So for someone with little to no interest in continuing JoJo can you tell me what is the connection to stone mask vampires and pillar men? Any discussion of the solar power from the 2nd part?
There's some implications that Hamaon is fundamentally the same kind of power as Stands, though far weaker/less manifested. But aside from that, the connection there is basically entirely Dio - The plot threads with the stone mask (Aside from Dio being a vampire) and pillar men are entirely closed at the end of part 2. Dio is the villain again in Part 3. An illiegtimate son of his is the protagonist of part 5. A confidant/follower of his is the villain in part 6. Part 4 doesn't have a big, direct connection, though it does have a few minor ones. And part 7 reboots the series into an alternate timeline where Stands are essentially a thing from the start
