Lizel, the gentle noble from another world, generally spends his time relentlessly pursuing his hobbies and challenging himself inside labyrinths alongside his party. This time, Lizel, Gil, and Eleven stumble upon an arm wrestling contest for a prize that Lizel desperately wants: a new book. Will he be able to convince Single Stroke Gil to enter the contest for him? And later, when a sudden horde of monsters appears near Marcade, Lizel notices that this isn't any ordinary invasion: these monsters are strategizing and targeting certain areas of the city. Will C-Rank Lizel be able to convince the fellow Adventurers defending Marcade to change their strategy in the face of such an abnormal invasion?

When Lizel mysteriously finds himself in a city that bears odd similarities to his own but clearly isn't, he quickly comes to terms with the unlikely truth: this is an entirely different world. Even so, laid-back Lizel isn't the type to panic. He immediately sets out to learn more about this strange place, and to help him do so, hires a seasoned adventurer named Gil as his tour guide and protector.Until he's able to find a way home, Lizel figures this is a perfect opportunity to explore a new way of life adventuring as part of a guild. After all, he's sure he'll go home eventually... might as well enjoy the otherworldly vacation for now!
