Mitsuki Rara is Mitsuki Sanada’s counterpart in the parallel world. They look exactly alike except for the color and style of their hair. However, the similarity ends there. While Mitsuki Sanada is cold and abrasive, Mitsuki Rara is gentle and friendly. She is well-liked by her peers and subordinates. Her parents are Hiroshi and Ayuko Rara, the leaders for the Rara Army, enemy of the Earth Defense Force. She is usually a shy and quiet person, however, when she becomes her alter ego, Miss Ra, who is the field commander for the Rara Army, in order to be helpful in the war effort, she'd place herself into a trance to play the ruthless warrior.
Mitsuki Rara once personally nursed Kazuki Yotsuga back to health after he'd been injured while fighting one of the Rara Army's robots. However, when she finds out that Kazuki is an enemy pilot, she launches him away in an escape pod, remembering the time he could have killed Miss Ra, but saved her instead.
Mitsuki is later brainwashed by her mother into piloting Himiko, one of the most powerful robots created. After Kazuki saves her, she resists returning home, eventually becoming a Core Robot pilot for the EDF. She comes the closest to capturing Kazuki's heart; the two almost go out on a date, which is unfortunately cancelled by U.N. officers intent on sending her home.
When Zinv is destroyed and the worlds merge upon Kazuki's wish, Mitsuki lives in the Sanada home with Kazuki and the other girls, even though her parents live right next door. At the end of the series, she decides to go into space with everyone.
