Hope you like this! I intend it to be longer. Yes, I know, the Prologue is quite short, I'm sorry... :D

"Nara Shikamaru."

"Troublesome."

"Yamato."

"Yo!"

"Haruno Sakura."

"Shannaro!"

"Hatake Kakashi?"

No answer.

"Hatake Kakashi?"

Still no answer.

"Eh, he'll come eventually... Sai."

"Present."

The said brunette whipped a scroll out and laid it on the ground. He looked at the blond who had been calling out the names, and waited.

"Oh, yes. Start with the normal stuff. I, Naruto Uzumaki, Rokudaime, blah blah blah, and ask for Gaara to come in front of the Hokage tower immediately." Right that moment he felt a brush of sand go past him and start to build up into a person right behind him.

"No need for that." the redhead spoke, after clearing his throat.

Soon, they were all squeezed into the tiny amount of space the Hokage office had free - as you may have guessed, Naruto was always delaying paperwork way too long and it started to stack up. Naruto was squeezed between all of the others, in the middle. Gaara was exactly in front of him, Sakura and Yamato to his left, Sai and Shikamaru to his right. The blonde was looking at all of them with concern - an emotion you didn't see every day on his figure, and everyone - even Sai - had the same feeling painted on their faces.

"We have gone through six years of war." His voice was cracking, in his attempt of showing no emotion. "We are fighting to survive, each and every of us, and it's clear that if we don't do something now, one of The Five Great Shinobi Countries is going to be wiped out." Naruto stopped for a second, and then motioned to the pineapple-top, signing him to take the word. "Shikamaru."

"Hokage-sama," he bowed his head a little in respect, and then raised his eyes looking straight at the blond. He only stared back at his Chief Strategist. "Space-Time Alteration Technique is the only chance we've got left. However, supposing we have a modifiable one-timeline Universe, that implies that there are very few actions we can do to modify the past, without creating a paradox and, therefore, erasing the whole Universe."

By this point, the young Naruto would have been staring blankly at Shikamaru. Now, he was reanalyzing everything one more time by himself. "Shikamaru, my technique isn't nearly half complete. It's way too risky."

"I know. We have twenty-seven hours and forty-three minutes until the earliest time possible for another attack to be landed on Konoha. Since the preparation is tedious, I think you have a little more than twenty-three hours to complete it."

Naruto looked down. He had twenty-three hours, but he was using one thousand Shadow Clones in order to speed up the training process. That being taken in consideration...

"Twenty three thousand hours of practice should be enough." Everybody raised their eyes, to see the silver haired jounin looking down at them with a fake apologetic face. "Sorry, sorry, a dog snatched..."

"Cut it! We are dealing with an emergency here, you don't need your alarm clock to wake up!" Sakura and Naruto shouted at him.

Kakashi sat next to Naruto, with his legs tucked one under the other.

"Gaara, you have the same elemental affinity as Naruto. While he will be performing the main jutsu, you will maintain the anchors in time." Shikamaru took out a cigarette from his back pocket; when the war had started he picked up smoking again. He lit it and let it hang at the left side at his mouth. "We will divide again in teams. Team One. I, Shikamaru Nara, Naruto Uzumaki, Sai. Team Two. Kakashi Hatake, Sakura Haruno, Yamato, Gaara."

Everybody nodded, stood up, and left the room silently, towards the training grounds.

The Space Time Alteration Technique will be called Jikuu Henshitsu no Jutsu (did I get it right? correct me if I don't, please). Hope you liked this!
