History Manga / KanojoNiNaruHi

* StepfordSmiler: Kurokawa hides a seething mass of guilt under her calm, cool, 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 discovers her secret.

* CoolBigSis: Nao and Miki are still extremely close. Miki's friends even comment on Nao's "Big Sister Complex"

* StepfordSmiler: Kurokawa hides a seething mass of guilt under her calm, cool, kind exterior, and her secret joy that Sagara has emerged is just one more thing to feel guilty about.

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 during his third 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.

** FirstLawOfGenderBending: Reversions to male are not unheard of but very rare..

* SadisticChoice: Poor Sagara. A relationship with Narumi would force him to publicly re-identify as a girl, but a relationship with Kurokawa would also require him to admit to being a girl in private even if he remained a boy in public. Either course requires surrendering some aspect of his identity.

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 turns into a girl. In Mihoshi and Mamiya's world, the ratio between the sexes is maintained by a process called "emergence": when 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 only happens in young children whose bodies are rapidly developing anyway, otherwise the resulting stresses on the body are very dangerous to teenagers and invariably fatal for adults.

Manga by Ogura Akane

* IfItsYouItsOK: Mamiya takes advantage of this to help Miyoshi work through his gynephobia, but later decides it's also the reason why Miyoshi is the only boy she's interested in.

* TheMindIsThePlaythingOfTheBody: subverted: gender identity and presentation appear subject more to social pressures than biology. Their 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 emerged in elementary school and may not have been able to hide it even if she wanted to, presuming her parents would have allowed it, whereas Sagara was already compensating for his girly appearance.

* BecauseYouWereNiceToMe: A recursive example: Sagara is grateful for Kurokawa's kindness, unaware that she's repaying him for his kindness in the past.

* ThirdLawOfGenderBending: subverted, which actually causes more problems for Sagara than playing it straight: the boy's uniform fits him poorly now and he can't remove his jacket or his sweatsuit top during gym.

* SadisticChoice: Poor Sagara. A relatioship with apparently straight Narumi will probably force him to publically re-identify as a girl, but a relationship with Kurokawa would probably also require him to admit to being a girl in private even if he remained a boy in public. Either course requires surrendering some aspect of his identity
