A Hundred Years to Forge a Sword

A thousand years ago, a rift split the sky, and strange creatures descended from beyond it. Humanity retreated behind towering walls, tempered their bodies with vital energy, and struggled to survive amid the danger.

Everyone in this world believes that vital energy is the path to martial strength, and that heavy blades are the way to defeat one's enemies. Only one orphan, with no family or support, picks up an old, slender iron-bamboo sword and takes the ancient martial path that the world considers absurd.

A hundred years roll by, and hardship never lets up.

It wears down his solitary nature, weathers his sword, and wears down the people of this world, who still love to joke and talk about a hot meal even in the depths of despair.

Disaster looms over the city, and all living things struggle to survive. With this sword, he cannot cut away all the world's suffering. He can only endure, little by little, alongside the world, through trials that repeat again and again.

This sword is called A Hundred Years of Tempering.
