Greol

Appearance
The bright red eyed monster, its body is of faint gray color, and it looks similar to gargoyles that show up normally in fantasy worlds. With wings that have its bones bare.

Personality
Arrogantly, he looked at humans only as food.

Abilities
An Archdevil that was sealed by a Cherubim. Can control even High Devils, and it is called the King of the Devil race.
