Ghost is usually return to human world because they still hold a grudge and anger. Same with Hikiko, which inspires the emergence of many ghosts in Japan such as Sadako and the ghosts in the creepy horror movies such as The Ring. Hikiko is portrayed as a long black-haired girl with pale skin and scary looking face.
Hikiko was a young girl who had miserable life. She was treated very badly by her parents and friends. She was also continually despised and ridiculed by her classmates, so that one day she committed suicide. Be aware, Sadako can be very dangerous as she holds an extreme level of anger toward human race.
