Hagen, Neena

ネーナ・ハーゲン

She is a test-tube baby, just like Rudolf. It remains unclear whether she is Rudolf's blood sister. Regardless, she respects and loves him deeply, to a degree that surpasses typical sibling bonds, and she dislikes Aika for "seducing" her brother Rudolf. A sadistic character with an unstable mood, she walks around in her bare essentials and ensures that the black Delmos are punished for any failure.
