I don't know wheather or not this is plasuble but its worth a shot.
what if according to the refrence
The heart and soul are seperate, and when the body is cast off from the heart, the body and soul disappear. This is not the end though. It is sent to another realm. It becomes a new existence. A you other then yourself. An existence of neither light, nor darkness, a mere shell of what you were, begrudging both the light, and the darkness. An in-between existence. But since we exist here, they cannot also "exist". Based on this, they have been named, "The Non-Existent Ones". The only guarenteed N.E.O that has been seen is the mysterious figure known as the Enigmatic Man, or simply the Unknown Enemy. He confronted the Keyblade Master, Sora in order to test his power.
maybe when the Keyblade master is chosen their Body and Soul seperate from their heart thereof making the Enigmatic Man, and Glowing Eye Unknown for sora's body and soul. and the Blindfolded Unknown, and Blonde Haired Kid for riku. this would make sense because riku and sora were best friends and the blonde haired kid could be riku's soul still being pure. also the Enigmatic Man could have attacked Sora because he was working for The Organization and testing wheather the strongest is the body, soul, or the heart... of coarse the HEART
How was that for a questioned story
