Disclaimer: I received an e-ARC from netgalley in exchange for a review.

I was super excited to check this manga out when I saw it (magical girls fighting a war? That's always an interesting genre embracing cuteness and really, truly messy storylines of child soldiers), but after having read this first volume I now wish I had read the reviews first. This manga includes (as is unfortunately much too common, but I've managed to avoid it through reading reviews in most cases so far) depictions of nude ten year old girls, heavily sexualised content surrounding the magic system (where magic can be shared through kisses to heal people) and worst of all, the fact that the school nurse (who maybe is trans and misgendered a lot, or a crossdresser, either way a "pervert teacher") also kisses her students to heal them. I don't think I have to explain why such a depiction, especially in manga, which is already so often bad in its sexualisation of underage character and negative stereoptical portrayals of trans characters, is bad and harmful. Not only does it sexualise children, it also portrays a gendernonconforming, possibly transgender, adult as a perpetrator of said child abuse. Besides that there are quite a lot of nonconsensual kisses between the children themselves, which are never examined and instead portrayed as normal.
While I do think an exploration of institutionalized child abuse as would probably be much too common in a school set in such a militaristic war-like setting could be interesting, this is not what seems to be happening in this manga at all and I will not be reading other Volumes.
The art style is nice, but not enough to save any of the bad magic system, that's dependent on the massive sexualisation and exploitation of children.
