The backstory wax a bit of an asspull, that came out of nowhere. Meh, at least FT is defeating enemies with a bit more strategy these days other than the usual nakama power.
So Gajeel went from Iron Dragon Slayer > Shadow Iron Dragon Slayer > Shadow Steel Dragon Slayer? Wondering if he'll always be a Steel Dragon Slayer now.
One of the, if not the best arc of FT imo.
Hiro has really stepped up his writing, but I really wish he'd evolve past this formulaic way of defeating his opponents (i.e. FT getting their asses kicked, having a heartfelt moment, then becoming more powerful somehow (which is a lot better now, seeing how this growth in power doesn't stem solely from their feelings and is actually getting some explanation), then kicking the enemy's ass).
