Summary: Vanitas was beaten. Gone. Defeated. But even if he lost, he still has a goal he wants to accomplish. And he has the perfect host to help him with his new found goal...

Disclaimer: I do not own Naruto or Kingdom Hearts

Vanitas knew it. He had always known, deep inside, that this day would come. He tried to grow strong enough to stop it, he tried to be strong enough to make sure it would never happen. But there was no denying the fact it happened. There was no denying...

He had been beaten by Ventus.

The dark half of Ventus reached towards the X-Blade as it floated away from him, desperately trying to grab it and stay whole. He didn't want to fade away. He wanted to be complete. But he was too weak, and began to drift and disappear as the X-blade shattered.

'This is the end huh,' the bluenette thought. 'Beaten by the other...I can't let it end like this...I can't let myself fade away!' A fire of determination lit in his eyes. 'You can have your heart back Ventus! But I will not fade away! I still have my own goal to accomplish!' With the last of his power, Vanitas sent his will and soul out of Ventus, sending it away, where it would one day be sealed in a suitable host. 'Heh...even though you've beaten me Ventus...

I've still won...' With that thought, Vanitas' body disappeared as his heart merged with Ventus' once more. Ventus slowly closed his eyes as his heart became whole once more, though he felt something was...missing. But he didn't think about it. After all, with the X-blade shattered, he would soon fall into slumber...

Worlds away, a nine tailed demon fox was attacking the Ninja village of Konoha. It's tails lashed out, toppling mountains and sending tidal waves crashing on the shores. It let out a horrible roar as many Ninja attacked it, trying to hold it back.

"Hold it back, wait for Yondaime-sama!" One of them yelled to the others.

A dark spec of light hovered in the sky. 'Hmm...' a thought passed through the spec. 'It appears this beast is special...I can sense a dark energy coming from it...' the dark light noticed a man and a woman by a large group of rocks. The fox was bound by chains that had come out the woman's back, while the man had an odd figure behind him, but it made the spec seemingly shudder in fear.

The fox roared. "I WILL NOT BE SEALED AGAIN!" It yelled out and moved it's claw to stab something the dark light couldn't see. The man and woman jumped in the way, taking the blow and stopping the claw from hurting the unseen thing. The being behind the blonde man moved it's hand through his stomach, and grabbed hold of the fox, tearing away it's energy, making the demon shrink in size.

The spec would have grinned if it could as it saw what they were protecting. It was a child. 'Perfect...' it cackled. 'I think I just found my new host.' The spec moved and clung to the demon, the demon roaring in annoyance as it was sealed away inside of the blonde child. Soon after the sealing, the red haired woman and the blonde man fell to the earth, and knew no more, and the spec had one thought before it slept. 'Hehe. My time will soon come. This is my...birth by sleep...'

(12 years later)

A blonde haired boy sat in a dark forest, reading through a scroll. He had cerulean blue eyes, a slightly round face, and was tanned wonderfully. He had 3 whisker marks on each cheek and wore an orange jumpsuit. On his feet was a pair of oddly crafted sandals. Around his right leg were bandages, with a kunai holster slid onto it. On the back of his waist he had a pouch, filled with Shuriken and Kunai. The blonde groaned as he read through the scroll. "Shadow Clone Jutsu?!" He complained. "Everywhere I look there seems to be that damn cloning technique!"

He decided to skip over it, and saw something at the bottom of the scroll. A seal. "What's this?" He slowly pressed his hand on the seal, and a strong light began to shine. "Wh-what's going on?!" He began to feel pain shoot through his body. "AHHHHHHHH!" He screamed as his voice became darker and more demonic as the light engulfed his entire body...

He was falling through darkness, nothing around him as he fell. "What...is this..." he muttered. He looked down and saw a large circular platform. He turned in mid air and landed on it gently. "Where...am I?" He mumbled softly.

"Welcome," a voice said, startling the blonde. "I have been waiting a long time for you to arrive here."

"Who's there?!" the blonde yelled out.

"There will be time for introductions later," the voice promised as 3 platforms rose up, equal distances from the centre of the circular platform and spread out. The blonde looked at one and a sword appeared. "You must now choose your path..." he glanced at another, a shield appearing on that one. "If you give it form..." he rolled his eyes, looking at the final platform as a staff appeared. "It will give you strength. Select your path." The Shinobi groaned and walked over to the sword. The voice spoke. "The path of the warrior...unstoppable power...a sword of terrible destruction..." The blonde frowned. He walked to the shield, the voice speaking once more. "The path of the guardian...the power to protect...a shield that repels all..." He frowned once more, walking to the staff. "The path of the mage...power to attack with spells...a staff of wonder and ruin..."

The blonde looked at his three choices, then shook his head. "None of these are for me...I don't really have anything I want to protect, nor do I particularly want to cause destruction..."

