Oh, how Natsu wished that he could do exactly that. If his rage had been enough, then he would have seen the horde of dragons disperse before his might. Moreover, if he was simply strong enough, Lisanna would not have had to stand the trauma of losing a limb. In the past, any enemy of Fairy Tail that had stood against them was dispersed, either by his might, or by the might of another. This time. . .this time, his conviction just wasn't enough. The dragon slayer could not focus on winning, and instead had to focus on surviving. Managing that was a difficult enough task with just himself, but with the bevy of guild members out there, still fighting. . .things were going to get a whole lot more difficult.
With those forces arrayed in a row against him, he knew that some would have coached him to quit. He had assured both the survival of himself, and of the woman he loved above all else. That was enough of a victory for some, but that 'some' was a selfish breed. Individuals like that would have not even gotten to catch a whiff of Lisanna, let alone be linked in love with her! Natsu would not devolve into that sort of individual, not today, and not ever. Hell was staring him straight in the face, and he was willing to spit into its gaping maw.
A look of sheer determination wiped out the despair once marking his countenance, as he looked away from her, and towards the chaotic situation ahead. All of Crocus had devolved into a bloody scrum, with body after body of the defeated lining the streets ahead. This had to end, and he would see to it that it would. It didn't matter if it took a day, a week, a month, or even a year. Natsu Dragneel would fight for the survival of not only himself, but for everyone else in Earthland!
"Lisanna. . .I'm going to make it stop. If you can fly away from here, try to do that. If you can't, then that's fine too. I'll tear apart any dragon that tries to come our way!"
Willpower wormed its way into his tired muscles, and the exhaustion that threatened him was overcome by strength. He took a step forward, only to kneel once more. A dirt encrusted hand set itself against Lisanna's forehead, looking both to feel the warmth of her blanched skin, and to wipe away the excess hairs that dotted it. So long as he remembered her warmth, he would fight, and so long as his heart beat for her, he would win.
"This all ends now. I'm gonna make this world happy for you again, and nothing's going to stop me. Nothing!"
