List of characters who know Conan's identity

Over the course of the series, 18 characters have come to know that Conan Edogawa is actually Shinichi Kudo (8 of which are not manga canon). In addition, Ran Mouri has noticed similarities between the two and Kogoro Mouri and Wataru Takagi have shown signs of doubting that Conan is just "very smart".

In their respective categories, characters are listed by the order they came to discover (or become suspicious of) Conan's identity.

Canon

So far ten people have learned Conan's true identity is Shinichi in the manga canon. Four were told the truth and the other six discovered it for themselves.

Hiroshi Agasa

Professor Agasa found out that in Volume 1, at the second chapter of the series. Shrunken Shinichi had to persuade Agasa that the child before him is Shinichi so that he could seek help.

Akemi Miyano (Deceased)

Akemi Miyano, Ai Haibara's elder sister. Conan told her his real name as Akemi was dying.

The Kudo Couple

The Kudo couple, Shinichi's parents, Yusaku and Yukiko, heard that from Professor Agasa in Volume 6, after finding the Kudo household empty.

Heiji Hattori

Heiji Hattori found out this fact in Volume 13 (Holmes Freak Murder Case), as he found Conan speaking in Heiji's voice after Heiji regained consciousness from Conan's stun gun.

Ai Haibara

Ai Haibara's deduction of that was mentioned in Volume 18, after knowing Shinichi's clothes from his childhood had somehow disappeared from his house and that APTX4869 had de-aged one mouse during trials.

Vermouth

Vermouth realized similarities between Shinichi (when he was young) and Conan. She also chose not to betray Shinichi to the Black Organization, most likely because he and Ran saved her when she was disguised as a serial killer in New York.

Eisuke Hondou

Eisuke Hondou found out in Volume 60, after finding Conan's actions towards Ran as too similar to that of a boyfriend. Also, it appears as if he knew since the first time he met Conan, as at the time he purposely fell into Conan, knocking off his glasses. Then acting as if he couldn't see, he called Conan, Detective Mouri.

Subaru Okiya/Shuichi Akai

Subaru Okiya (Revealed to be Shuichi Akai at the end of File 824) was confirmed to know Conan's identity when he caught Conan pretending to be Shinichi over the phone. Based on some of the questions he asked Ran, he may have deduced Conan was Shinichi much earlier, but had lacked absolute proof up until the phone incident.

Masumi Sera

Sera seems to have known Conan was Shinichi before they first met recently. Masumi remembers Shinichi from some meeting they had in the past and has been since trying to encourage Conan to remember where he met her. In "Conan vs. Heiji, Deduction Battle Between the Detectives of the East and West" episode, it's confirmed that Sera knows when she thinks "Now we already know who's the winner" while looking towards Conan that thinking about the case, referring him as "Shinichi".

Non-Canon

Kaitou Kid

Kaitou Kid (also known as Phantom Thief Kid) becomes aware of Conan's true identity in The Last Wizard of the Century. While disguised as Ninzaburo Shiratori, Kid had bugged the phones on the Suzuki Financial Group's ship and therefore heard all of the conversation between Conan and Agasa on the phone. Not realizing they were being listened to, Agasa continued to refer to Conan as "Shinichi" on the phone as he normally does. It is assumed that afterwards Kid put two and two together. Kid's knowledge of Conan being Shinichi is confirmed in The Lost Ship in the Sky. Kid's knowledge of Conan's identity has not been stated in the manga and has not been confirmed by Gosho Aoyama to be canon, although in the manga Kid is definitely aware that Conan is no mere child.

Hiroki Sawada (Deceased)

Hiroki Sawada in The Phantom of Baker Street; how he knew that was not given, though it was most likely through the DNA Query Program.

Hajime Kindaichi

Lupin III Cast

In the TV Special Lupin III vs. Detective Conan, the famous gentleman thief named Lupin III and his associates Jigen, Fujiko, and Goemon, through some means discover Conan's true identity and help him sneak back into Japan after traveling to the country Vespania (Conan would've needed a passport to return home, but his passport was for Shinichi Kudo).

