4x7 - Natsume Yujin-cho

Natsume is saved by Tanuma and the two escape from the banquet hall with the help of Natori, who was disguised as a youkai. Tanuma is drawn more into the world of the youkai and experiences it first-hand, which greatly worries Natsume. Blood marks are found all around the mansion and Natsume's fears come true when Tanuma is attacked by Omibashira, but is protected by a stone Natori gave him. After Natsume helps Natori seal Omibashira everyone is able to escape the previously sealed exits. Promising Tanuma that he'd tell him his complaints at school the next day, Natsume finally arrives back home.
