She is 18 years old and 156 cm tall.
It is later revealed that she is actually Roy's daughter Rita Revant. Her hair and eye colour had changed due to exposure to nanomachines from the Blast Fall. Having been adopted by Larry and Andy's father with no memory of who she was, she initially resisted the idea that she was Roy's daughter until later. She was supposedly killed in the collapse of a clock tower, but later, she was shown to be alive and working for Ashley Lynx in order to follow their common dream of equality among residents. She was given a red and black Proceed suit. It also includes a jet pack, which allows her to fly. Solty eventually wore the suit in the final episode when she went into space. Eventually, she overcame Ashley's brainwashing to see the limitations and problems of her attitudes and dream.
