A lilac-haired girl from the Oracle Think Tanks, not much is known about her past other than something that affected her mentally. She was found by one of the members of the Oracle Think Tank, who brought her to CEO Amaterasu after glancing into her future. After learning about what she would do in the future, Amaterasu tried her best to keep Misaka's thoughts away from her past. Anyone who were curious would eventually realise that it was better not to know.
She bears a striking resemblance to Tokura Misaki on Earth, to the point where Misaki would start recalling her horrid past.
