"There's something I wish to tell you about, Sunset. Something I think will be of vital importance to you in the future." These words came from a tall light gray alicorn with a flowing mane and matching tail in light cerulean, light turquoise, very light cobalt blue, and pale heliotrope colors, light magenta eyes, and a glowing sun Cutie Mark smiled down at her young student.

An amber colored unicorn with a bacon colored mane and tail, cyan eyes, and a yin-yang styled sun for a Cutie Mark looked up at her mentor in interest, pondering, "What is it, Princess Celestia?"

The Princess walked over to a door and with a golden aura of magic, she stuck her horn inside a small hole and unlocked the door as it slowly opened to reveal an antique looking box that she levitated to the unicorn, aptly named Sunset Shimmer.

Sunset curiously took the box in her own cyan aura and opened it in confusion, revealing a red colored book with an illustrated dragon on the front, entitled Brave Dragon on the front.

The young unicorn's eyes widened in amazement as she looked at Celestia and asked, "What is this?"

"It is an artifact of utmost importance that I received a long time ago from a young unicorn not unlike yourself," Celestia serenely smiled at her as she spoke, "He requested that I keep this book sealed and only activate it when it's truly needed. But he also told me that the Sword of Flames shall reveal itself to the new bearer of the Brave Dragon when dire times are upon the holder of this book." She rested a hoof on Sunset's shoulder, her expression now serious as she requested, "Sunset Shimmer, I need you to keep this artifact safe and only use it when it awakens to fight off any new threats that arise."

Sunset levitated the Wonder Ride Book into her hoof and looked at it, almost hearing a dragon like roar in her mind, before she looked up at her mentor with a proud expression and responded, "I will, Princess. I'll guard it with my life."

"I will... Princess..." Muttering slightly in her sleep, Sunset Shimmer woke up in her bed from reliving her memory as a dream and blinked slightly as she remembered where she was with a sigh as she groaned, "Oh, right." Frowning a bit, she opened her bedside table drawer and pulled the Wonder Ride Book out, looking at it with a curious expression as always as she couldn't help but mutter to herself as she had many times before, "Why would Celestia give me something important? And... what is this thing anyway?"

Suddenly, she heard her alarm go off and turned it off, sighing as she muttered, "Eh, I'm sure I'll figure it out later. Better get ready for school anyway." She frowned as she remembered everything she had done to Canterlot High in her spite: Trying to discredit a new Princess of Equestria who was getting used to the human world, tearing apart friendships and ruining other people's lives before then, almost killing Princess Twilight and the Human Mane 5. Everyone was still cautious of her since then, and she didn't blame them. Heck, she only blamed herself for the issue. But there was no way she could know that she was gonna be able to change everyone's views on her in a significant way, specifically through Brave Dragon itself.

End Theme

Meanwhile, in an undisclosed location, three mysterious figures were meeting to discuss some plans as the first asked his comrades, "Is everything prepared?"

"Indeed it is, Legeiel. Our first victim has already received their Alter Ride Book." A second figure reported to him.

"Excellent, then we can continue what we started several years ago," The first voice spoke again.

"And when we gather the remnants of the Almighty Book, we can rewrite the world into our own image," a third voice joined in, seeming to relish the idea.

Soon at Canterlot High, Sunset pulled up on her bike, which was a Honda CRF45OL designed to look like a dragon. This ride was called DiagoSpeedy, and it would be useful for Sunset's future endeavours.

She got off her bike, returning it to its Ride Book form as it spoke "Engine Kyuukan!" and headed into the school, holding her Wonder Ride Book in her hand tightly as she dodged the students who glared at her and whispered some mean things about her behind her back, sighing sadly as she remembered her past once again.

Arriving at the band room, she came face to face with her friends and waved shyly, "Uh, hey guys."

"SUNSET!!!" A light pink skinned girl with fluffy darker pink hair and light blue eyes tackled the bacon-haired girl in a tight hug as a squeaky toy sound emitted while she grinned.

Sunset chuckled and smiled as she looked at the girl with one eye open. "Nice to see you too, Pinkie," she spoke as she got the girl off her.

"Honestly, Pinkie Pie! You really need to find a better outlet for all of that energy!" A white skinned girl with curly purple hair and sapphire blue eyes scolded the pink party girl.

