    Heiji Hattori
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 is still not aware of her mutual feelings for him. Plus, Heiji has amazing kendo skills and is on the team; Shinichi is a light-skinned Tokyoite who lives (before turning into Conan) by himself, raised by laid-back parents (especially his dad).By middle school, he figured out his romantic feelings for Ran before she did, and is 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.
  • Catch-Phrase: "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 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.
  • Character Tics: 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.
  • 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.
  • 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.
  • 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.
  • Jerkass Façade: 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.
  • 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.
  • 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.

    Kazuha Touyama
Voiced by Yuko Miyamura (JP) Marcela Bordes (first Latin American Spanish dub), Gigliola Mariángel (third Latin American Spanish dub)

Heiji's childhood friend and love-interest who becomes close friends with Ran.

Dub Name Change: Kirsten Thomas (Anime)/ Katrina Tolliver (Wii).
  • Action Girl: Aikido expert. Very helpful when par her with Ran's Karate.
  • Anger Born of Worry: Anytime she gets angry (usually at Heiji), most of the time, it's because she worries for their safety.
  • Badass Adorable: She knows Aikido and is quite cute, especially when talking about Heiji.
  • Badass in Distress: In the Kyoto movie, she was kidnapped and used as a bait for Heiji and Conan. Once she was released by Conan, though, they both helped Heiji in his fight.
  • Belligerent Sexual Tension: With Heiji — they have a classic Slap-Slap-Kiss relationship and fell in love with one another at some point.
  • Betty and Veronica: The tomboyish, Hot-Blooded childhood friend "Betty" to Momiji's mysterious, girly, ojou "Veronica" for Heiji's "Archie". Subverted in that the promise Heiji made with Momiji wasn't of marriage and he's already in love with Kazuha.
  • Birds of a Feather:
    • With Heiji — both are stubborn, Hot-Blooded, have a strong love of Osaka, fathers are in the police force, attract a number of people from the opposite sex, and they have a strong belief in magic (though Heiji refuses to state it out aloud).
    • With Ran — Practitioners of a martial art (aikido for Kazuha, karate for Ran), afraid of the supernatural, love of children, are Dude Magnets but only have eyes for their childhood best friend. And even though they can be exasperated by their love interest's detective work and occasional jerkish side, both think that whenever their "not" boyfriends solving cases look cool when doing so and admire them for their better qualities as well. Also, both of their fathers are connected to some kind of detective/police work.
  • Brutal Honesty: She is highly confrontational, and unafraid of letting others know about her dislike.
  • Cannot Spit It Out: When she finally does get the nerve to do so (mentioning Shinichi's confession to Ran in London), Heiji rushes off to find and tease Conan before she can.
  • Chained Heat: With Heiji. 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.
  • Childhood Friend Romance: With Heiji — they've known each other since they were kids and now have romantic feelings for each other.
  • Clingy Jealous Girl: Played for Laughs in her first appearance where she grilled Ran (who she thought was Shinichi) about how she should treat Heiji. Her next appearance has her being jealous over Ran because she and Heiji wore the same kind of outfit twice. Needless to say, Kazuha can get easily jealous.
  • Daddy's Girl: Kazuha has a close relationship with her dad.
  • Defrosting Ice Queen: Kazuha was rather frosty towards Ran because she thought that Ran may have took an interest in Heiji (they wore the same type of shirt twice). After Ran wordlessly changed shirts to put Kazuha at ease, the Osakan girl realized how nice Ran was and they instantly became friends.
  • Dude Magnet: Similar to Ran, Kazuha has many gentlemen ogling over her. And then there's Heiji...
  • Embarrassing Nickname: Condescendingly nicknamed "Leafy" (Happa-chan) by Momiji.
  • Everybody Has Standards: She gave Heiji a major What the Hell, Hero? moment when he cheerfully (or enthusiastically) proclaimed someone's death.
  • Foil: To Ran — Kazuha lives with both parents (her mother has yet to make an appearance), is a little affectionate, but is capable of a lot, and is classified as a Type A Tsundere. Heiji is physically with her, but their feelings for each other have yet to be spoken. Kazuha is an Aikido expert and uses her hands more when fighting; Ran lives with her father (both her parents are separated), is generally more affectionate, and is classified as a Type B Tsundere. Shinichi is not with her currently, but he's really Conan Edogawa, and because of that her romantic feelings were noticed. She is a karate expert, and implores a lot of kicks when fighting.
