In the present, murders are solved not by investigations, but by memories. Using the removed brain of a victim, the members of Forensic Investigation Office Section Nine examine the person's last thoughts to determine a suspect and motive in the case. Many oppose the violation of their loved ones' private and personal memories; but what they don't understand is that behind the scenes, even the investigators themselves are often conflicted with their deeds. Aoki Ikko is one such man who struggles to overcome his own mental doubts about his profession, while trying his best to take down those responsible for the crimes.
Ryoko Yakushiji is the gifted and beautiful Superintendent of the Tokyo Metropolitan Police; no matter what the problem – science gone wrong or supernatural monsters – it seems there is nothing she cannot solve. With her new partner, the mild mannered Junichiro Izumida, she sets about tackling some of Tokyo's most terrible crimes. However, as Izumida quickly discovers, Ryoko's talent comes with a big ego and some strange personal baggage; cleaning up the streets of Tokyo becomes not just a matter of finding the bad guys, but trying to survive Ryoko's attitude problem as well!
The interaction of the office workers in the section, as well as the relationship between the protagonist and his boss really highlight the similarities between these two series. Add in a bit of supernatural or scifi element, and the two become a perfect complement to the other.
