    Conan Edogawa/Shinichi Kudo 

    Ran Mouri 
https://static.tvtropes.org/pmwiki/pub/images/ci_19387_1364477468.png
Voiced By Wakana Yamazaki (JP)/ Colleen Clinkenbeard (EN), Erika Araujo-Robledo and Angelines Santana (first Latin American Spanish dub), Mayra Arellano (movies 1, 2 and 18 onwards plus first Lupinthe Third crossover and Magic Kaito 1412, Latin American Spanish dub) Jessica Toledo (third Latin American Spanish dub), Berta Cortés (first European Spanish dub), Diana de Guzmán (second European Spanish dub, first part), Carolina Tak (second European Spanish dub, second part and movies), Nuria Trifol (third European Spanish dub), Tomoka Kurokawa (2006 Live-Action Drama Actress), Shiori Kutsuna (2011 Live-Action Drama Actress)

Shinichi's childhood friend and love-interest. When Shinichi shrinks and takes on the name Edogawa Conan, she takes on the big sister role and looks out for Conan like if he was any other little kid. Ran also wishes for her parents to get back together and tries but fails time and time again at forcing a set-up between the two.

She also happens to be well-trained in karate at the expense of anyone trying to take advantage of her.

Mandatory name note: The entire name came from Maurice Leblanc, creator of Arsène Lupin, through the Japanese reading Mooritsu Ruburan.

Dub Name Change: Rachel Moore.


