January 2118. The chief inspector of the Criminal Investigation Department, Akane Tsunemori, receives a report about an incident on a foreign ship: the body of Professor Milicia Stronskaya has been found. Behind the incident is a group known as the Peacebreakers, a foreign paramilitary organization and a new outside threat targeting the professor’s research reports, known as the “Stronskaya Papers.” Meeting Shinya Kogami, a former fugitive from the Criminal Investigation Department, Akane is confronted with a case that soon exceeds her expectations. The Stronskaya Papers could reveal a truth that would shake the Japanese government, and even the Sibyl System, to its foundations. In this untold story, the missing link is revealed.
