Chapter 14: The Rider War: The Battle

Natsumi watches with a look of concern and worry, aware what comes next will be the start of her nightmare. Her only hope is Tsukasa to change it as she grips on his camera around her neck.

''HENSHIN!" Everyone Rider shouts all except Hibiki who just taps the Onsa's forks on the side of his hand, vibrating before moving it over his head. Each of the other rider belts trigger as their belts announce except Yusuke, Shoichi and Hibiki. ''ADVENT! COMPLETE! TURN UP! CHANGE BEETLE! SWORD FORM! GABUU!''

''KAMEN RIDE!'' Both the Decadriver and Diendriver announce as Tsukasa wipes his hands together before he and Kaito transform into their rider forms. ''DECADE! DIEND!''

Both Yusuke transform into Kuuga but the real one turns into the more improved Rising Mighty, the more power-up form with golden trimmings and extensions.

Decade takes on a strong pose as Diend slides a card into his Diendriver, loading it up.

''Shall we, Tsukasa-san?'' Diend questions his rival and Decade responds by charging forward. A.R. Kuuga follows suit as does Absol. Diend lets out a chuckle taking aim and fires.

''KAMEN RIDE! RIOTROOPERS!'' The Diendriver announces as the blast becomes multiple Riotroopers, blasting at the transformed riders who brushes off their attacks as they too charge. The riders charge as the Riotroopers get in their way with Diend engaging a few at a time while both Kuugas confront each other. Absol barks, engaging Kiva and Blade.

Decade, though, finds himself clashing fist up against Faiz. The two push the other with their fists but Decade's overpower Faiz as he summons the Auto Vajin, firing at Decade. Decade repels the blasts with the Ride Booker sword form as he switches into gun form and fires a barrage of blasts, destroying the battle robot.

''Guess you're up first, Nekojita-san.'' Decade declares taunting Faiz who responds harshly. ''Funny aren't you.''

Decade looks at him before speaking up trying to sound honest. ''Takumi, I learned a lot from your A.R. self. Don't assume I'll let my feelings change this.''

Faiz was glad he felt that way replying. ''Good, I didn't want this to be harder for either of us.''

Thinking of Mari and his friends on his world, Takumi- Faiz declares proudly as he flicks his right wrist on the side. ''I won't hold any punches!''

Decade scoffs as he charges forward. Faiz comes charging too as the two riders clash fists. Their attacks push them back as Faiz comes swinging hard and fast but Decade easily moves around the attack, easily dodging around the attacks.

Decade reads through Faiz's street fighting skills like a book. He then responds by swiping a punch from Faiz before kicking Faiz backwards hard on the chest. Faiz staggers back as Decade comes at him and swings him with a barrage of punches, easily smacking him back harder.

Not given a choice as he breathes, Faiz slides the chip of his wrist watch into his belt.

''COMPLETE!'' The Faiz Driver announces as Faiz changes into his Axel Form. Decade scoffs expecting him to do that pulling out a Rider Card.

''I was wondering when you would do that.'' He states as he slides the card into the Decadriver. ''ATTACK RIDE!''

Faiz quickly activates his time stop watch. ''START UP!''

Faiz Axel runs at Decade with crazy speed but before he could reach him, Decade pushes the handles of his belt as the Decadriver announces. ''INVISIBLE!''

Immediately Decade turns invisible as Faiz Axel hits where he assumed he was but hits nothing but air to Faiz's shock. ''Nani!''

Suddenly he feels a kick striking his back. Faiz turns and dashes fast but hits nothing again. And then feels a fist on his face as he tries kicking instantly fast. Again, nothing but air.

''ATTACK RIDE!'' Faiz soon staggers hearing the Decadriver's voice turning to see Decade becoming visible but multiplying into 5. ''ILLUSION!''

Each Decade wipes their hands before walking slowly at him. Faiz dashes at them as time ticks down, quickly disposing of 4 of them with insane unseen speedy punches or kicks, destroying only the illusions. Faiz comes towards the real Decade with great speed and swings a punch… until the Faiz Stopwatch announces. ''THREE! TWO! ONE! DEFORMATION.''

In those exact moments Faiz Axel form ended and reverted back into the regular Faiz form with Decade instantly catching the fist. Faiz is taken back, realizing Decade was toying with him to run out of the time limit.

Decade then kicks Faiz twice before swinging a strong thrusting punch, sending Faiz flying backwards onto the ground.

''Had enough?'' Decade taunts his opponent while wiping his hands. Faiz pants getting up but pulls out a large white-red colored briefcase-like giant device.

''Now you'll see us Riders go all out!'' Faiz declares as he slides the Faiz Phone into the handle-like weapon, announcing. ''AWAKENING!''

He quickly presses the 5 dial 3 times as the device announces. ''STANDING BY!''

