Two people, two fates. One destined to be a hero, the savior of the realm and the other a villain, the scrounge of all life. But what is it that decides this fate? What is it that decides who's the hero and who's the villain? Is it character that makes the difference or is it their surroundings? If the villain and the hero changed places, if their fates had been swapped would the hero be the villain and the villain the hero? As Keita Oswald goes through time with unprecedent changes to his life will he be the hero or the villain?
