Vanishing World

In our near-future world, children are solely conceived by artificial insemination. Even sex between married couples is viewed as taboo.

But Amane falls in line with society's way of thinking and wants a regular 'clean' marriage. Then she hears of a place that is the subject of a social experiment. Everyone in Paradise-Eden will act as one big family. Could this be the perfect third way?
