Keepers of the Balance
These beings come in all different forms. A lot of people suspect that they are of fairy origin, others say they’re Demons, but no one knows for sure. The Yokai themselves sure don’t tell. They quite like the mystery about them.
They have animal forms, but only ‘pure’ animal form, so people know they aren’t Werebeasts (or are they? :P). These animal forms vary. Some are foxes, other birds. There are raccoons, badgers, and even snakes. They also have human forms, and a bit of special powers.
They hail from the area of Nihon, which is where most of them still are, but a few, out of curiosity or some other reason, travel the world, telling stories of their home, what they have discovered, or just old legends.
