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.
