SUMMARY
He was the crown prince of the shadow realm and the lord of wrath, Azrael. All creatures, demons, mortals, even angels feared him. However, everything changed after he went for a secret mission in the mortal realm in order to expand his seven sins power.
Hiding his identity among the mortals, the vampires were attracted by his royal blood. The mortals were either jealous or admired his abilities. The angels were curious about him. The demons wanted to kill him and take over his power.
Little did he know, he had another hidden power sealed inside of him. Something terrifying that could turn him either into the ruler of the three realms or an evil that could destroy all beings.
