👀 SPOILER-FREE SUMMARY

A standalone filler two-parter kicks off as Kogoro, Ran, and Conan trade the courtroom for the scenic Kanmon Strait on vacation. The change of scenery brings a slower, more atmospheric opening — expect nostalgia-heavy character introductions as a group of old friends reunites after twelve years under bittersweet circumstances: honoring a deceased friend and celebrating an engagement. The episode leans into the emotional weight of unresolved histories and fractured bonds before the mystery elements begin surfacing. Pacing is deliberate, prioritizing setup and interpersonal tension over action. If you enjoy Conan's travel-episode formula — new location, new suspects, simmering grudges masked by pleasantries — this delivers exactly that foundation. The tonal blend of warm reunion and creeping unease signals that something darker lurks beneath the nostalgia, setting the table for Part 2's payoff.

🔥 KEY MOMENTS

⚠️ Spoiler Alert!

Kogoro's Lucky Vacation

Kogoro wins a contest and drags Conan and Ran to the scenic Kanmon Strait, where his celebrity as the 'Sleeping Kogoro' immediately draws attention from a group of four old friends.

The Businessman's Hostile Offer

A brash businessman crashes the group's dinner and pressures one of the friends to sell their business. The confrontation turns ugly, with the friend firmly refusing and the rest of the group closing ranks against the outsider.

A Body by the Strait

The aggressive businessman turns up dead, instantly transforming the vacation into a crime scene. Conan's instincts kick in as the circumstances point squarely at someone within the group of friends.

Cracks in Old Friendships

Conan and Kogoro dig into the four friends' shared history and begin uncovering long-buried grudges, hidden debts, and personal secrets that reframe the dinner confrontation in a far more sinister light.

Threads to the Past

Early clues start linking the murder not to the business deal itself, but to unresolved events from the group's past — setting up a tangled web of motive that carries directly into Part 2.

📍 ARC CONTEXT

Coming off the courtroom-focused Episode 298, this episode pivots entirely to a fresh setting and a new cast of suspects, marking the start of a self-contained two-part filler mystery. It has no direct bearing on the overarching Black Organization storyline or ongoing character arcs. Part 2 follows immediately, so this functions purely as the buildup half — establishing the victim pool, motives, and emotional stakes before the inevitable crime drops.
