What kind of relationship do Vermouth and Bourbon really have?
Are the rumors that they are married, related, or romantically involved true?
Vermouth and Bourbon often work together on Black Organization operations. Vermouth excels at disguise and infiltration, while Bourbon is skilled at gathering information and reasoning through a target’s secrets. Their abilities make them an effective pair whenever a mission requires them to blend into ordinary society.
What keeps them from being ordinary coworkers is the secret between them. Bourbon knows something important that Vermouth is hiding, and his unfinished reference to “the boss’s…” suggests that it concerns the boss of the Black Organization. The exact answer has not been revealed.
Bourbon is also hiding a decisive truth of his own: behind his public identity as Tooru Amuro, he is Rei Furuya, an officer of the Public Security Bureau who has infiltrated the organization.
They stand beside each other without revealing what they truly want. They cooperate, yet either one’s hidden agenda could turn the partnership against the other. This cold distance is what makes their dynamic so compelling.
This article examines their working relationship, the marriage and family theories, Vermouth’s unresolved secret, and the major stories in which the two appear together.
Vermouth and Bourbon’s Relationship at a Glance
Vermouth and Bourbon are collaborators who carry out Black Organization missions together.
That does not make them partners who trust each other wholeheartedly.
Vermouth is a high-ranking woman in the Black Organization who specializes in infiltration through elaborate disguises and altered voices. Bourbon is an Organization codename. The man using it also operates publicly as Tooru Amuro, while his real role is Rei Furuya of the Public Security Bureau.
Furuya infiltrated the Black Organization as Bourbon in opposition to it. Although he and Vermouth appear to belong to the same side, their underlying objectives are not identical.
The simplest description is a dangerous mission partnership: each uses the other’s abilities while secrets give them leverage over one another.
They Are Not Confirmed as Spouses, Relatives, or Lovers
Vermouth and Bourbon are not confirmed as spouses, parent and child, or romantic partners in the provided story material.
They often act alone together, and Vermouth sometimes addresses Bourbon with easy familiarity, so certain scenes can make them seem unusually close. What the story actually depicts, however, is contact created by Black Organization assignments.
There is no available conversation, shared past, or family information that establishes romance or a blood relationship. Bourbon is a twenty-nine-year-old Public Security Bureau officer working undercover. Vermouth has played both actress Sharon Vineyard and Sharon’s supposed daughter, Chris Vineyard, while her appearance has remained unchanged for decades.
Their apparent closeness is better explained by a shared life of concealed identities than by romance or family. Vermouth cannot be understood through an ordinary age and career history, while Bourbon constantly performs false roles for an undercover mission.
Their Infiltration and Intelligence Skills Work Well Together
Vermouth and Bourbon frequently work together because both are highly capable at infiltration and intelligence gathering.
Vermouth can approach a target as someone else through precise disguises and voice imitation. By passing as an investigator or an ordinary civilian, she can enter a social setting and collect information without exposing herself.
Bourbon is treated as an information specialist inside the Organization. He uses observation, deduction, and conversation to uncover what others are hiding. His ability to move among the identities of Tooru Amuro, Rei Furuya, and Bourbon makes him especially effective.
Vermouth gets close through appearance and voice; Bourbon probes through dialogue and inference. Together they are formidable in missions conducted within normal society. The Jet-Black Mystery Train, the Scarlet arc, and the movie Black Iron Submarine all illustrate that combination, although the last is movie-only evidence.
Compatible skills do not mean compatible goals. Vermouth has personal reasons to protect Conan and Ran, while Bourbon pursues the Organization as a Public Security Bureau operative. Even within the same operation, they may be looking toward different outcomes.
Their Bond Is Closer to Mutual Use and Deterrence Than Trust
Rather than trusting partners, Vermouth and Bourbon use each other’s abilities and restrain each other through secrets.
Vermouth benefits from Bourbon’s ability to gather intelligence, while Bourbon benefits from her disguises and her position within the Organization. At the same time, Bourbon knows a secret Vermouth is desperate to protect.
Vermouth clearly treats that knowledge as dangerous, but she cannot simply remove him without risk. Bourbon, meanwhile, also lives under threat because exposure of his Public Security Bureau identity could cost him his life.
For these two, learning more does not create intimacy; it creates greater caution. Their calm exchanges can carry an implicit threat, which gives their relationship more tension than a conventional romance would.
Bourbon Knows Vermouth’s Secret
The most important imbalance between them is that Bourbon knows a major secret about Vermouth.
His wording strongly implies—but does not confirm—that the secret concerns the Black Organization’s boss. He says Organization members would be surprised by it, but the precise content remains unrevealed. The implication is important; it is not a completed answer.
Vermouth is usually the person manipulating everyone around her. In this exchange, Bourbon possesses the information and reverses that balance of power.
