Yoshimori and Yurina become aware of a black ghost cat on the shoulder of Kurosu, their literature teacher. Meanwhile, Masamori is now promoted as the seventh seat of the Junininkai, the elite executive committee of the Urakai, thought the other seats already despise him. After having informed Tokine and Gen of the situation, Yoshimori interrogates Kurosu of any association with a cat. Kurosu responds by saying that the cat had grown fond of him when he used to spend time reading outside. Matsudo tells Shigemori that the prototype human skin suit serves as an armor for the ayakashi, enabling them to be active during the day. The setback is that the skin is transient in material and restrictive in power, despite the fact that there are some ayakashi desiring to become human. Kurosu mourns for the black cat, after finding out that it had died in a car accident, allowing it to finally rest in peace.
