The Super Lady is the last survivor of Argonic Star, destroyed at the edge of the galaxy. To protect Earth's peace, she has continued fighting robots created by the evil Dr. Regzas. Regzas has always tasted defeat at the hands of Super Lady, harboring deep resentment. Then, Captain Joka of the National Defense Force appears before him, proposing a truce to reclaim public support stolen by Super Lady. As the price of negotiation, he offers Regzas Argonic Ore—the Super Lady's greatest weakness. At night, inside a factory, Regzas unleashes his rampaging robot, Argon Unit 1. This time, Super Lady is overwhelmed in an entirely different way. Argon Unit 1 runs on Argonic Ore, turning her greatest vulnerability into its power source. In this dire situation, can Super Lady achieve victory, or will she suffer a brutal defeat? The story concludes with a shocking outcome.
