What are you doing Naruto. Asked Itachi. How do you know my name. you know me as weasel. replied Itachi. These people attacked me so now I can't see out of my left eye. Well I will give you the eye of my friend that died. Said Itachi. He then planted the sharingan eye of Uchiha Shisui. Itachi left that night after he gave Naruto a note then knocked him out.
The next day at the hospital
Hello Naruto-kun. Said Sarutobi. Jiji! This note is for you Naruto-kun. Sarutobi placed down the next Naruto then left the room
Dear Naruto
This letter contains imformation you would want to know. You are the contaner of the kyuubi no kitsune that attacked six years ago. Your parents are Namikaze Minato and Uzumaki Kushina. The sharingan I gave you is no ordinary sharingan. It can turn into the mangeyko, it is really powerful. I gave you the knowledge of how to activate it. You can cast a genjutsu that can change the targets mind, i have made it so you can use it more than once a decade. The only problem is that your sharingan is always activated, to counter that keep your eye closed and covered. you don't have to worry about becoming blind because of the fox.
Sincerly Itachi
Naruto couldn't beleave it, so he deciced to sleep so he can take everything in that he just learned.
A day later
A lazy jounin walked into Narutos roon made a blood clone of Naruto then picked him up then left. Kakashi had a mission that mission was to train this boy for six years in the ninja arts, then take him back before the graduation exam. Kakashi had another plan, he would train him personaly for two years. His training would be in six deffrent parts. The first part would be pysical training, second taijutsu and fighting with one eye, third fighting with the sharingan during a fight, fourth is chakra control and elemental manipulation, fith will be learning ninjutsu and genjutsu and sixth will be polishing of everything he learned with some educational lessons. Naruto woke up and looked around. Who are you. I am going to be your sensei for two years, then you are going to your last living relative for four years of training. Replied Kakashi. Okay so when do we start. Asked Naruto. Now.
