What was the relationship between Elena Miyano and Tooru Amuro?
Was Elena Amuro’s first love?
Tooru Amuro is Rei Furuya of the Public Security Bureau, working undercover in the Black Organization as Bourbon. One person at the roots of his story is Ai Haibara’s mother, Elena Miyano.
Elena and the young Rei had a doctor-and-patient relationship. Rei repeatedly visited the Miyano Clinic, sometimes deliberately getting hurt because he wanted to see her.
Elena was Rei’s childhood first love, and his search for the woman who disappeared became one reason he wanted to join the police.
The kind doctor who treated Rei later became a Black Organization scientist known as Hell Angel, while the boy eventually entered that organization as the undercover agent Bourbon. The contrast between their warm past and cold present makes their connection especially painful.
This article examines Elena’s relationship with Rei, the first-love implication, his reason for becoming a police officer, the relevant manga and anime stories, and his connections to Akemi Miyano and Shiho Miyano.
Elena Miyano and Tooru Amuro Were Doctor and Patient

Elena Miyano was a doctor at the Miyano Clinic, and Rei Furuya was one of the children she treated. At that time, he had not yet adopted the name Tooru Amuro. Elena knew him simply as young Rei.
Rei often fought after being mocked for his appearance. Those fights brought him to the clinic, but medical care was not always his only purpose: he sometimes made sure he had an injury so that he could see Elena again.
Although their formal relationship was doctor and patient, Elena was also an adult who accepted Rei’s appearance and feelings instead of rejecting them. That made her far more than the person who put bandages on his wounds.
Young Rei Furuya Kept Visiting the Miyano Clinic
Young Rei visited the Miyano Clinic repeatedly for treatment. Elena worked there with her husband, Atsushi Miyano, and Akemi once brought the injured Rei to the clinic. This establishes that he had contact with the Miyano family during childhood, not only with Elena in isolation.
His repeated injuries were not all accidental results of fighting. He also hurt himself so Elena would treat him and speak with him. The behavior was dangerous, but it shows how safe and welcome he felt in her presence.
The clinic may have been one of the few places where a boy mocked for his looks felt accepted exactly as he was. That unguarded childhood feels particularly warm when compared with the adult Rei, who must constantly divide himself among multiple names and roles.
Elena Miyano Was Rei Furuya’s First Love
Elena was Rei’s first love. Although the main manga does not have him state the phrase directly, the police academy story and the surrounding context establish that the older woman he was seeking was Elena.
His feelings for Elena are strongly implied to have been special, based on his willingness to get hurt just to see her and the vivid memory he retains as an adult. This was not an adult romance. It was the tender admiration of a child for a beautiful, kind doctor who protected and affirmed him.
That admiration also overlapped with gratitude toward an adult who understood him. The later irony is bitter: his childhood love became a scientist in the Black Organization, and he eventually infiltrated the same group as Bourbon.
Elena Became an Ally Against Prejudice About His Appearance
Elena mattered to Rei for more than medical treatment. When he was hurt after being mocked for his hair and skin color, she rejected the prejudice behind the conflict while still discouraging him from fighting.
“Black people, white people, and Asian people all have the same red blood flowing through them. Tell them that.” — Elena Miyano (unofficial translation)
“But if it is an honorable wound from making up with the person you fought, I can at least put a bandage on it.” — Elena Miyano (unofficial translation)
Elena clearly refused to divide people’s worth by race or appearance. Rather than merely ordering Rei not to fight, she understood why he was angry and offered him another way to answer prejudice and reconcile with the other child.
For someone who would later live behind the names Tooru Amuro, Rei Furuya, and Bourbon, Elena’s insistence on a shared human core carries unusual weight. She treated both the visible injury and the hurt underneath it.
Manga and Anime Stories That Reveal Elena and Amuro’s Connection

