Plot

A Russian spy is discovered dead in Japan, with the only evidence to his death being a memory chip he managed to conceal from his killer. The Public Security Intelligence Agency's Third-I section hires Fujimaru Takagi, a skilled hacker known as "Falcon," to decipher the chip, which includes a video file depicting a viral epidemic in Russia that kills thousands, known as the Christmas Massacre. Things become even more complicated when Fujimaru's father, a high-ranking officer inside Third-I, is wrongfully suspected of murdering his supervisor after learning more about the Christmas Massacre, later receiving the code name "Bloody Monday." Maya Orihara, the terrorist responsible for the incident in Russia, is currently in Tokyo in order to recover the memory stick and prevent Third-I from learning the truth about the terrorist plan in Japan. She disguises herself as a teacher at Fujimaru Takagi's High School. From there, Fujimaru struggles to know who he can trust as he utilises his high-level hacking abilities to try to save the country and solve the mystery of Bloody Monday and the cult behind it.
