👀 SPOILER-FREE SUMMARY

A standout Detective Boys episode that raises the personal stakes by pulling Genta Kojima's family directly into the mystery. Expect the signature Conan formula — sharp deduction mixed with the lighter, comedic energy the Detective Boys always bring — but with an added layer of emotional weight as the case hits uncomfortably close to home for one of the group. The pacing leans into a slow-burn setup, characteristic of a two-part structure, spending time establishing clues and building tension rather than rushing toward answers. Conan remains the analytical anchor, but this is Genta's spotlight, giving his character more depth than the usual comic relief role. The tone balances suspense with genuine warmth, making it an engaging first half that earns its cliffhanger. A solid entry for fans who enjoy character-driven mysteries within the long-running series.

🔥 KEY MOMENTS

⚠️ Spoiler Alert!

The Haunted Armor Rumor

Conan, the Detective Boys, and their group arrive at the Beika Art Museum after hearing whispers about a suit of armor that allegedly moves on its own. The creepy legend sets the stage for everything that follows.

Casino Conversion Conflict

Curator Ochiai introduces the group to the museum's inner turmoil — new owner Manaka intends to gut the art museum and turn it into a casino. The staff's barely concealed hostility toward Manaka immediately establishes a room full of suspects.

A Gruesome Tableau

Inside the ominously named 'Hell Gallery,' the group discovers Manaka's corpse impaled against the wall by a sword, posed to mirror one of the gallery's own hellish paintings. It's one of the more theatrical crime scenes in the series, clearly staged with intent.

The Knight Attacks

Inspector Megure reviews the museum's surveillance footage, which appears to show a suit of knight's armor coming to life and attacking Manaka. The impossible footage turns the moving armor rumor into the case's central puzzle.

Conan Spots the Cracks

While the police take the footage at face value, Conan quietly picks apart inconsistencies in the physical evidence at the scene. His observations suggest the theatrical murder setup is concealing a very human — and very deliberate — killer.

📍 ARC CONTEXT

This episode follows the resolution of 'The Revolving Sushi Mystery' two-parter (episodes 549-550) and launches a fresh standalone case that spotlights Genta Kojima's personal life — a relatively rare focus for the character. As Part 1 of a two-episode arc, it handles all the groundwork and setup, leading directly into episode 552's conclusion where the full picture comes together.
