Vanishing World

In a near-future Japan, sex between married couples has become taboo and almost every child is born through artificial insemination. Amane Sakaguchi is quietly horrified to learn she was conceived the old-fashioned way — a shameful anomaly in a world steadily engineering romance and the family out of existence.

As an adult in a chaste marriage, she and her husband move to Experiment City, an "Eden" where children are raised communally, called only "Kodomo-chan," and belong to everyone and no one. A chilling, deadpan interrogation of love, motherhood, and normality from the author of Convenience Store Woman.
