Konoha Gakuen: Rider Warz

(Summary: Monsters are loose all over the world and only one breed of warriors can stop them. They are called Kamen Riders. Summary: I don't own Naruto or any of the Kamen Rider franchise, ok?)

Chapter 1: I Will Transform

Fifty years ago, monsters appeared out of nowhere and started terrorizing the innocents. It didn't matter if they were Fangires, Imagins, Worms or were called by any other names, these beasts plunged the world into a new age of darkness.

But at the same time, a new breed of mysterious yet powerful masked warriors also appeared to combat their menace. These warriors are called Kamen Riders and this is their story.

"Aww man... Looks like I'm lost again." A lankily built figure grumbles from atop his dirt bike which was painted bright orange with black flames and had a large knapsack strapped to the back. The rider himself had on a tinted motorcyle helmet with the same bright orange/black flames color scheme as his motorcycle and wore an orange jumpsuit with black stripes along the arms and the legs as well as black/orange hiking boots.

"Why the hell did they have to put the damned school out here in the middle of nowhere?" The figure mutters as he reaches up and removes his helmet, revealing a ruggedly handsome looking teenage boy with blonde hair, blue eyes and whisker-like marks on both cheeks.

The boy's name is Uzumaki Naruto. An orphan who had been raised by an old family friend named Sarutobi Hiruzen. Naruto's parents were lost and presumed KIA in the great Rider War 14 years ago and Sarutobi had adopted and raised him as if he was his own grandson.

Now 15 years old, Naruto was ready to follow in the footsteps of his parents and become a full fledged rider himself.

Assuming he can find the place that is.

The blonde teen looks around and tries to get his bearings. His surrogate grandfather had provided him directions to the school which was actually a secret training facility of the next generation of riders. He followed the directions he was was given till he turned right towards an alleyway in a nondescript part of town and ended up in a dense and creepy looking forest with nothing but an old faded foot path to follow.

"Stupid Jiisan... Couldn't he have given me more specific instructions on how to get to the school? Honestly..." Naruto mutters as he studies the piece of paper which contain the directions to the school again. But he suddenly looks up as the sounds of a battle nearby reaches his ears.

He frowns to himself as he fingers a plain black box the size of a slightly larger deck of playing cards inside a pocket in his jumpsuit. This was his henshin device and while he was only able to use it to transform into an ordinary, blank slate rider strong enough to beat muggers and defend himself from the occasional monsters, it is a cherished memento from his parents and he wouldn't trade it for anything else.

Investigating the disturbance and witnesses what seems to be a battle between a staff wielding kamen rider in a blue-black armor with fins on his forearms, the back of both legs and on top of his helmet and a much larger kamen rider in orange armor and black tiger stripes with claws in place of hands. And from the looks of it, the blue-black kamen rider seemed to be having a lot of difficulty against his opponent's brutal attacks.

To Naruto though, something seemed definitely off about the tiger themed rider and upon closer scrutiny, the blonde teenager realized why.

The savage rider's armor didn't make him look animalistic, it was his actual body. The way the sleek muscles quivered with exertion and the powerful jaw muscles with sharp teeth clench and move made him look too oraganic. Aside from those factors, there was also the distinct absence of any kind of transformation anywhere in the tiger-like rider's body.

As Naruto debated on what to do, he overhears their conversation in the middle of their fight.

"Why are you doing this Mizuki? Why have you willingly chosen to become the very thing we've been trained to defeat and destroy?" The fish themed rider asked as he held back his opponent's attack with his staff.

"Ain't it obvious Iruka? This world only belongs to the strong like the monsters." The monstrous being identified as Mizuki answered." And thanks to the power they gave me, I get to be a part of that world."

"But what about the lives they've ruined? All the friends we've lost against them? Don't their sacrifice mean anything to you?" The one called Iruka persisted.

Mizuki barks out in laughter. "Are you kidding me? What have I gotten inreturn of my years of service as a rider? Absolutely NOTHING! The monsters had the right idea when they invaded our world. Humans are weak, a waste of oxygen and space. And I have absolutely no attachment to this world so why should I care if the entire human race is exterminated? I'm powerful and immortal and that's all that matters to me now."

The last callous statement from Mizuki clinched it for Naruto. Being raised and taught the way he was, it was only natural that he hated traitors. In the words of one of his tutors, 'Those who don't follow the rules are trash. But those who abandon their comrades are even bigger trash'. And Mizuki is one of the biggest there is.

Looking at his henshin device, Naruto didn't really know how much help he could be. But he'd be damned if he was gonna let Mizuki get away like this.

