AN: Some characters will be slightly OOC in this story eg: Sasuke (not by much but he will accept Naruto slightly more) and Jiraiya (he will take training Naruto seriously, seeing as in the three year time skip it seems he learnt very little he will learn more then and the month training for the chunin exams.
I will also use some English and some Japanese names for jutsu, I know hardly any in Japanese so its easier than looking up.
There also will be no full scale invasion at the chunin exams, only Orochimaru and some sound ninja will attack (Suna did not participate)
Chapter one: Naruto obtains sharingan!
Team seven's mission could be considered a success. At least to shinobi standards. The threat to the bridge builder was over, the bridge would be finished soon and they could go home. The problem however, was the seemingly soon to be dead Sasuke Uchiha lying on the ground. This happened after a battle with Haku, ice release bloodline wielder. While this was happening, Haku and Zabuza's employer Gato came to betray them, this was stopped by Zabuza at the cost of his own life. However the battle was done, Haku had already inflicted the wounds to Sasuke and he seemed most likely to die. He looked up to Naruto and said "Dobe, find my brother, kill him for me, do this as my final wish. I ask you because I guess your the closest thing I could a friend." He turned to Haku "Your trained in medical things right?" When he received a nod he continued "Transfer my eyes to Naruto, they will be useful." Haku nodded and knocked Naruto out to begin the transplant.
The transplant was complete, the eyes were transferred to the others body, Naruto's eye were now red with one tomoe in one eye with two in the other. Sasuke's eyes were now blue. However once transferred, Haku noticed what appeared to be red chakra leaking slightly from Sasuke's new eyes. It was only small amounts but it seemed to be healing Sasuke's injuries! Soon enough he had healed enough to survive. He slowly reopened his eyes and instantly remembered what happened. He turned to Haku "Transfer them back, I get the honour of killing Itachi, I need those eyes." Haku sighed but nodded. Soon enough the eyes were swapped back.
When Naruto opened his eyes, he noticed he was in Tazuna's house again and jumped up in fear of Sasuke's death being true. He looked to his right and saw Sasuke's seemingly lifeless body. It was at this point that he noticed his eyes were hurting but before he could check it out his sensei appeared. "Good to see you okay Naruto, don't worry, Sasuke is fine." This relieved Naruto greatly. He then said "Sensei my eyes hurt like crazy, can you look?" He nodded and walked over to look but couldn't see anything wrong with them so he lowered his headband to see if it was a genjutsu used by the ice wielder back in their fight. What he saw shocked him greatly, there appeared to be a buildup of chakra that was different to Naruto's there. He then said "Naruto channel chakra to your eyes." Naruto did so and Kakashi watched amazed as his eyes seemed to darken slightly and instead of his pupil there were three white tomoe in each eye. He only managed to breathe out "Amazing..." Naruto he repeatedly asked what it was.
Kakashi spent the next hour about how his theory was during the temporary eye switch some of Sasuke's residual chakra leaked into Naruto and somehow activated his own version of the sharingan, for whatever reason. After this they both went to sleep and agreed to do nothing until talking to the hokage.
The next week went lazily, Haku visited one last one last time as he managed to survive their fighting. He was off to the rebellion for kiri. Other than that nothing exciting happened and team seven was on their way back to konoha. Upon arriving Kakashi sent Sasuke and Sakura away while he and Naruto reported to the hokage.
After the report given by Kakashi to say the hokage was shocked would be a understatement. He then said "I believe this happened due to young Sasuke's chakra activating the dormant Uchiha DNA in Naruto. This is due to he Uzumaki being related to the Senju who came from the sage of the six paths along with the Uchiha. In fact, it is rumoured the sage was a Uzumaki. Either way, they were slightly related and his chakra activated that." He then went on to explain Naruto's new responsibilities with this new tool for him to use and the abilities it granted.
After the meeting team seven were given time off meetings to train which Naruto was instructed to do chakra control along with Sakura while Sasuke went and did something with Kakashi. This happened for a week until Naruto decided to follow. What he saw upset him, Kakashi was teaching Sasuke jutsu! He decided they would both learn, he activated his sharingan and decided to only copy jutsu which seemed common as he did not like taking others work and it made him feel slightly better that way. After he copied two jutsu he ran out towards them while Kakashi was showing a third jutsu and yelled "I knew it! Your teaching him jutsu and not me or Sakura! Your a horrible sensei!" He then ran off leaving a shocked looking Sasuke and a guilty Kakashi.
