Toa Solaric: How is it going, everyone? Here is something that someone requested after talking about it for some time in the past.

I don't own Kamen Riders or X-Overs

Bujin Journey Through The Decade

A crimson armor warrior with blue bodysuit felt incredible pain as part of the tree beneath him exploded with two warriors breaking out in the process.

The first one was giant, green mecha like a warrior with the theme of watermelon.

The second warrior was covered in a black bodysuit with ruby-like armor and silver decoration over the body. The face of the being is covered in silver with ruby red faceplate decoration with large eyes and antennae on the forehead. The being happened to ride on what looks like a giant European dragon.

It wasn't long until the dragon turned into a giant leg with a talon.

"VERY NICE! KICK STRIKE! FABULOUS!"

The giant green robot turned into a large watermelon.

It wasn't long until the two of them descending at rapid speed with the warriors pushing them to the mad warrior who is bonded with lotus petals tried to firing petals at them. But it was too late to stop them as they struck him. The crimson armor warrior in blue bodysuit screamed in agony.

Soon the scene showed the vastness of the space and the stars. It wasn't long until something started shining across the vast space as 14 shooting stars flowing across space.

"The multiverse, also known as a maniverse, metaverse, metaverse, omniverse, or meta-universe, is a hypothetical group of multiple universes. Together, these universes comprise everything that exists: the entirety of space, time, matter, energy, information, and the physical laws and constants that describe them." An unknown voice that neither male nor female said, "The Bujin Riders are alternatives of the main Heisei-era Kamen Riders that once serves as warlords for a country of Japan that is divided into 14 territories before they passed away in their world after the demised of Bujin Gaim."

It wasn't long until the 14 shooting stars soon went their separated path from each other and venturing through parallel worlds like Earth.

"With their world being free, it's time for them to seek out successors to their power and prepared their successors without knowing it for the best or the worse."

The Holy Britannia Empire began their invasion of Japan, sparked the Second Pacific War. Missiles were dropped from the air and struck homes and buildings in Japan. The people in the buildings and their homes were not so lucky to escape as they were killed as a result. Somewhere in Japan, two children were being cornered from all angles by military soldiers and a large humanoid machine.

Damn, I know that he will send OSI to finish us off if the bombs didn't on the shelter! 10-year-old Lelouch thought in frustration. It still hard to believe that his father, the Britannia Emperor wanted them to die after casting them away into a foreign land. Especially after Nunnally loses her legs and sight!?

He thought that after separated from Suzaku that they would be in clear, but the former prince knew that was too easy and end up in this situation. His sister Nunnally was on the ground beside him.

"Big brother… I'm scared…" 7-year-old Nunnally whispered, clinging onto her older brother.

"Any last words before you and your sister send off, your highness?" The captain asked sarcastically to the frightened siblings.

"You will not send me and sister off, I will make sure that you or anyone threatened those I cared about won't get away with this!" Lelouch declared angry as he vowed to make sure that it comes true. "I will be the one who destroyed Britannia!"

This made the captain laughed before looking at his men, "Fire!"

Lelouch soon holding his sister close to him and shuts his eyes tight at this moment.

But the bullets didn't come to him or his sister as something metallic slice them down and caused gasp sounds being heard. This made Lelouch felt confused and slowly opened his eyes.

In front of the two siblings is a large armored figure with an unusual sword.

He was donned in full armor which consisted of a dark magenta, black and white combination. A black 'X' was on his chest and left shoulder. The eye optics were light green while a yellow mark on the forehead of the helmet. A silver buckle with a camera like glass in the center and surrounded by strange symbols.

"W-Who in the world… are you?" Lelouch asked startled.

"Just passing through Kamen Rider. Remember that." The magenta armored warrior spoked before stared at the soldiers. "For now, you all are my enemies."

He soon runs his hand along with his sword and charged forward at the OSI.

The men tried to fire at him, but the mysterious armor being was faster than them and sliced them down with ease.

Lelouch looks shocked at the bloodshed in front of him. Whoever helped them is very stronger than the OSI assassins.

"Big brother, who do you think he is?" Nunnally asked, nervously. Even if she doesn't know who helps them, but she still on guard.

"I don't know…" Lelouch uttered quietly while being taken by the action of the warrior.

The large robotic humanoid was soon in action as it fired missiles at the mysterious magenta warrior. But to their surprise, the mysterious armor warrior was still standing without a mess.

"If that is all you got, then I'll be finished it here with this…" The magenta warrior said, turning his sword back into a small case and draw out a card. He puts it in his buckle before closing it.

FINAL ATTACK RIDE: D-D-DECADE!

Ten holographic human-sized cards appeared in front of the mysterious warrior leading to the large robot, he then jumps in the air and then kick straight through the cards and destroyed the robot with a powerful kick.

