Great explanation though... a lot of people love the tenrou arc a lot which I can't blame them for, it was tough as shit.. I had to include all the arcs dealing with the Balam Alliance since when I first picked up on FT thought they were gonna be the biggest baddest villians of the series (mostly was right)

GMG set the standard for everything to me since it included so many characters and future villians

and OS arc, the simple fact that we see the backstory of the OS members is one of the main reasons I loved that arc. From sorano being yukino sister to cobra and cubellious becoming Kinana to Jellal becoming a good guy, all around good arc
