I really liked this manga because of how, although it was rather strange, alot of it was possible and I could really see it happening. To be honest, the art wasn't all that great, but the story and the characters were really awesome. If gore offends you at all, this really isn't for you. It was really hard to find. Something about this story just entranced me, which is really the only reason I read it to the end, because it started off kinda boring and slow. Really I have found all of the Hino Hideshi manga I've read to be entrancing to some point,
and most of them have very...strange? art, not really typical manga style at all. Anyway, if you like gore, I would say you should give this manga a chance, although it's definitely not for everyone.
