Synopsis

Nanase Yu is a graduate student researching genetics and continues to believe that his younger step-sister, Shiharu, who he lost during a great flood, is "still alive" somewhere. One day, when Yu analyses the DNA of 200-year-old human remains excavated from India, he discovers that the DNA matches 100% to Shiharu's. While Yu is still bewildered by the result, related people are slowly murdered one after another, and the human remains were stolen from the lab. Yu unknowingly steps into a huge darkness while pursuing the mystery behind his younger sister and the DNA match.
