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.

She later receives from Rudolf an Alternate Metal panty which allows her to transform to a powered up form. However, the device fusing into her soon runs out of control, and she becomes a hideous monster. In this form she embraces and kills her brother and flees into space cradling his corpse. Her ultimate fate is unknown.
