In pocket monsters the others mangas are labed has "Contains", so i guess it means instead of spin-offs, this mangas are in the same universe but not really sequels or spin-ofs, probably just some Arcs that got they own manga, either way, this means that JoJo won't have this happen since the current arrangement is the correct and most fit, in Pocket Monsters it only stays like that because of the "Contains" label.
Hope i didn't missunderstood.

So there are sort of chapters between the arcs of Pocket Monster, and that's why there's this entry for the whole series? If this is the requirement then it makes sense for JoJo not to have an entry for every series then. Thanks for the info