  • The Ace: Ran is a karate champion, an excellent cook, gets good grades, popular with the opposite sex, and is a well liked person.
  • Action Girlfriend: Subverted. She is Shinichi's Love Interest but he's stuck as Conan and therefore, whenever she goes Mama Bear on anyone that threatens him, she doesn't know she's actually defending her "not"-boyfriend.
  • Affectionate Nickname: "Angel" by Vermouth due to saving the latter's life in New York.
  • Age Lift: Downplayed. The difference isn't too extreme but still noticeable. In the manga, Ran is 16; in the anime, Ran's age is increased by a year.
  • All-Loving Heroine: Ran is a genuinely Nice Girl, who has enough compassion for murderers (well, some), and will never hesitate to save someone's life. Criminal or not.
  • Almost Kiss: In canon, when she and Shinich almost kiss during the theatre play; she does score a kiss in the non-Canonical Movies. In the current chapters, she does give him a kiss on the cheek.
  • Anguished Declaration of Love: Ran gives one to Shinichi in the eigth non-canon movie, "The Magician of the Silver Sky", as she chews him out on how confident he is about how he will protect and guide her through landing the plane but is never physically there for her except as a phone call. And after a few rough moments from the plane, she confesses her love to him. However, while Shinichi (as Conan) does hear her confession, she thinks that she was talking to Kaito Kid, and refuses to reveal what she said to the former when he asks.
    Ran: What is this? You're acting all confident...Do you even know? That the lives of all the passengers are in my hands?! Don't act so confident about it! When I really need you, you're never here...All I get is a phone call! Even when you finally make it back, you're gone again in the next instant...Every time...Every single time. You're always leave me behind, all alone... What do you take me for?! I...I love you...Shinichi.
  • Animal Motifs: Haibara states Ran would be similar to a dolphin. A description that matches Ran perfectly due to her approachable nature, cuteness, and loyalty.
  • Anime Hair: If it's not for her "horn", her hair would look perfectly normal. It keeps magically changing sides depending on which direction she's facing to.
  • Badass Adorable: Adorable all the time and can always kick ass.
  • Badass in Distress: More in The Movies. In Captured in Her Eyes, after spending almost the while movie as a quiet Ophelia afflicted Trauma-Induced Amnesia, as soon as she recovered her memories she beat the shit out of the Big Bad, who caused it by shooting Sato almost to death in front of her.
  • Barbie Doll Anatomy: Ran in some of the OP and ED animations-shown nude either in full body (without anything showing), or implied by showing a close-up with bare shoulders. Presumably intended to imply Ran's vulnerability from being kept apart from Shinichi for so long.
  • Because You Were Nice to Me: Her friendship with Shinichi began after he defended her from bullies when they were children.
  • Belligerent Sexual Tension: With Shinichi. They tend to argue from time-to-time, but they have romantic feelings for one another.
  • Berserk Button: Ran gets quite peeved when she thinks that Shinichi may be committing infidelity (even though they're not in a relationship prior to 1005).
  • Beware the Nice Ones: Ran is one of the kindest, bravest, and selfless characters in the WHOLE franchise. You don't want to make her use her karate skills on you.
  • The Big Damn Kiss: At the end of chapter 1004, Ran gives Shinichi a kiss on his cheek as an answer to his love confession. In public.
  • Big Sister Instinct: Don't try to kill Conan with her in the vicinity.
  • Birds of a Feather:
  • Boobs of Steel: She's quite the fighter, and possesses rather large breasts. Which once in a while are the subject of visual gags.
  • Born Lucky: Ran has absurdly good fortunes playing luck-based games like Poker or Mahjong. First seen when she goes into a mahjong parlor where her father Kogoro is gambling, very upset because he took Conan with him... then she gets interested in the game itself... and in the next scene she has fleeced her dad and his companions out of all their "prizes". (And then the owner of said parlor, who doubled as a loan shark, appears dead...) Another case started with her aiming to win the second prize in a raffle, which was a family trip to the beach. Conan was all "I don't think you'll win"... Cue to the next panel, with Ran happily telling Kogoro about the trip she won and a terrified-looking Conan next to her.
  • Broken Pedestal: With assistance from Shinichi/Conan, Ran exposes the murder culprit in the "Ski Lodge Murder" case is her former elementary school teacher, Akiko Yonehara; this also meant that her teacher was also the one who attempted to strangle Sonoko. At the end of the deduction, she cries while hugging Conan in despair.
  • Cannot Spit It Out: Even though Ran is in love with Shinichi, she has repeatedly failed to convey her feelings because she suddenly becomes self-conscious.
  • Character Development: In earlier stories, she would become violently suspicious if she thought Shinichi was philandering, although more recently his confessions (in the "Holmes' Revelation" Arc) have led her to trust his intentions.
  • Characterization Marches On: Early-manga Ran is noticeably more Hot-Blooded and petty than her later All-Loving Hero characterization; in the "Art Museum Murder Case", Conan/Shinichi implies she regularly busts out karate moves on furniture when she doesn't get her way.
  • Charles Atlas Superpower: Through nothing but the karate practice she leads at school while otherwise leading a normal girl's life, Ran Mouri can take out a small army of hired thugs and knock out armed criminals. She can apparently even do the bullet thing, at least in one of the movies. Don't think about it too hard. It could also be a slight case of It Runs in the Family. At least home schooling has been mentioned, and both Kogoro and Eri know their Judo pretty well.
  • Chef of Iron: Frequently noted to be an amazing cook and is a karate champion.
  • Chickification: Invoked in the Tori Man Mugging case. She begins to stop fighting criminals she encountered because of a love fortune that advised her to avoid "unfeminine" activities. Deconstructed in the same case because her new-found meekness caused far more problems for the case than it could have been otherwise. Subverted in the very end when the criminal read her true fortune that was swapped out by Sonoko to advise Ran to just Be Yourself because the guy will detect if she is being someone else and her feeling will be answer. She then proceed to soundly kick the criminal's ass.
  • Childhood Friend Romance: With Shinichi. They've known each other since pre-school and are each other's canonical love interest.
  • Childhood Friends: Ran has known both Shinichi and Sonoko since they were four. Her relationship with the former grew beyond friendship.
  • Children Raise You: For Kogoro, her Manchild father. She acts more like his mother or wife than his daughter.
  • Chronic Hero Syndrome: Ties in nicely with her Nice Girl personality and All Loving Heroine philosophy.
  • Clingy Jealous Girl: Ran is a very sweet and kind Nice Girl who borders on All-Loving Heroine... unless she's given a reason to be jealous of a girl getting close to Shinichi. Then she gets very jealous. Thankfully, her niceness tends to shine back through.
  • Clueless Dude Magnet: Ran is typically unaware of her own attractiveness, and usually remains oblivious when men try to flirt with her, often to Sonoko's exasperation, who believes her wait for Shinichi to be hopeless.
  • Cool Big Sis: Acts like a kind, fun, and protective older sister figure to Conan, Ai, and the Detective Boys.
  • Covert Pervert: The sisterly (sometimes motherly) and friendly Ran often has some...interesting thoughts whenever she thinks Shinichi may be involved with another woman. This is more evident in the manga, where at one point, she imagined Shinichi with another woman...in what seems to be after they had sex.
  • Cultured Badass: Ran appreciates the fine arts and has been noted to have a great singing voice. She can also play the piano.
  • Cute Bruiser: Plays karate on the national level. Dere-dominant Tsundere. For proof: there's an episode where Ran (Assisted by Makoto, Sonoko's Genius Bruiser boyfriend) took out 50-60 gang members, many armed with katanas. It took 12 minutes, and not a hair was out of place.
  • Daddy's Girl: Kogoro may exasperate Ran with his constant drinking, womanizing, and over all laziness, but if you call him a lousy detective or take away his business, she'll do this. On the other hand, Kogoro is pretty much an Overprotective Dad and one of the best ways to make him act competent is to look at his little girl in anything similar to a wrong way.
  • Damsel out of Distress: Her waifish figure and cute face make Ran a frequent target of criminals seeking some kind of human shield. Scenes like this one prove why this is a terrible idea.
  • Demoted to Extra: In the 20th movie, Ran only has a handful of screen-time moments. A sharp contrast to how much she appeared in the previous movies.
  • Deuteragonist: To Shinichi/Conan's protagonist.
  • Dude Magnet: Like her "detective boyfriend", Ran has received a very high amount of attraction from the opposite sex men and so far one girl being attracted to her.
    • In many of the cases she's involved in, at least one man has tried to flirt with her.
    • There's Shinichi, who she only has eyes for. In fact, Shinichi has loved her from the moment they met in pre-school.
    • During the "Sonoko's Dangerous Summer Story" case, Sonoko comments on how most of the men that came to them and Conan only came because they wanted to flirt with Ran.
    • Eisuke Hondou fell for Ran the first moment he met her and wanted to take her to America with him.
    • Okita, Heiji's kendo rival, hits on her the first time they meet. The guy has actually a serious crush on another girl, though.
    • Kaitou Kid at one point tried to kiss (and grope) her in a non-canonical movie.
    • In a non-canon OVA, Dr. Araide apparently asked for her hand in marriage, but it turned out to be Conan's dream.
  • Establishing Character Moment: Within a page or two of her introduction in the very first chapter, we see her crack a concrete pole with a single punch. Ran Mouri is ridiculously strong. Ok, duly noted.
  • Even the Girls Want Her: If we take Sera's "she's just my type" and Sonoko's Ambiguously Bi moments seriously.
  • First Love: To Shinichi, he has been in love with since they were both four.
  • Flower Motifs:
    • In "The Nocturne of Red Murderous Intent Part 2", Conan brings Ran a bouquet of blossoms, specifically peach blossoms; peach blossoms represent happiness of love. It's also related with longevity, when reading the kanji for “hundred” 百 (momo) the same way as the one for "Peach tree" 桃 (momo). It could also mean everlasting love, and since it's a spring flower, it's also associated with weddings.
    • Ran's name is spelled with the character for orchid (蘭), a fact several of the endings have referenced.
  • Friend to All Children: She's a nice person in general, but especially the Detective Boys all like her very much. Ai is a little more skittish at first, being somewhat jealous of and intimidated by her popularity; she later warms up to her too when at some point she reminded her of the recently murdered Akemi. There really doesn't seem to be a child in the world that she could not get along with.
  • Genius Bruiser: Downplayed. There's more emphasis placed on her amazing karate skills than her smarts. However, in the moments where she does solve a case, Ran displays a very good memory for history, and has used her knowledge to contribute to an investigation cases more than once.
  • Girly Bruiser: Karate champ, strong willed and, wears many types of dresses.
  • Girly Girl with a Tomboy Streak: Ran often wears girly dresses or skirts, is a Supreme Chef, likes cute things, loves the fine arts, is a sucker for romance, and is an emotionally sensitive person. She's also a world-renowned karate expert and can be Hot-Blooded in certain situations.
  • Good Is Not Soft: Yeah, Ran's one of the kindest and compassionate people that you'll know in anime and she won't hesitate to help anyone, friend or foe. That doesn't mean she can't dish out a deserved physical punishment.
  • Hairstyle Inertia: Ran's "horn" has been a part of her hairstyle since childhood.
  • Heartbroken Badass: Whenever she discusses how Shinichi's absence troubles her. Doesn't help that she cries when she does.
  • Hello, Nurse!: Men often pick her up instead of Sonoko. To the chagrin of the latter.
  • Heterosexual Life-Partners:
    • Has been friends with Sonoko since childhood and have always been loyal best friends who can confide in one another about their problems.
    • Ran later develops one with Kazuha — They have become close friends since their second time they met and seem to regard each other as confidantes, since they are in similar romantic situations; and when Shinichi/Conan and Heiji are on cases together, Ran and Kazuha almost always spend the time together.
  • Hidden Depths: Ran has a very good memory and attention to detail, having used her both to contribute to a case investigation more than once. This led her to be the only character that isn't specifically stated to be a genius or is tied with the Black Organization to be suspicious of Conan's real identity. The only reason she didn't figure out is because he spent extra effort to hide and deceive her and because she is too trusting of both Shinichi and Conan.
  • Hot-Blooded: Thanks to her Tsundere tendencies or when her loved ones are threaten.
  • Hyper-Awareness: Ran has shown very alert senses in darkness, able to notice an attacker with a weapon and strike to protect herself.
  • Identical Stranger:
    • Ran is said to look a lot like a younger version of Ai's dead older sister Akemi, to the point that Ai was reluctant to get close to Ran because she was still reeling from her terrible loss... but once Ran saved Ai's life, she became almost desperately protective of Ran as a result. It even gets lampshaded when Ai once stares at Ran and pretty much sees her as Akemi.
    • During the "The Twenty Year Old Murderous Intent: The Symphony Serial Murder Case" case, two people notice Ran baring a striking physical and character resemblance to the deceased Yoshimi Samezaki; those two people are the deceased's father (Toji Samezaki) and fiance when she was alive (Minoru Ebina).
    • In the DC vs. Lupin III special, with Crown Princess Mira, a troubled young girl who's caught in a conspiracy after the death of her mother, Queen Sakura, and her heir Prince Gill.
