Prologue:
In an alternate reality, Itachi is a Jonin who lives in Konohagure. He is known to have sacrificed his entire clan in order to prevent their coup and the resultant Great Ninja war from taking place. Being an Uchiha who overcame the curse of hatred and lives with the will of fire, he is seen as the future hokage of Konoha.
Unknown to most people, he is rarely send on any missions as the use of Mangekyo Sharingan is detrimental to his eye sight and health. As he has many enemies, nobody in the village usually knows his whereabouts apart from the Hokage.
There were plans on declaring him a criminal and sending him to spy on the Akatsuki, but it was deemed too dangerous by the third Hokage, who saw it as a further injustice to Uchiha clan, which shouldn't be allow to end with Itachi.
Nowadays, Itachi usually spends most of his time training the Genins of the village, teaching them about the will of fire and helping them find their way of life. He also spends time researching old and lost Jutsus, while also inventing and teaching them.
He is a pacifist who is somewhat anti-social and focuses more on training himself and others than enjoying his youth.
He was the one who fended off Orochimaru when the later betrayed Konoha. Before the third Hokage died of old age, he entrusted Itachi with the mission of taking care of the 9 tails Jinchuriki when Jiraiya isn't around and of restoring his clan.
Itachi is also by default the patron and head of Konoha's police force.
A/N: Prologue's up. I'd increase it's size after I upload the first chapter(The story begins from the next chapter). If you'd like to beta read this story, send me a pm. If you'd like to help me out, please write what would've happened if Itachi didn't had a sibling, along with the reviews. Also, let me know of things I've missed out that I should've included in the prologue.
"Mata kondo da"!
