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 segundo favorito arc is the edolas arc,its also very awesome... Also,my least favorito arc is the 'Key of the Starry Skies' arc :)
My favorito arc is the tenrou island arc because the grimoire coração comes to attack them which almost killed them. For some reason, zeref is my favorito character in the arc. My 2nd favorito 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 or ass-cheeks fight! However the anticipation of the dragões involvement does put it in my topo, início three arcs.
