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

Conan and the Detective Boys' class teacherm 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 met again, adulthood and time had changed them throughly (Shiratori was quite more prideful, Kobayashi 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"]] [[LoveAtFirstSight upon laying his sight on her]], 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.
* FlowerMotifs: Sakuras. Which turn out to be [[spoiler:a huge hint that she was Shiratori's true love from childhood.]]
-->'''Young Kobayashi:''' [[spoiler:Because the sakura is the symbol of police officers! Determined, kind, and dignified. It's a flower of justice!]]
* 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 she 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}}: A rare adult version.
* MoralityPet: Downplayed. While [[spoiler:Shiratori]] is far from evil or a being a straight up jerk, it's all but stated that [[MoeCouplet she brings out the best in him.]]
* NiceGirl: 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 and her students love her to boot. [[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 and protective behavior, but what made her ''actually'' fall in love with the guy 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, poor 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.

!!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: Just look at him!
* KindHeartedcatLover
* {{Megane}}: The glasses he wears highlight his physical beauty.
* 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.]]
* 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.

Ran and Sonoko's English teacher.

* FunnyForeigner: [[InvokedTrope Invoked]] by Jodie during her initial appearances to [[ObfuscatingStupidity make people put their guards down when facing her.]]
* NoCelebritiesWereHarmed: JodieFoster
* RedHerring: [[spoiler:Was a very obvious suspect for being Vermouth for a long time. A blonde American woman with suspicious skills investigating at Conan's school, she even used Vermouth's famous CatchPhrase, "A secret makes a woman woman". Turns out she's an FBI agent looking for Vermouth who has picked the phrase up from her enemy.]]
* SecretKeeper: Quoting [[spoiler:Vermouth]]: "Secret makes a woman woman."
* WitnessProtection: [[spoiler:She was in one after seeing her parents killed by Sharon.]]

* SelfMadeOrphan: [[spoiler:Very tragic case, since it was less about hate and more about having to...]]
* ShootYourMate: [[spoiler: She shot her ''father'' to hide the fact that they were CIA [[TheMole moles]] infiltrating the Dark Organization.]]
** And again, she has to do this to [[spoiler: Akai. Per orders of ''That Man'' himself. Somehow, however, he survives.]]

* SugarAndIcePersonality: [[spoiler: She acts cold and efficient when with the Organization, but her kind nature often shines through. Hence why Gin and ''That Man'' don't always trust her.]]

[[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.]]

* KansaiRegionalAccent: He was born and raised in Osaka

* 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!

* 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]]...

* {{Bifauxnen}}: he'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.
