Episode title: Ancient City Insurrection (4)
As Tatsuya is researching the Traditionalist bases in Kyoto under Minoru's guidance, he meets the owner of a restaurant, who is also a Traditionalist, on the way to Kiyomizu Temple. The shop owner shares that he is concerned about the current state of Nara's Traditionalist sects being absorbed by casters from the Continent and offers to share information with Tatsuya. Based on the restaurant owner's information, Tatsuya narrows down a place in Kyoto where the Traditionalists are hiding. He meets with Mayumi, who wants to find the culprit who killed Nakura, and Masaki, who happened to come across them during a battle against the Traditionalists, and heads to Arashiyama with them.
