Intro: Well, would ya look at that! Trollshima actually made something canon and didn't try to kill it! *whispers* What do you mean he almost did? *back to normal voice* WHAT?! Trollshima!! I was proud of you for a second!!
Proof: Think of it as Fairy Tail's Nalu before Nalu even existed. There's really no difference. Except perhaps the fact that these two are clear cut canon, with a kid!
What I think: It's a cute ship that you just can't ignore, especially since Rave Master was Trollshima's baby just before Fairy Tail. It's the original Nalu. There's not really all that much I can say. It's a good ship.
