Blue doesn't really do anything for me, he isn't in alot of episodes, and he's supposed to be from if im not mistaken monster hunter or something, the creator of fairy tail also created that show, but the interactions with Grey, Natsu and Erza coupled in with newer charecters later introduced makes it entertaining, but too me it seems like they rush through the arcs too fast, up until the one they're at now in the show and manga. BTW Tigerkinney, awesome work as always. Once I catch up in One Piece im most def gonna check out some of these.
