Five

Aleicae ends his life as a human and, much to his displeasure, is born into an angel. But little did he know, his new life wasn't going to be heavenly choirs and golden halos, no it was bloody battles and a fight to save all of humanity.
As he's put through a whole new level of training, pushing both his mental and physical strength another army is churning in hell, and it's strong enough to push the entire world into apocalyptic chaos lead by Adrian, one of the most powerful demon to ever have been created.
Bloody battle after bloody battle passes and slowly the fate of life dwindles down to the shoulders of twenty two of the most powerful demons and angels, but the main question is who will win and what state the earth will be in after the death of so many angels and demons, and are we all actually safe?
