In the last century, there was an isolated island country—Girl Island—located in the equatorial ocean in the center of the Pacific Ocean. It's hot, misty, and shark-infested all year round. There is the young female king Karina, a fifty-year-old female state master Danchu, a forty-year-old sorceress Lu Bimas, and a thirty-year-old female chambermaid Aditya who manages the queen's life. There is also a female chief in her forties, Amasa Lati. It covers an area of less than one million square meters and has a population of tens of thousands, all of whom are women. They have lived by fishing and farming for many years. The bark of a banyan tree on the island is extracted into silk and linen and woven into cloth. They speak the Amus language. The houses are all mushroom-shaped thatched houses built under a huge coconut tree, with a peculiar style. The king has his palace.
