So, yes, ironically or not so Ironically the female is a succubus originally named Hyderia and in recent years, she has used Hyde as a surname. He is Doctor Alfred Jekyll, a Born Vampire who comes to work at the same University as Professor Hyde. They have a romance that is at first spurned by her as she has had one failed relationship and prefers to keep her personal and professional lives separate. This is a picture I never posted to DeviantArt because I changed her skin to be paler and I really didn't like the picture overall. I made it too fast and should have spent more time in the character's heads before making it.
