👀 SPOILER-FREE SUMMARY

A standalone filler episode that leans into the Detective Boys' adventurous side, trading urban settings for the winding mountain roads of Mt. Ryushin. Expect a lighter, excursion-driven first half as Conan, Ayumi, Mitsuhiko, Genta, and Professor Agasa enjoy the scenery and each other's company before the tone shifts into suspense territory. A roadside incident triggers Conan's investigative instincts, and the episode pivots into a compact mystery that rewards attentive viewers without demanding any prior plot knowledge. The pacing balances breezy outdoor exploration with genuine tension once the case emerges. If you enjoy the Detective Boys dynamic—their bickering, teamwork, and wide-eyed curiosity—this episode delivers that energy in a self-contained package. No overarching plot progression here, but solid comfort-food mystery for series regulars.

🔥 KEY MOMENTS

⚠️ Spoiler Alert!

Crash on Mt. Ryushin

A car suddenly veers off the mountain road and crashes near the Detective Boys' campsite, turning a peaceful outing with Dr. Agasa into a potential crime scene. Conan spots a suspicious man wearing sunglasses watching the wreck from above.

The Dark Blue Paint Chip

Investigating the crash site, Conan discovers a chip of dark blue paint on the wrecked vehicle — evidence that this wasn't a simple accident but a deliberate hit-and-run.

Mitsuhiko Cracks the Code

Mitsuhiko stumbles upon a coded message that leads to a secluded hideout in the mountains. Unable to resist the mystery, he convinces Genta and Ayumi to follow the trail without waiting for Conan.

Stolen Cars and an Armed Man

The three young detectives uncover a hidden cache of stolen luxury cars, but their investigation goes sideways fast when the sunglasses-wearing man confronts them armed and dangerous.

Conan and Agasa to the Rescue

Conan pieces together the kids' trail and arrives with Dr. Agasa just in time to intervene, preventing the armed criminal from harming Mitsuhiko, Genta, and Ayumi and bringing the stolen car ring to light.

📍 ARC CONTEXT

Sandwiched between two other standalone outings, this filler episode follows the self-contained 'The Entrance to the Maze: The Anger of Colossus' (Episode 208) and precedes 'The Water Palace of Five Colors Legend Part 1' (Episode 210), which kicks off a more ambitious two-part mystery. It sits in a stretch of episodic cases with no bearing on the series' main narrative threads, making it entirely skippable for viewers focused on overarching plot but a pleasant detour for fans of the Detective Boys' group adventures.
