Dragon Sorcerer

Nico, a young dragon of barely fifty, is rudely chased from his home by a group of murderous adventurers. Of his entire clutch, only he and one sister remained, but now he is alone. Isolated and hungry, Nico's magic awakens, bonding him with Cami, a brave young woman. To hide from the adventurers' pursuit, Nico takes on human form. However, once they discover that both he and Cami have magical abilities, they are required by law to attend the Imperial Academy. Of course, he has to hide his true nature, which isn't always easy given a dragon-sized ego.
