Sadako Yamamura

This is a list of Ring characters.

Kazuyuki Asakawa is the lead character in Koji Suzuki's novel Ring, published in 1991. He is married to Shizu Asakawa and they have a one-year-old daughter named Yoko. His best friend is Ryuji Takayama, an alleged rapist. After his wife's niece Tomoko dies and he comes across another boy who died on the same day on his motorbike, Asakawa tries to find out why which then links him to the cursed videotape. After watching it, he is left with just seven days to figure out how to break the curse.

Other versions of Kazuyuki Asakawa are two other female characters, Rachel Keller from The Ring and Sun-joo from The Ring Virus. These two characters are more adaptions of Reiko Asakawa, than Kazuyuki Asakawa.
