Goodbye and Hello

A young girls world, crashes down on her in a blink of an eye. She becomes emotionless, and cold blooded. She trained for one specific reason. So she can be strong enough to kill whomever killed her family and maybe, but most likely her friends. Then while she was doing what she normally does after a hard day of training and killing... She ends up in another dimension?!? Will she ever get her revenge? Or did an opportunity arise she can't back down from?

While her life goes haywire, she starts remembering her strange dreams, before Naruto, that involve Kakashi?!?
