👀 SPOILER-FREE SUMMARY

A filler conclusion that wraps up the two-part 'Most Useful School in the World' case with the cerebral energy Conan fans expect. The episode leans heavily into deduction sequences as Conan and Kogoro work through the final layers of a missing artifact mystery, with supporting characters Yoko Okino and Mikihiko Kamisuwa adding texture to the investigation. Pacing is brisk and reward-oriented — this is a resolution episode, so expect the satisfaction of watching puzzle pieces click into place rather than slow-burn tension. The tone balances the series' signature lighthearted comedy beats with genuine suspense during the reveal. As a standalone filler case, it demands no knowledge of the overarching Detective Conan mythology, making it accessible but also skippable if you're tracking only canon developments. Solid comfort-food detective fare.

🔥 KEY MOMENTS

⚠️ Spoiler Alert!

Elimination of Hiding Spots

Conan systematically searches the studio, ruling out every possible location where the priceless vase could have been stashed during the rehearsal. Each dead end sharpens his focus toward a more unsettling conclusion.

Oki's Tell

Conan picks up on subtle behavioral cues from Shinobu Oki — Kimijima's own disciple — that betray her connection to the vase's disappearance. Her nervousness around her fanny pack becomes the critical thread Conan pulls.

The Vase Was Destroyed

In a sharp deductive leap, Conan concludes the vase wasn't hidden intact — it was shattered and its fragments concealed inside Oki's fanny pack. The realization reframes the entire case from theft to deliberate destruction.

Conan Confronts Oki

Conan directly confronts Shinobu Oki in front of the group, laying out the full chain of evidence from the missing vase to the crushed remnants she's been carrying. The tension in the studio peaks as Oki's composure finally cracks.

The Motive Unveiled

Conan begins to reveal the deeper motive behind Oki's act and hints at a hidden truth about the vase itself — suggesting the priceless artifact may not have been what everyone believed, setting up a dramatic resolution.

📍 ARC CONTEXT

This is Part 2 of a self-contained filler two-parter, resolving the mystery set up in Episode 636. It carries no weight for the series' long-running canon plotlines, so viewers focused on the Black Organization or Conan's identity arcs can skip without consequence. The next storyline, 'Solving Mysteries at the Red Leaf Palace,' follows immediately, continuing the season's episodic rotation of standalone cases.
