Hiyori's first day at high school becomes a nightmare for her when Yato possesses her body, after she unintentionally slips out of it upon falling asleep. He uses Hiyori's body to his advantage by doing all sorts of embarrassing and over-the-top things to spread word of his services to the other students, with Kofuku joining in on the fun. Yukine tries to get Tenjin and Mayu to help put a stop to Yato's antics, but they too end up getting distracted. As Hiyori struggles to make Yato return her body, she and Yukine spot a perverted student, who sneaked a camera into the girl's changing rooms, and discover he has been possessed by a phantom. When the student attempts to jump out of the window upon being discovered, Yato manages to rescue him and subdue the phantom, but ends up breaking his (Hiyori's) shoulder in the process. As such, Yato is caught and given an appropriate punishment whilst Hiyori begins her next day of school with a bizarre reputation.
