I read the original novel after reading the first volume of the manga adaptation and have now continued on to the second volume of the manga. I can now see that it's a pretty faithful adaptation story-wise, but the fan-service art and the manga trope of self-censoring penises out of the art but showing everything else as if it were there really push this toward pure erotica, diluting and obscuring the dark undertones of the original book.

This volume gets us about halfway through novel. I'm going to stick around, because I'm very curious to see how the fourth volume handles the novel's conclusion. ( )
