History Manga / KanojoNiNaruHi

* NoPeriodsPeriod: A rare example of this trope played straight in a GenderBender story.

* NoPeriodsPeriod: Another rare example of this trope played straight in a GenderBender story.

* AttractiveBentGender: A common result of emergence, which is one reason why there's a lot of prejudice against emerged people.

* GenderBender:
** FirstLawOfGenderBending: Emergence is implied to be always male to female. Reversions to male are possible with medical intervention but very rare, as it is implied to be a side effect of a "last step short of death" medical treatment. This is justified in-universe, in a complex way.
** SecondLawOfGenderBending: Played with: Mamiya seems to throw herself into femininity the same way she's attacked every other challenge, but Miyoshi soon realizes she's masking deeper psychological issues.
*** It isn't until years later while contemplating motherhood that Mamiya finally realizes emergence wouldn't have evolved in the first place if it weren't an effective reproduction strategy, which means some degree of acceptance is probably inevitable for most people. She expounds a bit further on this when counseling Sagara in the sequel (see below).
** ThirdLawOfGenderBending: Mamiya's so determined to tackle femininity head on she practically demands to be treated according to the third law during her reintroduction to the class. Miyoshi figures it's just another sign of her need to always master her emotions, though later chapters imply her close relationship with her baby sister may play into it as well, because the last thing she wants to do is give Miki the impression that there is something wrong with being a girl.
*** Lampshaded when Mamiya admits to Miyoshi that she doesn't always understand "girly" thinking despite her outward behavior and appearance.

* TransgenderFetishization: Two examples:

* TheUnfavorite: Kurokawa. Her parents tried to turn her into her deceased older sister after she emerged, even giving her the same name. She went along with it because she also believed her sister was a much better person and became a StepfordSmiler to hide her self-loathing.

!!Tropes found in Both Kanojo ni Naru Hi and Kanojo ni Naru Hi Another:

* AuthorAppeal: All four protagonists go on to become medical professionals: Miyoshi becomes a biomedical researcher specializing in Emergence, Mamiya becomes a psychological counselor for Emerged youth, Sagara becomes a nurse and Narumi a medical doctor.
* TeensAreMonsters: Inverted. The protagonist's classmates are, by and large, remarkably accepting and supportive with one or two exceptions. Even Shima is more of a tease than an antagonist. It's younger children and adults who tend to have and cause the most problems.

* SpoiledSweet: Miki could be used as the page image for this trope.

* DoggedNiceGuy: Miyoshi [[spoiler: dogged enough that he's willing to wait ''five years'' for Mamiya to wake from her second emergence.]]
* IfItsYouItsOkay: Mamiya takes advantage of this to help Miyoshi work through his gynephobia and later decides it's also the reason why Miyoshi is the only boy she's interested in. [[spoiler: It also inspires her to extend her second emergence until she's sure she'll remain a girl for Miyoshi's sake and ironically she emerges just after he finally admits that he'd still love her if she turned back into a boy.]]
* IKnowYouKnowIKnow: Miyoshi and Mamiya's perpetual rivalry began because Miyoshi wanted to distract Mamiya from the loss of his mother. It continued because Miyoshi also wanted to defeat Mamiya in ''something'' and never managed it. It gradually becomes apparent that they both knew what Miyoshi was up to all along and went along with it for their own reasons
* IllGirl: Mamiya's emergence stressed her body a lot more than she lets on, and her health is a lot more fragile than she would have people believe.

* VictoriousChildhoodFriend: Mamiya, eventually.

* IfItsYouItsOK: Mamiya takes advantage of this to help Miyoshi work through his gynephobia and later decides it's also the reason why Miyoshi is the only boy she's interested in. [[spoiler: It also inspires her to extend her second emergence until she's sure she'll remain a girl for Miyoshi's sake and ironically she emerges just after he finally admits that he'd still love her if she turned back into a boy.]]

* LastNameBasis: Miyoshi and Mamiya don't use each other's given names, Kyousuke and Nao. In fact, they don't even start using each other's given names until Miyoshi proposes, after they'd been dating for years and already have a sexual relationship

* BabiesEverAfter: the sequel reveals that Mamiya and Miyoshi eventually did get married and Mamiya, despite her fears, is happy as a young mother.

* DistantFinale: Ten years on, Sagara and Narumi have gone on to become a nurse and a medical resident respectively. [[spoiler: they're also busy planning their wedding]] while Kurokawa has finally broken with her parents over her refusal to get married.

* HideYourGays: You'd think a society where some children spontaneously change sex would be more open minded about gender and sexuality but Sagara has to choose between maintaining a male identity and pursuing a relationship with Narumi. It's not the sole motivation for his choice but it is the straw that breaks the camel's back. Sagara even hangs a lampshade on it, wishing he could walk hand in hand with Narumi and wondering why they can't.