The complete connection between Elena and Rei was not disclosed in a single story. Volume 84, File 889, first showed an unidentified woman in a white coat calling him “Rei.” Volume 95 later identified her as Elena and connected the memory to the Miyano Clinic.
- Volume 84, File 889, “Zero”; Episode 824 (Japanese episode 771), “The Tense Tea Party (Part 2)”
- Volume 95, Files 1010-1011; Episodes 1010-1011 (Japanese episodes 953-954), “The Unsolved Cocktail Case (Part Two)” and “The Unsolved Cocktail Case (Part Three)”
- Police Academy Arc, CASE: Rei Furuya
A brief clue about Amuro’s real name gradually expands into a story about childhood affection, the Miyano family, the Karasuma Group, and his reason for entering police work.
Volume 84, File 889 and Episode 824 Reveal the Name “Rei”
The first direct hint appears in Volume 84, File 889, “Zero,” adapted as Episode 824 (Japanese episode 771), “The Tense Tea Party (Part 2).” During the case at Haido Central Hospital, Amuro remembers being treated as a child by a woman in a white coat. Her identity and connection to the Miyano family remain unstated at that point.
The woman calls him Rei and tells him she is going far away.
“I told you not to fight again. Even if you come back hurt, I will not be able to treat you, because I am going far away.” — Elena Miyano (unofficial translation)
“I guess this is goodbye, Rei.” — Elena Miyano (unofficial translation)
On its first appearance, the memory works as a clue to Amuro’s real name and proves that the woman knew him in childhood. After the later revelations, it also becomes the memory of a child losing an important person without understanding where she was going.
Volume 95, Files 1010-1011 and Episodes 1010-1011 Connect the Past
Volume 95 explicitly connects the woman in the white coat to Elena Miyano. The relevant chapters are Files 1010 and 1011, adapted as Episodes 1010-1011 (Japanese episodes 953-954), “The Unsolved Cocktail Case (Part Two)” and “The Unsolved Cocktail Case (Part Three).”
Hearing a reference to an injury brings back Amuro’s memories of visiting the clinic. The flashback reveals that he deliberately got hurt to see Elena. Elena is pregnant with Shiho at the time, while she and Atsushi discuss moving to a research facility.
The unidentified doctor from Volume 84 is now connected to three distinct roles: Ai Haibara’s mother, a future Black Organization scientist, and Rei’s first love. These roles converge in one quiet memory of the clinic.
CASE: Rei Furuya Explains One Reason He Wanted to Be a Police Officer
The police academy story reveals that Rei’s decision to become a police officer was connected to a woman who had suddenly disappeared. He tells Jinpei Matsuda that he is looking for her. Although he does not name Elena in that conversation, the clinic memories make her the strongly implied person.
From the child’s perspective, Elena simply went far away without explaining her destination. Police work offered a path toward finding the truth. The manga strongly implies that searching for Elena was one starting point for his police career; it does not establish that she explains every later choice.
Nothing in the story establishes that Elena alone caused his assignment to the Public Security Bureau or his infiltration of the Black Organization. His friendships and losses after entering the police also shaped the adult Rei.
Why Did Elena Miyano Disappear from Amuro’s Life?

Elena disappeared from young Rei’s life because she and Atsushi decided to leave the Miyano Clinic and move to a research facility. The research was backed by the Karasuma Group, placing the family on a path that would later connect them deeply to the Black Organization.
That does not establish that the couple knowingly chose criminal research from the outset. Atsushi was offered support and a place where he could continue work that others had not accepted.
Atsushi Miyano Accepted Support from the Karasuma Group
The immediate reason Elena left the clinic was an invitation to a facility that would support Atsushi’s research. His work was poorly understood, and the offer promised both a research environment and funding. Elena was pregnant with their second child, so the family was considering a major change in both work and home life.
The sponsor was identified as the Karasuma Group, a name that connects, from the later perspective of the story, to Renya Karasuma and the Black Organization. What looked like a hopeful professional opportunity therefore takes on a threatening meaning for readers.
The story does not establish how much Elena and Atsushi understood about the sponsor’s hidden side when they accepted the move. It would go beyond the evidence to claim that they already knew the organization’s full nature or deliberately entered criminal research.
Elena Cannot Be Treated as the Sole Reason for Rei’s Undercover Career
Rei’s wish to find Elena helped lead him toward police work. However, the story does not say that Elena alone explains his later entry into the Public Security Bureau or his infiltration as Bourbon.
At the police academy he met Jinpei Matsuda, Kenji Hagiwara, Wataru Date, and Hiromitsu Morofushi. Those friendships, his competition with them, and later experiences all contributed to the convictions he displays as an adult.
Elena is best understood as one of Rei Furuya’s origins, while the road to Public Security and his Bourbon identity grew through events that followed. The story contains no statement that he infiltrated the organization specifically to reach Elena.

