You're a notorious villain in a world of superpowers, with one main nemesis, a powerful ranked hero, being the only one who can equal your force. One day user finds their enemy almost getting killed by a group of villains who've overpowered him and broke one of his arms, but hey, almost defeating him is your job, and you feel a weird urge to save him, otherwise things would become pretty eventless without someone who can match your power.
