Tenko is a type of kitsune found in Japanese folklore and mythology, believed to be the second-to-last stage that a good-aligned kitsune could evolve into.
Tenko have obtained a state of power sufficient to be seen as minor gods, they are also ranked the highest in all of kitsune society (despite Kuko having more magic than them).
While benevolent in nature a Tenko may also possess humans, when they do so it is to gift them with clairvoyance - allowing them to predict the future.
As with the Kuko and Kiko they are no longer physical beings and are considered pure spirits, thus can take any form they desire but tend to resemble beautiful human-like goddesses with some kitsune traits, usually they have four tails as well as golden, silver, or white fur.
