This is by far one of the most original storyline which is lacking among today's mangas. Not many authors are willing to base characters on the obsessed or the morally lacking. But at the last verse at the end of the series, it shows that this series, is actually based on the same formula as most romance mangas. There are both the hero and heroine and how the hero saves the other but it honestly never really occurred to me. Maybe I'm rather slow. O_O but with such intent at the starting, the story really follows this motive but its interpreted in such a different way that I'm fairly impressed.
Art: 7
There isn't anything special. I'm not too keen about art but this manga lost its point in it because through out volume 5, I had mistaken a minor character as the main character. There wasn't much variation between the 2.
Character: 10
Superb. Simply original and superb. Though its a waste that there wasn't much background to the main character but its his lack of humanity that amuses me. The taboo word of inhumane gave me hope that there is still hope in modern literature, hope in authors to tackle the taboo themes.
Enjoyment: 9
The story despite its originality is more focused on its evolving of character. not so much on the mystery behind the crime and the genius of the main character, in fact its more on the psychological approach which also lacks. So don't expect some genius scheme of revealing the sick mind.
Overall: 8
This manga is woth the read if you want a change of the typical genres. If you want a change in main characters, try this manga. Though it may contain some gore which can be a tad too disturbing to some, its worth a read.