The voice spoke once more. "Then perhaps this will be better for you." A fourth platform appeared in the centre, as a black cloak appeared on it. The blue eyed boy raised an eyebrow as he walked to it. "The path of the seeker..." the voice spoke. "The desire to search for power...to summon creatures to serve and protect you..." the blonde stared at the cloak before grabbing it and putting it on. The air shifted, and the blonde could swear the voice would be smirking if it had a form. "A good decision...you must now select what you want to give up in exchange for this path..." he immediately walked over to the staff. He grabbed it. "Will you give up this power?" He looked at it before crushing the staff in his hands. A bright light engulfed the area suddenly. When it cleared, the platforms were gone, the blue eyed boy looked around, seeing 3 familiar people. The aged Hokage, his crush- Sakura Haruno- and Iruka Umino, all standing around him. "Now, tell me more about yourself."

The blonde walked to the Hokage. "What is most important to you?" He asked.

"My precious people," he responded without hesitation. He then walked to Sakura.

"What do you fear most?" Sakura asked him.

The blonde was silent before he answered. "Being alone..."

"Is being alone really so bad?" She asked. He ignored her and walked over to the last person, Iruka.

"What do you want out of life?" The scarred Chunin asked.

"To show everyone that I'm not worthless," he told him.

The voice spoke again. "Your precious people are important to you...you fear being alone...you want to show everyone your not worthless..." A bright light began to glow. "Your journey begins at the dead of night. You shall grow strong, and find people to protect, but you shall also be the strongest." There was another flash of light, and he now stood in front of a door, with two odd looking weapons on either side of it.

The one on the right was beautiful. The blade of the weapon was pure silver, slicking up and 3 sharp points stuck of it at the top, with circular balls on the tips, shaped like a crown. Traces of gold were also on the blade. As it grafted down, the hilt of the blade was wide and golden, cutting off in two directions, then going down and then re-joining at the bottom. Down the middle of the hilt was the handle of the weapon, with a red grip. Trailing down off the weapon was a silver key chain, with 3 circles at the end, one large one and then two on the top right and top left of the circle respectively. (Kingdom Key...)

The weapon to the left seemed to look much more...sinister. It didn't look evil, but it just had an aura that emitted hatred and despair. The blade of the weapon was black, reaching further than the Kingdom Key. A oddly grooved edge jutted out just by the top, a small spike just above that, and the top of the weapon was sharp and pointed, made for killing. The hilt of the weapon ran around the handle, and was blood red. Between the hilt, running down it's center, was the handle. It was pitch black, like the blade. (Dark Heart...)

"You must now select your path. Will you choose light?" A spotlight shone on the Kingdom Key. "Or darkness?" The spotlight shone on Dark Heart. "One of these Keyblades shall open the door before you. Which shall you pick?"

The blonde looked between the two. He could feel the two Keyblades trying to repel the other, trying to stay completely separated. The blonde looked between the two. "Again...I cannot pick between the two...I am not a person to walk in the light...nor am I one who bathes in the darkness..."

The voice grunted. "You wish for a third choice? Then you shall have it." A third weapon appeared between the two Keyblades. The blonde instantly knew it was what he wanted.

This Keyblade was beautifully crafted, in the mind of the blonde. The blade of the weapon was thick, like the other two, and was a deep crimson, with traces of black swirling up it, and reached far out. What appeared to be half a Shuriken jagged out just by the top, with thick circles around the tips of the blades, like Kingdom Key. The top of the weapon was sharpened, like Dark heart. The hilt of the Keyblade, like the other Keyblades, went around the handle, thin like Dark Heart, and was pitch black. Images of an orange nine tailed fox was carved into the hilt of it. The handle ran down the center, with a dark orange grip. An orange key chain trailed down at the bottom of the blade, a fox dangling by it. (Forsaken By Light...)

"This Keyblade is made by combining the light and darkness, though more darkness than light," the voice told him. "If you accept this path, you shall control both the light and the darkness, but it also means you will be an enemy of the two forces. Will you accept this path?"

The cerulean eyed blonde reached towards it and picked it up. He gave it a few practice swings, and smirked. The Keyblade felt absolutely perfect in his hand. He looked towards the door, and noticed a mixture of light and dark energy was emitting from the top of his new weapon. With a grunt, he thrust the weapon into the Keyhole. It fit perfectly. He twisted, and there was a click, signifying the door opened. He pulled his Keyblade out and stood back as the door swung open. He walked in, and ended up on top of the Hokage Monument. "How did...?"

