Spoiler warning: Heiji and Kazuha’s relationship through manga File 1159, the outcome of their Volume 106 confession, and separate romantic developments in three films are revealed below.
Heiji Hattori and Kazuha Toyama are dating in the manga. The turning point is File 1133, The Dark Red Closing Night, the tenth chapter of Volume 106. Heiji’s feelings finally reach Kazuha at Naniwa Harukas. File 1159 later shows them announcing their relationship to their friends.
That is different from their earlier near-confessions, protective outbursts, and missed chances. The story eventually moves beyond showing that they care: they understand each other and acknowledge the relationship. A kiss is a separate question, and the scenes discussed here do not establish a completed kiss between the two of them.
Looking back from that outcome gives the earlier cases new warmth. Jealousy, a treasured charm, and a refusal to let go in danger all express feelings before the pair can make the words arrive at the right moment.
Where the relationship becomes official: Volume 106, File 1133
The confession at Naniwa Harukas changes their relationship from childhood friends with mutual but unspoken feelings to a couple. It is not simply another occasion when one person says something the other never hears.
File 1133 is the tenth chapter within Volume 106. The surrounding case occupies that volume’s sixth through tenth chapters. Reading the whole sequence matters because the investigation creates the pressure that derails Heiji’s plan and exposes what he actually wants.
The later confirmation in File 1159 is equally useful. They tell their friends they are dating, so the conclusion does not depend only on interpreting the emotional tone of the earlier confession. The relationship continues in the story after the moment of mutual understanding.
Why the confession works after the plan falls apart
The sunset plan competes with a murder investigation
Heiji wants to confess against the sunset visible from Naniwa Harukas. A visit to a play modeled on Kogoro and the others, followed by talk of a proposal backstage, sets the romantic plan in motion.
Then the outing becomes a serial murder investigation. The ominous stories around the production overlap with real deaths, and Heiji works with Conan to uncover the truth. A date-like plan cannot take priority over people in danger.
That is what makes the missed timing more than an arbitrary interruption. Heiji is pulled between responsibilities he genuinely takes seriously: solving the case and telling Kazuha something important. The carefully imagined moment passes while he is doing the work he cannot abandon.
The more perfect he wants the occasion to be, the more conditions there are for it to fail. He can rearrange the logic of a mystery, but cannot make a sunset wait for him.
Kazuha hears the unguarded admission
Believing he has missed another chance, Heiji lets out his frustration and admits that he only wants to tell Kazuha he loves her. It is no longer a polished line prepared for an audience. It is the wish underneath all the staging.
Kazuha hears him. The words do not disappear into a private mutter; her response makes them part of a conversation between the two of them. Heiji does not retreat into another ambiguous excuse, and their feelings finally become mutual knowledge.
The scene suggests that his elaborate plans were never the real goal. Perhaps he wanted to make the occasion special for her, as well as compete with Shinichi’s romantic milestone. What actually reaches Kazuha is Heiji without the performance.
That is why the ending suits them. After a long wait, they do not abruptly become different, more elegant people. The clumsy honesty belongs to the same pair who have repeatedly missed their chance to connect, and this time it is enough.
Files 1157-1159: what happens after they start dating?
The planetarium distance is part of a surprise
The Tokyo planetarium case in Files 1157-1159 initially shows Heiji and Kazuha keeping an odd distance from each other. File 1159 explains why: they wanted to surprise their friends with the news that they were dating, and were deliberately avoiding giving it away too soon.
They have not fallen out, and the Volume 106 confession has not been canceled. Their behavior is an attempt to manage the announcement. Ran and the others already know, which leaves the would-be surprise without quite the reaction the pair expected.
The reversal is lovely. Earlier, the necessary information could not reach the other half of the couple. Now, it has reached their friends before the couple is ready to reveal it. The familiar mismatch remains, but Heiji and Kazuha are finally on the same side of it.
