It's the 2060's, and Japan has perfected "The MRI System," a piece of neurotechnology that, when given the brain of a person who died within the past 48 hours, can analyse the visual memories contained within; even being able to give scientists a look into what the deceased saw in their final moments. Needless to say, this is a highly regarded - and greatly feared - method that has been placed under stringent restrictions and is only authorised for use by a special police unit, Section Nine, for the investigation of baffling or high-profile crimes.

Aoki Ikkou is a talented newbie who has just been assigned to Section Nine. He initially has qualms about delving into people's most private moments and analysing their darkest fears and fantasies, but as he settles in with his teammates and warms up to his boss, the highly intelligent Maki Tsuyoshi, he becomes more and more competent at his job.

Though quick to develop pride in his career, Aoki still struggles to balance his family relationships and love life with his demanding workload, further complicated when he's drawn into the dark past and murky circumstances surrounding the outwardly cool and self-controlled but internally tormented Maki.

Note: The first chapter is a prologue that features the first case where the MRI method was used. Chapter 2 is where the main cast is introduced.

This is shoujo just like MPD Psycho is (was) shounen. As in, it's much more grisly and creepy than you might expect. But, as long as you can stomach that, it's a fascinating read, and definitely one of my favorites. Forensic sci-fi, drama, criminal drama, ethics, and romance, this has rich content from all over the board. Great for more mature readers who would like a dark and compelling story.

I love it. So expertly written. I've never been a big mystery buff but I get so addicted to reading these cases. And can I just say WHAT great character-development!!! i love Tsuyoshi so much haha. His and Aoki's relationship is def. interesting. Believe me the whole "plot" gets so much more interesting as you go on. It builds on in layers, subtly. I love that kind of stuff! And the art? Very beautiful. The mangaka is one of my top faves. biggrin

Oh, I forgot to add that one of the best things about this manga is how actually realistic it seems for a sci-fi themed story. There are so many bittersweet moments in here. The "evil" people like the murderers... u get to feeling so sorry for them and sympathizing them. It's great. I love how it makes everyone so human. I literally tear up sometimes. READ THIS!

I'm only on the 2nd chapter, but this is already more than I expected. It's dark, but good (plus, it helps that I like dark manga). The first chapter implies that
Spoiler (highlight to view)
the president was in love/infatuated with his daughter's lover
, but I found that to be a lovely component that made the first chapter great. It also has an incestuous flavor that I enjoyed (Yeah, I love the taboo). Worth the read -it's pretty different.

This really is a great series. It more of a dark manga; showing the a realistic portrayal of what it would be like if we could see into people's minds. The characters are deeper than they first seems to be and the plot always keeps you reading. I just wish someone would scanlate it again sad

Added this to my wish list because of the Zazen Boys song, "Himistu Girl's Top Secret". Who knows, there might be a connection, heh. I guess I'll have to wait until more chapters are scanlated. But, judging from the two previous comments, this series looks promising.

intriguing! Interesting! magnificent! (disturbing?) This is so awesome!
Besides deathnote, this one left me wanting for more stories!

My favorite genre shoujo have failed me numerous times (e.g.parfait tic)this one opens me to other excellent variety of manga!

Such a moving, thought-provoking story! Truly the best work by Shimizu Reiko I've yet read. Certainly among the best in the science fiction genre. The first chapter traces the events behind a future American president's death, and reveals the secrets he thought he'd carried with him to the grave. It's a truly beautiful chapter... Not disturbing in the least -- more poetic and romantic than anything!

The second chapter deals with a rash of teenage suicides in Japan. It's just as excellent as the first chapter, if more bloody and blatantly disturbing. Torsos are carved open and dissected in horrifying detail.

Parts of this manga waver between josei, seinen and shounen ai (yes, there is implied homosexual content, if no actual sex). But it doesn't matter that the manga is difficult to classify... Please don't miss it just because it doesn't fit into a genre that's easy to name!
