Case Closed Episode 681

👀 SPOILER-FREE SUMMARY

Conan's long-running series shifts into high-stakes thriller mode with this gripping opener to a multi-part arc. The usual detective procedural gives way to genuine tension as Detective Takagi vanishes without explanation, and his colleagues—especially the fiercely devoted Detective Sato—scramble to understand why. The episode escalates sharply when the Detective Boys receive a mysterious package revealing a live feed of Takagi bound and unconscious, transforming this into a desperate race against time. The pacing is tight and urgent, stripping away the show's lighter comedic elements in favor of raw suspense. Expect mounting dread, strong character dynamics within the police force, and the kind of personal-stakes mystery that hits harder than a standard case-of-the-week. This is Conan at its most intense, leveraging beloved recurring characters to raise the emotional investment considerably.
