There is nothing wrong with a boy being a nalu shipper. I mean look at makarov. I know he's a little crazy but he ships nalu. Yes he is an anime character but who cares. Fairy tail was not aimed towards girls alone. Boys would love it too because of all the fighting. The girls would like the slight hint of romance as well as the fighting if they are into it. I know I love everything about fairy tail. The fighting is actually my favorite part because we get to see just how far natsu, gajeel, and gray will go to protect Lucy, levy, and juvia. We also get to see just how pissed off natsu and gajeel, as well as gray, get when the girls are hurt by someone. They practically murder the person who hurt the girls. Gray claims not to like juvia, but to those watching, it is obvious that he does. Why else would he jump in front of a magic spell just to save her life?
