Risa is a quiet, bookish person with a tendency towards romantic idealization. Nathaniel Golzine was her first (and only) love, but his identity as a mob heir was too much for her to deal with. Instead, she settled down in a more peaceful life, with a kind but bland husband. The unresolved feelings and mutual attraction between her and Nathaniel nevertheless resurface every time their paths cross, and their affair resulted in Ashley‘s birth.
But there is more to Risa than meets the eye. A fantastical creature has taken a liking to her and put her under its protection. Risa carries a unicorn blessing, making her immune to disease or corruption. When the dangerous vampire Gilles de Rais took an interest in her, Nathaniel had no choice but come to the rescue.
