The Last Dragon Tamer

On my Class Change Awakening, I awakened as the strongest SSS-class Dragon Tamer. The crowd laughed, as dragons were extinct, making a Dragon Tamer useless. My girlfriend left me. A System, my Dragon Seeking Formula, descended. That night, I hatched Dragon Girl Nia. On the Secret Realm assessment, I descended with a real dragon, dominating everyone. They exclaimed, 'A dragon! It's a real dragon! The rulers of this continent, the dragons, have returned!'
