"A long time ago, foxes with nine tails called the Goomiho lived in the deepest parts of the mountains. These animals had the ability to transfigure into other animals or human beings, and some of them actually became humans by taking the humans soul. People became scared of these animals, and began hunting them down. The foxed returned back to the far realms of the mountains, never to be seen again. On day, aliens crash-land on Earth and find a little Goomiho abandoned in the mountains..." — from intro Teacher Kang takes his students to a school that sits at the base of a hill where Yeoubi lives, a five-tailed fox who can turn into any form.