  • Friend to All Children: In a side OVA, Kazuha showed a great talent with nursing children and told Heiji she would like to have one someday.
  • Good Luck Charm: She considers the picture of Heiji she carries around as this.
  • Green Eyes: Possibly to show her importance to the show.
  • Hair Decorations: Spices up her ponytail with colorful hairbands.
  • Hairstyle Inertia: Her ponytail hairstyle has been with her since childhood.
  • Heroic Sacrifice: When she and Heiji are hanging precariously off the edge of a cliff, she attempts one and stabs him in the hand to make him let go of her. He doesn't.
  • Heterosexual Life-Partners: Becomes this with Ran over time — They have become close friends since the 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:
    • She may not be on Heiji's level, but Kazuha was able to get his hint of a code in a murder investigation. Before that, she remembered a relatively small detail of how Ran and Heiji wore the same type of t-shirt twice, even though the time between her first and second appearance was a long one.
    • The trailer for the 21th movie shows that Kazuha is proficient in hyakunin issha garuta, good enough to join school competitions. Just like her potential love rival, Momiji Ooka.
  • Hot-Blooded: Though she's more calmer in comparison with Heiji, she can still be passionate and emotional.
  • Jerk with a Heart of Gold: Her first and second appearance has her acting cold and snippy to Ran because of her jealousy-fueled fear that Ran liked Heiji. Then, there's how her Hot-Blooded nature makes her more temper-y. But she is brave, loyal, and friendly, the latter of which showed more after her defrosting.
  • Kansai Dialect: It's not as thick as Heiji's. It helps that her seiyuu is from Kobe.
  • Love Confession: Kazuha tried to do this and managed to carry it through, but Heiji left to go tease Conan about him making his own love confession to Ran as Shinichi.
    "Ya might have already heard this from Kudo-kun, but...In London, apparently Kudo-kun confessed his feelings to Ran-chan.That's why, though I wouldn't have said this...The truth is...The truth is, I also...Since a long time ago...I... I LIKE YA VERY MUCH!"
  • Muscles Are Meaningless: Can effortlessly toss larger criminals with ease.
  • Protective Charm: They aren't real since the genre of the series doesn't include "magic", but Kazuha has a marked belief in spirits, good-luck charms, and other superstitions. Right from her first experience, she displayed her belief in the importance of hers and Heiji's omamori, charms which Kazuha made to protect her and Heiji from harm. A later case shows that Kazuha and her mother (but Kazuha even more so) are apparently well-known in Osaka thanks to the good-luck charms they make, said to be very effective good luck magnets for their owners.
  • Raven Hair, Ivory Skin: Pale skin with raven hair.
  • Red Oni, Blue Oni: The Hot-Blooded, temperamental Red Oni to Ran's calmer, sensitive Blue Oni.
  • Sailor Fuku: Her and Heiji's school in Osaka also favors the seifuku (also a dark blue one) and the gakuran, and they show up wearing them at the start of the Desperate Revival arc.
  • She Cleans Up Nicely: Invoked on her in the seventh movie. In a subversion, this happened to her years ago, when she was a little girl visiting her family in Kyoto and they put her in a fancy kimono. Then little Heiji saw her under the Cherry Blossoms...
  • Shipper on Deck: She ships Shinichi and Ran.
  • Shorttank: Her usual outfit.
  • Single-Target Sexuality: In a reverse situation from Shinichi and Ran, it was Kazuha who realized her feelings for Heiji before he did and has never looked at another guy.
  • Single Woman Seeks Good Man: Kazuha is in love with her childhood best friend Heiji Hattori. To reiterate, Kazuha loves the Osakan detective who has a strong sense of justice and has proven to her time and again that he will do anything to protect her, including get into a brawl.
  • Slap-Slap-Kiss: Her whole dynamic with Heiji — They argue and call each other idiot, but they have a deep connection and love each other dearly.
  • Spanner in the Works: Whenever Heiji has a plan that involves him dressing up as someone else. She knows him that well.
  • Tomboy: More so than Ran. Kazuha's way of dressing ranges from shirt and jeans to (though rarely) dresses.
  • Tomboyish Ponytail: Her trademark hairstyle.
  • Tomboy with a Girly Streak: While Kazuha is more tomboyish than Ran, she does love romance and has a thing for the theatre.
  • Took a Level in Kindness: By the end of her second appearance, Kazuha went from acting coldly to Ran to becoming one of her two heterosexual life partners.
  • Tsundere: Type A this time, meaning she's more temper-y than Ran.

  • Why Did It Have to Be Snakes?: Like Ran, Kazuha has an intense fear over the supernatural.

