Hello everyone. Welcome to my latest (and hopefully one of my greatest) fanfiction, Keyblade War. I got the idea for this when I finally finished Kingdom Hearts II (I beat it like a month ago). When I was done, I was in a Kingdom Hearts craze. At the same time, Naruto: Shippuden was released, so I started to watch that as well. I started to notice that some of the characters from Naruto act like Kingdom Hearts characters. So, after a bit of brainstorming, Keyblade War was born. It's a retelling of Naruto using Kingdom Hearts. Now, the story will be similar like Naruto, but I make some changes and will write everything. I'll try to make it so it's not exactly word for word and many things I thought of, but for the basic part, it's Naruto. Also, I don't plan on using any Disney characters for this. They just don't seem right. The only one I'm using is Mickey Mouse, maybe Donald and Goofy and that's it. Unless I really need another Disney character. So, read and enjoy.

Disclaimer: I do not own Naruto for he is owned by Masashi Kishimoto-san. I also don't own Kingdom Hearts for that is owned by Square Enix and Disney. Man, I don't own anything except for the box I live in while writing this... wait, never mind... hobo stole it. T.T

Prologue: The Nine-Tail Heartless.

Quiet. It was quiet everywhere, as every man, woman and child was transfixed into one location- the center of their city, Radiant Garden. In the center stood a giant beast that took the form of a giant black fox with glowing yellow eyes and a black and red heart symbol on his forehead. His legs were as wide as tree trunks and his teeth were sharper than any sword ever forged. The creature also had nine long tails that swayed wildly. This creature was a heartless. But, he wasn't just any heartless; he was a Shinzuma, the heartless of a God. It is said that all living creatures have hearts, and all hearts have darkness in them. And everyone is vulnerable to that darkness. Not even a God has the will to fight against it. And, when a God does lose its way to the darkness, a Shinzuma is born. This Shinzuma happened to be the heartless of Kyuubi, the God of Tricksters. Kyuubi was a popular God in Radiant Garden, especially with the kids. So, when his heartless appeared from one of the corridors of darkness and started to attack the village, confusion and sadness had befallen the citizens. But nothing could prepare them for what was to happen next...

Silence. For a minute or two, then... "Now... go!" cried out a strange figure. He was covered in a white robe and cape. The only feature one could see was his brown, spiky hair. He was a man of power, the most respected man in all of Radiant Garden. His name has been lost since the day of his greatest triumph. Only a few individuals know his true name. To the rest, he is known as Yonkingu. He is the king of Radiant Garden, a great ruler who is loved by all. But, today... he will show everyone how much he loves his kingdom. Even if it costs him his life!

After Yonkingu yelled his command, troops of people with giant swords in the shape of keys, known as Keyblades, ran toward Kyuubi. "Die, you beast!" cried one Keyblader, but he was quickly disposed of with a swipe of the Shinzuma's tail. Unfortunately for the Keybladers, the result caused the man's heart to be engulfed in darkness and turned him into a heartless. So, the Keybladers not only had to worry about the Shinzuma Kyuubi, but they must also deal with their fallen allies who became heartless.

After a couple of hours of fighting, things looked grim for the Keybladers of Radiant Garden. Families were torn apart when fathers and mothers' hearts were stolen; friends were stuck down by other friends when they became heartless. All the while, Kyuubi didn't even have a scratch. The Keybladers were getting restless and moral was low. Many of them gave up and allowed Kyuubi to take their hearts away. Some of the nobler one's committed suicide to prevent their hearts from becoming a problem to their fellow buddies.

At the top of the tallest building in Radiant Garden, Yonkingu was standing. In his hand was a Keyblade with a strange design. In the heart of it, the Keyblade was basically a sword. One side of the blade was silver and the other was light blue. The middle of the blade was golden, as well as the hilt. The handle was a dark black. The crest of the sword was in the shape of a heart and a weird, net-like design surrounded the blade and gave it its key appearance. It was the Ultima Keyblade.

Yonkingu looked at his village. "My people... are suffering. Because... of this... dark remains of a heart." Yonkingu took his Keyblade and said, "I knew there would be a day when I must use this." Behind him, a figure appeared. He was fairly small, probably up to Yonkingu's waist. He was wearing a black cloak with a hood that covered his face. Although, one could see two big round ears under his hood. He was holding a golden Keyblade. He walked toward the King and said, "Are you sure about this?"

"Yes, more sure than anything in my entire life."

"Is there no other way?"

