As a child, Natsuki doesn’t fit into her family. Her parents favor her sister, and her best friend is a plush toy hedgehog named Piyyut who has explained to her that he has come from the planet Popinpobopia on a special quest to help her save the Earth.

As a girl, Amane realizes with horror that her parents “copulated” in order to bring her into the world, rather than using artificial insemination, which became the norm in the mid-twentieth century. Amane strives to get away from what she considers an indoctrination in this strange “system” by her mother, but her infatuations with both anime characters and real people have a sexual force that is undeniable.

Amane is ten years old when she discovers she's not like everyone else. Her school friends were all conceived the normal way, by artificial insemination, and raised in the normal way, by parents in 'clean', sexless marriages. But Amane's parents committed the ultimate taboo: they fell in love, had sex and procreated. As Amane grows up and enters adulthood, she does her best to fit in and live her life like the rest of society: cultivating intense relationships with anime characters, and limiting herself to extra-marital sex, as is the norm.
