Naruto the eldest son of Minato Namikaze The Yellow Flash and Kushina Uzumaki The Red Death, he has two sisters that is Mito Uzukaze and Naomi Uzukaze and one brother that is Menma Uzukaze. After the Kyubi attack Minato was able to seal the chakra of Nine Tails in the three newborn siblings and the soul in Naruto Uzukaze.
After 8 years on the birthday of Uzukaze siblings, Mito Uzukaze was named the heir of Uzukaze clan making the Naruto the former member of Uzumaki and Namikaze clans or Uzukaze Clan and apprentice of Kushina Uzukaze and Naomi became apprentice to Tsunade The Slug Sannin and Menma became apprentice to Orochimaro the Snake Sannin and as always ignoring young Naruto. This upset young Naruto to unimaginable degree . He couldn't take it anymore so he decided to leave the village so he ran towards the gate of Konoha unnoticed by everyone because they were too busy focusing on the ceremony.
After few hours of running in forest of death, tears was dropping from his eyes as he keeps muttering to himself. He stops besides a tree.
"Why?...Why?...Why they did do this to me. Am I that worthless. What harm did I give to them" said by Naruto who had just been standing in front a tree, his head on the tree.
"WHY MEEEEEEEEEEEEE" roared by Naruto his eyes turned silver for a moment before before going unconscious due to energy exhaustion.
Many would wonder why Naruto was acting like this. But its obvious that Naruto was doing all this because he was not only neglected by his parents and by his godfather and godmother for 8years for his siblings but was disowned by his own Biological Parents all because of a prophecy mentioned by the toad's elder when Minato was on journey to Mount Myoboku to learn sage mode. The prophecy was that "One with the assistance of his/her followers will bring great change to this world and will save the world from great evil". After that Minato along with Kushina and the Slug and Snake Sanin considered Menma, Mito and Naomi as The Children Of Prophecy due to chakra of the Nine Tailed Fox sealed inside them and thus neglecting Naruto in the process due to him possessing only the soul of Nine Tailed Fox. From that day on his siblings were trained and Naruto was neglected and was considered as demon reborn, monster and other names like Disgrace of Uzukaze Family etc. and was bullied injured by the villagers for it.
On Naruto's 6th birthday or should you say hell day, he was chased by a mob of villagers with weapons with them . Naruto kept on running for an hour but it was too much for a 6th years old child as he collapsed to the floor and soon the mob of Villagers was near him. One of the villager threw a kunai at him hitting him on his arm other threw a kunai at his legs and soon the mob of the villagers started assaulted him with various weapons but a conscious inside Naruto could not take it anymore and began to took over the body of Naruto . That consciousness was The Nine Tailed Fox who had a little bit chakra retained to himself after 6 years. Naruto wounds were healed instantly and as he rose staring the villagers with red bloody eyes and red aura surrounding his body scaring the Mob of Villagers before Naruto in Nine Tailed Fox control sped in red flash cutting the heads of the villagers who were about the strength of 30 Men. He then sped to a forest near and stops there before leaving control of Naruto's body. The red aura surrounding Naruto dissipated and his eyes changed from bloody red to silver for moment then reverted to sky blue ocean eyes.
Since that day 9 tailed fox who introduced himself to Naruto as Kurama and offered him some training to defend himself to which Naruto agreed as they became Teacher and Student. Naruto also came to know about the real reason Kurama attacked that was a Uchiha controlling him to attack the village. They trained for two years and during that time they came to notice a strange pure and calm power deep inside Naruto and sometimes Naruto eyes flashed silver and dodge any attack coming from forward whenever he left his mind blank but it lasted only few seconds before Naruto would go unconscious. They came to understand that power and named it Ultra Instinct.
"Its hard to face the harsh reality of this world kit" said by Kurama to which Naruto remained silent.
"I know how you feel Kit. But regrets only makes a person weaker. You are stronger than this kit. If you want to change this world then brace yourself and do not be such a cry baby." said by Kurama.
"HOW CAN I BE STRONG HUH KURAMA! HOW CAN I MOVE ON LIKES ITS NOTHING. THEY DISOWNED ME,NEGLECTED ME,BULLIED ME, INJURED ME. HOW IN THE HELL I CAN JUST MOVE ON" Shouted by Naruto.
I know its not easy kit but look at me I have lived for ages and suffered pain through all that time alone. Did you saw me cry or yell about it that it is unfair for me. I lived on and found you as a student why because I am not weak. You...are not weak I believe in you. You are not alone like I was Kit. Said by Kurama.
"I...I am sorry Kurama. I had never thought that..." Said by Naruto but was interrupted by Kurama
"Its okay Kit now you will move on and train even harder and show this world who Autonomous Naruto is. Make me proud" Kurama said.
Naruto wiped his tears and said: "Hai Kurama I will make you proud and show the world who AUTONOMOUS NARUTO is. Believe that"
"That's my kit" Kurama said.
So that is it folks. The first chapter of Autonomous Naruto. In this fanfiction Ultra Instinct works differently and has few abilities which will be mentioned later on. So review it folks. Pairing maybe Naruten or Naruita Brotherly bound or both of them.
