I do not own Kamen Rider or any other Anime or Games.


A lavender haired girl thought it was a nightmare. She was standing in the middle of a war zone as a battle commenced. She saw explosions ring out throughout the area as many people, wearing different types of suit and armor, were dropping dead one by one on both sides. As another set of explosions ran off and the smoke later cleared, she sees a figure.

She looked to her left and was a glowing figure cloaked in a pink light. He had green insect-like eyes, a white buckle on his belt with various insignias surrounding a red dot in the center.

"Decade…" she muttered, surprised that the name popped into her head.

She then turned a bit to her right, and saw an armored figure standing up. He was wearing a black armored body suit that had silver lines pointed inward on his chest, giving off the semblance of a ribcage. The same silver lines covered his wrists and ankles, and two more lines also were on the outer edges of his shoulder pads. A tattered scarf was draped around his neck. Numerous slots were wrapped around his chest and limbs, as if they were meant for something. But what the girl found to stand out the most was the silver helmet that looked like a skull, and strangely, a white fedora on top. Around his waist was a belt with a red mechanical buckle that had a slot that tilted diagonally.

"DECADE!" He roared as he charged at the glowing figure, with a black sword that had a skull on the guard raised. But as he was close, another explosion took place where he had stood. As the smoked settled, the skull wearing figure was struck down from behind. He had dropped onto his knees before falling face first onto the earth, the grip on his sword loosening.

The girl turned around and saw a similar figure to the glowing one. But this one had blue eyes, a black buckle, and a malicious black aura was coming off him.

"…Dark Decade…" She muttered again.

Both Decades looked at one another and drew their weapons, a sword whose guard resembled a book. They charged at one another, running past their fallen comrades. Their blades soon clashed, engulfing the battle field in a bright light.


*CLICK*

Was the sound being made from a pink camera in front of the local park's river. Holding the camera was a man in his teens. He has brown hair and purple eyes, he's got a magenta Twin Lens Reflex Camera around his neck along with an Mp3 player with some wireless headphones with the same color on him. He's also wearing a black coat with a magenta shirt and black pants. His name is Noel Inoue.

Not much is known about Noel, except the fact he's an orphan at age 10, with no memory past that age and his name was also one of the only things he remembered. When he was at least 14 and old enough to leave the orphanage, he traveled around Japan for a year before coming back to the town he lived in. He also loves to take pictures with his camera but they were not so and he loves listening to music on his Mp3 player.

Noel was about to leave the park, but he felt a tap on his shoulder. He turned to see a group of people, who looked ticked off for some reason. Noel pressed the pause button on his headphones and placed them off his head then around his neck.

"Can I help you?" Noel asked. The group took out distorted pictures and he immediately understood what that meant. He went to work at a photo studio a few months ago and he was surprised he wasn't fired.

"What the hell is this!?" the leader of the group asked. "We paid for good photos and all we get is this crap!"

"Sorry, but I really can't do much about it."

"Well, for one you can give us our money back." the second member said

"Why not talk to my boss about it then?"

"I rather talk to you first." the last one said while Noel took a few steps back.

"Sorry, I'm on a tight schedule." Noel said before running away, while placing his headphones on.

"Get him!" The leader ordered and soon the group ran after Noel.

"Man, these guys don't give up do they?" Noel mused while listening to the song 'Make History: Extended' and running away from the group. Noel noticed a narrow valley and saw an opportunity to turn his body 60 degrees and walked to the side to go through the narrow entrance to escape the group. Noel made it through and it gave him more of a head start, but the group tried to do the same thing, which they did and Noel saw a fence, he ran towards the fence before climbing it and going over.

"Get back here!" the leader yelled.

"No way, then I'd get beaten up." Noel remarked before running to the left. The group of people followed him and saw him turn at a corner.

They ran after him and made that turn, but Noel came out of another alley after hiding behind a garbage can.

Noel sighed before walking back to the studio.


