I Was so Bored That I Created the Hero

This is a story about an evil and powerful demon king playing tricks on a helpless and weak hero... It is also a story about two dead sisters fighting for favor. Is it a loss of morality or a distortion of human nature when a middle-aged boy beats me up online? All the answers lie in the fact that I was too bored as the Demon King, so I created the Hero.
