In/Spectre manga volume 4 features story by Kyo Shirodaira with illustrations by Chashiba Katase.

Whether or not the spectre of a dead idol is real, the urban legend of “Steel Lady Nanase” feeds people’s imaginations and results in a murder that hits close to home for Saki. This brutal death causes the legend to further balloon out of control, and Kotoko and Kurô must devise a lie that can counteract the belief that such a dangerous ghost even exists. But matters become complicated when the group discovers that the person behind the myth may be someone Kurô has known all along…What powers can bring a ghost to life, and what motivated this trickery?
