The conflict spilled out of the prison and culminated at the Kennedy Space Center at Cape Canaveral. The location and the timing (a new moon) were the final prerequisites for the ritual.
Jotaro Kujo, having his discs restored by the Speedwagon Foundation, arrived to assist Jolyne and her allies in a desperate final battle.
Upon reaching the correct spatial coordinates in the sky, Pucci's C-Moon evolved into its ultimate, god-like form: Made in Heaven.
Made in Heaven began exponentially accelerating the flow of time across the entire universe, affecting everything except living organisms and Pucci himself.
In the ensuing chaos, Pucci systematically slaughtered Anasui, Ermes, and Jotaro.
Realizing they could not win, Jolyne sacrificed her own life to hold Pucci back, buying enough time for the child, Emporio, to escape into the accelerating timestream.
