National Job Change: I'm Stuck As the Weakest Dragon Tamer?!

Synopsis

Luke Foster thought he was doomed when he awakened as a Dragon Tamer, the most useless hidden profession in existence. Dragons are so rare and powerful that for eight centuries, no Dragon Tamer has ever succeeded in taming a dragon. But without one, he can't even unlock his basic skills, leaving him powerless in a world ruled by fighters. Then everything changes after Luke activates the Super Treasure Map System. The mysterious system leads him to the ultimate prize: a real dragon egg! And so, this "weak" Dragon Tamer is about to flip the world upside down.
