The dormant virus infected the ovulating Mai Takano when she watched the tape, causing her to give birth to a Sadako clone who assumed the name Masako. She was described as a "complete hermaphrodite" as she had fully functional male and female reproductive organs. After her identity was outed, Sadako revealed to Mitsuo Ando that she made a deal with Ryuji: in exchange for his resurrection, he would help her be reborn, something he did when he attracted Ando into the case. She then blackmailed Ando: in exchange for not activating the dormant ring virus that he contracted when he read Kazuyuki's journal, he would refrain from stopping it from being published. As an incentive, Sadako, who had the ability to clone a person by implanting their genes into her, would birth his deceased son, Takanori, back to life. Realizing that Sadako would have won no matter what he did, Ando reluctantly cooperated.