They have become a couple without becoming immune to overthinking. Their shared attempt to surprise everyone is gentler comedy than the old missed confessions, because it rests on a relationship they have already established.
The manga File numbers distinguish the successful confession in File 1133 from the later announcement in File 1159.
Momiji’s new way of referring to Kazuha does not settle her feelings
File 1159 also changes the way Momiji Ooka thinks of Kazuha: she uses Kazuha’s name instead of her earlier leaf-based nickname. The shift may suggest that she is recognizing her rival’s position differently.
It does not prove that Momiji has stopped loving Heiji or abandoned every hope of a relationship. Learning that two people are dating and resolving one’s own feelings about that fact are separate developments.
The couple’s happiness does not require treating Momiji’s emotions as a joke with no remainder. A small change in language can leave room for that disappointment without undermining the confirmed relationship between Heiji and Kazuha.
The anime adaptation: the Naniwa Harukas finale
The Volume 106 story is adapted across Japanese episodes 1214-1216. The theater investigation interrupts Heiji’s plan to confess at Naniwa Harukas, and the final part brings both the case and the confession to their conclusion.
The manga’s progression remains distinct: File 1133 contains the successful confession, while File 1159 confirms the couple’s later announcement. The announcement is a later manga event, not part of this three-episode anime case.
The investigation giving way to Heiji’s confession is part of the adaptation’s appeal. The scene’s force comes from the change in the conversation, not simply from reaching another number on an episode list.
Before the confession: affection shown through actions
Volume 19: Kazuha mistakes Kudo for a romantic rival
Kazuha’s debut is in Volume 19, adapted as Episodes 124-125 (Japanese episode 118), The Naniwa Serial Murder Case (1 Hour Special). Heiji’s frequent talk about Kudo has led her to imagine a woman occupying his attention, and she initially treats Ran as that supposed rival.
Heiji is thinking about a detective he wants to compete with. Kazuha hears the repeated attention to someone in Tokyo and reaches a very different explanation. Her suspicion makes the feeling visible before she gives it a straightforward name.
The case also introduces the significance of the charm and the childhood handcuff chain. An accidental physical link between them has become something Kazuha keeps. Their arguments may be loud, but the little object quietly preserves a history that belongs to the two of them.
Volumes 21-22: matching clothes mean different things to them
Episodes 151-152 (Japanese episodes 141-142), The Night Before the Wedding Locked Room Case (Part 1) and The Night Before the Wedding Locked Room Case (Part 2), adapt the relevant case across Volumes 21-22.
Kazuha notices when Ran and Heiji have matching clothes. When she herself matches Heiji, his cheerful response is to compare them to siblings. He does not mean to hurt her, but it is not the recognition she wanted.
The distinction is small and revealing. To Kazuha, sharing the look can carry romantic meaning. Heiji treats it as the comfortable closeness they have always had. They are near enough to seem like family, yet that familiarity makes the new meaning harder to communicate.
Volume 25: Kazuha’s danger breaks through Heiji’s composure
The Tottori case is adapted as Episodes 177-179 (Japanese episodes 166-168), from Tottori Spider Mansion Demon (The Case) to Tottori Spider Mansion Demon (The Resolution).
Kazuha disappears and is found in a storehouse, turning the investigation into a threat to someone close to Heiji. His urgency makes a sharp contrast with his usual banter. Being skilled at solving crimes does not protect him from fear about what may have happened to her.
The scene need not be labeled a formal romantic realization to matter. It shows which danger strips away his easy confidence, revealing the importance of the person he normally takes for granted beside him.
Volume 28: neither will let the other die
The mermaid case is adapted as Episodes 241-243 (Japanese episodes 222-224), from And Then There Were No Mermaids (The Case) to And Then There Were No Mermaids (The Resolution). Its cliff sequence gives the relationship stakes that go far beyond a confession.
