Biography
Nena Hagen is a test-tube baby like Rudolf, though it is unknown whether she is Rudolf's blood sister. She respects and loves Rudolf dearly and dislikes Aika for “seducing” him. Nena has a sadistic nature and unstable mood, and punishes black Delmos for failure.
Story spoilers
Rudolf later gives Nena an Alternate Metal device that powers her up, but it fuses with her and runs out of control. She transforms into a monster, kills Rudolf while embracing him, and flees into space carrying his body; her ultimate fate is unknown.
