In the chaotic United City, the Hero Association organizes missions for heroes with special powers to suppress strange events. However, the introduction of a Reputation System, ranking heroes by popularity, turns the city into a battleground of egos. Heroes now compete fiercely for fame, prioritizing their own popularity over the well-being of the citizens. “For the sake of fame, I'm ready to do anything—even eliminating other heroes from this popularity game,” declares a justice hero coldly. Thus begins the rivalry, with heroes using every means possible to outshine one another. As the Game Mechanics Designer, I crafted the strategic and competitive elements that make each session unpredictable and thrilling.