Heiji holds Kazuha while he is also in danger of falling. She tries to force him to release her, believing that saving her may kill him too. He refuses. The frighteningly rough words he uses to stop her moving express a determination to keep her alive, not a wish to harm her.
Her attempt to save him only strengthens his resolve. Both are trying to preserve the other’s life, and those intentions clash in a situation where neither can feel safe. The scene is difficult to watch precisely because the protection goes in both directions.
They are not dating yet. Their actions nevertheless reveal a bond strong enough to risk their lives for, making the later difficulty of saying something simple even more poignant.
Volumes 31-32: Kazuha wants to see Heiji in his element
Episodes 282-285 (Japanese episode 263), The Osaka Double Mystery – The Naniwa Swordsman and Toyotomi’s Castle (2 Hour Special), bring out a quieter side of Kazuha’s affection.
She wants to see the bright expression Heiji has when he solves a case. That is more specific than liking him because they grew up together. She notices the pleasure he takes in doing something well and wants to be there for it.
There is a productive contradiction in her attitude: the detective work that frustrates her by stealing his attention is also part of what she loves watching. Her affection includes respect for the person he is when he becomes absorbed in the truth.
Volume 38: the words he might leave behind
In Episodes 348-349 (Japanese episodes 323-324), Heiji Hattori’s Desperate Situation! (Part 1) and Heiji Hattori’s Desperate Situation! (Part 2), Heiji and Kazuha are confined and forced to solve a code under threat of death.
Heiji speaks of leaving a final word for the girl behind him. The possibility that these could be his last words changes their emotional weight: even with no clear way out, his attention goes to Kazuha.
But wanting to leave a final message is not itself a successful confession. The case does not establish that they begin dating. Its importance lies in how the crisis exposes a feeling that their ordinary conversations still cannot settle.
Volume 47: Heiji is jealous too
Episodes 440-442 (Japanese episodes 406-408), from Conan and Heiji’s Deduction Magic (The Trick) to Conan and Heiji’s Deduction Magic (The Resolution), reverse the familiar impression that Kazuha is always the jealous one.
When Kazuha admires another man, Heiji becomes irritated. He tries to explain that reaction through the idea that he regards her as a subordinate, rather than acknowledging a romantic attachment.
The gap between the explanation and the behavior is the point. He may want her attention on him without being ready to name why it matters. His deductions about a case are quick; the explanations he gives for his own feelings can take a much longer route.
Volume 66: the photo inside the charm
The eighth through tenth chapters of Volume 66 are adapted as Episodes 624-625 (Japanese episodes 573-574), The Whereabouts of the Embarrassing Charm (Part 1) and The Whereabouts of the Embarrassing Charm (Part 2).
Kazuha urgently wants the charm back because she does not want Heiji to see the photograph of him inside it. What she needs to conceal is the evidence of how much she values him.
The charm has accumulated different meanings: protection, a shared childhood memory, and now a private place for her affection. While Heiji follows the case, Kazuha is worrying about what the object might reveal. They are in the same situation but anxious about entirely different discoveries.
Attempts to confess: why the words keep missing their mark
Volumes 74-75: Kazuha makes her own attempt
Episodes 704-707 (Japanese episodes 652-655), from The Design of Poison and Mirage (EYE) to The Design of Poison and Mirage (Illusion), include Kazuha’s effort to declare her feelings.
She is not merely waiting for Heiji to take the initiative. After struggling to get the words out, she says she loves him. He does not hear the confession, so it does not become a mutual acknowledgment or the start of dating.
The comic failure should not erase the courage of her attempt. Knowing the eventual outcome makes it easier to see that both of them tried to change the relationship, even when the words failed to reach the person who mattered.
Volume 83: the slip at Ebisubashi
In Episodes 816-817 (Japanese episodes 763-764), Conan and Heiji, Code of Love (Part 1) and Conan and Heiji, Code of Love (Part 2), Heiji believes Kazuha is in danger and refers to her possessively as he confronts the men involved.
