Sage was born as a half human, half demon girl. Her half demon forms were that of the dragon demon and the fox demon. Her mother was half fox demon, half human, and her father was a full dragon demon. They abandoned her in the human world in a village of half human, half demon kin. She was abducted and taken to a scientific laboratory, where they conducted experiments on her, using her half demon DNA. The scientists altered her DNA to be more accepting of DNA from other races and demonic DNA. Sage has many forms, in addition to her first two forms, Yokomomo and Yukou.
