Demonas

A noble knight who roams the battlefield, Altear Chernobog. Under the emperor's orders, she went to war to kill her companion and beloved Ain Estarot, the "Son of the Demon," and in the end she was killed by him.

"Ain, I'm sorry. I wanted to protect you as far as my hand could reach."

Just as she was about to break through the memory fragments and go to the underworld, she opened her eyes and saw her father, who had died years ago, standing before her?! Altear, who returned to her childhood as if it were a lie, thought to herself. "The is my only chance to save Ain, who has been oppressed by humans all his life."
