Myra is the mother of Üso Ewin. She left him just like his father leaving them at Kasarelia after giving him the abilities to grow personally, believing that Üso will have to fight in his own in the future. She participated in the League Militaire by putting her talent to design the LM312V04 Victory Gundam, and later the LM314V21 Victory 2 Gundam. Üso found her when they make a stop at the city of Saint Joseph on the Moon. But their reunion was short-lived, because she was quickly captured by the Motorad fleet of Zanscare, which was heading for the Earth.
Carried out as a prisoner on Earth by the Motorad fleet, She was found by Üso when they develop their Shahkti rescue plan. Having to deal with both, Myra eventually let them go. Subsequently, Arbeo Pippiniden used her in a strategy to prevent Üso from beating him by using a mobile suit with Myra as a hostage, bound to the suit itself. While Üso managed to immobilize the Mobile Suit, she was killed in front of her son by a collision with another Motorad unit just before the ceasefire and Zanscare's temporary surrender. She was decapitated, Üso retrieves her helmet with her head still inside, giving it to Marbet Fingerhat and then crying with the younger members of the League Militaire.
