I know this is a fetish manga, but it honestly reads more like a bizarre horror, sometimes dipping into very black comedy. The stuff about body modification and turning the "yapoos" into completely dehumanized creatures, on top of them seeing humans (or at least humans of the dominating race) as gods reminded me of Shinsekai Yori, though SSY doesn't have the weird racial stuff, or the bodily fluid obsession. God, I hope this shit wasn't an inspiration. That was a very good anime.
Even more than the racism (which is off-putting in itself), it's insane to me how much thought was put into even the most putrid and/or minute details. There are multiple walls of text dedicated to how this twisted society handles offal alone, for fuck's sake. So much scat and urophilia. The living furniture made of rearranged flesh from multiple bodies is pretty horrifying, too. Reading this makes me want to turn vegan, not own any pets, and fully subscribe to atheism.
I kind of hope the author of this died alone and never bred. Whatever mistake happens in your brain to make you imagine the content of this story shouldn't risk being spread.
