For full context: Unlike Gensokyo of Humans and Magician Who Loved a Fake, which were published through Strange Creators of Outer World, this is Ashiyama's self-published doujin that's been going since 2015. He's been working on it before, in between, and sometimes during those other series.
Most of the series has been originally published as books, which were then divided into chapters for the Pixiv release used here.
