Aquila

Past Timeline
Aquila was born from an elf mother and a demon father. Aquila had a twin sister named Camilla. In the final war between humans and demons, her father removes his life token (a sign of great-demons) and sacrifices himself to help Aquila. Aquila then lead the army against purebred demons with an alliance of humans and mixed-blooded demons like herself. Camilla ends up betraying her sister and signs a contract with the other purebred demons but Aquila eventually defeats her. Aquila wins the last war but loses many of her friends and allies which make her feel very guilty.

It seems that her father may have been a demon lord so he sacrificed himself because he was going to be forced to fight against Aquila in the final war (Aquila is a half-demon while her father was a full-demon) the war was going to determine if full-demons were going to execute all humans and mixed-blooded demons.
