In this chapter, we learn that the school doctor is a demon spirit, and that he has come to investigate a dog spirit. The school doctor tells us that the dog spirit is a member of the body that night, but that he is also a person who is under suspicion for endangering public safety. He explains that the authorities of abilities are an institution that cannot be publicly made public, since they are "special" and cannot be used by the general public. The authority of abilities, he says, is a way to ensure that "ordinary people" do not suffer from the effects of these powers. He says that the current level of his ability is "practically harmless" and that if he were to "lick" the bone of the dog, his life would not be in danger. He tells the school doctors that if they follow him, their lives will be spared. He asks them to wear a collar so that they will not be harmed. He also asks them if they would like to become his servant. They refuse, saying that it is not their place to do so. He reminds them that the chief is there to help them, and he asks if they need to sign a special contract. They say that they do not need a special paper, since the environment is "relatively relaxed"
