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. (Source: Micro Magazine-sha, translated)
