Chapter 11.5: World of Construction and Victory!

The fight between Cross-Z and Diend heats up as the dragon rider tries punching Diend while resisting as much as his shots and attacks and Diend is easily evading his hits all while sliding 4 cards in a row into his Diendriver.

"KAMEN RIDE! G3-X! KNIGHT! IBUKI! ZERONOS!'' The Diendriver announces as he fires 4 shots and they become his summoned Riders. All 4 summoned riders attack Cross-Z who tries fighting all of them at once but he soon finds himself overwhelmed by G3 and Ibuki's long range weapons as well as Knight and Zeronos' close combat weapons. Diend then dashes at a stunned Cross-Z and fires multiple shots across his stomach before the last one slams him into a wall.

Grunting enraged, Cross-Z leaps out of the wall and shouts, already done with this. "Now you're pissing me off!" He grabs the lever of his belt and starts spinning it as the driver starts chanting. "ORA! ORA! ORA! ORA!"

Diend watches this with a snicker, sliding in a Rider Card into his gun and loads it in. ''FINAL ATTACK RIDE!" The Diendriver announces as Diend takes aim.

''READY GO!" The Build Driver announces as Cross-Z jumps forward towards Diend. "DRAGONIC FINISH!" An energy dragon forms behind Cross-Z and fires upon him, blasting him forward instantly right at Diend. However, Selina suddenly gets in front of him to his shock and she purrs, using Sucker Punch by slamming her paw across his head and pushes him away, canceling his attack as he hits the ground and his transformation undone.

Snickering by his partner's help, Diend charges up his gun as his summoned riders become energy and become part of his weapon's charging energy before he fires. "DIEND!'' He fires his signature cyan energy blast at Banjo, about to consume him entirely.

"DRAGONAUN BURST!'' Suddenly a super charged, fiery purple blast that blocks and clashing against Diend's attacks, exploding on impact.

''What the?!'' Diend utters in shock as Dragonic suddenly teleports in front of him and twirls his body, swinging his dragon tail and smacks him so hard it launches him out of the building.

''Mess with a dragon and you mess with me." Dragonic declares with a smirk, crossing his arms. Banjo blinks puzzled before he says thankfully yet nervous. ''T-thanks?''

Meanwhile, Natsumi watches in dread until her expression changes, seeing through the explosion is a green barrier blocking Evol's kick and it is Layla, in her Mega Form as she's using Protect.

''What the?" Evol utters in confusion before Layla barks and times it, dropping her barrier and immediately unleashing Night Slash from her horn across Evol's chest as it sends him flying backwards. She pants heavily, barking so drained that she reverts back to base form. ''Ab… sol."

Panting too, Decade finally gets up on one knee as he pets the Absol, praising her. ''Good job, Layla."

Layla still barks weakly, knowing they're still very much screwed.

Evol stands up, scoffing that some monster dog hit him. Now that justifies killing the stupid- Suddenly he's slashed across the back by Build's Fullbottle Buster, sparks flying out as he turns only to get kick by RabbitRabbit's kick, extending and slammed him across the wall.

"Sento..." Evol utters as the foot pulls back and he laughs, wagging his finger at Build. "Not your turn yet, hero."

"Evolto, I won't let you regain your powers again!" Build declares as he comes at him only to get intercepted by multiple Smashes that Sayo is controlling.

''That's enough, Evol!" He turns his head towards Sayo, having seen enough to be convinced this was worth it as she then orders him. ''Retrieve the box. That way my power will surpass the Great Leader and kill him, ruling Dai-Shocker as the new leader."

Decade looks at her, frowning underneath his mask.

''Right-right…'' Evol begins to say, moving his arms up and down… until he vanishes and reappears right in front of the foolish little girl, looking down at her, and tells her with a firm, cold yet sadistic voice. "Not~''

This stuns Sayo who gets mad at this change of attitude and questions him angrily. ''You dare. Must I remind you of disobeying me!" She snaps her fingers, releasing the inner dark energy she placed in his body to tear him apart… but nothing happened.

Even Evol hums, checking his body and arms before he begins to say, shrugging his shoulders. ''Strange huh? I should be feeling an overwhelming pain…'' He ponders before he cackles and corrects her with an ominous voice. "And I'm feeling none of that thanks to Cobra Evol."

This shocks her, not expecting this form of his would resist her power. She tries to control the Smashes to attack Evolto but he simply waves his hand and they all stop under his command.

"This is what happens when a child thinks she's under control." Evolto begins to proclaim before his eyes glow evilly. "They never are."

