A woman named Yuko Fuwa comes to the Narumi Agency to ask for help in looking for her lost cat Kinou (whose name means "yesterday" in English), and Shotaro agrees to take the case, much to Akiko's shock. Elsewhere, Ryu investigates a strange set of attacks, all linked with a strange hourglass symbol printed on the victim. After looking around Futo Hall, stopping at a poster of Saeko and Futo-kun, Shotaro resorts to making cat noises before Yuko joins in.
