This is a world where dreams exist.
Dreams are indeed the brain activities of human beings during sleep, and they are a world imagined by human beings unconsciously.
But to be more precise, dreams can be materialized.
Children's dreams may be a castle made of chocolate and candies, poor people's dreams may be a villa with a swimming pool, lovers' dreams may be a beach under the setting sun, scientists and fantasists' dreams may be an intelligent science fiction world that exists in the future...
The only people who can see dreams are dream eaters, and hunters whose job is to hunt dream eaters.
Grace is a hunter in this area. Because time has passed so long, she has forgotten where she came from and why she appeared here. She only remembers that hunting the Dream Eater is her only duty and the only meaning of her existence.