"Right then." Naruto said to himself resolutely as he willed his henshin belt to existence around his waist. "Henshin." As he uttered the command phrase, he slides the plain black rectangle to the empty slot on his henshin belt's buckle and transforms into plain grey, lightly armored kamen rider with blank visor card reader on his left arm and a helmet with a vaguely vulpine design.

"Arghhh!" Naruto looks up and sees that Mizuki had sent Iruka flying back with a slashing attack with his claws as sparks flew from the blue clad rider's armor. The blonde knew he had to move quickly or else, the man was finished. He opens his card reader and takes out one of the few cards he had from his advent deck on his deck and places it into the Blank Visor before closing it up.

"Trick Vent." A computerized voice spoke as four perfect copies of Naruto appears besides him and charges at Mizuki to attack him. The beastly rider looked caught off guard by the surprise attack, enabling the real Naruto to hurry towards Iruka to assist him.

"You alright mister?" Naruto asks as he helps the blue-black rider get back up to his feet.

"I'm ok. Thanks for the assist." Iruka said gratefully.

"Don't thank me yet. Those clones I sent won't last very long so you better come up with a way to beat this guy before then." Naruto said. "The name's Uzumaki Naruto by the way."

"Naruto?" Iruka repeated. "You're the one that the Headmaster sent me to accompany to the school because these woods are very easy to get lost in."

"So I noticed." Naruto said dryly before one of his clones suddenly fly past them and disappears. "Dammit. He's already beaten them." He curses as he turns to face an emerging Mizuki.

"Who the hell are you to stick your nose in my business, brat? And you're just a blank so what makes you think you even stand a chance against me?" Mizuki growls.

Instead of answering, Naruto opens his Blank Visor again, takes out another card from his deck and slides it into his reader before closing it and charging forward. With an announcement of "Sword Vent", a sword resembling a kukri blade appears in Naruto's hand and he uses it to attack Mizuki.

Mizuki blocks the attack and tries to slash at Naruto but the young rider manages to evade Mizuki's claws and fires off a quick roundhouse kick to the traitor's midsection and following it up with headstrike with the pommel of his blade. Unfortunately, Mizuki's body was as hard as a rock so he was unaffected by the attack and even managed to clip Naruto with a backhand which sent him flying back.

Undaunted by the strength of his opponent, Naruto recovers quickly and charges forward again. By accident or sheer luck, Naruto ducks under Mizuki's counterattack, swipes at him with his blade, and manages to blind his left eye with the attack.

"ARGGGHHHH! My eye!" Mizuki screams in pain as he clutches at his eye. "You'll pay for that with your life brat!" Moving faster then it was thought possible, Mizuki was suddenly in front of Naruto and savagely batters him before sending the boy flying back and undoing his transformation. Iruka tries to intervene but was also sent crashing against the trees.

"You're finished brat. Ain't nobody who's gonna help you now. And once I'm done with you, it'll be Iruka's turn." Mizuki said evily as he slowly walks towards Naruto who coughs out blood and struggles to get back up to his feet but fails.

"Dammit... It can't end here. I can't die in a place like this at the hands of someone like Mizuki." Naruto thought to himself as Mizuki stops in front of him and raises his claw.

"Now you die." Mizuki and slashes down. But before he can connect, an orange blur intercepts the attack and knocks him away. Recovering quickly, the traitor looks at who interfered and was surprised to see another monster, this one resembling a large cybernetic nine tailed fox, standing protectively in front of the brat and growling at him.

"What the hell do you think you're doing?" Mizuki asks the fox. "That brat is the enemy and not me. Out of my way!" When the fox doesn't move from his spot in front of Naruto, Mizuki attacks again and appears to wound the fox with a swipe of his claw but is forced to take cover when the fox retaliates by spitting out a number of fireballs at him.

For his part, Naruto couldn't believe what he was seeing. A monster was defending a human like him. But then he remembers the words his surrogate grandfather said to him a long time ago.

(Flashback)

"Naruto Kun. While it's true that Riders are the only ones who can defeat the monsters that threaten humanity, you also have to remember that not all monsters wish for our world's destruction. Where do you think our powers as Kamen Riders come from? One day, you will unlock the true potential of your device and that is when your own destiny will unfold."

(Flashback End)

"Is this what you meant Jiisan?" Naruto thought to himself as he watched the cybernetic fox look around it's surroundings for a sign of Mizuki. The blonde's eyes then travels to the furrows made by Mizuki's claws on the fox's back. A black, viscous substance is seen oozing from the damage and the way that the fox was having difficulty with it's movements suggested that it was affecting it. "Is this fox really saving me from Mizuki?"

