Natsuko Uzumaki is Naruto's twin sister. Natsuko isn't the type of girl to be pushed around. She has a crazy behavior just like Naruto and her feisty personality seems to have caught the eye of a certain Uchiha. I DO NOT OWN NARUTO OR ANY OF ITS CHARACTERS! NARUTO BELONGS TO MASAHI KISHIMOTO. I ONLY OWN MY OC NATSUKO.
