Fighting General Daimos - S01

The third of Tadao Nagahama's Romance Super Robot Trilogy. (#1: Chou Denji Robo Combattler V, #2: Chou Denji Machine Voltes V) After their home world is destroyed, the survivors of the planet Barm set out for Earth, hoping to negotiate the purchase of land to emigrate to. But during the negotiations, the Barmian leader, Leon, is assassinated by his second in command, Olban, and the Earth delegation is framed for the murder. In the chaos that follows, Doctor Isamu Ryuuzaki of the Earth delegation is shot and killed. Soon after the talks end in disaster, the Barmians (called "Valerians" in Starbirds) launch a campaign of terror against Earth, led by Leon's son, Admiral Richter, who sends a variety of "Mecha Soldiers" against the planet's defenses. 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.
