Hey guys! I'm back with a new chapter :) Anyway I don't own Naruto and this is going to be eventual slash so if you don't like don't read and just fyi I'm not going to go exactly with the main story. Naruto is going to be right on par with Sasuke at the beginning instead of catching up eventually. I hope you like it!
Over the next few weeks the makeshift family became more like a real family. Kakashi and Iruka grew to love the boys as sons. Since they never found out the boys age or birthday the two decided that their birthday was the day they were found at the gates of Konoha and that the boys were seven years and Iruka thought that now would be a good time to start teaching them the ways of the Shinobi. Since Iruka was a teacher, the task of teaching the boys theory was left up to him. While Kakashi was better at the practical side of things so he would teach the boys how to use the chakra inside them.
During the first day of their lessons with Iruka, Naruto and Sasuke learned exactly what chakra is. Chakra is vital to even the most basic of techniques, its the moulding of physical energy present in all body cells and spiritual energy gained from exercise and experience. Once moulded, it can be channelled to any of the 361 chakra points throughout the body. Through the use of hand seals, chakra can be manipulated to do things that couldn't be possible otherwise, like walking on water, breathing fire, or creating illusions. It seemed like the boys were naturals for this information because they soaked it up like a sponge and they were just as proficient in the practical lessons with Kakashi.
Kakashi had never seen such talent in any body this young before. Sasuke had an unusual talent for the fire element and he had amazingly fast reflexes as well which made Kakashi wonder about a possible special skill long lost except for one person, him. Naruto, on the other hand, had a seemingly unlimited amount of chakra inside of him. Also, he had an almost unnatural skill with clones. The first time he had taught them the cloning jutsu, which he normally wouldn't have touched until later but he knew the boys could handle it, Naruto had added an extra hand sign and used the highly guarded secret jutsu called the Shadow Clone Jutsu. This was a highly guarded secret of Konoha and Naruto had used it at the age of seven. With one year left until they entered the academy Kakashi knew that these two had amazing futures ahead of them as Shinobi. Naruto was also highly skilled in the wind element and was displaying amazing strength in it for his age.
Kakashi and Iruka were talking one night after the boys went to bed and they couldn't believe the powers these two were showing at such a young age. Kakashi started talking about the signs of a bloodline that Sasuke was showing and it made him wonder if this could help them discover where the boys came from.
Kakashi was with his team in the middle of the forest on what should have been a routine delivery mission which had quickly turned sour. Their team's Jounin leader was fighting one of the stronger enemies and Kakashi, Obito, and Rin were forced to deal with the others. During this fight they had become trapped in a cave and Obito had been crushed by the rubble. It was a well guarded secret that Obito was not of this world. He was from a world called Tenebris and his full name was Obito Uchiha and he was one of the powerful panther demons who had been banished to the human world.
He had a powerful bloodline in his eyes called the Sharingan and with it he was able to copy his opponents hand signs perfectly and be able to perform the same jutsus as them. There were further powers involved with the Sharingan but Obito didn't have those powers and so never mentioned what they were exactly. The only person who Obito told the secrets of the Sharingan to was Kakashi and that is because Kakashi was his best friend. Obito was dying and during the battle Kakashi had lost sight in his left eye. "Kakashi, my friend, take one of my eyes, use the power well and help protect Rin and Konoha."
"No Obito, I can't take it. I don't want to take one of your eyes for my own gain," said Kakashi who was crying.
"Take it, I have no need for it where I'm going but if another like me shows up, then train him, teach him the ways of the Sharingan and tell him about Tenebris since it was only a fluke that I remember," said Obito with his final breath. Then Obito died in Kakashi's arms. Kakashi wanted to argue and refuse the eye but since it was the dying wish of his best friend he felt that he couldn't refuse. So, he asked Rin, who was a medic, to take Obito's eye out and put it in his left eye socket. Rin went to argue but Kakashi gave her a look that said to not argue and just do it. Then in a few minutes Kakashi had the eye of Obito and the power of the Sharingan.
Since then, Kakashi has been on the lookout for another with the symptoms of having the power of the Sharingan and the amazingly fast reflexes were the very beginning of the Sharingan. There were a few more signs that Kakashi needed to see to be sure but Sasuke even looked like Obito. Then he got to wondering, if Sasuke is from Tenebris then is Naruto from there as well and what did these two boys do that was worth being banished at such a young age?
