Made in Abyss: Official Anthology is a compendium of short comics set in the same world and with the same characters from Made in Abyss. It's a parallel series from the same publisher, Takeshobo, and with Akihito Tsukushi's blessing, that gathers the work of multiple guest professional artists to tell non-canon stories, with some of them being serious, while others are totally silly or humorous. It has been published on Webcomic Gamma, alongside with Made in Abyss, since 2017.

These are interesting times in the empire of Varnia. The imperial army may have broken the back of the invading army of Nebel, but at tremendous cost.