Kazuha notices the possessive part and challenges it. That reaction makes the exchange especially enjoyable: the feeling escapes him, and she refuses to pretend she did not hear it.
The slip is a strong sign of affection, but it does not make them a couple. It is different from the later scene in which they acknowledge their feelings to each other. Heiji can sound most honest when he has no time to prepare the perfect words.
Volumes 90-91: a spectacular setting is not enough
Episodes 927-929 (Japanese episodes 872-874), from Conan and Heiji’s Nue Legend (Squealing) to Conan and Heiji’s Nue Legend (Resolution), take the pair to a village on a buried-treasure assignment.
Heiji also has a confession in mind. His wish for a special view appears to combine wanting to delight Kazuha with wanting to measure up to Shinichi. The ominous legend and the case interfere, and the hoped-for occasion does not work out.
The more seriously he takes the confession, the more requirements he seems to attach to it. That makes the effort touching as well as frustrating: he cares enough to plan, but the plan becomes another obstacle to simply telling her.
Volumes 93-94: win the tournament, then confess
In Episodes 971-972 (Japanese episodes 916-917), The Kendo Tournament of Love and Mystery (Part 1) and The Kendo Tournament of Love and Mystery (Part 2), Heiji ties his confession to winning the tournament, with Soshi Okita as a major rival.
A murder prevents him from concentrating only on the match. He wants to solve the case, prove himself in kendo, and tell Kazuha how he feels. Each admirable goal becomes entangled with the others.
He does not actually need to win something before he is allowed to love her. Yet wanting her to see him at his best makes the extra condition understandable. His competitive pride is part of the appeal and part of the problem.
Volumes 94-95: Shinichi and Ran move forward
Episodes 982-985 (Japanese episodes 927-928), The Scarlet School Trip (Bright Red Arc) (1 Hour Special) and The Scarlet School Trip (Red Love Arc) (1 Hour Special), advance Shinichi and Ran’s relationship.
Their progress prompts Heiji to think again about his own. Shinichi is his rival in deduction and a trusted friend, so it is easy to understand why romantic progress would also stir his competitive instincts.
But romance is not an investigation won by arriving at the answer first. The two couples have different histories. Heiji’s comparison reveals his impatience, while the effect of his friends’ happiness helps push his next attempts forward.
Volume 96: the almost-kiss involves a disguised Kid
Episodes 1040-1041 (Japanese episodes 983-984), Kid vs. Komei: The Targeted Lips (Part 1) and Kid vs. Komei: The Targeted Lips (Part 2), contain an important distinction: the person Heiji nearly kisses is Kaito Kid disguised as Kazuha.
The person in front of Heiji is not Kazuha, and no kiss is completed. It cannot be counted as Heiji and Kazuha’s first kiss merely because the disguise looks like her.
The comedy comes from the normally elusive thief getting caught in Heiji’s romantic momentum. The incident also leaves a grievance between the characters, so the failed romantic advance has consequences beyond a single joke.
Volume 98: the heart-shaped opportunity
Episodes 1081-1082 (Japanese episodes 1024-1025), Momiji Ooka’s Challenge (Part 1) and Momiji Ooka’s Challenge (Part 2), give Heiji a heart-themed opportunity while the characters pursue Momiji’s code.
He announces his intention to convey his heart to Kazuha and tries to turn the occasion into a special anniversary. By now the problem is hardly whether he has feelings. It is how and when to deliver them.
The attempt still does not produce a successful confession. His enthusiasm makes the failure more frustrating, but also shows how much he wants their beginning to matter. It is difficult to dismiss the effort as merely foolish when the desire behind it is so sincere.
Volume 100: even matchmaking luck cannot replace a conversation
Episodes 1143-1144 (Japanese episodes 1085-1086), The Inauspicious Matchmaking (Part 1) and The Inauspicious Matchmaking (Part 2), take place at Haido Shrine, associated with matchmaking.
