Chapter 1: The End of this World

In a non-descript area, which was formerly a land filled with trees and vegetation but was reduced to an uneven bare scar on the earth, two men with their own ambitions for the world gazed in silence at the sight before them. They stood on top of a being which had a grotesquely bloated, round body and seemed to crawl on its belly, while branch-like spiky protrusions grew out of its back at a straight angle. It had a singular unique eye, taking up most of its head, four concentric circles with six tomoe in the two circles closest to the pupil. It also had a wide, cavernous mouth with multiple rows of sharp, pointed teeth, as well as a spiked chin. It was possibly the largest being in the world, the source of all chakra, but is also the progenitor of everything that exists in this world…The Ame no Hitotsu no Kami, the One-Eyed God or the Juubi.

The man on the left peered over the land, his mismatched eyes narrowing in barely concealed frustration. He wore a pair of black pants and gloves, with a white, presumed form-fitting shirt underneath. Over this he wore a purple, high-collared, long sleeve mantle that split down the lower half and had the Uchiha crest on the back, though the left sleeve had been all but torn off. Around his waist he wore a simple, light-purple obi and a belt. His left eye had a ripple-like pattern which spread over the eyeballs, with light purple irides and sclerae. His right eye, on the other hand, was a stunning red with a black design reminiscent of a pin-wheel in the center. This man was Uchiha Obito, the man responsible for the Fourth Great Shinobi War.

The second man merely crossed his arms, his bored look remaining on his visage. He was a tall, fair-skinned man with spiky, black hair that had a slight, blue tint to it. By adulthood, his hair had grown to waist-length with shoulder-length bangs framing the sides of his face, covering his right eye entirely. Although still relatively young, more prominent creases had developed under each of his eyes. In most cases, his attire took the form of the standard shinobi dress of a previous era, consisting of bright red traditional armor — similar to that of samurai — worn over a simple black suit. This armor was constructed from numerous metal plates, formed into multiple protective guards along his body, in particular: chest, waist, shoulders and thighs. Unusually, his chest plate left his back entirely exposed, presumably so as to better display his clan's crest. This clothing was accompanied by boots and gloves. Strapped to his back, he carried a crimson gunbai with black trimmings and black tomoe, connected to a black chain that runs up his right sleeve. His Rinnegan eyes surveyed the scene before him with amusement. His name was…Uchiha Madara.

Standing several meters away from them were the entire Allied Shinobi Forces, minus the Five Kage of course. Standing in the center of the group of distinguished shinobi were three battle-worn Leaf Shinobi, all who were gathering their second wind for the inevitable clash against the Uchihas. The most notable one of them all stood proudly with a determined expression on his face, his fingers in a cross sign while his eyes bore into Madara's disinterested ones. He had ocean blue eyes and blond, spiky hair. He wore an orange and black jumpsuit with black sandals as well as a black headband. He also had three whisker marks on his face which greatly resembled that of a cat or fox. He switched his gaze to Obito and called out. "You think we're still a disorganized group?! We are…the Shinobi Alliance! Keep it in mind!"

Obito said nothing, choosing to just stare at them with impassiveness. After a few moments of staring at them, he finally spoke his words. "It matters not whether you are a thousand or a hundred thousand…none of you can hope to compare with the power of the Juubi. The Eye of the Moon Plan will be fulfilled…one way or another."

The Juubi roared in agreement, forcing all the Allied Shinobi to the ground while the earth trembled beneath at the sounds of its creator. Naruto grit his teeth as he quickly staggered to his feet, wracking his brain on what they could use to defeat the two Uchihas. 'Kurama, how much longer until you can come back out?' He questioned, absently wiping sweat from his forehead.

Inside the seal, the Kyuubi no Kurama's closed eyes gained a minor tick mark as he sat in a meditative posture. "I won't be able to merge ourselves together for at least another five minutes or so. Just try and hang on until I can rejoin the fight!" He ordered.

'Gotcha.' Concentrating on his chakra once more, Naruto wearily summoned two Kage Bunshins beside him. He turned to the Shinobi behind him, the beginnings of an idea stirring in his mind. "Ino," She snapped to attention immediately, ready to hear his plan. "D'you think you and Hinata can manage to control them again? I need just two seconds to pull this off." The seriousness in his voice reflected how much he needed this part of his plan to work.

