Humanity has Declined

Finished

人類は衰退しました

Humanity has Declined takes place centuries after the decline of the human race due to plummeting birth rates. The most prosperous species on Earth are now the Fairies, tiny, highly intelligent beings only ten centimeters tall. The story follows a young woman who serves as a UN arbitrator between the dwindling human population and the whimsical Fairies, returning to her rural hometown to assist her grandfather.

Her job, which she initially assumes will be simple, quickly proves otherwise. Her first visit to a Fairy habitat to formally greet them spirals into a series of bizarre and surreal misadventures. As the arbitrator, she must navigate the Fairies' illogical societies, their strange customs, and their often dangerous, candy-fueled inventions, all while trying to maintain a semblance of order and understanding between the two species.
