In her Krista persona, Historia is usually very shy, kind, and uncertain on how to interact with others (likely due to her isolation as a child). However, Ymir notes that Historia's urge to show kindness to others stems not only from a desire to gain their esteem, but also that of the people around her: to be seen as a good person. This likely stems from her having been denied the esteem of others as a child and being raised to believe that she was an unfortunate mistake.