"Hai, though I doubt that it'll be as easy as it was before."

Nodding his head, he shifted to the other Shinobi. "Anyone with an A-Rank Katon jutsu up their sleeves?" A chorus of "Hai!" answered his question. "Alright, here's what we're gonna try!"

With Madara and Obito, the former was ever so subtly forming the hand-seals he had mastered over his long life to obtain more power. The Ninpo: Douka no Jutsu (Ninja Release: Assimilation Jutsu) was a jutsu he had initially started creating with his brother Izuna. The concept of the jutsu was for the user to selectively withdraw certain desirable traits from the enemy shinobi and absorb them into the user's body. It had originally been their plan to find a way to restore Izuna's eyes…but he had perished on the battlefield the next day. Ever since his defeat at the hands of Senju Hashirama in the Valley of the End, he had been forced to rely much more than he pleased on the Douka no Jutsu in order to rejuvenate his life-force when he found his body reaching its limit.

However, this time, his targets were the last two Jinchuuriki; Naruto and Killer Bee. Despite the fact that the Juubi had been successfully revived, Madara wanted more. He wasn't content with becoming the jinchuuriki of an incomplete Bijuu…he wanted to be the shinobi who would finally surpass the Sage of Six Paths himself! With the Douka no Jutsu, he could possibly assimilate both of them into the Juubi and hopefully trigger a reaction in the One-Eyed God to become complete. 'I must hurry and seal the last pieces into the Juubi before Obito starts getting impatient once more…why couldn't he just stick to the plan we had and gather all the Bijuu before he resurrected the Juubi?' Stopping on the last seal, Madara was about to shout his jutsu for the Allied Forces to hear but was stopped by the sudden bombardment of jutsu.

Dragons of flame, boulders of varying sizes, water bullets from a particular cluster, wind blades and tornadoes flying around in different directions, and even the occasional streak of lightning could be seen hurtling towards the two of them. Using his link to the Bijuu, Madara concentrated as the Juubi opened its shark-like mouth. Negative white energy and positive black energy formed at incredible speeds, already being swallowed by the beast as it solidified into a condensed ball of chakra. Madara smirked as he readied the Tailed Beast Skill. "Bijuu Reizā. (Tailed Beast Laser)"

The attack was fired at an intensity that took the Shinobi Forces completely by surprise, judging their shocked faces and rapid paling. The dense mass of chakra had easily swallowed their attacks, cutting a deep trench through the earth as it headed towards them. "Katon/Futon: Gōryūka no Jutsu/ Chou Oodama Bijuu Rasenshuriken!" Came the cry of Naruto and a majority of the Shinobi Force. It was at that moment, when the devastating abruptly disappeared into strands of chakra, that a massive dragon head erupted from the dust cloud that had been kicked up by the Bijuu Reizā, a large orb of black chakra surrounded by four large points resembling a fuma shuriken.

Obito sent a glare towards the elder Uchiha. "Enough showing off, let's get the project started already." Facing the approaching attack, Obito attempted to send it into another dimension using his Kamui…but, to his disbelief, the warping barrier he expected to see was not forming at all. Stealing a glance towards Kakashi, he noted with slight annoyance that he was indeed interfering with his activation of Kamui. 'How is he gaining knowledge on the usage of Kamui so quickly? Before, he could only teleport objects into a separate dimension, but now he's even capable of stopping Kamui from taking place…'

Madara paid no mind to the incoming fire dragon, slowly going through the hand-seals he needed for his assimilation jutsu. However, due to the arrogant nature of the Uchiha leader, he failed to notice that he had made an error in the order of the hand-seals. As the roaring dragon finally crashed into them, Madara uttered his jutsu. "Ninpo: Douka no Jutsu!"

As soon as he felt his body start decomposing, Madara knew something was wrong. The jutsu was supposed to 'pull' the chakra of his targets towards him, not the other way round. Also, he could see that he wasn't the only one being affected by the jutsu; Obito had sunk to his knees, a silent scream etched on his face. Beneath him, Madara could feel the Juubi writhing in discomfort as chakra strings emerged from its eye and started latching onto the various shinobi that were strewn across the land. Madara felt a sliver of fear worm its way into his heart as two strings attached themselves to him and Obito.