A bellow of rage snaps Naruto out of his musings. He looks up just in time to see Mizuki almost on top of him with his claws raised. But once again, the cybernetic fox rams into the traitor and sends him flying back towards the woods.

"YOU BLOODY TRAITOR!" Mizuki screams as he comes out of the treeline where he landed. "Fine! If you're going to protect that brat then you're joining in oblivion!" The fox bristles and prepares itself for battle but a hand on it's haunches stops it. The fox looks up and sees Naruto shakily stand besides it, glaring at Mizuki.

"That's enough outta you Mizuki. The only traitor I see around here is you!" Naruto stated to the beastly rider. He then looks at the cybernetic nine tailed fox besides him. "You don't have to fight him on your own anymore my friend. What do you say we do this together?" Naruto asks with a foxy smile as he takes out an empty card from his blank advent deck and shows it to the fox. The fox eyes widens and nods in understanding before it's body dissolves into a shower of light which transfers to the empty card. A moment later, a picture of the cybernetic nine tailed fox appears on the card with it's name below.

"Let's go, Kyuukiri." Naruto mutters as a stylized fox head appears on the case of his advent deck after inserting the monster's card in it. "Henshin." The blonde once again utters the command phrase and inserts his new advent deck case into his transformation belt, transforming him into a kamen rider.

The difference this time, was he now wore rusty red armor with flame-like designs which covered his upper torso and shoulders, right forearm and shins. His helmet as well as the new Kyuu Visor on his left arm now resembled a smiling fox with slits for eyes and whisker-like protrusions. And attached to the helmet are nine spearheaded dreadlocks.

"Alright. Let's try this again, shall we?" Naruto said as he crooked a finger at Mizuki, inviting him to attack again. The traitor needed no other invitation and attacks the new rider.

This time however, Naruto was ready for him.

The fox-themed rider sidesteps the first attack and rocks Mizuki with a right cross and backhands him with the same hand. He then grabs Mizuki by the back of the head and punishes him with knees to the body from the clinch before sending the traitor flying back with a front kick. But Mizuki quickly recovers and charges at him once agaim.

"You're pretty resilent." Naruto comments as he effortlessly dodges or blocks Mizuki's subsequent attacks and counters them with vicious attacks of his own. "That's good coz it'll make kicking your ass even more satisfying."

Mizuki then tries to confuse Naruto by jumping from treeline to treeline to make it difficult for the young rider to predict where he will attack next. But Naruto simply takes out a card from his deck and inserts it into his Kyuu Visor. "Strike Vent." A mechanical voice from the Kyuu Visor announces as the speaheaded dreadlocks on Naruto's head comes alive and starts attacking Mizuki everytime he comes close.

Mizuki skids back, his monstrous form cut up and smoking from the damage he has sustained so far. "Who the hell are you and what right does a brat like you have interfering in my affairs?" He snarls.

"My name is Uzumaki Naruto. But you know what? I can't keep calling myself by my own name in this cool new form of mine." Naruto said as he goes on a thinking pause before snapping his fingers. "I've got it! How about Kamen Rider Youko?"

"It doesn't matter what you call yourself! You're still a dead man as far as I'm concerned!" Mizuki growled as he attacks once again.

"You really are in a hurry to die aren't you?" Naruto mutters as he inserts a new card into the Kyuu Visor. "Unfortunately, my little friend ain't done with you yet."

"Advent." The newly named Kamen Rider Youko's contract beast Kyuukiri suddenly pounces at Mizuki from out of nowhere and starts viciously mauling him before tossing him up into the air.

"It can't end like this!" Mizuki screams as he rights himself in midair and starts gathering energy in his mouth. "I'm not going to let you ruin my ambition!"

"Unfortunately for you, it's the end of the road." Kamen Rider Youko said as he points to something behind the monster. Looking back, Mizuki sees his old friend Iruka in his rider form behind him with an arm raised and the fin in the arm glowing with energy.

"Goodbye Mizuki. Rider Slash!" Iruka said before cleaving his former friend in half. Mizuki screams in agony for a moment before he explodes, leaving a glowing orb which Kyuukiri greedily snatches up before he disappears as well.

"Whew." Iruka breaths a sigh of relief as he reverts back to his human form before looking at his fellow rider. "Thank you for the assist Uzumaki San."

Naruto also reverts back to his human form by removing the advent deck from his belt. "No problem. Like I said, I don't really like people who..." *Thud* Naruto doesn't get to finish his sentence as blackness envelopes him and he falls into unconsciousness.
