In the year 2999, only eleven cities still survive on Earth. The climate has changed drastically, and a biochemical apocalypse has made women extinct. For centuries, the male population of Earth has survived by depending on only one woman, called the Holy Mother, whose ova are harvested to create genetically engineered children. By now, any concept of a world in which women exist as ordinary people is long gone. Society has re-structured itself around all-male families, and relationships between men and adolescent boys have become the norm. At the beginning of Marginal, the Holy Mother is assassinated by a terrorist known as Grinja. The government in power doesn't want to start a mass panic, so it pretends that the Holy Mother has only shed her vessel, and that she will be miraculously "reborn" in the near future. The public, which is superstitious and devout, believes this easily. Only government officials know that behind the scenes, there is a frantic effort to create a being able to give birth. The manga's story revolves around Kira, who becomes involved in a three-way relationship with Grinja, and Ashijin, a young man who calls himself Kira's owner.
(Rec applies to the earlier volumes of both, later volumes are vastly different)
Marginal and Andromeda Stories are early-80s science fiction manga from extremely influential shoujo mangaka. Both are soft sci-fi, and tend to blur the distinction between science fiction and fantasy. Both are set in a desert dystopia loosely modeled after a mish-mash of Middle Eastern cultures.
I liked Marginal much better- the story and characters seemed better developed/less generic, while Andromeda Stories was kind of hokey (it hasn't aged as well).
The future. Having driven Terra to the brink of environmental collapse, humanity decides to reform itself by ushering in the age of Superior Domination (S.D.), a system of social control in which children are no longer the offspring of parents but progeny of a universal computer. The new social order, however, results in an unexpected byproduct: the Mu, a mutant race with extrasensory powers who are forced in exile by The System. The saga begins on educational planet Ataraxia, where Jomy Marcus Shin, a brash and unpredictable teenager, is nervously preparing to enter adult society. When his Maturity Check goes wrong, the Mu intervene in the great hope that Jomy, who possesses Mu telepathy and human physical strength, can lead them back home, to Terra..
