Naruto: Clash of Ninja/Anko Mitarashi

Anko Mitarashi is a proctor for the Chuunin Selection Exams and was trained by criminal Orochimaru at a young age. Orochimaru branded her and nine others with his first ten samples of the Cursed Seal of Heaven, and she was the only one to survive, rendering the survival rate of the curse as one out of ten. He then supposedly rejected her as a subordinate since she didn't have a lust for power like he did, and Anko was taken in by the village of Konoha. She is similar to Naruto Uzumaki in many ways (stubborn, easygoing, and hyperactive) but is also studious, unlike the young ninja.
