Lia de Beaumont

Lia de Beaumont (リア·ド·ボーモン, Ria do Bōmon) was D'Eon's older sister, who was killed under mysterious circumstances. Despite flashbacks of her being a caring and considerate young woman, who was well loved by the nobles and the royals, the spirit that possesses D'Eon is full of great anger, sorrow, and the desire to exact revenge.
