A Railgun In Fairy Tail, The Diablo Saga: Book 2, Time.

The True Hydra Head.

The song above is the true Hydra Head theme

Now Mikoto didn't really truly consider Touma and herself married at the moment. Especially given that she didn't consider this a real timeline. But she was glad that it was him she married in this timeline nonetheless.

Afterwords, Touma laughing said that the fact that he actually was 18 and legally able to marry never occurred to him due to the massive amount of time skips that had occurred ever since Dravis had first been defeated years ago. Which got Mikoto extremely flustered when she realized that compared to many other '16 year olds' she was practically 20 thanks to the 5 years she had lost at one point.

But now.. thanks to Supremos, at least Mikoto suspected Supremos had something to do with it... she had managed to sneak away in the crowds.. something about what Supremos said to her.. and how he seemed to know this wasn't the real timeline.. scared Mikoto. And she noticed more terrifying things.. like how nobody, none of the Numensapiens who survived in the true timeline were around.. none of them.. as if.. as if this weren't just some sort of alternate timeline.. as if this were some illusionary world that had the ability to resurrect the dead of this world..

Coluber was waiting for everybody at the entrance to the portal out... looking extremely exhausted.

"You have no idea... what a lecture from my Mom is like.." Coluber muttered.

"Don't I?" said Mikoto as she approached and petted Coluber's head. "She's the one who thinks I'm an inferior peasant not worthy to even poke a finger on the Lance of Gungnir.."

"Oh yeah.. forgot.."

"As everyone crossed through the portal one by one.. keeping an eye out for any watching Numensapiens.. Mikoto stared back at Primaris.

"You okay?" said Elli as she clung to Mikoto's head.

"I don't know.." said Mikoto. "I... I don't want to leave yet.. there's.. .something strange about this world.. and.. I still feel that strange feeling Gray mentioned.. like Diablo is somewhere in here... yet...and this world.."

"Hmmm.." said Elli. "I'm curious about Erza though.. I want to know what she was like before she reincarnated.. and how she reincarnated in the first place.."

"Something tells me we're going to find out soon enough." said Mikoto.

Mikoto turned to walk through the portal, being the only one left along with Elli who was still outside.. but as she made to climb out... she heard a familiar voice..

"FULGY!!! WHERE ARE YOU GOING!? WAIT!!!"

Mikoto turned around and saw Ava running after her. "A-Ava!? No wait!! you don't understand!!"

"Fulgy!! Everbody's gathering for the after marriage ceremony!! Come on!!" said Ava grabbing Mikoto's hand.

"A-Ava, I can't!!" Mikoto struggled against Ava's grasp as she climbed halfway out the portal.. half her power shroud was replaced with a pink t-shirt and shorts.. as she was halfway between human and Numensapien form

Ava stared with an open jaw at the phenomenon before her. "F-Fulgy!?"

Natsu and Gajeel suddenly jumped in, and helped pull Mikoto out of Ava's grasp through the portal... Mikoto fell right into the dusty.. barren, and dark razed world of the true Nebulosos..

Ava stared through the portal at Mikoto's human form.. she reached a hand out through.. and the hand became a rotting boney skeleton..

Ava let out a short gasp of realization.. then she began to cry. "I-I remember... this... this isn't real is it? I remember.. you killed yourself.. Fulgy.. I.."
