An Oath to Return

"An Oath to Return" is the secret ending of Kingdom Hearts III Re Mind. Unlike previous secret endings in the series, there are two possible endings. The condition to unlock either ending depends on the outcome of Sora's battle with Yozora in the Secret Episode of Kingdom Hearts III Re Mind.

Like, Is Any of This for Real or Not?
If Sora wins, Yozora stumbles backwards and begins to fade away into light. He muses that his powers aren't needed yet, but when Sora is confused, Yozora simply tells him not to mind before fading away, with a slight smile on his face. A light then shines, engulfing all of Shibuya and sending Sora back into the Final World.

Yozora wakes up in a car to his driver, who calls him "commander". The driver asks him if "it" is impressive, to which Yozora looks outside the passenger window and reflects silently. Sora and Yozora both wonder if it was a dream or not. Sora then states that none of this makes any sense to him.

Trivia

 * When Yozora wakes up in "Like, is Any of This for Real or Not?", it is a scene-by-scene recreation of the opening to the  2011 trailer. Kingdom Hearts series creator Tetsuya Nomura was originally the head director for Final Fantasy Versus XIII.
 * In "I've Been Having These Weird Thoughts Lately", Sora crystallizes and blooms into crystal shards before vanishing. The effect is evocative of the "" phenomenon from the  compilation, of which Final Fantasy Versus XIII was initially set to be a part of.
 * The name of the cutscene for both endings, Yozora's and Sora's final lines echo Sora's first lines from the opening cinematic of the original Kingdom Hearts.
