Hunting for Sunday Conan chapter 1137 spoilers and deep-dive theories?
File 1137 kicks off a brand-new arc right after File 1136 wrapped up the seven-year flashback linking Shinichi Kudo to the Police Academy trio.
This new story—set in Nagano and positioned as a prelude to the upcoming movie “One-Eyed Afterimage”—reunites us with the Nagano Prefectural Police and lays crucial groundwork for what’s to come.
The chapter’s official title is “The Sacred Light of the Dead” marking File 1137 as the first installment of the Nagano mini-case.
Below you’ll find our spoiler-filled summary, early theories, and quick reactions to Detective Conan File 1137.
Detective Conan File 1137 “The Corpse-Lighter” – Spoiler Breakdown
The chapter opens with Conan Edogawa, Ai Haibara, and the Detective Boys—Genta Kojima, Mitsuhiko Tsuburaya, and Ayumi Yoshida—riding in Professor Hiroshi Agasa’s Beetle en route to Nagano Prefectural Police HQ.
The kids were supposed to spend a ski week with Kogoro Mouri and Ran, but Kogoro caught a cold, so the duo stayed home.
Before they left, Kogoro asked Conan to drop by Nagano HQ on his behalf.
Haibara still remembers detectives Yui Uehara and Kansuke Yamato by their unforgettable nicknames, “Half-Kill” and “Almost-Kill.”
File 1137 Spoiler ① – Arrival at Nagano Prefectural Police
Waiting at the entrance is Inspector Uei, who hands the kids a specialty souvenir: Shinshu soba Katsuchiyo—the exact brand Kogoro asked them to pick up.
With time to spare, the Detective Boys accept a guided tour of the station.
Seeing the children, Inspectors Kansuke Yamato, Takaaki Morofushi, and Uei reminisce about their own childhood adventures.
File 1137 Spoiler ② – A Chance Encounter in the Station Cafeteria
Over lunch the Detective Boys are approached by a four-member content crew:
- Kaori Nanjō (video editor)
- Shichisuke Kasai (manager)
- Yūta Kitakura (cameraman)
- Tamaki Itō (on-camera host, famous as a horror influencer)
The group, called the Compass Detective Club, films “haunted spots” for their channel.
They reveal they were once five: three months ago their lodge burned down, killing Kaori’s older brother Takehiko Nanjō.
A recently restored, charred smartphone from the fire shows childhood photos of the team wearing matching detective badges—echoing the Detective Boys’ own start.
File 1137 Spoiler ③ – The Compass Crew’s Next Destination
The crew traveled to Nagano to investigate an old border legend straddling Nagano and Shizuoka: the apparition known as “The Corpse-Lighter” (Shibito no Mitō).
They also hope to contact Takehiko’s spirit. Their shoot is set for Hakuryū Ski Resort—which, by coincidence, is where the Detective Boys are headed.
File 1137 Spoiler ④ – Night Filming at Hakuryū Ski Resort
Both groups reach the charred lodge near the slopes, then hike to a secluded corner of the resort for the séance.
Host Tamaki plants a candle, caps it, and chants “Takehiko… Takehiko…” hoping to summon the Corpse-Lighter.
Nothing happens—until Tamaki turns to leave.
Suddenly her left arm bursts into flames out of thin air. The chapter ends on that chilling cliff-hanger.
File 1138 continues the mystery… stay tuned for more Nagano arc revelations!
Detective Conan File 1137 “The Corpse-Lighter” – Review & Theories
The new Nagano arc is finally underway!
Below are quick impressions and the potential clues we spotted—perfect background reading before the next chapter drops.
File 1137 Review & Theories ① – A Smartphone That May Link Back to Hiromitsu Morofushi
The charred phone recovered from the late Takehiko Nanjō feels like more than a throwaway detail.
Recall that Hiromitsu “Hiro” Morofushi (a.k.a. Bourbon’s late Public Security comrade) blew out the data-loaded handset in his final moments, later entrusted to his brother Takaaki.
This new “lost phone” could trigger flashbacks—or even parallel Hiro’s tragedy.
File 1137 Review & Theories ② – Another “Border Case” Déjà Vu?
A mystery at the Nagano–Shizuoka border instantly calls to mind the earlier Gunma–Nagano rivalry that featured Inspector Kansuke Yamato and Gunma’s Inspector Yamamura.
That case blended local folklore with childhood ties between the detectives—exactly what we see here with the Compass Detective Club.
Though this time the action stays inside Nagano, don’t rule out more back-story about Hiromitsu or the Shizuoka force.
File 1137 Review & Theories ③ – Likely a Four-to-Five-Chapter Mini-Arc
Weekly Sunday cases often wrap in three chapters, yet nobody has died and the Nagano duo (Yamato & Morofushi) barely featured in part one.
Add the film tie-in to “One-Eyed Afterimage” and this feels more like a four- or five-part storyline.
Expect flashbacks, folklore deep dives, and a bigger payoff before the movie hits theaters.
File 1137 Review & Theories ④ – Was the Spontaneous Fire Caused by Alcohol Vapors?
We still lack hard data on why host Tamaki Itō’s sleeve ignited.
One realistic culprit is a highly volatile alcohol. Ordinary ethanol won’t self-ignite, but a higher-grade solvent—or clothing pre-treated with flammable sanitizer—could ignite under the right temperature and oxygen mix.
Keep an eye on fabric type, wind direction, and any hints of spilled liquids in File 1138.
