# Seven Detectives (2015) — Television & Cinema Intelligence Dossier

> **Archytele Living Vault Canonical Record**: https://www.archytele.com/show/seven-detectives-2015

## Executive Summary & Cultural Positioning

Seven Detectives is a television series that premiered in 2015. The show revolves around Yū Amagi, a slightly eccentric detective who has been assigned to the Twelfth Section of the Tokyo Metropolitan Police Department's First Investigative Division from the Lost and Found Centre. This division is commonly referred to as the "graveyard of detectives" and is ridiculed as the "banishment room where hardened detectives who cannot be fired are sent." The Twelfth Section is comprised of elite and somewhat eccentric detectives, including Kōsuke Samura, Takumi Yamashita, Keita Nagasawa, Tamaki Mizuta, and Masatoshi Katagiri. Amagi appears to be fixated with time, which seems to have no direct relation to the cases being investigated.