"How did you do that…?" Lelouch asked shocked at the strangest attack he ever saw.

"It was only possible because your desire to live is the reason I was able to materialize into this world." The magenta warrior said, making Lelouch looks surprised at this fact.

"Materialized?" Lelouch asked.

"That is right. I wasn't able to do much until I find someone with a strong desire to live to show myself like now." The mysterious warrior explains.

"So that means we're connected? But it didn't tell me who are you exactly and what do you want with me?" Lelouch asked, curious.

"I'm Kamen Rider Bujin Decade." Bujin Decade answered, looking at the former prince. "Tell me… do you seek power?" he asked.

"What's the catch?" Lelouch asked.

"That you're willing to destroy the world to create anew." Bujin Decade answered.

This made Lelouch look surprised as if someone grants his wish to give him the power he needs to destroyed Britannia, but also protecting Nunnally at the same time.

"I do it…" Lelouch answered with serious resolve.

"I see." Bujin Decade said, took off his Decadriver and Ride Book before passing them to Lelouch.

When Lelouch took them, Bujin Decade soon becomes a small shimming orb.

"What the—!" Lelouch gawked at the unexpected event.

"With my Decadriver and Ride Booker passed to you, I've returned to my spirit form. I will be training you to use my power before I can pass on to the afterlife." Bujin Decade explains.

"I see." Lelouch said, "Is there anything else that I need to know about your power?" he asked.

"In the future, this world will be in great danger. The other Rider Cards in the Ride Booker, Kamen Rider cards can only be used one time." Bujin Decade warned.

"Can only be used one time?! Then what is the point of protecting ourselves!?" Lelouch asked concerned especially about the fact of great danger to this world.

"To prove that you're worthy of their power, you must travel through to other worlds to regain their power." Bujin Decade continued.

"To travel through other worlds… Do you mean parallel worlds and alternative universes? The concept is real?" Lelouch asked surprised.

"I will save the details later. For now, we should get somewhere safe." Bujin Decade said nonchalantly.

Lelouch then looks at the Decadriver and Ride Book while deep in thought about everything that Bujin Decade tells him so far. He suddenly felt a small hand holding his arm and looks at Nunnally who have a small frown upon her face.

"Big brother, are you going to travel through different worlds?" Nunnally asked quietly.

"Yeah, it looks like something bad going to happen in the future. If it bad, something tells me that Japan won't be safe." Lelouch answered as he knows that she heard the whole thing.

"Can… I come with you?" Nunnally asked hesitated.

"Don't worry, Nunnally. I will not leave you behind." Lelouch said softly. 'I hope that one of these worlds can help Nunnally see and walk again…' Though he knows that it impossible, but he still wants Nunnally to be able to see and walk again.

He soon placed the Decadriver and Ride Book away as he carried Nunnally on his back before started walking again.

(6 years later)

A raven hair young man just made a move that left his opponent in shock.

"Checkmate," Lelouch said, holding back a yawn. "I can expect to see the money transferred into my account within the hour?"

"Ye-Yes. Of course," the old man stammered over his words as he motioned towards his secretary. "The money should be there in a few minutes." The secretary nodded as she was fiddled with a tablet. Once she was done, she got out of the tablet and showed it to Lelouch.

Lelouch's phone dinged and lit up.

"Perfect." Lelouch stood up and began walking away. "Thank you for the game and apologies for rushing out so quickly. If I don't make it back to school soon, I'll never hear the end of it."

Following him to the door was a blue-haired boy.

"Did you see the look on his face?" Lelouch's blue hair companion, Rivalz snickered. "It's been a while since we've met some noble with that much self-confidence."

"Careful, Rivalz. They can still hear you," Lelouch scolded as they left the mansion.

"So? Even a Britannian noble won't do something stupid to another Britannian's kid," Rivalz said as he starts up his motorcycle. Lelouch hopped into the sidecar before the two teens placed on their helmet as Rivalz practically blazed out of there.

"I take it that Shirley kept calling you?" Rivalz asked loudly against the wind.

"You have no idea…" Lelouch sighed and then grumbled, "It sounds like someone trolling us." He cast his eyes to the side and watched the scenery flew by.

"Is there something on your mind?" Rivalz inquired.

"Just tired…" Lelouch muttered.

Suddenly Lelouch hears a strange ring sound in his head as he looks around. But unknown to him, the mirrors nearby were shimmering.

"Lelouch, is there something wrong?" Rivalz asked, confused.

"Did you hear that strange sound just now?" Lelouch asked, tried to pinpoint the source.

"What?! All I can hear is the wind!" Rivalz exclaimed while driving.

Lelouch still has doubtful expression before the two male teens saw a large building was dissolved right in front of them while people are running away in panic.

