A woman walks gracefully through the air, her cape fluttering behind her—her name is SUPER WOMAN. By day, she is Japan's rhythmic gymnastics representative at the Olympics; by night, she is a superheroine fighting against evil. Once again, she effortlessly defeats the monster sent by the alien Karahan Do Garufasu, who plots to conquer Earth. Suddenly, a man appears before her—Kuu Esmeralda, also known as SUPER GUY. He is a fellow Galactic Monster Control Officer and the beloved partner of SUPER WOMAN.
