A Railgun In Fairy Tail, The Diablo Saga: Book 3, The Will of Fire

The Eyes That Dominate the Darkness.

"I guess I'm fighting you.. whoever you are." said Shizuri.

"Kakuzu." said Kakuzu as his arms slid back together.. and the tendrils on his back slithered back into his body. "A Mercenary and former member of the Akatsuki."

"I don't know what the Akatsuki is.. but I think I can understand the Mercenary part." said Shizuri. "I used to be a Mercenary of sorts."

"K-Kakazu.. one of the only shinobi to ever survive a fight with Hashirama, the God Shinobi.." Ayna said fearfully from where she hid behind Shizuri's leg. "You're insane girl.. fighting him.."

"Heheh." Shizuri chuckled. "Well.. even if I didn't want to fight him.. I've got no choice.. I'm kind of cornered here."

"So who are you?" said Kakuzu. "You don't look like a Ninja.. and yet you managed to give Deidara a tough time."

"Shizuri Mugino.. or the Meltdowner if you'd like." said Shizuri. "I used to be a mercenary of sorts myself, but I changed my line of work to creating myself a guild."

"Guild.." said Kakuzu. "I've never heard of such a thing.. but.. I can say this much, I fight for my own interests alone.. and currently, my interest is staying alive.. and the best way to do that, is to utterly destroy you.."

Kakuzu held out a hand.. and instantly, the 4 masks tore themselves from his back.. dragging with them, the thick gray tendrils from Kakuzu's body.. and they separated into four beings, each of them with their own unusual humanoid body formed from gray tendrils with masks for faces.

"Each one of these mask contains one of my hearts." said Kakuzu. "To kill me.. you have slay me 5 times.. I have lived hundreds of years girl... and gained the experience of countless shinobi... what do you have?"

"A stubborn attitude, and disintegrating beams." said Shizuri. "Show me what you've got!"

"Very well!!!" Kakuzu thrust out a hand, and the 4 masked tendril beings dashed at Shizuri with astounding speed that surprised even her.

As the beings came close, Shizuri spread her arms out. "CROSS BEAM OF THE ANTIMATTER DRAGON!!!"

Shizuri's Antimatter Arms all spread out their ribbon fingers and a massive hailstorm of green energy beams rained down upon the 4 beings. But they moved with incredible precision, easily dodging each attack.

The red masked being came up behind Shizuri, the mask opened it's mouth. "Fire Style! Hard Worker!!"

A fire ball exploded from the mouth of the mask.. and Shizuri rolled out of the way.. however, the moment the flaming blast made contact with the ground, it exploded with tremendous power.. sending a massive flaming explosion rippling out.. and blasting Shizuri off her feet.

"DAMN!!" Shizuri grabbed Ayna with one arm as she flew and faced her back to the flames.. protecting the cat from harm.

"Wh-what are you doing!?" Ayna cried out.

"Go!! GET OUT. FLY!!!" Shizuri roared, throwing Ayna into the air away from herself. "This fight is mine!!"

Shizuri turned to the flame mask being "ROAR OF THE ANTIMATTER DRAGON!!!"

The powerful blast of energy neared the flame mask, but not before the Wind Mask being launched itself in front of the blast and opened it's mouth. "WIND STYLE: PRESSURE DAMMAGE!!"

A tornado-like mass exploded out and blasted against the energy beam.. before turning into  a giant explosion of wind.. blasting out in a wide area.. creating a 40 meter wide crater.

Shizuri crossed her Antimatter arms together and created a spherical energy shield that absorbed most of the damage.. the moment she took down her shield though, the Water Mask and the Lightning Mask were on either side of her.
