The next morning, the police confirm that Detective Terada was murdered by a woman named "Steel Lady Nanase" . The police also confirm that the crime was committed by a police officer named "Detective Terada" , who was hit in the head by a cinder block thrown by the steel lady. In the meantime, the monster continues to grow, and the police are unable to find any evidence of her involvement in the crime. The monster's presence in the world will make it impossible for the police to solve the mystery of the murder, so they will have to invent a way to defeat the monster. The only way to do this, they decide, is to create a "rational fiction" that convinces the public that the monster is real and that she is responsible for the murder. If they can't do that, they'll never be able to create an "imagination monster" like the one in the novel.
