Usually used in anime's and manga's, a kitsune is a mischievous creature, mainly using the form of a fox, with an ability to shapshift. Kitsunes can have multiple tails, apparantly.
In some anime's/manga's, they're cute little things in a chibi form that are so adorable and cute that you want to hug it forever, and in some cases they're voice can be so high and annoying you'd wanna shoot it.
They are demons, in a way, but keep in mind, this is a mythalogical creature, is only seen in anime, manga, and ur imagination.