"Ah, let her get her hugs in, Rares." A light orange skinned cowgirl with blonde hair and green eyes spoke as she smiled at her fashionista friend, "You know Pinkie ain't happy until she's got her morning routine done."

"Well, let's just hope our routines go back to semi-normalcy after this," A light pink haired, light yellowed skinned girl with aquamarine eyes said quietly as she hugged a bunny in her arms, "We don't really need another crazy event happening so quickly afterwards." Her eyes suddenly dilated as she realized what she was talking about and she looked at Sunset quickly and told her, "Uh, no offense."

"None taken," Sunset sighed softly, looking away sadly.

"Still upset about how rough you were, huh?" A rainbow haired girl with light cerulean skin and raspberry red eyes asked out of concern.

Sunset sighed and responded, "You have no idea. I just keep wishing I can change it somehow, make amends for what I did in the past and all."

Pinkie smiled as she spoke quickly while moving animatically to illustrate her crazy idea, "Ooh, maybe you'll become a superhero with the power of stories from a world beyond our wildest imaginations and save all three worlds - the unknown world, our world, and Equestria - from being recreated by a trio of crazy monsters and their creations who use darker versions of those stories!"

The rest of them looked at Pinkie in absolute confusion; in all their lives, they had never heard anything so... so out there.

"Pinkie," Applejack finally spoke up, "in all the years I've known ya, I've heard you say some crazy things before, but that absolutely takes the cake."

"What? It's not my fault the author knows what she's doing when assigning Sunset her new destiny," Pinkie responded with another squeak as she grinned.

Sunset shook her head as she turned away and ran into a boy with electric blue hair, matching blue eyes, and light orange-yellow skin, hitting the ground as her Ride Books fell from her bag.

"Whoops! Sorry about that, Sunset," Flash Sentry smiled and helped gather her stuff, taking notice of the Brave Dragon Ride Book with his eyes widening as he spoke, "I've seen this before... in one of my dreams..."

Sunset looked at him in surprise, gasping a bit before she asked, "What were your dreams about?"

He looked at her and the others, noting their interest in his story, before he nodded slightly and got up, handing Sunset her Ride Books and ushering them all inside before he closed the door behind himself, turning and sighing softly as he spoke, "What I'm about to tell you guys is super confidential, only told to others who have Ride Books like Sunset. Pinkie Promise that none of you will tell anyone not privy to this information."

The girls all spoke in unison as they recited the Pinkie Promise: "Cross my heart and hope to fly, stick a cupcake in my eye."

Flash nodded, satisfied with the unified promise before he pulled out a Ride Book of his own, this one being a light turquoise in color and bearing gold decals, the cover having the image of a man holding two swords and the title being Kin no Buki, Gin no Buki.

Sunset's jaw nearly dropped as she saw the book, looking at Flash in shock as she stuttered, "H... wh... how did you...?"

"That's where things get interesting, actually," Flash smiled a bit before explaining his tale.

("Last night, I woke up in this vast land that was surrounded by greenery and had bubbles floating around that didn't pop, like it was a fantasy world or something,") Flash explained.

He opened his eyes to see a green landscape with several buildings and a monolith far away, getting up and looking around in amazement before he saw a bubble floating by him and poked it curiously, surprised to see it not pop and instead float away. "This is unreal."

("Suddenly, I heard this voice speaking to me from behind.")

"It's an amazing place though, isn't it?" A voice casually asked him.

Flash nearly jumped out of his skin as he whipped around to see a young man about his age standing there with a smile on his light tan face, brown eyes holding a knowledgeable expression behind his black hair, his pose relaxed underneath a casual business suit.

Flash blinked in confusion before he asked, "Who are you?"

The man stepped forward and answered, "I'm Touma Kamiyama, the newly designated guardian of Wonder World. I need your help."

("I had no idea what he needed from me, but I wasn't gonna pass up an opportunity to help.") Flash nodded as he spoke determinedly, "What do you need me to do?"

Touma handed Flash the Kin no Buki, Gin no Buki Ride Book. "Some old enemies of mine have resurfaced and have captured one of my dearest friends. The Ten Swordsman are needed to save Earth and Wonder World once again."