    • Despite she mistakes Kaitou Kuroba for Shinichi, nobody seems to notice the similarity between her and Aoko Nakamori.
  • I Know Karate: Either she or someone else will mention that she is a karate champion.
  • I Know You Know I Know: Know Shinchi very well, as the last time Kaito disguised himself as him she knew he is fake. He tried to grab her butt.
  • Improbable Hairstyle: Ran's trademark feature is a large lock of hair many fans refer to as her "horn".
  • Informed Ability: Apparently Ran is a good singer, but she has yet to actually sing.
  • It Was with You All Along: Ran is constantly looking for her childhood friend Shinichi, who is with her all along as a little boy named Conan Edogawa. Conan himself lampshades this at one point. Ran still doesn't realize this fact up to the present manga chapter.
  • I Will Wait for You: To avoid making Shinichi choose between her and his important case (really an excuse because Shinichi has turned into Conan and can't return), she has decided to wait for him to finish it, trusting his promise that he will come back despite their separation causing Ran a lot of emotional pain.
  • Kiai: She always does that before or when she attacks. It is shown a couple of time that she needs to focus her energy first before performing a move that requires a lot of power. Her kiais are rather low-pitched.
  • Kick Chick: Most of her karate techniques she uses are kicks.
  • Lady and Knight: The Lady to Shinichi's Knight. While Ran is fairly strong, there's an arc involving her as a princess in a School Play that exploits the "princess and knight" symbolism to the hilt with her and her mutual childhood love interest Shinichi, who is mostly stuck in a child's body (as the titular Conan) but is temporarily back to his real physical age during said arc. Additionally, during Lupin III vs. Detective Conan, Ran daydreams of herself as a princess and Shinichi as her knight.
  • Lightning Bruiser: Despite her slender frame, Ran has considerable raw strength for her frame, as seen from prying open powerless elevator door. She is also shown to be remarkably fast, able to quickly react to and knock away falling pipes and likewise dodge a bullet up-close while on guard. Her strikes have also shown similar speed, able to swat down a bee with a single kick.
  • Living Emotional Crutch:
    • Ran is this to Shinichi. The thought of her showing interest in other guys makes him almost childishly jealous and it's mostly Played for Laughs. At worst, whenever Ran has disappeared/been attacked/been wounded/ believed to be dead, Conan has either fallen into Heroic BSODs and, at least once, has been dangerously close to crossing the Despair Event Horizon. The best evidence comes from the sixth non-canon movie, Conan basically gave up all hope of getting out of the virtual game, when Ran sacrificed her life to save him from Jack the Ripper. And in both canon and non-canon material, Shinichi has often referred to Ran as his "most precious person in the world".
    • Ran grows to become this to Haibara. At first, Haibara avoided her because it was her usual attitude and Ran's strong resemblance to her dead sister. However, after spending some time together and Ran saving Haibara from being killed by Vermouth, Haibara now takes a special interest in protecting her from the Black Organization.
  • The Load: If her martial skills are not requested, generally she doesn't contribute much to the resolution of the cases. However, she often drops Conan/Shinichi some hints that help him to solve cases, even when she is unaware of the nature of those hints.
  • Locked Out of the Loop: Out of everyone, Shinichi is most adamant about keeping his identity as "Conan Edogawa" and the Black Organization a secret from Ran as much as possible.
  • Long-Distance Relationship: A variant with Shinichi. She thinks that he has run off to investigate some kind of case, but in truth he's Conan, aged down thanks to plot.
  • Lovable Jock: One of the best on her karate team and is one of the sweetest characters in the series.
  • Love Epiphany: The "Shinichi Kudo's New York" case reveals that Ran first realized her love Shinichi was after they both saved a serial killer at the time (who was Vermouth) in disguised. When the disguised killed asked why they would do something like that, Shinichi responds that while he can't understand why people kill, there doesn't have to be a reason to save a life. Thanks to Shinichi's answer Ran realizes that the earlier murder wasn't her fault... and when she finally wakes up out of the dreams, she remembers how that night was the night she realized her feelings for Shinichi and how important he is to her.
  • Love Interest: She is Shinichi's Love Interest and she's the only person he has romantic feelings to.
  • Loves My Alter Ego: Inverted. She loves Shinichi (the original person), but she also deeply cares for Conan (new identity).
  • Meaningful Name: Also doubling as Punny Name. Ran likes to rush wherever she goes, believing her name to be like the "Run" word from English. She even said to Shinichi that, "My name is Ran! I was born to run!"
  • Mindlink Mates: With Shinichi — they appear to share a close empathic link due to their strong feelings for each other, making them almost impossibly aware of when the other is in extreme danger, and often able to sense the other's worried thoughts.
  • Morality Pet:
    • Along with Shinichi, she is this to Vermouth from the Black Organization. After Ran saved Vermouth's life in New York City, Vermouth nicknames Ran "Angel". Earlier, Vermouth, as her Sharon Vineyard role, complained that her life was a series of misfortunes and, "No angel has smiled upon me, not even once." Even though Vermouth in disguise prepared to kill Ran later, Ran stopped Vermouth from taking a fatal fall. Vermouth was touched by this act of kindness. Much later in the story when Ran shielded Haibara from gunfire with her body, Vermouth refused to shoot Ran or allow her to be shot, instead firing around her in an attempt to frighten Ran into releasing Haibara. Vermouth has stated that Ran and Shinichi are the only two treasures she has in the world.
    • Downplayed in regards to Shinichi. He isn't a a psychopath or even a straight up jerk, but one reason for his lack of close friends was because his arrogant personality was a negative turn-off to many of his classmates and even teachers, making it hard to befriend him. Ran was the only exception.
    • Eventually becomes one to Haibara after she saved the latter from being killed Vermouth. Since then, Haibara has taken a special interest in protecting Ran from Black Organization.
  • Muscles Are Meaningless: She has a curvy, normal build for a teenage girl. She can also hurl men who are twice her height and/or triple her weight and punch small craters in brick walls with a cheerful smile on her face.
  • Nerves of Steel: She has remained bold, steady, confident and calm in many situations that would usually cause others to remain frozen in fear, such as being threatened by a gun or surrounded by flames.
  • Nice Girl: Ran's greatest personality trait is that she genuinely cares for those she loves. She is also patient, kind, and nurturing.
  • No Sense of Direction: She easily gets herself lost.
  • Official Couple: She accepts Shinichi's as her boyfriend at the end of chapter 1004 and doesn't hide her feelings for him anymore.
  • One-Woman Army: During one case, Ran was able to successfully take out 50-60 gang members...who had katanas.
  • Only Friend: Before turning into Conan, Shinichi's primary friend was Ran.
  • Out of Focus: Her role in plots regarding the Organization was diminished increasingly as time when on and introducing many more characters. Compare and contrast her involvement in arcs that involve Vermouth and the later Organization arcs.
  • Passionate Sports Girl: The source of her Action Girlness. And she takes her karate very seriously.
  • Plucky Girl: Tearful and sensitive as she can be, it's not easy to make her give up.
  • Protectorate: Shinichi/Conan will always make sure that no harm comes to Ran.
  • Punny Name:
    • Ran is nicknamed "Ranmaru" by her rival and good friend, Hina Wada based on "Mori Ranmaru"—a famous samurai affiliated with Oda Nobunaga.
    • Ran says she's born to run because of her name.note 
  • Rapunzel Hair: Her hair reaches down her waist line.
  • Red Oni, Blue Oni: The calmer, sensitive Blue Oni to Kazuha's Hot-Blooded, temperamental Red Oni.
  • Relationship Upgrade: As of file 1006, she and Shinichi are officially a couple.
  • Replacement Goldfish: To Ai, since Ran greatly resembles her dead sister.
  • Rescue Romance: With Shinichi — they've mutually helped and rescued each other (even if Shinichi is in his Conan form almost all the time) several times - often a great risk to themselves. Lampshaded once when Ran's drugged and almost forcibly drowned at some point, then Conan rushes in to help her; thanks to the drug and lack of oxygen she sees Conan as Shinichi, and before passing out she smiles and says "Don't worry, I'm okay... Shinichi came to save me..."
  • Savvy Guy, Energetic Girl: With Shinichi, especially when they were younger and when they aren't bickering, she's the emotional, chipper Energetic Girl to Shinichi's aloof, stoic Savvy Guy.
  • Secret Secret-Keeper: An incident involving blood transfusions implies she might know that Conan is Shinichi. The whole Desperate Revival plan has to be created to make her believe otherwise.
  • Shipper on Deck:
    • Ran wishes for her parents to get back together.
    • She supports Heiji and Kazuha becoming a couple.
    • She ships Sonoko and Makoto.
    • Ran seems to think that Conan and Ai would be cute together.
  • Single-Target Sexuality: Even though it took her slightly longer than Shinichi, Ran has only ever had eyes for him.
  • Single Woman Seeks Good Man: Some people have wondered why Ran would like a guy like Shinichi... Well, in a private discussion with Conan (aka Shinichi himself), Ran stated that while he may have an unpleasant personality, he's also brave and someone you can rely on in a pinch. In fact, Ran first realized she was in love with him when he helped save a Serial Killer from falling to his death. When asked by the said killer why he [Shinichi] would even consider doing such an act, Shinichi responded with: "People kill each other and I don't understand, but for saving a life, is a logical reason necessary?"
    Ran: (to Conan) Ever since he [Shinichi] was little he was a jerk, always full of himself, and a mystery otaku. But whenever you need him, he's dependable and brave and cool. I really like Shinichi!
  • Star-Crossed Lovers: With Shinichi. While their feelings have been kinda wavering for quite the while, as time passes they have grown stronger - but Shinichi is trapped in the body of a little boy (the titular Conan) and cannot openly tell Ran who he is, lest she and his friends will be targeted by the same evil organization that shrunk him. In the meantime poor Ran waits for Shinichi's return...
  • Strong Family Resemblance: Ran gets her physical looks from her mother, with the only thing she got from her father was her dark-brown hair.
  • Strong Girl, Smart Guy: With Shinichi. While Ran is karate champion whose strength borders on Charles Atlas Superpower, he's a Teen Genius detective who can solve supposed impossible crimes.
  • Supreme Chef: Ran is a Karate expert and has been repeatedly told she's a great cook.
  • Tender Tears: Lampshaded by Shuuichi Akai.
    Akai: You are crying again... You are always crying.
  • Thou Shalt Not Kill: Best summed with this quote:
    "Courage is a word of justice. It means the quality of mind that enables one to face apprehension with confidence and resolution. It is not right to use it as an excuse to kill someone."
  • Tomboy and Girly Girl: One may think she's the tomboy to Sonoko's girly girl, but Ran is more complex than that. Sonoko is less physically active and more boy-crazy/fashionista than Ran, but is also more outspoken and straightforward than her (unless Ran's in tsuntsun more, yeah). In fact, their friendship started when Sonoko protected Ran when they were children!
  • Tsundere: She's default Type B or deredere (gentler). Just don't piss her off.
  • Twice Shy: With Shinichi. Even after he became aware of her feelings for him as Conan, when he returns to his original body, he gets too scared to properly confess...until the London arc. And after the said arc, it takes her about 250 chapters to give him an answer.
  • Undying Loyalty: She'll never turn her back on her loved ones. Especially Shinichi, who she has the utmost faith in, believing he can save her or anyone from needless violence.
  • Violently Protective Girlfriend: Subverted. She and Shinichi are each other's love interest, but aren't technically together, since Shinichi has turned into Conan. Everytime Ran gets protective of him, it's more like Big Sister Instinct and/or Mama Bear.
  • Wacky Parent, Serious Child: The Cute Bruiser Serious Child to Kogoro's Manchild Wacky Parent.
  • The Watson: Shinichi has a tendency to call her "Watson" and she tends to play this role in flashbacks.
  • Weaksauce Weakness: Ran gets easily sick when reading in a car.
  • What Does She See in Him?: Others, especially Sonoko, can't understand why Ran would like mystery otaku like Shinichi. Ran answers this question when talking to "Conan" that despite his flaws, Shinichi has many other admirable qualities she loves, such as his bravery and reliability. Also, in a private conversation with Kazuha, Ran admits that despite calling Shinichi a "mystery geek" to his face, she actually thinks he looks cool when he solves a case.
  • What Would X Do?: Whenever Ran is faced with a particularly difficult situation she would often question what would Shinichi do if he was in the same predicament.
  • Why Did It Have to Be Snakes?: She has a fear of ghosts. Not because they're supernatural per se, though, but because they're intangible—meaning her martial arts will have absolutely no effect. A culprit assumes that she's afraid of anything remotely scarely, only for Ran to reply that she's afraid of ghosts, not of idiots and then beats the shit out of him.
  • Wise Beyond Her Years: Ran is very self-sufficient for her age, since her father is often drunk, slovenly, and fiscally irresponsible. She handles many of the Mouri household's financial affairs and all the cooking and housework.
  • You Remind Me of X: Both Shuichi and Haibara have noted how Ran is very similar to Akemi in both appearance and personality.
  • Zettai Ryouiki: Sports the look from time to time. It's quite noticeable in the first OP, where she sports a Type A... if she added Twin Tails, her Type B Tsundere traits would give her a Grade S.

