Anna is a former fellow Keaton student and they both have something in common. They both share an interest in archeology, which is why she likes to stay in old ruins and look for artifacts from days gone by. Although she used to be a very popular girl with the other boys, she was never really interested in the other students, only the best would have been good enough for her, but he showed no interest in her, which is why she is always interested in her work and devoted to studying. Even then she was a very ambitious woman who was one of the most talented and inquisitive students. She has not necessarily chosen a job that is typical for a woman, but she is strong-willed and assertive, and she always works with passion, which is why no work is too difficult for her.
