A/N: this is set during Naruto Shippuden before the Peini Arc...

Chapter 1

"Hey old man! One order of beef ramen please!" the well-known blonde shinobi, Naruto Uuzmaki, yelled out.

It was just a regular night for Naruto, and Naruto being Naruto, was doing his usual round of night ramen. And soon enough, the a steaming bowl of japanese noodle and broth was set in front of him. Naruto gave a satisfying sigh.

"Ittadakimasu!"

He was about to reach for the chopsticks when he notice his pink haired teammate come and sit next to him.

"Sakura-chan! I didn't know you were going to be here."

The pink-haired kunoichi gave a small smile. "Hey Naruto. Well, to tell you the truth, I didn't. But it's just that I got so hungry, and you of all people know that Ichiraku has the BEST ramen in the village. Oh, I'll have the miso ramen," she noticed the man waiting for her order.

Silence filled the air, along with the sounds of Naruto slurping his ramen. In mid-slurp, Naruto realized something.

"You know Sakura-chan….it's just us here at the ramen stand…."

Sakura gave her hyperactive blonde teammate a weary look. "And…?"

Naruto gave off a creepy grin. "Well, we, two people….two people happened to be a guy and a girl…..a guy and a girl who happen to be good friends and all….I'd say that this is a da-"

"NO I WOULDN'T CALL THIS A DATE YOU IDIOT!" Sakura yelled as she whacked Naruto over the head.

"Ittai!…ehehehe…s-sakura-chan I was just kidding!" Naruto put up his hands in defense. He looked over at Sakura who had steam sizzling out of her head as she ate her food. Naruto sweatdropped.

"We'll, no surprise to find you here Naruto."

Both teammates turned behind them to find Yamato, Kakashi, and Sai.

"Oh hey Kakashi-sensei, Yamato-taicho, and…..hm….funny…I don't believe we've met before," Naruto glowered at Sai.

Sai put on his fake smile, "Oh….well who could ever forget the guy who doesn't have any balls?"

"WHY YOU-"

Sakura quickly cut in before anything could happen. "Is there something you guys need?" she looked at Kakashi and Yamato. "It's strange for all of you guys to be here at the same time…"

Yamato's face was serious. "Tsunade-sama wants to see us," he said in a strange voice. Naruto stopped bickering at Sai while Sakura gave her full attention to the wood-wielding man. Even Kakashi had a serious look in his eye.

"Huh? A new mission?" Naruto asked.

"Not exactly," Kakashi said, "Strange things have been happening."

"What kind of strange things sensei?" Sakura asked.

Yamato spoke up. "Weird portals have been opening up in various places in Konoha, Suna, and all the other villages."

"Portals?" Sai asked.

A stress mark appeared on Naruto forehead. "YOU MEAN YOU DON'T KNOW WHAT THIS IS ABOUT EITHER? *SMACK* Ittai…."

"Naruto would you just shut up already!" Sakura had punched him on the head.

"Not only that…but strange monsters have been coming out from the portal," Kakashi added.

"Yamato-taicho, these monsters. What are they?" Sai asked.

"We don't know, but Tsunade-sama wants us to go to the office immediately," Yamato said as he and Kakashi turned to go to the Hokage tower.

######

At the Hokage's tower….

All the members of Rookie 9 including the sand siblingsand Sai were present, as well as Jiraiya, Kakashi, Yamato, Gai (Kurenai's on maternity leave XD). Everyone was here….but failed to notice a small boy in purple hiding in the back.

"Alright," Tsunade began, "I'm sure you all know what's been happening." Everyone nodded. "Strange things have been happening: portal-like actives, strange creatures coming out f them and attacking villages." Tsunade sat back on her chair. "Unfortunately, they've been happening more frequently."

Murmurs from Rookie 9 began. "Suna's Kazekage has agreed to help us investigate this new threat. You all are to investigate these portals and report back to me. Is that understood?"

"Hai Tsunade-sama."