Voiced by Akira Kamiya / Rikiya Koyama (JP)/ R. Bruce Elliot (EN); Juan Zadala, Carlos Carrillo and Roberto Alexander (first Latin American Spanish dub); Víctor Covarrubias (movies 1 and 2 and 18 onwards plus first Lupinthe Third crossover, Latin American Spanish dub) Sergio Schmied (third Latin American Spanish dub), Luis Espinosa (first European Spanish dub and second part of the second one), Ángel Amorós (second European Spanish dub, second part and movies), Takanori Jinnai (Live-Action Drama Actor)

Ran's father and estranged husband to Eri Kisaki.

He runs a private detective agency, but is mostly out of the job due to his constant drinking, gambling, womanizing and being described as a joke regarding the cases he actually takes. That all changes after Shinichi shrinks and needs a scrapegoat to solve the cases for him; bringing to life the Sleeping Kogoro, which Kogoro later becomes famous for and allows him to take more noteworthy cases. Though, he's still heavy on the drinking, gambling and womanizing.

He also happens to be a big fan of the idol singer, Yoko Okino.

Mandatory naming note: "Kogoro" came from Kogoro Akechi, the Great Detective in Rampo Edogawa's novels.

Dub Name Change: Richard Moore.


  • Action Dad: A master in judo and the father of the deuteragonist, Ran.
  • Adults Are Useless: Well, considering that Shinichi/Conan and other teen detectives are in general more competent and active than everyone. To be fair, he often comes to conclusions a real life detective would think, given the extremely elaborate nature of these cases. His Fatal Flaw is the fact that he's impatient and rather shortsighted - he wants to finish every case as fast as possible. When it comes to apprehending known criminals, he's shown to be far more competent.
  • Adult Fear: A couple of times, when Ran is in danger, who is always eager to rescue her out of fear. The earliest time he had his fear was when a group of three adults tried to kidnap 4-year-old Ran in kindergarden, and Kogoro had a very furious look on his face when he was about to arrest one of them (and that was just Kogoro's first week as an officer of the headquarters).
  • Aesop Amnesia: Despite seeing how Conan's hints help in solving cases and how Heiji is actually a competent detective, Kogoro still thinks both of them are nuisances to an investigation.
  • Alcoholic Parent: Frequently gets intoxicated and it's played for both drama and comedy. In the "Drama" part he does have a good perception in solving cases at times, but most of the time, he just wastes time drinking (to the point Ran is the one who keeps the house in order and, in at least one case, he's seen straight-up drinking his sorrows away because he can't handle that a kind girl he used to know is the most likely culprit. In the "comedy" part, he's seen dancing or sleeping drunkenly with his tie around his forehead and is more of a Butt-Monkey than usual.
  • Amazingly Embarrassing Parents: To Ran, and to Conan in a Parental Substitute way. He's a clumsy, womanizing father who's main vices include alcohol and gambling. She once chewed him out for taking Conan to a mahjong parlor behind her back.
  • Aww, Look! They Really Do Love Each Other: Has many such moments with his estranged wife, Eri. Pretty much whenever they meet, they spend the entire time nagging each other, but these episodes usually end with a clear indicator that they still care for each other.
  • Badass in a Nice Suit: Officially starts to sport this look after his fame as a detective skyrocketed.
  • Badass Moustache: His mustache is well-trimmed.
  • Badass Teacher: He was able to teach Judo to Ran and Eri.
  • Belligerent Sexual Tension: With Eri. They are a married couple and argue to hide the fact that they want to live with one another again.
  • Beneath the Mask: It's shown only a few times, but it shows. While on the surface he looks like a womanizing, drinking jerk, he's actually a Sad Clown who feels like he's a horrible father to Ran and he deeply regrets being away from Eri for so long.
  • Berserk Button: Anyone double-crossing, tricking, lying, or downright betraying him; finding out that one of his True Companions from college was not only a murderer, but that they had killed another member of his group of friends had Kogoro completely fuming like few times it has happened in the whole manga.
  • Beware the Silly Ones: Yeah, he's a shameless flirt, embarrassing father, and too many other flaws to count. He's also a master of judo and doesn't take either betrayals/lies and/or threats against his loved ones well.
  • Big Ego, Hidden Depths: Beneath Kogoro's enormous and inflated ego is a man who doubts himself as a father and is lonely from the absence of his wife.
  • Brilliant, but Lazy: To a certain degree. He's actually quite capable as a detective, but he usually just wants the case to be over and done with, so he assumes his first theory is right and refuses to believe otherwise until proven wrong. His main problem is that he usually does not bother to closely examine all the evidence, so he never finds those crucial details pointing to the culprit. Even when Conan hands him these details, he's too lazy to think things through completely or examine every possible solution before making an accusation.
  • Bumbling Dad: To Ran and Conan. Basically a loser, but his care towards his daughter Ran is utterly remarkable.
  • Butt-Monkey: If something funny, humiliating or painful is going to happen, the first-rate candidate is Kogoro.
  • Cannot Spit It Out: Even though he desperately misses having Eri home, he'll never admit it. The one time he did ask her to come back home, she pretended she was listening to a tape, citing her reasons "he wasn't ready yet".
  • Can't Act Perverted Toward a Love Interest: Kogoro will flirt with every cute girl and beauty except Eri, or anyone who looks like her, much to Sonoko's wonder. He also sometimes becomes cooler and more perceptive when he meets someone that reminds him of her.
  • Can't Live With Them, Can't Live Without Them: With his estranged wife, Eri. At one point, Kogoro even outright states that he cannot bear being separated from Eri and asks her to come back, but she pretends she didn't hear him because she's not ready yet.
  • Casanova Wannabe: Has a habit of hitting on pretty women with no luck. However, this only goes as far as flirting and it's heavily implied he does this as a self-defense mechanism to protect him and Eri from anymore emotional pain.
  • Character Tics: Subverted. When he goes into "Sleeping Kogoro" mode he makes a weird noise and looks down to the ground before beginning his deduction. In reality, it has less to do with being an inborn habit but Conan using a tranquilizer on him.
  • Chick Magnet: His rise as a famous detective has many women fawning over him.
  • Childhood Friend Romance: With Eri. They have known each other since elementary school and are now married, if estranged.
  • Clueless Detective: He's a tad too tunnel-visioned, so he usually jumps to the most obvious deduction, frequently the one the culprit wanted the investigators to believe. Because he's got a severe case of tunnel vision, he never bothers to look for further evidence or question his conclusions after that, which is why he almost never finds the correct solution.
  • Crazy Jealous Guy: An old high school friend even stated that Kogoro would glare at any guy who looked at Eri.
  • Crouching Moron, Hidden Badass: Something (usually a personal matter) might cause Kogoro to actually focus all his attention on a case, revealing him to actually be a very capable detective on his own. This is most evident when it comes to apprehending known criminals, or if someone presses his Berserk Button...
  • The Cynic: In cases, he usually goes with the most straightforward way the criminal committed the crime, hardly accepting any other theories.
  • Defective Detective: He's horribly bad with money, is often seen drinking or gambling and can't fix his relationships with his estranged wife. Before Conan helped him gain some success as a detective, he was completely down on his luck, but even now he clearly has issues. Alternately Played for Laughs or Drama.
  • Delinquent Hair: Since his childhood, Kogoro's hair has been styled as a little pompadour. Nowadays, his moustache takes focus from his hair away, which makes his hairstyle less noticeable.
  • Drink Order: Beer is his favorite alcoholic beverage, and while he's not a commoner he is of middle-class.
  • Dumb Muscle: Downplayed. The one thing Kogoro can do right is his judo. But even though he can be quite the incompetent detective, it's more out of impatience than actual stupidity since he does so flashes of being on the same deduction level as Shinichi when there's a personal case to him in which he applies himself.
  • Everyone Has Standards:
    • In the non-canon movie, The Time-Bombed Skyscraper, Kogoro is pissed that Shinichi left Conan alone with a phone (connected to the criminal), when the said kid could've been in grave danger.
    • He also thought Commissioner Hattori hitting his son in a case was going too far and really objected to how he manipulated said son into getting the criminals to reveal themselves.
  • Expository Hairstyle Change: In middle school, Kogoro's hair was spikier and unkempt. However, upon high school and the current storyline, his hair is now combed down.
  • Fake Ultimate Hero: Many episodes features this, as Conan's deductions are revealed in the voice of the unconscious Kogoro Mouri, building the man's reputation as a detective (despite the fact that Mouri is a mediocre detective at best).
  • Famed In-Story: By the end of the first season, he has gotten a reputation as a meitantei (on the strength of Conan's behind-the-scenes work) and is often recognized by face or name by those around him. Frequently, when Kogoro's name and/or vocation enters conversation, it will provoke reactions of shock in the (not-yet-known-to-be-a) murderer (and/or others with something to hide). Although Kogoro almost never notices, Conan usually does—and this is often his first clue that something is amiss.
  • Fanboy: Of Idol Singer Yoko Okino.
  • Fatal Flaw: A lot of murderers could've gotten away with their crime(s) because of Mouri's frequency to want to close the case as fast as he could.
  • Foil: To Shinichi Kudo aka Conan Edogawa. Both are arrogant, famous detectives. Shinichi is a talented detective who is "missing", but despite his great intellect, he has trouble with understanding people's feelings. Kogoro is a clueless detective who only becomes a truly good one when a case is an important to him, but has shown a better sense of interpersonal relationships than Shinichi.
  • The Gambling Addict: He often makes bets on horse races or plays pachinko. He ends up losing most of the time.
  • Genius Ditz: When he applies himself, Kogoro can solve a case.
  • Genre Blind: He keeps lecturing and often outright disciplines Conan for putting his nose into important cases on his own, even though his help is what mostly always helps Kogoro and police notice the most important details and clues.
  • Great Detective: Zigzagged. Ar first it seems that Kogoro is an inept detective (and that is for the most part), often trying to quickly solve a case with the fastest resolution (i.e., suicide), leaving Conan to solve the case and (usually) use Kogoro as a dummy. Therefore, his fame as the "Great Detective Sleeping Kogoro" is mostly thanks to Conan. However, in a few cases that are personal to him, he's show a surprising sense of deduction that is may be on par with Shinichi's.
  • Greed: Played for Laughs. People have often gotten Kogoro to do something with the promise of money.
  • Heartbroken Badass: Despite denying it, Eri leaving him and still not coming back, deeply hurts him.
  • Hidden Depths:
    • Kogoro often demonstrates he has a better sense of interpersonal relationships than Shinichi does.
    • Despite his frequent moronic analyses, Kogoro is actually pretty smart when he applies himself.
    • He wrote a screenplay so capable, Yoko Okino agreed to star in it.
  • High-School Sweethearts: With Eri — They have a Childhood Friend Romance which included going to the same high school together before marrying at the age of 20.
  • Idiot Hero: Very close, but it's more of him being impatient and cynical.
  • Jerk with a Heart of Gold: Womanizer? Check. Alcoholic? Check. Giant ego? Double check. Loves his daughter and wife (even if he's estranged with the latter)? Check. Cares for Conan just as much as he would if he were his son? Check. Has a strong sense of justice? You bet he does.
  • Lovable Sex Maniac: Kogoro's lecherous nature often leaves him open to easy manipulation by Ran or Conan (and occasionally clients, murderers, or murder victims), and also usually torpedoes every one of Ran's attempts to get him and Eri to reconcile. He never actually seems to take it any farther than ogling or, at most, platonic dating with the objects of his temporary affection. (He also maintains a persistent crush on idol Okino Yoko.) Given that Kogoro's lechery seems more talk than action, and he was presumably monogamous with Eri until they parted after Kogoro had to shoot Eri in the leg to save her life when she was caught in a Hostage Situation in a flashback in The Fourteeth Target, this may just be his way of distancing himself from Eri to keep either one of them from being hurt again.
  • Manchild: Sometimes, his daughter Ran acts more like his wife or mom.
  • Mr. Vice Guy: He has a lot of vices and frequently indulges them, but he's still fundamentally a decent guy. Oddly enough, Kogoro's original voice actor had plenty of experience playing a Lovable Sex Maniac, as he was also the voice actor for City Hunter Ryo Saeba. (In another character's thought balloon in one of the OAVs, Kogoro even used Saeba's Catchphrase "mokkori".)
  • O.O.C. Is Serious Business: Anytime Kogoro stops acting like a comedic, womanizing clown is when a case has gotten serious.
  • Overprotective Dad: Don't you ever dare to look at his beautiful daughter Ran in any way he doesn't like.
  • Papa Wolf: Do not threaten Ran or Conan when he's around, as this is one of the FEW ways to make him act 100% competent. Don't say we didn't warn you, thieves.
  • Parental Substitute: To Conan. While Kogoro seems to be uncaring towards his ward, he does show a Papa Wolf side should Conan be in danger.
  • Parents as People: While he does care for Ran, Kogoro is still an immature man with issues he has yet to work out.
  • Private Detective: Most of the detective characters in this series are Amateur Sleuths, Kogoro is one of the few who makes his living as a detective. Before Conan moved in, he wasn't exactly successful at it, however.
  • Promoted Fanboy: In-Universe. Upon solving a case for her and becoming increasingly famous as a detective, he frequently received merchandise and invitations to various events from Yoko. He even got to make a guest appearance in her cooking show and would have starred in another show hosted by her if it hadn't got the axe.
  • Real Men Wear Pink: He's a HUGE fan of Yoko Okino.
  • Red Baron: "Sleeping Kogoro." This of course refers to the effect of Conan's sedation dart, but is also a Shout-Out to Katsura Kogoro (aka Kido Takayoshi), who was also known as the "Fleeing Kogoro."
  • Sad Clown: It's heavily implied that Kogoro's constant flirting (which is played for laughs) with other women is just a way to deal with the pain of not being with Eri.
  • Sharp-Dressed Man: While he likes to slouch around unkempt in his apartment when alone, he can change into an exquisite suit within seconds when a client or a beautiful woman shows up at his doorstep. As his fame as a detective increases, he adopts this appearance permanently.
  • Shipping Torpedo: Downplayed. Kogoro doesn't actively try to wane Ran's love for Shinichi, but he has often advised her to give up on him.
  • Single-Target Sexuality: Don't let his flirting with other women fool you. That's only to mask his despair from being separated from his beloved wife, Eri.
  • Small Name, Big Ego: Though, in his defense, Conan lets him take the credit for solving the cases.
  • Small Role, Big Impact: Kogoro indirectly lead to Shinichi and Ran first meeting each other, by accidentally breaking Ran's cherry blossom-shaped daycare tag. She tried to make one made of paper and Shinichi asked her for one for himself.
  • Smart Ball: Depending on your point of view, Kogoro could also be said to catch this ball a few times over the course of the series whenever he actually manages to get a deduction right. Well-seen in the end of the Scuba Driving episode, and in the episode where he fell asleep on the train. (He actually had it solved - the only reason Conan had to step in was because he fell unconscious.) His most shining moment, however comes in "The Unseen Suspect", where he flat-out gets something right that Conan got wrong (granted, Conan smuggled in a few hints about the actual murder method, but he never foresaw that two of the suspects were father and daughter. Kogoro did).
  • Smoking Is Cool: Kogoro is a heavy smoker, and is usually seen with a cigarette in his mouth; he even tries to invoke this image a few times when showing off. And while he may be a buffoon at times, Kogoro is capable of being a threat when pushed and has often showed to have the deductive skills like the protagonist when he applies himself.
  • Thou Shalt Not Kill: Said word for word when he delivers an awesome “The Reason You Suck” Speech to a college friend who killed another college friend.
    "You're right, old pal. I'll never understand no matter the reason what drives someone to murder. And I don't think I want to."
  • Tranquil Fury: Kogoro does have a serious side which only emerges when the case has personal importance to him, such as when Eri and Ran are involved. When this happens, Kogoro's entire personality and demeanor changes and he begins acting professionally, demonstrating improved deductive skills and cunning.
  • Tritagonist: Of the entire series.
  • Unsympathetic Comedy Protagonist: In the early seasons/volumes he regularly punched, kicked, and harshly berated Conan, who remember, despite actually being 17, is in the body of a 7-year-old. Thankfully, this gag has largely disappeared in recent years.
  • Wacky Parent, Serious Child: The Manchild Wacky Parent to Ran's Cute Bruiser Serious Child.
  • Why Did It Have to Be Snakes?: In the movies and filler cases, Kogoro suffers from a mild acrophobia (fear of heights) and is quite uncomfortable in high settings where he has the chance to see how high up he is. He does not have this fear in the manga.
  • Would Hurt a Child: Played for Laughs. In the earlier chapters/episodes, he would yell at, throw, and even punch Conan for simply opening his mouth. He even went as far as placing his fist on Conan's head and saying "Killing move... DRILL PUNCH!" and delivering the noogie from hell.

