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

Grimmjow + Accelerator = You Dead

The Song is Grimmrazer's theme.

"Most intriguing.." Oculus's energy eye roved around as he used his multiple tentacles to pour strange substances and combine them in beakers.. swiveling the beakers around to ensure they mixed.

Oculus's lab was a room completely made of smooth obsidian stone.. everything around him, from the chairs to the tables holding the beakers and strange metal instruments were made of pure blue light, solidified to look like some extra purified ice.

"What's so interesting?" Diablo walked in.. the Lance of Gungnir in his hand.

"Corruption's DNA and the Vasto Lorde's are similar.. not the same.. but similar." said Occulus. "Around a 60 percent match. Hollows and Corruption might have a similar source.. that's just one theory.. the other is.. that Corruption is comprised of 60 percent Instinct."

"Studying Corruption now?" said Diablo. "A dangerous game."

"Well basically, being near you alone is dangerously close to the Corruption." said Oculus. "So really I have nothing to lose.. and every bit of research to gain.."

"So you say." said Diablo. "Though I have no complaint in that regard. Your research has contributed to us heavily in the past.. in the old days.."

"Ahhhh.. the old days.. the days when Nebulosos was at the height of it's glory." said Oculus. "I remember before I defected to you.. I was once a pediatrician. I still remember all the Numensapien children I would perform checkups on.. while disease was rare in our species... if disease ever DID strike.. it was important that my job be done professionally.. I remember Fulguras was one of the ones who entered my office often.. when she was small.. she was often sickly..."

"Ironic." said Diablo. "Given the strong girl she became after... she inherited the resilience of her father."

"The battle between you and Ronin.. I hear it was a battle of legend..."

"Indeed it was.." said Diablo. "Egnim, the first of my generals remains the only one to have witnessed it."

"Yes.. and he gave me rather fragmented details on the matter itself." said Oculus. "So the data I was able to gather on that was.. I'm afraid to say.. rather useless at best.. not to mention quite sparse."

"Hmm.." said Diablo. "Ha our prisoner been a bother?"

"Amor is silent as always.." said Oculus. "I doubt she's of any use to us anymore.. though I would like to keep her around for the research, if you don't mind..."

"I would like to eliminate Mikoto Misaka from our equations as soon as possible." said Diablo. "She has been too much of a risk to keep alive.. Oculus.."

Oculus sighed. "So that's why you REALLY came down here.. well.. Night Reveler's doing his usual thing.. feel free.. I think he's ready to go on a bloody rampage now...

Oculus thrust out a tentacle.. and a wide door opened in the room to reveal Night Reveler dancing around an empty large room, singing.

"Lalalala the sky is red with blood.. lalalalala...murder murder.. murder in the first.. murder murder.. murder in the first! Yay!!"

All around the walls, there were words in blood saying: Redrum Redrum Redrum Redrum all over the place.

"Ohhhhhhh Mr. Devil guy? Wanna make a silly deal? Teeheeheehee.. You get me an X Box, And I go kill a baby and put it in a blender for Tortilla chips!!"

"It's your turn to shine Night Reveler." said Diablo.

"Ohhhhh." said Night Reveler. "Cooool.. REDRUM FOR EVERYBODY!!! HAHAHAHAHAHAHAHAHA!!!!!"
