Synopsis
The gods appeared when humanity was on the brink of destruction due to the work of the demons. Thus, the deities called "Idaten" fought and sealed the demons away 800 years ago. Nowadays, the Idaten have no experience in combat and live a peaceful life. But now the demons are reviving, and the battle between gods, humans, and demons is about to begin.
Coolkyoushinja launched the manga in Young Animal in August 2018. The manga is a remake of Amahara's web manga of the same name.
Ademis, the manga Interspecies Reviewers by Amahara and Masha, inspired an anime that premiered in January.
Finally, several of Coolkyoushinja's manga have already been adapted into anime, such as: Miss Kobayashi's Dragon Maid, I Can't Understand What My Husband Is Saying, and Komori-san Can't Decline.
