Rohan Kishibe is a Japanese individual of average build and height. He has a green undercut that is slicked sideways. While he regularly changes outfits, Rohan keeps his trademark headband with serrated edges and fountain pen-tip earrings in every appearance. Rohan's outfit consists of a white crop-top jacket buttoned with pen heads over a green crop-top shirt, and baggy white pants. Rohan Kishibe is a passionate manga artist dedicated to his work, with a particularly abrasive personality but a good heart. Rohan Kishibe is above all defined by his dedication to his work. With great draftmanship talents, Rohan has constantly sought to make the best manga possible in order to keep being read. His wish to be read is so great it trumps any other motivation, disdaining money or glory. When drawing, Rohan falls into an artistic trance, drawing with abandon and being distracted with great difficulty. Because of his tremendous drawing skill, the one thing Rohan seeks the most is inspiration to fuel his work as everything else is an effortless formality.   To gain inspiration, Rohan is constantly seeking new experiences or facts, investigating anything he might find interesting with blatant disregard for common sense, politeness or the law, for instance constantly prying into people's lives by turning them into books with his Heaven's Door. Moreover, Rohan is overly curious, willingly throwing himself into strange adventures such as an unusual house sale or a poaching session. His inquisitiveness can turn obsessive and downright morbid. Nonetheless, Rohan considers "reality" to be the greatest inspiration, and looks for genuine material, disdaining fakes. Rohan looks down on everyone but himself, Koichi, and Guest. Parallel to his artistic passion exists Rohan's general unpleasantness. Rohan is arrogant, being aware of his nearly superhuman skill as an artist. Thus he generally looks down on everyone else and may only see people as possible material for his manga. Naturally, Rohan also hates being made a fool of. His arrogance is paired with his constant coarseness. While he may act with professional courtesy, Rohan is generally brash and impolite. Maintaining a thin veneer of civility, Rohan will usually make no secret of what he thinks of people which, combined with his arrogance, often earns him a mutual disdain with his interlocutors. Rohan blatantly disregards courtesy for the sake of his goals, turning people into books on a whim.

Heaven's Door resembles a small humanoid with the appearance of Rohan's manga character, Pink Dark Boy. It wears a long white overcoat, closed to the end of its torso, and a yellow bow tie. Its face has an outline that connects to lines emanating around its eyes. It also wears a transparent top hat with a yellow checkered pattern at the bottom. Heaven's Door enables Rohan to transmute people into "human books", with written pages unfurling from their bodies. These pages relate detailed information about that person, including biological characteristics, history, personality, or even details of their Stand and its abilities. It was acquired when he was shot with the Arrow and its nature likely originated from his zeal for drawing manga. Heaven's Door's simple yet exceptionally versatile power to transform people into books makes Rohan a formidable Stand user. Rohan liberally uses his power to write commands in people, but usually shows restraint and subtlety in writing said commands. He prefers using very specific orders to compel people into not doing one thing or performing a single task for him, but never more. As a manga artist, he frequently uses his power to pry into people's lives for inspiration, regardless of courtesy.
