Prologue

In a cliff overlooking a beautiful valley stood a man. He looked to be around his 20's but his eyes spoke of knowledge and experience beyond any mortal could hope to grasp. He was around 6 ft tall and his spiky hair which flowed behind his back reached just below the waist. The sun kissed blond hair he had in his teenage years had gradually changed into the ash white hair he was currently sprouting.

His face was clean without any markings and had changed to look more like his father 'Namikaze Minato'. The 3 pairs of thin whisker marks having faded after all the nine bijuu had merged with him. The tattered white robe he wore reached just below his shins and was purple in the inside. On the back of his robe were nine magatama (3 rows and 3 columns).

And the most prominent feature he had were his missing right arm and his eyes. The eyes he was gifted with after the death of his best friend and rival 'Uchiha Sasuke'. The left eye had the original 'Juubi's Rinnegan' and his right eye was the 'Eternal Mangekyou Sharingan'. In his left hand he carried a six ringed 'Khakkhara'.

This was Uzumaki Naruto, 'The Demon Child', 'Number One Unpredictable Knucklehead Ninja', 'Child of Prophecy, 'Savior of the World' or the moniker he went by now "The Last Guardian of Ninshu". Which was weird because there were only two guardians since the age of shinobi. The first being the creator of Ninshu and his mentor Ootsutsuki Hagoromo a.k.a 'Sage of Six Paths'.


It had been an uncountable number of years since he took over the role of the 'Guardian of Ninshu' from his mentor and guarded the mortal world, making sure the horrors like the 4th Shinobi War wouldn't repeat itself. But now his responsibility was finally coming to an end. The planet itself was starting to die. He couldn't believe that he had managed to outlive the elemental nation itself. He still remembered the last words his mentor told him when he took over his role.

Flashback Start

It had been a long 2 years of training as a guardian since the end of 4th Shinobi War but now it was coming to an end. Naruto was kneeling in front of a bed with a sad expression in his face. His mentor, who was laying in the bed was dying.

Ootsutsuki Hagoromo looked towards his pupil and couldn't help but see his own son Asura in him. He still wondered if he didn't have his responsibility as the Sage and trained and raised both his sons Indra and Asura then would they have turned out like Naruto. With a solemn look on his face he started speaking.

"Naruto, My student. I have taught you everything I could. Now the world is in your hands. Protect it like you would protect your friends." Said the Sage with a tired voice.

"Of course, Jiji. It's a promise of a life time." Replied Naruto who had tears in his face.

"It's been wonderful teaching you Naruto. Now my time is coming to an end. I have lived a long life and now it is my time to enter the cycle of reincarnation. Remember what I taught you Naruto. Be patience and less reckless. Think before acting. Even though the 'Juubi's Eyes' and the chakra of the bijuu makes you immortal it doesn't make you invincible. Now take care my son." Said the Sage with his final breath and slowly closed his eyes. With a small smile in his face he died.

Naruto started sobbing. Now he was truly alone in this world.

Flashback End


Since that day he had lived alone. When he had first started his training he had wondered why he must act like he was dead to the world. And the Sage had replied simply by saying that he would understand when the time came. And understood he did. Not even 25 years later people he knew and who knew him started dying. First was Tsunade, followed by Kakashi and so on. Every time someone he loved died, he would attend their funeral in a henge. He wouldn't cry. He couldn't afford to cry.

It was a sad existence. But he carried on. In his countless years of living he had come to master every Ninjutsu, Taijutsu and Fuinjutsu. Unfortunately the only Genjutsu he could perform was Kokuangyo no Jutsu and the techniques of his sharingan. It had been a really hard task and he had to modify every justu so that he could use it with only one hand. Even with only one hand he now was as the mortals would say 'Godlike'. His missing arm had really hampered him and still did. He could regenerate it if he wanted to but he kept like it was to never forget his purpose and the reason why he took the role as the 'Guardian of Ninshu. And now the end was near.

For the last century every living things were slowly dying. Forests were corroding and Lakes were drying up leaving only a barren landscape. Naruto had been making plans to escape this plane of existence to search for other dimensions. After his fight with Ootsutsuki Kaguya, he had learned the existence of other dimensions and during his time as the guardian he had experimented with the Juubi's Eyes to search for any dimensions that had sentient life. And finally he had found one. As he was preparing to leave various mountains erupted leaving a trail of ash and smoke and lava overflowing. He knew this world didn't have long.

He concentrated his chakra in his left eye and the nine magatama started spinning. After focusing to pinpoint the sentient life in other dimensions, he softly said "Kamui". The very fabric of reality warped itself around Naruto and he was gone.
