The TV anime series Jinrui wa Suitai Shimashita - airing in Japan from July 2012 - is created by studio AIC A.S.T.A., based on a fantasy light novel series authored by Romeo Tanaka (who also authored Aura: Maryuuinkouga Saigo no Tatakai), with illustrations by Touru Yamasaki (the first six volumes) and later by Sunaho Tobe. The story is set several centuries into the slow decline of mankind. Earth has now become the realm of "fairies" - 10-centimeter / 4-inch tall creatures with remarkable intelligence and an appetite for sweets. The human protagonist of the story serves an important duty as the international arbitrator between the fairies and humans, and she returns to her former hometown of Kusunoki. She chose this job because she thought it was an easy job she can do, even when she is as old as her grandfather. However, she learns that her job is anything but simple when she meets the fairies.
