Humanity Has Declined (人類は衰退しました Jinrui wa Suitai Shimashita?), or Jintai (人退?) for short, is a Japanese light novel series written by Romeo Tanaka. The novels originally featured illustrations by Tōru Yamasaki for the first six volumes, but Yamasaki was replaced by Sunaho Tobe in 2011. Shogakukan published 11 volumes from May 2007 to September 2016. Three manga adaptations have been produced. An anime adaptation produced by AIC A.S.T.A. and directed by Seiji Kishi aired in Japan between July and September 2012. Sentai Filmworks has licensed the anime in North America.
Humanity Has Declined is set in a post-apocalyptic world where the human civilization has regressed and humanity keeps decreasing in numbers. The story follows an unnamed girl who acts as a mediator between humanity and the "fairies" who are small elf-like creatures attracted by sweets and happy things, but also have the habit to cause trouble to her with their powers in their endless search for amusement.