A beam suddenly comes down from the sky and hits Faiz, transforming the rider into Faiz Blaster Form as he unfolds the briefcase into a massive rifle-like blaster weapon, wielding it like a sword by its inner handle.

Decade stares at the final form, muttering out. ''Faiz Final Form.''

Faiz walks towards Decade as Decade thrusts a card into his belt and aims with his Ride Booker.

''ATTACK RIDE! BLAST!'' The Decadriver announces as Decade fires multiple magenta colored energy blasts but the attacks hit and do not faze Faiz Blaster as he presses a few dials.

''FAIZ BLASTER DISCHARGE!'' The Faiz Phone announces as the shoulder pads turn around and become small cannons that fire multiple energy blasts at Decade, covering him in smoke.

''ATTACK RIDE! ILLUSION!'' The Decadriver announces as multiple Decade emerges from the smoke, all coming towards Faiz as he presses a few buttons on his blaster. The weapon suddenly extends and becomes a sword, announcing it. ''BLADE MODE!''

The Decades wield their Ride Booker sword forms swinging at Faiz who easily counters with one swing and repels them all at the same time. Each Decade comes at each side of Faiz, swinging their swords but Faiz swings around once more, releasing a red pulse wave that destroys all the copies and sends the original backwards.

Decade grunts getting up dunking a card into his belt, pushing one of its handles.

''ATTACK RIDE! SLASH!'' The Decadriver announces as Decade swings his sword and fires a magenta energy slash but Faiz cuts the attack in half with his weapon before pressing a dial.

''FAIZ BLASTER TAKE OFF!'' The Faiz Gear announces as Faiz takes off from the shoulder cannons like a jet back, flying downward at Decade who just barely rolls away as the Faiz Blaster cuts through one of the destroyed cars with ease.

Decade turns to see Faiz Blaster descending, knowing well he can't hold anymore punches.

''Then…'' Decade begins to say, holding up a Super Rider Card and tosses it into the Decadriver, pushing its handles.

''SUPER FORM RIDE! FAIZ AXEL!'' The Decadriver announces as Decade transforms into Faiz Axel, wiping his hands together as he declares. ''This is how you use Axel.''

Faiz Blaster comes at him flying as Decade-Faiz turns on the stopwatch. ''START UP!''

In the fast speed, Decade-Faiz dashes at Faiz while attaching the Faiz Pointer onto his right ankle and resumes kicking Faiz Blaster so hard it launches him into the sky. Faiz Blaster activates his jetpack as he quickly presses 3 dials.

''EXCEED CHARGE!'' The Faiz Gear announces charging the blaster into a red energy beam. Decade-Faiz quickly thrusts a card into his belt and pushes his belt as he leaps into the sky at Faiz Blaster.

''FINAL ATTACK RIDE! FAIZ!'' The Decadriver announces as Decade-Faiz comes at Faiz with an upward Rider Kick. Faiz Blaster dashes downward at Decade and swings his energy bladed weapon as Decade summons the energy drill and both attacks clash. Sparks and beams of red energy spin around the two colliding attacks, tearing through a few clouds and the ground. Natsumi takes over with Dragonic protecting her.

Decade-Faiz tries kicking forward but Faiz pushes back harder with his sword. Cracks begin to shown on both the bladed beam and drill but Faiz Blaster manages

Decade falls backwards down on the ground, grunting as he reverts to his standard form. Faiz Blaster quickly descends to slash him. Decade tries getting up to see the rider coming at him.

''KAMEN RIDE! FAIZ!'' Faiz Blaster turns and immediately gets a punch across the helmet face by Faiz, one summoned by Diend as he spins kicks Kiva back.

''Tsukasa-san! Use him!'' Diend tells Decade who proceeds to dunk the Final Form Ride card. He runs over to the Faiz copy and taps his back. The fake Faiz starts to transform as the Decadriver announces. ''FINAL FORM RIDE! FAIZ BLASTER!''

Decade turns fast and catches the transformed Faiz in his possession. Faiz Blaster sees this and takes aim with his own blaster. The two fire a burst of red energy but Decade tears through his. Faiz Blaster dodges it fast, just barely.

''Let's settle this.'' Decade declares tossing the Final Attack Ride card upward and falls inside the card inserter of his belt. ''FINAL ATTACK RIDE!''

The massive weapon begins to charge up. Faiz pulls out the Faiz Phone and dunks it into the Faiz Gear before tossing the blaster away.

''EXCEED CHARGE!'' The Faiz Gear announces as Faiz takes on his crouch pose, flicking his right wrist as he then charges forward. He leaps forward into a Rider Kick, manifesting his energy drill right at Decade who fires. ''FAIZ!''

