Chapter 1: Beginning of the End

War. That was the last ten years of Naruto's life was.

After defeating both Obito and Madara, Naruto thought the war was over and he could go back to Konoha to get 40 bowls of the food of the gods. He was tired. He wanted to mourn for his friend Sasuke whom took the hit so Naruto could finish the job. Alas, it was not meant to be.

The end of the Fourth Shinobi World War, which was the shortest war, led directly into the Fifth Shinobi World War, the longest war ever fought ironically. It was the smaller countries formed like Ame and Haze formed the Confederate of the Small Dominion against what was left of the Allied Shinobi Force. The Confederates wanted to expand their territory into the five great shinobi countries. So a night after the Allied Shinobi Force was slowly retreating back home to rest and grief for the fallen, news of the fifth war broke out when both Iwa and Kumo were destroyed.

Panic created a disorganized chain of command that allowed the Confederates to attack Suna as well. Because the Allied Shinobi Forces already took major losses from the previous war, they were forced to retreat to through Fire Country to Kiri. Weeks went by before the Allied Force was able to establish a successful counterattack to start to push the Confederates out of Fire Country. It was doing well, until Ame invented Chakra Rifles that started the Chakra Arms Revolution.

Chakra Rifles are created from two main components. Chakra batteries are storage seals that could store the user's elemental chakra and little of that chakra would allow the seal to continue to replenish the chakra. As a result, civilians could also fight as well even if they had small reserves. The second part is the Shape Barrel. It had seals that allowed shape transformation to create spheres of chakra. The result was an efficient weapon that shot mini Rasengans like bullets the size of a coin far distances mixed with different elemental chakras miles across the battlefield. The only downfall of this weapon that it took time to cool the Shape Barrel.

The definition of war changed soon after. The war were fought in trenches and it became who would control the most trenches the longest would slowly gain the upper hand. Both sides forced the advancement of Chakra Rifles until it became the sole weapon of choice for the shinobi. Weapons like swords and shuriken became useless as the rifle became more advanced to shoot faster and farther.

War takes something away from everyone. In this case, Naruto's naivety. Shikamaru drilled lessons into his head from war tactics to efficient ways to kill. For the first time, Naruto willingly committed the slaughter of hundreds of troops in a trench. It pained him to do this, but it was rationalized it as necessary to protect his precious people. After all, his father had done the same with a heavy heart.

On the night of October 10, Naruto and a squad of 10 shinobi, named Squad Dominion, made an attack on the outer part of the trench. Using his trusty kunai, he silenced two watchers with wind chakra in the trees before moving north through the trench, eliminating any enemies with his squad they found. Squad Dominion went through the sandy trenches quickly and quietly. It wasn't until a shinobi from Iwa died in front of him from an explosion that the mission took a turn for worse.

Shit!

Naruto quickly rolled away as the explosion from the artillery round that landed in the center of the squad, killing everyone except himself. He quickly got up and started waving signs to clear the dust.

Futon: Daitoppa (Wind Release: Great Breakthrough)

Pulling a kunai in his mouth, he dash forward into the sea of enemies, realizing he fell into a trap. If he was going to fall today, he was going to take as many of the bastards as he can, Zabuza Momochi style!

Its time for me to rest...

On October 11, the Allied Shinobi Force reported that Squad Dominion achieved their objective of cleaning the Western trenches at Suna, allowing them to establish a second front on the Confederates. The cost was Squad Dominion being listed as KIA.

Watching this all through a portal, was a white clothed figure that could be floating with a black staff and six round balls floating around him.

This man was none other than the fabled Hagoromo Otsutsuki, the Sage of Six Paths, and the God of Shinobi. And right now the man with two purple eyes observed his last descendant in the living world from limbo, the reincarnation Asura. And right now the man was watching a scene that made him feel utmost pride in, for the young Uzumaki who he's watch over since he was just a babe grow to become a powerful shinobi to even have the potential to exceed even himself. The boy had the godly potential to become one of the strongest the world would have ever seen if his life were not plagued by injustice and bad luck.

Though he didn't blame him the Uzumaki for not being strong, for if it was someone else, they would have been dead already.

This boy has such potential...its almost frightening...but I do find myself curious as to how powerful he would become if he were living… The deity mused to himself, contemplating on the case of Naruto Uzumaki.

He closed his eyes in thought of the young Uzumaki who had passed every expectation he had for countless times and then some. It was shocking how far and how fast the boy had gone but feels proud of him, for he felt like his true successor. Although he might not be as strong as his other descendants, he had the ability to do so in the right environment.

"I've made up my mind...but it's the boy's decision…" he muttered and thus with a shift of his hand came a portal that was black as the void. They circled before him that is as they slowly solidified. And what formed was the body of one Naruto Uzumaki only clothes in a white kimono with nine black magatama on the back.

Naruto opened his eyes when he felt a sudden chill go up his spine did he slowly look to where it was coming from only to see a figure floating in a cross-legged position. The man's purple eyes looked just like Nagato's.

Naruto grunted, propping himself up on his feet. So he really died again. Funny. Thought it would hurt more. He wondered how would hell would look like. He already knew he was no saint, killing hundreds in the war. Looking around, he saw blackness around him, illuminating the figure in white in front of him.

I hope my friends won't be sad at me for dying.

"Hello young Uzumaki, it is a pleasure to finally meet you...face to face…" the deity said to the young blond hair man, who quirked an eyebrow at the figure before realizing no hostile intent from the man.

