In this world, when people turn 15, they are granted a skill from the heavens. I, Hiraku Mattoh, was born into a family of Sword Saints and was hailed as a prodigy from a young age. Everyone was certain I would inherit the same title. However, at my skill appraisal ceremony, I received "Unlocker"—a seemingly worthless ability that could only "open what is closed." Disappointed, my family branded it a trash skill and exiled me. Left adrift, I soon discovered its true power. By unlocking my status window, I could freely acquire skills, obtain item drops, and grow stronger without limit.