The Scarlet Arc Hints at a Secret About “the Boss’s…”
Bourbon raises Vermouth’s secret after the Scarlet arc’s conflict over whether Shuichi Akai survived.
When Bourbon again seeks Vermouth’s cooperation, he uses his knowledge as leverage.
Bourbon says that he is one of the few people who knows her secret, that the Organization would be surprised, and then begins to say that she is “the boss’s…” before stopping. (unofficial translation)
This establishes that Bourbon counts himself among a small number of people who know the secret. His wording does not make him the only person who knows it. Others may know, but the information appears tightly restricted within the Organization.
The unfinished phrase connects the mystery to the boss without defining the relationship. Because the sentence stops at the decisive point, the story leaves both the nature of the secret and Vermouth’s exact connection to the boss unresolved.
Vermouth Reacts Strongly Enough to Point a Gun
Vermouth responds with immediate hostility when Bourbon approaches the subject of her secret.
She normally keeps her composure even in dangerous situations, teasing others and concealing her own reactions. When Bourbon begins the phrase about the boss, that composure gives way to open pressure.
Vermouth points a gun at Bourbon and warns him against disclosing what he knows. Her reaction shows that the information matters greatly to her, but it does not by itself reveal whether the secret concerns age, identity, family, status, or something else.
Bourbon is not relying on nerve alone. He indicates that he has arranged for the secret to reach the Organization if something happens to him. That insurance makes killing him dangerous for Vermouth.
Although Vermouth holds the weapon, Bourbon’s information gives him the stronger negotiating position. The scene captures their relationship in miniature: physical danger on one side and carefully protected leverage on the other.
What Follows “the Boss’s” Is Still Unknown
The missing words after Bourbon’s reference to “the boss’s…” have not been revealed in the evidence discussed here.
Readers can imagine possibilities such as daughter, wife, or mother, but those classifications are not confirmed here. Treating one as the answer would turn speculation into fact.
The evidence discussed here supports only several separate observations: Vermouth receives special treatment from the boss, her appearance has not changed for decades, and Bourbon knows a closely guarded secret that he links to the boss. These facts do not automatically establish a specific family relationship.
How Bourbon learned the secret is also unknown. The material does not resolve whether he discovered it through his own investigation, obtained it through the Public Security Bureau, or encountered it during a mission. His route to the information must therefore remain open.
Does Vermouth Know Bourbon’s Real Identity?
It appears likely that Vermouth does not know Bourbon is Rei Furuya of the Public Security Bureau, but the evidence discussed here does not settle the point conclusively.
Vermouth knows his public face as Tooru Amuro and his Organization codename, Bourbon. No provided scene explicitly shows her identifying the deeper undercover identity behind those names.
This creates a possible imbalance: Bourbon knows Vermouth’s most sensitive secret, while Vermouth may not know his. That uncertainty makes every exchange between them more dangerous.
No Confirmed Scene Shows Her Identifying Rei Furuya as Public Security
None of the scenes discussed here show Vermouth stating that Bourbon’s real name is Rei Furuya or that he is an undercover Public Security Bureau officer.
An undercover operative conceals a real affiliation while entering a hostile organization. Furuya operates as Bourbon in order to oppose the Black Organization from within.
Vermouth is perceptive and highly alert to secrets, so she may suspect that Bourbon has another agenda. Suspicion, however, is not the same as identifying his real name, agency, and mission. Those layers of knowledge should not be conflated.
If Vermouth ever learns his affiliation with certainty, Bourbon would face a potentially fatal threat. Whether she would report him or keep silent to protect her own secret is likewise unresolved.
Bourbon’s Private Investigation of Akai’s Survival
Bourbon questioned Shuichi Akai’s apparent death and independently investigated whether Akai had survived rather than immediately sharing every part of his reasoning.
Akai made the Black Organization believe he was dead and remained at the Kudo Residence as Subaru Okiya. Bourbon examined the circumstances surrounding Rikumichi Kusuda’s body and Raiha Pass as he moved closer to the survival theory.
He also used Vermouth’s disguise ability while testing his conclusions. Yet the evidence discussed here does not support saying that he disclosed his full reasoning and true objective to her from the outset.
In the Scarlet arc, the plan prepared by Yusaku Kudo, Conan, and Akai prevents Bourbon from obtaining the decisive proof he wants. His behavior still shows that he is not merely a loyal information gatherer following the Organization’s wishes.
Bourbon uses Vermouth’s help without giving her his entire inner purpose. He possesses her secret while protecting himself through lies of his own, so the roles of knower and known are never completely stable.
Scotch’s Death and Why Amuro Opposes the Organization
Scotch, Hiromitsu Morofushi, and his death are essential to understanding Bourbon’s true position.
