The Lesser Irregular Returns From the Demon World

To the eyes of the world, Hiroto Domori is nothing more than an Irregular—someone born without even a shred of magical or spiritual power. Dismissed as a hopeless weakling in a society that measures worth by ability, he appears destined to live forever in the shadow of everyone around him. Yet appearances could not be more deceiving. Hidden beneath his unremarkable exterior lies a secret no one could ever suspect: Hiroto has only just returned from the demon world, where he forged a reputation as the most fearsome demon killer the world has ever known. The strength everyone believes he lacks surpasses anything they could imagine. Now an unrivaled enemy has emerged—a threat so overwhelming that nothing seems capable of stopping it—and it has set its sights on innocent lives. As defenseless people fall victim to this unstoppable menace, the "weakling" Irregular must once again step out of the shadows. What unfolds is the ultimate collision: the underestimated lesser against the strongest of them all.
