Eight hundred years ago, terrifying demons threatened mankind's existence. On the brink of extinction, humans prayed to their gods, calling out for someone to save them. Emerging from these desperate pleas for salvation, battle deities known as the "Idaten" were born. Possessing unnatural strength and endurance, the Idaten managed to defeat the demons and an era of unprecedented peace was finally ushered in.

Having never encountered demons before, the present generation of Idaten knows nothing of the demon's brutality, but they have instead only lived a peaceful existence. Training under Rin, the only remaining Idaten from 800 years ago, the new Idaten find ways to survive in a time where they have seemingly outlived their usefulness. However, when the tyrannical Zoble Empire resurrects a demon, the misfit crop of gods are called to the battlefield against their natural enemy once more.

This show is the reason why 3 of the most notable entities exist: Interspecies Reviewers, Miss Kobayashi's Dragon Maid, and MAPPA. What, you still cannot figure out what sets Heion Sedai no Idaten-tachi a.k.a "The Idaten Deities Know Only Peace" apart? Then go figure and find your own peace treaty in a wild wonderland world.

Written by Amahara, illustrated by Cool-kyou Shinja (of which this is the 3rd work of 3 featured in this season, damn this author is rekting the Summer season hard) and produced by MAPPA. Announced as one of many shows at the MAPPA Stage 10th Anniversary event under debut director Seimei Kidokoro's read more

Imagine taking a great portrait like the Mona Lisa, and then furiously splashing it with buckets of different colored paint. What you get is essentially this filth of a series, and from the likes of Studio MAPPA, no less.

Idaten Deities advertises itself as brainless “style over substance” entertainment, but it turns out be something far more inherently vulgar than what people wanted to acknowledge or admit. It isn’t so surprising when it turns out to be written and created by the same author who did Interspecies Reviewers, which itself was quite the shameless example of anime pornography, for better or worse. As read more

Perhaps it's time to play Devil's Advocate.

Idaten Deities is certainly an oddball among the Summer 2021 line-up. By far one of the most lavishly animated, stylistically interesting, and well-produced shows of the year has been largely ignored, and similarly written off as nothing more than incomprehensible edgy garbage that's "style over substance".

What a silly pain in the ass this buzzterm is. It's nothing more than an excuse for people to dismiss a well-animated work they don't like because the writing isn't trying to be the 10/10 kino that the visuals are. It's not because the writing actually gets in the way of all the spectacle read more

The only other manga from this creator with an anime adaptation is Ishuzoku Reviewers, and my problem with this show is the same as my problem with that one. In both cases, you read the premise and think, “that’s genius,” but then you actually watch the show, and it’s just mediocre. The idea is that once upon a time, demons ravaged the Earth and drove humanity to the brink of extinction, so deities came down to seal them away and save humanity. Centuries later, humans have become their own worst enemy, killing each other for politics, power, religion, militarism, expansionism, the usual. However, the deities read more
