The Armoured Wizard
Natsu and Lucy start looking for a new job to take, but just then Erza, the strongest female member in all of Fairy Tail, returns. She's so powerful all the other people in Fairy Tail are scared stiff, and she immediately asks Natsu and Gray to come help her on a mission. Lucy tags along to keep the two of them from fighting, and on the train Erza tells the story of how she learned of the evil plans of Eisenwald, a Dark Guild, and how she intends on stopping them. But can the four of them really take on an entire guild by themselves?