Noel, with his headphones around his neck, just entered the studio called the Isao Studio.

"I'm back!" Noel said before closing the door.

"Welcome back, Noel." the said teen looked to see a female around his age with lavender hair that goes down to her neck and with two strands longer, red/violet eyes and she's wearing a purple turtleneck sweater, a black skirt and purple shoes.

"Hey Strea." Noel said to the girl, dubbed Strea. Personally, he thinks Strea is an odd name, but he's not complaining one bit. Strea is also a person with amnesia like Noel, she was found by him while he was on break.


(Flashback - 2 months ago)

Noel is lying down on a slope eating a burger, after he finished the burger he placed the wrapper in his pocket before taking up his camera, planning to take a few pictures of the area. He took a few good pictures, but he has no doubt that they will end up being bad, he then noticed something down by the river.

"Hm?" Noel zoomed in his camera to get a closer look and he sees a lavender haired girl on the ground washed up. "Okay, not everyday when you see a girl washed up by a river." Noel said before running down the slope and heading towards the girl to see if she's alright.

(Present)

After she obtained help, she was offered to stay here by the boss of the photo studio while she somehow got an interest in him in some way... ah well, he can figure that out later.

"Mr. Isao is waiting for you." Strea told him.

"Thanks." Noel said before walking towards the living room. He was then met with a man, who look like he just reached thirty with brown spiked hair and a goatee, also he's wearing a traditional Japanese shirt and a hakama. His name is Saburo Isao, but people either call him Isao or Mr. Isao.

"Oh, Noel-kun!" Isao noticed before Noel sat down at the table across him. "I heard that another group went after you because of your photos. And to be honest, I was worried." Isao really liked his pictures, he described them as creative and unique.

"Aw come on Mr. Isao, you've known me for a few months and you obviously know I can outsmart people chasing me." Noel said, recalling the times he's outsmarted people in a chase.

Isao just laughed heartily.

"HAHAHA! I guess you're right about that." Isao laughed.

'You guess?' Noel deadpanned in thought. "Honestly, I don't know what the problem is with my camera though. No matter how many tries it doesn't seem good." he said while tossing his camera a bit up and down.

"Noel I know you're a good kid and I know you need really need to do better at this, but don't let that get to you." Isao assured the teen. "Now why don't you take a break from shooting photos for people and practicing on getting your photos better? Strea could use a break too."

"Alright." Noel got up and left. "Thanks Gorilla!" he teased on that last part.

Isao went into comical tears.

"I KNOW YOU LIKE TEASING PEOPLE. BUT BEING CALLED GORILLA CAN HURT SOMETIMES EVEN IF I DO LOOK LIKE KONDO ISAO FROM GINTAMA!" Isao cried pretty loud while Noel snickered a bit.

"Whatever." Noel waved it off.


"Thanks for taking me on break Noel." Strea said while walking by his side at a park.

"Not a problem Strea." Noel said while listening 'Burn My Dread' on his player, but with the volume low enough to hear her. He then spotted a vending machine, being thirsty he decided to get a drink from the machine. Noel placed a few Yen in the Vending Machine and got a couple of sports drinks out for him and Strea.

"Thank you." Strea said taking the can before opening it.

Noel opened his before taking a sip of his drink.

"So what do ya want to do?" Noel asked.

"How about we go shopping!" Strea said before she held his arm. Noel felt something soft and he realized it was her big soft... wait! What in the world is he thinking, she may be cute and all but he barely knows her despite the fact he met her a couple of months ago.

"Can you please let go of my arm?" Noel asked after taking a sip of his drink.

"No way." Strea refused. Noel sighed before finishing his drink and managing to get his arm free then putting the can into a garbage bin.

But as soon as it hit the bottom, everything around him and Strea turned nighttime, which was weird because nighttime was supposed to be in another few hours.

