So the idea of "body horror" as a genre or generic marker is that you are being transformed into something intrinsically and personally monstrous and everything is terrible. Right? So I figure the reverse of body horror is when you are transforming yourself into something (conventionally) monstrous because it's awesome and beautiful.

And the core idea of the magical girl genre is about undergoing a transformation into a prettier and more perfect version of yourself -- becoming more capable and self-actualized, then performing that capability aesthetically (prettier) and through ritual combat against physical embodiments of negative and destructive psychic forces (more perfect).
I figure? After the first time you have to defend your friends' lives by going toe-to-toe against a monster-of-the-week, your idea of "pretty" is going to change pretty damn quick. Fast and strong and efficient and shiny and bulletproof, and taking down a demon before it even gets a WHIFF of your designated love interest; THAT's pretty. And thus, our heroine's mystic-gem-fueled magical girl transformation gradually becomes more and more inhuman, but, and here's the thing, she is totally cool with this, because she A: has a job to do, and B: is in the process of adopting an aesthetic of function. And the monsters of the week are stuck dealing with eight feet of shiny glittering motion-blurred blade-fingered lantern-eyed (ribbon-bedecked, glass-armored, short-skirted, and let's be clear here, you get a super-legit sparkly transformation sequence before each battle) insectile terror.
