I do not own Naruto. Naruto and all of its characters belong to Mahashi Kishimoto. If I did own it, the story would have been a little different. Please read, review, and enjoy.
Prologue
In the modern world, there are such things that we as humans claim to be fictional, non-existent, or impossible to do. Such as jumping off buildings or trees and landing on the ground without breaking a single bone; and then there's being able to spew fire out of your mouth or punching someone with so much force that the person goes flying over 100 ft and killing them instantly. Little do we know however, such things exist underneath our very noses.
We all know the story of the Sage of the Six Paths giving birth to the ability to use jutsu and being the first jinchuuriki ever by containing the Ten-Tailed Beast inside of him. There was something else that he discovered though. The Sage had discovered our world, and how to travel back and forth between the two worlds. Fascinated by his discovery, he recorded everything that he had learned of our world on a scroll and made sure to keep it safe. When it came time to split the Ten-Tails into the nine different tailed beasts and name his successor on his deathbed, he told the youngest of his two sons about his discovery. He told his son to keep the scroll safe and make sure that his older brother did not learn about it. Promising to his father that all would be kept safe, the Sage of Six Paths named his youngest son his successor, beginning the ancient feud between the descendants of the two brothers: the Senju and the Uchiha.
As the years passed by, and the conflicts among the different ninja clans continued on, a rogue Uchiha that had become friends with the Senju discovered the scroll that the Sage of the Six Paths had made. He read every detail that the Sage had written and made sure that he had everything memorized, because he had formulated a plan. This Uchiha whose name was Hajime Uchiha, a pacifist, wanted to start a new beginning for the Uchiha and any other clans that wanted to follow him by traveling to our world and living there. He proposed the idea to Hashirama Senju, the future First Hokage, and liked the idea of starting a new beginning. The problem was that Hashirama didn't fully understand what Hajime was saying. Instead of helping Hajime go to our world, the Senju and the Uchiha ended their fighting and formed the Hidden Leaf Village Konoha. Hajime did not give up on his dream though and decided to continue with his plan anyway. Gathering other Uchiha members, along with other clans that were becoming extinct, prepared to leave the ninja world and travel to the "New World". Before leaving, however, Hajime gave the scroll to Hashirama and told him everything about it. Telling him to keep it safe from Madara Uchiha, he entrusted the scroll to him and with that departed with his followers to our world. The First Hokage, his brother, and top clan leaders of the village were the only ones to know about this scroll. With that, they locked it away with the forbidden scrolls where it rested for decades. And so without anyone else's knowledge, the Uchiha, the Yuki (Haku's clan), and others had began a new life in our world. They continued to practice the ninja arts and formed their own village together called: The Hidden Shinobi Village. Hajime Uchiha was the first ruler of the village, who ruled the village with the The First Hokage's Will of Fire philosophy. Hajime had attained the Eternal Mangeyko Sharingan through other means other than killing your best friend. With this new ability of his, he was able to live eternally on Earth and decided to act as the pathway to travel between our world and the ninja world as his retirement.
The rest of the world, both ours and the other, continued with their daily lives without knowing about each other. Until one day when fate plays out the meeting of the two worlds for the first time without it being a secret. The existence of both worlds will become known to each other and history will be changed forever. And it all started with one Naruto Uzumaki trying to pass the academy.
