A Russian spy is found murdered in Japan, with the only clue to the reasons for his death being a memory chip he managed to hide from his murderer. The Third-I branch of the Public Security Intelligence Agency recruit Fujimaru Takagi, a brilliant hacker known as “Falcon”, to decode the chip, which contains a video file documenting a viral outbreak in Russia where thousands are killed, known as the Christmas Massacre.

Things become further complicated when Fujimura’s father, a high ranking official within Third-I, is falsely accused of murdering his superior when he receives further information related to the Christmas Massacre, and the code name “Bloody Monday”.

The terrorist Maya Orihara, who was responsible for the incident in Russia, is now in Tokyo in order to recover the memory stick to stop Third-I from knowing the truth of a terrorist plot in Japan. She goes under cover as a teacher at Fujimaru Takagi’s High School. From there it becomes difficult for Fujimaru to determine who he can trust as he uses his high-level hacking skills to try and save the country and unravel the mystery of Bloody Monday and the cult behind it.

This manga is as good as Until Death Do Us Part. Only this time, you got a middle-school kid who is a superb hacker. Of course, he got a group of friends who can help him and also with him is the agency where his dad is working for.

There’s no anime version of it (I’m pretty sure there will be one). But there’s also a live-action version too except that the main characters aren’t like middle-school kids.

Anyway, onto the series, there’s a lot of conspiracy, betrayal and gore (yes, there’s a lot of gore but not Tarantino gore). In fact, there’s this quote in TV tropes that says, “24 in Japan”. So, it’s really like 24 except the main character is no Jack Bauer.

The manga ended last year and it has a sequel which is currently ongoing.
