Silvia

The Chief Machinist of Rheinmetall AG. She was highly skilled despite her age and betted with Xia Lei that she could refine more precise parts than him, only to be defeated and losing the bet, resulting in her needing to give her body to Xia Lei, which he refuses. She, however, uses this as an excuse to lure Xia Lei to her home where she tries to drug him, only to be drugged herself. It is revealed that her lover who works for AE was using her to try and get Xia Lei's body.