How Much Does Amuro Know About Elena Miyano?

Amuro knows that Elena became the Black Organization scientist called Hell Angel and that she was the mother of Shiho Miyano, code-named Sherry. It is not established that he knows the full details of APTX 4869, its de-aging effect, or the circumstances of the laboratory fire.
The child Rei knew a gentle doctor; Bourbon later knew information about a feared scientist. Those two layers of knowledge concern the same woman, but they should not be expanded into knowledge of every part of her work or death.
He Knows the Codename “Hell Angel”
Bourbon knows that Elena was called Hell Angel within the Black Organization. During the Mystery Train confrontation, he addresses the apparent Shiho as Hell Angel’s daughter. That wording shows knowledge of Elena’s alias and her parent-child relationship with Sherry.
For Rei, the kind doctor at the Miyano Clinic and the scientist known as Hell Angel had already become the same person. The story does not show when or through which assignment he learned this.
It is possible that he found traces of the woman he had sought inside the organization he infiltrated, but the story does not confirm that sequence. The contrast alone is painful: the doctor he remembered warmly carried a frightening organizational epithet.
His Knowledge of APTX 4869 and Elena’s Death Is Unclear
Knowing Elena’s alias does not mean Amuro knows everything about her research. Elena participated in the organization’s work and referred to APTX 4869 as the Silver Bullet, but the story contains no scene showing Amuro’s detailed understanding of the research or the drug’s effects.
An undercover operative is not automatically given every secret held by a compartmentalized organization. The research division and field operatives may have access to different information.
It is also unclear when Amuro learned that Elena and Atsushi died in a laboratory fire or whether he knows the full circumstances. The secure conclusion is limited to his knowledge that Elena became an organization scientist and was Sherry’s mother.
Amuro’s Connections to Akemi Miyano and Shiho Miyano

