Yang and Yin Apart (Naruto x Reader x Sasuke)(On Hold)

(F/N) (L/N) was just born, and was captured by the Akatsuki. She is the sister to Gaara, but his demon is the Yin, while her's is the Yang. Gaara knew he had a sister, but thought she was dead, and didn't know she had the other side of Shukaku, the demon. (F/N) knew she had a brother, thanks to her side of the demon, who was like a father to (F/N) she'd never had. She called him 'Father' or, 'Yang', and he's just call her 'Pup'. She'd thought of the Akatsuki as her new family, but still wished she had her brother there, but knew she was being used for a weapon in the akatsuki, so she trained in secret.
