Ringo is a robotic young girl cared for by Ouji.
Ringo is a sweet little girl who loves flowers and her friend Casshern. She is very innocent and often does not get or want to understand how horrible the ruined world is. Many simple things are new to her, such as ladybugs and glass bottles. Casshern has a soft spot for her, and saving her was the first time he had done something to aid someone rather than destroy them. Lyuze, Friender, and Ohji also care for her very much.
She was found as baby lying in a ruined robot body (who may have been her parent) by Ohji, who was extremely suprised that innocent life could thrive in such a decaying world. She has become his reason for living since then, and the thing he wants most is for her to be safe and happy.
