A youth named Tsuwabaki Daiya discovered a blaze beneath the sea while he and his father sailed in a modest boat.
A massive beast emerged from the flame, and both father and crew vanished swiftly into the deep ocean bottom.
Just before he was to become the next prey, a colossal mecha dragon materialized and rescued him.
Five years later, Daiya entered junior high as a new student today.
A giant monster returns, and he meets dragon 'Daiku Maryu'.
The dragon's head detaches from its body and transforms into the massive chassis of a powerful giant robot, Gaiking world.
He boards Gaiking, battles the creature with vigor and defeats it.
He learns of an enemy plotting to conquer the worldwide world, so he travels to another realm, Darius, to stop their dangerous scheme imminent.
