I'm dropping this manga at chapter 9 primarily because the manga wasn't what I expected. I was under the impression it was about Bloody Monday, and not a group of teens trying to prevent Bloody Monday. It reads like a Hollywood action film as opposed to an apocalyptic disease story. It has a poor perception of how hacking works; but if you enjoy Hollywood style spy stories you'd probably enjoy this manga.

I found that it feels like the story is being made up as it goes with things not making coherent sense, for instance an antagonist says something like 'I hope he doesn't investigate my alibi or else I might be in trouble (or have to do something about him)', but when he does investigate it the alibi checks out. While there's probably an explanation latter on it doesn't make sense that the person would be worried about it if its so easy rectified. So you could say that, like Hollywood it tries to build suspense in the now and not in the story as a whole over time. So again, if you enjoy campy action spy 'thrillers' you'd probably enjoy this manga.
