Major spoilers: Bourbon’s true allegiance, the Scarlet storyline, Scotch’s death, and Conan’s identity through manga File 1167. Movie examples are identified separately.
Bourbon is Rei Furuya, a Japanese public-security officer infiltrating the Black Organization. Tooru Amuro is his everyday cover identity, not his real name. He shares Conan’s goal of defeating the Organization, but maintaining his cover and carrying out police work mean that he is not an ally who reveals everything.
There is another important answer: in Volume 107, File 1136, Amuro concludes that Conan Edogawa is Shinichi Kudo. Knowing that they are the same person does not establish that he knows the drug mechanism, Haibara’s identity, or every other secret around them.
One person, three names
Rei Furuya is his real name and police identity. Tooru Amuro is the name he uses as a private detective, Kogoro Mouri’s apprentice, and an employee of Café Poirot beneath the Mouri Detective Agency. Bourbon is the codename he uses inside the Black Organization.
He is 29 and combines deduction with physical skill, driving, cooking, information gathering, and infiltration involving disguise. Those abilities let him appear at home in very different settings.
The friendly Poirot employee, the demanding investigator protecting Japan, and the intelligence specialist sounding out a target are not three separate people. They are roles with different obligations. The same smile can feel reassuring in one conversation and unsettling in another, depending on what he is trying to learn.
An undercover investigator, not a loyal Organization member
Bourbon is a NOC: an investigator who conceals his true identity while operating inside a hostile organization. He has earned sufficient trust to receive a codename and sensitive assignments, while his underlying mission is to work against the Organization.
That places him on Conan’s side in the larger conflict, but it does not make every immediate interest identical. He can withhold information, prioritize public-security work, and investigate Conan himself. Understanding that distinction is more useful than assigning him a simple friend-or-enemy label.
In the movie-only example Black Iron Submarine, Bourbon passes Organization information to Conan. The scene illustrates cooperation within that film; it does not remove the limits surrounding what he knows or shares in the manga.
His specialty is getting close enough to learn secrets
Bourbon uses conversation, observation, and deduction to uncover identities, weaknesses, and concealed information. This differs from Gin’s more direct emphasis on lethal operations. Amuro’s place beside Kogoro and at Poirot shows how naturally he can enter a target’s daily life.
He investigates Shuichi Akai’s survival and later receives a direct assignment from Rum concerning Shinichi. Such work demonstrates practical importance, but a formal rank equal to Gin or Vermouth is not established. Responsibility for a major investigation is not a published organizational chart.
When are Amuro, Bourbon, and Rei revealed?
Volume 75: the detective called Tooru Amuro
Amuro debuts in Wedding Eve (Part 1) and Wedding Eve (Part 2), Episodes 719-720 (Japanese episodes 667-668), adapted from Volume 75. He appears as a private detective, becomes Kogoro’s apprentice after the case, and begins working at Poirot.
His friendly manner makes him fit easily into the familiar setting. Rewatching after the later revelations changes the meaning of that easy access: getting close to Kogoro also lets him observe the people and mysteries around the agency.
Volume 78: the Bourbon identity
The train story runs from The Jet-Black Mystery Train (Departure) to The Jet-Black Mystery Train (Destination), Episodes 753-756 (Japanese episodes 701-704), in Volume 78. Amuro participates with Vermouth in the operation targeting Sherry and identifies himself as Bourbon.
This reveal places the approachable detective inside the Black Organization, but it does not yet reveal his true police allegiance. The threat is real from Conan’s perspective at this stage. The sudden weight of an alcohol codename makes the earlier smile look very different.
Volumes 84-85: the public-security officer behind Bourbon
The Scarlet storyline spans Episodes 832-836 (Japanese episodes 779-783): The Scarlet Prologue, The Scarlet Pursuit, The Scarlet Intersection, The Scarlet Return, and The Scarlet Truth. Across Volumes 84-85, Bourbon’s true position as Rei Furuya, also called Zero, becomes clear.
Amuro suspects that the supposedly dead Shuichi is alive and tries to expose Subaru Okiya. Conan, Shuichi, Yusaku Kudo, and Yukiko Kudo prepare a response. Their contest over the staged death and disguise leads to the second reversal: the apparent Organization enemy is himself an infiltrating investigator.
The police revelation does not make his hostility toward Akai disappear. Undercover obligations, official work, and grief over Scotch remain entangled. He is more understandable after the reveal without becoming a straightforward partner.
