Fairy Tail is one of the best manga I've read. It should be put in the conversation with Naruto, Bleach, OP, etc. I read all the chapters and I haven't been disappointed a single time.
Can't wait for Gildarts vs Natsu. Also, I want to see what Mistgun taught Mest. He was one of the strongest in Fairy Tail and a lot of what he can do was not shown, so I wanna see what he taught he pupil.
