Stronger Than You (Graylu)

Lucy Heartfilia is once again the first to lose all her power in another mission with team Natsu. The team have her back, like they always have and always will, but Lucy can't help but feel that she is holding the strongest team in Fairy Tail back with her average at best magic store. So, despite new relationships coming to light with a certain ice mage, she decides to abandon Fairy Tail in order to train and make her long line of celestial spirit mage ancestors proud. Not out of need for revenge or spite, but out of pure determination to be better.
Juvia Lockser can tell that her Gray-sama doesn't love her. He is talented and powerful. She is nothing in comparison to him in her mind. Just a normal water mage, unimpressive and bland and crazy. She can't fight and she isn't pretty. She is unworthy of loving him until she can get stronger.
Cana Alberona feels defeated after another failure at the S-class trails, losing to Freed. She no longer cares about her need to prove herself to her father, nor does she mind that she cannot call herself an S-class mage. She just feels she has lacked improvement in the last five years, like she peaked at 13.
So when lucy tells her former teammate about her idea to leave, and Juvia overhears the pair, the three girls decide to set off together, to better themselves and become as strong as they can be. A year later they return and old relationships crash back. Will the three be forever partners? Or will old feelings, old friends, and a war on the horizon break apart our team of underdogs?
