On December 30, 2015, the captain of the space exploration ship Luxion, Noriko Takaya's father, passed away in space. The girl Noriko Takaya was determined to become a space pilot like her father and worked hard for it. Six years later, Noriko Takaya became a junior high school student. The school opened a course for robot driving. Third-year senior sister Kazumi Amano has superb driving skills and is loved by everyone. She is called "sister" by the younger students. The new coach Mr. Ota came to the school to select two students to become space pilots. "Sister" was selected without any suspense, but Noriko Takaya, who lacked robot driving experience, was also selected as a space pilot! With excitement and doubts, Noriko Takaya began her life as a space pilot, but what she did not expect was that her mission was to drive a robot to fight the alien creatures that killed her father. The responsibility of fighting for the survival of mankind suddenly fell on the girl Noriko Takaya. How will her future be written?
