👀 SPOILER-FREE SUMMARY

A standalone filler mystery that leans heavily into gothic atmosphere and supernatural tension. Conan, Kogoro, and Ran stumble upon a secluded mansion deep in the woods, where a fan club has gathered to conduct a séance for a vanished celebrity. The episode trades the usual urban crime-solving for something eerier — flickering candles, suspicious devotees, and a locked room setup that promises classic Conan deduction. The pacing is deliberate, prioritizing mood-building and character introduction over rapid-fire clues. Expect the first half of a multi-part mystery with strong horror-adjacent vibes, as Conan's rational mind clashes with the paranormal trappings surrounding him. Each fan club member carries their own suspicious energy, and the episode does solid work establishing the puzzle pieces before the real investigation kicks off. A strong setup episode for mystery purists.

🔥 KEY MOMENTS

⚠️ Spoiler Alert!

Lost in the Woods

Conan, Kogoro, and Ran stumble upon a secluded mansion deep in the forest, where they encounter a devoted fan club gathered to honor the missing idol Kira Miyahara.

The Séance Turns Sinister

During the ritual to contact Kira's spirit, supernatural phenomena erupt and a chilling voice resembling Kira's swears vengeance against those present. The atmosphere shifts from eerie curiosity to genuine fear.

Special Effects Exposed

Conan and Kogoro methodically debunk the ghostly occurrences, revealing them to be orchestrated special effects rigged throughout the room.

Hirasaka's Tampered Recording

Creator Reiki Hirasaka insists that his original recording was altered without his knowledge, pointing to an unknown manipulator pulling strings behind the séance.

Murder in the Locked Room

Shouko Utakura is found strangled inside the sealed séance room, transforming a debunked ghost story into a full-blown locked room murder case and setting the stage for the real mystery.

📍 ARC CONTEXT

This filler episode breaks from the prior standalone tennis court case and launches a new multi-part locked room mystery unconnected to the main Black Organization storyline. It serves as the first installment in a self-contained arc centered on the Miyahara mansion, with subsequent episodes expected to unravel the séance's secrets and the truth behind Kira's disappearance. No overarching plot progression here, but it's a quality entry point for fans who enjoy Conan's atmospheric, horror-tinged detective work.
