History Manga / LoveGeneXX

* [[PuttingOnTheReich Putting on the Thermidor]]: The costumes in this manga follow a distinctly Versailles fashion (despite being set in the future)--partly as a nod to a certain [[Manga/RoseOfVersailles manga about another crossdressing swordswoman]], partly foreshadowing TheReveal that [[spoiler:there is a social revolution in the brewing]].

* ThoseTwoGirls: Renge Ooyama and Maki Abe serve as Erika "bodyguards" and spies--that's pretty much their entire role.

* IdleRich: This is how Aoi views the Etoiles, although towards the end of the manga, it becomes apparent that [[spoiler:there is a considerable movement of revolutionary-minded Etoiles led by Sakura's brother working behind the scenes to reform the society]].

* ArrangedMarriage: Sakura is engaged to Erika, even he doesn't have any special feelings for her (unlike her for him).

''Love Gene XX'' (a.k.a. ''Love DNA XX'' and ''Renai Idenshi XX'') was a YuriGenre manga that ran in ''Magazine/YuriHime'' between 2009 and 2013. It was written by Eiki Eiki and illustrated by Taishi Zaou--a duo best known for their BoysLove works (and ''Manga/HaruNatsuAkiFuyu'')--and is, as a result, a rather unique [[GenderBender blend of yuri and yaoi tropes]] that profoundly challenges the concept of traditional gender roles in a patriarchal society.

* SingleGenderSchool: The Kingdom plays with it. Technically, it's a single biological sex school (just like every other school in the setting), but it also segregates by gender: Adams and Eves attend different campuses and are only allowed to encounter each other every once in a while on a "neutral ground" between the two.

* GenderFlip: The bonus chapter ''Love DNA XY'' reimagines the series as a BoysLove story with an all-male cast.

* KissOfLife: After Aoi seemingly drowns, Sakura panics and attempt to give him CPR--it turns out, he was just momentarily unconscious, and this was their respective FirstKiss.

!!The manga contains examples of following tropes:

* MortonsFork: Inverted. When Aoi demands that Sakura becomes his friend if he gets better grades in the upcoming exams, Sakura reciprocates that if ''he'' wins, Aoi will have to become his ''best'' friend. [[spoiler:Towards the end of the series, they are force in a very similar situation again, basically having to fight over who of them becomes an Eve.]]

''Note: Because Adams are referred to with masculine pronouns in original Japanese, the same convention will be used in the following article.''

In the 21st century, humanity was hit by a virus that affected male chromosomes, causing all babies to be born female. In 2122, the last man on Earth died, and the now all-female world adopted the "Eden Project", under which half of the planet's population would carry out traditional masculine gender roles as "Adams", while the rest would continue to bear children as "Eves". In 2160, an Adam named Aoi Koshiro enrolls at the prestigious Kingdom Academy with an express goal of becoming its top student--a position [[TheRival currently occupied]] by Sakura Kokonoe, a ridiculously attractive and successful Adam from a privileged and rich family. Before long, Aoi's rivalry with Sakura gives way to feelings he cannot quite comprehend.
