Uchiha Rin is Sasuke's younger twin. She has piercing blue, rare eyes. She looks alot like Itachi. None of her family members like her. Well except Itachi and Shisui. They never hide anything from each other. They love each other. The young Uchiha has her cousins wrapped around her little finger, but they don't show it. They can't show it. Not in fear of what may happen to their families.
