I heard about this monger through the anime man and once I heard him compared it to the likes of Saw and Battle Royale I knew I immediately had to check it out I'm a huge horror junkie so I wanted to see what all the fuss was about and I was disappointed. I don't get very much horror vibe from this there's no good atmosphere the seven main characters range from despicable and unlikable especially in regards to the lesbian character who I couldn't wait to watch die I to just bland or okay, the art style is just very serviceable and nothing really all that special there are times where the arch really shines especially during the sex scenes conveniently enough are actually times where the art can look pretty good but due to a lack of proper horror atmosphere it's almost pointless. There are some scenes that put a smile on my face such as some of the actions of the hostess character and the guy who is a cultist is the closest thing to an interesting character, and the death of the lesbian character was extremely satisfying alongside the death of the unlikable lesbian character in her flashback was equally as gratifying, however the final nail in the coffin for me and what really kills this manga for me is only two out of the six volumes are translated so I actually can't read the other for so I can't continue the story I don't understand how this manga has been around for almost 2 years now and it hasn't been fully translated BULLSHIT.
my personal recommendation skip this at least until it gets fully translated and check out Elfen lied and Another they are much better or experiences and are worth your time.
