Synopsis by Mark Deming
This animated sci-fi adventure-comedy from Japan concerns A-ko, a schoolgirl with super-human powers whose friendship with the friendly but intellectually challenged C-ko is threatened when rich brat B-ko decides that she wants C-ko to be friends with her -- and no one else. A-ko finds herself attacked by giant robots, angry aliens, and female bodybuilders doing B-ko's bidding as the fight escalates to cosmic proportions. When not dealing with B-ko's lousy temper, A-ko also tries to help find an alien princess stranded on Earth.
