Anges, a servant of a Count's family, did not remember her childhood and was oppressed for her "lack of emotions." Then one day, she was given in marriage to Gilbead Deadrix, who was feared as the "Duke of Death." This happened because the Count sent Anges to the Duke's house instead of his daughter.

Contrary to the terrifying rumors, Anges gradually recovered her emotions under the care of the gentle duke. As her memories began to return, she realized that she had hidden abilities.
