Mastering the art of riding and taming dragons is simple for most students at Ansarivan Dragonar Academy—except for first-year student Ash Blake, whom his classmates label the "number one problem child." Ash is the butt of jokes at school because, despite his unfashionably large star-shaped brand that identifies him as a future dragon master, he has nothing to prove it. His dragon has never appeared. Until now, that is. On one fateful day, Ash's dragon awakens in full glory, but looks unlike any dragon seen before—taking the form of a beautiful girl! To make matters worse, Ash soon finds that this new dragon has plenty of attitude, as she immediately declares that she is the master, and he is the servant. Ash's troubles with dragon riding have only just begun.
