Miru mo Muzan is a horror/hentai so it's a little hard to get it up while reading. A few of the stories were about ghosts and the others were just about raping.
The stories were a little twisted for me but I will say for the ones not about cumdumpster/slavery the were original but I can't say i cared for them.
The artwork I would have to say was very good.......... gory but good.
The characters weren't totally dumb and got tricked or blackmailed into being a slave. The male characters were just a little to evil and everyone of them had a foot long and as
big as my forearm penis which also made the artwork a little more gory.
Overall besides the artwork and the one story not about rape (still had slavery in it) can't really say i liked anything from this book.
