In a quiet residential area in Setaya, Shinoda Sukiko (Naoko Hata) was attacked by unknown people and fell from the stairs.SSBC who arrived at the scene forcibly committing crimes in SSBC and Rintaro Mahara (Masaki Aiba) found that Shoko, who was sent to the hospital, had two red marks on her neck that looked like scalds, and her left foot shoes were not known where to go.Although the mobile search team ordered "please collect surveillance images", Igaki and Mingbo still approached the stairs, trying to speculate on their fall.At this time, Aoi Aoi (Nao Matsushita), who was searching for a lesson, rushed to the scene and quickly drove the two away.
