Humanity Has Declined

人類は衰退しました

It has been several centuries since human population has declined. Food has become harder to find and what little sources the humans have are considered highly valuable. The most prosperous species on the Earth are "Fairies", 10 cm tall creatures with high intelligence and a great love for sweets. A nameless girl, the main character, became a UN arbitrator between the humans and the fairies and had returned to her hometown to help her grandfather. One day, the village is sent some strange products made by a company called FairyCo. Since the villagers are wary of using the products, the girl, her grandfather, and a nameless boy decide to go to the factory to find out about the mysterious products and who is behind making them.