The giant Faiz Blaster fires a powerful red energy blast clashing against the energy drill. Faiz yells out kicking forward with all of his strength and yet it isn't enough as the blast rips through the drill and consumes him instantly. Faiz braces himself as the blast tears him apart.

The last thing Faiz- Takumi could recall in his final moments was the friends who accepted him for who he was.

''Sorry… everyone.'' Takuma expresses mentally before he screams as the blasts destroy him completely.

Natsumi watches this with a sadden expression, looking down depressed.

Decade wipes his hands declaring. ''One down.''

Both opposing Kuugas clash form to form though most of the clashes went to the original's favor. Diend blasts multiple riders back while summoning more fake riders.

Absol engages Den-O who yells at her biting his arm. ''GET OFF ME DOG ASSHOLE!''

Absol does release her fangs off him but not before using Night Slash, sending him flying backwards as he yelps in agony.

Decade ignores this as his focus is on Agito approaching him.

''Guess you're up, chef farmer.'' Decade proclaims pointing his finger at him. Agito looks back at him, breathing, before taking on a determined fighting pose.

''I don't want to fight you Tsukasa-san but I can't let our worlds to be destroyed!'' Agito proclaims not going to fail his friends in his world or fail the memory of his sister. He comes charging swinging but Decade repels the punch swings with a strong kick to the gut, grinding it with his knee cap before launching him backwards hard.

Agito is kicked into the ground as he gets up and immediately gets uppercut by a slow walking Decade, tossing him backwards hard. Agito manages to land on his feet, coughing up partly before slamming both sides of his belt waist and transforms him into Agito Trinity with both weapons.

Decade pulls out the Ride Booker and he swipes the back side of his sword before charging forward. Agito charges back at the two clash weapons. Even against the double bladed staff and sword, Decade was able to expertly parry both swings with his better swordsmanship.

''Then try to fight me!'' Decade tells Agito off as he kicks him and dunks a rider card into his belt.

''ATTACK RIDE! SLASH!'' The Decadriver announces as Decade swings and fires a powerful magenta energy slash. Agito tries to counter it with both his weapons but the attack explodes and destroys both weapons. Agito is tossed rolling on the ground.

Breathing heavily, Agito pulls himself up realizing he needs to win no matter what it takes. For the sacrifices and hardships as Shoichi that he went through, he can't lose!

''I went through a lot and lost many people. That's why…'' Agito begins to declare as he breathes deeply and slams both sides of his belt again. Agito's belt changes as he becomes Agito Burning Form. He looks up at the bright sunlight as his form begins to radiant, changing into the bright Shining Form.

''That's why I can't give up!'' Agito Shining declares, manifesting his new white-silver, red tip double ended blade before splitting them apart into two swords.

Decade scoffs as he holds up his response to this power and dunks it into his belt.

''SUPER FORM RIDE! AGITO BURNING!'' Pushing the handles of Decadriver, Decade transforms into Agito Burning still wielding the Ride Booker. Decade-Agito comes charging as Agito Shining stands his ground and soon both riders cross blades, sparks flying as Decade swings his faster but Agito was much faster, repelling each swing insanely fast before roundhouse kicking Decade back.

Decade ignores it holding up a card and tosses it into his belt.

''FINAL ATTACK RIDE! AGITO!'' The Decadriver announces as Decade comes charging, throwing his free hand forward as a fiery magma-like fist. Agito Shining responds by swinging one of his swords at him and both attacks clash but the shining sword cuts through the attack and sends Decade backwards. He slams his feet on the ground to not fall back as he reverts back to normal Decade.

''Still need help huh?'' Diend asks, watching this with a taunt as he evades Blade's swings and loads the Diendriver with a card. He takes aim at Agito Shining and fires a shot at it.

''KAMEN RIDE! AGITO!'' The Diendriver announces as the energy shot coming at Agito who turns into a summoned Agito, kicking the real one back.

Decade scoffs for the save as he pulls out a card and dunks it into his Decadriver. He runs up to the fake Agito and slaps his back as the fake rider starts to transform.

''FINAL FORM RIDE! AGITO TORNADOR!'' The Decadriver proclaims as the fake Agito becomes the large hoverboard. Decade hops on it as the hoverboard speeds around Agito Shining. Agito watches taking on a pose with his swords at the side. The hoverboard moves to make a far U-turn as Decade dunks a card as he takes on a swordsman striking pose.

''FINAL ATTACK RIDE! AGITO!'' The Decadriver announces as the hoverboard moves at top speed at Agito Shining before stopping dead on and this launches Decade forward with great speed but instead of a rider kick, he swings the Ride Booker sword at him. Agito Shining counters with both swords but Decade moves way too fast and the force of said speed allows his weapon to cut through Agito's and slashes through him.

