👀 SPOILER-FREE SUMMARY

The Detective Boys wrap up their Kurashiki adventure in this standalone filler conclusion that delivers exactly what long-time fans expect from a classic Conan puzzle episode. Conan, Ayumi, Mitsuhiko, Genta, and Professor Agasa work through the remaining riddles tied to the Peach Tree Club's time capsules, and the episode leans heavily into its intellectual challenge format. The pacing is methodical — each clue gets its moment before the next piece clicks into place. Tonally, it balances light suspense with the group's characteristic camaraderie, and the Okayama Prefecture setting gives the mystery a regional flavor that keeps things visually fresh. This is a deduction-forward episode rather than an action-heavy one, so expect satisfying logic chains over dramatic confrontations. Skippable for those tracking the main plot, but a solid self-contained mystery.

📍 ARC CONTEXT

This is Part 2 and the conclusion of the 'Momotaro Mystery Solving Tour' filler arc, resolving the time capsule riddles and murder case introduced in Episode 377. As a filler two-parter, it carries no implications for Conan's overarching Black Organization storyline. The next episode shifts to an entirely new setting and mystery with 'Case of the Long Sleeved Kimono at the Hidden Hot Spring on a Snowy Night.'