"Um, yeah nice to meet you too but who are you?" he questioned as he thought he would be seeing the Shinigami who wasn't too happy at him for getting away the first time around. Yet for some reason, he felt this man could answer his unasked questions for he gave off a feeling of unattainable wisdom that no other could hope to achieve.

"My name's Hagoromo Otsutsuki." Naruto's eyes went wide. He knew all too well of the being in front of him was the first shinobi to walk on the planet. Madara always ranted about him in his evil villain monologue.

"I see...But aren't I supposed to see the Shinigami cause I'm dead? Unless this is the afterlife…?"

"Well that all depends on you actually. You see, I have been watching you my descendant and I feel proud of your perseverance through your hard life. And that is why I will allow you something no one else in history of mankind has ever gotten and that is a second chance. A new life where you can start over, although not in your world or dimension due to your soul signature truly leaving the plane of existence…"

A second chance? A new life? It was almost too good to be true, he'd been fighting for a few years but he felt as if he had been fighting for his entire life. Fighting non-stop exhausted him more than anyone else ever thought always needing to fight to protect himself, and friends against the Confederation. But at times, he wished be able to not be stressed with the weight everyone put on him in his genin days with Sasuke.

Sasuke...I still have not thank him for sacrificing his life for mine. Just like on our first mission...But, he is willing to give me a second chance...although it pains me to not be able to see my family and friends again...I'd like nothing more than to have another chance…

The Sage of Six Paths could see the boy thinking on his offer and smiled. He made his decision.

"So Uzumaki...what is your decision?" he asked with a grandfather voice. Naruto closed his eyes before letting out a small sigh. Slowly he looked up at the deity and in that moment he spoke, speaking the words that would forever change his life.

And for the better…

"I...Accept…" he said thus making the Sage in front of him give a small nod in confirmation that he acknowledged his decision. An aura that surrounded the Sage covered Naruto and wrapped around him like a cocoon.

"Very good then...best be on your way then Naruto, or Obito Uchiha...and best of luck...my child…" and before Naruto could say a word, he felt himself being sucked into a portal and lost consciousness. The last thing he saw was the form of the Sage of Six Paths giving him a smile.

Seeing him gone, the deity let out a small sigh as he slowly became particles. Now the mantle has been passed on to his last descendant. Smiling at the thought, he slowly faded away, ready to meet his brother Hamura in the afterlife along with the rest of his clan.

In an alternate universe, Kakashi and Rin watched how their teammate Obito got buried under an Earth jutsu. In his anger, he released his newest jutsu, Raiton: Chidori (Lightning Release: One Thousand Birds), on the Iwa Shinobi for vengeance while Rin simply watched the rock pile where Obito got buried.

And there was nothing to do. As Kakashi and Minato cleaned up the rest of the shinobi, Rin ran towards the pile of rocks and started to move as many rocks as possible, regardless of the cuts on her hands.

"Rin! Stop! He's gone...Obito...is gone…" Kakashi said solemnly with a clenched first.

"No! It can't be true. It can't." Rin cried in agony as she slump down to the ground and her lifeless eyes stared as the pile.

Minato simply bowed and gave a moment of silence for failing to protect his students before dragging his two students back to Konoha. "We have to go now. We have to return back to Konoha and tell the Hokage what happened here…"

Team Seven looked back one more time at the place where Obito's body rested with tears flowing down their eyes. They turned and walked.

Its going to be a long walk...Rest in peace Obito… Minato thought.

~ o ~ X ~ o ~ X ~ o ~ X ~ o ~ X ~

When Naruto's 26-year-old soul connected with Obito's 12-year-old soul, the two fused together taking personalities of both Naruto and Obito. But since Naruto lived longer and had more experience in life, Naruto's personality slowly overrode Obito's.

For a few minutes, all was silent in the world between the material and spiritual world as the essence of the Uchiha and Senju descendant became one once more. This allowed the Yin and Yang of the Sage of Six Paths that was once separated in his descendants to reunite and form fragments of Shinju chakra, leftover chakra from Hagoromo being the Jinchuriki of the Juubi.

Once the souls finished merging, it slowly dissipated in Obito's buried body. The chakra that accompanied the soul slowly started to integrate itself with the chakra pathway system and the 361 tenketsus. Slowly, what was left of Obito's chakra was recycled for the body to produce Shinju chakra. The new foreign chakra slowly spread throughout the body. It destroyed cells that rejected the foreign substance: skin cells, muscle cells, organ cells, immune cells, and blood cells. The surviving cells were contaminated with the new chakra to produce more powerful and durable cells.

If one saw Obito's body during this process, they would see the body twitching a lot underground. They would hear multiple bones pop painfully and mend back together. They would see pieces of skin would fall off quickly to be replaced with paler ones. They would notice Obito's black hair grew longer and had some strands of grey. But what was most outstanding was that Obito's body was slowly getting longer and wider, making him looks like a true teenager of the Uchiha Clan.

Once the fusion of Uchiha and Senju was completed, two red Sharingan eyes opened and glowed in the darkness. Then two tomoe evolved into three. The Sharingans were spinning in darkness rapidly before evolving into the Mangekyo Sharingan, three stretched triangles evenly spaced around the pupil that each curve at the top around the eye to form a circle.

Naruto and Obito's eyes started to bleed as they saw a distortion in space. As the body buried underground began to put chakra into the Dojutsu of the body, the Shinju chakra hummed as it flowed and connected with the eyes. Obito said one word, a word that would save him countless times and make him an S-class shinobi of Konoha.

Kamui (Authority of the Gods).

Then the body of Obito's body swirled and got sucked into a dimension.
