It is time for review(s):
lunatic meap - Glad you like the concept however you did get your terminology wrong, the correct term is OOC (Out-of-Character) rather than SI (Self Insert) and remember, this is told from the perspective of the characters when they are older and the Naruto in this story has memories of everything since birth so I would imagine that his mind would be warped from this, this is why Naruto is way he is in this story.
One other thing, many things are different in this story, like events that happen in this never happened in canon and vice versa. So please don't say anything like, "So and so never happened in the anime, so this story sucks", I haven't had any of those yet though I know I will. (Though you can ask why I changed that particular event)
I have memories of a broken and shattered future, one that should never happen under any circumstance, this future would mentally traumatise anyone but has it put me down? No, not in the slightest.
Normally, an Uchiha would regard as anyone not from the Uchiha Clan, that was not a Kage, below them and while I had to act like that for a while, it was really grating to do do. The timeline that I somehow have memories of is one of destruction, anarchy, war, megalomaniacs and colossal battles between hugely powerful shinobi including himself, the person that was considered a vile creature simply because of a burden that he could not get rid of and the girl that I considered the most grating of fangirls during my academy years.
Obviously, I could not allow this 'future' to happen. So I trained, I trained from the age of 5, starting with the very basics of shurikenjutsu and taijutsu. My brother was a prodigy of, well, everything that he ever tried quickly noticed this and took the opportunity to train me in the arts that I was practicing, he was the first to notice that I had above average skill in these arts and started to work me into the ground so that I would be strong, my mother then noticed this and took her own initiative and train me in what she did during her tenure as a shinobi. She was often in the ambush teams and as such she could hide her chakra signature to anyone that was not a Hyuga. She was also a taijutsu and shurikenjutsu specialist, moving in a quick and efficient way that the enemy wouldn't even realise that they had been attacked.
My father, Fugaku, however would not train me, he thought that it was not worth it if both Itachi and my mother, Mikoto, had to train me in the shinobi arts and just generally things concerning shinobi. They created a timetable of learning, something I used for a long time, even after the Uchiha Massacre where Itachi killed conspirators of a coup d'tat including our father, if it was on the orders of Hokage, I had no idea at the time but it seemed like it. He did not kill our mother as she had very little, if anything, to with the coup, unlike the every other adult in the clan minus one. He also did not kill the children of the clan and his only possible equal, Shisui.
After Itachi fled and with all the other adults dead minus Mikoto, Shisui took it upon himself to become the clan head. Who else was going to do it if my mother refused the role, me?, I was way too young, untrained and inexperienced to fulfill that role, Shisui was in his twenties.
After I entered Academy, the most accursed demons came upon me, not literally at that point though I'd imagine some did on posters and pictures of me in later life. These demons were known as fangirls and they would till your bones wasted away. They were loud, violent and overly passionate about me, not really what looked for in someone. There was only one girl in our class that was not like this and it was obvious that she had a crush on someone else, she was shy anyway.
In the academy I had to act like the biggest dickhead in the entire world. It was not fun in any way, shape or form, even though it could seem like it to any incredibly bored person. That put me at odds with the apparent class clown and loudmouth, Naruto Uzumaki and just about any other male in my class as they wanted to take me down from my supposed high pedestal and possibly take the proverbial throne for themselves. My fangirls were too infatuated with me too realise unless it actively got in the way of their fawning.
The Graduation Exam was the most overrated thing you could imagine. It was supposed to be the hardest thing in the world during our time in the Academy, an overhyped piece of bullshit that we were absolutely terrified of for no apparent reason. It wasn't that hard and I knew even back then that it was because of two reasons: Konoha was not at war with anyone so nobody had to be rushed through the exam system to bolster the military's numbers and because civilian families on the council wanted their child to have a higher chance of becoming a shinobi just so their family could have a little bit of prestige. I can tell you now from that I later found out that there was hardly anything about being a shinobi, I was even skeptical of it even back then. Anyway, I passed with full marks everything making me the 'Rookie-of-the-Year' which was meaningless on the field.
The day off we got between the day we graduated and the day that we would be put into teams was one of great anticipation for me. It was impossible to not think about it, which almost made me slip up in a spar that one of the of children of the Uchiha Clan had challenged me to, it would have been incredibly embarrassing if had lost to that Kid, an 11-year old boy named Yubi, which would make him able to boast that he beat me and that would not look good on my resume.
The day came and went and the nest day emerged from the dark night. This was the day that the teams would be announced and my word, is that important day in the average shinobi's life. Not only do you meet the people who are likely to be your best friends for the rest of your life but you also get a potential elder brother/sister relationship or a mother/father with your sensei as some of what you experience when youy walk the path of the shinobi will bond you in way that you never thought would happen.
I woke up early and decided to take it slow to the Academy so that I would be too early that even Iruka had not arrived. Speaking of which, Iruka as looking slightly sad and Mizuki was not with him, at the time I had no idea where Mizuki was and why he was not here. It was only during my time as a genin that I would learn that Mizuki was a criminal in the eyes of the village.
"Alright, settle down people, settle down!", Iruka shouted, it was obvious to me that he was not in the mood for nonsense today, not any more than what he usually puts up with, at least, "Alright here are the teams, Team 1...", I wasn't really listening until my name came up, "Team 7: Naruto Uzumaki, Sakura Haruno and Sasuke Uchiha under Jonin Kakashi Hatake".
I pretended to be angry, I had to. Otherwise it would break the illusion that everyone had perceived was me. Inside, however, I was happy as I knew from the memories of the broken world that they were than they showed to be here and I knew of the name Kakashi Hatake, from him being the only person outside the Uchiha Clan to have a sharingan, though his was implanted into his left eye from his dying teammate.
My teammates had very similar visual reaction, though for different reasons as I would later find out.
Here you go, have Sasuke's chapter.
I think this works and that his personality is different from Naruto in this story and I know that he different from the canon Sasuke.
As usual, please feel free to ask questions, give suggestions and just general constructive criticism. It helps me make the story more enjoyable.
Sincerely, your friend, DaPika.
