Revenge is the one thing that's on their minds. When Fairy Tail is attacked by the Horned Serpent guild, all Team Natsu wants to do is get revenge. They form a plan to ambush the guild head on, but they didnt expect to be knocked out by that very guild on the way to their designated location. A team within the Horned Serpent guild - called the Haki Order- tells all of the members that they are seeking for something within the Fairy Tail guild hall, an object that will be the last puzzle piece into resurrecting the Dark Mage Zeref. To obtain their goal, the Hakai Order erases everyones memories and gives them false ones. What will happen to the rest of the mages in Fairy Tail, how will they regain their memories?