Agito staggers as the slash wound starts to crack across his body. He coughs, not expecting that turn around and tells himself… apologizing to the young girl he considered close to him. ''Sorry Mana… I guess I won't be coming back. Heh, I should have made you and the others my last dish…''

''HAAAYYYY!'' Agito screams as he explodes into a shining bright light. Decade breathes twirling and slashing the air.

Decade now turns his head, facing Hibiki who looks ready to fight.

''Guess it's my turn.'' Hibiki states looking at where Agito perishes and looks back at Decade who scoffs.

''Warrior's death. You're dying, aren't you?'' He questions Hibiki, starting to realize why Hibiki is going through this fight. Hibiki snickers, responding. ''Something like that. I guess I've been dying for a while.''

Decade stares at him silently as he holds his sword forward. Clapping his hands to warm up, Hibiki declares determined. ''Alright young man, show me your resolve.''

Decade oddly snickers back as he responds back. ''Gladly… Hitoshi.''

Hibiki staggers that he knows his name and snickers at this young man. He twirls his drumstick weapons and comes at him. Decade scoffs swiping the backside of his sword and comes at him.

The two clash as Hibiki swings his weapons with great speed and strength but Decade parries the strikes and then back kicks him hard. Hibiki lets out a battle cry as his drumsticks lit up in flames and throws them. Decade rolls around the attacks as he had dunked a card into his belt, pushing a handle forward.

''ATTACK RIDE! SLASH!'' The Decadriver announces as Decade comes swinging, slashing the fireballs before coming at Hibiki and slashes through his weapons, destroying them. Hibiki backs away fast and looks at his destroyed drumsticks, tossing them.

''Last stand then.'' Hibiki declares as he breathes deeply as he pulls out a silver, deep crimson bladed, the Armed Saber. He breathes holding it as he uses his left hand to touch the bottom hilt which has a button and then flips the guard revealing a speaker. Hibiki soon speaks through it. ''Armed Hibiki.''

Decade watches as a build-up of aura courses through Hibiki's body as many different Animal Disks surround him, becoming armor for him. He soon erupts in flames and becomes Armed Hibiki.

''So that's an Oni's full potential.'' Decade says as charging at Hibiki. Armed Hibiki watches as Decade performs multiple slashes but none faze the Oni. Hibiki then lets out a shout through the speaker, revealing a powerful red burst of energy that hits Decade. Sparks fly out from the rider as Decade is launched backwards hard.

Decade, getting back up rough up, breathes pulling out a card and slides it into his belt, pushing its handles.

''SUPER FORM RIDE! HIBIKI KURENAI!'' The Decadriver announces as Decade wipes his hands as he's consumed in crimson flames before waving his arm, revealing himself in Hibiki's super form.

Decade-Hibiki comes charging swinging his Ride Booker engulfed in crimson flames as Hibiki parries with the Armed Saber, both flaming swords clash in a fiery burst that pushes them back. They came back at the other, swinging their attacks as they dodge the other. They continue trying to strike the other until Hibiki steps back and he swings his sword unleashing powerful fiery, energy slashes. Decade cuts through them as he holds up a card and dunks it into his belt.

''FINAL ATTACK RIDE! HIBIKI!'' The Decadriver declares as Decade comes charging as the Ride Booker erupts in even more fiery crimson energy from the blade and swings it at him but Hibiki breathes and focuses as his blade erupts in massive flames, extending long. Hibiki swings forward as the extended blade grows and clashes flame to flame. However Hibiki's were much stronger as his slash cancels Decade's and hits him backwards. The rider reverts back to regular Decade, hitting the ground. Hibiki breathes as he raises his sword forward as the flames ignite once more.

''KAMEN RIDE! HIBIKI!'' Hibiki suddenly turns and dodges multiple fireballs from the fake Hibiki that Diend summoned. Decade runs up to the fake's side as he dunks a rider card into his belt and then taps the fake's back.

''FINAL FORM RIDE! HIBIKI ONGEKIKO!'' The Decadriver announces as the fake Hibiki transforms into the massive falcon-like Animal Disk. Decade hops on the mechanical bird taking flight and coming at Hibiki. Armed Hibiki focuses and swings releasing powerful extended flame slashes but the bird dodges around the attacks, descending upward.

Decade jumps off the giant mechanical bird as it descends towards Armed Hibiki who swings his extended fiery sword at the creature. Decade, still in mid-air falling, dunks a Final Attack Ride, pushing the handles of his belt.

''FINAL ATTACK RIDE! HIBIKI!'' The Decadriver announces as the red bird Hibiki becomes a massive Animal Disk, smashing through the long fiery sword swing and slams itself on top of Armed Hibiki. He grunts trying to get the Animal Disk off him until he hears a battle cry. ''HAAAYY!''

