!!Sumiko Kobayashi
->''Voiced by Creator/YukoKobayashi / Yuko Kato (JP), Creator/StephanieYoung (EN)''

Conan and the Detective Boys' class teacher who later appoints herself as their "manager" when they're out solving cases.

[[spoiler:She later becomes Inspector Shiratori's girlfriend on account of him remembering that she was the girl he had helped in the past and not the physically similar Sato, whom he had been chasing after originally.]]

* {{Adorkable}}: Mostly when she acts as the "manager" of the Detective Boys or when she's with [[spoiler:her boyfriend, Shiratori, who slips into borderline {{adorkable}} status around ''her'']].
* BewareTheNiceOnes: A rare emotional example. When she thought that [[spoiler:Shiratori was only with her because of her strong resemblance to Detective Satou, she remained cold and took quite the distance towards him until she remembered him as the boy who helped her.]]
** Even before that there's her whole SadistTeacher act, which worked so well that only the kids stepping into her rehearsals could undo it.
* ChildhoodFriendRomance: With [[spoiler:Shiratori]]. It's also rather curiously played with: [[spoiler: They met as children, yes, but unlike the other "childhood couples" they didn't know each other's names and lost sight of each other for ''decades'' after their chance encounter. When they found each other, they weren't exactly the same persons they used to be (he was quite more prideful, she was more shy and quiet), he had chased after another woman for a long time [[LovingAShadow believing that she was Kobayashi]], and [[ForgottenFirstMeeting she couldn't remember him]]. [[FirstGirlAfterAll He still recognized her as the "destiny girl"]], she later recalled him, and then they got together.]]
* CoolTeacher: After her first episode.
* CurtainsMatchTheWindows: Her "after" appearance has her with matching black-blue hair and blue eyes, rather than her original light brown hair/black eyes looks.
* FanGirl: Of Ranpo Edogawa
* FriendToAllChildren: Even with her SadistTeacher act, she was only doing it for the children's sake. After she drops it, she plays the trope completely straight and all the kids adore her.
* FriendToAllLivingThings: During her SadistTeacher act, Kobayashi took care of the plants and fish in secret. Ayumi once caught her doing so.
* GirlyGirl: [[TomboyAndGirlyGirl Towards]] Sato's {{tomboy}}. Rather eagerly lampshaded by Yumi when they meet and she mistakes her for Sato, then is surprised by "Miwako"'s meekness.
* HiddenDepths: A retroactive example. [[spoiler:In Shiratori's flashback to when he first met Kobayashi-sensei, notice how Kobayashi-sensei is acting more assertive when she catches the two '''grown up''' thieves.]]
* HotTeacher: More of a [[{{Moe}} cute one]], though.
* IdenticalStranger: Without her glasses, Kobayashi looks a LOT like Detective Sato. [[spoiler: Which troubles her when Shiratori shows interest in her, as she believes at first he [[LovingAShadow only likes her because of her physical similarity to her]]. (Not to mention, the reason why Shiratori mistook Sato as the girl he liked was ''because'' of her looks.)]]
* ManicPixieDreamGirl: [[spoiler: Subverted: She was this [[SavvyGuyEnergeticGirl to Shiratori]], but only when they were children. When they meet again as adults and properly get together, she has grown into a more shy and thoughtful person.]]
* {{Meganekko}}
* [[NiceGirl Nice Woman]]: One of the friendliest people you'll meet in the series.
* OfficialCouple: With [[spoiler:Shiratori]].
* {{Otaku}}: Of mystery novels.
* PetTheDog: Even when she was making herself pass as a SadistTeacher, Kobayashi couldn't fully hide her kind nature, thus she watered the plants and fed the pet fishes in secret.
* RescueRomance: With [[spoiler:Shiratori, since she was the girl he rescued and admired long time ago.]]
* SadistTeacher[=/=]ToughLove: Her JerkAssFacade. For the reason, see the ShrinkingViolet section.
* {{Sensei chan}}: Downplayed, she only shows traits of the trope when she tries to be the manager of the Detective Kids but otherwise she's pretty competent and serious in her job [[spoiler: and since she has a boyfriend, there's nothing to worry in regards to the ChristmasCake part.]]
* SingleWomanSeeksGoodMan: She was at first attracted to [[spoiler: Shiratori]] for his gentlemanly behavior, but what made her ''actually'' fall in love with him was [[spoiler: seeing [[LawfulGood him]] deal a TheReasonYouSuckSpeech to the guy who [[HeKnowsTooMuch tried to silence her]], which let her remember how he protected her as children in a very similar way ''and'' dispelled the belief that he was using her to forget about Sato.]]
* ShrinkingViolet: After some really bad experiences in her former workplace, Kobayashi was so terrified of doing badly in parent meetings that she used to practice in the empty school at night with dolls. The Detective Kids thought she was a witch, though. (And Conan thought she was planning to kill someone else!).
* {{Tsundere}}: Type B. See her BewareTheNiceOnes section.

