Because of the constantly declining birth rates over many decades, human civilization is all but extinct. With only a few humans remaining, they survive in this post-apocalyptic world with what was left behind by the previous generations. Earth is now dominated by fairies, tiny creatures with extremely advanced technology, an obsession with candy, and a complete disregard for human safety.

A young girl who has just finished her studies returns to her hometown and is designated as an official United Nations arbitrator. Her duty is to serve as a link between mankind and fairies, reassuring each side that both races can live together peacefully. She imagines this task will be easy enough, but controlling the disasters created by the oblivious fairies in their pursuit of candy will require a lot more effort than she initially believes.

To learn and evolve is a natural process of human nature. But after countless mistakes, does this growth still hold any meaning? What then, if the consequences are so severe that amending the situation becomes impossible?

For Jinrui wa Suitai Shimashita, this is answered through a colorful world where humanity is on the verge of extinction, succeeded by a race of silly, mass-producing fairies bearing a constant grin. Adorable and amusing as they are, these little creatures are anything but auspicious. Repeating tragedy in situations of utter insanity, the fairies exist as a personification of humanity's follies, neatly told through a clever story of satire read more

~Multilangual review, English & Español: Humanity has Declined~

Humanity Has Declined is sure an interesting title for an anime, I bet it happened before, you know, suddenly our creativity starts to run to it's fullest in order to guess what's the anime's storyline, the possibilities are infinite, after all, imagination has no borders, it's like being under a spell which allows us to imagine complete different scenarios where we're able to push our ideals, characters personalities, story developments, plot twists, in few words, everything we'd like to see, but the spell isn't eternal, everything cease when we're forced to open our eyes, yes, we wake up read more

I am just so happy to be through with that show, I really could not stand it. Generally I came to it for the amazing art style but I only found a pile of jokes that really didn't entertain me that much.
The show has some interesting atmosphere for a comedy, and it sometimes give the feeling of something more dramatic but it's not funny enough as a comedy and not nearly interesting enough as a drama.
Character and story development is almost non existent. The main character is being slightly examined throughout the show but the characters around her are so wacky there's hardly one relationship read more

Based on the title, the average individual would probably conjure projections of some bleak and black post-apocalyptic world. Based on the show's artwork, the average individual would conjure preconceptions of some bright and fuzzy fantasy setting. It's really neither, and yet it's kind of both, and that's one of the things that makes Humanity has Declined both refreshing and intriguing.

Produced by AIC, Humanity has Declined was adapted from a light novel series of the same name by Tanaka Romeo. Direction was handled by Kishi Seiji, Script, by Makoto Uezu. Character designs, original and anime, respectively, were drawn up by Sunaho Tobe and Kyuuta Sakai. As read more