Later that day Naruto got delivered a scroll, when he opened it he saw a note which read "You're right, I was a horrible sensei, please forgive me, I sent some chakra paper for you to test your affinity, if he paper burns you have fire, if it splits, wind, if it goes damp the it's water, if it wrinkles its lightning and finally if it crumbles that means earth. Good luck - Kakashi" he decided to give the paper a test, he pushed chakra into it and the paper split in half while one half wrinkled and the other stayed the same. This meant he had two affinities! He thought he was so awesome he went for celebratory ramen.
The next day went the exact same in training except Naruto decided to send some clones transformed as various ninja to read about element manipulation. He had learnt the clone secret by overhearing Kakashi explain it to Sasuke and said that he could use that if he got enough chakra, which Naruto already had. After learning what was needed, Naruto then ran off while leaving a clone to do the control exercise to pretend he was there. Once alone he made more clones to train his control and some to practise his nature training.
A week had passed and Naruto finally finished the leaf stage for both his elements, it took him three days for wind but didn't want it ahead of his lightning. He is now beginning the second stage of each element, slicing a rock for wind and lighting a lightbulb for lightning. He continued this for two weeks while simultaneously having even more clones training chakra control.
At this team meeting Kakashi did something unexpected, he called the team together together to explain how the team was being entered in the chunin exams and Naruto instantly knew he and Sakura were only there so Sasuke could go but he didn't mind, he wanted his chance to show his skill with the few jutsu he knew.
-Canon until first exam-
Once the first exam began, Sakura looked nervous, Sasuke smirked at how he could copy hand movements for answers and Naruto looked downright bored. After learning the shadow clone trick he had some clones read up on current important ninja and he knew the proctor, Ibiki Morino was playing a psychological game. He guessed it was the tenth question and decided to act then, until that he would just get the answers the same way as Sasuke.
When Ibiki asked who was going to leave Sakura was deciding to go for Naruto until both he and Sasuke glared at her to stop. A lot of teams left however and soon there were only 13 teams left. Soon after the second proctor arrived and informed everyone to go to the forest of death for the next portion of the exam.
After being explained the rules of the exam and having Naruto's blood licked by the second proctor, all the genin were running around the forest of death looking for scrolls . Soon enough Naruto's team encountered a hidden rain team who were using a tactic which involved reforming clones. They were soon dealt with as Sasuke and Naruto could see the real ones with their sharingan. Unfortunately they had the same scroll so team seven still needed one.
After searching for a team for a while team seven were beginning to give up hope for the day until a large of gust of wind came towards them. Luckily all three managed to remain rooted to the ground while a hidden grass kunoichi appeared and said "ku ku ku I see I need to fight all three of you for Sasuke-kun." The "fight" as the "kunoichi" called out to be "her" dominating them, they only got one hit in to reveal Orochimaru.
When Orochimaru noticed Naruto's sharingan and realised who he was, he couldn't resist giving his "gift" to him too so he could have a sharingan pawn eventually or see the effects of a bijuu with the mark. After giving both Naruto and Sasuke the curse mark he quickly fled leaving a scroll behind by "accident" to ensure they could make it through the exams so he could see what happened. No matter what did happen, it would be intriguing indeed.
AN: I am aware how bad this first chapter is with the lack of action and things, however I can promise there will be more in the next chapter. Although before that I need to know what you all think to these ideas:
1) Naruto has already unlocked he mangekyo sharingan due to seeing Sasuke's seemingly dead body and that is what first caused him to realise the pain in his eyes (In Tazuna's house) he will still be effected by the blindness and he will only know one skill for now (which I want to be included in the review of whether he should have it or not.) If this is chosen, the curse mark will be rendered useless by the kyuubi's chakra in Naruto. (Also describe what his MS should look like)
2) The kyuubi's chakra unlocks the second stage of the cursed seal for Naruto and destroys Orochimaru's consciousness from the seal so he has control of it (only to be used in extreme situations) If this is chosen, please give a description of what Naruto's stage 2 cursed seal should look like and if possible a picture.
3) Naruto has both of the previous ideas.
4) The seal is basically destroyed with kyuubi's chakra and he does not gain the MS yet.
The next chapter will show which option has been chosen. Until then, thanks for reading!
