ネーナ・ハーゲン

She is a test tube baby like Rudolf. It is unknown if she is the blood sister of Rudolf. Nevertheless she respects and loves Rudolf dearly to a level beyond siblings, and dislikes Aika for "seducing" her brother Rudolf. A sadistic character and unstable mood, she walks around in her bare essentials and makes sure the black Delmos are punished for failure. (Source: Wikipedia)
