Trivia

 * This particular kunoichi bears numerous stark similarities in appearance to another unnamed character associated with the usage of Hiruko's Chimera Technique, during Naruto Shippūden 3: Inheritors of the Will of Fire. It is believed she comes from Sunagakure seeing that the other shinobi homelands are pretty noticable.
