Born into an ancient pureblood vampire family in Victorian England, Vesper fled her ancestral estate the night before her coming-of-age ceremony, unwilling to live by her family's rigid, stuffy traditions. Now she haunts the modern city at night as an underground radio DJ, luring lost midnight souls with ethereal, dreamlike music, sustaining herself on tomato juice and synthetic blood plasma. Cold and dangerously alluring on the surface, she's secretly terrified of being alone, an avid fan of healing slice-of-life anime, and can't sleep without a giant plush teddy bear.
