History Manga / NyotaiKa

* BleachedUnderpants: It should be to absolutely no one's surprise that many of the mangaka's other GenderBender works are less ecchi and more outright {{hentai}}.

* {{Bishounen}}: Averted by Makoto, who looks unambiguously male (until he suddenly isn't). [[spoiler: Iwanami, on the other hand, plays this straight when she turns into a guy.]]
** Kei looks pretty much exactly the same as Makoto as a girl when he's a guy.

''Nyotai-ka'' is a comedy {{ecchi}} manga about a junior {{Salaryman}} named Manaka Makoto, who, frustrated by his lack of success in his own love life, decides it would be [[ForTheLulz amusing]] to troll an online dating site as a {{GIRL}} in order to spread the frustration. This winds up epically backfiring when a goddess decides to intervene and make him [[GenderBender an actual woman]].

* ChristmasCake: Makoto learns that her parents are no exception to the CosmicRetcon when her mother warns her of this trope.

* BeCarefulWhatYouWishFor: Why Makoto became a girl. He's tired of lavishing his money and attention on women who don't reciprocate, so he wishes he could be a girl so someone would pay attention to him for a change.
** On a deeper level, Girl-Makoto does get the attention (and gifts) Boy-Makoto wanted but at the cost of living with the constant burden of men who expect sex in return and aren't particularly willing to take no for an answer. And she quickly learns that just being a young women means getting constantly hit on by pretty much every male she encounters.

* BuxomIsBetter: Makoto's female form is, by Iwanami's estimations, either a D or E cup.

* FailedASpotCheck: Iwanami completely fails to notice Makoto has somehow transformed from a tall skinny man to a petite buxom woman. However, there seems to be some sort of WeirdnessCensor effect, because none of their fellow employees seem to notice either. Makoto's change is eventually raised to the level of a CosmicRetcon.

* HornyDevil: Nanashi and deimu turn Kei into one while possessing him.

HilarityEnsues.

* {{Meganekko}}: Iwanami.

* ClosetKey: Makoto's GenderBender causes an awakening in Iwanami, though it's less generic lesbianism than an odd combination of SingleTargetSexuality and IfItsYouItsOkay.

* BleachedUnderpants: It should be to absolutely no one's surprise that many of the mangaka's other GendeBender works are less ecchi and more outright {{hentai}}.
