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