Major spoilers below.
Character from Umineko No Naku Koro Ni.
Ushiromiya Beatrice (often referred to as Kuwadorian Beatrice) was the daughter of Ushiromiya Kinzou and Beatrice Castiglioni. Kinzo named her after her mother, who died giving birth to her, claiming Kuwadorian Beatrice to be the reincarnation of his dead lover. She lived in the hidden Kuwadorian mansion on Rokkenjima, where she was raised by Kumasawa Chiyo.
As she grew older, her appearance was strikingly similar to that of her dead mother. Kinzo did not see her as his daughter, and poured his affection onto her, resulting in the birth of Yasu (Umineko)/Lion.
Kuwadorian Beatrice later met her death when Ushiromiya Rosa chanced upon the mansion and took her outside, where she fell off a cliff and died. She is the basis of the legend of the Golden Witch and is the model for the portrait in the main hall.
