JJK was immediately popular
Volume 1 debuted at just under 30k sales, which is good, and it was breaking 100k by Volume 3, far more impressive than what KnY made pre-anime
JJK never needed any handholding the same way KnY needed Ufotable and the pandemic
Even with all these veteran mangaka like Togashi and Akimoto shilling it, it never made any significant progress in sales or popularity. The anime was pretty much its final chance to improve sales because the manga as a standalone product isn't good
