This anthology-style mystery series is part of the D‑5 PROJECT, centered around Detective Office 5 - a long-running private detective agency in Kawasaki. Each detective is known only by a number rather than a name (e.g., Detective 596, 532), with standalone stories featuring different characters and surreal, quirky cases.
