Erica Wald

Erica Wald is a surviving Künstler and member of the Einherjar, making her a necro soldier. She was Yoko's closest friend during the Terraforming Wars, during which both girls were orphaned and were subsequently taken into Grünthal. Erica surfaced during Operation Hagel as the mysterious Frau X (フラウ・X) (German for "Woman X", equivalent of Jane Doe). Her true identity was strongly hinted at, but not definitively confirmed until the events of Mars Chronicle. As a child, Erica was initially kind and friendly, particularly towards Yoko. After remembering how she had been abused by and killed her parents, Erica's suppressed dark side was awakened and cultivated by Baron Muster, turning her into a cruel and sadistic person. After being trained by Grünthal, she became an embodiment of the Künstler fighting ethic in its prime, that of a ruthless and brutally efficient warrior. Although she displayed a grudging respect for Zazie during their fight, it was speculated that she used an unnamed Dim Mak-like technique on her in order to try and break her spirit for displaying such determination. She has a tendency to use German words in her speech.
