The Polished Soul

The Polished Soul Yuma is a factory worker crushed by poverty, loss, and quiet despair. His life revolves around endless labor meant only to delay his mother’s inevitable death. When she passes away, and the woman he loves abandons him for a wealthier man, Yuma reaches his breaking point—only to awaken something far more dangerous. At an ancient shrine, time itself freezes, and Yuma is chosen by Kaigen, a shattered sentient sword born from suffering. The blade does not grant strength freely—it feeds on pain, rage, and broken souls, forging its wielder through psychological torment rather than physical training. Yuma is torn from his world and cast into a vast, untamed land where monsters roam and civilizations prey upon the weak. There, he discovers the terrifying truth behind Kaigen’s power: every enemy he kills grants him not only strength, but fragments of their memories, skills, and language. Their sins become fuel. Their suffering becomes his burden. As Yuma struggles to survive, he encounters Luna, an elven girl forced into betrayal to protect her younger sister. By saving them, Yuma begins to walk a dangerous line—protector to the innocent, executioner to the cruel. Yet Kaigen warns him: power drawn from suffering must be tempered, or it will consume him entirely. In a world where corruption breeds monsters and mercy is seen as weakness, Yuma must decide what kind of existence he will forge— a hero shaped by pain… or a weapon that has forgotten why it was ever human.
