DIO's Diary

The journal, known also as The Way to Heaven, sets down in loose terms DIO's method for attaining what he names Heaven. Jotaro Kujo comes upon it in the wake of Stardust Crusaders and, sensing its danger, sets it alight. The trouble is that he still recalls what it said, and because those memories survive, Pucci fixes on extracting Jotaro's Memory Disc to claim the recipe for himself.

As Jotaro remembers it, the plan opens by requiring DIO's Stand, The World, since what lies beyond its power is the road to Heaven. It calls for a wholly trustworthy companion, someone who masters his own urges, cares nothing for power, fame, riches, or lust, and places God's will above human law. It further demands the lives of more than thirty-six people who have sinned, on the reasoning that sin leaves a strong power within, along with fourteen set phrases, among them spiral staircase, rhinoceros beetle, and singularity point, to be fixed in mind and carved onto the Stand.

The final steps ask for the nerve to briefly destroy the Stand, which as it breaks apart is meant to drink in the souls of the thirty-six sinners and give rise to something entirely new that will awaken and respond to the fourteen phrases spoken by the trusted friend. It closes by naming a precise spot, near latitude twenty-eight degrees north and longitude eighty degrees west, where one must wait for a new moon for Heaven to arrive.

The diary is DIO's own work, though how he learned its formula is never explained. Jotaro discovers and burns it, then unwittingly carries it forward as memory, while Pucci hunts that memory to enact the scheme. In Part 6 the pieces line up: Pucci becomes the trusted friend, the prison supplies the thirty-six sinners, DIO's Bone stands in for The World, Cape Canaveral is the appointed place, and the plan culminates in the Stand Made in Heaven.
