A Chinese girl, Li Yueqiu, discovered a world called Karazia in the drawer of the TV cabinet at her home. This is a wonderful world where animals and plants are alive and can talk. However, because 1,000 years ago, the dark witch Xilei established magic with the world. Since then, the world has been turned upside down. After a 24-hour long night, there is only a 12-hour dawn. So, at night, Xilai wrested the territory of animals and plants. The day time was too short, and the animals and plants could not grow strong quickly, so they had to obey Xilai in order to survive. The four children chosen by God: Chinese girl Li Yueqiu (Katherine), American boy John × Cassie, British girl Blair × Brown, and British Chinese William × Ankaru began a wonderful journey to another world!
