I'm honestly surprised this manga is being published at all. It started crazy, then one-ups itself with each new arc and nothing is off the table as far as taboos go.
And yes I enjoy it a lot, I rate it as my main guilty pleasure along with Satanophany.
Think the weakest part of this manga is how predictable it can be. Every character is deliciously evil and any character that is not is murder fodder so it gets kind of boring.
