Most students at Ansarivan Dragonar Academy find riding and taming dragons to be a breeze - all except for Ash Blake. The first-year student is notoriously known as the school's "number one problem child" because despite having a large star-shaped brand that signifies his potential to become a future dragon master, he hasn't been able to summon his dragon. This has made him the subject of ridicule among his peers. One day, Ash's dragon finally appears, but much to his surprise, it's not in the form of a traditional dragon. Instead, it's a stunning girl! To make matters worse, she makes it clear that she's the master, and he's the servant. Ash realizes that his troubles with dragon riding are far from over.
