Naori Uchiha was a kunoichi from Konohagakure's famed Uchiha clan. Her close friend Naka Uchiha was able to use Izanagi and in time, became obsessed with its power. She was determined to save him from it and so ultimately cast Izanami on him in order to get him to see the error of his ways and come to accept fate. She was successful in this and Naka was able to finally accept the truth and break the endless loop the technique had plunged him into. She presumably died either before, or during the Uchiha Clan Downfall along with the rest of her clansmen.