He looks up and sees Decade, descending rapidly right on top of him with a Rider Kick and soon enough the kick connects on top of the disk. Decade slams his Rider Kick onto the large Animal Disk, vibrating a powerful tremble as it glows and explodes on impact.

Armed Hibiki screams in pain at first… as he thought of his comrades, his friends… his mentor, heck even Kiriya and the clueless but now strong young man Asumu who will become someone great, someone greater than him.

''Boy… Asumu…'' Hibiki starts telling him, hesitating to be honest about it so he wishes while doing his salute. ''You'll become a great man, better than this Oni.''

Decade lands back as the summoned Hibiki vanishes and watches as the real one is consumed by his own purple flames. He reaches out to him, but the flames would not let him move anymore.

''Listen proud to your voice, Tsukasa! Be who you are…'' Hibiki begins parting his final words as the flames turn him into ashes. Decade watches him as the proud Oni rider tells him, giving him his final hand salute. ''No matter what any world sees of you… Be who you are…''

And with that Hibiki is burned by his own flames, becoming fiery ashes returning himself to nature.

''…'' Decade didn't say a word, looking up at the sun shining for the once kind hearted man.

''It's not fair!'' Decade turns by the complaining of Ryuki, so frustrated by these pointless fighting and deaths. For Shinji who in his world he's been told countless times that Riders who fight for their selfish or cruel actions, he was happy having met these riders who all fought for what they knew was good and heroic for everyone. But now they too are meeting death.

''I met these awesome guys, Riders who fight for each other, who help each other, who fight for the right thing and they're dying too!'' Ryuki yells out even more frustrating, hating this. He hates this; he truly despises the pointless dying. They should be stopping the real villain and yet they have no choice but to fight Tsukasa.

Decade looks around him. He knows he has taken 3 lives but what are 3 lives to billions. It's all the same like the laws of the jungle.

''That's life. That's survival of the fittest.'' Decade tells him as Ryuki startles. He wasn't wrong about that but how he said it, he knew Ren would have said the same thing.

''Ren-san would think so too.'' Ryuki agrees but it doesn't change what he feels. He looks up at Decade and declares, wanting to fight for his reasons too. ''But… I want to protect what truly matters!''

Decade scoffs at this and calls him off, demanding him to fight. ''Then fight me with your all, Ryuki! Fight for the weak and best me!''

Ryuki looks at him and nods, pulling out a card from the Advent deck box, inserting it into his Dragvisor.

''STRIKE VENT!'' The Dragvisor announces as Ryuki gains the Dragclaw gauntlet. He comes at Decade with strong punches which Decade evades with the greatest of ease, kicking him backwards. Ryuki holds his ground as he takes aim with the gauntlet and it fires powerful fireballs.

Decade dodges around the fireballs as Ryuki pulls and slides another card into his Dragvisor.

''SWORD VENT!'' The Dragvisor declares as Ryuki raises his left hand and descends from the sky is the Dragsaber which he catches. Ryuki, hesitating, comes charging at Decade with strong swings and thrusts his gauntlet arm in combination. Decade easily evades the attacks as he switches his Ride Booker into gun form and tosses a card into his belt.

''ATTACK RIDE! BLAST!'' The Decadriver announces as Decade punches Ryuki and immediately fires direct damage across Ryuki's chest, pushing him backwards rolling on the ground.

Decade twirls his gun looking at Ryuki standing up, panting heavily. He didn't expect Decade to be this strong but he can't give up.

''I don't want any more destruction. I don't want the riders to fight any more like this.'' Ryuki expresses as he stands right back up. He can't give up as he pulls out a card and looks at it.

''Ren-san…'' Ryuki says staring at the card and he knows he can't give up, wanting to show his friend that Riders no longer need to fight anymore. ''I'll show you that there must be another way!''

Decade watches as Ryuki loads the card into his Dragvisor, declaring. ''SURVIVE!''

Ryuki erupts in flames at first before he emerges transformed into his Survive form with the Dragvisor transformed into the gun-like weapon, Dragvisorzwei.

Decade scoffs changing the Ride Book to sword form. Ryuki quickly pulls out a card and slides it into the blaster, opening its mouth card loader.

''SWORD VENT!'' The Dragvisorzwei declares as it changes into the Dragblade. Ryuki charges back as the two clash blades once more, sparks flying out as Decade was still superior but does notice Ryuki was striking harder than him. Ryuki swings as Decade blocks and uses this chance to kick Decade hard enough to push him back.

Panting a bit brushing off the hit, Decade pulls out a card and slides it in just as Ryuki times it and does the same.

''ATTACK RIDE! ILLUSION!'' The Decadriver announces as the Dragvisorzwei did the same. ''STRANGE VENT!''

