Set in a futuristic Japan, in an era when brain scanners have been perfected to a point where governments are able to retrieve information, memories and data 5 years in the past. They are even able to recheck a dead person’s memories back in the 5-year time period. In the present time, murders are no longer solved through severe scrutiny under investigations but using the memories of the long lost dead. The Forensic Investigation Office of Section Nine specializes in these types of research. They remove the brains of the dead victims in order to examine the dead person’s last moments of his life in order to determine a suspect and motive for the murder. Even though the relatives of the dead victim opposes to this kind of investigation, they can hardly do anything as it must be done to bring the criminals to justice. Despite their good intentions, even the investigators themselves feel it is something unethical and immoral in doing so, making internal conflicts within themselves harder to deal with rather than the actual deed itself. The story revolves around the story’s protagonist, Aoki Ikko as he goes through his life dealing with crime and injustice and going through a dead man’s memories to find clues about his murder. As he tries to take down the bastards responsible for the crimes, he is left doubting himself whether he is doing the right thing or bad despite the means. As the crimes escalate, the investigators of the National Research Institute of the Police Forensics Laboratory must now weigh the ethical choices provided to them in the ultimate invasion of privacy as they delve into the minds of the dead victims to solve crimes.
