The third girl, who has been staying at the school for a long time, tells the others that she has been away for a few days, and now she has become the third girl. She tells them that she had told her family to move to the school, and that she would have become the fourth girl if she had not stayed. She says that the pact between her and the other girls could not be broken off, because the pact also invested in the school and the demonic realm too. The other girls are making excuses for her, she says, because she is reluctant to leave. She blames herself for being tired, and says that she is tired because she has given up on trying to analyze the cause of her fatigue
