Season overview

The second season of Seven Detectives depicts a period of significant transition for the Twelfth Section of the Tokyo Metropolitan Police Department. Long characterized as the graveyard of detectives and a banishment room for personnel who cannot be fired, the unit undergoes substantial structural and personnel changes. Amagi Yu, an eccentric detective previously assigned to the section from the Lost and Found Centre, transfers to the mobile investigation unit. Meanwhile, Katagiri Masatoshi transitions from his role as the section chief to lead the Criminal Affairs Division. The unit also experiences the departure of Yamashita Takumi, who moves to the Future Crime Prediction Centre. Amidst these shifts in the organizational environment, the arrival of forensic science professor Domoto Juntaro introduces new dynamics to the team. These developments fundamentally alter the composition of the Twelfth Section, forcing the remaining members to adapt to a new professional landscape while continuing their investigative duties within the Tokyo Metropolitan Police Department. The season focuses on how these individual career trajectories and the introduction of new expertise impact the overall functionality and reputation of the unit once known primarily for harboring hardened detectives.
