Takeshi is a 16‑year‑old boy who has just formed an American football team at the BlueSky orphanage. While playing a game, a sudden light appears in the sky, interrupting the match. Through the event, Takeshi learns that he is the son of the king of the planet Apolon. He was brought to Earth by his father’s retainer, Rabi, to escape death at the hands of General Dazaan. Possessing special energy abilities, Takeshi can control UFO saucers that emerge from beneath the ocean floor; these saucers can transform into robots that move in sync with his commands.
