The Forgotten (Sasuke) 《COMING SOON》
"I am forgotten, lost to time."
What if there was someone else like Itachi? Given, she was a lot younger, but still forced to kill her clan. Under the direct orders of the Kuraikage, she moves to Konoha, where she is promoted to ANBU Black Op. Eventually, the Lord Third decides that she should be given a childhood, and places her on, you guessed it, Team Seven.
"My only wish is for death, but I cannot go yet. You see, I have exactly how I want to die planned out in my head to the smallest detail. I know who is going to kill me, what should be the last blow, how I would love the feel of my own blood cascading down my skin. Now, I hope you see that I don't want any connections to anybody."