Rei met Akemi as a child, but he did not meet her younger sister Shiho during that period. Although Bourbon appears to confront Shiho on the Mystery Train, the person before him is actually Kaitou Kid in disguise.
It is not confirmed in the evidence discussed here that Amuro knows the present-day Ai Haibara is Shiho Miyano. Familiarity with members of the Miyano family and knowledge of Haibara’s identity are separate claims.
He Knew Akemi Miyano in Childhood
Rei and Akemi met during the Miyano Clinic period. Young Akemi brought the injured Rei to the clinic, where Elena treated him. This shows that Rei entered the Miyano family’s everyday circle and did not know Elena only through isolated appointments.
Akemi’s act also reflects the kindness later associated with her care for Shiho. However, the story does not establish whether Rei met Akemi again as an adult or recognized her within the Black Organization. Their childhood encounter and any later relationship must remain separate.
The “Shiho” on the Mystery Train Was Kaitou Kid in Disguise
Bourbon believed he was confronting Shiho Miyano on the Mystery Train, but he was actually speaking to Kaitou Kid in disguise. The organization believed Sherry had survived, and Conan’s side used the disguise to protect Haibara.
“As expected of Hell Angel’s daughter. You look very much like her. It is a pleasure to meet you. Bourbon—that is my codename.” — Bourbon (unofficial translation)
Bourbon’s “pleasure to meet you” indicates that he had not previously met Shiho herself. He knew Elena, Atsushi, and Akemi, but the family had disappeared from his life before Shiho grew up.
This encounter cannot establish any exchange of secrets between Amuro and Haibara. Amuro thought he was addressing Shiho, but the actual listener was Kaitou Kid.
Confirmed Childhood Acquaintances Are Elena, Atsushi, and Akemi
The Miyano family members Rei is confirmed to have met are Elena, Atsushi, and Akemi. Bourbon also tells the apparent Shiho that he has met her parents and sister.
“I have met your parents and your sister.” — Bourbon (unofficial translation)
Combined with his introduction immediately beforehand, the statement distinguishes those three acquaintances from Shiho. It would therefore be inaccurate to say that Amuro had always known every member of the Miyano family.
The emotional tension is still considerable: as Bourbon, he attempted to return the daughter of the family who had once cared for him to the organization. His complete private intent in that moment is not established by the evidence discussed here.
There Is No Confirmation That Amuro Knows Haibara Is Shiho
No scene confirms that Tooru Amuro identifies Ai Haibara as Shiho Miyano. On the Mystery Train, Bourbon was led to believe Sherry died in the explosion, and no later scene shows him learning that she survived.
In Volumes 101-102, “Takagi and Date and the Notebook Promise,” Amuro and Haibara occupy the same space at Café Poirot. The anime adaptation is Episodes 1167-1168 (Japanese episodes 1109-1110), “Takagi and Date and the Notebook Promise (Part 1)” and “Takagi and Date and the Notebook Promise (Part 2).”
His look can seem suggestive, but he never states that he recognizes her as Shiho. The story does not resolve whether he notices a resemblance to Elena or is watching her for another reason. Suggestive attention is not the same as confirmed knowledge of her identity.
The movie Black Iron Submarine raises suspicion within the organization about Haibara and Shiho being the same person, but the evidence discussed here does not give Amuro a clear moment of recognition there. His knowledge remains unconfirmed, and the movie-only suspicion must not be treated as proof that he knows.
Nor can the story establish that he protects Haibara specifically because of Elena. His actions combine his Public Security duties, the Bourbon role, and his dealings with Conan. A future conversation about Elena could finally join their histories, but whether that will happen remains unknown.

Conclusion
Elena Miyano and Rei Furuya began as doctor and patient at the Miyano Clinic.
- Elena treated young Rei at the Miyano Clinic.
- Rei sometimes got hurt deliberately so he could see her.
- Elena was his childhood first love.
- She defended him against prejudice about his appearance.
- She left when the family moved to a Karasuma Group-backed research facility.
- Searching for her is strongly implied to be one reason Rei wanted to become a police officer.
- The story does not make her the sole reason for his Public Security or undercover career.
- Amuro knows Elena was Hell Angel and Sherry’s mother.
- His knowledge of APTX 4869 and the laboratory fire remains unclear.
- He met Akemi in childhood.
- He had not previously met Shiho herself.
- The Shiho he confronted on the Mystery Train was Kaitou Kid in disguise.
- It is not confirmed that he knows Haibara is Shiho.
The clinic scenes preserve a gentle memory of an injured child and the doctor who accepted him. Yet Elena later became Hell Angel, while Rei entered the organization as Bourbon on behalf of the Public Security Bureau. The distance between that peaceful clinic and their later roles gives the relationship its lasting bitterness.
What first seemed like a clue contained in the name “Rei” eventually connected childhood affection, separation, the Miyano family, and the Karasuma Group. The unfolding meaning of that brief memory is one of the strongest features of this storyline.
Rei, who once searched for Elena, now stands close to Elena’s surviving daughter without a confirmed shared understanding of their connection. Elena is both one origin of Rei Furuya’s path and an unresolved bridge between Amuro and Ai Haibara.
