There is only one word that describes this manga - tension. If you liked "Death Note" and "Spiral", you will love "Bloody Monday", it exudes the same feeling of mental chess, intrigue, and continuous feeling of tension. Death lurks in every corner, there is no feeling of assurance that we get from other mangas where you are confident that the main characters typically do not die - not an assumption you can make with this one. The story twists, turns, thrills, and surprises.

The art work is very good too, the character expressions are well drawn, but I didn't pay a lot of attention to the art since I was so caught up in the story. The characters are a little cliche, a high school student with genius hacking skills, and his comrades comprising a high school karate champion and an archery champion seems rather convenient, yet they are extremely vulnerable, and even arrogant of their own skills... little do they know what they're dealing with.

The series is ongoing, so perhaps all this praise is a little premature, but from the 13 chapters that have been released, this is shaping up to be quite interesting. I might change my opinion as the series progresses, but for now I recommend this to anyone who enjoys a good old fashioned thriller. You will not be disappointed.
