Kayra is a MS pilot in the Earth Federation Forces, a lieutenant in rank and the commander of the Jegan unit. She was the spearhead of the Mobile Suit Squadron under Amuro's command. She is a woman who possesses both bravery and kindness in battle, and she and Astonaige Medoz, the chief mechanic, were lovers. She had been piloting a RGM-89 Jegan, but after Amuro boarded the RX-93 ν Gundam, she took over the RGZ-91 Re-GZ.
During the battle, she is attacked by Gyunei's Jagd Doga and others, and is thrown out of the Re-GZ and captured by the Jagd Doga, becoming a hostage. Gyunei pressures Amuro to hand over the ν Gundam to him, and Amuro relinquishes his rifle and fin funnels, but when he is attacked, his fin funnel, which was not adjusted properly, reacts more sensitively than he intended, and it fires a defensive shot. Gyunei, enraged by this, crushes Kayra and kills her in cold blood. She was unable to fulfill the promise she had made to Astonaige to eat a salad together before her sortie.
