Cute girls, mecha armor and space invaders come together in this fast-paced anime tale about a mad scientist, Dr. Kishida, who assembles an enormous "female" megarobot, Ariel -- the supreme combat android -- to save the earth from extraterrestrial invaders. Maybe it's a good thing the suit is "piloted" by reluctant schoolgirls -- Kishida's granddaughters. The last thing they have on their minds is world domination!
