One of the best horror and mystery manga I've read. The art is gorgeous. Definitely not for the faint of heart or those with weak stomachs. All the gory details of dead bodies are drawn without censors. It's a shame Dark Horse Comics stopped translating past Volume 14.
It's interesting, the plot of the manga has a good approach. Still, I see no special event that would really engage me in this manga. It is still ongoing so I accept this kind of incompetency. However, I would like to see in the future some changes that would actually make me say that it's good. I would not give any commentary about this, but I would see and give critics about this. :)
