Itomura Satoshi (played by Kamikawa Takaya) is a part of the Metropolitan Police Department First Investigation Scientific Criminal Unit. He is in charge of personal effect of the murder victims, where his job is to identify the victims' items to help the investigation. He is not supposed to investigate the case or the murderer.
Itomura is a very curious person, even for the smallest thing, which always makes the detectives annoyed and angry. He believed that every single thing could deliver a message which the victims want to convey. His curiosity always led them to find out the truth, the real truth behind a murder case, and sometimes also led them to find out the murderer itself.
Oda Miyuki (played by Kanjiya Shihori), a rookie detective is also one of the detectives who gets annoyed with Itomura. Slowly, when Oda knows that Itomura is helping the victims who cannot speak anymore to convey their messages through the items, Oda started to feel moved and helped Itomura a little bit I guess. Muraki Shigeru (played by Komoto Masahiro), a scientist who always helped with the research of the items, is always forced by Itomura to help him in various way, which is sometimes quite funny.
Even though the story is nice and amusing, the character of Itomura which is very calm and slow became a minus point for me. A detective, mystery genre dorama usually has a very active and quite aggressive main character. Well, actually this makes the dorama unique, but just I prefer a mystery detective dorama with more action scene.
I gave this dorama 7.5 out of 10 points.
