Five years have passed since Kuryu Kohei's transfer from Tokyo to Ishigaki, and then to Sapporo. He ends up in a small town of Nijigaura in Yamaguchi Prefecture. There, he investigates a murder case involving a local enterprise, Kamoi Group, and the people related to it. Everyone in town thinks he's innocent except Kuryu, whose unorthodox investigation methods perplex not only the townspeople, but his colleagues as well.
