I'd like to start by saying this series messed me up in a serious way. It's totally inappropriate for pretty much any sane person and is not recommended to anyone under any circumstances. The themes are really, really dark and sickening. It's pretty much madness and insanity in manga form. That being said, the art was good enough and the moral argument was pretty damn profound. So, it was philosophically deep, but the author could've gotten the point across without mentally scaring the reader. If anyone else has read this I'd like to hear your thoughts. If no one else has, I'd like to leave it at this.
