Looking for Sunday Conan chapter 1143 spoilers and in-depth analysis?
The mini-arc featuring Kogoro Mori and Eri Kisaki, which began in File 1141, now reaches its climax.
Last chapter was the investigation phase; this chapter delivers the solution!
Let’s dive into our spoiler-filled breakdown and fan theories for Detective Conan File 1143, “Like Smoke.”
Detective Conan File 1143 “Like Smoke” – Spoilers & Breakdown
At last, the mystery of the three identical paper bags reaches its climax.
As time ticks by, each suspect grows impatient and demands the return of “his” bag.
Private eye Kogoro Mori declares he has cracked every piece of the puzzle—and, together with attorney Eri Kisaki, begins to lay out the truth.
File 1143 Spoiler ① – Who Is “Assistant Director C” Really?
C previously claimed he needed to shower a film set with ¥10,000 notes for the movie’s finale.
Yet the callus on his right-hand middle finger is unmistakably a manga-artist’s pen bump.
Every model gun in his bag bears left-handed fingerprints and eraser shavings—exactly what you’d expect from an artist sketching reference poses with the barrel turned toward himself.
Worse, C shows zero familiarity with “bami tape,” the on-set marking tape any real assistant director uses.
His entire story is a lie.
File 1143 Spoiler ② – The True Identity of “Freeter B”
Cap-wearing B is next.
Eri presses him: isn’t he actually an A.D.?
Tape for floor marks clings to his pant leg, and he carries a jumbo marker for cue cards.
Conan pops open the milk carton from Bag #3—out gushes red liquid: a classic prank prop.
The sketchbook’s red construction paper turns blood-like when wet, confirming B works on a hidden-camera show.
His “big racetrack win” is also bogus. In horse-racing slang, “teppō” refers to a long-rested horse, not a handgun; any real bettor would know that. Chastened, B (and the exposed poser C) leave the restaurant.
That means the remaining “lawyer,” A, must own the cash-stuffed bag—and he promptly claims it.
File 1143 Spoiler ③ – A’s Next Move
After leaving the diner, A heads for Nishihaito Station and sits on a platform bench.
An ominous man appears behind him. A brags that he fooled “Sleeping Mori” with smooth talk, sneering:
A「He’s no ‘Sleeping Kogoro’—more like Smoky Little Kogoro!」
A then hands over the bag—about ¥100 million—to the stranger and exits for the street, hopping into the first taxi he sees.
File 1143 Spoiler ④ – Enter “Smoky Little Kogoro”
Surprise! Inside the taxi sit Kogoro, Eri, Conan, and Ran, surrounding A.
Kogoro had hidden his phone—still in call mode—inside the cash bag, recording both the insult and the hand-off.
The verdict: A is no attorney but an imposter.
Eri explains:
- A genuine Japanese bar badge is tie-tack style when first issued, not screw-back.
- The badge’s reverse lists the lawyer’s registration number—yet A “couldn’t remember” his own.
The moth-ball odor on the bills screams “mattress money,” suggesting an elderly victim’s savings. Conan deduces A stole it by posing as a lawyer.
A Was Part of a Bank-Transfer Scam Ring
Under questioning, A reveals everything.
Police rescue the elderly victim he tied up and tail the courier who received the cash.
A raid on the fraud ring’s hideout nets the entire syndicate, kingpin and all.
A, it turns out, was merely the “uke-ko,” the pickup man.
File 1143 Spoiler ⑤ – So Who Was Kogoro Meeting?
Earlier, Kogoro phoned a mysterious woman for advice on a present for his “high-school-aged daughter.”
Ran snatches his phone and spots a message from “Marron” arranging to meet at Café Callahan.
Everyone heads over—only to find Midori Kuriyama, the paralegal from Eri’s office, who allegedly called in sick today.
It turns out Kogoro wasn’t just asking about Ran’s gift; he’d also been quizzing Midori about the best Christmas and White Day presents for Eri and how she reacted when she received them. Eri blushes but starts to say:
Eri「Idiot… If you want to see my reaction, why don’t you just—」
Before she can finish, a flustered Kogoro lives up to the nickname “Smoky Little Kogoro,” vanishing like a puff of smoke!
Detective Conan File 1143 “Like Smoke” – Review & Impressions
The mini-arc that spotlights Kogoro Mouri and Eri Kisaki wraps up here, setting the stage for the upcoming movie “One-Eyed Afterimage”.
The closing pages even tease a rare, tender side of Kogoro—always a treat. Below are a few quick thoughts and theories!
File 1143 Review & Theory ① – An Easy Chapter for Identifying the Bag’s True Owner
This mystery proved fairly straightforward—almost every prediction landed.
The clues were laid out so clearly that even a fully awake Kogoro could solve them (which means most readers could, too!).
“Sleeping Kogoro” never makes an appearance, neatly linking this chapter to the film’s timeline.
Let’s hope Kogoro shines just as brightly on the big screen.
File 1143 Review & Theory ② – The Unresolved Clue About Itakura Taku and the Black Organization
Despite an entire page of setup back in File 1141, the lingering thread about Taku Itakura and the Black Organization isn’t addressed here.
It feels like we’re only seeing the spark that will ignite a future storyline.
Still, one takeaway emerges: the way a cat’s cry can be mistaken for a baby’s suggests the “infant Rum” theory around Renya Karasuma is looking stronger than ever.
File 1143 Review & Theory ③ – A Wholesome Kogoro Moment
Kogoro’s suspicious phone call turned out to be nothing shady at all—he’d been asking paralegal Midori Kuriyama for gift advice for both Ran and Eri.
The alias “Marron” (“Chestnut”) was a clever nod to Kuriyama’s family name.
In the end, we’re reminded that Kogoro’s feelings for Eri run deep, right down to his trademark smoke-bomb exit.
Can we expect some on-screen couple moments in “One-Eyed Afterimage”?
We’ll be watching closely!
