Guren

A kunoichi who appears in the second Naruto Shippuden filler arc. She is the female leader of Orochimaru's subordinates. She uses the unique Crystal Release brand of jutsu.

As a child, Guren came from an unknown small village where she was shunned by others because she had unique powers. Later, Orochimaru appeared and destroyed the entire village single-handedly. He was intrigued by Guren's powers and offered for her to come with him. Guren chose to follow him because she envied his power. Quickly, she became one of Orochimaru's most powerful and loyal subordinates. Eventually, she was offered to become one of Orochimaru's future vessels.
