She is a Cosmic Wraith of the fighting race, and is a cool sadistic older sister. Perhaps because she has only ever fought, she lacks a sense of purpose and often speaks in a bluntly. She enjoys teasing the protagonist, calling him "master" just to see his reaction.

To her, a human male is someone she must subjugate. During mating, she tends to uses six cords to find out what kind of pleasure the male is getting and how he is responding.
The cords can be used in a variety of ways, including squeezing, heating, rubbing, and electrical stimulation.

The cords allow her and her mate to share sensations. The pleasures of a male and female orgasm at the same time is said to be indescribable.
