Yakudatazu Skill ni Jinsei o Sosogikomi 25-nen, Imasara Saikyou no Boukentan Midori Kashi no Akira

When a monstrous attack leaves his childhood friend Sora hovering on the brink of death, Touru faces a desperate race against time. The only cure lies within his own meager abilities—a skill called "Restoration" that can heal wounds, but at its lowest level can barely mend a scratch from a goblin. With no other options, Touru dedicates himself to an arduous journey of survival and self-improvement, pouring every ounce of his being into a talent that the world deems worthless. Twenty-five years pass in the blink of an eye, a quarter-century of relentless struggle against insurmountable odds. Yet Touru's unwavering devotion has borne fruit beyond anyone's imagination. Through sheer grit and the accumulation of countless battles, his "Restoration" has transcended its mundane origins. It is no longer a simple healing trick; it is the absolute power to "Freely Restore any Subject to its Past State," a versatile and godlike skill that bends reality itself to his will. Forged in the crucible of a lifetime's worth of peril and honed by masterful instincts, Touru emerges from obscurity with the strongest ability the world has ever seen. What was once considered a useless gift has become the key to rewriting destiny itself. Now, with Sora's salvation finally within his grasp and a power that can reshape the world, Touru steps out of the shadows to etch his legendary name into history.