[[folder:Dr. Tomoaki Araide]]
!!Dr. Tomoaki Araide
->''Voiced by Creator/HideyukiHori (JP)''

The handsome son of Kogoro's doctor, with the bad luck of being introduced [[spoiler: in the case where his dad was murdered.]] After that, he's been seen around more than once, acting nice to almost everyone and being a possible RomanticRunnerUp.

[[spoiler:Later on, it's discovered that the Black Organization member, Vermouth, had been using his image as a cover during her manhunt for Ai Haibara.]]

* [[UglyGuysHotDaughter The Average-looking Doctor's Hot Son]]: His dad wasn't a {{Gonk}}, but it's clear that the younger Araide didn't inherit ''his'' looks.
* [[spoiler: GambitPileup]]: In the middle of ''two'' of these. See the main page for more details.
* HospitalHottie
* KindHeartedcatLover
* NiceGuy: Even veering into a male {{Ingenue}} of sorts, since he's way too gullible sometimes.
* RomanticFalseLead: Was presented as one, thought he's much nicer than the standard. [[spoiler: And Ran was more interested in his sweater.]]
* RomanticRunnerUp: Sorry, dude. You're nice and all, we all know it... but you're just not Shinichi. [[spoiler: He doesn't win even in the ''Stranger from Ten Years Later'' OAV, no matter if it's canon or not.]]
* StoicSpectacles: Subverted, he's more of a NiceGuy than TheStoic
* SympathyForTheDevil: When he returns to his normal life after [[spoiler: Vermouth]] tried to kill him and took over his identity for a while, most people don't notice a difference and comment on what a good person he is. This causes him to wonder whether his impostor is really evil.

[[folder:Eisuke Hondou]]
!!Eisuke Hondou
->''Voiced by Creator/JunkoNoda (JP)''

A NewTransferStudent to Sonoko and Ran's class who has a somewhat weak health and comes off to be extremely clumsy. He came to Japan to find his sister's whereabouts, [[spoiler: that sister being Hidemi Hondou of the CIA, aka, Kir of the Black Organization.]] He returned home shortly after the discovery, [[spoiler: but not before telling Conan that he knew of his true identity, and that he had developed feelings for Ran.]]

[[ThemeNaming Mandatory naming note]]: "Hondou" comes from Bondo (ボンド), the Japanese pronounciation of [[Film/JamesBond (James) Bond]], Eisuke from mystery writer Eisuke Kaito.

* [[spoiler:BigSisterWorship:]] To [[spoiler: Hidemi]]. As seen in [[spoiler: their flashback, Hidemi]] has saved Eisuke's life several times, includes [[spoiler: giving a large portion of blood donation to him,]] which later becomes one of plot points that [[spoiler: Rena Mizunashi]] is really Eisuke's [[spoiler:sister, Hidemi.]]
* ButtMonkey: Always falling on his face.
* CuteClumsyGirl: A RareMaleExample.
** [[spoiler: ObfuscatingStupidity: Though he ''is'' clumsy by nature, more than one of his blunders weren't that casual.]]
* DudeLooksLikeALady: And how-- go back above and check Kobayashi-sensei's picture, and he looks 80% like her.
* IllBoy: He had leukemia when he was a child, and he got better due to his older sister Hidemi's bone marrow donation. [[spoiler:This is a plot point as his blood type changed because of it: he used to be a O, but now he ''and'' Hidemi/Rena are AB.]]
** ''All'' story arcs related to him happened in hospitals. ''Even'' when he's not the one admitted.
* KansaiRegionalAccent: He was born and raised in Osaka
* LoveAtFirstSight: [[spoiler:Tells Conan that he fell in love with Ran the first time he met her.]]
* LoveTriangle: [[spoiler: Invoked and subverted. In front of Conan, Eisuke claims to have fallen in love with Ran and that he wants to take her to America with him. When [[CrazyJealousGuy Conan/Shinichi reacts strongly]], he takes it as ''the'' hint he needed to guess his secret identity, and then both promises to be one of his {{Secret Keeper}}s and [[IWantMyBelovedtoBeHappy asks him to protect her in his stead]].]]
* MasculineGirlFeminineBoy: with [[spoiler: his older sister Hidemi. Hidemi / Rena]] is ActionGirl, [[spoiler:TheMole, a CIA agent who infiltrate Black Organization.]] Eisuke is [[CuteClumsyGirl cute clumsy]] DudeLooksLikeALady.
* {{Meganekko}}: RareMaleExample; he has such a high {{moe}} quotient and girlish looks that he could easily pass as a female example.
* NewTransferStudent
* NiceGuy: He's polite, kind, and sensitive.
* SecretKeeper: One of the ''few'' people who actually ''guessed'' Conan's secret identity correctly, and ''by himself''. This probably put his intelligence on par with Heiji!
* SmartPeopleWearGlasses: Eisuke was able to guess that Conan '''is''' Shinichi Kudo simply by looking at him and then [[spoiler:pretend he was going to take Ran to America with him, so he could get a response from him]]. It worked!
* StrongFamilyResemblance: With his older sister, [[spoiler: Hidemi Hondou aka Rena Mizunashi aka Kir.]] Unknowingly lampshaded by Ran, who notices how the NewTransferStudent looks a ''lot'' like [[spoiler: Rena Mizuhashi herself]]...

