Of course I like the GMG arc the most! Its soooooooooooo addicting ^^ And also the battles are very much fun to watch!This arc is mysterious and awesome at the same time <3333 And my seconde favori arc is the edolas arc,its also very awesome... Also,my least favori arc is the 'Key of the Starry Skies' arc :)
My favori arc is the tenrou island arc because the grimoire cœur, coeur comes to attack them which almost killed them. For some reason, zeref is my favori character in the arc. My 2nd favori arc is the GMG. 3rd is Edolas.:)
Honestly, the Tower of Heaven Arc is my favourite, good fights, ending and plot. The current GMG arc isnt doing it for me... The plot is botched and for anyone who is it not a main character *natsu and lucy* gets a nerfed, gagged ou ass-cheeks fight! However the anticipation of the dragons involvement does put it in my haut, retour au début three arcs.
