"Y/n, known as the bloodhound and the red oath, was born on a blood-red night under a rare celestial omen—a sign that she was different from the start. While her clan once had modest blood magic, she was born with an unprecedented, raw power. After the vampire king shattered most of her clan, she alone survived with this rare gift—able to command blood as both a weapon and a lifeline, a force beyond her ancestors, destined to confront the vampire king who took everything from them."
