Character

Sadako Yamamura

山村貞子

Sadako Yamamura (山村 貞子 Yamamura Sadako) is the central character and antagonist of Koji Suzuki's Ring novel series along with its numerous film and television adaptions. Her name combines the Japanese words for "chaste" (sada) and "child" (ko). Sadako's fictional history alternates between continuities, but all depict her as the vengeful ghost of a young yet troubled psychic who was brutally murdered and thrown into a well in an attempt to stop her powers from spiralling out of control. As a ghost, she uses nensha, her most distinctive power and weapon, to create a cursed video tape that will kill whoever watches it exactly one week later unless the tape is copied and shown to another person, who then must repeat the same process.
