Nagata Yuri Dreyar is a proud and famous member of Fairy Tail. His celebrity name, 'Devil Dragon' is known all over Fiore. A century job seeking a Dragon or Devil Slayer pops up in Fairy Tail and Nagata decides to take it. He must walk for days to find something that may be a hoax. If the job is real, it is right up his alley. Nagata suspects that the sighting of a "dragon with demonic horns" near a far away mountain may actually be a Devil Dragon, a legendary being that was extremely rare, even in the time of the dragons. Being a Devil Dragon Slayer, Nagata takes the chance of wasting weeks of his time for a suspicious job. If the job is a hoax, he could be facing an ambush from a dark guild or unknown, hostile group. If it isn't, Nagata has to fight for his life to slay a beast that hasn't been slain in recorded history.