What do Conan and Bourbon know about each other?
Conan understands the three identities
Conan knows that Amuro is Bourbon and that Bourbon’s real identity is Rei Furuya, a public-security officer. The Mystery Train and Scarlet stories disclose different layers rather than one simultaneous revelation.
He deals with Amuro with that undercover position in mind. Their interaction also involves the secrets around Akai’s staged death and Subaru’s identity. Outwardly they can remain a schoolchild and a café employee while both understand that a much larger investigation is operating underneath.
File 1136 connects Conan to Shinichi
The decisive manga point is Volume 107, local File 3, or global File 1136, A Once-in-a-Lifetime Encounter. This English chapter title follows established secondary usage. Amuro’s accumulated doubts about Conan converge on a contradiction involving memories from seven years earlier.
He had already recognized that Conan was no ordinary first-grader: the child’s deduction, activity behind Sleeping Kogoro, and involvement in Akai’s staged death were all reasons for scrutiny. The later memory supplies a different kind of evidence, connecting ability to identity.
Seven years earlier, elementary-school children Shinichi and Ran Mouri met Rei and his police-academy friends. The boy now presenting himself as seven-year-old Conan knows that encounter as his own memory. Amuro connects him to the Shinichi who was already a schoolchild at the time and concludes that they are the same person.
A memory that initially seems warm and incidental becomes evidence against the present cover identity. That is the pleasure of the reveal: the story does not merely give Amuro another display of Conan’s intelligence; it gives him something Conan’s apparent age cannot explain.
The Bride of Halloween is a separate movie precursor
In the movie-only example The Bride of Halloween, Conan speaks about events involving the police-academy group seven years earlier as though he had been there. Amuro reacts to the oddness but does not pursue it in that moment.
That movie-only reaction does not establish that he has already identified Conan as Shinichi or worked out the physical transformation. A suggestive reaction and a completed deduction are different evidence levels. The manga conclusion discussed here belongs to File 1136.
Identity is not the whole APTX 4869 secret
Amuro identifying Conan as Shinichi does not confirm that he knows how the transformation happened. The material discussed here does not establish that he knows Gin forced Shinichi to take APTX 4869 or that de-aging was an unintended effect.
Nor is it established that he knows the drug’s detailed effects, the temporary antidote, Ai Haibara’s identity as Shiho Miyano, her inheritance of the drug research, or the existence of other de-aged people. Those are separate pieces of information, not automatic consequences of recognizing one person.
His past connection to Elena Miyano and the Miyano family does not fill in those gaps. It may provide a reason for interest, but it is not proof that he has identified the present Haibara. Even after Conan’s identity has been recognized, a substantial boundary of unshared information remains.
Has he reported Conan’s identity to anyone?
Through the File 1167 scope discussed here, no scene shows Amuro reporting his Conan-Shinichi conclusion to Rum, Hyoue Kuroda, or the mysterious elderly man with a cane. He has not openly told Conan that he has reached that conclusion either. An absence of a shown report is not proof of every offscreen conversation.
Rum and the elderly man gave him different targets
Rum orders Bourbon to investigate Shinichi, a man thought to have died. Separately, in Volume 105, an unidentified elderly man directs Amuro to investigate Conan himself. The elderly man’s identity, affiliation, and purpose remain unclear; he should not be classified as Rum’s ally or definitively unconnected to the Organization on this evidence.
By File 1136, the two targets meet in Amuro’s deduction: Shinichi and Conan are the same person. That creates a conflict between what Bourbon may be expected to report and what Rei may have reasons to protect.
Protecting Conan could explain withholding the discovery, but the motive is not established. He may still be investigating, or there may be other considerations. The story has not yet supplied a complete explanation for the silence within this scope.
The tea meeting does not settle when he learned the answer
Amuro investigates the Kudo Residence and the secrets around Subaru and Akai. A later tea meeting brings him together with Yusaku, Yukiko, and Akai, but there is no established disclosure of Conan’s identity at that meeting. It should not replace File 1136 as the demonstrated point of Amuro’s own conclusion.
Everyday politeness therefore conceals a dangerous question: who will receive his answer, and in what form? The possibility is more unsettling than a simple declaration that one side now knows all of the other’s secrets.
Who knows which part of Bourbon’s identity?
Knowing Amuro is Bourbon
Conan, Shuichi Akai, James Black, Jodie Starling, Andre Camel, Yusaku and Yukiko Kudo, and Hyoue Kuroda are identified with knowledge of Amuro’s Bourbon identity in the events discussed here. On the Organization’s side, Gin, Vermouth, and Rum recognize the operative using the Amuro cover.
