Hi Everyone. Unfortunately my brother won't be able to write stories for a long while due to college work so he gave me his account and I've decided to write my own story since I can't really write like him. This is a crossover between Kamen Rider and RWBY…. But not the usual kind. Anyway hope you enjoy the story

Chapter 1: The new legacy

It was a beautiful morning within the kingdom of Vale. The streets were bustling and birds were singing. Within this town was a book store named "Tukson's Book trade". Underneath the sign read "Home to every book under the sun!" Inside this book store was what appeared to be a near middle aged man with thick black sideburns wearing an apron with the store's logo on it with a name tag reading "Tukson" who was looking over his stores inventory before hearing a crashing sound, causing him to sigh. He entered another room of the store to see a young man around in his early 20's lying on the floor and rubbing his head. The young man had dark blue hair that covered his eyes yet somehow retained its spikiness along with bright green eyes. He wore a magenta shirt and black jeans while also wearing an apron with the store logo on it as well. He had a name tag that read "Azure"

"Ow. The damn ladder collapsed" Azure complained as he stood up, causing Tukson to raise an eyebrow "That's odd. It was fine this morning when I cleaned the shelves in the other room" Azure began to pick up the pieces of the broken ladder "I'll put these in the bin outside" Tukson nodded as Azure walked out leaving Tukson to ponder "I'll get him to buy a new ladder later" He then left the room to go back to the register.

Lunchtime

Azure was walking through town having bought himself some sandwiches for his lunch break while waving at an old man who was sweeping in front of a place called "From Dust till Dawn" as he passed the place he accidently bumped into a little girl with dark red hair, causing her to fall down "Whoa, sorry about that" he helped the girl up who smiled at him a bit shyly "I-It's okay mister. T-Thank you for helping me up" She nodded and ran towards a little boy with the same hair colour before the two kids ran off to play. Azure smiled at the scene before walking back to Tukson's.

When he got inside he reached into his wallet and pulled out a photo. In the photo was what looked like a younger Azure smiling with a girl around the same age as him back then who was smiling a little nervously. The girl had brown hair that went to her shoulders with a few white streaks in it and her eyes were heterochromic with one eye being brown while the other was pink and wore a white sundress with pink shoes. Next to them was a boy around the same age with black hair that was combed down and blue eyes. He wore a blue shirt with a black hoodie and blue shorts. He was trying to give off a kind of "cool" impression with crossing his arms with a smirk but Azure just found it funny. Behind all 3 of them was an old woman with white hair tied into a bun while wearing a brown dress. Azure gave a small smile at the picture before putting it away and finishing his sandwiches before getting back to work.

Later

Azure was unloading new books with a groan "seriously. I know our slogan is "Every book under the sun" but this is ridiculous." Tukson, who was unloading another box of books, laughed "Well got to make sure we don't get called liars" Azure laughed as well. Tukson finished unloading the books and stood up before looking at him "After you're done can you go get a new ladder for tomorrow?" Azure nodded and quickly finished unloading the books.

As Azure walked down the street to buy a new ladder he saw a woman with the same hair colour as the children from earlier frantically searching the streets before running to him "Excuse me! Have you seen my children?! They have dark red hair like mine!" Azure raised an eyebrow before answering "I saw two children with that hair colour a couple of hours ago, why?" The woman began panicking "I can't find them! I've been looking for nearly an hour!" The woman looked ready to break down crying until Azure placed a hand on her shoulder "Don't worry. I'll help you find them! Where have you looked?" The woman took deep breathes to calm herself and explained where she had looked for her children.

Azure was running around town in order to find the two kids "Dammit. Where the hell could they be?!" He continued searching until he heard a shriek from the forest outside the town and quickly ran towards the source of the shriek. When he found the two kids his eyes widened, the kids were holding each other pressed against a tree as they were surrounded by 3 Grimm.

It was hard to describe what the Grimm actually are. They are described as "creatures of destruction" by a lot of people. They are also said to be drawn to feelings of negativity- such as envy, sadness, loneliness, and hatred- often congregating towards the source of these emotions. Azure remembers reading at one point that ancient cultures believed that Grimm were animals possessed by evil spirits or were the spirits of once tortured animals. These Grimm appeared like pitch-black, featureless shadows in the shape of wolves, with red eyes and jaws. This lead Azure to believe that these Grimm were "Beowolf". Acting quickly he picked a nearby rock and tossed it at one of the Beowolf, drawing their attention towards him "COME AND GET ME YOU STUPID OVERGROWN MUTTS!" He sent the kids a look reading "Run" before running deeper into the forest to make the Beowolfs chase him. Once he and the Beowolfs left the kids ran off to their mother.

Azure get running as the Beowolfs chased him. He could feel his lungs inflate and he could hear his heart in his throat as well as his legs beginning to burn. He didn't turn behind but he could tell that the Beowolfs were catching up to him but he refused to give up. There was no guarantee that the children had made it out of the forest yet so the longer he could stall the Beowolf the better chances the kids had of escaping. As he running he heard a voice "Dive to the right" Azure decided to listen and dove to the right, jumping into a hole in the ground.

