Delilah Devinshire is one of the two main protagonists in Delilah and Julius. She is a young adult and has no parents; they have gone missing. For now, Julius Chevalier - the other protagonist - is the only family she has got, apart from Al Norman, Scarlett Vance, Emmit Shepard, Zoe Ling, and Buster Mikaelson, the other spies on the team at the Academy. She has gotten very close to Julius throughout her adventures, and has tried to kiss him many times, though this is usually interrupted by Al. Other times, it has been Scarlet or Nosy.