The content and timing of that knowledge matter. Knowing that the Poirot employee is Bourbon does not automatically mean knowing his real name, exact police role, or all the circumstances of his infiltration.
Knowing the real police allegiance
Conan and Akai know that Bourbon is an undercover public-security officer. Kuroda gives Rei instructions within public security, while Yuya Kazami treats him as his superior. Hiromitsu Morofushi, Rei’s childhood friend and fellow infiltrator, knew his true position while operating as Scotch.
The wider FBI circle includes James, Jodie, and Camel, but the precise extent and timing of each person’s knowledge of the real name Rei Furuya and his police role remain unclear here. They should not all be treated as having learned every layer at the same moment.
Yusaku and Yukiko appear to understand that Amuro is more than a loyal Organization operative and belongs on the police side. The exact point at which his real name was shared with them is not established here.
The Organization knows the cover, not a proven exposed NOC
The Organization recognizes Amuro and Bourbon, but his true allegiance remains concealed in the material discussed here. Rum assigning him a sensitive investigation demonstrates operational trust, not a discovery that Rei is a police officer.
It is not confirmed that Rum has identified or specifically suspects his public-security affiliation. Rum’s proximity as Kanenori Wakita makes the situation tense, but proximity alone does not establish the content of his suspicion.
The movie-only The Darkest Nightmare provides a separate example of the consequences of exposing undercover agents: once their covers fail, the Organization moves to eliminate them. That film illustrates the stakes without proving that Rum has reached the same conclusion about Bourbon in the manga.
Bourbon’s most important relationships
Rum: a superior demanding an answer
During the Kyoto school trip, Shinichi temporarily regained his original body and appeared in front of many people. News of that appearance spread online, alerting the Organization to the possibility that he was still alive. Rum responded by ordering Bourbon to investigate, using his information-gathering skills to pursue the anomaly.
Bourbon receives work that matters to the Organization while Rei has a different underlying mission. His Public Security Bureau connections and his Organization responsibilities cannot simply be treated as one chain of command. Finding an answer can be as dangerous as failing to find one when different parties want it.
Vermouth: cooperation supported by secrets and leverage
Bourbon and Vermouth cooperate in intelligence and disguise-based operations, including the attempt to secure Sherry on the Mystery Train. He also uses her impersonation abilities while testing the people around Akai for information about his survival.
Bourbon holds a secret concerning Vermouth that gives him leverage, and she sometimes complies reluctantly. Their cooperation rests on abilities and pressure as much as trust. No marriage, parent-child relationship, or romance between them is established here.
Their light exchanges can therefore carry a cold undertone. An easy manner does not mean that either has stopped calculating what the other knows or can be made to do.
Rye and Scotch: the death behind the hostility
Scotch was Hiromitsu Morofushi; Hiro is Rei’s nickname for him, not his full name. The two had known each other since childhood and both entered public security before infiltrating the Organization.
When Scotch’s cover was exposed, Akai confronted him on a rooftop, revealed that he was an FBI infiltrator, and tried to stop him from taking his own life. Approaching footsteps were actually Rei’s, but Scotch believed pursuers from the Organization were arriving.
Scotch died by suicide while destroying the phone holding information about colleagues and family. Akai did not kill him; he had tried to save him. Rei arrived and understood the scene as Akai having let his friend die, creating the resentment behind their later encounters.
The devastating irony is that Rei was hurrying to help, while the sound of his arrival contributed to Scotch’s final decision. The tragedy is not only a misunderstanding between two surviving men; it lies in the help that never reached their friend in time.
Rye, Bourbon, and Scotch form the whisky trio: one FBI operative and two public-security infiltrators beneath alcohol codenames. But Rei’s full acceptance of the circumstances and complete reconciliation with Akai are not established. A common enemy does not erase what he carries from that night.
An ally whose knowledge and obligations have limits
Bourbon is Rei Furuya beneath the Amuro cover. Conan knows those three identities, and File 1136 gives Amuro a firm conclusion that Conan is Shinichi. Neither fact makes all the surrounding secrets common knowledge.
The drug, Haibara, possible antidotes, undisclosed reports, and conflicting duties leave room for caution. What makes Bourbon compelling is that protecting someone and investigating them can be part of the same life, while the familiar routine at Poirot continues over both.
