👀 SPOILER-FREE SUMMARY

A standalone filler episode that leans into Conan's lighter comedic side while still delivering a mystery worth chewing on. Conan, Kogoro, and Ran cross paths with two sports reporters who look eerily alike but can't stand each other, setting up a case built around rivalry, mistaken identity, and the murky space between appearances and truth. The tone balances humor with suspense — expect the usual sharp deductions from Conan but wrapped in a more playful package than the heavier canon arcs. The pacing is self-contained, making this an easy watch without prior episode commitments. If you enjoy the one-off detective puzzles that explore quirky human dynamics rather than advancing the overarching Black Organization storyline, this episode delivers exactly that kind of satisfying, low-stakes intrigue.

🔥 KEY MOMENTS

⚠️ Spoiler Alert!

The Restaurant Showdown

Conan, Kogoro, and Ran witness Hashizume and Kagazume — two eerily similar Nichiuri Sports reporters — locked in a vicious public argument over a stolen will that once led to an attempted murder. The tension between the doppelgängers makes it clear this grudge runs deep.

The Swapped Travel Mug

Hashizume accidentally grabs Kagazume's travel mug on his way out of the restaurant. What seems like a trivial mix-up between two men with matching taste becomes the linchpin of the entire case.

Death on the Riverbank

Kagazume is found dead by the river, poisoned by cyanide laced into his coffee. Hashizume's fingerprints on the mug immediately cast suspicion his way, but Conan senses the setup is too clean.

The Stolen Will Connection

Conan digs into the stolen will incident that fueled the feud between the two reporters. The old attempted murder case reveals layered motives that transform the poisoning from a simple revenge killing into something far more calculated.

Conan Unravels the Truth

Conan reconstructs the killer's precise sequence of actions, connecting the mug swap, the cyanide delivery method, and the buried history between the two men. The deduction exposes how bitterness over the past was weaponized into a meticulously staged murder.

📍 ARC CONTEXT

This episode follows the two-part 'Counselor Kisaki's SOS' arc, which centered on a tense kidnapping case involving Eri Kisaki, making this standalone outing a tonal cooldown before the series moves on. As a confirmed filler episode, it has no bearing on the main narrative threads but serves as a breather between serialized storylines. It leads directly into 'Result of the Draw,' another episodic case.