"A gift," the voice said. "You shall need more than just that key to survive in other worlds." A small orb of black energy appeared in front of the blonde. It shot inside him, and he felt his clothes shift. He looked down and his eyes widened. He now wore a pair of black jeans, along with dark orange sneakers. His top was black, with a crimson swirl on the right sleeve and the words 'fade to darkness' on the front in white. He wore his black cloak over it all, opened, with the hood down. Attached to his jeans was a black keychain, a miniature dark blue book attached to it. In his hand was FBL. He felt his head. He no longer wore his goggles, so his hair was wild and un-tame. On his shoulder was an odd device that had a large, circular button. The device was black, and the trims and edges were orange and gold. He also noticed he was a bit taller than before.

"Clothes fitting for a seeker," the voice spoke. "You have attained the Spellbinder of Knowledge. With this, whenever you arrive at another world, you shall instantly gain all information on the world you have arrived in. You shall also gain knowledge of enemies you shall encounter." The blonde raised an eyebrow.

"Why are you giving me this power?" He asked.

"All the power you have, you are getting on your own." "The voice told him. "I am giving you no power. These powers are yours that were once dormant, now awake. You have been sleeping for a long time. This is your station of awakening."

Another flash of light, and the blonde was standing on a new platform. "Now, it is time you learn how to use that weapon." His eyes widened as blobs of darkness appeared on the ground, and out of them rose small creatures. The skin was pitch black, and the eyes glowed yellow. The beasts were small. They had a large head with 2 antenna poking out the top. A small body, along with small arms and claws, and even smaller legs and sharp feet. It moved around, almost nervously. (Heartless: Shadow...)

The blonde simply looked at them, and all the Shadows leapt at him. He rolled out the way, looking at them as knowledge entered his mind. "Shadows..." he murmured. "Weakest Heartless known to date...born of very week hearts...under the category of 'Pure Blood' as they do not release a heart upon destruction by a Keyblade...they attack in groups, jumping at an opponent and lashing out with their claws..." He blinked and noticed the Spellbinder of Knowledge really did give him information about enemies. He readied Forsaken By Light, and charged at them. A Shadow leapt, but he rolls under it, slashing it in half with his keyblade. The shadow dissolved into darkness.

The blonde gave a fanged grin. "Well? Come on!" He charged at the remaining Shadows, slashing through them without mercy. One tried to jump away, but he grabbed it's leg and pulled it as he thrusted his sword forward, stabbing into it's gut and making it dissolve into darkness. One tried to jump him from behind. He swung his keyblade without even looking and cut it in half. He looked around. "2 left..." He mumbled. He focused his chakra into his Keyblade and it immediately lit on fire. The blonde grinned. "Nice..." He ran to one shadow, cutting it down the middle, and the final one made one last, desperate attempt. It never stood a chance. He caught it's claw and cut it's arm off. It fell into shadows as it retreated.

"Well done..." The voice spoke. "An experienced Keyblade wielder could do no better than you have just now." The blue eyed boy blinked, and then realized he had just been given a compliment. "But a warning to you, young Keyblade wielder," it spoke, and the blonde was beginning to get annoyed. He wanted to find this voice and kill it! Suddenly, the blonde felt something leave him. He looked behind him and his eyes widened. He saw a small blue creature, with small, slit red eyes. It seemed to want to dash around, and looked at him as if awaiting his orders. (Unversed: Flood...) "You control more than just the powers of a normal Keyblade wielder. You have a special power to manifest your negativity in the forms of these monsters. They are called..."

"Unversed..." The blonde finished, his Spellbinder giving him the knowledge. "Born from my negativity...Unversed are perfect training partners as you can fight them, and upon defeat they will flow back into the owner as the negativity they once were...this specific Unversed is a Flood...the weakest of the Unversed, however what it lacks for in strength it makes up for in speed. It can move fast...and can become a blob of darkness in the ground to travel behind the enemy and strike them..."

"That is correct," the voice confirmed. "But you must remember, young Keyblade wielder. You still need to train, and become stronger. You walk the paths of both light AND darkness. You control both powers. Because you control darkness, you are able to make dark portals that can take you to any location that you have once been to. Because you hold the powers of light, you can make a gateway of light and travel to other worlds with the aid of your Keyblade."

"That's all well and good," the blonde muttered. "Can I go now?"

The voice chuckled. "Very well. It is time for you to return to your reality. And remember, you are both a seeker of darkness, and also a warrior of light. Now go forth, your journey begins now, Naruto Uzumaki!"

The blonde yelled out as everything went white, and he was pushed back into reality...

Naruto's eyes snapped open, and he noticed he was still in the forest, holding the forbidden scroll. "Was that...a dream?" He looked down at his clothes. They were the same as when he was 'dreaming'. "No..." he mumbled. "That was no dream." He held out his hand, and his Keyblade appeared in a flash of light and darkness. He looked at it. "...Forsaken By Light...fitting..." He heard a sound, and turned around, holding his Keyblade at the ready. He blinked upon seeing the scar across the face of a familiar Chunin. "Iruka-sensei?"

