Cyclo Owen. As a genius boy engineer, he was a person of great promise in the circles of magical tool production. However, at the age of 16, he was given the job skill of “Clock User” in a skill-giving ceremony. In this world, it was forbidden for those with job skills to work in any other occupation. Thus, Cyclo’s path as a genius engineer was cut off.

However, Cyclo did not despair and worked diligently as a watchmaker and contributed to the craftsmen’s guild by using his job skill as a Clock User. One day, however, the guildmaster of the craftsmen’s guild banished him from the guild, saying that the guild did not need a watchmaker, a profession with little usefulness. Cyclo, who has lost his job, faces further despair. He happens to hear that a police officer is planning to r*pe Miranda Lilibel, the neighborhood apothecary’s lady. Since the police is involved, he cannot carelessly report the crime. So Cyclo decides to stop the plan that night. He tries to restrain the police officer who is about to attack Miranda’s house, but he is detained by the officer instead. He is then accused of trying to r*pe Miranda, and when Miranda hears the commotion, she tells Cyclo she has misjudged him.

Cyclo is thus made a criminal for attempted r*pe, and is sent to a remote area to explore the worst dungeon in the world. In the frontier, imprisoned adventurers are considered to be at the bottom of the heap, so Cyclo is looked down upon. Furthermore, due to rumors spread by his younger sister, Alice Owen, a well-known genius alchemist among adventurers, he is treated as incompetent here as well.

He is then mistreated by adventurers who makes uses him as a baggage carrier, and is pushed down to the bottom of a valley in the dungeon.

At the very bottom of the dungeon, Cyclo wished he could use his Clock User abilities to stop his internal clock. Then his hunger stopped. This led Cyclo to understand that his skill coul manipulate anything that could be counted as a clock.

Thus awakening to his true power, Cyclo escaped from the deepest part of the worst dungeon. In recognition of his achievements and abilities, he is recognized as an SSS-class adventurer.

On the other hand, those who had driven Cyclo to misfortune are now faced with misfortune in Cyclo’s absence.
