Fairy Tail: Echo

Fairy Tail: Eternal (妖精の尻尾： 永遠の Yōsei no Shippo: Eien No) or Eternal for short, is a storyline written by TDS. In order to differentiate itself from the actual series and allow more creative freedom for the author, Eternal is set in a alternate reality where the plot greatly differs from canon.
