Anko Mitarashi is a shinobi of the Hidden Leaf Village and she was one of the examiners for the Chunin Exams.
Anko was once a pupil of Orochimaru and like Sasuke Uchiha was branded with Orochimaru's cursed seal.
Anko is tomboyish, fairly easy going, sometimes hyperactive but also intelligent. She also seems to have picked up some habits from her time with Orochimaru as a child, such as using her tongue to lick her kunai or lips before fighting and having a bloodthirsty appetite.
In the English dub version of the Naruto anime series by VIZ Media, Anko Mitarashi was originally voiced by Julianne Buescher. Julianne Buescher voiced the character in the Chunin Exams through the Konoha Invasion arcs.
In the video game Naruto: Ultimate Ninja 3, Anko Mitarashi was voiced by Kari Wahlgren.
Anko made some future appearances in the Naruto anime series but mostly in filler episodes not officially related to the main story-lines in the manga by Masashi Kishimoto.
In the Land of the Sea filler arc and onwards (including the sequel series Naruto: Shippuden) Anko was voiced by Laura Bailey.
