Gods & angels , Demon & Devils , and a soul collector named Grim Reaper are they co- exist? to maintain the balance between human and the 3 immortal Realm the God of Creator created a place which named HEAVEN the place where the soul is pure and waiting for the resurection,
NETHERWORL where the soul repenting their sin's for a 2nd chance. And a place that full of madness, pain, hatred and where the most disgusting people and sinner who commited such an unforgivable crime they will go straight down to the HELL,
but in order for the creator to make it more interesting God of Creator created a Species that is fulled of suprise HUMAN in order to maintain the balance the god of creator made such a rule that demon angel are the mutual enemy that they have been forbidden to go interfere at human's bussiness and the god of creator split the heaven in to two layer the 1st layer where the god of creator guarded by the leader of the angels called Augustine , Aug is the captain of all the angels and the other layer which is called secondary heaven which normal angels where lived and so called prophet and Priest.
The Creator knew that the Demons will soon break the rules and invade the realm of human so the creator said this is the last help i will provide to you all, i wont interfere in worldy matter or even if the heaven will go down its up to your destiny you have to make it up to your own use whatever method you want even if you impliment the rule of the jungle.
