Jill Ratokie is the brother of Miharu Ratokie and Milly Ratokie. Some years after Miharu's death and the end of The One Year War he joins the Titan's Cyber-Newtype Murasame program (along with Four Murasame) but is killed as his body is unable to cope with the tremendous mental energy overload of the Psycommu system onboard the Psycho Gundam.
