Draghoul

"[INDISCERNABLE ANGRY GRUNTS AND GROWLS]"

- Draghoul's catchphrase, ideals and views, on life, the universe and everything Draghoul (ドラオル, Doraoru) is a mindless, ferocious, skinless Demon who follows the orders of Helel and subsequently his son, Balor, acting like a well-trained pet, as opposed to a proper soldier, having the same intelligence as a wild animal. Due to his distinct look, being a large dragonic skeleton, he is often referred to as the Skeleton Dragon (骸骨竜, Gaikotsuryū). Draghoul is known to be one of the most powerful members of the Fallen Army, second only to its three main leaders, Helel, Balor and Volant, primarily due to his enormous size and destructive power.

Trivia