"Kakashi, Yamato, Gai, and Jiraiya will be accompanying you guys as well. And even though I've appointed Shikamaru as your captain, these jounin have the authority to override anything. Is that clear?"

"Hai!"

"Good. Now I want to also emphasize that under NO circumstances, do I want ANY of you to interact with these portals. Since we still do not know their purpose or power, I want all of you to be very cautious of them."

"Hai!"

"Good. Now get going. You guys have...*sigh* yes Naruto?"

"Hey Granny-Tsunade….what role does that kid over there have?" Naruto pointed to the boy dressed in purple in the back. Everyone turned to look at him. Tsunade stood up and narrowed her eyes to look at the boy.

"I've never seen him before. How did he get in here?" Tsunade muttered quietly, "Grr…Izumo….Kotetsu….those good for nothing…"

Shizune sweatdropped, "ehhh….Tsunade-sama, would you like me to remove him?"

"I don't know how he got in. It's okay, one of you can take him out. He's probably lost or something. Anyway," all focus was back on Tsunade, "You all have tonight to pack. You leave-"

"They can't tonight."

All eyes were on the boy again. Kakashi and Yamato eyed the boy warily. Everyone stared at the boy. "Sin is coming," the boy said.

Naruto was the first to break out of it. He stomped over to the boy. "Listen here you…I don't care who you are, or how you got in here. But I've had just enough of your blabbering!" He went to punch the boy but was surprised when the punch went through him. Everyone gasped.

Sakura put up a hand signal. "Release!"

Nothing happened. The boy was still standing. Suddenly, his postured went stiff. "It's here!" and as soon as he said that he disappeared. Two ANBU members suddenly appeared…out of breath.

"Hokage-sama! Another portal has been opened!" one member panted. "And this time….a massive creature is within it!" the other member said.

"Evacuate the civilians! Hurry!" Tsunade ordered.

Everyone poofed away to the gates of Konohagakure.

######

Everyone couldn't speak. Right in front of them was a gargantuan whale-like beast, it's size rivaling Katsuya's, Manda's, and Gamabunta's size. Maybe even bigger.

"What the hell is that?" Shikamaru exclaimed, "Kiba?" "Don't look at me! It's not even an animal!" Kiba said as he tried to calm down Akamaru.

"Summoning Jutsu?" Yamato suggested. Kakashi shook his head, "It doesn't seem to talk, and I don't think anyone in the history of shinobis had the power to summon a beast like that."

"Whatever it is…we have to stop it," Shizune said.

"Right! Yamato, Gaara, Tenten, Sai! See if you can do any long range damage!" Tsunade ordered.

"Hai!"

"Oi! Granny, why can't we just go in there and attack him!" Naruto exclaimed.

Jiraiya put a hand on his student's shoulder, "Calm down, Naruto. How do you expect us to attack something close range when we don't even know our opponent?"

Sai took out a scroll with paintings of tigers on it. They soon came to life and headed towards the beast. Tenten took out a huge scroll as well and threw it at the beast, weapons hidden within it. Gaara made sand boulders that he launched at the beast, and Yamato summoned wood to appear and attack the beast.

The attacks failed as an unknown source deflected them. The lion paintings disintegrated, the sand rocks burst, and the weapons and wood just fell to the ground after hitting the barrier.

"Hyuuga!" Tsunade called out.

"Byakugan!" Hinata and Neji yelled. They both gasped at what they saw. "N-Neji! Do you see that?" Hinata stuttered. Neji cursed, "Shit! Tsunade-sama! There a strong force field that seems to be around it." He stopped short.

"What's wrong?" Tenten shouted.

"It….it doesn't seem to possess any Chakra!" Neji exclaimed.

Suddenly, the beast began to form an orb around it's mouth. Shikamaru's eyes widened. "Everyone move! It's going to attack!"

Four beams of light shot out of the orb in different directions. The light was blinding. Dust was kicked up.

