The Divination

In order for Demons and Angels to live in harmony on earth, they need the four.
One that is purely good with a heart full of love, turned into a Demon.
One that is purely evil with a heart full of hate, turned into a Angel.
One that is both equally good and bad, turned into a half Angel and half Demon.
And one that is neither good, nor evil, and is to become an immortal who is both a server of the good and the bad.
It is believed that it will balance out the differences of Demons and Angels, but will it?
