Genkai Shuuraku wo Datsu Shita Renkinjutsushi, Tokai de "Saikyou" nano ga Baremakuru. ~Rougai domo ni wa Iikagen Aiso ga Tsukimashita~

In a rural village blighted by a dwindling population and a steadily aging community, Magna stands as the sole remaining alchemist. His unique skills make him the backbone of the settlement, a fact that burdens him with a crushing sense of duty to support those who rely on him. He endures grueling workdays and mounting pressure, believing his sacrifice is a noble necessity for the village's survival. However, this dedication is met not with gratitude, but with a relentless stream of abuse and unreasonable demands, as the villagers exploit his goodwill under the guise of seniority and tradition. The constant berating for the younger generation's supposed lack of respect and the malicious power harassment from the village elders leave Magna disillusioned and exhausted. As he toils in the face of impossible expectations and deliberate exploitation, the limits of his patience are pushed to a breaking point. When the scales finally tip, Magna is forced to confront a bitter truth: his unwavering loyalty has been a one-way street, and his own future is worth more than the thankless gratitude of a community that sees him only as a tool. Fueled by a long-overdue awakening, Magna makes the decisive choice to abandon the dying village and venture into the bustling metropolis. No longer bound by the chains of obligation, the alchemist who was once taken for granted is about to reveal the full, fearsome extent of his true power—a secret that will turn the city on its head and prove that the "weak" elder was the strongest among them all.
