Kitsune are trickster foxes from traditional Japanese folklore. They are a type of yōkai, a class of supernatural creatures with godlike powers, often equated to the English ghoul or demon. Kitsune are noted for their paranormal abilities, particularly metamorphosis. As they age, these abilities can become more powerful.
 
In Japanese mythology, there are said to be 13 types of kitsune, which correspond to different elements—celestial, wind, spirit, darkness, fire, earth, river, ocean, forest, mountain, thunder, sound, and time. Broadly, they can also be broken into two groups—zenko, or good, and nogitsune, or bad.
 
There are primarily two types of Kitsune: mischevious and good.
