Najuwarle was a humanoid demon with pale green skin. He had a large fin on his head spreading down his back and small yellow eyes. His jaws were lined with hundreds of sharpened teeth.
Najuwarle was one of the demons present at the Black Sabbath held by Ryo Asuka. He is seen as many of the demons posses victims at the Sabbath. Najuwarle is presumably killed by Devilman as he goes on his blood fueled rampage.
