I get its a bloody and violent manga, but the lack of logic its such in the violence it ends up making you laugh (like breaking someone's nose so badly it looks like its just a hole, but the person still being able to breath even with their mouth covered, the psycho chick of a mc being so strong she can easily stab through solid bone like It's butter, but not a door, etc). The fetishistic aspects of it don't help (I mean to each their own but...), let alone the apparent reason all of this started...
Idk, I like revenge stories but this is kinda tacky, I guess. It's by all means not a series that is inviting it's readers to think, that's for sure.
