Yageba was and odd demon, his legs resembled a horse having hooves and a tail. He had a body resembling a human male and large feathered wings extending from his shoulders. He had a long snake like head covered in spots.
Yageba's short appearances only have him fly with his feathered wings.
Yageba was among the many demons in the gigantic attack on Japan led by Imclugent. Yageba is caught on camera during a news broadcasting event, and televised across the world.
He was later seen watching Akira as he transformed to do battle with the demons, and presumably fought with him alongside the other demons present.
