Rikka finds a stray cat, which she claims is a chimera, though cannot keep it in her apartment due to Toka's allergy to cats and Yuta refuses to take it in himself. Meanwhile, Yuta finds himself nervous around the class president, Shinka Nibutani, which becomes more awkward when Rikka shows up. Later, another student named Kumin Tsuyuri inquires about the cat they found, as she had been looking for her own who ran away. Both Yuta and Kumin go to Rikka's apartment, filled with all sorts of oddities, though the cat turns out not to be Kumin's. After Toka swiftly punishes Rikka for bringing the cat in, she asks Yuta to get rid of it, threatening to expose Yuta's chunibyo behavior if he refuses. As Rikka runs off with the cat, Yuta runs off with the audio evidence and they both try to escape Toka, but are eventually caught. Afterwards, Yūta agrees to take in the cat.