Then the pain slammed into them. Madara thought he had known what pain really felt like, having endured a beating at the hands of Hashirama himself, yet what he was feeling right now surpassed even that experience. He could literally feel his very being fade portion by portion, flowing straight into the mindlessly shrieking Juubi. Despite the burning pain he felt, Madara lifted his head to survey the land.

He wasn't the only one affected by his unintentional jutsu…each and every one of the Allied Shinobi Forces was either dead or in the process of dying. The jutsu had been adjusted to function like the Human Path of the Rinnegan, meaning the enemy shinobi would die after the jutsu was complete…but he had a body constructed by the Edo Tensei, so what would happen? WHY was this even happening? He was supposed to enslave the Shinobi world and rule it, with Obito being stuck in his own 'ideal' world! So why was this happening to him!?

Naruto let out a grunt of pain as he felt all the chakra strings grab every bit of his body they could land on, tears of frustration and sorrow running down his face. He had watched Kakashi and Bee literally shrivel up and die before his eyes. His team was gone; Sakura had fallen to the jutsu and Sai was too low on chakra to last long as well. The Konoha teams had also died, their last words being tearful goodbyes and words of soothing to each other. 'Kurama, I need some help!'

"On it! Here's my chakra!"

Naruto's Nine Tailed Chakra Mode activated, empowering him with the might of the Bijuu within his gut. Unfortunately…that wasn't a very good idea, depending on how you look at it. Naruto cursed as he felt the strings tighten to the point where it was beginning to get difficult to breathe. "W-Why the heck isn't this thing coming off!?" He shouted, thrashing on the ground as the pain intensified.

A wealth of knowledge was flowing into him; experiences he had never gone through, meetings and scheming he had no idea had taken place, jutsu he had never heard of and several shinobi tactics he could barely understand. It didn't stop at that though; he also felt his mind recounting the memories of several different people.

Within the seal, Kurama was also assaulted with memories…the memories of his fellow brothers and sisters. He gripped his head, trying to lessen the flood of information as well as trying to figure a way out of their current situation. 'Shit…at this rate, we're all going to become part of the Juubi! What did that fucktard Madara do?!'

Outside, Naruto's body was starting to break down as well. He could feel his legs grow steadily hotter until it felt like white-hot flames were trying to burst out of them. His bones were making several disturbing and excruciating sounds that were drowned out by the roars of the incomplete Juubi. 'I-Is this it? Am I gonna die like this? No, I refuse to let it end like this…Ero-Sennin and Dad left their wills to me, to find the answer to breaking the cycle of hatred. I can't just give up! Not now, not ever!' With a supreme effort of will, Naruto forced himself to form a Kage Bunshin.

The clone nodded its head and started preparing a BijuDama, only for them to stop when they heard a voice they did not expect to hear again. "Naruto! Don't attack, you'll end up blowing yourself to bits!"

Naruto's eyes widened in disbelief as he found himself sitting in front of the other Bijuu once again. Like last time, they were with their Jinchuuriki placed on their heads. Turning around, Naruto was quick to notice an obvious change. "Where's Kurama? Why isn't he here?"

Son Goku, the Four-Tailed Ape, was the one to break the news to him. "Kurama is currently fighting to keep his form from breaking down into chakra to diffuse into the Juubi. We didn't contact him, since he needs his entire concentration on staying alive and in this world." His voice was rough and gravelly, sounding like rocks crashing into each other.

Leaping to his feet, Naruto started waving his hands wildly. "W-Well what are you waiting for?! Tell me what I have to do to help him out. Obviously you have an idea how to get out of this situation…right?" He questioned, his arms falling to his sides while his hopeful gaze fell on all of them.

Goku took a deep breath before he spoke again. "We do have an idea…but the price might be too high to pay." The ape shifted from one huge arm to another, avoiding the young Sage's curious eyes. "The Juubi is the focal point for the jutsu Madara cast…but we are what make up the Juubi. Instead of all of you being merged with the Juubi being the dominant presence, we can interfere and tweak the jutsu into making YOU the one who will benefit from this jutsu."

Naruto recalled the chakra strings that fed him knowledge from the other Shinobi. "You mean…that stuff that happened was your doing?" Surprisingly, he wasn't angry with them. They had done what they thought was best for the world to survive and he could understand why they did it. Out of all the shinobi, he was the only one they would actively help out and entrust their power to.

