It is revealed that the house seems to function beyond time and space, as the baby was in fact Toshiki, whose kidnapping by Kiyomi somehow happened in Odajima's past. Odajima experiences visions of his childhood, in which his sister, Kazuha, was lured into the attic by the woman in white, who gave him her baby. After finding Yudai's corpse, Odajima, Haruka, and detective Kosaka go to the house to find photos of Kiyomi's rape in the living room. Odajima, Haruka, and Kimie continue pursuing the case and search for Kiyomi. She is comforted by her long-dead friends Yoshie and Mai, who invite her to go with them. Kiyomi then drowns Yudai in the bathtub before going to the house, where she has a breakdown. She tells him that Toshiki is not their biological son, but rather a baby she adopted from the cursed house. Yudai visits Kiyomi, whom he is estranged with, to ask her for drugs. Meanwhile, Yudai is haunted by Toshiki's spirit. Keiichi surrenders to the police, but he is attacked by the ghosts of Chie and their unborn child, the latter of whom eventually kills him. An unknown woman invites him to have dinner before he returns home, finding that Chie's womb now contains a ringing telephone. Keiichi buries the fetus in the house's backyard. With it, he goes to the Haida residence, where Nobuhiko has committed suicide after killing Keiko. He proceeds to cut open her womb and take the unborn fetus. Her plan goes awry when Keiichi puts up a fight. Before doing so, she reveals that her baby was fathered by Nobuhiko. Nobuhiko and Chie plan to murder their respective spouses so they can be together, with Chie drugging Keiichi so she can kill him. The woman killed him and gave birth to their baby, but it disappeared. Before then, the house was occupied by a man named Hiroshi Sunada, who raped a woman. Odajima admits that he used to live in the house and was motivated to write a book about it after his family died not long after they moved there. Odajima, Haruka, and Kimie team up to solve the haunted house case. Meanwhile, Yudai's domestic abuse hits its nadir when he hits Toshiki with a telephone, sending him into a persistent vegetative state. Unbeknownst to them, Chie's husband, Keiichi, has been spying on them for a while. Nobuhiko is cheating with Chie Masaki, a pregnant woman. The house itself has new occupants, a couple named Nobuhiko and Keiko Haida. Although he gives the location, he warns the two women not to go into the house. Haruka decides to retake the case and visits Michiko, who agrees to perform a séance and ask Tetsuya's ghost. A year later, Odajima pursues Haruka again to ask her if she knows the location of the cursed house. Yudai is abusive to Toshiki and frequently beats him up, attracting the attention of child protection agent Kimie Ariyasu. In 1994, Kiyomi and Yudai have changed their identities and are married with a five-year-old son, Toshiki.
That night, Michiko is haunted by Tetsuya's ghost. Tetsuya's mother, Michiko, tells her that both she and her son are spiritually aware. Meanwhile, Haruka attends the funeral of Tetsuya, the latter having died mysteriously. After the two did so, she blackmails Yudai into killing Mina by threatening to report the rape. Kiyomi lures her teacher, Noguchi, to have sex with Mina. She meets Mai, who leads her into the unknown. Yoshie follows a lead to find Mai and ends up in a night club. In the days after, Kiyomi snatches her rape photos before dating Yudai. The trio leave the house without finding Mai. Kiyomi encounters the woman in white and screams, but when Yudai catches up to her, she suddenly throws herself sexually into him, apparently possessed by the woman. While Yudai is raping Kiyomi, Yoshie takes photos to blackmail her from reporting the act. Upon reaching the house, it is revealed that Yoshie and Mai are luring Kiyomi to be raped by Yudai. The girls are joined by Yudai Katsuragi, a male student from a neighboring school. Kiyomi is invited by her newfound friends, Yoshie Minakami and Mai Hyodo, to go to the same house visited by Tetsuya.
Meanwhile, high school student Kiyomi Kawai transfers to a new school upon the urging of her abusive mother, Mina. After a visit to one particular house, however, a woman in white carrying a baby begins haunting him. Haruka's boyfriend, Tetsuya Fukazawa, is scouting for a potential house to move into upon marrying her.