Immediately, Tsukikage transforms into Shadow Moon and swings his Satansaber at him only for Evol to vanish in the last second and reappear away from them.

"But I will gladly follow your plan except I will be the one to rule and devour all worlds!'' Evol proclaims proudly before he turns into red sparkling gas and flies right to the transformed Banjo. The other Sento watches this too late as the gas enters within his body.

"BANJO!" He yells out with the main Build seeing this and muttering of concern. "Not again."

"…" Slowly forming a smirk as he stands up as his eyes glow red, Banjo pulls off and tosses the Build Driver with the Dragon Fullbottle. Selina quickly catches them and dashes away. As that happens, Banjo suddenly straps on the Evol Driver as a new bottle forms in his hand. He shakes it and another in his hand before sliding them into the driver.

''DRAGON! RIDER SYSTEM!" The Evol Driver announces as he twirls the lever. Soon the same gears form around him as he crosses his arms and speaks, but Banjo's voice is not his but Evol's. ''Henshin."

He spreads his arms forward as the gears become a sphere and spin around him rapidly as the driver announces. "DRAGON! DRAGON! DRAGON EVOL!" Soon the gears shatter and he's transformed into Evol Cobra except the visor is more like Cross-Z.

"Even if this isn't my Banjo, guess it still works!" Evol expresses with such humorous joy. Sento sees this and gets mad, not expecting Evol could do that with the other Banjo. Must be whatever they did to him to give him these new buffs to his powers.

Flexing his wrists, Evol needs more time to fully recover his energy. Plus, it'll only torment both Sentos.

''I'll see you all very soon. Caio!'' Turning to the group, Evol bids farewell with his signature hand gesture before he dashes away as a blue blur. All the transformed Smashes also vanished too.

The group is left there with Decade scoffing, turning his sight towards Sayo and Shadow Moon both gone. Decade grunts as Diend walks out from the hole he was blown out of, brushing off the damage and honestly not expecting this twist.


An hour passes as the Pandora Box is moved to a protective fault that only the other Sento has access to but it wouldn't matter. Actual Sento states that Evol will fight his way through the vault to reach the box and achieve his true potential. Time is running out for them.

''We have to save Banjo!" A.R Sento expresses, already feeling bad for Kazumi and Gentoku currently unconscious and thinking of the Professor- thinking that Evolto cared for him.

"He's going after the box. We'll wait when he arrives.'' Sento proclaims calmly, his arms crossed. This upsets the other him who yells at him mad. "How do you know?! He has my friend and you think he's still coming back?!"

"… Experience." Sento simply responds, knowing Evolto better than anyone. He stands straight, staring at his other self and questions him. "Complaining won't help anyone. You're a Kamen Rider, aren't you not?"

"…" The other Sento is silent, looking away as he utters nervously. "I-I don't think I can be." He frowns, recalling his denial to many and proclaims. "I-I am not like Tsukasa-san or Banjo. I just want to use my science to help others.''

"…" Silent as he used to think being a hero wasn't for a man who couldn't even remember his own past, Sento also remembers how science both helped and almost destroyed humanity; Evolto being a prime example for his benefit and evolution, but also Build to help others.

''Science never helped anyone. It leads to creating new ways to kill people." Sento begins to say, remembering his words all too well but then he counters that statement with his own belief. "It's how we use that science that makes a different path, a new possible hopeful future."

Tsukasa oddly smirks, for once impressed by the so-called hero of justice. He steps up as he tells A.R Sento. "Not doing anything while blaming yourself for trusting or helping Evolto won't save your friend or your world either."

He walks up to his assistant and encourages him firmly. "You want to save him? You use your science to stop Evolto. You want to be acknowledged then first acknowledge yourself."

A.R Sento's eyes widened in shock as Tsukasa further says calmly as he removes his lab coat, remembering his sister. "You'll never escape the sense of failure. All you can do is push yourself up and find the hope to keep on fighting. That is what a scientist is. That is what a Kamen Rider.'' He eyes the other Sento and quotes him. "That is what a hero does it."

Sento actually smirks at that, misunderstanding this guy. God, he hopes his Banjo never learns he mistook this guy with Dark Decade.

"Tsukasa-san." A.R. Sento utters, closing his eyes for a moment. He's right. Being acknowledged by another got him into this problem and now Banjo is in trouble. He has to save his dear friend and to do so; he has to believe in who he is.

He opens up his eyes, looking at Tsukasa and nods. Tsukasa smirks, trusting in him to be a hero too. He walks away as the two Sentos have a discussion that the A.R one might have a way to stop Evolto.

