👀 SPOILER-FREE SUMMARY

A standalone filler episode that wraps up the two-part Detective Boys adventure centered on a treasure map and a clever canine companion. Expect a lighthearted mystery driven by teamwork rather than high-stakes danger — Conan and the Detective Boys follow a series of cryptic 'X' markings across multiple locations, piecing together clues with their usual blend of enthusiasm and deductive reasoning. The pacing is steady and approachable, leaning more into the adventure and comedy side of the show than its darker thriller elements. This is classic Detective Boys fare: group camaraderie, playful banter, and a satisfying puzzle that doesn't require any knowledge of the show's overarching plotlines. If you enjoy the kid-detective dynamic and lighter Conan outings, this delivers exactly that energy without pretending to be something bigger.

🔥 KEY MOMENTS

⚠️ Spoiler Alert!

The Mysterious Map

The Detective Boys discover a series of 'X' marks on the back of a seemingly ordinary piece of paper, sparking a full-blown investigation across multiple locations.

Following the Trail

Conan, Ayumi, Mitsuhiko, and Genta visit each marked site one by one, gathering scattered clues that slowly form a coherent picture tied to a murder case.

Coeur Sniffs Out Evidence

The great dog Coeur proves indispensable by leading the team to hidden evidence at one of the locations that the kids would have otherwise overlooked entirely.

Connecting the X Marks

Conan pieces together the relationship between the marked locations and specific events surrounding the crime, revealing that the map is essentially a confession trail left behind by the perpetrator.

Confronting the Killer

Armed with the evidence gathered from every 'X' location and Coeur's discovery, the group identifies and confronts the suspect, closing the case in classic Detective Boys fashion.

📍 ARC CONTEXT

This is the second half of the two-part 'Great Dog Coeur's Triumph' filler storyline, directly concluding the events set up in Episode 663, 'The Mountain Beetle Chase.' It has no bearing on the show's main narrative threads involving the Black Organization or recurring plot arcs. The season moves into Episode 665, 'Suspicion of Initial K,' which shifts back toward standalone mystery territory.