Heiji as well as Kazuha is interested in romantic luck. Yet he tries to conceal his identity from her, placing another barrier between them even when they have come to the same place with related hopes.
The contradiction is endearing: he wants help moving the relationship forward while remaining embarrassed about revealing that wish. Prayers and charms can express how much a bond matters, but they cannot do the final work of speaking for the couple.
Volume 105: Ran helps, but the weather and a case intervene
Files 1116-1118 are adapted as Episodes 1236-1237 (Japanese episodes 1178-1179), The Crimson Skeleton of Mt. Washio (Part 1) and The Crimson Skeleton of Mt. Washio (Part 2).
Ran tries to support the romance by bringing Heiji and Kazuha to a beautiful viewpoint. Rain sends the party to shelter at a temple, and Kogoro’s disappearance and the case disrupt the plan.
Even an encouraging friend cannot arrange away every obstacle. The failed attempt does not begin their relationship, but it sharpens the contrast with Naniwa Harukas: after so much effort to secure a view and an opportunity, the decisive moment will be an unadorned statement of feeling.
The three films are separate romantic stories
The films give the pair memorable romantic moments, but their movie-only events must not be substituted for the manga’s dating milestone.
Crossroad in the Ancient Capital: the first love was Kazuha
In the movie-only Crossroad in the Ancient Capital, Heiji’s childhood first love turns out to be Kazuha. The girl in a distant memory and the familiar person beside him are one and the same.
Kazuha worries about the remembered girl without realizing that she herself is the answer. The revelation gently rearranges the meaning of their past: she has not suddenly become special, but has occupied more than one important place in his life all along.
This is not a story in which they begin dating. It offers a different pleasure: the discovery of a bond that existed before either understood its full shape.
The Crimson Love Letter: Kazuha acts on her own feelings
The movie-only The Crimson Love Letter introduces the rivalry through Momiji’s claim that Heiji will be her husband. That claim expresses her expectation; it does not establish a formal engagement agreed by Heiji.
Kazuha does more than react with jealousy. With help from Heiji’s mother, Shizuka, she trains for competitive karuta and faces Momiji through a contest that requires effort. She is prepared to attempt something unfamiliar because the relationship matters to her.
The romance works because protection is not the only direction of action. Heiji may rescue her in danger, but Kazuha is also doing something for herself. Her feelings make her move, rather than simply wait for an outcome.
The Million-dollar Pentagram: he says it, but she cannot hear
In the movie-only The Million-dollar Pentagram, Heiji confesses against Hakodate’s night view. Kazuha’s hearing has temporarily been affected by a stun grenade, and the declaration does not reach her.
That is different from Heiji failing to find the courage to speak. He does say what he feels. The painful mismatch is that the intended listener cannot receive it, so the scene does not establish a dating relationship.
The view, the private moment, and the decision to speak are all present; communication is still missing. It makes the manga’s later published resolution feel different: a confession becomes a shared event only when the other person can respond to it.
Have Heiji and Kazuha kissed?
Dating and a completed kiss are separate milestones. None of the scenes discussed here establishes an on-page or on-screen completed kiss between Heiji and Kazuha themselves.
Volume 96 gives an attempted kiss with Kid in disguise. Volume 106 gives the confession that reaches Kazuha. The Million-dollar Pentagram gives a movie-only declaration she does not hear. Treating those as the same kind of romantic progress would erase the distinction that gives each scene its meaning.
Their mutual feelings and File 1159 announcement are already substantial developments. There is no need to assume a further event merely because they are now a couple.
The reward for following them is also in the smaller changes: how they speak, what they try to hide, and the surprise that their friends no longer need. Looking back at the charm, Kazuha’s admiration, and the hand Heiji would not release makes the long path feel like more than a list of failed attempts. The feelings were there; now the two people involved finally know it together.
