Sora stares at his Keyblade, wondering if it's a sword or key when the mysterious voice tells him that is the power within him. The Darkness surrounding Sora shatters and he collapses on a small remain of his island. He struggles to rise and spots a Darkside towering over him. The enemy fires a beam from the heart-shaped hole in his heart, but Sora manages to avoid the blast yet the force of it throws him into the air. The mysterious voice tells Sora not to be afraid and he regains his balance, landing on his feet. He questions what is happening as Shadows begin to rise and, left with no other option, decides to fight. He battles an endless horde of Shadows and proclaims his experience through sword fighting with Riku. He decides to go after the Darkside as it slams its hand onto the ground, shooting Sora back. Sora wonders how he can face a giant enemy when the voice advises him to aim for its eyes. As Darkside retracts his hand, it is surprised to spot Sora using the hand to propel himself upward. Sora shouts at the Darkside that its face is wide open and strikes the Darkside's head, defeating it with a single blow.
