Kamaseinu na Chuunen Boukensha wa Kyou mo Ganbatte Ikitemasu.  

Georg Kylie, a seasoned adventurer in his prime years, leads a routine existence that seems mundane compared to his rugged appearance. Every day involves waking up early for breakfast, donning his armor, heading to the Adventurer's Guild, receiving a commission, completing it, working on side projects as a jeweler craftsman, socializing at his favorite tavern, and retiring for the night. Despite this monotonous routine, Georg remains vigilant for any signs of danger, such as sightings of sub-dragons, which are Class A monsters. One day, while Georg was minding his own business in a tavern, he was mistaken for a molester by a young girl who wanted to sell sub-dragon scales. He tried to warn her about her actions, but was beaten by her companion. After this unfortunate incident, Georg's peaceful existence was shattered, leading him on a series of unexpected adventures that he never imagined he would encounter in his later years. Georg's journey takes us through the thrilling yet perilous world of a seasoned adventurer in his prime years.