    Heiji Hattori 
https://static.tvtropes.org/pmwiki/pub/images/img3_283.png
Voiced by Ryo Horikawa (JP), Humberto Amor (first Latin American Spanish dub), Luciano Fox (third Latin American Spanish dub)

The high-school detective of Osaka who serves as Shinichi's main rival. Heiji eventually learns of Shinichi becoming Edogawa Conan and decides to keep it a secret, but is kept in the loop on the latest information regarding the Black Organization. He and Shinichi become close friends as the series moves along, and are always seen together when they're solving cases, or talking about girls.

A majority of cases whenever Heiji teams up with Shinichi deal with strange killings that involve the appearance of a renowned monster. He also becomes extremely determined to one-up Shinichi's London confession to Ran by creating an even better setting to one day confess his love to his childhood friend, Kazuha.

Mandatory naming note: Hattori came from Inspector Hattori of Tantei Monogatari who worked with Kudo Shunsaku. Heiji came from Zenigata Heiji, a fictional police officer in the Edo era.

Dub Name Change: Harley Hartwell.


  • Accidental Pervert: He told Kazuha to take her clothes off. She was shocked for a moment, while Heiji was attempting to undo her clothes, and slapped him. The reason was that she was knocked out earlier with a stun-gun and he was looking for a small burn mark.
  • The Ace: A famous teen detective. Captain of his high school's kendo team. And a Chick Magnet.
  • Adaptation Dye-Job: Initially, in the anime his eyes appeared dark green, but are now blue.
  • Adorkable: A mystery loving Otaku with a thick Kansai Dialect, who has a hard time expressing his feelings for the girl he loves.
  • Affectionate Nickname: He's affectionately nicknamed "Hei-chan" by Ohtaki.
  • Alliterative Name: Heiji Hattori. Also applies with his Dub Name Change.
  • Always Second Best: When Heiji and Shinichi work together, they're each other's equal and will often arrive at the same conclusions. But when they compete with each other or their deductions differ, Shinichi usually wins.
  • Amateur Sleuth: Heiji is a 17-year-old detective from Osaka.
  • Ambiguous Disorder: Heiji is really thick about other people's feelings, bad at picking up social cues, and extremely awkward a lot of the time. He can't lie without stuttering and giggling like an idiot, and he latches onto ideas or interests and does not let them go. For example, when he first became friends with Conan, he talked about Shinichi SO incessantly that his childhood friend believes him to have a girlfriend in Tokyo with the last name Kudo. He's also extremely adept at remembering little details and noticing anything out of the ordinary, no matter how minor. Other than that, he sometimes shows unhealthy excitement when there's a case to investigate. There's one instance when he cheerfully (or enthusiastically, depend on how you see this) announce to Kogoro and Conan that he has a murder case to investigate. This prompted Kazuha to called him out on this, reminded him that he shouldn't be excited about other people's death.
  • Ambiguously Brown: He's clearly Japanese, and he inherited his dark skin from his grandfather, but we don't know ultimately what that comes from.
  • Awesomeness by Analysis: Like Shinichi, he has a keen eye for details, and can spot any unusual aspects in a case that most people tend to ignore or not take into account. He repeatedly demonstrates the ability to recall every detail of an investigation, and may have a photographic memory to manage such perfect recall so consistently. Heiji's fastidious attention to detail allows him to notice minor inconsistencies in crime scenes and suspect testimony.
  • Badass Biker: Shown in full extent in the non-canonical third movie.
  • Badass Bookworm: Heiji has an extraordinarily broad and deep knowledge of many subjects and trivia that help him solve cases. Come a fight, he can easily hold his own with Kendo.
  • Belligerent Sexual Tension: With Kazuha — they have a classic Slap-Slap-Kiss relationship and fell in love with one another at some point.
  • Betty and Veronica: The "Archie" for Kazuha's tomboyish, Hot-Blooded childhood friend "Betty" and Momiji's mysterious, girly, ojou "Veronica". Subverted in that the promise Heiji made with Momiji wasn't of marriage and he's already in love with Kazuha.
  • Beware the Silly Ones: Heiji is a light-hearted jokester and loves to pull pranks (especially on Conan), but he's still a competent detective with master kendo skills.
  • Big Brother Mentor: In one arc, he lends the Detective Boys his help in attempting to solve a mystery before Conan does. He also has a photo he got of himself and Conan, tricked into bowing in front of him, to claim he's this to Conan in particular.
  • Big Ol' Eyebrows: Inherited from his father.
  • Birds of a Feather:
  • Blade Run: Was able to pull this off when confronted by a murderer who was about to kill him.
  • Bromantic Foil: With Shinichi: Heiji is a dark-skinned Osakan who lives with both of his parents, who are very strict (especially his dad whose approach is Tough Love). It took some time during the series, off-screen, to realize his feelings for Kazuha, and he's still not aware of her mutual feelings for him. Plus, Heiji has amazing kendo skills and is on his school's team; Shinichi is a light-skinned Tokyoite who lives (before turning into Conan) by himself, raised by laid-back parents (especially his dad). He fell for Ran first sight when they were preschoolers (way before she realized her feelings for him), and he's aware of her feelings for him. Also, while Shinichi has incredible soccer skills, he isn't (or wasn't) in his high school's soccer club.
  • Brutal Honesty: Like his rival, Shinichi, Heiji doesn't shy away from his honesty, no matter how insensitive it may be.
  • Cannot Spit It Out: Heiji has a hard time expressing his feelings for Kazuha. The one time he did it was in the heat of the moment and he pretended it didn't happen; not out of nerves but because he wanted to express his feelings in a more romantic environment.
  • Catchphrase: "Ahou," Kansai Regional Accent version of baka.
  • Chained Heat: With Kazuha. When they were kids, they got handcuffed while playing with a pair that belonged to Heiji's policeman dad. They spent a whole a day like that, and when they were released Heiji kept an amulet made with a piece of said 'cuffs. Which would later become a Pocket Protector, and save Conan from being stabbed to death. As teenagers, they got handcuffed together again, this time held as hostages and almost murdered for being potential witnesses.
  • Character Development:
    • During the "Bond of Fire" case, Heiji questions Conan if they were right in stopping the culprit from committing suicide, leading to the latter responding that if a detective knows a criminal is about to commit suicide and does nothing to stop it, then the detective is no better than a murderer. Heiji takes to this heart, as evidenced by him stopping the serial murderer in the "Stabbed Wallet" case from committing suicide.
    • His relationship with Shinichi/Conan from his end. In Heiji's first appearance, he traveled all the way to Tokyo to challenge Shinichi Kudo to a deduction battle so he could win and show he was the superior detective of the two. After Shinichi solves the case (which included correcting Heiji's wrong assumptions), the Tokyoite detective then gives a short speech to the Osakan that there's no such thing as the superior or inferior detective, only the truth; Heiji is left both speechless and amazed. Throughout his subsequent appearances,(which involved deducing "Conan's" real identity), Heiji may have kept his competitiveness towards his fellow detective, but he now considers Shinichi/Conan to be his partner and best friend, willing to do anything to ensure his happiness and safety.
  • Chick Magnet: He has shown to be popular with girls due to his good looks, position as kendo captain at his high school, and his fame as a high school detective.
    • The most prominent girl who is attracted to him is Kazuha, who is Heiji's main love interest.
    • Natsuki Koshimizu from the "Detective Koshien" arc possibly took an interest in Heiji given her statement to him about liking his Hot-Blooded nature.
    • During one of his kendo tournaments, several girls tried to flirt with him but he had switched his gear with another team member to make a last minute call to Conan to visit his match.
    • In the non-canon Magic File 4: The Osaka Okonomiyaki Killer several girls came to ask for his autograph.
    • In the non-canon OVA 9, he was referred to as a "lady killer", but that turned out to be Conan's dream.
    • Momiji Ooka is dead set on marrying Heiji.
  • Childhood Friend Romance: With Kazuha — they've known each other since they were kids and now have romantic feelings for each other.
  • Childhood Marriage Promise: Subverted. Throughout most of the 21st movie, everyone believes Heiji made one with Momiji when they were children. In actuality, he won against her in a karuta game, and she was crying about her loss, and in an attempt to console her, he asked her to make a promise with him that she would get stronger. However, Momiji misheard what Heiji said, and thought it was a proposal.
  • Chivalrous Pervert: Downplayed. Heiji is able to deduct what kind of swimsuits girls are wearing, but that's about as far it goes. He's nowhere near as bad as Kogoro.
  • Chronic Hero Syndrome: If he can prevent another death, Heiji will do all he can to prevent it.
  • Crazy Jealous Guy: Like how Shinichi acts towards Ran, Heiji really doesn't like it when a guy looks like he has an interest in Kazuha. When this happens, Heiji is unable to concentrate on the case at hand and he doesn't even like it when she talks about or talks to another man in a perceived flirtatious manner (i.e. Kazuha calling Shinichi Kudo "really smart", talking to a police officer for directions).
  • Declaration of Protection: Heiji makes a silent solemn promise to Kazuha that she will never get hurt when she's with him.
    Heiji: "Fool. You’re too naive. I will never… never… let you be hurt."
  • Defeat Means Friendship: Heiji's friendship with Shinichi began after the latter managed to get the right deduction in the murder case in the former's first appearance.
  • Determinator: Not only did he refuse to let go of Kazuha while they were hanging off the edge of a cliff after she'd stabbed him in the hand to try and make him let go of her , he somehow managed to pull themselves back up off screen.
  • Ditzy Genius: While a bit controversial, Heiji is sometimes thought as such. He's a brilliant detective, but can't for the life of him remember to call Shinichi 'Conan' when they're in public. He also has a bit of a Hair-Trigger Temper, particularly when talking to his childhood friend Kazuha. So much so that one fanfiction diagnosed Heiji with Asperger's Syndrome in a fictionalized psych profile.
  • Embarrassing Cover-Up: When Sera is about to find out about Shinichi, who has just recently shrunk back into Conan, Heiji hides him in his backpack. Sera is suspicious about his very large backpack and demand to know what's in it. To prevent her from doing so, Heiji has to convince her that the backpack is full of his Hentai magazines.
  • Fanboy: Heiji is a big fan of Ellery Queen.
  • Fatal Flaw: Despite him knowing the value and necessity of remaining calm in the face of a crime, Heiji tends to be impulsive at times, which tends to cloud his judgment a little. This was discussed directly in the "Detective Koushien" case, when Saguru Hakuba (another Amateur Sleuth) accused Heiji of being a poor detective for disrupting a crime scene in his rush to see if the victim could still be saved. Also, unlike Shinichi, Heiji seems to be more competitive and hot-blooded while solving a case, which sometimes leads him into making a wrong deduction (i.e. the case in his first appearance).
  • Finishing Each Other's Sentences: With Shinichi Kudo/Conan Edogawa — whenever they work together in a case they will often finish each other's deductions, demonstrating not only abilities as detectives, but also their familiarity with each other.
