Kakashi has a daughter. A mischievous one, like her mother. Her name is Katsuei Uchiha Hatake. Her mother was, of course, an Uchiha. She died during the Nine-Tails attack, but wasn't killed by the Nine-Tails himself, but, by the hand of a certain masked man.
Kakashi raised the little girl on his own, with the help of his friends. She grew up to be very strong, with the help of her Sensei's, one of them was Tsunade.
Only a few people knew that she had the Uchiha blood in her, some of them were the Three Legendary Sannin, including Orochimaru.
What are his plans? And how will Sasuke and Itachi react? What will the Akatsuki do? What will Katsuei do, after figuring out that she's being targeted by more than one person? And what will Kakashi do?
(I do not own the characters except for my OC, nor do I own the pictures, unless I say so. Just to warn you there will be cursing/swearing/cussing)
