Summary: She had always been watching. She had seen wars, and death, and she had lost so much. After eighty years, everything was set. Now Naru Uchiha would finally have her revenge.
Black Zetsu advanced on Madara. The ten tails Jinchuriki hovered up in the sky laughing maniacally. He had done it. He had launched the infinite Tsukuyomi. Now all Black Zetsu needed to do was kill that miserable Uchiha and free his mother. As he slowly got closer, he began to feel power in the air, as well as a sense of something else… uneasiness perhaps?
Meanwhile, Sasuke, Sakura, Naruto, and Kakashi stood in relative safety inside of Susano'o. Each once could only stare up at the ten tails Jicnchuriki and wonder just what the hell they were going to do now.
Suddenly they saw Black Zetsu jump up behind Madara. They didn't know what the odd creature had in store, but the four knew it couldn't be good.
Black Zetsu could only smile as he appeared behind Madara. He brought his hand back and prepared to ram it into the man's heart, just before he could strike however a hand caught his. He looked down as he saw a feminine hand wrap around his wrist. Madara spun around and spotted the mysterious figure, and Black Zetsu close.
"What the hell is going on?" Madara asked.
Suddenly the figure shot it's hand out pressing it to Madara's chest.
"You were always such a foolish man." The woman stated and Madara's eyes widened in shock.
"Naru?" Madara croaked out in pure unrestrained surprise. This woman, this was his wife. He hadn't seen her in over eighty years, and yet… she looked the exact same, as she had all those years ago. She had long dark hair, her eyes were alight with her own Mangekyou Sharingan, two four sided stars, overlapping, in an inverted fashion forming an odd eight pronged object. Within those eyes, was nothing but fury, fury and rage.
"Foolish man." The woman stated. "Seal!"
Madara's and Black Zetsu's eyes widened in surprise as both of the woman's hands began to glow and suddenly they both felt their chakra evacuate their bodies.
Black Zetsu and Madara both began to fall to the earth as they felt their whole worlds begin to blacken. Meanwhile Naru began to laugh as she felt the Ten tails chakra rush into her body. Madara may have known a lot about the sage's seal, but what he didn't know was that Naru knew more. She understood the seal so well, that she could not only replicate it, but alter it as well.
As the power surged through her, she could only think back to the life she lived to lead her here. She remembered the age of war before the founding of the village's. She remembered her little sister… her loving little sister. She remembered falling in love and marry her hero, the clan leader Madara. And then she remembered the Senju… and how they had killed her little sister… and then what had Madara done? He surrendered to them that's what.
Naru refused… she fought against the choice, and for that she had been banished from the clan. Her own husband, her hero from childhood had cast her out, and then… a few years later…. He two, left the village.
For decades she had remained in the shadows, perfecting her abilities mastering her sealing powers, gain unparalleled mastery over her Sharingan, and she watched. She watched as her foolish husband, once again failed to defeat the First Hokage. She watched had he grew old and withered away. And she watched him, as he was manipulated by that black chakra being. She only wondered for a moment, when it had happened. When had her hero become such a fucking useless moron?
Finally she felt the power within her settle. She felt it stabilize, her improvements to the seal configuration the Madara had utilized, was able to ensure that she was capable of utilizing the ten tails abilities quite quickly and with ease.
With the power of the ten tails, now under her command, she could finally begin with her plans, but first...
Madara was lying on his side, he felt empty and he knew that his life would soon be over. Having the ten tails chakra, forcibly ripped from his body, had all but ensured his demise, barring some sort of miracle.
Suddenly he felt a presence standing over him. He glanced up just in time to see what was once his wife, bring her foot down onto his hands, crushing the bones within them.
"That's for ever trusting that Senju trash, you moron." Naru stated as she turned to face the remaining threats.
Meanwhile, Team seven could only stare in surprise as the woman whom had just mysteriously appeared, had kicked the shit out of Madara and the Black humanoid thing.
"Maybe she's on our side." Naruto stated, in his typical hopeful fashion.
"Well, you're the one who can sense negative emotion, what does it look like?" Kakashi inquired.
Naruto looked to focus for a moment before a bead of sweat ran down his cheek. "Oh crap. She's evil."
"How astute of you, little boy. Now if you don't mind… I need to kill you four and then get to the really enjoyable part, where I spend the foreseeable future, torching the reborn Senju." Naru informed them with a mad smile before dashing at them, ready to fight again.