  • Friendly Rivalry: With Shinichi, once Heiji figures out that Kudo and Conan are the same person. They're close friends who clearly respect each other (their minds are often completely in-sync whenever they do work together on cases), but Kudo's ego and Heiji's competitiveness occasionally ends up with them competing to see who can solve a case first.
  • Good Scars, Evil Scars:
    • Heiji has a scar on the back of his hand where his would-be girlfriend Kazuha stabbed him with a pen when they were hanging off a cliff, in a desperate attempt to make him let go of her hand... so as to make it more likely he'd make it to the top without the extra weight. He still held on, and they both lived to tell.
    • He has a scar behind the left ear from being hit during an Oyodo competition.
  • Great Detective: Like his fellow rival and close friend, Shinichi, Heiji's deduction skills have become well-known enough for him to be nicknamed the "Detective of the West".
  • Green-Eyed Epiphany: Downplayed. The biggest moments where Heiji expresses concern over Kazuha that isn't platonic is when she is seen in a perceived romantic moment with another man. But, due to his own cluelessness, he is unaware (at least, initially) of that his jealousy is not platonic as shown during the "Conan and Heiji's Deduction Magic" murder case. However, it's still unknown exactly how Heiji realized his romantic feelings for Kazuha; the seventh movie is a possible interpretation, but it's up in the air if it is considered canon or non-canon.
  • Hairstyle Inertia: His spiky hair has been his main hairstyle since childhood.
  • Hair-Trigger Temper: Matches perfectly with his hot blooded nature. Heiji has a tendency to snap at people, even when they haven't done anything wrong (i.e. he yells at Kazuha for suggesting he take a break from a case and eat).
  • Heroes Prefer Swords: Heiji is a kendo expert. He may disable criminals using an improvised bokken.
  • Heroic Lineage: In one of the non-canon movies, Heiji states that he gets his bravery from his mother.
  • Heterosexual Life-Partners: Becomes this with Shinichi/Conan over time — even though they still have a rivalry, they have a brotherly like relationship with one another. They go to each other for the other's opinion on their deductions and Heiji has, on several occasions, declared himself to be Shinichi's best friend or brother.
  • Hidden Heart of Gold: Heiji will often tell Kazuha to stay out of his investigations because she'll get in the way. In reality, it's because he doesn't want her in danger.
  • Hot-Blooded: Heiji is hotblooded and impulsive to the freaking MAX. It's both a pro (he works nonstop to solve cases and bring justice thanks to his determination) and a con (he either jumps into conclusions or puts himself in needless trouble for it). He frequently called out on this by anyone he meets.
  • Humans Are Flawed: Has this belief as the quote he stated here:
    "Humans are suspicious and jealous creatures. When they see something perfect, they wanna find a flaw."
  • Hypocrite: A rather humorous example. Although he frequently mocks Kazuha for her superstitions and enthusiasm for good-luck charms, Heiji has several times revealed that he puts more trust in them than he would admit. He once dreamed of Shinichi being murdered, and out subsequently insisted that Conan wear his omamori, the good luck charm Kazuha gave him. The omamori ended up saving Shinichi's life by deflecting a knife blow, but Heiji, without his usual protection, was shot in the stomach. In another case, Ran hung a teruterubozu, a charm that's supposed to ensure good weather, in the window so that Conan would have good weather for his field trip the next day. Heiji, however, got up in the middle of the night to take down the teruterubozu so that Conan's field trip would be rained out and he could accompany Heiji on an investigation of the "The Red Horse Among The Flames".
  • Iconic Item: His hat has become his main appearance trademark.
  • Identical Grandson: Heiji has dark, brown skin which he claims is inherited from his grandfather.
  • Identical Stranger: Downplayed. It's very clear on how to tell him and Shinichi apart due to their different skin colors, hairstyles, and speech patterns. But given the art style, they bare a resemblance. And when Heiji disguised himself as Shinichi via putting on make-up, changing his hairstyle and voice pattern to alleviate Ran's suspicions of Conan being Shinichi, they do look a lot alike; see here.
  • The Idiot from Osaka: Prankster sub-type.
  • Idiot Hero: Zigzagged. Heiji has one of the sharpest minds in the series, but he's also Hot-Blooded and barely conceals Shinichi's secret.
  • Improvised Weapon: He often improvised whatever he has for a sword.
  • Insufferable Genius: Like Shinichi, Heiji has a habit of calling people idiot if they do or say something he finds stupid.
  • Jerk with a Heart of Gold: Heiji has been noted on his short fuse, arrogance, an awful sense of sensitivity, and, the most of all, his Hot-Blooded nature. But there's no denying how far he would go to protect his loved ones; besides that, his bravery, sense of justice, and Chronic Hero Syndrome tendencies are on par with Shinichi/Conan.
  • Kansai Dialect: A very thick one, that he has a hard time concealing.
  • Kendo Team Captain: And has apparently done pretty well against the famously tough members of the Osaka PD.
  • Like Parent, Like Child:
    • Heiji has been noted at different times to have inherited his sharp wit from his father.
    • In one of the non-canon movies, he stated he inherited his bravery from his mother.
  • Lovable Jock: Downplayed. He's on his high school's kendo team and is the captain. However, while he's nowhere near being a Jerk Jock, his arrogant and hot-tempered attitude makes it hard to see his "lovable" side.
  • Love Confession: Wants to give a proper, romantic setting to confess his feelings for Kazuha.
  • Master Swordsman: Of the kendo variety. See Kendo Team Captain for more details.
  • Minored In Ass Kicking: Downplayed. He is more hotheaded than the other high school detectives (a fact remarked upon in the series), but he always keeps using his brains, confronting armed killers with his logical conclusions rather than just knocking them out and calling the police. Attack him or his friends, though, and you'll find out just who can beat the entire police kendo club of Oosaka. Or stop a sword with a cell phone.
  • Nice Hat: His trademark "Sax" hat.
  • No Social Skills: Possibly even worse than Shinichi/Conan's. He once got excited over the prospect of someone being dead, without taking into account the potential feelings of the victims's loved ones or just the proper decency to show someone who has just been murdered.
  • Obfuscating Stupidity: He made repeated use of this, particularly drawing on his "Osakanisms" to cover up whenever he uses Conan's real name by accident.
  • Oblivious to Love: Heiji is apparently, utterly incapable of realizing his feelings for Kazuha or vice versa; even going so far as to believe the jealousy he felt when she flirted with a magician was just a leader's concern for his follower. Till the Drug Trading Case, anyway.
  • Photographic Memory: Like the other "geniuses" of Detective Conan, Heiji has shown himself to have an eidetic memory, capable of remembering complex letter and number sequences at only a glance, such as when he was able to solve a code in his head during the "Heiji and Kazuha in Grave Danger" arc, and even reproduce another message using the same code to text to Conan.
  • The Prankster: Likes to pull childish, but harmless tricks on either Conan/Shinichi or Kazuha.
  • Pride: As a detective and when talking about Osaka, for either trying to one-up Shinichi/Conan in deduction or bragging about how Osaka is better than Tokyo, respectively.
  • Private Detective: Heiji will tackle a case handed to him, but he's more of a Amateur Sleuth.
  • Red Baron: Known as "The Detective of the West" for being a famous and skilled Amateur Sleuth from Osaka.
  • Red Oni, Blue Oni: The rash, Hot-Blooded Red Oni to Shinichi/Conan's calm, somewhat more standoffish Blue Oni.
  • Running Gag:
    • Cases with Heiji usually involve falling corpses, stock horror monsters (not real ones) or a combination of the two.
    • Heiji tends to get physically roughed up during some of the cases he gets involved in (either Played for Laughs or Played for Drama).
  • Save the Villain: Adopts this mindset after hearing Conan's poignant reason as to why he refused to let the murder culprit from "Bond of Fire" case commit suicide.
  • Scars Are Forever: The scars he received (as stated under Good Scars, Evil Scars) are still around in.
  • Secret Keeper: He was the first one to deduct that Conan's true identity was Shinichi Kudo. A rather bad one, however, constantly blurting out Conan's real identity and then scrambling to cover it up.
  • Sensitive Guy and Manly Man: The Manly Man to Shinichi's Sensitive Guy. Zig-Zagged somewhat: Heiji is more emotionally driven due to his Hot-Blooded nature, but he's also noticeably more thick when it comes to appreciating someone's feelings. Shinichi on the other hand isn't a very sensitive person as far as his own emotions go, but knows when to keep his head cool and in a romantic sense, figured out his feelings for Ran first; a rarity in Shonen protagonists. He also is fairly good at deducing what other people are feeling when he makes an effort to observe them.
  • Shipper on Deck: Even with his teasing, Heiji genuinely wants Shinichi (Conan) and Ran to become a couple. He once suggested that Shinichi tell Ran the truth about the Black Organization to ease both of their suffering.
  • Single-Target Sexuality: In a reverse situation from Shinichi and Ran, it took Heiji a while to realize his romantic feelings for Kazuha. However, even before coming to realize his feelings, Heiji has never shown interest in any other girl.
  • Slap-Slap-Kiss: His whole dynamic with Kazuha — They argue and call each other idiot, but they have a deep connection and love each other dearly.
  • Spirited Competitor: Heiji possesses a competitive spirit that is first seen in his introductory episode and other times when someone else (usually Conan) engage in a deduction battle.
  • Straight Man and Wise Guy: The light-hearted, jokester Wise Guy to Shinichi's serious, deadpan Straight Man.
  • Strong Family Resemblance: Heiji's face is more align with his mother's. The only differences are his dark skin and Big Ol' Eyebrows, traits he inherited from his father.
  • Surprisingly Good English: Heiji speaks fluent English and in the anime, his accent barely shows. This is attributed to the fact his seiyuu Ryo Horikawa is fluent in English himself.
  • Tall, Dark, and Handsome: Like Shinichi, Heiji is a Chick Magnet, roughly the same height as his rival, and has black hair.
  • Tall, Dark, and Snarky: Fits the criteria for Tall, Dark, and Handsome and also has been known to make sarcastic remarks.
  • Teen Genius: Heiji has shown himself to have an eidetic memory, capable of remembering complex letter and number sequences at only a glance, such as when he was able to solve a code in his head during the "Heiji and Kazuha in Grave Danger" arc, and even reproduce another message using the same code to text to Conan.
  • Thinking Tic: He usually wears his cap with its visor pointed backward, but during a case, he turns the visor forward. At the end of whatever case he's on, Heiji turn the visor backwards again.
  • Trademark Favorite Food: One of the OVAs shows Heiji really enjoys okonomiyaki.
  • Tsundere: Given his hot-blooded and jerkass tendencies towards Kazuha while trying to hide his feelings for her, Heiji is definitely a Type A Tsundere. See Violently Protective Girlfriend below as well.
  • Undying Loyalty: Like Shinichi/Conan, Heiji will do anything to protect his loved ones from harm.
  • Violently Protective Girlfriend: Gender-flipped. Heiji has shown his extreme dislike of men flirting with Kazuha, but if anyone so much as threatens her, or makes him think she's being threatened, Heiji will kick their ass. In fact, this is what led to Heiji's confession.
    "Whatcha doin' to MY Kazuha!!?"
  • "Well Done, Son!" Guy: Implied. While their relationship isn't thoroughly explored, Heiji wants to be a detective like his father.

