Sayako walks into the classroom and finds Kaori Hasegawa, Mitsuhito Amagasaki and Seita Kanemoto. They talk for a while and Kaori, now angered, runs away. Sayako and the rest of the group goes to look for her after a while. They find Kaori on the other side of the classroom, but they are separated by a hole, so they talk for a while. They find an old generator and manage to turn it on. Then Sayako and the others go around, and they see Kaori walk into the Science Lab and Seita goes to follow, but Sayako stops him and goes by herself. She finds that the anatomical model moved from its spot, but doesn't attack her, so she leaves. Outside the classroom, Sayako and the others talk when suddenly the anatomical model charges out and grabs Mitsuhito, dropping him and itself down the hole. Sayako and Seita calm down and continue on their way. They go and talk with Kaori once again and she gives them the iron lever.

Sayako and Seita find the classroom with a body of Shiho Hasegawa, Kaori's sister. She tells them to tell Kaori to live her life and forget about her. She also gives Sayako her yellow ribbon. They both then went into the Principal's Office and see that there is a huge statue of a gogatsu ningyo inside, it suddenly moves and tries to attack them. Sayako stays behind to protect Seita, while the latter is told to run away. After Sayako has given him enough time to run away, she comes back but finds out that Seita wasn't running and was worried for her instead. The monster then appears again, but this time Sayako manages to use some kind of power to make it disappear.

After that, they both finally meet up with Kaori and they all go to the Infirmary to get some rest. In there, Sayako tells Kaori about Shiho and asks if she wants her younger sister's ribbon back, but Kaori declines. Mitsuhito, now mad, walks into the Infirmary. He says that he will be able to escape if he kills them all, so he attacks them. Kaori tells Sayako to bring Seita and run away, so they do. They all hide inside one of the classrooms and Mitsuhito looks for them. They all escape one by one, but Seita gets caught in the outside. Before Mitsuhito manages to kill him, Sayako once again uses her mysterious powers to tear his hand off, then followed by his head, thus killing him. After that she faints. In her flashback, it is shows that she and Yoshiki became friends after his friends died in the cursed school. She taught him kendo and she seemed to start liking him. One day an evil spirit appeared to take Yoshiki away, but Sayako defended him and died.

Sayako then appears for the last time after Kaori and Seita gets caught by the anatomical model. She uses her new-found powers to make it disappear. After the group reaches the classroom, Sayako explains that she can't go with them as she is the new "host" of the school. Seita cries and Sayako gives him a charm, she ties Shiho's ribbon over his eyes, thus blindfolding him. After that Kaori and Seita leave. In the white world, Seita gets distracted by a fake Sayako's words to come with her and he looks back. Since the charm he wore didn't let him see the evil spirit, he was saved. In the end, Sayako cried that she doesn't want to hate the living, and turns into an evil spirit after she calls out for Yoshiki, using his nickname "Yoshi."
