As a Watchmaker, I was kicked out of the craftman's guild because my incompetence was deemed unnecessary, but I awakened to my true power in the depths of the dungeon.
In a world where skills are supreme, Shikuro is given the incompetent skill of Clock-user. One day, Shikuro, who is looked down upon by others, is accused of rape and sent to the frontier, where he is pushed down a hole that leads to a dungeon's deepest level.
In the depths of his desperate situation, he thought to himself, "If only I could use my clock-user ability to stop my stomach clock as well. Then the hunger would stop." This triggered the awakening of his skill Clock-user. Eventually, he makes full use of his abilities and is recognized as an SSS-class adventurer.
