The emotionless holy maiden was offered as a sacrifice to the Duke.

"――I am nothing more than a 'prayer doll.' Dolls have no emotions……" The saintess, offered as a sacrifice to the wicked and immoral duke, murmurs those words while gazing up at the barred window. The duke smiles with cruel delight and declares: "From now on, you shall eat three proper meals a day. Now that you have become mine, do not think you will be able to live as you did before." ――This is a story of a girl who has closed her heart due to unfortunate circumstances, and a man who seeks to restore her smile.
