Myeong Ja is the mother of both fashion designer Yun-su and Prism Star Chae Kyoung. A former actress and Prism Star herself, she used to be lovers with Kintaro Asechi, Kyoko Asechi's father and Kei's first husband. However, she was unable to live up the designers expectations in the Prism Show world, no matter how she tried. During this time, Kintaro caught a glimpse of Kei and her Prism Shows, and decided to focus on making her a Prism Star instead. Although not formally breaking up with her, Myeong Ja could not take his obsession with Kei and her skill any longer, and left him in tears. She still holds a Prism Stone he designed, though it is empty. She is married to an unnamed husband, and only appeared in flashbacks in the Dear My Future anime until Yun-su and Shou went to her to ask about the secrets of the birth of the Symphonia series. She has aged quite a bit by this time.
