Part One of Kingdom Hearts II is the opening video.
The video starts out showing Sora at the crossroads before he entered Castle Oblivion. He says "Scattered dream that's like a far off memory. A far off memory that's like a scattered dream. I want to line the pieces up - yours and mine." The scene then moves to show Kairi with her good luck charm on the Destiny Island coast. It also shows a shell, similar to the one Xion turned into, get swept up by the sea. The scene moves to show Sora, Kairi, and Riku on the Paupu Tree talking. Riku and Kairi fade and Sora jumps, the scene changing to the Rising Falls in Hollow Bastion. Sora, Donald, and Goofy fight a ton of Heartless, and Sora runs up some steps, miracusly ending up where Kairi's body lay while they were in Hollow Bastion in Kingdom Hearts. It then shows Riku-Ansem in front of the Dark Depths, the entrance to the world's Keyhole. He turns around and puts out his hand while the screen changes to that of Kingdom Hearts where the wave came threatening to kill Riku. Sora again runs after him, but this time attempting to hit him with the Keyblade. Right before the wave comes down, the scene goes back to Hollow Bastion where Riku attempts to get Kairi's heart out of Sora, but he fails. He is flung back to the entrance to the Keyhole, and strangly turns into Ansem. Sora goes to attack him, but when he does, the scene changes to the light of Kingdom Hearts, killing Ansem. It shows Riku on the other side of Kingdom Hearts before they seal the door.
The scene then changes to Sora loosing his heart. It then shows him hugging Kairi after regaining his heart. The scene then goes to Kairi on Destiny Islands looking at the tree, longing for Sora to come home. It then goes back to the restoration of the islands, and Sora dissappearing in the gigantic ball of light on the other side of the sea.
It then changes to an older version of Kairi looking out onto the water. It then shows Kairi and Namine mouthing the same words. The scene changes to show Namine in Castle Oblivion. It shows her drawing a spiral staircase, and then Sora, Donald, and Goofy going up it, defeating Heartless as they go. At the top, it shows DiZ and another hooded figure. It then shows a hall, and Sora battling Marluxia while Riku battles Ansem. The scene then changes to the staircase again. It shows Sora, Donald, and Goofy on one part while Riku is at another part. It then shows Sora going into Namine's room, and being trapped in the Memory Pod and falling asleep. He rushes across the ocean at tremendous speed. He zooms to the small island. It then shows Namine closing her notebook on an image of Sora.
It shows Sora, Kairi, and Riku holding hands on the island, then Roxas falls through the sand, and into a waterlike substance. He lands on a platform, and then the birds fly away to reveal an image of Sora and his friends. thumb|300px|right|Kingdom Hearts 2 Opening
