Synopsis

Humanity's been on a steady decline for centuries now—birthrates just kept dropping. Meanwhile, the fairies took over as Earth's dominant species. These tiny creatures, only about four inches tall, are surprisingly intelligent. So I ended up becoming a UN mediator between humans and fairies, and I figured it was a good time to head back to my hometown and help my grandfather out. I figured the job would be pretty straightforward, honestly. But then I decided to visit one of the fairy settlements to introduce myself, and. well, things got complicated.