Irish (Deceased)

In the 13th movie, The Raven Chaser, Black Organization member Irish discovers Conan's secret identity. However, instead of revealing it to the Organization, he decides to use that to gain more power with the boss, because of an old grudge he has with Gin for killing Pisco, his mentor, without orders to do so. He is shot to death by Chianti before he can do anything.

Suspicious

Although several characters have caught on to the fact that Conan is much smarter than most children, only a few characters have questioned exactly why he is so smart. Although the FBI are aware of Conan's intelligence and even talk to him like he is an adult (Shuichi Akai), they do not seem to be too concerned about how he got so smart, especially since they have not encountered Conan's true self, Shinichi Kudo. Some of the police like Miwako Sato and Ninzaburo Shiratori take Conan's deductions seriously, but like the FBI, they seem to believe he is just an exceptionally bright child.

Kogoro Mouri

Kogoro was the first character to become suspicious of Conan's identity, albeit briefly. In Volume 2, he felt like he had seen Conan from somewhere before, likely the time when Ran was in elementary school. Later, he noticed that Conan was once again pointing out things he overlooked, such as that all of the photos proving the suspects alibi had clocks in them. However, he instantly loses his suspicions when Conan spills another envelope of photos for the case, deciding that "a brat is a brat" after all.

In the TV Station Murder Case, Kogoro became suspicious about Conan for the second time. He was invited to attend a television live show as a guest star. However, a murder occurred at the studio. After finding out all the evidences, Conan lured Kogoro to a separate room, lying that Yoko Okino was in there. Just as usual, he decided to tranquilize Kogoro and used the man to solve the case. Unfortunately, when Kogoro woke up, he began to question Conan about Yoko's whereabouts. He was also suspicious about the fact that whenever Conan tried to pull him outside, he always fell asleep right after. Kogoro angrily grabbed the boy's suit jacket and wanted to "clear things up". Much to Conan's luck, Yoko Okino appeared for real and Kogoro completely lost his suspicions.

Ran Mouri

Ran suspecting Conan is Shinichi.

Ran has on more than one occasion noticed the striking similarities between him and Conan; being his childhood friend and one of the people that know Shinichi the best, She first becomes suspicious during the Episode 7: Once-A-Month Present Threat Case and even tricks him into answering to "Shinichi", however, like her father, she is easily convinced she was wrong when he begins playing with the box of toys. In Episode 96, she sees Conan without his glasses and notices he looks exactly the same as Shinichi when he was a child. She even tries to confront him about it, but Yukiko then arrives and claims that Conan is her distant nephew. Later on, in The Desperate Revival, it is revealed that Ran believes Conan is Shinichi and is waiting for him to tell her. She is only dissuaded from this when Shinichi appears at the same time that Conan does. It turns out that Haibara has given Conan a temporary antidote that will return him to Kudo Shinichi and disguised herself as Conan. After a text message she sends to Shinichi is received on Conan's cell phone her suspicions are aroused again, but Conan uses Agasa's cell phone to call her as Shinichi and messages her his "new" cell phone number. Since then, Ran has apparently been too happy with having Shinichi's "secret number" to become suspicious of Conan. An upcoming suspicion arc has been foreshadowed with Heiji Hattori's omamori and her wondering how Shinichi's fingerprints got on it when only Conan has touched it, coupled with Conan's recent lack of subtlety.

Wataru Takagi

When it seemed they would both die while disarming a bomb, Detective Takagi agreed to follow Conan's instructions in exchange for telling him who he really is. Conan agreed but said he would tell him in the afterlife. Takagi had also thought to himself that Conan was not just any normal kid prior to this, but he has not made this observation since nor has he asked Conan to explain his answer. It is worth noting however that Takagi is aware of Conan's Stun-Gun Wristwatch and will do nearly anything Conan asks him to do, including dressing up as a mailman in order to fool some kidnappers. Also, in a recent case Takagi refers to Kudo as "Shinichi-kun", something that is strange considering that the last contact Shinichi and Takagi had (Shiragami case) he still called him "Kudo-kun".

Tooru Amuro/Bourbon

Amuro suspects Conan is creating the Sleeping Kogoro, but it is unclear if he has any suspicions about Conan's identity or relationship to Shinichi.
