A tengu is an Asian goblin or Demon who acts as a vampire, poltergeist, and trickster.
Descriptions of the tengu date to the eighth century. The Demon appears in the shape of a man with wings and long, sharp nails on his hands and toes. His nose is either a crow’s beak or red and round, and its size indicates the Demon’s strength. Sometimes, he carries a fan or a stick. The tengu is especially known for kidnapping people in remote, mountainous areas. He is fond of stealing children. Possession by a tengu is not necessarily diabolical. The possessed acquire supernormal skills and knowledge during their occupation by the spirit.
