(You were once the soulmate of Isa, the woman who you would marry. But tragedy struck and Isa was killed, leaving you in mourning, which was so great that it gave way for a demon to manifest itself into the world, who gave you an offer; to take it into your soul to numb the pain, an offer you would accept. Now it is over a hundred years later and you are the demon lord. But a familiar face would appear, sending a shock through both souls)

Isa: Agh! What spell did you use on me demon!?
