During Reiko's confrontation against Kusano and Hikawa, she splits her being into two seperate entities. As her body runs through the city, causing mass hysteria, a smaller portion kills Maesawa from the inside. After shifting her internal attack to Hikawa, Kusano begins attacking her body as well. Distracted from the portion of Reiko's body inside Hikawa, Kusano is struck and killed by Reiko's remaing body. It's revealed when Reiko returns home that her child was taken by the detective.
