Honestly, I love horror manga, but this one was disgusting—and unlike others, i didn't think that it held any profound meaning. (Yes, I did notice the biblical allusions and I still think that)
The art style was cool, but the story follows a sociopath with a god complex who's obsessed with pedophilia, violence, rape, and scat. I don't know why everyone in the comments thinks that it's well written—It's meaningless shock horror. The main character isn't particularly well developed—and all the other characters are completely 2-dimensional. Not only does the story have no meaning, it has no structure: it doesn't really build to a climax, it just ends.
Honestly, I wouldn't subject yourself to reading this—go read some Junji Ito or Frankenfran or Shintaro Kago or Chi No Wadachi.
