Chapter 1

Timeline: 4th Great Shinobi War

It's been a few months since the war had started. Many shinobis had died one after the other. The cause of this situation?

Uchiha Madara: The man who was once considered to be the strongest ninja next to Hashirama and was resurrected from the dead. He was so powerful. The shinobi aliance which was made up of the five great elemental nations were slaughtered by him alone.

He came back from the afterlife with an ultimate plan: the Mugen tsukoyomi (the Infinite Moon Reader). A plan that could befall the entire shinobi nation into a state of supreme torpidity.

But in order to succeed in his plan, he needed to overcome a few obstacles.

First, he needed to be resurrected.

Second, he needed to gain the rinnegan.

And lastly, he needed to capture all the bijuus and reform the Juubi (Ten tails).

He was able to succeed and achieve the first two, and was nearly completing the last one. He was able to capture 8 out of the 9 bijuus and extract them from their jinchuriki (human sacrifice).

Unfortunately, he wasn't able to succeed in capturing the last bijuu: the kyubi. The jinchuriki of the kyubi was apparently a very powerful shinobi.

The shinobi, who at such a young age, was already able to do something, that even he could only have done at his prime. The boy was able to gain the trust of the kyubi and was able to have a full control over his chakra, making him a bigger threat than the other jinchurikis. He was known to be the 4th hokage's son, the savior of konoha and lastly, Ashura's reincarnation. His name was Uzumaki Naruto.

Sadly, Naruto wasn't the only threat that caused problems to his plan. There was another shinobi by the name of Uchiha Sasuke, who came from the same clan as himself. The boy's feats weren't far from that of Naruto's. Sasuke Uchiha had not only attained the mangekyou sharingan (telescopic copy wheel eye) but was also able to evolve it to its next state; the eternal mangekyou sharingan. Despite his youth, and just like Naruto, Sasuke was also the reincarnation of Indra, which happens to be Ashura's brother, and was able to gain the rinnegan of the rikudo sennin.

These three shinobis had fought for months, causing destruction by leaving the lands they fought on, dead. They were preparing for their ultimate battle, studying any flaws of the enemy until...

Madara started coughing blood.

He had been fighting with the two young ninjas for a few days now. The combination of the rinnegan and the kyubi's chakras were taking too much of a toll on him. Although it was evident that the other two were having as much difficulty as he was, he wasn't certain if he could even use a single mangekyou move by now.

He slowly rose to his feet, getting himself ready for his last jutsu. Despite the extreme pain that he was feeling, he still wasn't able to escape the excruciating pain that was raging from his backside.

"Arrrghhh!"he screamed, as he slowly turned his back to see zetsu backstabbing him with a scroll?

He was too shocked to realize that his body was slowly changing its form and he was losing consciousness as seconds passed, until there was no longer Madara Uchiha, but a white-kimono-dressed-woman with white long hair and byakugan eyes and a mangekyou rinnegan on her forehead, instead of him..

" .Happened?!" asked Naruto in panic. He thought he had just seen the weirdest thing that he could have seen in his whole life.

"I don't know! Did he transform into something…" Sasuke was quick to reply, while scanning the new creature in front of him carefully, preparing for any sneak attacks.

"I am Kaguya, the god of all chakra," the goddess had explained herself to the two mortals who were just looking at her like they had seen a ghost. "I have come back to this world to take the chakra from you people. Let's start with you two," she continued. She threw two bones made of chakra in fast speed, gliding towards them.

Meanwhile…

Naruto blinked his eyes. He was somehow transported to some dark room with a few candles glistening in the dark. He turned to his right to see Sasuke glancing back at him, looking confused.

"What happened?" asked Naruto.

"I don't know. Dobe Madara just turned into a freaking goddess... And stated that he would take the chakra back from the human race!" replied Sasuke.

"Well, I can explain that…" said a third voice in the room.

Both boys turned their heads to the direction of where the voice had come from.

