Heaven's Door

Heaven's Door is the Stand of Rohan Kishibe, featured in Diamond Is Unbreakable, and in the Thus Spoke Rohan Kishibe One-Shot series featuring Rohan.

Appearance
Overall, Heaven's Door resembles a small boy. Rohan may summon it or induce its effect with certain paper drawings; or an air drawing in its image, when it is invisible save for its outlines. Later, it commonly manifests in a solid and three-dimensional form; light in color, retaining thick outlines or seams.

It wears a long overcoat, closed to the end of its torso, and a bow tie. Lines emanate from the bottom and the bottom-outsides of its eyes. Its flat-topped hat is similar to a boater – In later stories it more closely resembles a bowler hat, while in its first appearance (in Rohan's "Pink Dark Boy" manga), it wore an opaque fedora.

Abilities
Heaven's Door acts when Rohan's target sees it or an image of it drawn by him, which he can make in mid-air, with a pen or with his finger. It can affect multiple targets.

Book Transmutation: Heaven's Door's basic ability is to turn people into books, pages unfurling from their bodies, revealing detailed and absolutely true information on their subject, including physical characteristics, memories and thoughts from their earliest to their latest, personality, and any details on their Stand. Targets may be incapacitated to varying degrees while under this effect. Rohan cannot read his own memories, nor perceive memories he shares with his target.

A dying person's details are seen to gradually disappear. However, Heaven's Door is effective on both ghosts and the undead (as shown on Reimi Sugimoto, and zombie-like spirits in Rohan at the Louvre). In animals, details comprise relatively literal descriptions.

Memory Removal: By removing pages, Rohan causes his target to lose any memories detailed there, along with a proportionate quantity of body mass.

Write-In Command: By writing into these pages, Rohan may create artificial memories, or make highly effective commands. Rohan's target will obey commands written into them closely, even against mental resistance (despite a phobia of immolation, Okuyasu is forced to hold a lighter to himself). Otherwise impossible tasks may also be made possible (after commanding Josuke to fly backwards at 70km/h, he does, without external force). Rohan has also given Koichi the ability to speak Italian. While Rohan cannot read his own memories, he may write commands for himself (writing on his forehead, he commands himself to repress all memory of the events of Rohan at the Louvre, though they return after the command rubs off).

Trivia

 * In an interview, Hirohiko Araki mentions that if he were to have any Stand, it would be Heaven's Door.
