The story is about 16 years old boy Takeshi who recently formed an American football team at the BlueSky orphanage. One day the game is interuppted by a light in the sky. Takeshi discovers he is the son of the king of the planet Apolon, spirited away to Earth by his father's retainer Rabi to avoid death at the hands of General Dazaan. He turns out to have special energy abilities which can control UFO saucers from under the ocean floor, which in turn can become robots that are synchronized to their movements.

Five episodes were combined and dubbed in English to create a re-edited movie called Shadow World.
