Another side, Another story...

"Another side, Another story..." is a "secret movie" seen after the ending of Kingdom Hearts if the player accomplishes certain tasks. The concept was later expanded in a later video, "Another Side, Another Story [deep dive]".

Requirements
To see the movie, the player must have completed the Hades Cup, found all 99 Dalmatians, and sealed every Keyhole, including 100 Acre Wood, or complete the game in Expert mode.

Synopsis
During a rainy day, a black-hooded male walks in a city which closely resembles 1933 New York City. Neoshadows rise from the ground, many surrounding the unknown male. The camera shifts, showing another male in a black coat, but blindfolded and on top of a tall building. To defend himself, the original unknown pulls out the Oblivion and Oathkeeper Keyblades. The blindfolded male looks to the sky, where clouds part to reveal a meteor shower. A purple, glowing heart shape surrounds the Keyblade wielder. The blindfolded male takes off his blindfold. The Keyblade wielder asks a question: "Where's Sora?"

The screen blacks out, and quotes fly by, ending with "We'll go together". A flash, then the words "Kingdom Hearts" appears. It fades to a beach where a female witnesses a meteor fall.

Application to Kingdom Hearts II
"Another side, Another story..." was meant as more of a concept trailer, showing whatever ideas Nomura had for a sequel at the time; it is meant to be taken as an actual part of the storyline for the games. Nojima, the scenario writer, explained that, after the story for Kingdom Hearts II was written, he had to go back and find places to put in the seemingly random quotes found in both "Another side, Another story..." and "Another Side, Another Story [deep dive]" The idea of the Keyblade wielder was affixed to Roxas, and the blindfolded male is Riku.