"What the hell?" Noel wondered before his eyes became one unfamiliar man. He was in his early twenties wearing a turtleneck shirt, black jacket, gray pants, and black shoes. Oddly, the same camera that Noel has was around his neck.

"Yo, new Decade." the man said.

'Decade?' Noel thought while narrowing his eyes.

"And what do you want?" Strea stood behind Noel.

"My name is Tsukasa Kadoya. Or better known as...Kamen Rider Decade." The man answered.

"Kamen..." Noel started.

"... Rider?" Strea finished.

"Wait, that doesn't even answer my question. What do you want?" Noel said.

Tsukasa sighed in disappointment. "Seriously, I'm going to have to explain all this? Fine then."

The scene then changed. Instead of the park, the setting was replaced with 13 Earths around them.

"What?" Strea said.

These are the Kamen Rider worlds in this universe." Noel looked all around them before turning back to Tsukasa.

"And? There must be some reason you are showing this to us."

"Glad to see you get to the point. Yes, the reason i am showing you all these worlds are because of..." Tsukasa snapped his fingers, transporting everyone to a field. He then pointed behind the group.

"...Him." Everyone turned around, and they were surprised to see the new figure. He was an armored man colored in black and yellow. His helmet was of the same color, but with black vertical lines going down the headpiece, which had two blue insect-like eyes. He also had slanted black X across his chest. "Dark Decade." And behind Dark Decade was every single Dark Kamen Rider that had existed. "The Dark Riders are making a move, trying to conquer each world, each story, and transforming them into their own. And soon, this one." he explained.

"Can't you do something about this?" Strea questioned.

"Unfortunately, this Rider Universe is... special. To the point where I and the other riders of my Universe have no jurisdiction over. We have our own world to protect, just like you. But that doesn't mean we are unable to help. I can tell you right now that you have the biggest role to play." Tsukasa pointed at Noel.

"Why are you telling us all this? And why me?" Tsukasa gave a small laugh.

"Man, now I know how Wataru felt when he met me. It's because...well, you might not remember but...you are to unite all the Riders of this universe and stand against Dark Decade and his Riders; if not, then the world will be consumed in darkness and Dark Decade will create a new Rider War. So, for a good tip: Defeat Dark Decade as soon as possible, or a new Rider War will occur, and nothing good will ever come out of it." Tsukasa said coldly. Shocking them with the truth. Noel took this information slowly, trying to get a grasp of it.

"But...why me?" Noel asked. Tsukasa just laughed.

"It's because...you are this world's version of me. You are this Universe's Decade. And grab your Buckle and Cards, they all got an upgrade." Tsukasa explained before a bright light engulfed their surroundings and the group found themselves back at the park.

'Am I really this world's Decade?' Noel thought. Before he could think about it more, he noticed that some buildings began to dissolve, catching his and Strea's attention. But it was short lived as a Dimensional Rift appeared from nowhere and engulfed them both.

However, on the other side, Noel was all by himself, in the middle of an unfamiliar, empty city.

"Strea? Where are you!?" he called out. He then broke into a run to search for his friends.


(Meanwhile)

Strea was standing in the middle of town and people were panicking in the streets, and they figured out why: the buildings were dissolving just like the ones she saw.

"Gr aaagggghhh!" the cry of one man caught their attention. She turned to her left and saw the victim falling to the floor dead. A black humanoid creature holding a spear stained with blood stood over him. The denizens begun to run as similar monsters appeared and attacked them.

Strea ran for her life and managed to evade all of them along with with other people. But before she could get far, a new Dimensional Rift engulfed her, transporting them into a raining, warehouse-filled, area.

One of the denizens suddenly had two long fang-like objects embedded into his neck as he quickly was drained of color, becoming a clear husk. Upon witnessing this, everyone panicked once more and ran. However, more monsters appeared. They all had stained glass patterns on their body and seemed to be based off of animals. They started attacking the people fleeing, draining them of their life force. But Strea managed to escape them.

