What is Humanity Has Declined?#
Humanity Has Declined (also known as Jinrui wa Suitai Shimashita) is a unique blend of science fiction, comedy, and supernatural adventure. The story takes place several centuries after the human population has declined, leaving the world to be dominated by “Fairies”—intelligent, 10cm tall creatures with an obsession for sweets.
The plot follows a nameless girl who serves as a UN arbitrator between the remaining humans and the fairies. After returning to her hometown to assist her grandfather, she, the grandfather, and a nameless boy find themselves investigating mysterious products sent by a company known as FairyCo. If you are looking to dive into this whimsical yet political post-apocalyptic world, you can watch the anime on Prime Video.
Is the Anime Really Finished?#
For viewers wondering if they can commit to the series without worrying about a cliffhanger, Humanity Has Declined premiered in 2012. While the anime provides a distinct experience, those who find themselves captivated by the world-building—specifically the complex relationship between humans and the FairyCo entity—may find that the anime is only one part of the story.
To get a truly comprehensive conclusion or to explore the lore in greater detail, we recommend continuing with the source material. You can buy the manga or light novel here to see where the story goes beyond the animated adaptation.
Themes and Audience Appeal#
This series is best suited for audiences who enjoy “soft” post-apocalyptic settings where the focus is more on satire and surrealism than on survival horror. The anime explores several intriguing themes, including:
- Political Satire: Through the lens of a UN arbitrator and the corporate machinations of FairyCo.
- Whimsical Surrealism: Mixing fairy tales and magical creatures with high school elements and robot girls.
- Melancholy and Comedy: Balancing the decline of humanity with the absurdity of fairy society.
If you enjoy stories that blend high-concept science fiction with supernatural comedy, this is a must-watch. While you’re enjoying the show, why not pick up some Humanity Has Declined merchandise to show your support for the series?