    Ai Haibara/Shiho Miyano/Sherry 
https://static.tvtropes.org/pmwiki/pub/images/shiho_ai87654.png
Voiced by Megumi Hayashibara (JP) / Brina Palencia (EN), Carmen Amadori and María Luisa Benech (third Latin American Spanish dub), Cecilia Gómez (movie 18 onwards, Latin American Spanish dub), Silvia Sarmentera (second European Spanish dub and movies), Kyoka Shibata (Live-Action Drama Actress as Ai Haibara), Yu Kashii (Live-Action Drama Actress as Shiho Miyano)

A young girl whose true identity is Shiho Miyano, aka "Sherry" of the Black Organisation. She is the genius chemist who created the APTX-4869 drug that turned Shinichi into a six-year old boy. After she is imprisoned by the Black Organisation for being related to the traitor, Akemi Miyano, Shiho attempted suicide with a dose of APTX-4869 but was instead de-aged as well. Using her newly-shrunken body to escape and go into hiding as "Ai Haibara", Shiho is taken in by Shinichi's next door neighbour and uses her condition to live out the innocent childhood she never had. She joins the Detective Boys as a way to make amends for her past crimes, and works on an APTX-4869 antidote for Shinichi.

Mandatory naming note: Haibara came from Cordelia Gray; Haibara literally meant Grayfield. Ai came from flipping the V in V.I. Warshawski— the kanji usually associated with the sound "Ai" means love, but she took the alternative for "sorrow."

Dub Name Change: Anita Hailey (Viz Media); Vi Graythorn (Funimation)