("I was willing to fight for everyone here, so it was a no-brainer on my end.") Flash nodded and accepted the Ride Book, looking at Touma as he asked, "How will I know who is chosen by you?" ("I wasn't prepared for what he told me next though.")

Touma smiled once again and responded, "The Book and Seiken will appear to their chosen wielders, but Saber has already been chosen. A certain ex-girlfriend of yours received her Ride Book a long time ago in her home world when I entrusted it to her then mentor."

("I was so startled that that was when I woke up.") Flash jumped up to a sitting position and looked at his hand, seeing the Ride Book. "That wasn't a dream."

"So when I saw that I had also gained the Seiken Saikou Driver, I went looking for you guys immediately after getting to school," Flash finished his story.

Fluttershy blinked slightly as she spoke quietly, "Sounds like an awful lot of pressure, but... I think I know what you're talking about as well. I watch a few Neighponese Toku shows, and that Driver sounds familiar..." She frowned in thought.

Suddenly, a loud CRASH got their attention as Applejack was the first to ask, "What in the hay was that?!"

Flash frowned as he responded, "Sounds like what Touma was telling me about, old enemies resurfacing. Let's go!" He dashed out to the school courtyard.

The HuMane Six looked at each other and nodded before they followed Flash out to the courtyard, all of the girls gasping in fright as they saw a rock like monster terrorizing the students.

Flash stepped forward and placed an odd buckle on his waist, straps appearing magically and locking the buckle in place as the girls heard a disembodied voice: "Seiken Saikou Driver!" "Time for the dual metal sword to illuminate the world!" He opened his Ride Book as it spoke with the same disembodied voice: "Kin no Buki, Gin no Buki! Gold or silver?" He opened the buckle up to allow it become a sword before slotting the Ride Book in and pulling the sword out, striking a pose. "Saikou Hakkou!" "Henshin!" He swung his sword to the side as he turned into light, being absorbed into the Seiken, much to the girls' shock, while another announcement rang out: "Who is the shining sword? Saikou Issho: Kingin no chikara wo eta kagayaku ken! Saikou!"

The girls felt their jaws drop, although Pinkie's jaw literally hit the floor somehow as Flash, now the Seiken known as Saikou, floated in midair.

"Whoa, didn't expect this, but I'll roll with it," Flash seemed as surprised as the girls before he flew forward and started slashing the Golem Megid, seeming to easily be holding it back alone.

Sunset frowned as she watched him fight, nervously clenching her fists as she remembered her lessons on the stories of the world, specifically when she had expressed interest in writing as a younger filly.

"Anything is possible if you just believe in yourself," Celestia had urged her long ago.

'That's right, Celestia believed I can do anything, but I always used that belief for power. Now I have a chance to rewrite my story!' Sunset looked up with a determined expression and ran forward courageously, grabbing the Kougouken Saikou and slashing the Megid with it while taking some punches due to her lack of sword-fighting experience.

"Sunset, what are you doing?! Are you crazy?!" Flash would have been lying if he thought he wasn't worried for his ex-girlfriend.

Sunset grunted as she was knocked back, hitting the ground and coughing up some blood before she got up. "Maybe, but I know if I don't do something to help, everyone's gonna get hurt or worse! I'm not letting that happen again, or anytime ever! If this is my destiny now, then I will fight to protect the stories and lives of everyone!"

As if responding to her spark of courage, the Brave Dragon Wonder Ride Book lit up in a red flame and opened a portal that dropped out a stone sword as a dragon's roar was heard from inside the portal.

"Sunset, you know what to do!" Flash shouted to her quickly upon seeing the sword.

Sunset nodded, "Right!" She ran forward, sliding under the Golem Megid as it tried to swing at her, and grabbed the sword from the ground where it had landed, getting back to her feet quickly and letting Flash float beside her as she pulled out her Wonder Ride Book.

In response, the Brave Dragon Ride Book transferred its red flame to her sword, transforming it into a device with three slots and a red handled sword inserted inside it as she heard a similar voice to the Saikou Driver: "Seiken SworDriver!"

She looked at the Driver in amazement before she placed it on her waist, the Driver locking in as she clenched her fists. "Let's rewrite the future!" She held up her Ride Book and opened it. "Brave Dragon! Katsute subete wo horobosu hodo no idaina chikara wo tenishita shinjuu ga ita..."

