The Noble Unlocker's Ascendancy

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