Kidnapped by the Demon King and imprisoned in his castle, Princess Syalis is...bored.

This time it's the princess who gets shrunk to the size of a child, and with dire consequences...instigated by her, naturally. The mystery of why the Ten Guardians number only nine individuals is investigated...with mixed results. The search for a spy in the castle ends in...confusion. But at least the story of Demon Cleric's transformation into a gentler, kinder demon is clarified. Plus, hypnosis, hot pot, and Midnight's hound!