Shikamaru took his arm away from his face and stood up carefully. He had dodged the beam of light, but just barely. He looked at where the light had hit and saw the damage it caused. "What a drag," he said to himself. He saw other members of Rookie 9 start appearing, unhurt thankfully.

"Is everyone okay?" Tsunade called out. Luckily all the civilians were in the safe-area underground. All of Konoha's shinobis including the ANBU were out.

"What was that?" Ino panted, shocked by the attack.

The beast gave out a cry, it's cry resonating and vibrating. Everyone covered their ears at the sound. It was horrifying!

'This could be bad,' Jiraiya thought to himself. He bit his thumb, drawing a bit of blood, before putting his palm on the gowned. "Summoning Jutsu!"

A large, rusty red colored toad appeared with Jiraiya on top.

"You better have a good reason for summoning me," Gamabunta croaked.

"Now, now, don't get all cranky with me Gamabunta, we have a serious problem on our hands," Jiraiya sternly told Gamabunta.

Gamabunta, who was surprised to hear the severity in his master's voice, felt the presence of a strong and large enemy. He turned to the beast and his eyes widened. "Jiraiya, you can't possibly be wanting me to fight that."

Jiraiya's frown increased. "What do you mean?"

"This isn't an ordinary beast Lady-Tsunade. It's powers are no match for even the mighty tailed demons," Katsuya, who was summoned by Tsunade without Jiraiya noticing, told Tsunade.

Tsunade's eyes widened with fear. "Then…what are…what are we suppose to do?"

The beast gave another cry, and turned it's attention to the shinobi who were posed and ready to fight. Everyone got a chill of fear as they saw all the beady eyes that were towards the front part of the mouth. Before anyone else could attack, everything started to go fuzzy and distorted, as if something was sucking the whole place to another dimension.

Naruto clenched his fist. "Well I'm not gonna just stand here and do nothing. I'mma take this thing down!" He rushed towards the beast.

"Naruto wait!" Tsunade cried out.

The rest of Rookie 9 plus Sai and the sand siblings chased after their blonde-haired friend in an attempt to save him.

Naruto ran at the beast, forming hand signs. "Shadow Clone Jutsu!" A clone appeared and immediately started to form a rasengan. Naruto jumped up.

"RASENGAN!"

A bright light filled his vision.

"NARUTO!"

######

"Huh?"

Naruto found himself standing in the middle of what seemed to be a road, people running away from something. It was chaos. It was nighttime, buildings were damaged, smoking, on fire.

"Where am I?" Naruto looked around, hoping to see something familiar. He soon was bumped and pushed by people trying to get past him.

"What? Hey! Watch it!" Naruto tried to avoid getting pushed.

Suddenly, everything stopped. It was dead silent. Naruto looked around himself. "What the?" he turned to find the same boy in purple. He stared at the boy. Then recognition flickered in his eyes. "YOU," he growled menacingly. He began to advance on the boy. "What did you-"

"It begins."

Naruto gave a puzzling look, "Huh?"

Then he disappeared and time was normal again. Naruto's eyes widened. "What the hell just happened?" He spotted two figures at the end of the road, going in the direction everyone was running away from. 'Maybe they can give me answers,' Naruto thought to himself as he tried to follow them.

######

Tidus runs down the street where he meets up with Auron again. "Hey, not this way!" he said to the older man.

"Look," Auron said as he gestured towards a huge floating ball of water that's above Zanarkand. Tidus gasped. "We called it 'Sin'" Auron explained.

Tidus looked at him, "Sin?"

Tentacles smash out of a nearbye building. Hundreds of small pods eject from the tentacles, landing on the ground. They turn into small bug creatures which surround Tidus in a demi-circle. He aimlessly tries to fight them off with his hands, but eventually falls backwards

"Take it." Tidus sees a sword that Auron offers him. He takes it and holds it high in the air, before nearly dropping it. "A gift from Jecht," Auron added.

