Author's Note: (18/2/2016) was the day I published this. When I babbled on my own.

(21/8/2016) I have a beta reader now. AND SHE IS SO INCREDIBLY GREAT AND NICE. Thank you kindly for your inputs and your works Koukaku. I'm sorry for assuming your gender. English is not my mother tongue, so spelling and grammar errors are all mine. It would be wonderful if you point them out through reviews or private messages. I won't say flame is welcomed though. My motivation will drop faster than your screaming speed when you see a giant centipede.

It's very clear that Naruto belongs to Kishimoto Masashi and those I don't know. I make no profit from this. I wish, though. Look how much E.L James' paid. Thank you for reading.

Uchiha Izuna knows for certain something's wrong when he sees his opponent's sclera turning into a dark grey color. He's quite certain that Tobirama does not come from a well known clan located in the Land of Rain. Or maybe he does have relations and now the signs finally show up. 'Bastard' will be used more often in his insults then. But surely those people from that clan do not have pale flesh on their face visibly cracked up like some sort of broken glass mask, before everything turns quickly back to normal.

And their previous taunting is replaced with a strange silence. Not mocking. Not calculating.

Bad signs.

That means more concentration and no mistakes. Those changes can't possibly promise anything good. (Tobirama may as well turn out to be the demon Izuna secretly thinks he is and Izuna won't be surprised—the cunning and merciless demon who haunts many of his clan members' nightmares.) He observes Tobirama closely, trying to make out any other significant changes. An unknown ninja can very well be a dangerous one.

They step back and raise their swords. Adrenaline laces with excitement and a little bit of fear. There's no turning back now. For their clans and brothers.

He's spent years training his eyes, though Izuna doesn't think much about how the fierce and sharp eyes start to lose their intensity, or why they show noticeable hesitance. Tobirama could be tricking him to then exploit his mistakes. He is ready to anticipate the other's moves, just one small wrong act and the Sharingan will see it to his advantage. Red meets red. He lunges forward.

Blades clash and water meets fire. Both are moving so fast that they look like a blur to the normal eye. A wrong calculation from Izuna's side ends with him being pushed much farther back.

He does not claim they are even now because he is having a hard time trying to keep up with Tobirama's speed. His opponent is definitely faster, although his blows are not as deadly as before. 'Too fast even for yourself, huh.' His eyes can still follow those movements, sure, but he isn't fast enough to do anything about it. He can't even land a single blow on that blasted Senju's clothes or that hideous blue armor while he himself receives quite the amount of small cuts. This is quite alarming. Here he thought Tobirama's immunity to illusion was shitty enough.

'So the strange change boosts up his speed. What else?' Izuna thinks warily, knowing he himself is at disadvantage. He can only hope that this doesn't apply to the elder Senju too because his brother and him are equal in strength, a boost up like this will be deadly. The wheels in Sharingan eyes once again spin rapidly. Slower or not, he will find another way. After all, no one is invincible.

Izuna does not see his opponent appear suddenly behind his back, but his instincts guide him and he lets himself thrust the blade backwards as fast as possible. He takes the chance to spin around, hoping to drag out the wound. His eyes allow him to see the details-

The uchigatana leaves a deep gash on the other's hand—the hand that holds the kunai high—Senju Tobirama does not bleed. 'Demon'.

A pair of pained and tired eyes is the last thing he sees. Then nothing.

"You know that it will cause a big wave in the timeline. Nothing will ever be the same again."

"Look around us." A bitter smile. "It sounds good to me."

"..."

"I am aware of the consequences."

"Are you ?"

"..."

"You could go yourself. That will ensure many people's existences."

"No. No, I can't. I must stay to control the seal's arrays. You know that nobody else can. Not even you."

"...Shouldn't what I am make me...unfit ?"

"Yes."

"Then why bother? There must be a better choice. I have-"

"There are. But you're chosen because you made the first mistake." Blood starts to slip through the bandage. "Or maybe because I'm dying and I don't have much time left. Please."

"You are willing to gamble this ?"

Haruno Sakura tries to sit up. Her body is trembling with exhaustion.

"Don't push yourself."

She just chuckles, it sounds like a wheezing cough. "The seal is Naruto's legacy. His last try to save everyone." She continues, "Yes, I'm gambling. If we succeed, then you can fix everything from the very start."

The seal takes up almost every surface of the small cave they're in. It's breathtakingly beautiful. It's genius.

"Sealing Arts: Super Mega Powerful Uzumaki Naruto and Friends' Space and Time Slicer Seal Of BackUp Plan." 'Such a ridiculous name.'

He can only watch her chakra being drained out through each hand seal from the empty center. She's still standing tall and proud after, though her panting makes it clear. He knows she's breathing her last.

With all of what is left of her strength, she leans forwards and 'pokes' his forehead.

"Punch the shit out of that little Zetsu fucker's face, yeah? And Madara's too if possible." The white light is blinding him but he still can hear a thud.

The last member of Team 7 has fallen.
