In Japanese folklore there is a wish-granting yokai that resides in dolls and is known as hinnagami. They are created by a complex magical ritual of collecting earth from graves, shaping it into a doll and then leaving it on the roadside to be trampled on by 1000 people. But beware for they have a darker side. For every wish that is fulfilled the hinnagami will demand that another wish be made. This yokai is the result of human greed and the process carries on forever. Even after death, the hinnagami will continue to haunt its creator.
