Who is Anna Liebert?

Johan's twin sister and the only unharmed survivor of the night when both her parents and her brother were shot in what appeared to be a botched burglary. At first she showed signs of amnesia due to the psychological trauma of the incident. After she and her brother disappeared, she was adopted by the Fortner family from Heidelberg, who were unaware of her previous identity as Anna Liebert.

As Nina Fortner, she was a hardworking law student at an unnamed university (likely the University of Heidelberg), as well as an adept practitioner of Aikido. She lived her life in peace until Johan made contact with her on her twentieth birthday. She comes to pursue Johan, albeit by different methods and for a different reason than Tenma.
