Fehu Kazuno is the original creator behind the Japanese multimedia franchise Apocalypse Bringer Mynoghra, which began as a web novel. The series, known in Japan as Isekai Mokushiroku Mynoghra: Hametsu no Bunmei de Hajimeru Sekai Seifuku, first started serialization on the user-generated novel publishing website Shōsetsuka ni Narō in November 2017. The work was later acquired for traditional publication, and the first volume of the light novel was released in November 2019 by Micro Magazine under its GC Novels imprint, with illustrations provided by the artist Jun.

The success of the light novel led to an expansion of the series into other media. A manga adaptation illustrated by Yasaiko Midorihana began serialization in March 2020 on Kadokawa's ComicWalker website. The manga has been released in compiled volumes by ASCII Media Works under the Dengeki Comics NEXT label. In the English-speaking market, the light novels have been licensed by Cross Infinite World, while Yen Press holds the license for the manga adaptation.

The series achieved a significant milestone with its adaptation into an anime television series. The anime, produced by the studio Maho Film, premiered in July 2025. The original work by Kazuno has thus been adapted across all major formats of Japanese media publishing, establishing Apocalypse Bringer Mynoghra as a central part of their creative output.
