👀 SPOILER-FREE SUMMARY

A filler two-parter kicks off as Conan, Ran, Kogoro, Haibara, and the Detective Boys trade their usual urban stomping grounds for the volcanic landscapes of Mt. Aso in Kumamoto. This is a scenic, slower-paced opener that prioritizes atmosphere and setup over rapid deductions. Expect gorgeous location work highlighting fire and water — volcanic terrain and natural springs — while the group settles into vacation mode before the inevitable mystery surfaces. A new character, a young boy named Justin, enters the picture and adds a fresh dynamic to the group. The tone leans into the adventure side of Conan's DNA, with lighthearted interactions and sightseeing carrying most of the runtime. This is foundation-laying through and through: clues are scattered, suspects are introduced, and the real case is still taking shape.

🔥 KEY MOMENTS

⚠️ Spoiler Alert!

Justin's Stamp Collection

At Mt. Aso, the group meets a boy named Justin who proudly shows off his tourist stamp collection from around the mountain, establishing his connection to the area's landmarks.

The Bench Drop

During a rest stop, Conan and the others witness a classic dead drop — one man leaves a bag on a bench, another retrieves it and leaves behind a stuffed toy. The exchange immediately raises red flags.

Ayumi's Dangerous Good Deed

Ayumi tries to return the abandoned stuffed toy to the man, but he aggressively rebuffs her. His panicked reaction draws police attention and triggers a chase with Conan in pursuit.

The Stuffed Toy Swap

During the collision between the fleeing suspect and Justin, their identical stuffed toys are accidentally switched — meaning Justin unknowingly walks away with the one containing stolen recipes.

Conan Cracks the Swap

Conan pieces together that the toys were swapped in the chaos and realizes the stolen recipes are now in Justin's possession. He sets out to track down the boy before anyone else does.

📍 ARC CONTEXT

This standalone filler episode follows 'A Dispute Over a Platinum Ticket' and launches a two-part mystery tour arc set in Kumamoto. It functions entirely as setup, introducing the location, new characters, and early threads of the case. The conclusion arrives immediately after in episode 721, 'The Mystery Tour of Fire and Water (Kumamoto Part),' where the investigation ramps up in earnest.
