In the Western world where magic and machinery blend together, Arthur, a boy from Cake Village, and his friend Linna were involved in a world-wide dispute because they disrupted the evil ritual of the mysterious wizard Druid. In order to save their homeland, they join hands with the false knight Toby to embark on an exotic adventure. On the way, they encounter the cold-faced dragon-born girl Maureen. The four of them had a wild ride all the way, fighting wits against ridiculous enemies, breaking through various magical mechanisms, and uncovering the truth of the world as they gradually grew up. They became stronger amidst laughter and frustration, and finally worked together to defeat the Druid, prevent the world crisis, protect their homeland, and each achieved self-growth.