Azure slid down the hole for a couple of minutes before landing in what appeared to be a underground chamber. He stood up and dusted himself off before looking at the chamber around him. It looked like a stereotypical chamber you'd often see in movies. Dirt, cobwebs, torches and a shrine in the middle. In the shrine was what appeared to be a relic that was shaped like a rectangle and was completely crusted over. "What is this?" Azure pondered until he heard the voice again "Grab the driver!" Azure jolted in shock "Huh? Driver? You mean this?" He asked as he touched the relic as the whole room was bathed in a bright light, Causing Azure to cover his eyes.

When he opened them he was standing in the middle of a white void "W-Where am i?" He pondered as his voice echoed around the void. He continued looking around until he heard footsteps behind him. He quickly turned around and saw a new figure. It was man that appeared to be in his 30's with matted down brown hair. He wore a magenta shirt like him toppled with a black jacket and trousers. Also around his neck was what appeared to be a pink camera "Somebody finally found this place" The man said as Azure raised an eyebrow "so where exactly is here?" Azure asked the man who simply smiled "This is a temple. Simply put this where a Kamen Riders power is stored until someone worthy finds it" Azure just looked confused "What exactly is a "Kamen Rider" and who are you?"

The man looked a little shocked that Azure didn't know what a rider was but decided to answer his questions "A Kamen Rider is a hero that's willing to sacrifice everything they have to save others, whether it be their ideals, their very humanity or even their own life. It's a title that is earned for those who has made that sacrifice and still came out better for it. A Kamen Rider is a symbol that no matter what, the people will always be protected." The man said this with complete seriousness in his eyes, leaving Azure in awe. These "Riders" the man spoke of sounded like Hunters and Huntresses to him. The man then spoke up again "As for who I am…. My name is Tsukasa Kadoya. Kamen Rider Decade. Or at least I was" This made Azure look at him questioningly making the now named Tsukasa speak up "Like I said this temple is where a riders power is stored when they become too old or they die. When I became unable to fight anymore I stored my power within this temple."

Azure decided to ask another important question "So why am I here?" Tsukasa looked at him with a smile "It's because of your selfless act. How you basically sacrificed your own life to save those innocent bystanders. Even though you're powerless you still thought of others instead of yourself. Like a true Kamen Rider. I want you to take my place as Decade" Azure's eyes widened "M-Me. N-No way. I'm not strong or fast. I only helped those kids because it was the right thing to do!" Tsukasa smile got bigger "and that's exactly why. You didn't do it for a reward or to become popular, you did it for the right reason. I'm not forcing you to take this power, the choice is entirely up to you. Kamen Riders exist to protect people. Will you take this power?"

Azure thought about this offer. On one hand, he was not a fighter who felt worthy of such power….. on the other hand, With this power he could many people. His mind immediately flashed to a memory of when he was 7. The young him was holding up a toy sword while the girl from his photo was sitting on a rock smiling "I want to be a hero! One that beats up the bad guys and saves the day! Do you think I could do it?" The girl nodded as her smile widens.

Azure looked at Tsukasa "I'll do it. I'll become the next Decade" Tsukasa smiled "Very well. I grant you the powers of Decade!" The white void started flashing, making Azure covers his eyes.

At Beacon

A white haired middle aged man was taking a sip of his coffee until he felt a power surge "So Tsukasa finally found someone to take on his power….. interesting" He looked at a drawer that was flashing and opened it up revealing a small black rectangular object with the letter "S" on it

In a faraway Kingdom

A young man with long brown hair was sitting by a campfire and suddenly looked to the sky "So a new Decade has been born…." The man then looked down to a card in his hand with the word "CHANGE" written on it.

Back with Azure

Azure opened his eyes and saw he was back in the forest he quickly looked around and saw that the hole that lead him to the chamber was gone "Was it all a dream?" he then noticed the relic he picked up in his hand only know it wasn't crusted over. It was now coloured white with a large glass arc in its center with a small green orb on the top of the circle. On its sides was two metal plates with three small circles on each plate and on the top of it the words "DECADE" were written. There was also nine symbols surrounding the arc with nine other symbols around the first circle of symbols (Neo-Heisei symbols except Zi-O). Attached to his waist was a black book that looked to be filled with cards when he opened it

"Wow. So it wasn't a dream" He started marvelling over the new device until he heard growling. He turned around and saw the Beowolfs from before slowly crawling towards him ready to lunge "Crap. What do I do?" He immediately rolled out of the way from one of the Beowolfs and heard Tsukasa's voice "Attach the driver to your waist quickly and open it up" Azure quickly did so "now take the decade card out and yell "Transform!" before inserting the card into the driver" Azure pulled out the Decade card from the black book before turning it around "Transform!" He then inserted the card into the driver making it light up

KAMEN RIDE:

Azure then closed the driver making it cry out again

DECADE!

