Appearance
Sorae has long black hair that is kept in a braid over her right shoulder. She wears regular clothes; a green sweater and light pants. Over her clothes she wears a white lab coat. She is always seen walking with sandals on.

Personality
Sorea seemed to be a loving and caring mother to Ganta, and mostly to Shiro, treating her almost like her own daughter. She is seen crying to herself many times through out her time experimenting on Shiro, most notably when she plays the lullaby.

History
Ten years ago, Sorae lived and worked as a professor at the Medical Center together with Ganta. She and her team conducted research to heighten a human's immune abilities. Their "guinea pig" for this research was Shiro. Due to the inhumane and brutal experiments preformed on Shiro her mind developed a second personality to deal with the pain, their research gave birth to the Wretched Egg.

Plot
Sorae was a scientist working with Hagire and when they came upon Shiro (A.K.A the Wretched Egg) Hagire became sickly interested in Shiro and preformed gruesome "experiments" on her when Shiro couldn't handle the pain and formed another personality. At the time Sorae was completely destroyed knowing what she had done to Shiro. She often cried and played her piano singing different versions of the Lullaby. When The Wretched Egg could no longer bear the pain and caused the great earthquake she sent Ganta away to his father saying " I can't run away... That child... I can't leave Shiro like that." Ganta removing Shiro from his memories questions who is that and she tells him to take care. For the time being that is the last time we ever heard of Sorae.
