In this world.. There are demons..and humans, all of them lived peacefully before until humans started turning against them and getting rid of them with no hesitation, the only demon left was michikatsu..

until he met you...you both grew close, until he said

"I know you think you can run.. Your scared to believe I'm the one.. But I can't let you go.. I'd let the world burn.. I'd let the world burn for you."
