Disclaimer: I do not own Kingdom Hearts, nor Naruto. If I do, Sora will be less of an asshole in KH2, and the Jinchuuriki in Naruto will have a back story at least. Sigh.

AN: Follows KH2 storyline up to Xemnas defeat, but will not play a key role in this story. (Basically KH knowledge is hardly needed, just read up on Organization XIII) Sketches mainly along Naruto timeline, with a few amendments to timeline of events, one Nobody really screws up the world.

"Demyx" Flashback Jutsu, Technique, Demon/Greater being speech

Nobodies. As powerful as the heart is, take it away, and they become stronger. Creatures which should have never existed, created out of the strong will of their former selves. Then there is Organization XII. Defying the very nature of science, they not only exist normally, but act as an improvement to their previous selves. Being rare nobodies with extraordinary will, they take a humanoid form, as well as being blessed with a specific element.

Then there's Demyx. The joker of the organization. Blessed with control over water, but abusing this to pull off pranks with Axel and Roxas, and skips work. Most believed that he was mimicking his happy childhood, and reenacting it based from his memories, after all, nobodies can't feel emotions right?

Little did they know that his childhood was a worse hell than living without emotions. The playful facade, childish attitude, cheery grin, all of it was none other than a method of escapism from the torment which he endured in both lives, his previous, and his current, if he even considered this as a life.

"Hey, what's your name? Surely you must have remembered? Ya see, it's like, an organization policy to take your name and scramble it with an X, making a new you. Got it memorized? "

"Just... Call me Demyx..."

Right now, Demyx was in a bind. Under orders, he was to combat against Sora, to draw back Roxas. With Axel rogue, the Organization believed Demyx's proximity to Roxas as a second friend will help Roxas fall back into the Organization's palms...

"Come on Roxas! Didn't ya forget your friends?" Demyx questioned Sora, having his goofy grin. This shouldn't take long, after all, escape will always be a plan B.

It only started when Sora remarked that nobodies don't even have hearts, and should not even exist. The contempt within his eyes reflected well off Demyx.

'Those eyes... None other than those sick fucks back in my previous life. Judging me, for what is beyond control, never for who I really am... ' The look on Demyx's face darkened considerably

Demyx may appear incompetent and childish, but underneath this face, he can be as heartless a killer as anyone, mainly the reason of staying in the main castles while the useless members as well as traitors were posted to Castle Oblivion. Immediately, after he heard those words, he spoke, voice changing to a cold, harsh tone. "You really shouldn't judge anyone by appearance".

Almost immediately, he whipped out his sitar, and started strumming a tune. "Well hero boy, let's play a game! Dance water dance!" Immediately, multiple clones of Demyx materialized from the moisture in the air. "Kill my clones before the song stops! Else, it will be your dance... to your death."

Almost instantaneously, Sora rushed up to the clones, decimating them almost instantly. Both parties were competing for time, neither having a clear lead of the other. Falling into the last phase of his masterpiece, Demyx decided to take one glance at Sora... And hesitated unconsciously hesitated. The look of determination, never to abandon his friends. To fight against the impossible. To take the hits for the one you love. Just like the sacrifice of his previous life... The hesitation proved fatal, Sora destroying the final water clone barely a second before Demyx was completed his song. Exhausted from his technique, coupled with his hesitation, Demyx did not retaliate, letting the keyblade impale his chest. As he faded into darkness, one thought lingered in his mind.

'Who would've thought that senseless determination will save your friends? Right? Sauske...'

It was fated that day. As the two great powers clash, a spiraling torrent of energy against a blade of lightning, one hesitated. That hesitation cost him his life. His name was Uzumaki Naruto.

Demyx woke up in a white room, reminiscent of his days in the castle. 'So I survived? That or the afterlife is not much different than I thought... Maybe a bit too white for my liking, but, that means I'm in heaven right?' Demyx blinked in surprise, attempting to comprehend the large information intake of his 'death'.

"Am I dead?" The Nobody sat up, quickly scanning the room to see only a clean hue of white light. Although still lacking a heart, Demyx displayed a rare show of true emotion as he looked at the mirrors depicting his life.. As well as his previous one.

Uzumaki Naruto

"Oh, you woke." A man looking no older than 30 trudged into the room. Hesitantly, Demyx questioned him "Who are you?"

"Yeah, about that, I'm pretty much what one calls God, Shinigami King, Kami, Zeus, and Jenovah, you know? Oh yeah! Note to self, kick that Seph's ass for having his fantasies of me as a woman. Not cool..." The man spoke nonchalantly. As Demyx rose an eyebrow, he continued. "You see, the reason why you are here is cause, you aren't supposed to die just yet." Ignoring the huge exclamation of surprise, the man further explained. "Technically, I was supposed to heal your wounds and prevent your death, but some idiot named Aizen just had to try to take my place. Result? 6 months of paper-fucking-work!"

At this moment, Demyx was starting to have second doubts at the man who claimed to be the ruler of all universes.

"Yes, I know. Well, this is a side effect from being what you call the ultimate ruler. Way too many worlds to manage. But anyway, I'm pretty much freed up now, and would like to make amends." The man's face darkened. "Your unintentional death has thrown off the chain of events originally meant to happen. As such, as a form of apology, I will make this offer, I will resurrect you back in your time. But due to past events, a 2 and a half year time gap is needed to prevent a time paradox. However, do note, after your resurrection, you will retain the powers gained by the nobodies, and slowly redevelop your chakra coils. As a result of your death, the Kyuubi is now loose. Not only will you have to fight the demon, you lack the insane power gained from the fox. But still, I believe your enhanced regeneration and superhuman strength as a Nobody compensates from that. Lastly, who do you want to be resurrected as? Demyx? Or Naruto."

Demyx pondered for a while, before giving his answer. "I will return as Demyx, for the time being. Well, after all, I lost my heart in this world, and I hope to remain as I am, before returning as Uzumaki Naruto. For now, just, let me keep my lack of a heart. I do not deserve it."

The man smirked "Very well, have fun!" He yelled as he kicked an unsuspecting Demyx through a rift of dimensions.

"Ow, that hurt..." Demyx groaned as he got up. No doubt this looked like his old world, as dozens of recon missions he practiced during his organization days made his aware of the various properties of different worlds, but there was something off. Why is the ground grey? What's up with the well proportioned spikes? And whats with the 3 tails floating in the sky...

'Oh wait. Did I just land on the Sanbi?'

'Shit.'

AN: Future author notes will be left at the end of the story. This is my first story, please R&R. Constructive criticism is appreciated, flames are not.

Regarding Demyx: I plan to have his same, cheery self, constantly overlapping with Naruto, but more often, his serious side will appear, being a result of constant fighting with S-Ranked criminals (hint hint). The main reason for the manifestation of his serious alter ego is due to his days in Organization XIII, the constant killing of heartless is bound to make you more experienced and battle ready!

Chapter 1 will be my only KH-centric chapter, the rest will follow the Naruto timeline without inference of other worlds.
