3	''Kanojo ni Naru Hi'' ("The Day He Became A Girl") is a {{shoujo\|Demographic}} manga series by Ogura Akane. It was serialized in ''[[Magazine/LaLa Ane LaLa]]'' from 2013 to 2017 and compiled into four volumes.
4
5	Miyoshi is always competing and losing against his childhood friend, Mamiya, who is good at everything and completely unable to resist a challenge. But their more-or-less friendly rivalry is broken when Mamiya is hospitalized and emerges as a girl. In Mihoshi and Mamiya's world, "emergence" is a natural process that maintains the ratio between the sexes. Whenever there aren't enough women some boys [[{{Metamorphosis}} transform into girls]]. While emergence isn't exactly uncommon (tens to hundreds of cases every year) it usually happens in young children who are rapidly developing anyway, otherwise the resulting stresses on the body are very dangerous to teenagers and invariably fatal for adults.
6
7	Refusing to mope Mamiya, breezily returns to school unequivocally and seemingly unabashedly female, determined to seize life as a girl and equally determined to help Miyoshi overcome his severe gynophobia. But Miyoshi soon comes to suspect that there's actually a great deal of turmoil going on beneath Mamiya's seemingly happy-go-lucky surface.
8
9	In the sequel ''Kanojo ni Naru Hi Another'' Sagara, a short, slight, and girly-looking boy who has cultivated a tough-guy image to compensate emerges as a girl halfway through his second year of middle school and is forced to confront a stark choice between maintaining his identity as a boy and forging a new identity as a girl, a choice only complicated by a new attraction to Narumi, his rival for the affections of the cool, collected class representative Kurokawa.

15	[[folder:Common tropes]]
16	* 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.
17	* 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.
18	* GenderBender: In this series, a small number of males rapidly become female, seemingly at complete random.
19	* 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.

21
22	[[folder:Tropes found in ''Kanojo ni Naru Hi'']]
23	* AllergicToLove: Mamiya has severe intimacy issues stemming from the breakup of her parent's marriage.
24	* AloofBigBrother: Subverted. Mamiya's love for her little half-sister Miki was alwasy unequivocal and freely given even before she changed into a girl.
25	* AlwaysSecondBest: Miyoshi is constantly challenging and losing to Mamiya, be it soccer, Aikido, or academics...until she emerges. She still beats him in academics
26	* BestHerToBedHer: Played with and gender-flipped: Mamiya is so competitive she likes to keep Miyoshi "on the back foot" in order to maintain control of their relationship while Miyoshi gets the victory he's always desired every time he flusters her, so their love quickly evolves into a gentle competition to see who can make the other blush the most.
27	* ChekhovsSkill: Miyoshi's family runs a dojo and both Miyoshi and Mamiya earned black belts, though the payoff doesn't come until their BigDamnHeroes moment in the sequel.
28	* ChildhoodFriendRomance: Victorious Mamiya, eventually.
29	* CompensatingForSomething: Mamiya's drive to excel at everything turns out to have some very ugly roots.
30	* CoolBigSis: Miki Mamiya practically worships her big sister Nao.
31	* DoggedNiceGuy: Miyoshi [[spoiler: dogged enough that he's willing to wait ''five years'' for Mamiya to wake from her second emergence]].
32	* FreudianExcuse: Mamiya's deep psychological need to excel at everything--even femininity--comes from her sense of ParentalAbandonment, which her emergence only complicates by making her resemble the mother who abandoned her.
33	* GiftOfTheMagiPlot: Chapter 13.
34	* 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.]]
35	* 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
36	* 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.
37	* {{Metamorphosis}}: The method of transformation, including cocoons.
38	* MissingMom: Mamiya has severe abandonment issues because her mother abandoned Mamiya and her father only to turn right around and start a new family with another man.
39	* TheOnlyOneAllowedToDefeatYou: The basis of Miyoshi and Mamiya's relationship, which later morphs into a Gender-flipped BestHerToBedHer when Mamiya decides to engage on the romantic front.
40	* 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.\
41	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).
42	* ShamelessFanserviceGirl: Mamiya in her first bikini. Miyoshi figures she's overcompensating, which Mamiya finally admits years later on their honeymoon.
43	* StarCrossedLovers: Mamiya and Miyoshi, especially since they keep unintentionally friendzoning each other.
44	* StepfordSmiler: Mamiya keeps up a solid front and only breaks down when it becomes apparent she can no longer compete physically with Miyoshi.
45	* StrongFamilyResemblance: Post-emergence Mamiya looks remarkably like the MissingMom who abandoned her, causing her much angst.
46	* 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.

50	* AbusiveParents: There's a reason Sagara lives with his uncle. It isn't pretty. [[spoiler: His mother later tries to sell him into the sex trade or for medical experiments, it's not clear which and she doesn't particularly care.]] He claims (falsely, it turns out) that his parents are dead.
