Reiko Nishihori, the daughter of copycat criminal Koya Nishihori and former host of the Seeker Roidmude, is to be released from prison. Go Shijima, who identified with Reiko due to their similar backgrounds, took the stand during the trial and testified in her favor, also deciding to support her after her release. He was eagerly waiting for this day to come. Go’s older sister Kiriko, now a wife and a mother, wishes for his happiness from the bottom of her heart.
However, on the night of Reiko’s release, a series of murders took place. The murder weapon seems to be woman’s hair. Reiko is shown on the camera feed taken from the murder scene. Shinnosuke Tomari, an officer of the Special Circumstances Team of the 1st Division of Investigations, marks Reiko as a suspect. Go, believing in Reiko’s innocence, aids her escape. Reiko, however, believes that “The child of a monster cannot escape the curse laid upon them” and leaves Go’s side. Go, at loss of any motivation, is met by an unlikely individual.
Is Reiko the culprit? Go, with his feelings for Reiko and the strength of an irreplaceable friendship, goes after the truth!
