I have never written a review before because I'm too lazy, but I can't believe this manga doesn't have one yet so here's my extremely short review:

Just as a warning, this manga is gory, it has uncomfortable moments involving minors, nudity and a bunch of other crazy stuff... If you still decide to read it then enjoy the story, it's diverse characters, and the AMAZING art!

As a horror manga lover I genuinely enjoyed this manga. I got hooked as soon as I started reading it, and since it's not long you can finish it in less than a day (at least I did)
Overall, if you're looking for a gory, ecchi, psychological manga with great art then this might be just what you're looking for! I personally recommend it ^.^