51	* AccidentalTruth: Narumi blurting out "I didn't expect you to be this cute" marks the first turning point in their relationship.
52	* AdultsAreUseless: subverted. All of Sagara's teachers and caseworkers are fully in the loop and appear genuinely interested in his welfare. They identify opportunities for him to re-identify as a girl but they respect his choices. For example they arrange for him to take the mandatory swim test on Sunday, so he won't be forced to reveal his secret to anyone who doesn't know it already.
53	* AlternateCharacterReading: Inverted, Aya and her deceased elder sister share the same name but it's written with different Kanji.
54	* ArmorPiercingQuestion: "Can I see you as a girl?"
55	* AwLookTheyReallyDoLoveEachOther: 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.
56	* BabiesEverAfter: The sequel reveals that Mamiya and Miyoshi eventually did get married and Mamiya, despite her fears, is happy as a young mother.
57	* BecauseYouWereNiceToMe: A recursive example: Sagara is grateful for Kurokawa's kindness even before he emerges, unaware that she's repaying him for the kindness he showed her in grade school.
58	* BecomingTheMask: Kurokawa repeatedly demonstrates that she actually is the kind person she thinks she's only pretending to be.
59	* BigDamnHeroes:
60	** Nao and Kyousuke confronting the human traffickers after Sagara
61	** Narumi going out of his way to take care of Sagara when he falls ill counts as well.
62	* BisexualLoveTriangle: Sagara thought he and Narumi were straight-up rivals for Kurokawa's affections only to learn he's actually the apex of their love triangle thanks to the revelations prompted by his emergence. Narumi thinks he's jealous of Sagara's attentions to Kurokawa, when he's actually jealous of Kurokawa's attentions to Sagara. Unusually for a gender-bending triangle such as this, Sagara falling for Narumi makes him feel obligated to identify and present as female, but [[DoubleStandard no one questions the social acceptability of dating Kurokawa as a girl]]--which Kurokawa ''herself'' pushes for Sagara to do, because she'd rather date someone who's completely female.
63	* ClassRepresentative: Kurokawa, though she is an atypical example.
64	* CoolBigSis: Nao and Miki are still extremely close and she spoils Miki unmercifully. Miki's friends even comment on Nao's "Big Sister Complex".
65	* ConvenientlyAnOrphan: Sagara's lack of parental guidance is certainly convenient for the author. It means he has no one at home influencing his gender choices.
66	** Sagara's insistence that he is an orphan (even to himself) is psychologically convenient because it's less painful than the truth: his father is a deadbeat and his mother lost custody for abusing him.
67	* DifferentForGirls: Sagara cites avoiding this trope as his primary reason for wanting to continue living as boy, But even though Sagara is hiding his GenderBender he still has to deal with the physical changes, mainly (aside from the obvious) decreased strength and increased flexibility.
68	** 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. Dressing
69	* 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.
70	* FantasticRacism: It turns out there can be a good deal of prejudice against the emerged, and they're prime targets for human traffickers.
71	* FriendlessBackground: Subverted: Sagara tries to keep his classmates at a distance, but they mobilize to help him anyway.
72	* TheGadfly: Shima needles Sagara and Kurokawa relentlessly until he discovers their secrets... then appears so taken aback by what he learns, especially from Kurokawa, that he doesn't do anything with the information.
73	** Narumi needled Sagara into trying on girl's clothing in a classic example of reverse psychology--only to be unprepared for his own reaction to the results.
74	* GenderBenderFriendship: Inverted in that Sagara's GenderBender allows him to make friends with a male.
75	* GenderBlenderName: Subverted in that the two explicitly gender bent characters have unambiguously gendered names: Aya (female) and Rinichi (male).
76	* HeroOfAnotherStory: Mamiya's little sister Miki is a classmate, and Narumi's lifelong friend. Mamiya herself is one of Sagara's Ministry of Health caseworkers.
77	* HideYourLesbians: 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.
78	* ItsAllAboutMe: Sagara's mother's attitude in a nutshell. [[spoiler: Not only does she blithely try to sell him to clear her debts, she actually expects him to go along with it for the sake of his dear old mom, and actually has the gall to ask him if he was going to abandon her when her plans fall through.]]
79	* IfItsYouItsOK: It's not clear if Kurokawa would be willing to accept a lover who is only physically female. Though she does appear willing to give it a try, she also tries to get Sagara to wear girl's clothing. The jury's still out on Narumi with respect to Sagara, but Sagara appears willing to apply this to Narumi.
80	* IncompatibleOrientation: After Sagara emerges Kurokawa reveals that neither he nor Narumi ever really had a chance wooing her because she's a lesbian. (Note: There is an omake at the end of the series that addresses: "What if Sagara and Narumi both emerged". According to the author: the outcome would have been that Sagara and Narumi would have fought and argued over Kurokawa during the whole school years, and that at some point Kurokawa got so tired with their overbearing advances that she eventuslly started dating a boy to stop them from pursuing her. The consequences is that both of the girls would have descended into rejection bonding over drinks. It is unknown if the girls pursued of lesbian relationship after Kurokawa opted out of their toxic rivalry.)
