Sorae Igarashi

Sorae Igarashi is Ganta Igarashi's mother. She is a doctor who was involved in the development of the Wretched Egg and the Mother Goose System. She is probably dead, but there are still mysteries how she died.

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. For unknown reasons, their research gave birth to the Wretched Egg. During the Great Tokyo Earthquake, the medical center was destroyed and Sorae was supposedly killed.
