Jaune Arc stumbled back as Falchion slash him out of his armor.
"So is that all of the amazing Saber?" Falchion rested his sword on his shoulder.
"I understand how strong your feelings are." Jaune started to get back up. "But then, if you're that strong, why couldn't you change your way?!"
"A human like you, can't possibly comprehend the despair of us Faunus!" Falchion shouted.
"FYI, Adam but humans can despair too," Jaune said in a matter-of-fact tone. "But if there's one thing humans and Faunus are similar is that we still have the power to rise up, again and again!"
"Yeah! I will never give up on anybody, not even myself!" Neptune says as he gets back up.
"If we bail now… the world will end." Qrow started to get back up as well. "I'm not letting the Grimms have this world, and I'm not letting you have it either."
Flynt stood up too, "My Holy Sword says we shouldn't give up either."
"As Ace Operatives and wielders of a Holy Sword, it is our duty to protect everyone in Remnant!" Clover declared as he and Winter stood back up as well.
"To defeat those who bring harm to our world!" Winter added in.
"You always held great power, adam…" Blake got back up. "But all you use is for nothing but destruction to both your people and humans!"
"She's right, Mr. Taurus, people make up the world. As people change, so does Remnant!" Ozpin agreeing with Blake
Now with his fellow swordsman voicing out what they believed in, Jaune stares at the Immortal Swordsman, "I believe in the strength of everyone in Remnant. Faunus and humanity's feelings will create this world, a new future!"
Coming out of nowhere was Ren as he held both two Holy Swords, Ikazuchi and Kurayami.
"I believe in Jaune and myself," Ren says. "We can change the future!"
"Renny!" Nora is happy to see Ren's arrival.
"I'm glad for you to be here, Ren," Jaune stated as he smiles at Ren with gratitude for showing up.
"Nonsense." That was all Falchion said.
"For years… you decided to wallow up in your own pain and despair!" Jaune berated the phoenix Rider. "You never once asked for help! You just let people"
"Shut. Up." Falchion growled.
"He's right, we may never experience the trauma you'd faced but I'm sure we'll create a future even you don't know!" Ruby declared before smiling at Jaune.
Jaune smiled back before facing Falchion and charging towards the orange Rider without even transforming into Saber. Jaune raised his sword up as Falchion took a swing, Rekka's blade glowed and was engulfed in flames as Jaune blocked Falchion's strike. The Saber suit made a brief appearance around Jaune as the young swordsmen let out a hard strike at Falchion's abdomen.
Falchion stumbled back as a glowing slash mark appeared on his armor.
"This shouldn't be possible, Kyomu gave me an immortal body!" Falchion shouted as he de-henshin back to the Bull Faunus. "So this is the combined power of Faunus and humanity's feelings… their power…" Adam turns to face not Jaune but at Ruby. Adam grins before laughing maniacally. "Maybe I'll never see the future you will create…" Adam then stabs his Kyomu into the ground before his body starts to turn into soot. "But I shall see to it." And with that main agonist leader of the White Fang, the Immortal Swordsman, was no more.
With Falchion gone, all that was left was Kamen Rider Solomon, who merely enjoyed the scene he happened to watch.
"That was quite an amusing display, but you are now too late," Solomon says, behind him, the giant grimoire was sucking the world up as turning the day into night. "Now bear witness! This is how the world ends!"
Solomon closes the Omni Force Wonder Rider Book, opens the front cover again as he presses the button on his Dooms Driver Buckle, twice.
OMNIBUS LOADING!
A giant version of the Omni Force Wonder Ride Book appears in the air and summons a giant copy of Caladbolg from its pages.
"The world is no longer in need of Swordsmen," Solomon says.
The giant Caladbolg then performs a downward slash into the Magic Knight Swordsmen.
SOLOMON SLASH!
As Caladbolg went down to kill them, Jaune held out Rekka to block the attack while Ruby dashed forward to remove Kyomu from the ground and blocked the giant Caladbolg alongside Jaune.
"Your sword is weak!" Jaune shouted at Solomon.
"What did you say?"
Jaune and Ruby used all their strength to destroy the giant Caladbolg.
"He said your sword is weak!" Ruby repeated what Jaune said.
Jaune glared at Solomon, "I don't feel a damn thing coming from your sword!"
"Why the hell should that matter?!" Solomon shouted back.
