Answer ~ Keishichô Kenshô Sôsakan(2012)

Answer is a Japanese crime drama following Deputy Inspector Shinkai Akira, a sharp-minded career officer reassigned to lead the Tokyo Metropolitan Police's Evidence Verification Section. Tasked with reviewing closed cases, the unit is meant to be little more than a rubber-stamp bureaucracy. But Akira takes the work seriously, uncovering overlooked evidence and procedural errors that point to wrongful convictions. As forensic science advances and DNA testing exonerates innocent prisoners, her determination to validate cases properly—and find the true perpetrators—clashes with her cynical, unmotivated team and the police establishment's preference for swift closure over accuracy. Arisa Mizuki stars as the determined investigator who uses her sharp instincts and sense of justice to overturn settled cases and expose systemic failures in criminal investigation.
