Spiral (らせん, Rasen) is a 1998 Japanese supernatural horror film and a sequel to Ring (1998).

Andō soon learns of a mysterious cursed videotape, haunted by the spirit of a murdered young woman.

Despondent over the death of his own child, and believing that he is being guided by his rival's ghost, Andō decides to see the video for himself.

With the help of Takayama's student, Mai Takano, Andō discovers more about Ryūji's past and the mysterious young woman, Sadako Yamamura.

Searching for the truth about why Ryūji and Yōichi died from the virus while Reiko did not lead him to her boss, Yoshino.

Reiko believed creating a copy would break the curse, but Yōichi died 1 week after watching the tape, just like his father had.

When Andō tells Mai Takano what he has done, she is shocked and cannot understand why, since she felt from the start that it was the video that killed Takayama and his family.

He starts to feel that the story was just a myth and he is relieved when Mai turns up, but is shocked to find out that she has been found dead, having given birth with no sign of a baby.

Andō goes back to work, sees "Mai" there, and finds out that she is no other than Sadako Yamamura, reborn and claiming to be "perfectly dual-gendered".
