series, Kazuki subconsciously awakens one of the original alien mechas, a robot named Zinv. It is revealed that Zinv is Kazuki's counterpart in the parallel world. When Zinv is destroyed, Kazuki's desire for the group to stay together results in the creation of a third possible world, where elements from the parallel universes are combined. Mitsuki is the most admired girl in Kazuki's school; young men constantly send her gifts and cards, and Kazuki is nearly lynched for speaking to her. She lures Kazuki to her house for her father's experiments, and later follows him into the parallel world (for some reason arriving a month before he does). She is the daughter of both Ken Sanada and Ayuko Sanada in this world; however, she is in no way related to the Ken Sanada from the parallel world. Mitsuki is also an exceptional robot pilot, and joins the EDF to end the war, hoping research to send her home can begin afterwards. Unfortunately, Mitsuki is hotheaded and easily manipulated, and is captured by the Rara Army towards the end of the series and coerced into piloting the complete version of HIMC. She clearly has an attraction to Kazuki, but covers it up by treating him abrasively. When Kazuki is lost behind enemy lines, Mitsuki is affected most of all. D is a bioroid, an artificially constructed biological/mechanical being first introduced in the Tenchi Muyo! universe. The war between the Earth Defense Force and the Rara Army began when D and at least two mechas were discovered in an artifact of unknown origin. Her original body was damaged, so a bioroid was built to contain her essence (represented by a glowing orb in place of an eye) while her body healed. D appears to be as inhuman as the robot she pilots, speaking mechanically and asking many questions about human emotions and behavior. The only one to break through her stony exterior is Kazuki, to the shock of Commander Sanada and Mitsuki. D frequently has visions of a horrible creature attacking, and is deathly afraid of HIMC. She develops a strong attachment to Kazuki, culminating in her decision to return to her real body at the climax of the series in order to save him, at which she came to the realization that she was in love with Kazuki, a new feeling she had not experienced or understood before. It is then
