Another manga that I follow, Bloody Monday.
Summary from One Manga:
A virus deal clinched in Russia on the Christmas eve. Purpose: unknown. Two clues: a mysterious lady “Maya”, one of the gangsters, and “Bloody Monday”, the keyword for the project.
Then an incident happened in far-distant city of Tokyo. Fujimaru Takagi, a second grade student at Mishiro Gakuin high school, is commissioned to find out the truth by Public Security Investigation Bureau for his great ability as a super hacker. Now, Maya, approaching to Fujimaru, as his high school teacher…
The story is about as believable as Live Free or Die Hard (a “super hacker” can hack into anything with his laptop in mere seconds). I find it highly amusing, taking into account my relation to computer science, since it follows the mainstream perception of “hacking.”
Nevertheless, it’s entertaining enough to merit reading though I believe it is tagged mature due to some scenes of violence (blood and gore).