As Decade gains 4 copies of himself, Ryuki Survive suddenly uses the Illusion Attack Ride card's powers, multiplying himself into 4 more. This obvious surprises Decade, uttering out. ''What?''

The 5 Ryuki charge as the 5 Decades clash with them. Natsumi watches looking at that battle basically confused who was who but it began to show as the Ryuki copies easily slash down the Decade copies with their greater strength.

Decade stares at Ryuki and his 4 copies as they aim with the Dragvisorzwei in its gun form and fires powerful beams, nearly blasting through Decade if he didn't jump away. Decade quickly pulls out a card and dunks it into the Decadriver, pushing its handles.

''KAMEN RIDE! RYUKI!'' The Decadriver proclaims as Decade becomes Ryuki and then he tosses another card in.

''ATTACK RIDE! ADVENT!'' The Decadriver announces as a Dragreder appears before Decade-Ryuki as the monster comes at Ryuki. The massive dragon twirls and whips each Ryuki with its fiery tail, destroying the copies but the real Ryuki tanks it though he breathes heavily.

Dragreder roars once more coming at Ryuki Survive until Ryuki's Dragreder, transformed into the more evolved Dragranzer intercepts Decade's Dragreder. The two dragons look at each other and roar, charging at the other. They clash wrapping around each other as they grind their bodies and clash with their claws. The fake Dragreder breathes its flames but Dragranzer tanks the flames and breathes its own flames, destroying the fake one.

Ryuki breathes relax as he thanks his Mirror Monster. ''Thank you!''

Dragranzer roars in response as Dragonic smirks, understanding that thank you. The dragon now gazes upon Decade-Ryuki, roaring angrily as it breathes a powerful fireball. Decade responds fast, tossing a card into his belt.

''ATTACK RIDE! GUARD VENT!'' The Decadriver announces as Decade guards with his arms as the Dragshield shields manifest and he barely blocks the attack. Dragranzer charges at Decade-Ryuki and bites down on him guarding with the shields, shattering them as Decade falls backwards hard as he reverts to regular form.

Decade pants deeply, looking up at the dragon and Ryuki Survive. He gets back up, brushing off the damage and has thought long enough to respond to Ryuki's reasons for fighting him.

''Even if there was another way, there isn't. That's reality. We will never get what we really want but we can try and protect what we can.'' Decade begins to speak up to Ryuki's dismay. Decade turns to Natsumi watching him. He already failed his sister, he wasn't planning to fail her too as he proclaims determinedly. ''That's my reason to help Natsumi. And that's why I can't lose to you!''

Diend scoffs at Tsukasa's words but still loads a rider card as he evades Kabuto's attacks. He takes aim with the Diendriver and fires it at Ryuki Survival.

''KAMEN RIDE! RYUKI!'' The Diendriver proclaims as the energy shout becomes a summoned Ryuki who kicks the real one away from Decade.

Decade turns at Diend and scoffs dunking a rider card into his Decadriver and then taps the fake Ryuki's back as he begins to transform.

''FINAL FORM RIDE! RYUKI DRAGREDER!'' The Decadriver announces as the summoned Ryuki transforms into Dragreder, the massive Mirror Monster red dragon roaring loudly.

''Let's end this.'' Decade declares as Ryuki Survive eyes him and nods, pulling out and sliding his own card into his gun.

''FINAL VENT!'' The Dragvisorzwei announces as Dragreder Survival descends and transforms into a motorcycle that Ryuki Survive lands on and drives on towards Decade.

Decade scoffs as he tosses his card into his belt's card inserter, pushing its handles.

''FINAL ATTACK RIDE! RYUKI!'' The Decadriver announces as Decade leaps upward as Dragreder flies around Decade. Ryuki Survive continues driving towards him and performs a wheelie, followed by Dragranzer shooting several fireballs at the descending Decade.

Dragreder blocks the fireballs as best as it could as Decade comes down at Ryuki with a Rider Kick as the dragon breathes intense flames behind him, consuming him as it launches him downward. Ryuki tries countering, leaping his bike upward and slamming him with Dragranzer. The two clash but Decade's kick cuts through both Ryuki Survive and the Dragranzer.

''You're strong… Tsukasa-san…'' Ryuki begins to express, suddenly coughing blood through his mask. He tries to chuckle happily but in reality he feels like a failure, unable to stop all of this and be friends with all of these heroic Riders.

Trying to reach out to him, Ryuki asks him weakly. ''Promise me… to save those who can't fight… and those who don't deserve to die.''

Decade stares at him as cracks start to show on both Ryuki and Dragranzer.

''I… I don't want to have any regrets…'' Ryuki utters his last words as Dragranzer shines and explodes. Ryuki is consumed and destroyed along with his dragon. Decade looks at the flames of what Ryuki was and just nods, not going to let his death be in vain.

