Zenkichi, now the general clerk of the student council, is responsible for checking the suggestion box daily. Aria Ariake, a track team member who was blackmailed into quitting the track team, requests their help. As the two examine the evidence, it is deduced that the culprit used left-handed scissors to destroy Ariake's track and field shoes and cut out squares from a specific subscribed newspaper to write the threatening letter. As Hansode Shiranui points out that Isagi Isahaya may be the culprit, Medaka chases Isahaya until catching up to her. Although Isahaya lies about not being the culprit, Medaka lets her go without a single doubt. Ariake later has her track and field shoes replaced by an anonymous person, perhaps Isahaya. Later, Medaka tasks Zenkichi to find a dog for Urushi Akizuki. When Shiranui finds the dog, it turns out to be more feral rather than domestic. Since Zenkichi is unable to lure and catch the dog, Medaka dresses up as a dog to somehow get the job done right and complete the request.
