This installment concludes the Police Academy flashback that began in File 1134.
After finally stepping inside the “Monster Mansion” in File 1135, our young Shinichi Kudo, Ran Mouri, and the five Police Academy cadets are about to uncover the truth behind the house’s shady occupants.
What motives are those mysterious men hiding, and how will the cadets dismantle their scheme?
Below you’ll find our spoiler-packed breakdown and early theories for Detective Conan File 1136, “A Once-in-a-Lifetime Encounter,” as published in Weekly Shōnen Sunday issue 1 (4 Dec 2024).
Detective Conan File 1136 “A Once-in-a-Lifetime Encounter” – Spoiler
The Police Academy flashback continues.
The cadets now realize the three shady residents are anything but day-traders, yet the men scramble to explain they merely “repair PCs.”
File 1136 Spoiler ① – Matsuda Uncovers a Hidden Room
Jinpei Matsuda spots a wall with a keyhole—but no doorknob.
After dismantling a double-layer drawer, he finds the key, unlocks the panel… and discovers a full indoor marijuana grow room.
Because cannabis requires strict temperature and lighting control, the electricity bill topped ¥30,000—exactly why the cadets flagged it.
File 1136 Spoiler ② – The Truth Behind “Yamamomo”
Rei Furuya explains the scrap of paper young Shinichi found.
“山モモ” mixes kanji and katakana to mimic the letters WEED.
The note’s “1 g ¥6,000” is the street price—proving the trio are drug dealers, not day-traders.
File 1136 Spoiler ③ – The Cadets Take Them Down
- Hiromitsu Morofushi quietly confiscates the gun the dealers brought.
- Furuya drops one man with a boxer’s left hook.
- Wataru Date tackles a second suspect who tries to flee by car.
- The third speeds off on a motorbike, but Kenji Hagiwara and Ran—riding the borrowed RX-7—corner him on a bike-only trail. Ran squeals, “That was fun!” even as the FD’s bodywork is left dented.
The commotion ends when Instructor Onizuka arrives and scolds the cadets—again.
File 1136 Spoiler ④ – A Pivotal Exchange Between Shinichi and Furuya
With the case wrapped, young Shinichi marvels, “So you really are police officers!” Furuya smiles:
Furuya「If you’re still a detective when you grow up, maybe we’ll meet on a case someday… Deal, Shinichi Kudo?」
Their connection is now firmly established.
File 1136 Spoiler ⑤ – In the Present, Amuro Puts It All Together
Back in the present, café waiter Toru Amuro (Furuya) fixes the Mouri apartment’s burst pipe.
When he greets “Conan-kun,” Conan suddenly recalls meeting this cadet seven years ago.
Conan also deciphers the café-master’s coffee label “te-ro-chi-chi-mo-mo” as a cipher for COFFEE.
But when Ran starts retelling the “Yamamomo 1 g ¥6,000” story, Conan panics—exposing the very tale Amuro needed to confirm his hunch:
Toru Amuro「I’d long suspected a resemblance… That boy is Conan Edogawa—which means he’s really Shinichi Kudo!」
File 1136 ends with Amuro’s discovery of Conan’s true identity now fully confirmed.
Detective Conan File 1136 “A Once-in-a-Lifetime Encounter” – Review & Theories
What first looked like a simple seven-year flashback turns out to be a major turning point for the entire series.
The reveal in this chapter comes from an angle no one saw coming, making File 1136 indispensable reading for Conan fans.
Below are the key talking points and why they matter going forward.
File 1136 Review & Theories ① – Toru Amuro Finally Deduces Conan’s True Identity
It’s official.
Hints sprinkled throughout the movie Black Iron Submarine suggested Amuro already suspected the truth, and File 1136 finally confirms it: Toru Amuro now knows that Conan Edogawa is actually Shinichi Kudo.
His line “I had my doubts, but now I’m certain…” seals the deal at 100 percent.
The big question is how Amuro—currently under orders from a mysterious elder to “investigate Conan”—will act on this knowledge.
File 1136 Review & Theories ② – Conan Realizes Rei Furuya’s Past Connection
The revelation cuts both ways.
Conan remembers that the Police Academy cadet he met seven years ago was Rei Furuya.
That means Shinichi once spoke to Amuro face-to-face in his own body, raising the stakes: Conan now knows Amuro could expose him at any moment.
How will Conan safeguard his secret—and what counter-measures will he take?
File 1136 Review & Theories ③ – Will Conan Recall His Encounters with Matsuda & Hagiwara?
The Police Academy team may disappear from the spotlight for a while, but Conan met Jinpei Matsuda and Kenji Hagiwara when they were still alive.
If future stories focus on Chisato Hagiwara, those memories could resurface and add emotional weight.
Fans should watch for any reference that triggers Conan’s recollection of his short-lived friendships with the late officers.
With Amuro’s discovery and Conan’s newfound awareness, File 1136 sets up a high-tension chess match that will shape the manga’s next phase.
