Demonas

A knight named Altear Chernobog was ordered by the emperor to fight against her companion and lover, Ain Estarot, known as the "Son of the Demon." She ended up being killed by him, saying, "I wanted to protect you as far as my hand could reach." As she was about to move on from her fragmented memories to the afterlife, she awoke to see her long-deceased father. Altear finds herself back in her childhood, considering it a second chance to save Ain, who has endured persecution from humans throughout his life.
