A renowned nanotechnology and biology researcher with an IQ over 200, Dr. Tearju is the source of Eve's DNA. Although she is the human Eve was cloned from, Tearju's eye color is green while Eve's is violet. (Source: Black Cat volume 12)

Anime:
She is shown in the final part of the story. She had amnesia and was forced to wake when Sven and Rinslet showed her a picture of Eve. Her eyes are also the same color as Eve's (violet) instead of being green like in the manga. She also doesn't show any of her trademark characteristics (bad cooking and clumsiness), as she appears right in the final part of the plot.