They saw a man in his late 60s, clad in a white trench coat with magatama signs on his back, and holding a staff in his hands. This man was Ootsuki Hagoromo, the sage of the 6 paths, more known as Rikudo Sennin.

"Apparently, I have sent the both of you to my mindscape, where time flows slower than the outer world," said Hagoromo while tapping his staff to the ground.

"I would like to talk to you about that woman who you're gonna fight…" Hagoromo continued, "…about how to defeat her and the risk of beating her. But before that, I would like to teach you two some history…"

"First, I remember telling you about the origin of chakra, right?" he asked the two boys in front of him.

"Yes, you did. It was you, after all, that gave humans chakra," answered Naruto, in a rather amused voice.

Making a spark in the air, Hagoromo replied. "Yes, that is what people know but that is not enitirely true. The truth is that there was once a woman, from another dimension who was capable of doing things without the use of chakra."

"Another dimension?" asked Sasuke. He wasn't sure if he were to believe the sage or not. It's just that he also couldn't accept the fact that there were other worlds that are capable of doing things his world couldn't.

"Yes… I don't know where and how, but that exact woman had the power to kill humans with just a glance of her eyes. One day, she fell in love with a man and promised him to bring peace to the world which was, at that time, filled with wars. That man was my father. So that goes without saying that this woman right here, Ootsuki Kagura, is my mother in blood."

"Wait what?" Naruto freaked out. "You're actually an alien?!"

Both Hagoromo and Sasuke were twitching their eyes hard, listening to the boy's childish thoughts.

"No, I'm not. And neither is she. She is a jist from another earth who has powers different from this world..." Hagoromo quipped. "Anyway… Not after she got pregnant, for some unknown reasons, Kaguya had betrayed the Humans' faith, including my father's, by eating the shinju fruit from the shinju tree. That tree was an ancient tree that was protected by my father's family for generations. By eating the fruit, she was the first person in this dimension to ever wield chakra. From then on, and by using her chakra, she was hailed as a god, stopping wars and fights all over the world. A few months after, she gave birth to me and to my brother Ootsuki Hagoromo and Hamura. As we grew into adults, we inherited her power and respected her for views of peace and promised to follow her legacy. Although we were able to maintain peace throughout the world, we weren't able to maintain the peace in the family."

"The reason is quite stupid... I have given chakras to humans, hoping for them to maintain peace and live an easy and peaceful life. Unfortunately, I wasn't mature enough to realize that giving chakras to humans was like giving a weapon to them. War had increased in the same year because the human had satrted fighting for power, this time by using the power of chakra, which in turn, brought nothing but chaos to the world."

"My mother, Kaguya, was enraged of my actions and decided to seal all chakra from the human race, but me and my brother thought that she was going crazy, so we had to make a decision. We were to choose between watching the humans fall into their own downfall or seal our own mother's chakra and body forever. We decided on the latter. Along with my brother, we sealed our mother in the juubi form in the moon, hoping that no one would ever free her from her long sleep.

"If you would just listen to this, you would think, it's a happy ending… but no, it isn't... We weren't able to find zetsu, a creature made of my mother's will. It waited for years to find a container that was capable of reviving my mom and by the looks of it, he was able to succeed on his plan..." Hagoromo related.

"Enough with your excuse! We don't need such long explanation on how you failed anymore!" shouted Sasuke suddenly that surprised the other two in the room. "All I want to know here is how to defeat her and finish this once and for all" he continued.

"Sasuke!" Naruto corrected.

"No, I know he's right. I'm just making excuses for my faults..." sighed Hagoromo. "The only way to defeat my mother is to seal her. You can't just kill her because she is that powerfull..."

"Hey, that's easier said than done," exclaimed Naruto.

