👀 SPOILER-FREE SUMMARY

The second half of this standalone filler mystery delivers on the tension established in Part 1, shifting into full deduction mode as Conan works to unmask a sniper terrorizing the city. Expect a tightly wound investigative atmosphere — Conan picks apart ballistic evidence and suspect alibis with the precision fans love, while Kogoro fumbles toward his own conclusions and Inspector Megure keeps the police procedural side grounded. The pacing ramps up from methodical clue-gathering to a more urgent climax as the pieces fall into place. This is classic Case Closed comfort food: a self-contained puzzle with genuine stakes, sharp reasoning, and just enough comedic relief from Kogoro's overconfidence to keep the mood balanced. If you enjoy the series' bread-and-butter murder mysteries, this conclusion satisfies without demanding any broader story investment.

🔥 KEY MOMENTS

⚠️ Spoiler Alert!

The Balloon Target Practice

Conan and the Detective Boys stumble upon a sniper zeroing his aim on a balloon tied to a remote-controlled boat — a chilling dry run that immediately signals something far more dangerous is in play.

The Calculator Code

The group discovers a calculator left behind by sniper Koichi Yamabe containing a coded message. It's a desperate breadcrumb from a man being forced into murder, and Conan's the only one sharp enough to recognize it.

Conan Cracks the Cipher

Conan deciphers Koichi's coded plea, revealing that criminals have kidnapped his girlfriend Eri and are coercing him into assassinating a district attorney aboard the Heisei Express train.

Race to the Heisei Express

With the assassination timeline closing fast, Conan relays his findings to the police and they scramble to intercept the train before Koichi is forced to pull the trigger.

Intervention and Rescue

Conan and the police manage to prevent the assassination on the Heisei Express and move to rescue Eri from her captors, dismantling the criminals' leverage over Koichi in one decisive stroke.

📍 ARC CONTEXT

This episode wraps up a two-part filler case that began in Episode 124, functioning entirely as a standalone mystery with no connection to the overarching Black Organization storyline. It serves as a breather between longer narrative threads, and the series transitions into the 'Traveling Drama Troupe Murder Case' arc immediately after. Viewers tracking only canon plot developments can skip this without missing continuity, but it's a solid detective outing for those who enjoy Conan's episodic cases.