Matatabi, the Two-Tailed Cat, spoke next, her voice low and solemn. "Yes. We had no other alternative and it was the only thing we were capable of doing at the moment. However," Her gaze turned mournful and she averted her eyes. "If you go through with this…you may lose yourself to the other presences inside the Juubi. Or you may have a personality change…either way, you'll never be the same after all this."

Naruto blanched at that. He would never be the same? Compared to the alternative, which was the Juubi becoming complete and feasting on the civilians, that didn't seem like much of a price to pay. As if hearing his thoughts, Isobu the Three Tails shifted his eye on Naruto. "What Matatabi-nee means is you might be overcome by the nature of Madara and decide to conquer the world as well. Even if that doesn't happen, a part of all those killed in the War will be accumulated within you along with yourself."

Naruto blinked; when it was put that way, either situation was bad…still, Madara would have to compete with the other aspects of the Allied Force if he wanted to seriously corrupt Naruto. Sure he may end up being a bit more arrogant but it wasn't like it would be a bad thing…right? "Do it…but I'd like you to do something for me."

Chōmei was the one who asked the question. "What request is it that you wish for us to do? We may not be able to help with it but we will hear you out."

Naruto nodded his head, that was the best he could get and he was willing to take it. "When you come together once again…could Kurama be the base for the fusion?" Despite the fact that the Bijuu could not imitate quite a few human expressions, Naruto could definitely tell that they were confused. "Ever since his defeat at the Valley of the End, Kurama hasn't had the chance to actually be free since then. I-I would appreciate it if you made him the dominant personality in your own fusion." He finished, his eyes locked unto each of theirs.

All they could do was nod in silence as Naruto disappeared from their plane of consciousness.

-Physical World-

The Juubi sank to the floor, it's body disintegrating as more and more of its chakra was siphoned to the young Uzumaki. All that remained were its head and upper body, five outrageously long tails and the left arm. By now, all that was left of the Shinobi who had been present was their clothes; even Madara's Edo Tensei body had been absorbed into Naruto's continuously shifting new body.

It was mostly the same as his old one, though there were several differences. For instance, his fingers now ended with dangerously sharp claws that gleamed in the moonlight, his whisker marks had all but vanished, and his hair was longer than ever; in fact, it resembled his father's but was generally shaped like a lion's mane. His body had bulked up more muscle as well; enough to clearly define the muscles through his clothing yet compact and not overly ripped.

The beast gave one last howl as its consciousness was finally assimilated. With its job done, the Douka no Jutsu was released. No sound was made and the earth seemed to hold its breath in anticipation; would this being be its savior…or its executioner?

Naruto's eyes slowly opened, revealing themselves to the world. Black sclera, containing the eyes of the Juubi, gazed into the moon. His lips stretched into a disarming smile. "I made it…I'm still in control." He leapt to his feet and pointed his finger to the moon. "Take that, ya bastards! Uzumaki Naruto is the undisputed No. 1!"

A/N: Just so you know, Naruto will leave his world in the next chapter. He may not like it, but there are various weapons and items that he may need in his adventures. I'm giving Naruto five weapons to use: Samehada, Tetsusaiga, Bakusaiga, Kubikiribōchō and Madara's kickass war fan.

Harem for the story:

Erza Scarlet

Lucy Heartfilia

Tayuya-Can someone say 'redhead catfight'?

Konan

Samui

Mirajane Strausse

Juvia Lockser

Female Sasuke- I've always wanted to try this pairing!

Aaaaaaand…Erza Knightwalker-She's got the whole 'hot evil babe' thing going on. Plus, this adds twincest to the story…well, sorta.

Any complaints? Send me a PM. Next story to be updated after chapter 2 will be 'The Bijuu Shur'tugal'. Maelstrom Ashikabi is being pushed back to the middle of December; my inspiration needs a few more doses before I can continue the chapter.

Next chapter, Naruto tames the Dragon King and makes himself known to Fairy Tail. Please note that this is when Natsu and the others are younger, so no Lucy just yet. Naruto will also become younger due to the dimensional travel; he'll be slightly older than Erza, who will be 13 when Naruto appears in Fairy Tail.

Exams end in three days…can't wait for the reprieve.

MaelstromBankai.
