The Piru is a minor evil spirit or Demon in Finnish mythology. In folklore the Piru often features as a nasty spirit of the forest with which a wise-aleck either wins or loses a battle of wits, giving or receiving a forfeit in return. The Devil is often referred to as Pääpiru, literally "Headpiru" means Bosspiru in that case.
