During a career counseling meeting, Yukina Shirahane learns that she is currently failing at Tateyama International High School, although determined to visit Mars someday. After school, Yukina and Mika Ogino go to the United Nations Kurobe Laboratory, a research facility where their parents work. Meanwhile, the Ministry of Defense detects a meteorite heading for Japan that divides between Toyama and Nagano as it enters the atmosphere. Minoru Aramata shows Yukina a large black cube and a gigantic geoframe found while excavating for the Kurobe Dam sixty years ago. Suddenly, one of the meteorite fragments crashes near the United Nations Kurobe Laboratory. A huge rose-colored geoframe called the Headless and small geoframes called Cactuses appear. The research facility dispatches shield-like geoframes called Dwarves to battle the Cactuses, while director Hiromi Shirahane authorizes pilot Tom Borden and navigator Liu Shenmei in the GAUS 1 to fight the Headless. Yukina opens the Cube after touching a glowing red panel, revealing Kennosuke Tokisada Ouma, a naked man who kneels and calls her princess. He relentlessly defeats one of the Cactuses that enters the building, while Tom and Shenmei manage to defeat the Headless outside. Kennosuke is then subdued by six security guards.
