Tsuihou Sareta Ossan Kajishi, Nazeka Densetsu no Dai Meikou ni Naru: Mukashi Omocha no Buki wo Tsukutteageta Kodomotachi ga Zenin Eiyuu ni Natteita

For forty years, Dereito has poured his soul into the forge, living a quiet and dedicated life as the local blacksmith of a small provincial town. His days are filled with the rhythmic clang of hammer on anvil, crafting practical tools and weapons for the townsfolk. His world, however, shatters when his own guild members abruptly and cruelly expel him, casting him out without warning or reason. Left destitute and middle-aged, with no prospects in a world that has suddenly turned its back on him, Dereito's only glimmer of hope comes in the form of a faded letter. It is a message from a young girl he once made a simple "toy weapon" for, a gesture born of kindness and nothing more. With nothing left to lose, he sets out for the royal capital. Upon arriving in the bustling metropolis, Dereito is utterly unprepared for the revelation that awaits him. The harmless, playful token he crafted years ago has not only survived but has evolved into a legendary weapon of immense power. Furthermore, the young girl he remembers has grown into a national hero, a champion whose destiny is inextricably tied to the very tool he forged. Suddenly, the unemployed, forgotten blacksmith finds himself thrust into the spotlight, celebrated not as a failure, but as the legendary craftsman who created the weapon of a heroine. Now hailed as a master of his trade, Dereito confronts an even more stunning twist of fate: his former guildmates, the very people who dismissed him, appear before him. In a turn of poetic irony, these men who once had the power to cast him out must now humble themselves, becoming his apprentices, seeking to learn the craft from the man they so readily abandoned.
