Learning to ride and tame dragons comes easy to most students at Ansarivan Dragonar Academy - except for first-year student Ash Blake, who is known by his fellow classmates as the "number-one problem child." Poor Ash is the laughing stock at school because, despite his unfashionably large star-shaped brand that marks him as a future dragon master, he has nothing to show for it. His dragon has never appeared - until now, that is. One fateful day, Ash's dragon awakes in full glory, but appears different from any dragon ever seen before - it's in the form of a beautiful girl! What's worse, Ash soon discovers that this new dragon has attitude to spare, as she promptly informs him that she is the master, and he, the servant.
