She retains the face of the human she merged with, which is surrounded by a set of horns with a large crest at the top. Her head sits on top of a long, dark neck which is actually a second head, with a large mouth with sharp eyes and a second set of eyes.
This demon is amongst the many demons who gathered at the Black Sabbath held by Ryo Asuka. After Amon's mind is absorbed into that of Akira Fudo's, she weeps at his passing, to which Akira insults her. She is later killed when Akira goes on his bloodthirsty rampage against the demons.
- She is often mistaken for Wagreb, another Sabbath demon with a similar design.
- Interestingly enough, during the OVA Devilman: The Birth, which covers the events of the first volume of the original manga, that serie's version of Wagreb replaced the horned demoness altogether, being the character who laments Amon's possession at the hands of Akira.
- In the manga Devilman Grimoire, the Wagreb of that series has the Horned Demoness's crest and horns on her head.
