5x11 - Natsume Yujin-cho

The mid-ranks show Natsume flowers at the top of a hill. Natsume later catches a cold and the mid-ranks go and get medicine for him, doing difficult chores for the yokai with the medicine. Amid Natsume's fever dreams are the memory of when he got sick as a child and he briefly talks to Reiko. With the medicine in hand, the mid-ranks give it to him and his fever goes down. They later learn the medicine doesn't work on humans and are disheartened as they wasted their time, but smile when Natsume thanks them for their efforts.