"Huntsmen and Swordsmen… We fight while bearing our feelings into our weapons!" The rest of Kamen Riders and allies began to stand behind Jaune, with their hands gripping their Holy Swords. "And you don't have any!"
Soon a golden bird began to flutter next to Ren before it transformed into Li Ren, Lie Ren's father.
"Dad…" Ren, happy to see his father.
Ren handed Kurayami to Li who grabbed the Holy Sword and nodded to his son.
"Surely you jest!" Solomon began to laugh. "Feelings you say? Those things do not amount to anything in the face of absolute power!"
"Our feelings… will create the future!" Jaune declared.
Jaune and his fellow Huntsmen's Holy Swords began to glow one by one.
REKKA! NAGARE! IKAZUCHI! GEKIDO! HAYATE! SUZUNE! KURAYAMI! SAIKOU! NOROSHI! KAIJI! KYOMU!
They all route their Holy Sword to the sky, Li disappears when he sends Kurayami to the sky with the other fellow Holy Swords.
"Wait, where are they going?!" Ruby asked.
"In response to our feelings, they all decided to create something new," Flynt answered her.
"To create what?!" Yang asked as well.
"Just wait and watch girls," Ozpin told the sisters as they all looked up to the sky.
They all see the united their power as the Holy Swords formed a tree diagram up in the stars.
"What is this?! What is happening?!" Solomon shouted to no one.
"When the one destined to stoke the fire of the first Holy Sword forged by human hands appears…" Flynt started to explain.
"A new Holy Sword with the power to connect the stars and lead this tale to its conclusion will be born." Ozpin finished the explanation.
All Holy Swords unite their powers to form the latest of Holy Swords, Haouken Xross Saber.
The Holy Swords and meteors fell from the sky as they fell from the sky. The Holy Swords fell from onto their owners' hands as Haouken Xross Saber fell upon Jaune's hand.
HAOUKEN XROSS SABER!
Jaune was in awe as he inspected his new Holy Sword, a sword that could hold the power to defeat Solomon.
"So the sacred sword that rules overall has been born," Solomon commented. "But no matter… the world has come to the end!"
"No, it is not over," Jaune glared at Master Logos. "I'll decide on how this story ends!"
Jaune jammed the Holy Sword into his Swordriver before taking out the Brave Dragon Wonder Ride Book.
BRAVE DRAGON!
He then entered the Wonder Ride Book into the Swordriver's right slot.
The Swordriver and Haouken began to let out a waiting tune.
Jaune held onto the hilt of Haouken making everyone stand by for whatever is going to happen. After a few more seconds Jaune pulled out Haouken from his Swordriver.
SEIBA BATTOU!
The giant version of the Brave Dragon Wonder Ride Book appeared behind him and opened letting out Brave Dragon. There was also the glowing replica of the Holy Swords rotating around Jaune.
"Henshin!" Jaune shouted as did an X slash while Brave Dragon skin changed from red into purple with the design of the stars on it.
HAOUKEN XROSS SABER!
Brave Dragon started to swirl around Jaune before forming his armor.
SŌSEI NO JŪJI!
The glowing replicas of the Holy Swords started to pile onto Jaune.
KIRAMEKU HOSHI-TACHI NO KISEKI TO TOMONI!
The X slash returned, forming the visor for Jaune's new armor.
KEDAKAKI CHIKARA YO YŪKI NO HONŌ! XROSS SABER! XROSS SABER! XROSS SABER!
Jaune was finished with his transformation as he was glowing and had the power of a new Holy Sword.
MAJIWARU JŪ-PON NO KEN!
He wore a midnight blue bodysuit alongside a midnight blue glove on his left hand while his right glove was white with yellow fingers. His armor had an azure-space coloring with shiny stars on his body armor, armored collar, left smooth shoulder pad, forearm, and the armor from his knees to his boots. On the right side was a trench coat, a dragon with yellow eyes, his forearm was armored with jagged spikes as well as his elbow with the coloring being azure with shiny stars on them. His helmet was black with his faceplate with the azure-space coloring with shiny stars on it as well. The X had a more white coloring as well as his visor and in the center of his forehead blue blade-like horn that resembled Haouken Xross Saber.
With the power of Haouken Xross Saber, Jaune became the galaxy swordsman, Kamen Rider Xross Saber!
"Amazing!" Weiss looks at the sword with awe.
"Woah, they created a new sword," Yang commented.
"Jaune is now glittery and shiny!" Nora shouted out.