The remaining HuMane Five looked on, Fluttershy grinning widely as she gasped in excitement.

"I will... protect this school!" Sunset closed the Ride Book and loaded it into the first slot, grabbing the handle of the sword as a larger version of Brave Dragon appeared behind her before she drew the sword out, opening the massive book behind herself. "Rekka Battou!" She swung the sword so it ran horizontally across her body. "Henshin!" She created a flaming cross slash that flew forward as the dragon from the book circled around her and formed her suit, the flames merging to become her visor afterwards. "Brave Dragon~! Rekka Issatsu! Yuuki no ryuu to Kaenken Rekka ga majiwaru toki, shinku no tsurugi ga aku wo tsuranuku!"

Insert theme - ALMIGHTY

The girls were shocked, but Fluttershy was jumping for joy as she screamed loudly, "KAMEN RIDER!!! SUNSET'S A KAMEN RIDER!!! SHE DID IT!!! SHE DID IT!!! WHOO!!!"

Sunset looked at herself in amazement. "Oh my Celestia..." She looked at the Kaenken Rekka. "Well, let's see what we can do." She got in a battle stance and ran forward, starting to fight the Golem Megid with Flash's help, flipping around almost expertly and dodging any attack that came at her or blocking it as she utilized the martial arts she was experienced in for battle, easily keeping up with the Megid.

Flash flew over to Sunset and landed in her hand then, giving her dual swords to fight with as she slashed the Megid back, jumping in the air to avoid an attack before she blocked another and pushed it back, stumbling slightly. "No way is this world falling to threats magical or otherwise!" She sheathed Kaenken Rekka again and activated Saikou's finisher. "Saikou Hakkou!" "The ending of this new story... is mine to decide!" She pressed the trigger and drew out Kaenken Rekka again. "Hissatsu Dokuha! Rekka Battou! Dragon!" "Kougou Ryuuhazan!" "Rekka Issatsu Giri! F-F-F-Fire!" She delivered a cross slash of golden light and red flames that impacted against the Megid as she turned and held both swords at her side while the Megid fell and exploded.

End Theme

Trixie Lulamoon fell out of the explosion and landed on the ground unconscious as the Alter Ride Book landed beside her.

Sunset turned and picked Trixie up worriedly, letting Flash float beside her as he spoke up, "She's gonna need the infirmary for any damage issues."

She nodded to him and passed Trixie off to Lyra Heartstrings and Bon-Bon, who rushed Trixie inside quickly.

Sunset turned to her friends, who were cheering for her and Flash with Fluttershy continuing to shout, "KAMEN RIDERS!!! THEY'RE KAMEN RIDERS!!! WHOO!!! YEAH!!!"

Sunset dehenshined and looked at Flash as he also changed back, asking him, "Kamen Riders?"

Flash smiled and shrugged, responding, "So Flutters knows her heroes better than me."

Sunset nodded before she was tackled in a hug by Fluttershy and Pinkie, falling to the ground with a grunt of pain.

Applejack walked over and smiled as she helped Sunset up and spoke, "Well then, I guess we're gonna have to get you some sword training in."

Rarity smiled as she looked at Applejack and told her, "Maybe I can help with that, darling. I have several years of fencing experience under my belt, relatively speaking. I'm sure I can train them to perfect shape in no time."

Rainbow sighed softly and rolled her eyes before she spoke with a smile, "Well, I guess this was one magical adventure that none of us were gonna expect, but it's an AWESOME ONE!!" She threw her fists into the air with a cheer, being joined in by the others moments later. This certainly looked to be a new epic adventure.

Author's Note

Wow, my first true Kamen Rider and MLP crossover. I'm gonna try and keep up on this one because Saber is one of many Rider series I am looking forward to watching, along with the current Rider, Revice. I know I'm still working on Beyond the Grid, but I'm not too certain about finishing that one, so if you guys want me to finish it, please let me know. I'd love to hear your thoughts. And please read and review this story as well!

Also, This means a flashback or a dream sequence, 'this means a thought', this means it's a book title, this means the Rider or monster is talking, this means the theme is playing or ending, this is for the Driver and Ride Book announcements, "this means someone is on the other line in a phone call", and there will be horizontal lines showing that the scenery will be shifting from place to place and timeline to timeline.