  • Acting Your Intellectual Age: Since Haibara doesn't put any effort in deliberately acting like a child, she appears to be this to in-universe bystanders.
  • Adorably Precocious Child: Since she's really 18-years-old, Haibara often appears quite mature in front of people.
  • All of the Other Reindeer: Got her education in America, where she was picked on for her Japanese features.
  • Animal Motifs: At one point, she compared herself to sharks in an unflattering manner.
  • The Atoner: Ai now works to find the antidote for the poisonous drug she created and to take down the Black Organization.
  • Because You Were Nice to Me:
    • A combination of Shinichi/Conan's Declaration of Protection, the natural friendliness of the Detective Boys, and Professor Agasa's fatherly nature allowed Ai to break out of her shell little by little.
    • Ran protecting her from being killed by Vermouth had Ai think of Ran as a Living Emotional Crutch and Morality Pet.
  • Better to Die than Be Killed: She attempted this when she was locked up for betraying The Syndicate, rather than facing execution. She took a poisonous drug she created, but instead of dying she suffered its ''other'' effect, which shrank her to the size of a six-year old little girl. Because of that, she was able to escape and... you know the idea.
  • Big Sister Instinct: She is quite protective over the Detective Boys, especially Ayumi.
  • Big Sister Worship: Haibara truly loved her sister, and was devastated by her death.
  • Breakout Character: Introduced more later in the manga, Ai has become one of most important characters in the series with more screentime. She is also very loved by fans thanks to her personality and the Ship Tease with Conan. It's saying something that she consistently outranks the other female lead Ran in popularity polls.
  • Broken Ace: She was one of the top scientists in her field...too bad it was with the Black Organization. Besides that, Haibara was bullied while studying in America, raised in the Black Organization, only heard bad things about both parents and hardly saw her beloved sister.
  • Broken Bird: Her choice of a pseudonym underscores this. As said before, the kanji for "Ai" doesn't mean "love", but "sorrow".
  • But Not Too Foreign: Shiho's mother Elena was British while her father Atsushi was Japanese.
  • Character Development: Over the course of the series, Haibara loses her suicidal thoughts and stops running away from the B.O.
  • The Chessmaster: The stint in Volume 26 of the manga established that.
  • Chekhov's Gunman: Shiho's silhouette appeared in chapter 16, when Akemi mentioned her younger sister during her last conversation with Gin. Ai makes then a proper appearance exactly 160 chapters later.
  • Child Prodigy: Implied. When Shuuichi Akai joined the Organization as an undercover agent, Ai was just thirteen years old. At that time, she was already important enough to the Organization as a scientist that getting close to her gave Akai the connections and influence he needed to successfully infiltrate their inner ranks.
  • Chronic Hero Syndrome: Denies having this and claims that she, unlike Conan, is not interested in such abstract concepts as 'justice'. Gin, however, predicts that once she has heard about a murder the Organization has planned, she WILL show up to try and stop it because that's the kind of person she is. He's right.
  • Code Name: Hers was "Sherry", which indicates that she used to be a rather important member of the Black Organization. Since she was the first female member introduced to have a code name, the naming pattern between male and female members was also established with her introduction. In the episode ONE special, we also learn that members of the Black Organization sign with their code names rather than with their real names.
  • Cower Power: When Haibara is frightened, such as when she senses someone from the Organization close by, she will grab onto and hide behind someone. Most often this is Conan or Professor Agasa. The "Red, White, Yellow" case featured her grabbing Mitsuhiko so hard she accidentally hurt him and the Mystery Train had her clinging tightly to Ran.
  • Creepy Child: Conan is much better at coming across as a normal kid than she is, which is saying something. In her first appearance, she terrified a gang leader by picking up the woman's gun and shooting her at point blank range, intentionally missing only by a short margin.
  • Cuteness Proximity: Animals bring out the "sugar" of her Sugar-and-Ice Personality.
  • The Cynic: Being raised in the dark and mysterious Black Organization really took a toll on Haibara's sense of hope, justice, and innocence.
  • Damsel in Distress: Occasionally, for example when Conan has to save her from Pisco, Gin and Vodka.
  • Dark and Troubled Past: Inevitable, having been raised by the Organization.
  • Death Seeker: Believing that it's only a matter of time for The Syndicate to find her and kill everyone she's associated with, she willingly remains in a bus that has a bomb about to go off because she doesn't want to put those around her in danger. Conan pulls her out in the nick of time. In a later volume, she surrenders herself to Vermouth in exchange for her promise that no one else will be harmed, but is rescued again.
  • Defrosting Ice Queen: Cynical by nature and experience, Haibara preferred to keep everyone around her at arm's length at first and was extremely reluctant to show her face at public events. It takes time for Agasa, Ran and the Detective Boys to get through to her, but she gradually becomes friendlier towards them and more willing to take measures to keep them safe from harm.
  • Deliberately Cute Child: Averted. Unlike Conan, Haibara never bothers with this. The one time she did, in one of the movies, it freaked Conan out something fierce.
  • Determinator: Played for Laughs, when she tells Conan that she spent the entire night finding and killing a cockroach in Agasa's house.
  • Eating Lunch Alone: She claimed she was that when she was in school. Not surprising.
  • Fangirl:
    • In fashion, she likes the products from Prada and Fusae Campbell.
    • Haibara is a big fan of Big Osaka in general and of the player Ryusuke Higo in particular, so much so that in his later appearances, she actually acts more like the child she appears to be and not the de-aged scientist she really is.
  • The Fashionista: A milder example. When not at work, she nearly always read fashion magazines. She also sometimes demands expensive purses or other fashion items in return for favors.
  • Find the Cure!: After swallowing the APTX pill, getting shrunk, escaping the syndicate, and meeting fellow APTX victim, Conan, Haibara has made it priority to find a cure to reverse back to their true ages.
  • Foil: To Shinichi Kudo aka Conan Edogawa. Both are highly intelligent APTX victims with a Friendless Background with some personal tie to the Black Organization, have given themselves a shark motif. Shinichi is an attention-seeking, over-confident teen detective who was raised by an eccentric, but loving family, and was forced to take the APTX drug as he was a witness to a crime, and is desperate for a cure. And while he didn't have a lot of close friends (sans Ran) due to his blunt nature, he was still popular due to his athleticism, detective work, and natural charm. Due to his own arrogance, Shinichi initially would recklessly follow any lead he could find before learning to be more cautious after some pretty close calls. As for him comparing himself, or detectives, as sharks, it was like a Badass Boast; Shiho is a reclusive, self-depricating teen scientist whose parents died when she was young and she was hardly able to see her sister, leaving her to be raised by the cold and unfeeling Black Organization members, and she willingly took the APTX drug to commit suicide after she learned of her sister's death, and is not in a hurry to change back. The reason for her friendless childhood was because many of peers would make fun of her biracial features. Due to her fear, Shiho initially would try to commit suicide instead of being caught but realizes she can't keep running from them. When she compared herself to a shark, it was in an unflattering style.
  • Fountain of Youth: The APTX-4869 drug regressed Shiho's body by around ten years, causing the Teen Genius to live in a first grader's body, who would be known as "Ai Haibara". On the other hand, APTX-4869 is employed as a poison and is generally successful.
  • Friendless Background: Her sister was the only person close to her before she was shrunk and met Agasa, Conan and the Detective Boys. It's one of the reasons why she's much less eager to change back than Conan.
  • Friend to All Living Things: Haibara is a huge animal lover and said animals take an instant liking to her.
  • Guile Heroine: Justified. She was raised in an organization that specializes in manipulation. Thankfully, she uses it for good intentions.
  • Heel–Face Turn: Before she appears, no less. Though it's questionable how much of a bad guy she was in the first place, as she might not have had much choice in working for the Organization, seeing how both her parents were members and the Organization was not willing to let someone with her potential slip away.
  • Heroic BSoD: Haibara experiences several of these when major shenanigans involving athlete Ryusuke Higo take place, such as the incident described under "Not So Above It All" below.
  • Hidden Eyes: When we see her adult form in flashbacks, her eyes are usually covered by Blinding Bangs or otherwise hidden. Not when she temporarily returns to her old body in the present story, though.
  • Hidden Heart of Gold: Justifies many of her more altruistic acts with pragmatic, self-serving motives.
  • Hopeless Suitor: It's strongly implied she has romantic feelings for Shinichi/Conan, but given how open he is with his love for and only for Ran, she most likely keeps her feelings to herself.
  • Hot Scientist: In her older form. As a child, her classmates find her very cute, but of course have no idea that she's a scientist.
  • I Just Want to Be Normal: One reason why she is in no hurry to get back her old body and become "Shiho Miyano" again is because she has a happier, more normal life as "Ai Haibara".
  • Improbable Age: Reconstructed. She led the Organization's poison lab before she was shrunk— that was when she was 18. She does not enjoy the Intelligence Equals Isolation part of her past life, in addition to being separated from Akemi. She took this chance to re-live the childhood that she deprived when she was young and feels like that— this is why she's not in an urge to take the antidote herself.
  • Intelligence Equals Isolation: One of the reasons she's not willing to change back that soon.
  • Jerk with a Heart of Gold: Haibara has a jaded demeanor, standoffish-like nature, and dry sarcasm. Despite all that, she can be kind and caring, though usually more to animals than people.
  • Lady and Knight: A platonic version with Shuichi Akai with her as the Lady. When the already adult Akai gave a Declaration of Protection to her while masquerading as Subaru Okiya, he explicitly compared her to a princess and himself to a knight that would protect her. Subverted in that there are no romantic undertones because not only Ai is much younger than Akai and is Older Than They Look thanks to a Fountain of Youth, but she is the sister of his dead girlfriend Akemi, who is implied to have asked him to protect Ai before being murdered.
  • Last-Name Basis: She was this at school, which unsettles Ayumi. Ayumi later gets permission to call her by her first name, but not the other Detective Boys.
  • Little Miss Snarker: She mainly snarks Conan. On occasion she's done this to Agasa as well, at least where his eating habits are concerned.
  • Locked Out of the Loop: Conan regularly keeps her clear of his investigations into the Black Organization when he can help it. This has backfired, such as when Haibara's sudden appearance during the first encounter with Vermouth derailed Conan's plan. It worked more in their favor in the Mystery Train arc, where it made sure Haibara didn't take any actions that would rouse enemy suspicion before it was time to bring her into the plan.
  • Loner-Turned-Friend: The Detective Boys' friendship eventually turns her into this. When she was first introduced, she would often stay off to the side of whatever activity the Detective Boys were doing while later arcs, such as the Sweet and Cold Delivery Service arc, open with her playing soccer with them, and even mentally Calling Your Attacks as she's about to do one of Higo's moves.
  • Martyr Without a Cause: In contrast to Conan, who is quick to risk his life to protect others from danger, Haibara is quick to sacrifice it. Early in her involvement she intended to stay aboard a bus rigged to explode, viewing herself as a danger to her new friends. Character Development gets her past much of this, but it still forms enough of her personality that both Vermouth and Conan count on it aboard the Mystery Train to predict her behavior. They correctly deduce that she would find some place private to take a temporary antidote so that when (not if) she died it would not be in her child form and prevent the Detective Boys from kicking up a fuss that might inadvertently catch the Organization's eye.
  • Master of the Mixed Message: As it stands, it's a mystery whether Haibara has romantic feelings for Shinichi/Conan or not. She first tells him something that can be seen as romantic but immediately declares she was joking. Then, there's her apparent jealousy of Ran (Shinichi/Conan's only Love Interest), but that could also be seen as her not wanting to be close to someone who strongly resembled her dead sister and her usual coldness. However, it's up in the air at this point.
  • The Mind Is a Plaything of the Body: Even more averted than Conan, as the drug only regressed her physically and she makes no attempt to play the Deliberately Cute Child card like Conan does.
  • Mixed Ancestry: Ai/Shiho is half-English (mother's side) and half-Japanese (father's side).
  • New Transfer Student: How she made her official introduction as "the first transfer student since Conan arrived".
  • Non-Action Snarker: In a series where most women are at least adept at some form of martial arts, she stands out as having very little means of self-defense. She is a pretty crack shot with guns, especially pistols, but she just doesn't get many opportunities to use them.
  • Not a Morning Person: She yawns a lot in the morning due to regularly pulling all-nighters in the lab.
  • Not So Above It All: Usually either serious or snarky, but she does have the odd moment of silliness. Soccer player Ryosuke Higo in particular brings this out in her. Haibara claims she simply admires him, but her actions are much more like those of a young lovestruck girl. Chapters 925-927 features Ai suffering a borderline BSOD when she learns that Higo might have hooked up with Yoko Okino, and when both Yoko and Higo are involved in a case, she butts heads with Kogoro and Yoko more than once. Professor Agasa has said Haibara's attitude regarding Higo reminds him that there's still an otherwise normal girl under that cold exterior.
  • Not So Stoic: First seen when she breaks down in front of Conan because he could not save her sister from being killed by the Organization.
  • Older Alter Ego: Inverted. Like Conan, she's really 18-year-old Shiho Miyano shrunken into an 8-year-old via the APTX pill. As such, "Ai Haibara" is her younger alter-ego.
  • Older Than She Looks: Shrunk in the same manner as Shinichi, down to a 6-year-old's body. Played for Laughs when Conan first asks her real age. She flatly states 84, throwing Conan for a loop. She only kept up the joke for one panel, but it was worth it to see Conan's surprise and bafflement.
  • Pint-Sized Powerhouse: Even in her shrunken state, she's been shown to trip and drop men who weigh five times as much as her, and when forced to revert to her true age to save the Shounen Tanteidan from a burning cabin, she effortlessly destroyed the door with an axe.
  • The Quiet One: Haibara tends to be quiet, though this may be due to her caution to keep herself hidden from the Black Organization.
  • Secret Identity: Her real name is Shiho Miyano.
  • Secret Keeper: One of the few people who knows that Conan is Shinichi, she also hid this from The Syndicate while she was still a member because she thought him an interesting subject to watch.
  • Sexier Alter Ego: Downplayed. As Shihio, she was already considered "sexy", while her younger ego is more along the lines of "cute".
  • A Shared Suffering: She has confessed to Conan that having him around in the same situation as her is why she can stand being a six-year-old.
  • Shipper on Deck:
    • She gives a knowing, sly smirk to Agasa (along with the rest of the Detective Boys) after the Profesor's meeting with his First Love, Fusae Campbell-Kinoshita.
    • She may not be as much of a Satou and Takagi shipper as the Detective Boys, but she doesn't mind them getting together.
    • In her own way she was very interested in the deals of Kobayashi and Shiratori.
      "To Inspector Shiratori, Kobayashi-sensei is his "girl of destiny" [...] It's irritating. To fail to express his feelings straightforwardly, leaving his girl in the dark... a typical dorama moron."
    • She appears to be a Heiji/Kazuha shipper given she used Heiji's confession to Kazuha as a ringtone for a while.
  • Sins of Our Fathers: And mother. Vermouth has a notable desire to see Haibara dead; the closest she's come to an explanation is that the fault should be blamed on Haibara's parents, Atsushi and Elena, for their 'foolish research' and the fact that Haibara continued it after their deaths.
  • Stepford Snarker: Her Little Miss Snarker persona masks some DEEP issues, starting with the murder of her beloved older sister Akemi, and the constant fear of being found by the The Syndicate.
  • Sugar-and-Ice Personality: When freshly escaped from the Black Organization, she was cynical and pushed others away. Haibara has since defrosted by embracing her new child life and has established strong relationships with Conan, the Detective Boys, Agasa, and Ran.
  • Team Mom: Despite her reserved appearance, she is this for the Detective Boys, ESPECIALLY when the Professor tags along.
  • Teen Genius: She is a biochemical genius, taking up her parents' research work on APTX-4869 for the Black Organization by the age of thirteen after going to school in America. Haibara has also demonstrated knowledge of medicine, recognizing the symptoms of Shiratori's subdural hematoma. Using knowledge of osteology, she also is able to deduce a long decayed woman's ambulatory condition.
  • Took a Level in Cheerfulness: Her time as "Ai Haibara" has made her a happier person, though she still keeps her witty sarcasm.
  • Took a Level in Idealism: Likewise, over time she has become more optimistic and open to Conan's idealistic pursuit of justice...
  • Took a Level in Kindness: ...as well as softening her personality the more time she spends with her friends.
  • Trademark Favorite Food: In the OVA A Secret Order From London, Haibara reveals to Ayumi that she likes sandwiches with a mixture of peanut butter and blueberry jam, from her schooldays in America.
  • Tragic Keepsake: The tapes her deceased mother left for her.
  • Tsundere: Following her outrage towards being Locked Out of the Loop during the Mystery Train arc, Professor Agasa suggested she might an example of this, though Conan claims that she fails the "dere" part.
  • Uncanny Family Resemblance: Which was also a subtle foreshadowing. When Ai was wearing an eyelash, Conan noticed her resemblance to the 'Mysterious Child' from Sera's phone. Later on, it turns out that the 'child' is the shrunk Mary Sera, heavily implied to be Ai and Akemi's relative from their mother Elena's side.
  • Wacky Parent, Serious Child: With Agasa as a Parental Substitute, he and Haibara have this dynamic. She increasingly nags about his unhealthy diet and she is the one who cleans the house and does the laundry. Kogoro jokingly notes in Countdown to Heaven that she acts a lot like Agasa's wife.
  • Wise Beyond Her Years: The Detective Boys always refer to her as "mature and cool".
