I actually guessed it! Actually no I didn't...I was like it had to be one of them. It's definitely Natsu. But in the end it was lucy...makes kinda sense? I still don't understand why she's such a big part of fairy tail. She literally joined in due to chance (meeting natsu) so why is she such a centr ...
Fate...it seems to be a central aspect of the series. Their meeting was not coincidence but fate. If you think about it too even indirectly she is the one that pushed Natsu into many of the events of the series. The stuff with Phantom was because of her and the Moon destroying mission was partially motivated to help with her rent. Succeeding in these that to more missions and arcs as their reputation improved. Lucy generally pushes Natsu and Natsu creates miracles.