Nine spectral shadows formed a line on both of Azure's sides, each with a symbol on its middle. The shadows soon merged to Azure one by one as he was enveloped with materializing armor parts followed by mechanical screechings starting from its waist forming from the torso to the thighs, legs, arms, shoulder pads and finally forming the helmet.

The full-body armor had an 'X' shaped black line with white outlines along from its right shoulder pad to its chestpiece. It was a bit bulky but still looked that it matched Azure's body posture. Its color was plain black and grey at first along with white on its inner arms and legs, except for its green visors.

Several black 'cards' appeared from the driver, flying towards the Beowolves' positions and flailed rapidly, harming any that tried to get near him. After fending them off a bit, the 'cards' soon flew towards Azure's head. He surprised and flinched a bit at this but he barely got the time to blink. It turned out that the 'cards' only attached to form the helmet's horns like the picture in his card without hitting his own head.

Azure stared at his hands "Amazing. I really transformed" He gasped in amazement as different instructions started flashing in his head, how to use the cards and how to fight using them. After the instructions faded he turned his attention back to the Beowolfs "Time for some payback" He cracked his knuckles as the first Beowolf charged him. As it did he readied his fist and flung it at his target's gut, delivering his first strike, and his 'first blood'. The Beowolf flew back meters far as it broke several trees before finally stopping at a tree, cracking its trunk for a bit.

"Whoa, never thought I'd become this strong." Decade said

Thinking that it wasn't enough, he decided to charge his fists with more power by clenching them tightly, feeling another power surge flowing to them. As two other Beowolves proceeded to attack, he delivered several hard punches to one of them before doing an uppercut to its chin, sending it mid-air with him jumping a few feet higher than the creature to deliver a harder blow on it. He used his right foot to send it back to the ground in higher velocity, caving the Beowolf's torso before it turned into dust, as it did the other two Beowolf began howling, causing even more Beowolfs to come out growling at him.

The other Beowolf went to attack him from behind. Decade quickly responded by grabbing and throwing the Grimm to a nearby tree. He dashed to it as soon as it landed on the tree, reinforced by its armor's spring attachments on its joints, making him dashed faster than a normal human. He delivered a single right hand punch to its head at a breakneck speed, shattering its head along with caving the trunk behind it.

He was also saw that the Beowolf he first attacked came back to him. He pulled his stucked right arm quickly to elbow the Grimm's skull before turning at it to slam it down by grabbing its head, spinning for the ground slam and finally ripped its head off forcefully. It also turned into a dust alongside its dead body.

Now what's left is that he still got four who were 'clawing' at him. As they surrounded him, Decade went to check on his Ride Booker, preparing its next function. He detached the device from his waist and pulled the black handle a bit, revealing its new function as a gun, followed by the HUD displaying target marks on the Beowolfs. He fired several laser blasts at them before proceeding at the two of them, delivering several punches and kicks followed by gun blasts either in long range or at a point blank range for reinforced close encounters.

After he managed to corner them, he pulled out a card from the device with a picture of him in the armor shooting laser rounds along with four spectral projections of his weapon. He opened his driver to insert the card.

ATTACK RIDE : BLAST!

Decade charged his weapon with the laser's energy and aimed at the two Beowolves, firing more powerful rounds to them followed by not only four, but dozens of moving pink spectral guns, all aimed on the same targets. He kept firing at them before finally exploding into black dusts.

He then pulled the handle following the direction of its black line and it unfolded a carbon and a silver sharp blade, turning the weapon to its sword mode. He went to the other Beowolf on his left and slashed it for a few times. Sparks flew from the bruised creature as he pulled another card, with a picture of him holding his sword while its edge glowing in magenta, along with some after-images of his sword. He inserted it to his driver.

ATTACK RIDE : SLASH!

As his sword's sharp edge glowed in magenta, Decade slashed the creature in 'X' shape as it exploded. He then looked at the last Beowolf who charged at him but he was able to dodge by jumping over it. The Beowolf stopped charging as Decade pulled out a yellow card with his logo on it "Let's finish this with a bang" He then inserted the card into the driver

FINAL ATTACK RIDE: D-D-D-DECADE

Large holographic versions appeared in front of him as he jumped up and stuck his leg out. He then glided through the cards and started glowing before his leg went right through the Beowolf and it exploded. Azure gave a sigh of relief as an image of Tsukasa appeared in front of him. "Not bad. Though I would've done it much cooler and I look better in that armor" He said with a joking grin, making Azure smile as his armor dispersed "Thanks for everything Tsukasa" He said as Tsukasa nodded before disappearing. Azure began to walk back into town until he saw a white haired middle aged man holding a cane in front of him "It's an honour to meet you…. New Decade" As the man said this the screen zoomed out revealing the Decadriver before closing

Next time on Remnant Rider:

Azure: My first memory is being stranded in front of a doorstep

Ozpin: The birth of Decade symbolizes the coming of a new age

Yang: Ooh. My babysister is coming to Beacon with me

Weiss: WHAT ARE YOU DOING?!
