Half a century has passed since humans took to the skies to hunt dragons. Although dragons pose a significant threat, every part of their bodies is extremely valuable, and brave dragon hunters, known as "drakers," risk their lives aboard specialized airships to pursue them. However, despite the thrill and excitement of the hunt, a draker's life is far from easy. Ostracized by society, drakers have no place to call home. Life in the air is no easier either: maintaining an airship is tedious and costly—and dragons are even harder to catch, as each one is unique. One of the last remaining such airships is the Quin Zaza. Its courageous crew includes Takita, an eager newcomer trying to earn her place on the ship; Mika, a reckless but highly skilled hunter; and Jirou, an earnest young man chasing both dragons and his past. United by the same goal, these hunters face arduous aerial battles that involve daring feats of skill, strategy, and more than their fair share of danger.
