White Tiger of the Hidden Leaf

Caty Taiiji is a respected ninja in the Leaf Village after being brought there by her older brother Lash when they were both young. She quickly becomes friends with everyone, but what happens once the Akatsuki and Orochimaru decide to show up again? And what happens when a certain ninja catches her eye? No idea on pairings but I am open to suggestions. BASED IN SHIPPUDEN