* TheNickNamer: Miki. Kurokawa is "Ayaya" and Sagara is "Rinrin". Ironically she doesn't use her nickname for her oldest friend Narumi ("Yu Yu"} all that often, though she is on a first name basis with him.
* NoPeriodsPeriod: Another rare example of this trope played straight in a GenderBender story.
* NotSoDifferent: Sagara and Kurokawa on multiple levels. Both are emerged girls hiding important secrets.

* TheMindIsThePlaythingOfTheBody: Subverted: gender identity and presentation appear subject to social pressures as much as biology. There is no indication that either Sagara or Kurokawa's sexuality was affected by their transformations and their choices of gender identity and presentation appear to be due more to timing and social circumstances. Kurokawa was viciously bullied by boys after she emerged in elementary school and promptly became a ReplacementGoldfish for her beloved dead sister, whereas Sagara was already compensating for his girly appearance and has no one at home pressuring him one way or the other. Even so Sagara insists on remaining a boy primarily because he doesn't know how to live as a girl.
* TheyReallyDoLoveEachOther: Sagara's uncle Haruyuki initially seems aloof (Sagara certainly seems to think his uncle only took him in out of a sense of family obligation) but later events prove he genuinely cares and is actually paying close attention while not interfering. For example, he secretly bought Sagara a girl's uniform and a SchoolSwimsuit just in case Sagara elected to re-identify mid-year, but never tried to force them on him.
* MoodWhiplash: Kurokawa's revelations in Chapter 11 represent a significant mood shift, even in a comic that is played more for drama than comedy.
** The revelations about Sagara's parents in Chapter 14 certainly make the events of the earlier chapters much HarsherInHindsight. No wonder the poor guy is afraid to get close to anyone.
* SadisticChoice: Poor Sagara. A relationship with Narumi might force him to publicly re-identify as a girl, but a relationship with Kurokawa would also require him to be a girl even if she were willing to accept him pretending to be a boy in public. Either course requires surrendering his male identity. He even discusses this with Kurokawa, who recognises his dilemma.
* SecretKeeper: Narumi and Kurokawa both agree to keep Sagara's secret, each for their own reasons. Shima learns Sagara and Kurokawa's secrets, but has kept quiet so far. Miki could easily learn everyone's secrets if she compared notes with her sister. Sagara believes Miki is a SecretSecretKeeper because she is Nao's sister, though Miki herself has given no indication that she knows or cares about any of this,and Nao later assures Sagara that she's bound by professional ethics to keep his situation confidential.

* KnightTemplarBigSister: Nao. Played for laughs when she tells Narumi he isn't good enough for Miki only to switch instantly to isn't she good enough for you? when Narumi demurs. Turns up again in her BigDamnHeroes moment rescuing Sagara.

** SecondLawOFGenderBending: Played with: Mamiya seems to throw herself into femininity the same way she's attacked every other challenge, but Miyoshi soon realizes she's masking deeper psychological issues.

* {{Metamorphosis}}:the method of transformation, including cocoons.

* GiftOfTheMagiPlot: Chapter 13

* HideYourGays: You'd think a society where some children spontaneously change sex would be more open minded about gender and sexuality but Sagara to choose between maintaining a male identity and pursuing a relationship with Narumi. It's not the sole motivation for his choice but it is the straw that breaks the camel's back.

** Subverted later when school lets out for summer vacation and freed from the requirement to play SweetPollyOliver Sagara discovers there are also positive aspects to Different For Girls, mainly clothing that's much cooler in hot weather and attracts positive attention from Narumi while deflecting negative attention from homophobes and bullies put off by his girly looks.

* TheMindIsThePlaythingOfTheBody: Subverted: gender identity and presentation appear subject as much to social pressures as biology. There is no indication that either Sagara or Kurokawa's sexuality was affected by their transformations and their choices of gender identity and presentation appear to be due more to timing and social circumstances. Kurokawa was viciously bullied by boys after she emerged in elementary school and promptly became a ReplacementGoldfish for her beloved dead sister, whereas Sagara was already compensating for his girly appearance and has no one at home pressuring him one way or the other. Even so Sagara insists on remaining a boy primarily because he doesn't know how to live as a girl.

** Kurokawa plays it straight: being a ReplacementGoldfish for her older sister (and a LipstickLesbian who despises/likes boys) she's a classic GirlyGirl who tries to get Sagara into girly clothes using the pretext of exploring his options.

* TransgenderFetishization: Exploited, even: Emerged children and teens are especially at risk for being kidnapped by human traffickers. [[spoiler: Sagara's own mother tries to sell him to traffickers to clear her debts.]]

* TheUnfavorite: Kurokawa. Her parents tried to turn her into her deceased older sister after she emerged, even giving her the same name. She went along with it because she also believed her sister was a much better person and became a StepfordSmiler to hide her self-loathing.

