Unfair

Yukihira Natsumi is a no-nonsense, intelligent Tokyo homicide cop known as the department’s “number one” case closer, who nevertheless also has a bad reputation for not working well with others and pushing the limits of the law. As she sees it, her only job is bringing in the bad guys, and the results are all that counts. However, she is haunted by a hostage case five years prior in which she had to pull her weapon and kill a man, which earned the ire and distrust of some of her coworkers and members of the community. To bring balance to her life, Natsumi must find a way to deal with her demanding work, the aftermath of a divorce, and caring for her young daughter—all while chasing down a serial killer who’s taunting the police with serialized short stories that foretell the next murder with no time to spare.

Nine months after the death of Yukihira’s partner by suicide, the case of his death is closed due to insufficient evident. But Yukihira, suspicious of a string of police officer suicides, begins to suspect there is more to this…

Mochizuki Akira, who replaced Yukihira Natsumi, begins her job at the Tokyo Metropolitan Police Department. A female high school students asks her to find her missing father. Shortly afterwards, the phone at the police department rings. A man on the other end of the call states that he kidnapped 4 men. The female high school student’s father is among the 4 men kidnapped.

The special team of the #1 investigation unit at the Tokyo Metropolitan Police Department learns of a horrifying video transmitted via the Internet. Viewers who watch the video are asked to answer a series of “yes or no” questions. If the answer is wrong, a man wearing a mask shoots a hostage. As the yes or no answers become more heated, the video is broadcast on live TV.

Detective Mochizuki, who was kidnapped as a child, continues to receive regular psychiatric treatment from Dr. Tachibana on her recommendation. One day, a disturbing doll arrives at the Metropolitan Police Department. The doll’s arm bears the same burn mark that was inflicted on Mochizuki by her kidnapper 20 years ago, accompanied by a message reading “Saikai wo Nozomu” (Wishing for Reunion).

Is this a sign that her kidnapper from two decades ago wants to meet her, or is it a declaration of resumed kidnapping activities?
