It has come to the time where, at long last, all of the Jojo light novels have been translated to English (at least unofficially, through fan-effort). Genesis of the Universe marks the first that I was able to complete, working chronologically from the beginning of the manga onward (with full knowledge of what had already been adapted into the anime up to Part 5). For anyone attempting the same, I'll note that both the Jorge Joestar and the Over Heaven novels (taking place pre-Part 2 and during the events of Part 3) had elements mentioned for characters I knew to be main antagonists in bothParts 6 and 7, with special emphasis on "homework" needed on the Jorge Joestar novel because there are some original-works-character and extra-alternate-universe nonsense going on with that one too (which I'll go into further detail on for its own review), so I felt compelled to stop partway and wait until I reached those parts of the manga.

As for Genesis of the Universe, for anyone struggling to find an English translation, I found a source using the translator's Twitter account, to be downloaded in conjunction with Golden Heart, Golden Ring, and some odd fixed pages of the Stone Ocean manga. I appreciate the work done here especially considering the translations being cross-referenced with what is apparently the VERY poor translation job done for the Italian release. If I were to make a couple of changes, I would want to respell "Abdul's" name as "Avdol" and to use quotation marks for dialogue instead of "-", but at this point, I feel those are nitpicks. I linked below.

The actual stories contained therein are ok, and skippable for sure, but enjoyable all the same. Like otherwise noted, they are simply a couple more adventures against Stand users during the Egypt arc of Stardust Crusaders. The imagination for a couple of the origins and abilities I found impressive, and the artwork serves as adequate illustrations ranging from super-impressive manga work to a couple that perhaps looked more like sketches? It all averages out, honestly.

Overall, a few more chapters worth of villain-of-the-week that we didn't have before, just in the form of prose instead of manga. I say it's worth the read.
