HEAVENS DOOR

 Heaven's Door (ヘブンズ・ドアー（天国への扉） Hebunzu Doā) is the Stand of Rohan Kishibe, featured in dIAMOND IS uNBREAKABLE, and in the tskr One-Shot series featuring Rohan. 

Heaven's Door is initially introduced as an ability without an appearance, but takes on a full-fledged body in later arcs.

Heaven's Door resembles a small boy similar to Rohan's manga character, Pink Dark Boy It wears a long overcoat, closed to the end of its torso, and a bow tie. It has lines emanating 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.

Rohan may summon it or induce its effect with certain paper drawings; or an air drawing with his finger in its image when it is invisible save for its outlines.

Heaven's Door is portrayed as being white with golden outlines across most media featuring it, except the OVA where the outlines become blue. 

 

Heaven's Door is a weak close-range Stand unsuited for direct combat, but has several powerful abilities. For an inquisitive mangaka like Rohan, Heaven's Door is a handy way to gather research material out of people's pasts without the hassle of an interview.

During its introductory arc, 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. However, closing one's eyes or being simply unable to process the image, like being filled with rage, will make the opponent immune to Heaven's Door.

Later on, Rohan can simply summon his Stand and approach people to affect them.

Heaven's Door's basic ability is to turn people into books, pages unfurling from their bodies in the shape of whatever body part it opens from (for example, if from the face, the shape of the pages is of the person's entire face, eye holes included). Targets may be incapacitated to varying degrees while under this effect, from barely being able to walk to being completely knocked out.

The contents of the books contain detailed and absolutely true information on their subject, including physical characteristics, personality, and all of their memories and thoughts from their earliest to their latest. The pages also include details on the victims Stand, if they have one. Rohan was even able to use this ability on a chicken leg to determine its expiration date. However, Rohan cannot read his own memories, nor can Heaven's Door reveal any information and memories that his target knows about him.

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.

Occasionally, it is shown that since people under the effect of Heaven's Door literally turn into books, Rohan can also use this forced physical transformation to his advantage. Rohan has notably used this power to literally unravel Okuyasu's limbs and at another time, save someone from being crushed by two speeding trains by transforming their body into a book and flattening it enough to fit between the trains^.
