Region of origin: Japan
One of the sub-groups of yokai of animals believed to increase in intelligence and magic power as they age, it is believed when a fox turns 100 years old it grows a second tail and gains new powers such as shape-shifting or the ability to create illusions. This continues to increase every hundred years up until it has nine tails and their fur has turned from red to gold or white. The kitstune are broadly divided into two categories, the zenko kitsune are considered benevolent and who act as messengers for the Shinto deity Inari, whereas the yako kitsune are more malicious pranksters, but both groups tend to use their magic to the end of punishing people who have done something to deserve it and respect those who show them kindness. Among their more common tricks, they can possess people and cause them to behave erratically or destructively, or they may turn into people their victim knows to sow confusion, or someone the person will find attractive to seduce them away from their families. The latter can be short-term, but there are stories where it results in an actual long-term relationship and marriage, occasionally producing half-human offspring who possess some of their kitsune parent’s magical abilities. Kitsunebi, or “fox-fire,” is a form of ignis fatuui that is believed to be magical lanterns the kitsune can summon and will use in their wedding processions.
