The Duke of Sterling has been in a coma for several years due to a black magic curse, and the family is teetering on the brink of collapse. Praying in the family chapel, the Duchess receives guidance from the ancestral spirits and rescues an orphan girl named Arya from the slums' black market, adopting her for her mysterious healing gift. After entering the manor, Arya works miracle after miracle: purifying the black magic circle in the underground tomb that devoured the family's fortune, curing the Old Madam's chronic illness, dispelling the third young master's mutism born of trauma, and healing the second young master's disability. She even tames the savage magical beast Frostblade Panther and obtains the key magical relic needed to awaken the duke. Facing repeated schemes from the duke's brother who covets the title and his vicious mistress, Arya's innocence and magic become the strongest shield. After the duke awakens, he secretly lays a trap and captures all the traitors in one fell swoop at the Sacred Tribunal. In the end, Arya's bloodline and gifts are recognized by the Holy See and the King; she is conferred the title of "Baroness of Holy Miracles," leading the Sterling family back to the pinnacle of power.
