A Railgun In Fairy Tail, Diablo Saga 7: Part 2

This is The End..And the Beginning.

Natsu panted as he clambered through the rocks and rubble all over the city.. everywhere he looked, various spirits, people from other worlds.. everyone was encased in stone..  everyone had been rendered nothing but a statue..

Natsu wasn't afraid of any attacks.. or having to fight any monsters like it had been in the strange alternate apocalypse he had experienced when Asgawrath remade the Multiverse. He already knew.. there was nothing here..

It was all empty.. gone.. not a speck of life left.. not even hollows were alive right now.. Hueco Mundo itself was probably frozen over with lifeless statues of the masked demons..

Nothing except him and Rosario had escaped Dark Fulas... who now ruled a silent world..

Finally they approached what used to be town hall.. it was now a ginormous black towering castle.. with banners that dangled lifelessly, for there wasn't even any wind.. this was the Omegaverse of Dark Fulas... complete.. and utter.. silence..

"Almost reminds me of Salem's world.." murmured Rosario.

"Salem?" said Natsu.

"Some nutter of a mortal who experimented with Hollows.. there are different types of hollows you know.. some can be formed from something beyond human souls... as mere separate creatures who hunt humanity... they call these Grim.."

"Weird." said Natsu as he looked up at the massive castle and approached the entrance.

"No need to be shy by the way.. I don't think Dark Fulas knows you're still alive.. or even cares if she knew.." said Rosario. "There are no traps.. no obstacles... just.. walk right in.."

"I know." said Natsu with a mutter. "So.. I just beat her up?"

"No.." said Rosario. "Even if you still had your full power.. that wouldn't be enough.."

"Wait.. I don't have my-!?"

"This world is caught in her Dark Binding Spell.. a Binding of Existence itself.. powers related to divinity or an existence beyond human are sealed in this realm.." said Rosario. "as a Numensapien, I have no power in this world... and your Dragon Lord and Dragon Born powers are useless as well.. but you still have power... as.."

"As a regular Dragon Slayer I guess.." Natsu said as flames ignited on his fingers. "D.. dang..  since it's a magic that can be learned as a regular mage power.. "

"Hmm.. you're smarter than you seem you know.." said Rosario. "And here I thought all you did was yell a lot about Nakama and charge blindly... it's funny you know.. Dragon Slayer magic without the Dragon Born ability is actually something normal Dragon Borns have to LEARN.. being able to use their magic without having their Ability active.. as a defense mechanism in case the ultra rare situation like this happens... Misaka wouldn't have to learn it.. she has esper powers after all..  but you.. you are one of those few Dragon Borns who learned to use regular Fire Dragon Slayer magic before awakening a Dragon Born ability.. I wonder why that is.."

"I dunno.. Igneel just taught me.. that's all.."

"Instead of just right off the bat  using a flame awaken spell to help you instantly awaken your magic blood? intriguing." murmured Rosario. "And here I thought Igneel detested Irene's inventions...  perhaps.. did he foresee a moment like this?"

Rosario stepped over to the massive door of the castle. "Natsu... know that while I cannot help you when we go in... I am watching... I can lend you my support in other ways that don't involve combat... I know that this isn't in your nature.. but I'll ask that you try to talk to Fulas first instead of trying to throw a punch... remember she is currently as powerful as the entire Omegaverse, she is effectively the one right below God himself in power right now.. no power in existence is capable of beating her.. unless.."
