Someone has replaced the engagement ring Rei bought Sawa with Kosuke's ring. In the meantime, Detective Ichinose is suspicious of Rei and Shoko because they have never seriously tried searching for Kosuke so he begins to re-examine Kosuke's disappearance.
Sawa tells Rei a shocking story of her past - she thinks Kazami is the perpetrator of her abduction. In the meantime, someone sends Rei a photo that evokes memories of Kosuke.