She ran through an alleyway to flee.

"Wait!" One of the monsters cried. But it was too late as they fell through another gray mirror, this one placing them in a city which seemed normal, until a building collapsed behind her. She turned around to see the culprit, but it was a gargantuan Lobster-like monster with insect wings.

Strea ran away for shelter until she noticed two items inside the wall's crevice. "That's..." Her mind flashed back to the dream she had with the two riders. She walked up and grabbed them. Upon closer inspection, the metal items were just like the one's Decade wore on his belt. It was the same white buckle with the insignias. But in her other hand was a metal booklet. On the cover was a black stripe the ran diagonally through a white background and a black binder. The booklet had a small gray cylinder on the side.

"From my dream...but why...?" She questioned herself.

"Hey! Strea!" A familiar voice cried.

Strea looked up to see Noel behind the other side of a Rift.

"Noel!" Strea ran over to her friend. "Are you okay?"

"I wouldn't say this is okay..." he said as he gestured to the Rift that contained him before he had a dumbfounded expression while staring behind her. She turned around but backed up when she was facing herself.

"Strea?" Noel questioned.

The doppelganger smiled before changing form. She briefly transmogrified into a green humanoid, insect-like, monster before changing their form once more as they appear to have molted. Her current appearances was now a colony of type of insect humanoid.

Noel was thinking about what to do before he remembered something as soon as he saw the items in her hands.

'Grab your buckle and Cards...They got an upgrade.'

"Strea!" Hand me those!" Noel gestured to the stuff that she's carrying.

Huh? But...they're..."

"Just give them to me!"

Strea hesitated at first, but thrust the items out to him through the mirror. They went through a remarkable transformation as they changed from being covered in dirt and broken to being in pristine condition.

But as soon as Noel had a grasp on both items, Strea was yanked back by one of the green insect monsters.

"Strea!" He cried out. He then looked to the items in his hands, then back to her.

Without a moment's hesitation, he snapped the buckle onto his waist. He opened the booklet and saw that it was a black metal card holder. He pulled out the card from the left side and strapped the booklet to the belt on his left side.

He held up the card and flipped it in his hand.

"Henshin!" Noel inserted the card into the driver and closed it.

"KAMEN RIDE: DECADE!"

Then the Rider Symbols appeared and turned to armor silhouettes. They merged with him and he was now donned in black and white armor with a black, slanted X across his chest. Then red plates emerged from the driver and flew back to his head, cracking the gray mirror in the process. Once they had done so, they became red but turned into black parts of his armor, other than his chest, into magenta and a yellow light appeared from the center bar. This is Kamen Rider Decade.

During the transformation process, Decade broke through the Dimensional Rift, shattering it. Strea noticed Decade before the monster, along with other ones that are called Worms, suddenly became blurry.

"They're fast." Decade mused before following them to another area. He kicked a Pupa Worm before taking out a card and placed it in his belt.

"KAMEN RIDE: KABUTO!"

Blue hexagons covered his body before Kabuto, in Rider Form, took his place. D-Kabuto noticed a Worm about to break a pillar down in attempts to squish him, D-Kabuto placed another card in the Driver before closing it.

"ATTACK RIDE: CLOCK UP!"

(In Clock Up)

D-Kabuto used his RideBooker in sword mode and shoved all the debris away with it before he started slashing the Worms relentlessly in the vital parts. D-Kabuto continued to slash them before he slashed the fourth one and stopped.

(Out of Clock Up)

The Worms exploded into green flames as D-Kabuto rubbed the blade before turning back into his original form.

"Noel!" Decade looked to see Strea running towards him.

"Strea, you alright?" Strea nodded before they heard the sound of someone coming his way.

