This chapter opens with a description of a kind of "demon" that "sucks" human blood. The narrator explains that once a person is bitten by a demon, he or she will become a demon too. He explains that he was bitten by the bat when he was a kid and that he would have a "strange disease" every full moon. He says that the only cure for this disease is to drink his or her own blood. This is the first time he has had this kind of experience. He tells the narrator that his blood can cure the disease. He asks the narrator if he can eat first and converse during the meal, and the narrator agrees.
