There was once a high-tech robot which saved the earth from aliens. People have long forgotten how to operate this humongous machine and it has been placed to an isolated place. The Doctor believed the mobility of this machine and never gave up in finding a suitable pilot for the robot. However one day, he found that the robot had became a gathering space for 8 middle school girls. The girls kept on calling the robot like a friend “Robot san” “ROBOSAN” without listening to the Doctor’s warnings.