As they talk, Tsukasa walks up to Daiki who hasn't left. He stared at Banjo's driver before putting it away, finally this world's treasure and yet it felt… too easy. He likes easy quests but he also felt "ripped off" in a way. His eyes look up at Tsukasa, right in front of him with a look of disgust that he's even bothering to ask for his help but against Evolto; he might need some help.

"Kaito… I'd like your help." Tsukasa asks him to Natsumi and Layla's shock. That's really rare for Tsukasa to ask for help, nonetheless his least favorite person.

Actually grinning by the out-of-character request, Daiki questions him almost uncaringly. "And why should I, Tsukasa-san?"

Smirking as he knows how he functions, Tsukasa proclaims. "Because I know you'll prefer a better treasure; Evol's driver."

This gets to Daiki, eyes widened like a look of excitement. The Evol Driver is a rare and wonderful treasure, one suited to a Treasure Hunter such as himself.

"Am I wrong?" Tsukasa questions him with a smirk.

"..." Silent for once, Daiki is debating about passing down such a good hunt… but he can't do it. After all, with the princess of Dai-Shocker involved, no doubt the Great Leader might appear. He made an exception last time in the A.R World of Ghost just because it was to save Natsumi and nothing else.

"… He's going to be targeted by Dai-Shocker. It's not worth the hassle." Daiki, out-of-character, turned down the idea. Selina frowns to hear that and so does Tsukasa, figuring as much as he then mocks him. "Not worth it or too afraid to commit?"

That last line got to Daiki, gazing up at him and uttering with a firm voice. "What did you say?"

Taking a step forward and bending right to his face, Tsukasa looks right at his eyes and tells him off with the truth. "… You're afraid, Kaito."

An awkward silence looms around the two while Natsumi gulps, thinking Tsukasa might have crossed the line. She knows Daiki too but… to be honest, he has been a bit off since Dai-Shocker appeared.

"Me? Afraid! Hahaha!" Breaking the silence with a small chuckle, Daiki begins to express with a small smirk. "You're funny, Tsukasa-san."

"…'' Tsukasa looks at him, still quiet and more so with a stern face before making a big puffy cheek face with his arms crossed. This causes Daiki to slowly stop laughing, finding this silence troubling.

"You keep saying you're a treasure hunter and yet you're a thief…" Getting serious, Tsukasa begins to finally speak about Daiki as a ''person'' but past his many-many flaws; he knows he has no one that fears him, until now as he points his finger at him. "But you're a thief who isn't afraid of who he screws over, except Dai-Shocker."

Daiki slowly makes a glare with Selina gulping. Natsumi blinks with Layla and Dragonic nodding, suspecting as much. Tsukasa has noticed it. He would go after his target as fast as possible and do all he can to snatch his "treasure" before Dai-Shocker reveals themselves or while they're distracted with him than getting in Tsukasa's way like usual. With the exception of Natsumi in the A.R. World of Ghost; Kaito never bother staying long in a world that Dai-Shocker had their eyes on.

"You've been distancing yourself, especially when Dai-Shocker gets involved. Why?" He asks Daiki with his arms crossed. No response. Tsukasa sighs as he makes an assumption. ''It's likely because you're scared of Dark Decade or of someone else too."

Again, no response as Daiki clenches his hands.

"The Kaito I know wouldn't hesitate who he crosses; he'll take what he wants especially with me." Tsukasa then declares, knowing the kind of man he is and what he's doing is not his character. "Answer-''

"SHUT UP!" Losing his temper, Daiki actually yells at his own rival with a tone of fury. That response surprises everyone but not Tsukasa, Dragonic or Sougo, seeing through his fear.

Breathing heavily, Daiki then says with an angry voice. "You don't get to lecture me! You're no different when it involves your parallel sister!" That gets under Tsukasa's skin.

"And you don't give a damn if I lecture you or not!" Tsukasa replies back harshly, disagreeing with him. Daiki groans, turning his back to him and just mutters. ''I have no reason to help you but I'll only do it to get rid of that psychopath. Then I'm gone.'' He soon walks away, furious with Selina purring to them and chases right after her partner.

Tsukasa lets out a sigh, not a fan of the stubborn Kaito… But this causes him to think of the other Sayo. He can't be a hypocrite if he doesn't face his own fears too.

He begins to walk away to Natsumi's alarm as she calls out to him. "Tsukasa-san?"

Stopping, he turns around and tells her with a smile. "I have to do something before we fight Evolto." He eyes Dragonic and asks for his help. ''Dragonic, help me out.''

