Author's Note: Apologies for the bad summary.
Natsu fell to his knees, staring at his trembling hands. When he finally properly processed the information he looked up to at the tearing red-head with wide eyes. "W-what…L-Lucy is…was in the factory!?"
Erza turned her head away and sniffed but the pink-haired mage clenched his fists, refusing to look at the others and simply to focus on getting the truth. He stood up angrily and felt his flames surround him.
"What do you mean by SHE WAS IN THE FACTORY WHEN I BLEW IT UP!?"
Gildarts tried to calm the boy, whose magic power was sky-rocketing, and took a step forward. The next second, everyone even Master Makarov was blown away as Natsu glared at the ground. Then he threw his head back and let it out. A horrifying, blood-curling scream tore through the air. No, not a scream. More like a roar: the outraged, furious roar of a dragon grieving over the death of its mate.
Not understanding how close the 2 had been, Lisanna tried to place a comforting hand on Natsu's shoulder, ignoring her guild-mates screams: all fearing for her life.
The moment she touched the enraged dragon slayer's shoulder, her hand burned and she cried out in pain, jumping back. The others tried forward to shield her, but Natsu's power was still rising. The sheer aura of Natsu's presence made the atmosphere one hard to breathe in
They all sucked in a terrified gasp as Natsu glared over his shoulder at the shaking Lisanna, his eyes ablaze and his fangs out.
"Leave me alone," he snarled. And with that, he shot into the sky, a giant fireball and all that power, all that suffocatingly tremendous power was gathered. For a moment, everyone on Earth felt their eyes tear at the painfully bright light.
Then, with a roar: Natsu directed all that power at a mountain range nearly 100 miles away. The entire landscape turned to flat ash.
Natsu fell to the ground on his side, and as his team-mates slowly approached him. He stood up and ran off, wiping the tears from his eyes.
