Thick fog wrapped around Fog City's dome like a shroud of sin, while inside the Alcarte Mansion, glasses clinked at a grand ball that concealed fangs and crimson eyes. Ella Vein glided through the crowd in a silk gown, a silver dagger hidden beneath her skirts gleaming coldly, the cheap scent of iris root powder in her upswept hair unable to mask the hatred in her eyes—she was the orphaned survivor of a fallen noble house, and a Hunter in disguise, with her sights set on the silver-haired Vampire prince Alcarte who lounged indolently on his velvet chair. Elegance was her armor, humility her mask. She had planned to use the ball to approach her enemy for revenge, but accidentally stumbled upon the fragile balance between vampires and humans, becoming entangled in the shadows of a mysterious "blood plague." When Camien's crimson eyes saw through her disguise yet extended an invitation to dance; when the plague disrupted her revenge plans, her sworn enemy unexpectedly became a temporary ally. She entered the vampire's lair with a Peachwood Stake concealed, yet fighting side by side in dark alleys, she discovered another hand behind her family's massacre. Wielding her Hunter's Silver Dagger while investigating the source of the blood plague, she faced betrayal and the collapse of her beliefs in the Forbidden Repository of the Guild. The Night Shadow Rose carried deadly thorns, and her silver dagger reflected the faint light of dawn. Walking the edge between light and darkness, how would Ella choose between vengeance and duty? As the Blood Moon hung in the sky and the gears of the Eternal Night Ritual began to turn, would her temporary alliance with the Vampire prince be enough to tear through Fog City's deepest conspiracy and welcome the true dawn?
