Instead of colliding against the united force Alvarez possess with an equally massive force, Erza has decided to keep things simple and send in a recon team consisting of Natsu, Gray, Lucy, Wendy, Mest, Happy, Carla and herself to infiltrate the Alvarez Empire and save Makarov (if he is indeed captured). Unbeknownst to Erza, Gajeel with his abnormal hearing has overheard their conversation and has plans of his own to infiltrate the Alvarez Empire with a group composed of the Fairy Tail Team B members. With the revelation of the Spriggan Twelve and the number one Ten Wizard Saint becoming part of it, it has become clear that in order for Fairy Tail to succeed in saving Makarov, they will have to clash against mages that possess magical power equal to or greater than the level of Ishgar’s strongest mage.
