I'm Dio, son of DIO, and my mother is Chinese. Since she couldn't be bothered to give me a name, I inherited my father's.
"World" refers to Di Xiaoman, my cousin, who inherited my father's Stand.
"Emperor" refers to Diavolo, the villain and boss of this book.
After being struck by Gold Experience Requiem, Diavolo was pushed to the brink. In that desperate moment, he awakened a new Stand ability and escaped the reset. He then gathered DIO's remaining followers, intending to seize the arrows in the hands of Dio and Di Xiaoman, before going after Giorno for revenge!
Who will win: Di Xiaoman, with her dark will, Dio, with his golden spirit, or Diavolo?