One could have mistaken him for a robot due to how his suit is designed but the black bodysuit underneath said otherwise. The suit is mainly black and silver with a police officer motif in some way. He had a silver chest that mimicked muscles with a silver badge on the left breastplate, his left forearm carried silver device of some sort, his knees were protected in silver pads, and around his waist he wore a silver belt with a red battery gauge meaning its the suit's main source of power. Finally his helmet is black with two silver horns on his head, a silver mouthpiece, and had large rounded blue eyes. This is the mecha battle combat suit Generation-4 or otherwise known as G4 for short.

"So you're the new Decade huh?" G4 said before he placed the big metal thing onto the ground. "Let me test your strength." he said before charging.

"Fine by me." Decade shrugged before charging in while Strea went to watch at a safe spot.

Decade threw the first punch but G4 blocked the punch and the latter made an attempt to punch his chest, but Decade deflected it while he felt a little bit of pain from it, meaning that G4 must be a tough opponent. The two traded blows before G4 punched Decade in the face and kicked his chest, which made him fly away a bit before safely landed. G4 went to the big metal thing and held it above his right shoulder then it was revealed to be a rocket launcher called the Gigant.

"You gotta be kidding me." Decade muttered before G4 launched a rocket. Decade dodged the rocket, which exploded on impact, before a second rocket was heading towards him, Decade grabbed a card and placed it in his belt real quick but the rocket landed on him, seemingly killed the Rider.

"Noel!" Strea cried out, fearing that he's dead.

G4 scoffed before...

"KAMEN RIDE: AGITO!"

Decade jumped out of the explosion, in the form of Kamen Rider Agito's Ground Form and landed on the ground.

"Sorry, but I die hard." D-Agito joked in a musingly way before placing another card in.

"FINAL ATTACK RIDE: A-A-AGITO!"

D-Agito's horns splitted as his symbol appeared under his feet and got absorbed. D-Agito jumped into the air before G4 could prepare the Gigant for another shot until he was kicked in the chest, making him fly away but G4 landed on his feet. Even G4 could feel a little bit of pain in his armor.

"Allow me to have a go at this." D-Agito, who just reverted back into Decade, and G4 looked to see another Rider.

He wore a silver/white bodysuit with black designs on the side of his torso. He wore black boots with magenta color scheme, black wrist bands, and his armor has black apple slices sticking out his chest and shoulders. His helmet is mainly black designed as flames with a magenta faceplate. This is Kamen Rider Jam.

"Very well." G4 said before leaving in a Dimensional Rift.

Jam looked at Decade before he took out a weapon that looks like a purple orange slice and a katana that doubled as a gun.

Decade took out a card and placed it in.

"ATTACK RIDE: SLASH!"

Decade charged at Jam with his Ride Booker in sword mode and the two engaged in a sword fight while Decade found some openings and slashed Jam with his blade making holograms with each swing, but had an effect on him. Jam blocked a slash with both of his swords and kicked Decade back before making an energy slash, which made Decade roll to the ground.

"In that case." Decade puts another card in the Driver.

"KAMEN RIDE: GAIM!"

An orange fell on Decade's head before it unfolded into Gaim's default form.

"ORANGE ARMS! HANAMICHI ON STAGE!"

"More of a reason to kill you!" Jam said before making his weapons into a Naginata. D-Gaim brought out the Daidaimaru and charged at the Dark Rider. D-Gaim played offense while Jam played on the defensive mode and the former swung his Daidaimaru at Jam, who was blocking his swings until D-Gaim found an opening and slashed Jam twice then kicked his chest hard, making him back off. D-Gaim placed a card into the Driver.

"ATTACK RIDE: DAIDAI ITTOU"

D-Gaim's weapon glowed before he ran at Jam and slashed him straight, making him groan in pain. D-Gaim jumped back for a moment before Jam slowly got back up.

"I am the Golden Fruit... I shall not let you win!" Jam declared before kicking his Naginata in the air and grabbing then 'slicing' the lock twice.

"DARKNESS AU LAIT!"

A giant dark apple appeared in front of Jam, he jabbed the Dark Daidaimaru into which sends it flying towards D-Gaim.

