A saucer-shaped spaceship approaches Earth, and heads for Tokyo. It lands on a forested hill not very far from the city. But it is discovered lying harmlessly awkward.

Tokyo's night sky is hit with flood of headlights flowing through the veins of elevated speedways. But below, the ground is dark and gloomy.

U7, member of Japan Branch of Unicorn, is the one who controls the gigantic GIANT ROBO with the wrist-watch controller microphone. One day, he receives from his father a parcel as a birthday gift. It is a kit for constructing a man-size robot.

U13, member of the Japan Branch of Unicorn, is on night patrol. At the entrance of a town he picks up a girl who is half frantic with fright. The girl explains that all the people of the town are dead. So it is. The street is littered with corpses.

Tokyo and the entire Earth is lying in peace. But there is deep in the hearts of the people a faint foreboding that something terrible might happen.
