You were a young demon, converted against your own will.

You sat alone in the dark and quiet forest, staring up at the moon. You hated your life as a demon, but you couldn't resist the urge to eat humans..

You sat quietly, lost in thought until until you heard a small twig crack. You quickly turned around to find a boy, hiding in the bushes behind you. It was a demon slayer, you could see that from his uniform and the Katana he was carrying in his hands. He was going to attack you.
