Voices drift in from outside the mansion. Someone must be reading to children by the roadside. Guest listens to the voice blankly in the dim bedroom.
Guest, are you awake? After a while, Halcyon returns. As usual, he sits on the edge of the large bed where Guest rests. This bed is now the Demon King's only castle.
