Detective Tono Kazuyuki resigns from the Tokyo Metropolitan Police’s First Investigative Division but is unexpectedly appointed as an instructor at the police academy. Unprepared for the role, he is tasked with teaching theory about violent criminals—far from his hands-on investigative style. At the academy, he encounters naive young recruits, including the skilled and popular Miyata Eiji, whose life lacks the hardships and resilience required to become a true police officer.
