Historia Reiss or Krista Lenz as the series would later cover why some of us give her two names-- is one of my 3 favorite characters from the well known series "Shingeki No Kyojin" or loosely translated "Attack on Titan". It's basically about an old world where Titans (Huge genderless giants) who are by far immortal, feed on humans which are about the size of the palm of their hands.
In comparison to my two other favorites, she's quiet and very gentle. Rivai and Mikasa aren't generally very graceful in terms of dealing with other people. So by far she's the sweetest character there. And although she's like that? She's also strong to some extent. She's not your average damsel in distress.