"Just watching him is making my blood boil with excitement!" Flynt shouted.
"I'm the one who will create!" Saber declared.
Saber presses the ring emblem, the Great Cirxross.
HAOU HISSATSU READ!
Saber shifted the emblem to the last four elements for a finisher.
KIDOKU JUU SEIKEN!
He then slides the emblem back to the hilt of the sword.
HAOU XROSS SEI RETSUZAN!
Light blue energy and multicolored sparkles surround the Haouken Xross Saber before Saber performs a violet energy slash.
Copies of the ten Holy Swords then appear in a line above Saber alongside their respective emblems. Saber then swings his sword again, causing the ten Holy Swords to fly into the air. Far above the earth, the Holy Swords lineup while images of their users appear behind them before separating.
Each Holy Sword travels to a different part of the world, with Kaenken Rekka returning to Saber. Saber charges the Haouken Xross Saber with rainbow energy and performs a downward slash.
At their destinations, the Holy Swords, with the exception of Kaenken Rekka, destroy their targets while images of their users appear once again and mimic the attacks. Finally, Saber swings the Haouken Xross Saber, causing the copy of Kaenken Rekka to mimic him and deliver a slash to the enemy while an image of Saber in his Brave Dragon form performs the same attack.
Solomon growled at the destruction of giant grimoires before turning back to face Saber.
"I will create the present!" Saber declared once more.
Saber docked Haouken Xross Saber into his Swordriver and pressed the weapon's trigger.
HAOU HISSATSU DOKUHA!
Saber takes Haouken out of his Swordriver.
SEIBA BATTOU! HAOU ISSATSU GIRI! SABER!
Blue sparkles surround Saber before the emblems of the ten Seiken appear on the Haouken Xross Saber and the sword is surrounded by magenta energy.
Saber then swings the sword, creating a slash of rainbow energy that flies around and leaves behind multicolored sparkles. Saber continues performing graceful movements with his sword, creating more rainbow energy that repairs the damaged surroundings, with rubble floating and reconstructing what it broke off of.
Everyone looked in awe at what Saber just did.
"Vale, it's back!" Sun looked around him.
"This must be the power of the Ultimate Holy Sword," Pyrrha stated.
"A sacred sword with the power of creation…" Solomon started giggling insanely. "Truly wonderful!"
Solomon closes the Omni Force Wonder Rider Book, opens the front cover again as he presses the button on his Dooms Driver Buckle, twice.
OMNIBUS LOADING!
"The sacred sword and this world will all be mine!" Solomon raised Caladbolg straight to the air.
SOLOMON SLASH!
A giant version of the Omni Force Wonder Ride Book appears in the air and summons numerous giant copies of Caladbolg, some of which transform into their mecha mode and land on the ground.
"I will protect this world from you and any other threats!" Saber declared.
Saber shifted the emblem to the first three elements of Haouken and pressed the sword's trigger aiming for the chosen element.
REKKA! NAGARE! IKAZUCHI!
Saber returned the emblem to its starting position on the sword's hilt.
KIDOKU!
Saber shifted the emblem right back up but to the second three elements and pressed the sword's trigger aiming for the chosen element.
GEKIDO!
Saber returned the emblem to its starting position on the sword's hilt.
KIDOKU!
He then presses his weapon's trigger.
IKAZUCHI! GEKIDO! XROSS GIRI!
A giant construct of the Dogouken Gekido appears above Saber before he performs a downward swing.
GEKIDO!
Causing the construct to mimic his movements and deliver a downward slash to the mechas, destroying it.
Saber then points the Haouken Xross Saber upward to the sky, causing numerous copies of Raimeiken Ikazuchi to appear along with lightning.
IKAZUCHI!
The lightning converges into a single large lightning strike that shocks a second while the swords rain down on King of Solomon mechas.
Saber shifted the emblem right back up but to the second three elements and pressed the sword's trigger aiming for the chosen element.
GEKIDO! HAYATE!
Saber returned the emblem to its starting position on the sword's hilt.
KIDOKU!
Saber shifted the emblem right back up but to the second three elements once more and pressed the sword's trigger aiming for another chosen element.
GEKIDO! HAYATE! SUZUNE!
Saber returned the emblem to its starting position on the sword's hilt.
KIDOU!
He then presses his weapon's trigger.
HAYATE! SUZUNE! XROSS GIRI!
