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 ...

Mixed Feelings
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 ...

Preliminary (5/11 eps)
This show presents sexual assault about as well as hentai. It's just so bad that I found the show to be completely unwatchable after episode 5, which is a shame because the rest of the show is pretty good. The SA in episode 1 was pretty pointless and gratuitous, but at least it didn't have the hentai shit where people like getting raped which is what happens in episode 5. If you can tolerate that garbage, then great there's a lot to like about this show; if not, then skip.

Everything ignoring the sexual assault: 8/10
Not ignoring the sexual assault: 2/10
