There was an interview with author Hiro Mashima and everyone were saying that he confirmed their feelings for each(Nalu) but im not sure if its confirmed that they will be getting together at the end but I do hope so. And i think lucy will win this one and I don't think she a fan service character, she has so much more too her and anyone that says otherwise aren't reading the manga
And I think she keeps losing bc the opponents are just so strong and she started too late at learning magic. Just like in sports if you start too late you can't be a professional sport player bc other opponents have done what you are doing much much earlier so they are on whole different level. Lucy is at the lvl of a S wizard but she will always be few steps behind her teammates plus also her magic isn't meant to be fighting in person but she invented something more powerful
Reading this somehow becomes a quest for me. I'm not enjoying much of this anymore. Just reading for the sake of it. To know the end (or JUST GIVE ME NALU!!!! ). Still, Eventhough I keep getting disappointed over Lucy's defeat (Like CMON SHE'S POWERFUL TOO . Don't just make her the fanservice girl
