I remember when I was a kid watching and reading Naruto around the chunin exam arc I got so obsessed with Anko. If you don't remember her, Anko was one of the instructors of the chunin exams, specifically the second part of the exam in the Forest of Death.
Anko had also previously been on a team led by Orochimaru when she was a genin. She was the first person to survive the cursed seal of the heavens, and still bears it.
Anko didn't get a tremendous amount of time around, but while she was in the spotlight she did do some awesome stuff. She proved that she was a force to reckoned with. She showed a steely resolve in a short time.
She demonstrated love for her village in her readiness to take on Orochimaru and Kabuto and the rest of the sound ninjas who attacked the exams. She leapt to the defense of the genin going through the exams without hesitation.
Not to mention, she's a total babe.
So much love for Anko. I hear she's even playable in Naruto Ultimate Ninja Storm 4.
