Angelica Rapha Redgrave is the daughter of Duke Redgrave and the former fiancé of Prince Julius Rapha Holfort. In the original otome game, Angelica was the first antagonist. Angelica originally was supposed to be very hot-headed which would be her eventual downfall but because of Marie, we get to see more of who she is.
