In Japan foxes are consider clever and cunning. When I first heard the expression, "she is a fox/ foxey" I thought the person didn't like the girl! And the 9 tailed fox Youkai (kyubi) supposedly have come from China after eating an emperor posing as his beautiful wife. Also as you know, Seimei's mother was said to have been a Kitsune. There are some very good Kabuki plays based on it. And don't forget, Kurama from YuyuHakusho is a kitsune youkai, too. Wow come to think of it, there are lots of kitsune based mystical legends that I took for granted...
