Raijuu, meaning "thunder animal/beast," is a creature from Japanese lore said to be composed of lightning and may take the shape of a cat, fox, weasel, white wolf, blue wolf and even a wolf wrapped in lightning. It may also fly about as a ball of lightning with a cry that sounds like thunder. Raijuu is the companion of the thunder god Raijin. While the beast is generally calm and harmless, during thunderstorms it becomes agitated and leaps about in trees, fields and even buildings.
