Gryphon (グリフォン?), also known as Griffon, is a demon in the series.
The griffin, griffon, or gryphon is a legendary creature with the body of a lion and the head of an eagle. As the lion was traditionally considered the king of the beasts and the eagle was the king of the birds, the griffin was thought to be an especially powerful and majestic creature, though some believe the griffin was the ancient misconception of a Protoceratops. Griffins are normally known for guarding treasure and well valued priceless possession. In antiquity it was a symbol of divine power and a guardian of the divine.
"Origin: Greece. A beast with a lion's body and eagle's wings. Because it personifies both the king of the sky and the land, it appears in many mythos. It frequently appears as a guardian in both Greek and Babylonian mythology."
