SYNOPSIS: PART I - In the final week of the Showa Era Year 64 (1989), a girl goes missing in Gunma Prefecture. A hefty ransom was demanded for her safe return—and paid—but her body was found two days later in a car boot. The investigation was deemed a failure and Mikami is demoted to the police force’s public relations department.
Fourteen years later, with a year left before the case officially closes, ex-detective Mikami discovers anomalies in the original investigation. However, his current position as Press Director is to uphold the public image of the police department. Lacking the authority to launch further investigation on the case, he must find other ways to pry out answers amidst the politicking within the police force.
