Rikka finds a stray cat, which she claims is a chimera, though cannot keep it in her apartment due to Touka's allergy to cats and Yuuta refuses to take it in himself. Meawhile, Yuuta 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 Yūta and Kumin go to Rikka's apartment, filled with all sorts of oddities, though the cat turns out not to be Kumin's. After Touka swiftly punishes Rikka for bringing the cat in, she asks Yuuta to get rid of it, threatening to expose Yuuta's chuunibyou behaviour if he refuses. As Rikka runs off with the cat, Yuuta runs off with the audio evidence and they both try to escape Touka, but are eventually caught. Afterwards, Yuuta agrees to take in the cat.
