A second-year, Ariake-senpai requests the Student Council’s aid for solving the problem of a threat she found in her sports locker along with a ruined set of spikes. Medaka immediately deduces the culprit down to everything but their name from just the letter and the state of the shoes, and goes down to the sports field to catch the culprit. After being outrun by Medaka, Isahaya-senpai denies having touched Ariake’s spikes or making the note, but Medaka believes her immediately, dropping the matter. Feeling guilty, Isahaya takes Ariake’s trainers and replaces them with a brand-new set of spikes and an apology note.
When Zenkichi is asked to complete a request to find a lost puppy, he miserably fails after finding out the puppy had grown into a much bigger dog. Medaka helps him out, only for Shiranui to find out that while Medaka loves animals, animals don’t love her for some reason, with the dog fleeing from her and hiding behind Zenkichi.