''… I will.'' Decade simply responds turning around and awaits him is Den-O, approaching the rider as he had kicked Absol away.

''Geez. I guess I better be the one to put you down in your place, asshole passing-through guy.'' Den-O proclaims tapping the back end of his sword over his shoulder. Decade just chuckles at this and responds pointing at him. ''You sound sure about it, Momotaros?''

This staggers the rider. Den-O clenches his fist, both the Imagin and the human feeling conflicted to kill Decade but they'll do what they can.

''I'm coming at you, Decade.'' Both Momotaros and Ryotaro both respond in synch as Den-O proudly takes on his signature battle pose, shouting out loudly. ''Ore Sanjou!''

Decade scoffs as he wipes his hands and comes at him. Den-O comes at him, swinging right away but Decade dodges around his sword swings and then delivers a punch followed by a kick, stomping Den-O back. He scoffs brushes off the damage coming at him again but Decade aims with the Ride Booker, dunking a card into his belt.

''ATTACK RIDE! BLAST!'' The Decadriver announces as Decade fires multiple power barrages at Den-O who tries repelling the shots but they eventually hit him and blast him backwards hard. Decade scoffs twirling his gun as Den-O gets up coughing.

''You forget.'' Den-O begins to say as he pulls out the red cellphone K-Taros. He flips the phone and dials the code 3-6-9 before attaching the cellphone over the Den-O belt.

''There's more than one Den-O! Let's start our Climax!'' Den-O declares pressing the silver button on the side and the phone glows. ''CLIMAX FORM!''

Rails start wrapping around Den-O as the other Taros' head pieces attach themselves on some parts of his body, transforming into Den-O Climax.

Decade scoffs as he pulls out a card and taps on it twice.

''I like the sound of that.'' Decade declares sliding the card into his belt's card inserter and pushes its levers forward.

''SUPER FORM RIDE! DEN-O CLIMAX!'' The Decadriver announces as Decade wipes his hands together as he too becomes Den-O Climax Form. Den-O scoffs, not worrying as Decade tosses another card into his belt.

''ATTACK RIDE! ILLUSION!'' The Decadriver then proclaims as Decade multiple each one having become a different form of Den-O: Sword, Rod, Ax and Gun forms. This startles Den-O and the Imagins watching this.

''Ah come on!'' Den-O complains upset as all the Decades come at him with Gun form shooting a distance. The shots stun Den-O as Rod strikes his chest followed but Sword and Ax jumping off his shoulders and slashing Den-O across the sides of the chest. Sparks fly out as the main Decade-Den-O slams a powerful drilling rainbow colored like punch upon the real Den-O, smashing him backwards.

Den-O grunts heavily not expecting this kind of beating but he isn't bested as he pulls out the Rider Pass and swipes it over his belt.

''CHARGE AND UP!'' The Den-O Belt announces as Den-O tosses away the Rider Pass and as Den-O points and he fires the blade part of the DenGasher, firing through one of the copies and destroys it. Den-O begins moving the sword as the blades follow his movement, slashing down more of the illusions with quick strikes.

Raising his sword, Den-O shouts passionately. ''Our Finishing Move, Climax Version!''

The blade comes down and seemingly hits Decade… but the blade is caught between the fangs of Absol. Den-O staggers heavily. ''WHAT?!''

Absol grins using Detect to catch the blade.

''Good job mutt.'' Decade praises her as he slides a card into his belt and comes charging forward.

''FINAL ATTACK RIDE! DEN-O!'' The Decadriver announces as Decade-Den-O leaps forward and manifests a powerful kick with the DenKamens moving to his right leg, releasing a rainbow aura-like burst of energy.

Den-O panics as Decade's Rider Kick breaks kicks upon Den-O, causing a powerful explosion that sends Den-O flying backwards.

''GAAAH!'' Den-O yells out as Momotaros and the other Taros fly out of the main body and only Ryotaro is still transformed but in the Plat form.

Decade breathes as he reverts to his regular form and taunts the rider. ''Even if you use the power of all the Imagins, you won't beat me.''

''… I know… but…'' Responding, Ryotaro speaks standing back up as he looks at the other Taros. He wouldn't have become the person he is now without them. To him, they were family and irreplaceable comrades. He can't let them down.

''I made a promise to myself, to the Taros, to never let my fear and doubts cloud who I can be.'' Ryotaro, Den-O, proudly speaks up loudly to not give up on his comrades. He grips on the K-Taros and presses on the Den-O button as he reaches out with his right arm. The other Taros watch and feel the same with Momotaros leading them, becoming energy that shoots towards him.

Decade watches as Den-O reaches out as the energies of the Taros merge within his hand, becoming the DenKamen Sword.