81	* IWantMyBelovedToBeHappy: Kurokawa breaks up with Sagara when it becomes obvious (to her, he's still clueless) that Sagara is actually smitten with Narumi.
82	* KnightTemplarBigBrother: 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.
83	* JumpingTheGenderBarrier:
84	** 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.
85	** Discussed when 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."
86	* LadyLooksLikeADude: Sagara sucessfully hides his GenderBender because he's always been small and has no figure to speak of.
87	* LastNameBasis: Sagara, Narumi, and Kurokawa are all on a family name basis, Sagara and Narumi because they are rivals and Kurokawa because that's typical of Japanese gender relations. Given names would imply a more intimate relationship than any of them are willing to admit.
88	* 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.
89	* MeaningfulName: Sagara's given name is eventually revealed to be "Rinichi", which combines the kanji for "Cold" (or "Severe") and "One" (or "Primary"). While the BlindIdiotTranslation ("Cold First") doesn't make a lot of sense in English the more idiomatic translation "Stoic First-born" pretty much describes him to a T.
90	* 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.
91	* MoodWhiplash: Kurokawa's revelations in Chapter 11 represent a significant mood shift, even in a comic that is played more for drama than comedy.
92	** 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.
93	* MortonsFork: 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.
94	* 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.
95	* ObliviousToLove: Sagara either can't understand or is unwilling to admit why Narumi flusters him.
96	** Narumi doesn't understand why he thinks of Sagara at random moments.
97	* OldFriendNewGender: Sagara is very surprised to discover that Kurokawa was a boy he knew back in elementary school.
98	* OneHeadTaller: Narumi and Sagara, underscoring their OTP status
99	* ParentalAbandonment: Sagara insists his parents are dead; the truth isn't much prettier. [[spoiler: Sagara's father is a ne'er do well gambler with a habit of running out on his debts, his mother is TheResenter, who hates him for being an ever-present reminder of his loser father... and for looking better than she does.]]
100	* PoorCommunicationKills: Sagara finally wears a girls' uniform (strictly for disguise purposes, he still isn't sure about re-identifying, but has to pretend long enough to take the swim test) then gets very upset when it appears not to bother Narumi. Turns out Narumi is actually gobsmacked by Sagara's cuteness but fears admitting that would alienate Sagara. They do work it out eventually
101	* RememberTheNewGuy: Miki doesn't show up as a named character until Chapter 3, though she is depicted as an extra in Chapter One (She's the girl who accidentally squirts Sagara with the hose.)
102	* ReplacementGoldfish: Kurokawa is a voluntary replacement goldfish for her older sister (also named Aya), whom her parents prefered. She goes along with it because she loved her sister, is convinced that her sister was truly a better person, and feels tremendous guilt for jealously wishing her sister ill before she died.
103	* RescueRomance: Kurokawa is thrilled to discover that Sagara is now female because he saved her from bullies back in elementary school. Sagara feels a bit guilty because he didn't particularly want to rescue her, he just liked to fight.
104	* SecondLawOfGenderBending: Sagara starts off accepting the physical change but unwilling to re-identify as a girl. 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 kicked her out of a self-destructive rut and 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.
105	* 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.
106	* SheIsNotMyGirlfriend: Narumi's instinctive denial to his Mother, while technically true and intended primarily to keep his mom out of his business, opens a huge emotional minefield for Sagara until Narumi points out that he's waiting for Sagara's permission to treat him as a girl.
107	* SilkHidingSteel: Kurokawa: GirlyGirl on the outside, implacable as a glacier on the inside.
108	* StepfordSmiler: Kurokawa hides a seething mass of grief, guilt and self-loathing under her cool, quiet and kind exterior and her secret joy that Sagara has emerged is just one more thing to feel guilty about. She even tells Shima "The real me is ugly" after he learns her secret.
109	* TheStoic: Sagara, already isolated by his tough-guy image, goes to extra lengths to keep his secret and protect his beleaguered manhood
110	* ThereAreNoTherapists: subverted. The protagonist of ''Kanojo ni Naru Hi'' is the protagonist's caseworker in ''Kanojo ni Naru Hi Another'' and therapy is readily available
111	* ThirdLawOfGenderBending: Played with.
112	** Kurokawa plays it straight: being a ReplacementGoldfish for her older sister (and a LipstickLesbian uninterested in boys) she's a classic GirlyGirl who tries to get Sagara into girly clothes using the pretext of exploring his options.
113	** 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 ilthe 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 and dresses 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.
114	** Despite his insistence on presenting as a boy Sagara gets hit with other female stereotypes, in particular MenAreStrongWomenArePretty and DamselInDistress.
115	** 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, no matter how he is dressed.
116	* 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.
