As the computer-generated Sora from the intro of Dream Drop Distance rises, he slowly changes in appearance to a newer, in-game model.

The beach of Destiny Islands is then shown, with the Master's Defender Keyblade lying on the sand. Sora, now in his Kingdom Hearts II attire, approaches it and lifts it, looking at it curiously before shifting his gaze to the horizon. The game logo then appears.

A gameplay video follows, Sora begins running through Twilight Town, wielding the Kingdom Key. He is chased by a swarm of Shadow Heartless and flees, dodging the swarm by jumping off the sides of buildings in a way similar to his Flowmotion abilities from Dream Drop Distance. After riding the swarm in a manner similar to Vanitas riding the Keyblades in Birth by Sleep, Sora turns around and leaps to confront the swarm head on. The screen then cuts to black and reveals that the game is in development.

Afterwards, the video fades to Sora using a "Pirate Ship" and swinging dealing damage to the Heartless below, finally ending with a massive barrage of spinning the boat around.

Gameplay fades into another scene where Sora, Donald and Goofy are on a "Big Magic Mountain" train ride going around the Rock Titan, the camera closes in on Sora then out as Sora attacks the Titan a couple of times before jumping on top of the Titan's hand and landing back onto his seat. The camera closes in on Donald now then back out as Sora attacks the Titan yet again. Sora leads the train upwards into the sky, high above the Titan, turns around facing the Titan and sends the train ride right into the Titan.

E3 2015 Trailer
The trailer opens with a scene of Master Xehanort and Master Eraqus in their youth, playing chess in the Land of Departure. Xehanort asks Eraqus about the ancient Keyblade War, which Eraqus claims is their master's favorite story. However, when Xehanort mentions the "Lost Masters" who actually started the war, Eraqus feigns ignorance, and Xehanort remains unconvinced. The trailer then cuts to gameplay videos featuring Sora, Donald, and Goofy fighting Heartless in Olympus Coliseum, a world based on Tangled, and Twilight Town, with Sora displaying new abilities with the Keyblade.

The trailer cuts back to the original scene, where Xehanort muses on how on the land where the Keyblade War was fought, darkness will prevail and light expire, looking up at the Keyblade that he will one day wield, while Eraqus counters him by claiming that the light might surprise Xehanort and prevail, and Xehanort expresses interest in this possibility. The camera cuts to a close up of their respective king pieces, showing that their game has ended in a stalemate. The trailer concludes by flashing the game's logo.
