After Kairi gives him a good luck charm, Sora and his group venture to the End of the World, the remnants of the worlds destroyed by the Heartless, to confront Ansem as he reaches the door to Kingdom Hearts. After a battle, Ansem calls upon Kingdom Hearts to aid him, believing it to be the ultimate reservoir of darkness. However Ansem is destroyed when the door opens, revealing light. Also beyond the door are Mickey and Riku, who help Sora and his friends close the door before Sora and Mickey lock it with their Keyblades from both sides. The worlds lost to the Heartless reconstruct themselves; as the Destiny Islands reform, Kairi returns there while Sora is forced to part with her. Sora, Donald, and Goofy resolve to find Riku and Mickey.
