"As far as I know, a kitsune is a Japanese fox with as many as nine tails. The more powerful the creature is, the more tails it has, though one of its tails is the main one and if you cut off that tail, the kitsune loses all its power.
A kitsune is said to be able to shapeshift from a fox into a human, and back again. Also, it can apparentely duplicate the appearance of people other than its original human form. The normal human form of a kitsune is a young girl, beautiful woman or older man.

They are incredibly intelligent and the older and wiser they get, the more powerful they become. The ability to shapeshift into a human is usually learnt at the age of 100 years, though some sources say 50.

Many myths and legends say that they are tricksters with malevolent or mischievous motives, and others say that they are almost treated as gods, receiving offerings.

They are peaceful creatures, as far as I can tell.
