Every year, the Church distributes a batch of weapon blanks for children to practice with. They serve as the first step into training, beginning in adolescence. Each person gains special abilities through their own weapon, and can unleash even greater power by combining them with specific martial techniques. At the end of the Three Rivers lies the Corridor, the origin of all weapons. Countless people seek powerful weapons: some make a name for themselves in one fell swoop, some meet with defeat, and some become spirits of the Corridor. A small number of people are born with weapons, making them far stronger than their peers. Feng Yu's bonded weapon, however, only awakened when he fused with a blank. Easygoing by nature, he never delved into his own past. It was only after leaving his master at the age of twelve that he truly embarked on the journey that was his alone.
