As Kayako returned, the conflict between the two spirits temporarily allowed the girls and Keizo to escape the house. They retreated to a well, where Keizo explains that one must sacrifice themselves in order to trap both Sadako and Kayako in the well, to which Yuri volunteers. Just as she jumps into the well, Kayako accidentally merges with Sadako, thus creating a new, all-powerful spirit. The cluster descended after Yuri, possessing her body before breaking out of the sealed well a moment later. With this, the new spirit became a new curse.
