A whimsical story of the yaoi genre but with the appeal of a detective novel. Although the Incubus character is quite interesting and I guess the author wants the viewer to understand how savage this character is and actually he is a good person and protects Manuel because he wants him to "go to heaven". However, this transformation is not convincing especially when in Manuel's hospital flashback, where we see an Incubus named Naruko, who is very good with children, the complete opposite of this character in the first chapters. Not to mention the character Osmond thought was very important, but ended up being lackluster.The fact that Manuel could magically speak naturally didn't convince me either. This story is quite difficult to read so the relationship of Incubus and Manuel did not give me much emotion. I'm not a fan of the yaoi genre so if this was Succubus it would be easier for me to read. Sensitive scenes are really hard to watch for me. But anyway the plot of this story is quite attractive and can be made into a movie. Actually that is the talent of Nishin Masumi when he knows how to create dramatic and sensational situations in the twists at the end of the chapter or the end of the story, the way the characters clash and the conflicts happen right away instantly and what follows are both engaging and entertaining, if you don't believe me you can watch "Feeding Lamb", of course if you're into yaoi and guro genres it's perfect.