"Buddy, can you tell me that I'm not dreaming right now… or did that just happen?" Rivalz asked, looking scared and disbelief at the same time.

"No… that building just dissolved…" Lelouch responds with a similar expression.

That wasn't just the only thing they saw on that day as they saw something resembled grey distortion mirror in the sky as large flying monsters making way into the city.

"No way!" Rivalz exclaimed in shock, "What in the world is going on!?"

"This… is like the end of the world," Lelouch uttered in disbelief. 'I-I never imagine the great danger would be like this…' he thought to himself in shock.

"Whoa!" Rivalz shout as he moved the motorcycle out of the way from the jaw of a flying monster that resembled a Quetzalcoatlus. "That is a huge bird!"

"Rivalz, we need to head back to school now!" Lelouch snapped his friend out of his state of shock.

"On it!" Rivalz shouts without any hesitation, hitting the accelerator at the maximum again.

I hope that we aren't too late… Lelouch thought seriously.

To their horror, their school has been targeted by the monsters as well. Many Ashford students running for their life from strange monsters.

"There are more of them here!?" Rivalz exclaimed in shock. He wasn't sure what to do especially when there aren't any Britannian officers around to stop these monsters.

Lelouch looks around the academy before noticed his childhood friend Milly Ashford was pushing his sister by her wheelchair not far from where they are. He immediately got out of Rivalz's motorcycle and runs after them immediately.

"Nunnally!" Lelouch shouts as he not letting his sister out of his sight.

"Wait up!" Rivalz soon chased after his friend from behind.

As they are running through the hallway, they can't help but being look horrified at the sight of what has the monsters done to the school.

The two boys soon find Nunnally with other female members of the Student Council being cornered in one place. Sayoko is holding her left arm which is bleeding from possibility struggle against the monsters that were swarming around them.

"Nunnally! Shirley! Nina! Prez!" Rivalz shouts before he and Lelouch were soon blocked by a distorted glass-like wall in front of them.

"Nunnally!" Lelouch shouted as he was banging on the distorted glass-like wall. But his fist couldn't do anything to the large wall in front of them.

"Big brother!" Nunnally cried out when hearing her older brother's voice.

He and Rivalz tried to break through the glass wall, but no matter what they do, it won't break down and the monsters were getting close to the girls.

"It's no use, Lelouch! Whatever this thing is made of… won't let us get through!" Rivalz said with a frustrated expression.

Lelouch gritting his teeth and reaching for his bag to get out something. He didn't want to do this in front of everyone. But with his sister and everyone is in danger, there is a little option left for him in secrecy.

Lelouch soon got out his Decadriver and placed on his waist, made a silver belt appeared and wrapped around his waist. He then pulled the side handle of the Driver to opened before taking out Decade Card from the Ride Book.

"Henshin…!" Lelouch shouts seriously.

KAMEN RIDE: DECADE!

Then several Rider Symbols appeared and turned into armor silhouettes. They merged with him and now donned in white and black armor with a black 'X' symbol across his chest and the helmet has green bug optics. Nine red plates emerged from the Decadriver and went to his helmet, with the middle plate having a yellow gem on the forehead. His armor becomes magenta on the sides, black in the middle, and white on the inside of the arms and legs.

He had become Kamen Rider Bujin Decade.

Bujin Decade then punches the distorted wall and it shattered like glass, catching everyone's attention on him in the process.

"No way…" Rivalz gawked in surprise.

"Lulu…" Shirley whispered in disbelief.

"T-That is impossible…" Nina gasped in shock.

"Milly, get Nunnally and everyone to safety now! I'll handle them!" Bujin Decade said to his childhood friend before the monsters coming toward his direction.

Bujin Decade got out his Ride Book and it changed into sword mode. He soon charged forward while delivering several slashes the enemies in his path.

Rivalz still can't get his mind over what he witnesses in front of him. His friend had become a pink armored warrior! But what he can't wrap around his mind is why he is wearing pink!

"Rivalz, we need to get out of here while Lelouch takes care of those things!" Milly said, taking his hand and dragging him away from the battle.

"But, what about—" Rivalz didn't get to finish his sentence as another explosion covering the entire field where their friend was.

"He will be fine! Now come on! We need to head for the Club House!" Milly instructed everyone to move on in a hurry.

Meanwhile, Decade turned his sword into a gun mode and firing at the monsters to get their attention on him.

"It looks like I might have to use them sooner than I expected…" Bujin Decade said, getting out a card from his Ride Book.

He soon inserted the card into his Decadriver.

KAMEN RIDE…

Bujin Decade closed the buckle.

W!

Soon Bujin Decade was surrounded by a small twister of wind with strange pixels attaching to his body. The pixels soon formed armor and his body soon became of Bujin W.