[[folder:Subaru Okiya]]

[[folder:Masumi Sera]]
!!Masumi Sera
->''Voiced by Creator/NorikoHidaka (JP)''

A rather peculiar NewTransferStudent to Ran and Sonoko's class. Like Shinichi and Heiji, she is a high-school detective.

[[spoiler: She moved from the United States to Japan to find out what happened to her brother, Shuuichi Akai, after getting word of his supposed death.]]

[[ThemeNaming Mandatory Naming Note]]: Her name comes from ''Anime/MobileSuitGundam'''s Sayla Mass. [[spoiler:The family connections are not coincidental.]]

* ActionGirl: Jeet Kune Do practitioner
* ACupAngst: "They're due to pop out every day now!", and mentioning that her mother seems to have quite large breasts so hers will become this too.
* AmateurSleuth: Another high-school age detective.
* AmbiguouslyBi: Maybe, she ''did'' tease Ran and Sonoko by saying Ran's just her type.
* BadassBiker[=/=]BikerBabe: Uses a motorcycle most of time, and once used it to '''smack''' a criminal about to kill Conan.
* {{Bifauxnen}}[=/=]LadyLooksLikeADude: Treads the line between both tropes. She's an AmateurSleuth who at first is mistaken as a TroubledButCute guy until she shows up in Ran and Sonoko's class wearing the school's female uniform. In-story she's mostly seen as a tomboyish BikerBabe, and at least one of her friends (Sonoko) has found her pretty in a boyish way.
* {{Expy}}: Of ''another'' ''Conan'' character, [[Characters/DetectiveConanOneSceneWonders Natsuki Koshimizu]].
* FedoraOfAsskicking
* GreenEyes
* MessyHair: Part of her {{Bifauxnen}} appearance.
* [[NiceHat Nice Hats]]: Has a number of Fedoras.
* PantyShot: [[http://www.detectiveconanworld.com/wiki/images/6/63/Sera_slide_kick.png While bringing down someone]].
* RunningGag: About the above, people being unsure if she's a girl or a boy.
* SamusIsAGirl: On Ran, Conan and Sonoko.
* ShesGotLegs: See PantyShot.
* {{Shotacon}}: Sonoko thinks that this is why she's so fond of Conan.
* [[spoiler: StrongFamilyResemblance: As of Chapter 822, she's been revealed to be Shuuichi Akai's younger sister. Lampshaded by the fact that Conan mentions that she looks like someone he knows when they first met.]]
* {{Tomboy}}: When she said she was going to dress more girlishly for an ''IronChef''-style show's taping she meant she'd be wearing ''girly panties''.

[[folder:Tooru Amuro]]
!!Tooru Amuro[[spoiler:/Rei Furuya]]
->''Voiced by Creator/ToruFuruya (JP)''

A PrivateDetective who first appeared posing as a waiter while helping a client with a case. He currently works at Café Poirot, and has become Kogoro's apprentice.

[[spoiler:He is, in fact, Bourbon of the Black Organization, and is shown to be one of the few operatives Vermouth is willing to work with.]]

* {{Bishonen}}
* DarkSkinnedBlond
* {{Homage}}: to [[MobileSuitGundam Amuro]]. complete with white RX-7 which is ShoutOut to '''RX-7'''8-2. And with the same seiyuu, to boot.
** [[spoiler: His real name comes from both the character and seiyuu as well.]]
* [[spoiler: TheReveal: When he announces his Bourbon codename in front of a normally sized Shiho Miyano (Kaito Kid in disguise) during the Mystery Train arc.]]
** [[spoiler: Much later, it ''also'' turns out that he's actually a mole infiltrating the Black Organization. Although all that's known about his actual allegiance is that it's not the FBI, which he has some disdain for.]]
* InterGenerationalFriendship: He's implied to have had one with [[spoiler: none other than Elena "Hell's Angel" Miyano.]]
* SherlockScan: [[http://www.mangareader.net/detective-conan/796/3 Here]]
* ShoutOut: His name, [[MobileSuitGundam Amuro]].
* [[spoiler: MasterOfDisguise: As Scar Akai. Apparently he had some help from Vermouth for that.]]
* [[spoiler: TheMole: He is Bourbon. And the fake Akai that was around for a while.]]
* MysteriousPast: Previously attended the police academy and was a friend of Takagi's deceased superior, Wataru Date. [[spoiler:Becomes even more mysterious after one wonders how someone from the police academy became a member of the Black Organization, or if he was already a member of the Organization before applying to the academy.]]
* [[spoiler: WellIntentionedExtremist: In order to further infiltrate the Organization's inner circle, he planned to run over an elementary school teacher and hand over Shuuichi Akai to them. Akai calls him out on this, reminding him not to forget their true targets.]]
* [[spoiler: WhamLine]] : During the Mystery Train arc. [[spoiler: "Bourbon... that's my codename!"]]
