The heroine wears nothing but a floor-length hooded cape and a mask. Her private parts glow. Seeing them causes bad guys to collapse in anguish. She defeats evildoers with flying gymnastic moves that allow her superpower be used to maximum effect. The plot is inconsiderable -- it's there, but only to satisfy our superstitious belief that a movie has to have one. There are lots of cute Japanese girls in school uniforms. If you ever have an opportunity to see it, do so. You won't regret it.
