OOO: Kamen Rider of Konoha
A Naruto and Kamen Rider OOO Crossover

(A/N: Before we start this, I think that people should know that I will not be showing much from the Naruto series. The reason is that I hardly know anything about it and as such I will only be going off basic knowledge and a little bit of knowledge from a couple of other fanfics that are crossovers like this one. Now that I have that out of the way; I may not think OOO is the coolest rider and I may not be a big fan of Naruto but from what I've seen this plotline is very popular and I figured I would give it a shot, please do not hate me. Also, I am not very good at third person so please feel free to point out what I can improve upon. I also know that describing things like the riders' armors is hard for me so I will not try, if you need help picturing it then you should look them up on google images or something.)

Chapter 1:

Things Go Horribly Wrong

For most people, death is the only way into hell. For Naruto Uzumaki, he was born there. When his village was attacked by the 9-tailed fox, also known as the kyuubi, the fourth hokage sealed it inside of Naruto in the hopes of having the village think that he was a hero. Instead most people felt that Naruto was just the kyuubi in a new form and tried to kill him. Luckily, he had his three triplet sisters to back him up and a few people who actually tried to be nice to him like the owners of the Ichiriku ramen stand and one of his teachers Iruka. Of course those were some of the only perks he had in life so he was still beaten, pounded, and yelled at all the time.

Even so, he is now a genin and part of shinobi team 7 along with Sakura Haruno, a former childhood crush who he now knows despises him; and Sasuke Uchia, a stuck up bastard who has most of the civilian council as well as Sakura behind him since he is the last of his clan. Their sensei is Kakashi, a man who always has his face hidden behind a mask and his eye is covered by his head-band. Kakashi always favored Sasuke and Sakura over Naruto because the kyuubi killed his sensei. He once even put a kunai through Naruto's shoulder and then claimed that he attacked first! Luckily he was found to be lying on that one.

Naruto was thinking about all this but was brought out of it by the huge sword that flew at him before he ducked and it lodged itself in a tree. He and the others had been given a C-Rank mission to escort a bridge builder to his home in the land of the waves, which became an A-Rank mission when a pair of missing nin called The Demon Brothers attacked. The worker then explained that his home was being sucked dry by a corrupt businessman named Gato and he was supposed to build a bridge to give people another place to go for their needs. After some debate, they decided to go on and finish it. Now they were being attacked by Zabuza, the demon of the mists.

"You're fast kid. I gotta admit I'm impressed." He said. He then made a water clone and sent it after Tanzuna, the builder. As the clone was about to attack, Sakura ran and left Tanzuna just standing there, frozen in fear. Naruto dodged the real Zabuza's strike and then tackled Tanzuna just as the clone hit where he had been standing a second earlier.

"Nice one, it seems you actually have the right stuff to be a ninja. Unlike your team mates." He said with a smirk before Kakashi sent him up in the air. Sasuke then launched a giant fireball up at him but Zabuza deflected it at Kakashi.

What happened next took Naruto completely by surprise. One minute he's standing a few feet back from Kakashi, the next he's standing in the path of and getting hit by the fireball! Not only that, but Zabuza is coming down with his sword ready to strike!

"What the-! I can't stop! That son of a-!" Zabuza thought as he cut Naruto. He saw the boy fall over the edge of the bridge and into the rushing waters of the river below.

"Rest in peace now, sensei..."Kakashi muttered under his breath before he sees Zabuza attacking in a berzerker state.

Meanwhile, Naruto is floating down the river and wakes up in a cave of some kind. He checks himself over and finds that most of his major injuries have healed.

"Whew, thanks Kyuu." He said.

"Anytime Naruto, I'm glad I could help."A voice in his head replies. That's right, Naruto knows about the Kyuubi. She revealed herself when Naruto was 5 and he somehow entered his mindscape. Yes, the Kyuubi is a girl; she hates the fact that most people instantly assumed that she was male when she attacked after being provoked by a certain well known snake. They've become good friends and Kyuu's advice has saved his hide more times than he can count.

"So where are we?" Naruto asked, Kyuu answered that she didn't know. Then Naruto noticed a large stone door. On the other side he could hear a sound similar to that of falling coins. He walked over and tried to open it, only to receive a powerful shock.

"YEOW! Hey Kyuu, any idea what's in there?" He asked.

"Whatever it is, it seems to be giving off a kind of electric barrier. You'll have to break through to find out." Kyuu replied. Naruto then used his shadow clone jutsu and made 10 clones, all of which attacked at once, shattering the barrier.

"Nice one, now to go inside!" He exclaimed as he dispelled his clones and opened the door. Inside was a chamber filled with large grey metal coins. Each coin had an animal on one side, while there was a large X on the other.

Just as Naruto was putting down the coin, it fell out of his hands and rolled. He chased after it until it stopped when it hit the side of a stone coffin. The coffin was relatively large and had two things on top of it. One was a rectangle-shaped thing with three slots in it; and the other was gray, green, and made of metal with a sphere on it.

"Oh my Kami…Naruto, do you know what you've just found?!" Kyuu asked in a shocked tone.

"Sorry Kyuu, you're gonna have to fill me in here." Naruto replied.

"These objects contain great power, you should open the coffin."

"How do I do that?"

"Take four of the coins, then put three into the rectangle one and one into the other. I think that if you twist the knob on the spere one then you'll be able to turn the rectangle one and open it."

Naruto did as she suggested and found that she had been right as he opened the coffin and was bathed in an aurora-like light. He screamed in agony as his bodt began to change. That was the last thing he knew before he blacked out.

"Get ready Konoha Village..." Kyuu thought with a smirk, "The new Naruto is going to knock you flat!"