    Heizo Hattori
Voiced by Takehiro Koyama (JP), Andrew T. Chandler (EN)

Heiji's father and the Police Commissioner of Osaka.

Dub Name Change: Martin Hartwell.
  • Alliterative Name: Heizo Hattori.
  • Awesomeness by Analysis: Heizo possesses a very sharp intellect and observation skills. His intelligence is on par with Yusaku Kudo, given how both fathers are able to solve a case before their sons do; Heizo was able to correctly deduce the culprit in the murder cases that involved Toyotomi's castle. His deduction skills were further demonstrated during a flashback, when he was able to solve case just by listening to the details on phone and give a hint to Heiji.
  • Badass in Charge: Heizo is the highest ranking officer at Osaka Prefectural police Headquarters, and thus has the command of many of the police officers of Osaka.
  • Badass Moustache: His intelligence is on par with Yusaku Kudo and Heizo even has an equally neat-looking moustache.
  • Big Ol' Eyebrows: He's where Heiji inherited his thick eyebrows from.
  • Da Chief: Heizo is the highest ranking officer at the Osaka Prefectural Police Headquarters; he is Superintendent Supervisor (Rank 2).
  • Eyes Always Shut: He rarely opens one, left alone both.
  • Happily Married: Shizuka and Heizo appear to have a good relationship. She is not intimidated by Heizo's fierce personality, and he seems to listen to her.
  • Heterosexual Life-Partners: With Ginshiro Toyama. In fact there friendship is how Kazuha and Heiji became friends with each other and more.
  • Jerkass Façade: In a Tough Love variety. For example, he punched his son in front of many people because of his son's immaturity during a case. But it was revealed later on that he merely punched Heiji for his son to be more aggressive in solving the case and using both Heiji and Conan as a bait, although he apologized later on.
  • Jerkass Has a Point: During his "The Reason You Suck" Speech to Heiji, he makes some accurate points about how his son's hotheadedness and arrogance is hindering the case.
  • Jerk with a Heart of Gold: In spite of his manipulative nature with Heiji, Heizo still loves his son and will protect him with his life.
  • Manipulative Bastard: And not even Kogoro is pleased.
  • Papa Wolf: Heizo will place himself between a dangerous criminal and Heiji in order to protect the latter.
  • Reasonable Authority Figure: As a high-ranked commissioner, his work is mostly a paperwork and negotiations-centered one (unlike what Hollywood and comic books say) so he leaves the action more to people like Touyama or Ohtaki.
  • The Stoic: Contrasting with his son's Hot Bloodedness, Heizo is more serious and cool-headed.
  • Sugar-and-Ice Personality: Heizo does care for and will protect his son, but his brusque and stoic personality leaves him unlikely to say as much, or even if he is proud of Heiji.
  • Tough Love: Ginshiro even lampshades this to Ohtaki on Heizo's relationship with his son.

    Shizuka Hattori, nèe Ikenami
Voiced by Masako Katsuki (JP)

Heiji's beautiful, strong-willed mother.

Dub Name Change: Melinda Hartwell.
  • Action Mom: Her first appearance includes easily subduing the culprit in a murder case. And like her son, Heiji, she is skilled at kendo.
  • Almighty Mom: One of the few persons who can stand up to the sneaky and stubborn Heizo, and doesn't even flinch when her Hot-Blooded son calls her "old woman".
  • Expository Hairstyle Change: She went from a Tomboyish Ponytail in her teen days to a Prim and Proper Bun as an adult.
  • Happily Married: Shizuka and Heizo appear to have a good relationship. She is not intimidated by Heizo's fierce personality, and he seems to listen to her.
  • Housewife: After she's married.
  • Lady of War: Former kendo champion, and has NOT lost her skills.
  • Mama Bear: She spent her first appearance seeing if Kogoro was a good of enough person to hang around Heiji and wouldn't put her son in any danger.
  • Nerves of Steel: Shizuka can remain calm in dangerous situations.
  • Older Than They Look: Is older than Kogoro and Eri, and yet looks quite young.
  • Paper Fan of Doom: She can catch the katana of a person swinging it wildly with just her fan.
  • Prim and Proper Bun: Her main hairstyle and she is quite the mature, ladylike woman.
  • Yamato Nadeshiko: With heavy emphasis on the will of iron. Her first appearance leaves it clear; not only she's a Lady of War able to stop katanas with a fan, but she took the pain of coming all the way from Osaka, make up a fake story so Kogoro won't suspect her, and hire him to look for someone else... so she can watch over him and his entourage, because she wants to see what kind of person he is after her only son got hurt in a case involving him.
