The only thing standing between the Earthlings and annihilation is the transforming, karate-using super robot, Daimos, and its pilot, Kazuya Ryuuzaki. But that changes when he meets and falls in love with a mysterious girl named Erika, who turns out to be Richter's sister. Over the course of their struggles to reunite, Kazuya and Erika each learn that the other's people are not all evil... and that their own people are not all good. (Source: AniDB)
