"Bēruaroken" (ベールアロケン) is the fifth boss from the game Super Ghouls 'n Ghosts, a demon that appears to be made of ice and bones. When spotted in the end of the stage, this boss will detach its lower half and start flying around, attacking Arthur by throwing his arms like boomerangs. He also releases projectiles from his mouth that don't cause damage, but temporarily freeze Arthur, leaving him defenseless until he returns to normal or is hit. This cold demon can only be damaged when hit on the head.
