Great manga to read if you are a man of culture. Although monster girls here are too human (author tries to give them plausibly realistic biology on the surface. Which will not survive in real world, but, well, this is just kind of "realistic" monster girls). They are in some weird spot between too human to be an actual monster girl and too monstrous to be considered human. Still, they are cute enough so whatever. A good mix of decent art, explicit illustrations, good story telling, walls of text about in-world "mumbo-jumbo" that easily can be skipped, and poor lame-ass cgi for scenes that was toocomplex for author to draw out.

Main positive point is that author adequately interweave scenes of violence and sex. Kill an enemy, then fuck an eternally grateful girl that you saved. Kinda like that, but with lots of flavor from different circumstances. It is more about gratification for actions of characters, than mindless sex for the sake of simple pron.
