I've been confused about the concept that I get when I hear about it, but not enough to catch my interest to actually watch.  It sounds like basically, it does to Shojo what One Punch Man did to Shonen, it deconstructs its main values and inverts them.  Instead of friendship, teamwork and innocence with magic girls, it's deception, betrayal and murder...with magic girls.  Likely also rape, given the genre.  Also the protagonist is really the villain and the sidekick is the victim or something, I dunno.

Unlike One Punch Man, which I can't stand, I'd imagine I might like this reworking of the Shojo tropes a little, at least enough to finish one of the chapters/seasons.  But then, I'm also presuming its all done to the extreme, so I'm imagining Battle Royale levels of disturbing imagery with cutesy pre-teens.  So...just Battle Royale, then.  And I barely made it through the first book before dropping that and leaving the rest of the collection to gather dust on the shelf.

This is probably going to be a horrible comparison, but think of the works of H.P. "Cthulhu Mythos" Lovecraft. The horror from Lovecraft's stories isn't from blood everywhere or edgy content (although sometimes it happens), but from the idea that the characters find themselves in something bigger that just can't be explained without losing their sanity, and shows just how futile their own existence is. In many ways, this feels like a Lovecraft story with magical girls in it.

a franchise similar to gundam

Context???

Yes because in the time I knew Seanaltly and Jesuszilla, neither really expressed any desire to rap.
