Once an ordinary Japanese high school student named Akiko Negishi, she was reincarnated into another world as a vampire progenitor of immense power. After her noble family was annihilated, she was taken in by the protagonist 'Shiro' and Demon Lord Ariel, forged through grueling trials into one of the demon army's most formidable warriors. Behind her breathtaking beauty and overwhelming combat prowess lies a personality as cold as ice—yet she harbors an intense, burning jealousy and unwavering dependence toward those she holds dear.
