“Who are you?I will definitely let you go home.

"The job of the Unidentified Persons Consultation Room of the Metropolitan Police Department is to identify the unknown remains and return them to their families.Investigator Sakura Mita (Koshiba Fuka) is a weirdo who was voluntarily assigned to this remote department.She has a friend, Tsukimoto Makoto (Oshima Yuko), who is ten years older than her, and their personalities and interests are completely opposite.Although they quarreled with each other as soon as they met, everyone wanted more unidentified people to return to their families.

Contrary to these two newcomers, their bosses Tonegawa (Kotaro Yoshida), Horiguchi (Shigeyuki Totsugi), and Muto (Ikki Hankai) are all working professionals who are dawdling around in the workplace. The office is always lifeless and has no sense of tension...

Teshima (Abe Ryohei) and Nazu (Yagi Miki), the young aces of the Investigation Section 1 and Kesouken, came to ask for assistance in the investigation.The human skeleton model in a middle school in Tokyo turns out to be real human bones.The identification results showed that the white bones were the body of a person who died a year ago, and it might be a homicide.”The age of the victim was estimated to be between 25 and 30“——Nazu's report made Tsukimoto hold his breath.

Mita Sakura said enthusiastically:”We must find out the identity of the white-bone remains!%.

Then, things took a turn for the worse.Nishikawa (Makoto Sakamoto), a middle school science teacher, admitted that in order to prepare corpses as specimens, he used drugs to turn them into bones.Nishikawa is a taxidermy fan who entered the Tama Mountains in search of animal carcasses, where he saw a man he had never met jumping off a cliff.He thought this was a perfect opportunity to make a human specimen, so he took the body back, but said "I didn't kill anyone"...

With the assistance of Director Hayase (Takashima Reiko) of the Science Research Institute, the identity of the corpse was successfully discovered based on the relics held by Nishikawa.

but…...

The man's wife said "No, not my husband" and refused to claim the body for some reason... Did the man really commit suicide?Why did the family refuse to claim it?Sakura & Makoto, a pair who are ten years apart, run to find out the truth...!!
