If given a choice between fighting a Kitsune, a creature known for its cunning and shape-shifting abilities, or a Succubus, a seductive demon that feeds on the life force of men, trained adventurers from Nexaria would go for the succubus. No, and it won't be because of some prejudiced ideas relating to succubi.
The plain and simple reason was that they didn't want to die a horrible death. Besides, dealing with the succubi was easier than dealing with a kitsune.
Another reason for going up against Succubi instead of Kitsune was that the half-fox creatures were known to be immortal or, in other words, ageless.
They could live for thousands and thousands of years without ever showing any signs of growth. Forget about the vampires living in a forest and going to high school all to collect graduation caps; the Kitsunes had all that and more even before vampires were a thing.