Bujin D-W suddenly flicking his wrist and pointing at the monsters silently, before Bujin D-W started to move again. He soon sends several kicks with hurricane power and punches to throwing the monsters back from him in the process.

Bujin D-W got out another card from his Ride Book.

"This power… it truly something," Bujin D-W remarked before inserts into his Decadriver.

FORM RIDE: W LUNA-TRIGGER!

Soon Bujin D-W's form change as he becomes Bujin W LunaTrigger Form. He then inserts another card into his Decadriver immediately.

FINAL ATTACK RIDE: W-W-W!

Soon Bujin D-W got out a blue gun known as Trigger Magnum and pointed in front of him before pressing the trigger.

"Eat this!" Bujin D-W fired the shot which turned into multiple energy shots and hits the monsters that were a presence. The attack struck the monsters and they exploded in the process.

Bujin D-W looks at himself from the mirror before his Bujin W armor vanished and returns to his default form, "So that is how long these cards would last…" he commented.

Bujin Decade decided on returned to Nunnally and others. He knows that there will be some explaining he needs to do before the journey begins.

He turns around and ends up being swallowed by a distort gray wall before ending up in what looks like a beach. Bujin Decade looks around with a shocked expression behind his helmet.

"How the hell did I end up here!?" Bujin Decade exclaimed in shock.

But he wasn't alone as the sand started to gather around and changing into more monsters in the process.

"I don't know who dragged me here… but I will get back to others!" Bujin Decade stated with a serious tone before quickly drew out another card.

He soon inserts into his Decadriver.

KAMEN RIDE: DEN-O!

Soon silver rectangles surrounded Bujin Decade before he donned the armor of Bujin Den-O. He then turned his Ride Book into a sword then slashes the monsters that coming from the sand. Two monsters were coming from both his left and right, but the Rider wait before moving out his way as they smack right into each other.

Bujin D-Den-O soon drew out another card before insert to his Driver.

FINAL ATTACK RIDE: D-D-DEN-O!

Red energy came from the Decadriver and went towards the sword. The blade flew out of it and floated in the air.

Bujin D-Den-O then swung the bladeless sword towards the monsters. The floating red blade followed its arc and put a large cut across the monsters and caused them to explode. However, he wasn't allowed to go as another distort mirror emerged with monsters that were mainly white and look dangerous to him.

The armor of Bujin Den-O vanished after the card released from his Decadriver and Bujin Decade pulled out another one immediately.

"Damn, how more of them are there?" Bujin Decade questioned before placing the card into his Decadriver.

ATTACK RIDE: BLAST!

He then drew out his Ride Book and changed it into a gun before firing at them. But the one who didn't bother was a grayish creature that resembled an elephant and tackled him back.

"It looks like I might need another one," Bujin Decade groans while getting himself up from the ground and pick another card from the Ride Book. He quickly inserts into his Decadriver.

KAMEN RIDE: FAIZ!

Soon red neon lines coming from his Driver and surrounded him until they engulf him in a huge light. When they faded, Bujin Decade has become Bujin Faiz. He then took out another card from his Ride Book and insert it into his Decadriver.

ATTACK RIDE: AUTO VAJIN!

It wasn't long until the grayish creature and other monsters were hit by bullets from a large robot known as Auto Vajin. Bujin D-Faiz comes to his side and took out something from Auto Vajin's shoulder which is the sword known as Faiz Edge.

"Keep firing at any hostile enemies that come in my direction, Auto Vajin." Bujin D-Faiz said before charging forward.

Bujin D-Faiz then starts slashing the enemies in his presence while Auto Vajin giving fire support from the distance. He slashes them without any mercy before they all crumble into dust and blue flames in the process.

"That should be the last of them…" Bujin D-Faiz said before his armor returned to normal form.

But it wasn't long until he noticed everything around him frozen in time.

"Oh great, what now…" Bujin Decade groan.

"It's best that you get back to your home." A female voice said while Bujin Decade looks around for the voice, "You can't find me as I'm speaking in your head, Bujin Decade."

"Who are you?" Bujin Decade questioned.

"You can call me the Caretaker. With the danger appearing here, time in this world is slow down while you must embark on your journey through other worlds until you return." The Caretaker said.

"What's in it for you?" Bujin Decade questioned, knowing that Caretaker want something in return.

"This world can't be changed unless destruction brought forth before creation." The female voice said.

Bujin Decade didn't say anything and glanced where Auto Vajin was… a magenta, black, and white Honda DN-01 motorcycle. This was known as Machine Decader.

"If this world's time been slow down, then there is nothing much too worried besides the journey." Bujin Decade noted before getting onto his motorcycle and drove back to Ashford Academy.

AN: That's the end of the one-shot here. The Riders here that will be focused are the successors of those who were picked by the deceased Bujin Kamen Riders. I won't go into details about others, but this one is a year before Code Geass canon begin.
