JoJo No Kimyou Na Bouken consists of currently eight parts, which each feature a different set of characters - sometimes they overlap, but more often then not you can start reading at every part without further background information required.
Yet, only Steel Ball Run (Part 7) and JoJolion (Part 8) are tagged. Some may argue there are reasons for this since SBR is basically the start of a complete reboot for this series and much longer than any other part so far, but I think it would greatly help the search for part-specific fanart if we could create more subtags for this series - much like Precure or Kamen Rider. Of course, each subtag implies the main series for an overall search in this case.
Is this reasonable because of the differences between each part or should we just leave it as it is?