"Look down, every second a new heart is stolen by this beast. Families are being torn apart. This thing" he said looking at his Keyblade, "...can save them."

"Did you find a host?"

"Yes."

"And who would that be?"

Yonkingu looked down at the building near by. The cloaked figure knew who he spoke of.

"You can't mean 'him!' He is just a baby!"

"It is easier when they are young, also... who better than him?"

"What about Namine? She is already empty. Why not her?"

"She isn't... pure enough to hold him. She may have none, but she will be corrupted."

"Very well, it's your keyblade, and your heart." the cloaked figure started to walk away, when Yonkingu said,

"One more thing... take care of him for me. Make sure the citizens see him... as a hero."

"...very well." The cloaked figure left.

"Thank you... sensei."

Yonkingu looked straight into the Shinzuma's eyes, tears and hatred flowed out of his own. With Ultima ready in hand, Yonkingu said a couple of words and rushed toward the beast. The giant Heartless saw the King run toward him and with a flick of his tail attacked Yonkingu. But Yonkingu isn't known as the Golden Flash for nothing. With a sudden flicker, the King suddenly disappeared. Kyuubi looked everywhere, searching for his prey. In his mind, nothing would satisfy him better than to turn the leader of these pathetic humans into a heartless. A heartless he would control. Too bad the demon's desire will only be a dream. Just as fast as he left, Yonkingu appeared, right in front of his face.

"Hello... monster." said Yonkingu.

Human... you dare challenge me... how pathetic. But, I promise you, by the end of this day, I will take your heart!

"Hmm... you're right. I will lose my heart today... but not to you! But from the power of this Keyblade!"

What? What do you mean!?

"Ultima... you've served me well these past years. How I wish we could spend more time together. But, alas, fate is cruel and I have been destined to cut our time together short. So... I beg of you, activate you final strength... and with the power of my heart... seal this heartless away."

A bright light surrounded Ultima and Yonkingu. The light was so strong that it illuminated all of Radiant Garden. Every being, human and heartless stopped and looked into the sky. The giant ball of light caught everyone's eyes as they all stood there mouth a gapped, wondering what was to happen next. Nearby was a young boy with a short leather jacket with a red wing design on the back. He had black pants and around his neck was a silver necklace with a strange medallion on it. In his hand was a sword that looked like a gun. He looked up into the sky and said, "So... he's gonna do it." The boy put his sword away and walked off. Back at the battle scene, the light that surrounded Yonkingu grew brighter and brighter. Soon, his body had disappeared and in the center of the light was a heart. Yonkingu's heart. Ultima then pointed toward Kyuubi and before the beast could react, a stream of light hit the Shinzuma on his heart crest.

Wha... what's happening!? I feel... so weak.

This is the power... of the light in a heart..., said the voice of Yonkingu.

Light... in the heart?

But before Kyuubi could say anything else, he was completely engulfed in light. The light then started to reverse and entered the Ultima Keyblade. Within a few moments, the evil fox's heartless, as well as all the other heartless, had disappeared and all that was left was a glowing keyblade and the heart of their late king. Then, before anyone could move or say, "Oh shit!" the Ultima keyblade pointed at Yonkingu's heart and stabbed into it. The keyblade disappeared into it and the heart became a ball of light. The ball of light slowly entered a near by hut and entered the house. In the middle of the house was a newborn baby, with spiky brown hair. He was crying loudly but no one came to help him. The ball of light approached the baby. The young infant looked at it playfully as the small light swirled around it. A small tear fell from the light as it sunk into the young child's body. The baby cried as a pattern was forming into his stomach. It took the form of a heart... a reminder of what has happened. This marks the beginning of a journey. A journey of self learning, a journey that will affect the young child and those around him. For he is the key to the future of the worlds. He is... Sora.

And we're done. So, what do you think? I rewrote this chapter like 5 times to get it right. I was originally gonna just go onto the first episode, but what the heck, I thought you guys might like to see a more extended version of the sealing. So, Yonkingu (who is obviously the Fourth) sealed Kyuubi's Heartless in young Sora. Now, the next chapter takes place 12 years from now, where the real story begins. So, I'll try to make the next chapter soon. But, I have many obstacles in my way. I have to write a script for a movie and talk show at school, so I will be very busy. Also, I still need to figure out who plays who. I assume you know who that cloak guy was. But can you tell me who you think he was portraying? Same thing for the boy with the sword. Tell me and I'll... congratulate you, I guess. It's not that hard, you just need to think. Well, until next time, remember, RxR. Peace out.