Scotch was Furuya’s childhood friend and police academy classmate. Like Furuya, he infiltrated the Black Organization, but his Public Security identity was exposed and he died during the mission.
Furuya initially believed Shuichi Akai was responsible for Scotch’s death and carried intense resentment toward him. That history is explored in The Betrayal’s Stage.
For Furuya, the Black Organization is not a group of genuine comrades. Even when he works beside Vermouth, he remains an infiltrator acting against the organization from within.
Their occasional alignment is therefore better understood as overlapping interests than as romance or deep trust. Outwardly they are fellow members; underneath that appearance, Bourbon serves Public Security.
Examining the Romance, Marriage, and Family Theories
The available story material offers no evidence that Vermouth and Bourbon are lovers, spouses, or parent and child.
Rumors are easy to understand because they work together repeatedly and Vermouth often speaks with a suggestive confidence. Still, what binds them on the page is mission work, complementary ability, and dangerous information.
The physical closeness of an operation does not establish emotional intimacy. Their exchanges are marked by calculation and guarded intentions.
No Depiction Confirms Romance or a Sexual Relationship
There is no available depiction of romantic feelings or a sexual relationship between Vermouth and Bourbon.
Vermouth naturally speaks in ways that can make a conversation feel intimate. Bourbon also uses a gentle smile and polished manners to lower people’s guard while he searches for information.
Their shared scenes can therefore carry the atmosphere of two sophisticated adults. But their actual subjects are operations and intelligence, and Bourbon is willing to use Vermouth’s secret as leverage.
The dominant current between them is tension, not affection. Their physical proximity contrasts with emotional distance, and each must read past the other’s smile to find the hidden purpose underneath.
Elena Miyano and Japan Matter More to Tooru Amuro’s Character
Two major elements in Tooru Amuro and Rei Furuya’s emotional background are Elena Miyano, whom he knew in childhood, and the country he now works to protect.
Elena treated Furuya’s injuries when he was a child and showed him kindness. The evidence discussed here suggests that he may have felt an admiration resembling a first crush, but that interpretation should remain a possibility rather than a confirmed romantic classification.
Elena has died, and she should not be framed as Furuya’s present romantic partner. His current actions center on his duty as a Public Security Bureau officer.
In the movie Zero the Enforcer, Amuro calls Japan his lover. (unofficial translation) This is movie-only evidence and should not be used to rule out every possible romance in the broader story. It does, however, emphasize how strongly he places national duty at the center of his identity.
For an analysis of Vermouth and Bourbon, the safest conclusion is that Furuya’s mission takes precedence over an unsupported Organization romance. His emotional history reaches back to Elena’s kindness, while his present purpose leads him into enemy territory.
The Marriage and Parent-Child Theories Lack Story Evidence
No available scene confirms that Vermouth and Bourbon are married or related as parent and child.
Similarities in hair color, complexion, or overall appearance do not establish an in-story family connection. Neither do facts about the private lives of performers associated with the characters.
Vermouth has maintained an unchanged appearance for decades and performed the roles of both Sharon Vineyard and Sharon’s supposed daughter Chris. That unusual history makes ordinary age calculations unreliable and may encourage family theories.
No family information available for Bourbon or Rei Furuya connects him to Vermouth. Based on the evidence discussed here, their repeated pairing is adequately explained by their infiltration skills and Black Organization assignments.
The unusual part of their bond is not a hidden marriage or bloodline but how deeply each has entered the other’s world of secrets.
Key Stories Featuring Vermouth and Bourbon Together
The key viewing includes Detectives’ Nocturne, The Jet-Black Mystery Train, the Scarlet arc, The Betrayal’s Stage, and the movie Black Iron Submarine.
At first, Vermouth and Bourbon can look like ordinary colleagues within the same criminal organization. As the story advances, Vermouth’s personal aims, Bourbon’s Public Security role, and the leverage between them become increasingly visible.
- Detectives’ Nocturne: International episodes 723-726 (Japanese episodes 671-674)
- The Jet-Black Mystery Train: International episodes 753-756 (Japanese episodes 701-704)
- The Scarlet arc: International episodes 832-836 (Japanese episodes 779-783)
- The Betrayal’s Stage: International episodes 921-922 (Japanese episodes 866-867)
- Black Iron Submarine: Movie 26
Detectives’ Nocturne: The Bourbon Arc Moves Forward
Detectives’ Nocturne is the series in which the Bourbon arc begins to move decisively.
At this stage, the story encourages suspicion toward Tooru Amuro, Masumi Sera, and Subaru Okiya without immediately revealing which one is Bourbon. Each person’s behavior can be read as suspicious.
Vermouth is connected to Bourbon’s movements, showing that a new Black Organization investigator is operating behind the everyday case. Bourbon’s face and identity are not yet settled for the audience, so his exact relationship with Vermouth is still only an outline.
