the vengeful ghost of a young psychic who was murdered and thrown into a well. As a ghost, she is dressed in a simple white dress usually with long black hair hiding her face, and uses nensha, her most distinctive power, to create a cursed videotape; whoever watches the tape will be haunted by Sadako and die exactly one week later unless the tape is copied and shown to another person, or unless she willing spares the person who watched it, in this case after you watched she choose to spare you.
