Grae is often recognized for being the possessor of the spheres of the future. She is someone of few words, but she doesn't hesitate to express how much she likes anime and manga. She loves listening to music, because she feels that to the rhythm of music, the things she does on a daily basis are more fun and interesting.
When Grae was just 12 years old, on a normal day she was walking near her house, but then she saw a meteor crash into her garage. As she got closer, the meteorite opened up, showing her 7 spheres. Over time, Grae discovered that those spheres could show her the future, so she used them to earn money by reading people's future fortunes, and she soon became very famous. When her fame spread, she made a mask with her own hands in order to hide her identity and keep her personal life quiet.
