Kayako Saeki

"When someone dies in the grip of a powerful rage... a curse is born. The curse gathers in that place of death. Those who encounter it will be consumed by its fury."

- The Grudge's opening text Kayako Saeki (佐伯　伽椰子) was a Japanese housewife living in her household in Tokyo alongside her husband Takeo and son Toshio. After being brutally murdered by Takeo due to speculation of an affair, Kayako's spirit transformed into an Onryō --- vengeful spirit that terrorizes the living world after death.

After executing her revenge and murdering everyone in her household, Kayako, now with the spirit of Takeo and Toshio under her command, became the main antagonist in Jun-on series and continued to lurk around her household. From then on, everyone that enters the house will become Kayako's victim.