"I think not!" D-Gaim placed another card in his belt.

"ATTACK RIDE: FRUIT SHIELD!"

The orange armor covered D-Gaim's head and he spinned it around then headbutted the incoming apple, which was hard enough to send it flying back faster. The apple landed on Jam, making it explode and making him cry out in pain.

"Damn you..." Jam got up before...

"FINAL ATTACK RIDE: G-G-GAIM!"

Jam watched D-Gaim jump into the air and with orange energy around his foot then got into a sidekick position and he aimed his fiery foot at Jam then landed on his chest, making an explosion and another cry of pain from him.

D-Gaim reverted back to Decade and headed towards Strea.

"We need to leave now!" Decade said, earning a nod from her and reverted back to Noel before heading towards the studio.

"Not bad for your first fight." Tsukasa said, appearing out of nowhere.

"What are you doing here?" Noel asked.

"One, I came to drop this off for you." Tsukasa stepped aside to present the machine Decader. "Two, to let you know you are able to use the studio to travel to the other worlds,"

"Wait, what!?" Noel and Strea cried, but Tsukasa ignored them.

"And three, I'm going to distract the Dark Riders here while you guys leave."

"But I thought you said you had no jurisdiction here." Noel countered countered.

"I did say that. But I also said I was going to point you in the right direction. Just think of it like that. After you're gone, I'm gone." Tsukasa then got out his own Decadriver. "Now, watch how a pro does it." He snapped the driver on and got his card out. "Henshin!" He placed it in and quickly closed it.

"KAMEN RIDE: DECADE!"

Noel and Strea watched as Tsukasa transformed into another Decade.

"So this is where you went!" Jam exclaimed after he found them.

"Noel, Strea! Go now!" Decade said and the two nodded before entering the studio leaving him to fight against Jam.

at the studio, Noel and Strea sees Mr. Isao going through the news. Isao looked at Noel with a neutral face.

"You're back, that man, Tsukasa, told me everything." Isao explained.

"You're not surprised?" Strea asked.

"Well considering what's happening outside, Tsukasa told me about what you're supposed to do is the least of my worries." Isao said before going back to normal. "But don't worry! If you can save this world, just tell me what I can do to help."

"Thanks Mr. Isao." Noel said before heading to the chains before letting them down. Soon, a background of a city appeared and Noel went outside to see what's going on. As soon as he got out, he was in a police uniform and in another city, which he thinks it's Tokyo.

From the radio on his belt, spoke a voice "Calling everyone on patrol. An Unidentified Life Form has appeared at the north sector. Giving orders on the scene is a member from the police Counter Unidentified Life Form department. On scene, follow the orders of the member from the Counter Department. Be careful not to get close to the Unidentified Life Form. Try not to get hurt or into any accidents. This is all from police HQ."

Noel heard it then checked out his attire and was surprised that he's in a police uniform. He soon saw a couple of police cars passing by.


At the City Park a hermit crab monster was currently killing all SWAT team members. A detective with gray hair and blood red eyes got on the radio.

"Unidentified life form #7 confirmed! Kazuya, can you hear me!?" Nearby a young man driving the TryChaser 2000 and soon arrived at the location. He takes off his helmet, revealing a young man in late teens. He has short straight blue hair and blue eyes. This is Kazuya Minegishi..

"Naoya!" Yugi exclaimed before summoning a belt. The belt was silver, had multiple buttons on it, and a red gem in the center. This is the Arcle. He performed a hand movement and pressed the side of the belt.

"Henshin!"

The belt soon starting making a beeping noise as Kazuya's body was completely consumed by armor pieces. His chest had red armor, red shoulder guards, red anklets, and black tights, gold anklets around his legs, the Arcle, and a helmet that had red compound eyes, silver mouth piece, and a yellow horn. This is Kamen Rider Kuuga.

Kuuga charged and punched the monster. He was soon ready for combat.
