This is a satire of all the sexist nonsense from female-hero anime and carries over to a lot of female-hero films you see today.
Sexist camera angles are taken to extremes in this series, actually to the point of being funny rather than annoying like they are in so many productions. The transformation into a magical form that so often includes a hint that the person might be naked midway through now not only leaves no doubt but the machine causing the transformation actually grows hands and starts pulling clothes off her.
Not that women are the only objects of ridicule in this. The evil mastermind come creepy voyeur is so camp he should be teaching a masterclass in the subject.
