Azazel seems to view himself as a story writer or narrator
as over the eons of his existence, he caused numerous events amongst humanity. It was he who orchestrated the caravan assault that killed Favaro's father and ruined Kaiser's family. He was utterly amused to discover how history was coming back to bite him when the two bounty hunters confronted him in the royal palace, forsaking his mission to capture Amira to play with them some more and see if the story would satiate his twisted appetite.
Ultimately, however, Azazel views humans as nothing more than insects. This disdain is shown to extend to nearly all of his fellow demons as he constantly ridiculed Cerberus and did not even blink when he discovered Pazuzu was dead, simply calling his henchman a useless good-for-nothing. The only person he seemed to show any respect for was his boss and brother, Lucifer, and he was utterly outraged to discover Beelzebub was scheming against him.
In Virgin Soul, his personality has changed drastically. While he still disdains humans, he only targets those who harm demons, as his current goal is to protect and help his people. He is willing to throw himself into deadly situations for the sake of his comrades, and is deeply saddened when faced with their deaths. He even saves Nina when she is attacked by the knights, despite her failed attempt to catch him just moments before. He also cares greatly for Mugaro, whom he rescued from slavery two years ago.
Azazel is a tall handsome man
with pale skin, tight black leather clothing, and white hair. Being a fallen angel, he carries two sets of black wings on his back: one small pair and one large pair. His right arm is completely black and demonic, most likely a replacement for his original one and his left hand is regular. Two
small horns crown his head while a pair of curving horns extend from just above his ears to guard his cheeks and neck. Just under his left eye is a pair of small tattoos resembling tear stains.
He loses both of his curving horns after being attacked with Jeanne d'Arc's Maltet. Although one the horns is only partially destroyed by the explosion, the rest of it is gone by the beginning of Virgin Soul.
As the Rag Demon, he hides his identity by wrapping his body in bandage-like cloth and donning a tattered black cloak.
