The Getta team is engaged in a tremendous fight with a robot Demon while the carpet bombed Saotomè laboratory is razed to the ground: with the defensive defeated, the Demons are preparing to attack Tokyo. The 3 shuttles are buried by a mass of rocks and when they manage to free themselves, we notice Hayato, seriously injured in the leg. Back at the laboratory, the boys find the occupants in precarious conditions and little Genki is unconscious. The professor, in light of the situation, shows the three pilots a new weapon: the Light Discharge, an energetic projection of Getta Dragon developed to face the growing threat of the enemy. The Getta Robot heads to the city where it faces and eliminates the monster but the biggest obstacle is Hidler's mother ship but thanks to the new weapon designed by Saotomè, the enemy is soon defeated and the soldier must flee with his tail between his legs. .
