About
Heaven's Door allows Rohan to read others' minds by turning their body into a book. The ability is activated when one sees his stand or a drawn image of his stand. With his artist skills and quick hands he can even create an image in midair with a mere pen. Contents inside are the person's memories since birth. The "pages" of the book can be ripped out, causing them to lose those memories and lose body weight. Furthermore, the stand user has the ability to write on the blank pages of the book that represents the future memories of the victim. So if he wrote into the blank pages "You can not attack [this person]", the victim will do as it was written like a hypnotic suggestion. The contents shown by Heaven's Door are all the thoughts, ideas, and memories of the individual, so there is no way for the user to lie unless he/she their self does not know. Heaven's Door also seems to grant the ability to write at superhuman speeds, as Rohan was able to make his deadlines even when Stairway to Heaven (Made in Heaven) was accelerating time.
Heaven's Door also seems to appear as a character in Rohan's "Pink Dark Boy" comic series, at least it shares the exact same appearance as the (possibly main) character when Rohan once is seen working at his desk.
