Ash Blake may be a senior at Ansullivan Dragonar Academy, but he's not your typical student. Not only can he ride any dragon, but his own Steed, Eco, has the decidedly un-dragon-like body of a beautiful young girl! As preparations begin for the Academy's 500-Year festival, the student council's vice-president returns to school after a long absence. But his focus doesn't seem to be on the festival at all. He's got other goals in mind - like making both the student council president and Eco his very own...!
