That being said, the plot can be boiled down to "MC gets sexually assaulted by the yokai of the week, but then his black winged protector shows up and rescues him" which is repeated for most of the book. This set up allows for the presentation of many different yokai and by extension a number of different erotic scenes. Those who like bondage/restraint/tentacle will most likely find it to be pleasing. I also enjoyed its horror elements as it nicely walks a fine line between scary and exciting.
The use of yokai in creating the erotic scenes were very creative and well drawn. The artist seems especially good a conveying textures; slime, goo, feathers, scales, etc.
The plot does eventually move beyond monster of the week and I liked the backstory and twists that came about (though they were a little rushed and could have used a bit more fleshing out). The ending feels rather final, but I would gladly read a second volume if it were to be made.
