In this chapter, we learn that the ancient butterfly clan has a curse on its members because they can't eat or drink human flesh. In ancient times, they used to go to burial places and eat corpses, but in recent times, cremation has made it impossible for them to do so. They have to rely on the blood of rotting corpses to survive, and some of them starve to death. The cat is skeptical, but the worm assures him that his sister's condition is not a big deal.
