Assassin of the Shadows (Gaara x OC Fanfict)

Teiko Uzumaki. Yes I am Naruto Uzumaki's sister. We are even twins, but unlike Naruto, instead of having the nine-tailed fox, I have the seven-tailed wolf. I am Naruto's younger sister by, well I don't know how long. Although I had no clue I was related to anyone until I stumbled upon the Hidden Leaf Village. I was one of Orachimaru's experiments, somehow I escaped.

Well, read on to find out more ;P
(Warning: I will improvise a lot of parts because it is hard doing everything word for word <3)
