The shining Möbius Mark was two small snakes biting each other's tails. They formed an '8' ring and slowly moved in this shape, looking as though they were alive. As they moved, the scales on their bodies reflected all kinds of different colors in a pattern, making the entire Möbius Mark look like a rainbow.
If you looked closely, you would find that the two small snakes actually looked a little different. One of the small snakes had a pair of slightly sharp horns on its forehead, and the other snake had a pair of immature white wings on its back. This meant that they respectively represented the Ouroboros Mark of the demons and the Ouroboros Mark of the angels.
It was the first time Roy had seen the mark manifested. He looked at it obsessively and could not help but reach out to grab it, but his palm passed through the mark and touched nothing.
