For years, declining birth rates have forced what's left of the human race to cede more and more territory to other beings who have appeared to take advantage of the emptying ecological niche. Now, only a handful of humans remain among the remnants of civilization and Earth is dominated by faeries —tiny, ten-inch tall creatures of surprising intelligence. But humanity's importance isn't over quite yet, as young Watashi learns as she makes the decision to return to her hometown and assume her grandfather's position as an arbitrator between the races. Unfortunately, the job isn't going to be anywhere near as simple as she expected, and it's going to take a wisdom far beyond her years to achieve her most important mission.

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~.

"I always thought of humans as intelligent dominoes, since they tend to follow each other." — Okashi-chan

Humanity Has Declined is sure an interesting title for an anime, it’s one of those that let our imagination fly freely trying to guess what the anime is about before even start to watching it, sometimes this lead us to imagine a complete different anime from what is in reality, leaving in us a satisfactory feeling, or in others cases, a pinch of disappointment when we actually find the true after watching the first episodes, revealing to be something completely different read more

Humanity Has Declined Review

Welcome ladies and gentlemen to my review of Humanity has Declined, let’s get started!

The Story
The story of Humanity has Declined is set in a world where the decrease in birth rates have caused the population of humans to decrease giving rise to “new humans” known as fairies who possess technological advancements. We follow Watashi as an arbiter of sorts between the fairies and the humans as she tries to investigate the fairies and their behaviors which lead to some convoluted adventures.

The main thing to acknowledge about this title is the fact that this is a comedic satire that pokes read more

Watch out for the fairies. Otherwise you can be tricked in to liking the Jinrui wa Suitai Shimasita series.

Bizzare, scattered, peculiar. The storytelling of Jinrui wa Suitai Shimasita, also known as "Humanity has declined", is similar to popular series like Baccano and Suzumiya Haruhi. The plot was hard to follow as it was told in a very random, non-linear manner, and I am not quite sure what the director was aiming for. For this reason I would recommend to watch episodes in the following order: 10, 7, 8, 3, 4, 9, 5, 6, 1, 2, 11 and 12. By this the read more

Anime: Mawaru Penguindrum
These Anime take the world and twist the reality. What could possibly be a normally a happy go lucky story line has dark twists to it.

Anime: Sayonara Zetsubou Sensei
Almost the same type of humor

Anime: Yojouhan Shinwa Taikei
Both deal with human nature and doubts in metaphorical way.

Anime: Tsuritama
Both of these Anime have very different story lines, but they have a similar art style and they take their genre and do something different with it.

Anime: Kamisama no Inai Nichiyoubi
In both, mankind numbers dwindle to very low. Atmosphere seems similar too 
reportRecommended by hexaq
Anime: Moyashimon
The main characters in both shows are witty and sarcastic and have unique communications with tiny, cute creatures. A similar dark humor is frequently used in the two series that appeals to a more mature audience. Both shows also have clear morals about society.