Tidus looked at Auron with surprise. "My old man?" Tidus moves forward, swinging the blade. The bug-creatures move backwards. Tidus falls backwards onto and stands up again.

"I hope you know how to use it," Auron said to him before getting into a fighting stance.

The battle begins. They cut some of the bugs, but only more drop to fill in the gaps.

"These ones don't matter. We cut through!" Auron said to Tidus.

They continue killing the bugs and again, more bugs replace them. Slowly, they started making their way through. They were suddenly surrounded by the bugs.

"Don't bother going after all of them. Cut the ones that matter and run!" Auron instructed the younger boy.

They fought more bugs and were able to make a break through, more bugs falling behind them. A loud noise occurs. Tidus looks at Auron, who begins to run to the noise. Tidus follows. They come face to face with the big tentacle monster, surrounded by a few of the bugs from before. Battle begins with Sinspawn Ammes.

######

"Crap! Where did all of you come from?" Naruto exclaimed as he tried avoiding the bugs. One of the bugs spat small beams at Naruto, who easily dodged it. He couldn't get through. And if he couldn't get through, he wouldn't be able to find those two people. He smirked.

"Well…if that's the way you want it. Shadow Clone Jutsu!" millions of Naruto clones appeared and began making a pathway for the real Naruto, killing and destroying bugs.

Naruto kept running and stopped when he spotted the two people he was looking for. He was about to head for them when he saw the big tentacle monster. "What the hell?" He continued running towards them, determined to help them out.

######

Tidus and Auron were a little worn out from the sinspawn attacking them. They've defeated all the tentacles but one, which seemed to be the main one. Tidus was about to use his overdrive attack when a shout came out of no where.

"RASENGAN!"

A bright blue ball was shoved into the monster. He exploded before going translucent and bursting into pyreflies.

"Huh?" Tidus looked at Naruto. "Who are you?" He then noticed that Auron was running up ahead. He ran to catch up with him.

"Hey! A thank you would be nice you jerk!" Naruto shouted after Tidus and ran after him as well.

Tidus saw Auron had stopped running. "Auron! Let's get out of here!" Naruto had caught up as well.

"We're expected," Auron told him. Tidus just gave the man a confused look. Suddenly, Auron began to run again, Naruto hot on his heels. 'If I'm gonna survive this, I need to stick with them,' Naruto thought.

"Hey! Gimme a break man!" Tidus exclaimed as he followed the two.

The trio appear at a bridge, where stationary pods suddenly turned into the bugs. They all attacked the bugs, but others just filled in the gaps. They were completely surrounded, with an infinite number of bugs around them.

"Hmph, this could be bad," Auron said. He looked around until he spotted a piece of machinery. "That! Knock it down!"

"What?" Tidus exclaimed.

"Trust me, you'll see."

"But how? We can't risk being vulnerable to these things!" Tidus cried.

"No problem!" Naruto reassured the two men. "Shadow Clone Jutsu!" Once more, a multitude of Narutos appeared and started attacking the bugs. "I'll take care of these buggers for you, and you guys take care of that."

"Hmph," Auron said and began hacking at the machinery with Tidus. The more they hit it, the more it crackles with energy. Eventually, it explodes. It falls off the bridge, creating a massive explosion. All the bugs are destroyed. The bridge itself begins to blow up.

"Go!" Auron yelled.

They continue to run, avoiding the bridge which is blowing up. Tidus makes a huge leap and grabs onto the edge of a broken part of the road, which is diagonally facing upward. He hangs onto the ledge. Auron walks to the edge, standing above Tidus' hands.

"What the hell is happening!" Naruto yelled as he was sucked into the vortex.

Auron looks at the ball which contained Sin. "You are sure?" he asked. Auron looks back down at Tidus. "This is it." He leans down to pick Tidus up by the collar of his shirt. "This is your story….it all begins here."

Everything went white.

A/N:So what did you guys think? I'm sorry if it was sloppy. I just wanted the first chapter up. Please REVIEW. It would mean a lot to me!
