La Signora's death made a huge impact to the Fatui: some remaining members swore revenge against the Raiden Shogun while some returned back to Snezhnaya in hopes of waiting for a successor Harbinger replacing her position. Dottore did some investigating and learned that Signiora had a daughter who she had never acknowledged to anyone. His new objective is to track down the daughter and convince her to join the Fatui Organization so that she can carry on her mother's legacy. Will the good and innocent Y/n accept her fate and turn wicked herself, though?