** Ultimately played straight, though in a more nuanced fashion than most examples: Sagara still misses being a boy sometimes but is ultimately thankful for her change because it taught her important life lessons about love, friendship and caring for others. Rinichi Sagara was lonely, angry and bitter, Rin Sagara is loved and loves in return.

* MeaningfulName: Sagara's given name is eventually revealed to be "Rinichi", which means "Cold (or Severe)First-born Son".

* GenderBlenderName: Subverted in that the two explicitly gender bent characters have unambiguously gendered names: Aya (female) and Renichi (male).

** Ultimately played straight, though in a more nuanced fashion than most examples: Sagara still misses being a boy sometimes but is ultimately thankful for her change because of the lessons it taught her about caring for others and the personal growth that resulted from it. As Renichi Sagara was lonely, angry and embittered, Ren Sagara has friends who care for her and are cared for in return.

** Finally Narumi actually subverts this trope (at least at first) because he's afraid openly expressing his attraction to Sagara in female clothing would alienate Sagara. It takes him a while to understand that Sagara actually wants to be considered attractive (or at least normal) to him not matter how he is dressed.

** Ultimately played straight, though in a more nuanced fashion than most examples: Sagara still misses being a boy sometimes but is ultimately thankful for her change because of the personal growth that resulted from it

* SecondLawOfGenderBending: Averted. Sagara does not deny the physical change but is not willing to re-identify as a girl, though Nao counsels him that emergence's basis as a reproductive strategy means his sexual orientation is likely to swing towards men even as she acknowledges Kurokawa's lesbianism with "everyone is different."

** Mamiya shows off a skimpy bikini in the BeachEpisode, Justified InStory as an indication of Mamiya's desire to show that she's still the calm, cool, always-in-control person she was before despite her GenderBender and hidden illness, something she only admits indirectly several chapters and many years later when she confesses to Miyoshi that she refused to change or bathe with the other girls during that trip.

* BecomeTheMask: Kurokawa repeatedly demonstrates that she actually is the kind person she thinks she's only pretending to be.

* DistantFinale: ten years on, Sagara and Narumi have gone on to become a nurse and a medical resident respectively. [[spoiler: they're also busy planning their wedding]] while Kurokawa has finally broken with her parents over her refusal to get married.

* GenderBenderFriendship: inverted in that Sagara's GenderBender allows him to make friends with a male.

* LateArrivalSpoiler: the two manga are published concurrently, meaning readers of the second title already know that Mamiya and Miyoshi's sometimes rocky relationship will have an eventual happy ending.

* NoPeriodsPeriod: another rare example of this trope played straight in a GenderBender story.

* SecondLawOfGenderBending: Averted. Sagara does not deny the physical change but is not willing to re-identify as a girl, though Nao counsels him that emergence's basis as a reproductive strategy means his sexual orientation is likely to swing towards men even as she acknowleges Kurokawa's lesbianism with "everyone is different."

There is no indication that either Sagara or Kurokawa's sexuality was affected by their transformations and their choices of gender identity and presentation appear to be due more to timing and social circumstances.

* TransgenderFetishization: Acknowleged in-story: Emerged children and teens are especially at risk for being kidnapped by human traffickers. [[spoiler: Sagara's own mother tries to sell him to traffickers to clear her debts.]]

* TheyReallyDoLoveEachOther: Sagara's uncle Haruyuki initially seems aloof (Sagara certainly seems to think his uncle only took him in out of a sense of family obligation) but later events prove he genuinely cares and is actually paying close attention while not interfering. For example, he secretly bought Sagara girl's uniform and a girl's SchoolSwimsuit just in case Sagara elected to re-identify mid-year.

* JumpingTheGenderBender: The ultimate reason Sagara eventually comes out to his classmates: he simply cannot abide hiding his affection for Narumi any longer or the rumors his affection raises about Narumi's sexual orientation.

** Kurokawa plays it straight: being a ReplacementGoldfish for her older sister (and a LipstickLesbian who despises boys) she's a classic GirlyGirl and tries to get Sagara into girly clothes using the pretext of exploring his options.

** Despite his insistence on presenting as a boy Sagara gets hit with other female stereotypes, in particular ManOfSteelWomenOfKleenex and DamselInDistress.

** Initially subverted with Sagara, which actually causes more problems for him than playing it straight: the boys' uniforms don't fit right, cause him to overheat, and attract attention of the "it's hot, why are you still wearing your jacket?" variety that he'd prefer to avoid. Kurokawa's attempt to introduce him to feminine clothing caused his first major post-emergence freakout; His only concession on the clothing front is a high-compression sports bra for comfort and concealment. However, he does reconsider this attitude when he notices the way his girls' uniform affects Narumi, even though he tells himself it's because skirts are cooler in hot weather. Even then the trope is not played completely straight because Sagara is more interested in attracting Narumi than looking girly.