"NAURTO!" He yelled, furious, but also a little surprised at the weapon in Naruto's hand. "WHY DID YOU TAKE THE FORBIDDEN SCROLL?!"

Naruto blinked and stepped back, keeping a tight hold on the scroll. "So...I've been tricked it seems..." Naruto pointed his Keyblade behind him. A beam of light shot out a few feet behind him, and an oval shaped portal, emitting light and crackling with energy, appeared behind him. "But I am done with this world...for now..."

Iruka blinked. "Naruto...?"

Naruto pointed FBL at a tree. "Come out Mizuki-teme," He growled. "Let me end you before I leave this world."

The silver haired Chunin appeared. "Give the scroll Naruto," he ordered evilly.

"Mizuki?!" Iruka yelled.

"Shut up," Naruto growled in anger. Dark mist rolled off him and took the form of a new creature. It was large and blue, with the colour grey running over its stomach and the lower half of its back. In them middle was a black symbol: The Symbol of the Unversed. It had wide, completely red eyes, scalera and all. Its arms were short, with the elbows spiking up and it seemed to wear black gloves. It's legs were small, but it seemed to be able to move easily enough. (Unversed: Bruiser...)

"What is that?" Mizuki demanded of the blonde Uzumaki.

"This, my dear Mizuki, is the instrument of your death," Naruto grinned evilly. He addressed his Unversed. "Kill him."

The Unversed went into movement, it began charging at Mizuki slowly. Mizuki took a large shuriken off his back and threw it at the creature. It sunk into it's stomach, causing a minor wound, but the Shuriken simply popped out of its stomach as the wound healed. The Bruiser punched the tree Mizuki was on and it fell, landing on top of the silver Chunin once he hit the ground. "AHH!" He yelled in main. The bruiser jumped up and landed on Mizuki, crushing him and ending the life of the silver haired Chunin.

Iruka looked at Naruto in horror. "N-Naruto?"

The Unversed dissolved in the dark mist that rolled back into Naruto. The Uzumaki backed towards the portal. "Tell them Iruka. Tell them of what they made me become," he told the Chunin, as he continued backing away.

"Wait, Naruto!" The Chunin tried to walk to him, but Naruto held his Keyblade towards him.

"Don't touch me!" He yelled, but controlled his anger to prevent an Unversed coming into being. "Keep away Iruka," he warned as he stepped into the portal. "I am a seeker...and what I want...is power...to get revenge on what you people have done to me!" With that, the portal closes, Naruto and the forbidden scroll inside of it.

Iruka drops to his knees and, for the first time since his parents death, cried at the loss of a boy he thought of as his own son...

Naruto was hovering through a deep blue space, he saw a single world next to his own. The world seemed to be a town, with a large clock tower. "Where am I?" The blonde muttered, and his Spellbinder of Knowledge gave him the information. "Oh I see...this is the space between worlds, the space Keyblade wielders, heartless and other beings cross when they head to other worlds..." He looked at the forbidden scroll, then used a seal he gained from the Spellbinder to seal the scroll into his skin. "I can use you later..." he muttered.

He stared at the world then gripped his Keyblade and it transformed into a black hover bike with the image of an orange fox on the front, with blazing crimson flames on the side. "May as well check out this new world..." He revved the bike and it shot towards the new world.

Deep within Naruto, a voice chuckled darkly. 'Yes Naruto...grow strong...so that I may reach my goal...'

(?)

In the world with the clock tower, a man dressed in the same cloak as Naruto stood on the clock tower, staring out into the world with the setting sun. He saw a light descending on the world. "Hm? That way of transportation..." the man murmured. "Only 3 Keyblade wielders I know travelled through that method...who is it...has Aqua escaped the realm of darkness? Has Ven awoken from his slumber? Or has Terra somehow regained his body? In any case..." the man lowered his hood, revealing a young, dark skinned man with silver spiky hair and golden eyes. "I have yet another pawn to use..."

(?)

A young blue haired woman sat by a lake with a man in a black cloak. "Who was he?" She spoke, curiously.

"His name is...Sora..." The man spoke, and a gateway of light opened up in front of them.

The bluenette was on her feet immediately, looking at the gateway in shock. "Wh-what?"

The man stood. "It appears fate has given us a second chance to fix the problems that I have made..."

The blue eyed woman looked to the man, then back to the gate. "Who made this gate...?" She muttered. The cloaked man did not hesitate, as he walked into the gateway and vanished. The bluenette was uncertain, but walked into the gate. She felt the familiar presence as it began to close with her in it. She spoke one name, her voice full of shock...and hope. "V-Ven...?"

To be continued...