''I won't fail them!'' Ryotaro vows as he slides the Rider Pass in the back slot of the blade as it shines.

''LINER FORM!'' The Den-O belt announces as the Plat form erupts in aura and becomes Den-O Liner Form.

Decade stares at this and declares. ''So that's your resolve…''

Den-O Liner Form comes at Decade with insane speed until Decade dunks a card into his belt.

''ATTACK RIDE! INVISIBLE!'' The Decadriver announces as Decade turns invisible and causes Liner Form to hesitate where he was. Instead he focuses and feels something. Liner Form turns and swings, sparks flying as it hits an invisible Decade with ease. Decade rolls, coughing as he gets up. He could feel his resolve and he won't deny it.

''Then…'' Decade begins to say as the Diendriver announces. ''KAMEN RIDER! DEN-O!''

Den-O quickly moves away just evading a sword swing of the summoned Den-O Sword Form, mimicking the real Momotaros by holding his sword by the shoulder. Decade walks up on his back and eyes a card he pulled out from the Ride Booker. He looks at it before finally dunking it into the Decadriver and then taps the fake's back. That Den-O begins to glow and transform, flying upward.

''FINAL FORM RIDE! DEN-O! DENLINER!'' The Decadriver announces as it transforms the summoned Den-O into the DenLiner which shocks Natsumi having been told by the Final Form of Den-O by Dragonic.

''DenLiner? Not Momotaros?'' Natsumi questions as Dragonic answers firmly. ''Seems Tsukasa wants to finish this with full force.''

Liner Form looks at the train circling over Decade as he holds his sword with both hands before pressing a dial on the K-Taros.

''FULL CHARGE!'' The Den-O belt responds as a burst of red-blue-yellow, purple and white aura of energy surrounds Den-O as rails manifest from the sword towards Decade.

Decade immediately slides in a Rider card into his belt, pushing its handles. The DenLiner responds as it flies and Decade leaps on top of its front. Den-O soon charges forward and leaps on the rails, grinding on them.

''Train Slash!'' Liner Form shouts swinging forward as the energy mirage of the DenLiner manifests around him. Decade responds by holding his Ride Booker gun form with both hands.

''FINAL ATTACK RIDE! DEN-O!'' The Decadriver announces the fake DenLiner rams right at Liner Form's attack, unloading ad unleashing its weapons and fires a constant blast of energy, missiles and cannon blasts at Den-O. The slash does its best to cut through the assault but it quickly consumes him as the DenLiner rams through the aura form DenLiner and tears through Liner Form. Den-O screams, sent flying upward and crashes onto the ground. His form dissolves his aura starts to glow around the defeated aura.

''Sorry, everyone…'' Ryotaro utters out actually scared and yet Momotaros responds in his sand-like Imagin form, chuckling. ''Heh, don't feel bad, Ryotaro. You did your best.''

Ryotaro didn't show but he did shed a tear. He looks at the other remaining riders, wishing them the luck he didn't have. ''I guess the rest are up to you…''

And soon the aura goes crazy and explodes, consuming and destroying Den-O. The fake DenLiner soon vanishes.

Natsumi frowns really depressed, having witnessed 5 riders, 5 good people die for nothing. Dragonic didn't say a word.

Absol stares at Decade who is now gazing towards the last 4 riders: Blade, Kiva, Kabuto… and Kuuga.

''The Four Heavenly Kings…'' Decade says to himself trying to make a taunt out of it but couldn't. He just clenches his right fist, not planning to lose to them declaring. ''Let's settle this!''

Author's Note: Time to clarify things:

1) The climax is a sort of World of Merging but having it all happen within the World of Decade. Plus a final nice moment with our group, all together.

2) A twist of the Rider War as each main protagonist rider is themselves but having made up their mind that the only way to stop the merging and destruction of their worlds is to defeat and destroy Decade. Thus the battle between Decade's team versus the other Riders began. Plus in this one the stakes are huge and the moment Tsukasa and Natsumi had, promising her to change the dream which she revealed.

3) Yes, one-on-one since well it would be much harder and unlike how Decade dismantled all the Riders with Violent Emotion, Tsukasa uses the powers of those riders and the Final Forms to beat them. Plus a small scene in between.

4) OH yes, all the Riders are using their final forms because that should have happened. No arguing!

I have my reasons that the last 4 riders standing are these 4. Kenzaki to fix what I would imagine a battle between Decade vs Blade King Form would look like, Wataru to start a fight that I wanted to see (and a certain topic I will cover), Tendo to settle their last fight and Yusuke because Ultimate Form. And yes, I know Blade is weaker than Den-O but I am making exceptions.

Next time the Rider War reaches its final climax! Will Tsukasa keep his promise to Natsumi? Will her nightmare change?
