Aiden does have a good point.  She could be descended from her.  Other options include:<br/>1).  Having a Sword from the Seven Swords of the Mist.<br/>2).  Lava (which is Earth and Fire Chakra)/Water Ninjutsu<br/>3).  Uses Chakra blades (think like the Samurai and their swords able to become stronger like that)<br/><br/>Those are just to start.  She could specialize in summoning a certain type of animal as well.
