs and never return. Master Xehanort agrees, but only if Young Xehanort be the one to fight Hunter as his own powers are growing weaker with age. Hunter wins and Master Xehanort is sent back to the Darkness and Kaze is safe. However, Young Xehanort promises that he will not give up on Hunter until he becomes a vessel.

Sora, Hunter, and Kaze return to the Destiny Island with their friends and family and celebrate Hunter defeating Xehanort and Kaze's birth. Sora tells Hunter that even though he's a clone, he and Kairi will still love him as their son and now Kaze will love him too. He also tells Hunter that Young Xehanort is still out there and Hunter says "We'll be ready."
