What a freaking mouthful of a title. Not to mention I'm not familiar with these characters and apparently in-series they're actually Chinese and yet they have JP-readable substitute names but the author is Chinese but he used the JP names in the title of the JP version of the book so...argh. Anyway, I found this on Nyaa, so this is very much not my scan. It's also not available digitally as far as I can tell--only the Chinese version is as of this writing.
As such, if you want to buy a physical copy for yourself of this amazing book, get it here: https://ec.toranoana.jp/tora_r/ec/item/040030716127