Saber flies into the air as an energy construct of the Fuusouken Hayate appears above him and converts to its Shuriken Mode.
HAYATE!
Saber then sends the Fuusouken Hayate flying forward in a burst of green wind, with the weapon leaving behind green afterimages. It then splits into its Nitouryu Mode and slashes two mechas from behind.
An energy construct of the Onjuuken Suzune then appears in front of Saber and converts to its Gun Play Mode.
SUZUNE!
An energy ball appears in front of its barrel before it blasts several enemies with a wide, sustained beam of pink energy destroying more mechas of Solomon.
Saber shifted the emblem to the first three elements of Haouken and pressed the sword's trigger once.
REKKA!
Saber returned the emblem to its starting position on the sword's hilt.
KIDOKU!
He then presses his weapon's trigger.
REKKA! XROSS GIRI!
An energy construct of Kaenken Rekka appears above Saber before splitting into five copies that encircle him. The swords then start spinning while covered in fire, blocking the mechas' attacks.
Saber docked Haouken Xross Saber into his Swordriver and pressed the weapon's trigger.
HAOU HISSATSU DOKUHA!
Saber takes Haouken out of his Swordriver. Saber's body then began to be surrounded by blue energy with cyan and magenta stars appearing around him.
SABER BATTOU! HAOU ISSATSU GIRI! SABER!
Saber then performs a 360-degree cyan and magenta energy slash that destroys nearby enemies, leaving behind rainbow explosions and an energy wave that resembles a galaxy. The energy wave continues traveling outwards and is capable of damaging the remaining mechas and Solomon who was standing outside the range of the initial attack.
Solomon tried to hold the attack with Caladbolg, but Saber's attack was too powerful and threw Solomon out of the area.
With that done, Saber closes his Wonder Ride Book and removes it from his Swordriver, having him de-henshin.
"You did it!" Ruby jumped onto Jaune, hugging him before letting him go.
"That was amazing, Jaune!" Pyrrha ran to Jaune, hugging him as well before letting him go. "I knew you could defeat Master Logos."
"Thanks" Jaune being modest rubs the back of his head.
"Not just Vale, but any location that Logos targeted are back to normal as well!." Nora showed her scroll to everyone.
"You were able to stop the apocalypse, man!" Neptune high-fived Jaune.
"I'm impressed you were able to change the future once more," Qrow gave Jaune an impressed smile.
"It's because of your feelings I was able to save Remnant," Jaune gave everyone an appreciative smile.
Those who weren't around him just stared from the sidelines.
"Good job Jaune, I knew you could do it." Blake smiled before losing it and stared at her own team. "But I still have things I need to do before I could join you." And Blake left the scene.
"Should we go to them, Clover?" Winter asked Atlas' Ace-Ops' leader.
"No, we need to report to General Ironwood and to find Issac, he's still alive somewhere," Clover responded.
Winter nodded and both Atlas Huntsmen left the area.
Lie Ren watched on with pride for Jaune's achievement, "Father… Jaune was able to change the future once more." Ren says before leaving the scene.
With Jaune's friends complimenting him, Ruby notices something, she looks around her searching for something.
"What is Ruby?" Her sister asked what's wrong.
"Um, where is Kyomu?" Ruby asking the big question.
Everyone's eyes widened as they looked around to see if they could find Mumeiken Kyomu not knowing it was already taken.
~/~
Elsewhere in the Land of Darkness, the witch called Salem was watching over the birth and power of Haouken Xross Saber.
"Hmm, a sword of creation…" Salem observed Jaune and Haouken. "To think a weapon with such power can be created." Should she try to send her subordinates and Grimm after the Haouken Xross Saber and Jaune? "No, I still need to observe its power."
All Salem has to do is wait, and hope it won't regret not acting right now.
AN: Yes, Ozpin is Saikou, just think of Ozpin's soul being removed from Oscar and being placed in Kougouken Saikou. Adam is not an ancient immortal but a guy who happened to discover Mumeiken Kyomu and become Falchion. Here are the other Riders; Jaune is Saber, Neptune is Blades (It's an AR World, of course, the characters will be different), Lie Ren is Espada, Qrow is Buster, Blake is Kenzan, Flynt Coal is Slash, Li Ren is Calibur, Winter is Sabela, and Clover Ebi is Durendal.
For now, this was the second one I'd finish because it is difficult not to make the one-shots too similar, we'll be going back to our regular random one-shots.
