Season 1

A sadistic criminal is turning his victims into human flower pots. Detective Amamiya Kazuhiko is called out of early retirement to investigate the case, which is tied to horrific events in his past. His new wife goes missing and a mysterious cult with barcodes tattooed on their eyeballs surfaces to wreak havoc on the city.

A brutal serial killer cuts babies from their mothers' womb in what appears to be a copycat crime from five years earlier. All of the women have barcodes tattooed on their eyeballs. The victims, under some sort of hypnosis, purchase the surgical quality knives used to kill them the day before their murders. As Detective Amamiya's wife wanders the city in a trance, he discovers someone from his past is involved in the crime wave.

Detective Amamiya and the police team are investigating the mass suicide of forty girls from a posh high school. Amamiya goes undercover as a high school teacher to find out why and learn more about a new generation of barcoders, many of whom are students at this militaristic high school. Chiaki Kuriyama guest stars.

Perfectly severed body parts with numbers cut into them are discovered in a field. In a nearby arcade, two rival youth gangs battle each other and Amamiya's wife is taken prisoner by a gang leader. The Police Chief tries to put together more of Amamiya's hidden past with the assistance of a one-eyed snuff filmmaker.

Cult members spontaneously combust when the barcoder network is infected. The burn victims are taken to the local hospital where a lonely employee's cyber girlfriend tells him to kill people. Detective Amamiya and his team lock down the hospital, while strange things happen on the secret 13th floor.

The Police Department denies that the barcode case ever existed in a massive cover-up attempt. Three remaining members of the investigation team decide to continue working on the case on their own. The Police Chief's entire family dies under mysterious circumstances. Amamiya tracks down the baby stealer to a remote cabin in a snowstorm for a final showdown to recover his own missing child.
