As far as I am aware - and concerned - three universes have been visually portrayed in the JJBA manga: the Phantom Blood Universe which ends at the events of Stone Ocean once Made in Heaven resets the universe, the Irene Universe where Irene and other parallels of the characters of the Phantom Blood Universe exist which came about as a result of Enrico Pucci's antics and effectively replaces the Phantom Blood Universe, and the Steel Ball Run Universe which does not replace the Phantom Blood Universe or runs within the Irene Universe but rather unfolds separately from them while containing its own character and plot parallels.
