Mitsuo Yoshioka, Managing Director of Yabuta Construction, has disappeared. The managing director's daughter, Mayu, who works in her secretary's office, searches for her father's whereabouts and arrives at Yamagiri Construction, which is the Yabuta Group's entertainment sex slave training facility. Mitsuo was also involved in training slaves for entertainment, but ironically, Mayu also became a candidate for sex slave, and Mitsuo, who tried to protect Mayu, became the target of the organization's purge.
