(My new book, The Astonishing Killer God, has started updating. Everyone is welcome to check it out! Please show your support~!) Perhaps Heaven was playing a cruel joke. If someone is destined from the moment of birth to become the demon king who destroys the world, what choice will they make? What truly separates good people from bad? Are bad people necessarily evil in everything they do? And do those so-called good people never do anything wrong? Perhaps fate cannot be changed. Perhaps the world is destined to be destroyed. But even if the world and its people perish together, a moving story will remain behind. Those who survive are destined to remember it and pass it down from generation to generation.
