Kuzu Inou "Ondo wo Kaeru Mono" no Ore ga Musou suru made

Two decades ago, individuals known as Talent Users suddenly emerged, wielding extraordinary abilities that shattered the global balance of power. This upheaval ignited a devastating decade-long conflict known as the World Talent Great War. When the fighting finally ceased, international treaties and massive geographical shifts forced the world map to be entirely redrawn. Society was fundamentally restructured, transforming from a world where Talents simply existed into one entirely dominated and ruled by them. In this new era, protagonist Atsushi Serizawa awakens to his own ability, harboring a lifelong dream of becoming a hero. However, his aspirations are immediately crushed by the harsh reality of the government's classification system. His power is officially evaluated as "One Who Changes Temperature," earning him a dismal S-Level 1 ranking—the absolute lowest tier on the five-level scale. In a society that reveres overwhelming strength, this designation brands his ability as worthless trash in the eyes of the nation, leaving him at the very bottom of a world built for the powerful.
