I read this a few months ago, looking for a more dark or graphic manga to read. The story is very original, and the manga did a great job at exploring themes like the value of a human life, when is it okay to kill someone, etc. I also feel like the manga does a good job at portraying the main character’s apathy and his twisted view of originality, and how he views people who he thinks aren’t unique. The mangaka also does a good job at drawing the gorey scenes and the illness and nightmares the main character has that can only be comparedto a drug trip. I recommend giving this one a read
