This book belongs to the growing constellation of works that began with Koji Suzuki's best-selling horror novel Ring, and is linked most directly to its sequel Loop.
Cram-school math instructor Seiji Kashiwa is a creation of the supercomputer LOOP, and the biological information implanted in him reflects the lives of Ryuji Takayama, who appeared in both Ring and Loop, and Kaoru Futami, who appeared in the latter volume; but due to a system error, portions of his memory have become lost. One day, student Rie Yoshina comes to him for advice regarding her friend Haruna Tajima, who inexplicably fell into a coma after seeing a female dogu figurine of the Jomon Period (ca. 12,000?300 BCE) depicting the release of a snake. It is a baffling story, but as he listens to Rie's account, Seiji senses intuitively that it is a message directed at him. As if guided by some unknown force, he begins going back over the events that took place in Ring. The reader learns about the conflicts between Shizuko Yamamura and her daughter Sadako, who were central to the events; about the early years of the ancient ascetic who gave Shizuko her special powers; and about the surprising secret of Ryuji Takayama's birth . . . In the process, Seiji becomes one with Ryuji, and begins filling in the missing pieces of his memory. At the same time, he comes to feel a connection with the unbroken tides of human passion and memory that have ebbed and flowed since time immemorial, and in turn, to understand why he has been given life in this world . . .
The original horror series has taken on elements of science fiction as it has developed; in this work it furthers its scope in space and time by reaching into Japan's ancient myths, ascetic traditions, and other folk and occult practices.
