Mia Alice, Roll Kran, Lamba Nom, and Pai Thunder are four teenagers brainwashed and reconditioned as ESPers by Dr. Tarsan, who intends to sell their services to the Bunker Space Pirates. The quartet, however, escapes from Dr. Tarsan's ship, infuriating Bunker leader Captain Galimos. Gil Berg, Dr. Tarsan's cyborg assistant, offers his services to Galimos to capture the teenagers. He heads to Earth to lure the teenagers, as Mia is originally from the planet. Following an encounter with two of Dr. Tarsan's other creations, Pai regains her memories and heads to the Bunker's capital ship, taking an unconscious Roll with her. She reveals herself to Galimos as her daughter Barius, but she quickly renounces her birthright before rejoining her teammates and head to Earth with Dr. Tarsan, who also develops a change of heart. Upon their arrival to Tokyo, the teenagers combine their Dan-Mechanics to form Dangaioh and defeat Gil. They offer to spare his life, but he chooses to go down with his destroyed mecha instead. Despite returning to Earth, Mia chooses to stay with the team, as she has no memories of her past life.
