Marginal

The whole world is agitated. Holy Mother, the only individual capable of producing children, is aging and the future seems uncertain. In such circumstance, a group of people from the desert appear in the city, who show special interest in the Sanctuary. And why in a medieval-looking world do a modern invention such as helicopters exist and why do the people fear them?

Marginal is a Boys Love manga by famous creator Moto Hagio. The series stands out by intricate plot in a rich sci-fi and dystopian setting. At its core, the story explores the relationship between sexes, the role of reproduction in human's perception of the meaning of life, and the role of science in civilization. Also expect a lot of twists.

Tropes used in Marginal include:

• Ancient Conspiracy: The Marginal project
• Artificial Human: Kira and hir siblings, products of Ivan Alexandr's Mad Scientist-dom
• Lover and Beloved: In a world with no women, the relationship between adults and teenage boys is this.
• Mad Scientist: Ivan Alexandr. How he goes on and on about the role of the womb is creepy
• One-Gender Race: On Earth, women lost reproductive capability because of a disease, resulting in a world with only men.
• Two Lines, No Waiting.
• Values Dissonance: Deliberate. The disappearance of women has caused institutions that readers in the real world find cringe worthy (but normal to the inhabitants of Marginal) to emerge.