The arc’s shift from an ordinary incident to the Organization establishes the ominous information-sharing around the pair. It covers International episodes 723-726 (Japanese episodes 671-674), beginning with Detectives’ Nocturne (The Case) and ending with Detectives’ Nocturne (Bourbon).
The Jet-Black Mystery Train: Both Move Against Sherry
In The Jet-Black Mystery Train, Vermouth and Bourbon act around Sherry, Shiho Miyano, but their intended outcomes do not fully match.
Bourbon intends to bring the living Sherry back to the Organization, while Vermouth intends to eliminate her aboard the train. They pursue the same person without sharing an identical objective.
Vermouth also has personal reasons not to place Shinichi Kudo and Ran in danger, while Bourbon outwardly pursues Sherry as an Organization member. Their parallel but separate plans reveal how little of their true thinking they share.
Disguise, explosives, and competing hidden agendas make this the clearest collision of their abilities and secrecy. The story spans International episodes 753-756 (Japanese episodes 701-704), from The Jet-Black Mystery Train (Departure) through The Jet-Black Mystery Train (Destination).
The Scarlet Arc: Their Secret Bargaining Becomes Visible
In the Scarlet arc, Bourbon closes in on Shuichi Akai’s survival while Vermouth assists his operation.
Vermouth uses a disguise, while Bourbon analyzes Rikumichi Kusuda’s body and the deception at Raiha Pass in an attempt to expose Subaru Okiya. Their combined infiltration ability creates a serious threat to Conan and Akai.
Yusaku Kudo, Conan, and Akai counter the investigation, leaving Bourbon without the decisive proof he seeks. Afterward, Bourbon invokes Vermouth’s secret concerning “the boss’s…”
The transition is striking: during the operation they cooperate, and once it ends their exchange becomes one of threat and countermeasure. The arc runs through International episodes 832-836 (Japanese episodes 779-783), from The Scarlet Prologue to The Scarlet Truth.
The Betrayal’s Stage: Scotch’s Death and Bourbon’s Motives
The Betrayal’s Stage explores why Bourbon intensely resents Shuichi Akai and reveals the history surrounding Scotch’s death.
This is not primarily an episode about direct secret bargaining between Vermouth and Bourbon. It matters because it shows why Bourbon should not be understood as a man devoted to the Black Organization.
Scotch was a Public Security infiltrator and Rei Furuya’s childhood friend. The loss behind Bourbon’s Organization persona changes how his scenes beside Vermouth should be read.
Both characters hide their real intentions, but they do so from different positions. Vermouth remains tied to the Organization and her secret, while Bourbon entered it as an operative acting against it. The story appears in International episodes 921-922 (Japanese episodes 866-867): The Betrayal’s Stage (Part 1) and The Betrayal’s Stage (Part 2).
Black Iron Submarine: The Movie Reinforces Their Infiltration Partnership
In the movie Black Iron Submarine, Vermouth and Bourbon infiltrate Pacific Buoy as part of a Black Organization operation.
The film again pairs Vermouth’s disguises with Bourbon’s infiltration and intelligence skills. Pacific Buoy is an offshore facility connecting security-camera systems around the world. The Organization targets new facial-recognition technology, leading to the abduction of Naomi Argento and the struggle involving Ai Haibara.
Although the two participate in the same operation, Vermouth takes independent action and does not share everything with Gin and the others. Bourbon likewise retains a separate purpose as a Public Security operative.
This movie-only evidence supports the plausibility of their operational teamwork but does not confirm the unresolved secrets of the manga and anime canon. Their coordination is effective precisely because neither shows the Organization a completely honest face.
Conclusion
Vermouth and Bourbon are frequent Black Organization collaborators, not confirmed spouses, relatives, or lovers.
Their repeated joint appearances can make them seem close, but romance and blood relation are not what make the pairing interesting. Vermouth hides a secret connected in some unresolved way to the boss, while Bourbon hides his role as a Public Security Bureau officer opposing the Organization.
Bourbon knows enough about Vermouth to threaten disclosure, and Vermouth cannot remove him without risking that information’s release. Cooperation therefore never produces comfort. Their quiet dialogue can remain polite while each keeps a hand on the other’s vulnerability.
The Jet-Black Mystery Train shows their objectives diverging around the same target, while the Scarlet arc turns operational cooperation into explicit leverage. The more they work together, the more their hidden intentions matter.
The largest unresolved questions are the exact nature of Vermouth’s connection to the boss and whether she will ever identify Bourbon’s Public Security role. If either secret becomes public, the pair could be forced into a new alliance or open conflict.
Their bond is compelling because it is built on secrets rather than affection. Each shared mission brings them closer in practical terms while making genuine trust less likely.
