Blue And Pink (Kankuro?)

Rei Tanabe is Sakura's cousin but despite being related, they couldn't be more different.

When Rei first comes from the Sand Village to live with Sakura and her parents, the two girls get along and Rei was always willing to stick up for Sakura when people bullied her. When Sakura befriends Ino, both Rei and Sakura begin to change as they grow older and soon come to dislike eachother.

When disaster strikes and her old friends from the village hidden in the sand attack during the chunin exams, she must make the decision. Her new village or her old one?