"But this time, it's different, Naruto... This time, the two of you would seal Kaguya by yourselves, separately. One of you would have to seal Kaguya's power and soul, while the other would have to seal her physical dead body. Also, the one with the soul would have to find another dimension where no chakras exist so as to prevent the soul from finding another container to stay in, if the jinchuriki dies," said Hagoromo in a heavy voice, not liking the idea that was coming from him.

"Wait, so what you're telling us is that, we have to give up our own lives and dreams by going to another dimension and peacefully die there with the power of Kaguya?" Naruto fearing for his own life. He thought about the unfairness of the situation to both him and Sasuke.

"I'm afraid you're going to have to decideon who would leave, now ," Hagoromo continued. "You guys don't have enough time."

The two boys were looking at each other with their pained filled eyes, both thinking of how painful it would be to leave this place and giving up everything that they had worked up for.

After a long silence, Sasuke decided to break the silence and spoke. " Hagoromo, i wou.."

"I will!" interupted Naruto, with determined eyes looking up to Sasuke, who as expected, was shocked.

"Dobe, how about your childhood dream of being the hokage of the village? You lived your whole life as a ninja just for that…" said Sasuke.

"You know what, I think I'm okay with it… I wanted to start over, anyway... That's something that I don't think I would be able to do in Konoha…" Naruto explained further. "Being a hero in another dimension, don't you think it's awesome, Sasuke?" asked Naruto in a happy tone but Sasuke caught hold of the sadness hidden in it. "Besides, you have an ambition to complete, too, right? Reviving your clan… Now, that's something that you can't do where chakra don't exist." Sasuke stiffened at that comment. He knew in his heart that it was true. He nodded to Naruto to express his agreement, but with guilt washing him all over.

"I guess it's decided, then," Hagoromo put his hands over the two ninjas' heads. "I will send you back to reality. From then on, you would have to seal her by yourselves, understand?"

Both nodded. And with bright flash… They opened their eyes.

Fight just like in canon, without Sakura and Kakashi.

Naruto was finished absorbing the soul and power. He almost puked with all the knowledge flowing through his brain. Not only that his eyes were now red with rings covering them, 3 magatamas in one ring, the mangekyou rinnegan. He felt so different now... He was filled with foreign energies that was too powerful that it hurts.

"Man, that's weird... Was it always like this with the sharingan, Sasuke? I'm so dizzy just looking at you," laughed Naruto.

"At first, yeah… but you'll get used to it," replied Sasuke, exhaustion evident in his voice.

They were both smirking at each other for a while when Hagoromo came back, ripping through the space.

"I guess, you two did it,"he stated.

Hagoromo looked at Naruto and heaved a heavy sigh again. "I guess you have accessed the eyes and the chakra of the shinju, Naruto. You now have the power that ties or go higher than mine. I hope you have great luck having it."

"Thanks, old gramps..." Naruto accepted. "I got one question though… How about Kurama? What would happen to him and the other bijuus? Wouldn't they be reformed into juubis one day?"

"You don't have to worry about that, child. The bijuus' chakra are linked with yours. The moment you leave this world, they would be sealed into you, as you leave this dimension," answered Hagoromo.

"Really, gramps?" Naruto said.

"I'm not gramps, but I can confirm that" answered Kurama in his mind scape.

"Kurama ! Atleast I've got a few friends to live my life with since you're there, " Naruto sighed in relief.

"I guess this is it, Sasuke," Naruto smiled. Sasuke smiled back and said, "Dobe, take this before you go…" as he handied Naruto a sealed scroll and handed it to him. "It's just a few jutsus that I have copied with my sharingan. It may help to know a few more manipulations, right?"

"Yeah, thanks... Have luck reviving your clan..." and right after Naruto said that, Hagoromo opened a black portal, signaling him to go in. Nodding, Naruto had one last look of the elemental nations, before he dashed through the portal and disappeared forever from the shinobi world.

Thanks for reading! I'm not abandoning Back to the past okay? And please give me reviews! I really need them! Thanks again!
