(This is my first Naruto fic, but I have been a fan for many years)
Itachi and Orichimaru meet for the final time before they attack Konoha with the Raikage and the remainder of the Akatsuki. "Orichimaru, is everything ready?"
"Yes. But what should we do about the thing that attacked me and Kabuto?"
"I'll have Raikage take care of him. If that fails, I'll finish him once and for all."
(Back in Konoha)
Tsunade is sitting in her office when a messenger bursts through her doors. "Hokage-sama," gasps the messenger, "an army is beginning to move towards Konoha. It should reach here within 12 hours." Tsunade immediately begins barking orders to all the shinobi.
"GET EMERGENCY SEALS IN PLACE! SECURE CIVILIANS IN THE EMERGENY DEN! WHERE THE HELL IS NARUTO AND KAKASHI?"
(Other side of village)
Naruto and Sasuke receive a message that they are required to drop whatever they were doing and meet the Hokage right away. Naruto and Sasuke immediately drop the bowls of ramen and rush towards the tower. They see that the entire village is in chaos as shinobi evacuate civilians and set up defense positions. When they get to the top of the tower they see hundreds of shinobi surrounding Konoha with scroll seals. They rush into Tsunade's office.
"Hokage, what's going on?" asks Sasuke.
"The enemy is moving. We need every available shinobi. Speaking of which, where the hell is Usuigi?"
"No one has seen him since the night before last," responded Sasuke. Naruto was shaking. He knew that this would be his first participation in defending the village since when he fought Gaara all those years ago.
"You better get prepared you two, this will get very messy," said a voice from behind. They see that it is Usuigi and Kakashi. Kakashi was wearing his usual shinobi outfit and Usuigi was wearing his shinobi outfit without the mask and had his billowing black cloak over it. Naruto noticed something in Usuigi's eyes. They seemed to have a deep hate in them barely covered by sanity. Another messenger comes bursting through the door. The hallway is filled with chaos and disorder.
"Hokage-sama, we have just received information that the Raikage has joined forces with Orichimaru and the Akatsuki." Tsunade couldn't take it anymore and shattered her desk to splinters with her brute force. Papers flew through the air as people blocked their faces from the flying debris in the air. Everyone heads out to the walls around Konoha and waits for the Hokage to make join them for the battle that would decide the future of Konoha.
Everyone sees the Kazekage and his shinobi approach the walls and join the Konoha shinobi on the walls. Gaara stood with Naruto and the Hokage on his other side.
"You ready?" asked Gaara.
"Hell yeah."
(I know it's short but there will be two more chapters after this with much to add)
