Why does everyone hate Joshu? what did he do wrong? Everything he did in the past 2 chapters is completly understanable from his point of view. ya'll are just hating him for the sake of hate.
because ireneverse was created by made in heaven, while SBR universe is just an au created by araki, to get a kinda clean slate, with no relation to the ireneverse
Irene has the birthmark which means she is a joestar, but her existence doesn't match up with the family tree of parts 7/8.
The ending of part 6 is basically a reset/cancellation of MIH's reset. The universe is mostly the same as it was before with some diferences due to MIH killing jolyne/jotaro/anasui/hermes etc.
The SBR universe is a separate continuity from the original 1-6 storyline. The names of characters and stands are nothing more than references for jojo veterans to fanboy over.
