Yes, she is. Its confirmed in Dark Fate initially, but expanded more on Lost Eden. And its a good thing you linked one of the translations (which happens to be done by a friend of mine, too) because she played the game.

Karlheinz only went after her because of her half-First Blood heritage, so he can produce a child with her. He doesn't really feel any love towards her. At the time of Karlheinz's reign the only First Blood female left is Cordelia; even as a half she still has it, and Karl took that to his advantage.