''You bet!'' The purple dragon answers with a small smirk. Tsukasa nods as he prepares to go until A.R Sento yells out to him as he and the main Sento are working on something. "Tsukasa-san, come back soon! I'll have something ready to stop him!"

Tsukasa smirks at his change of attitude, telling him in a taunt. "You're a naïve guy. Don't lose that attitude." He turns around with a glare, imagining how his other version of his sister feels towards his evil self. "Anyone would be tricked by monsters."

He and Dragonic head out as Tsukasa has a sin he must repay and fix.

As he leaves, Kiva-la coos as Doctor Shinigami is watching from the shadows, snickering as he looks down at Natsumi. He prepares his plans until Natsumi and Layla suddenly run after Tsukasa, wanting to be there for him. He just scoffs but is still humorous; going to have to wait a little longer.


Away from the building, Sayo looks up at the dark, starry sky. It's a beautiful sight, seeing so many stars. She recalls how she and her brother would look up at the sky like this, making wishes. She wished that they would travel the whole world together… but her brother wished to be king. How ironic that wish came true and so did hers but without him.

"… Nii-san, no, the Great Leader will kill us.'' She begins to say, imagining how enraged he'll be once Evolto reaches his final form and starts invading other worlds to devour. No doubt the Great Leader will kill him and then he'll kill her and Tsukikage to even try to betray him.

"I thought I could control Evolto. Why? Why couldn't I control him?'' She questions as she places her hands over her face, having done this to so many and yet she fell hard. Tsukikage frowns saddened, not seeing her so dismay but he doesn't know what he can tell her to-

"Because you overestimated yourself." Sayo removes her hands off her face, eyes widened as she turns around. Tsukikage also turns around angrily as Tsukasa approaches them with Dragonic hovering next to him. Natsumi and Layla watch them from behind.

Overhearing what she said, Tsukasa finally understands why Sayo wants to rule Dai-Shocker and much like Daiki: It's fear.

"I get the gist now, Sayo. The other me, Dark Decade, intends to get rid of you. Isn't he?" He asks her calmly to her dismay. ''And you want to secure your protection by taking control of Dai-Shocker."

Sayo frowns, gritting her teeth softly. He's just as quick to read her like her brother. Then, did he always-

"It was a brilliant plan.'' Tsukasa begins to admit, having this world devouring villain under her control to somehow overpowered Dark Decade except it seems they were all tricked by how smart that same villain is. ''Would have worked if not for how clever and backstabber that Evolto is. I can't blame you."

Sayo is silent, admitting that he's right. She did overestimate Evolto. She pulled him out of his time, weakened and easy to use like a puppet and instead he's been playing with her from the start. He-

"YOU DO NOT GET TO SPEAK TO HER LIKE THAT!" However, Tsukikage is not the same as he lashes out so much that he charges at Tsukasa while he transforms into Shadow Moon. He swings his sword at him only to get blocked by Dragonic's claws, swiping and repelling him back.

"Stop it, Shadow Moon!" Sayo orders him in awe but Shadow Moon refuses, having lost her once already in his world and it will not happen again.

"You already took my mistress from my life. I will not let you do it again!" Shadow Moon declares, filled with nothing but hate and his loyalty for his princess even when she protests. He raises his blade and declares furiously. "I will now kill you and silence you forever, Tsukasa Kadoya!''

Sighing at this, Tsukasa walks in front of Dragonic, already wearing his Decadriver. He holds up a Rider Card and slides it in slowly as he pushes the levers of the belt forward.

''KAMEN RIDE! DECADE!" The Decadriver announces as Tsukasa still walks forward, transforming into Decade as his visor eyes glow green.

Growling, Shadow Moon charges again with another sword swing but Decade easily dodges it by side-stepping the attack to his surprise.

"Tsukikage, your hatred towards me is your failure in protecting Sayo." Decade begins to tell him right next to him of their Sayo's passing. "It wasn't your fault but instead of moving on, you put the blame on me and even yourself."

Becoming madder, Shadow Moon comes swinging faster and more irrational, easy for Decade to side-step around each one of his obvious, wild swings.

"You succumbed so low you became the A.R Shadow Moon, a monster far worse than the original." Decade proclaims, almost mocking his decision in becoming what he is now and that only enrages Shadow Moon even more.

''SHUT UP! YOU CAUSE ALL OF THIS!" He yells furiously, swinging this time so strong it releases a red energy slash that Decade blocks with his forearms and pushes it back.

Shadow Moon growls as Decade wipes his hands together, proclaiming his outburst. ''Maybe I did, but I'm not a petty fool.'' He pulls out a Rider Card, tapping it twice before sliding it into the Decadriver.

''KAMEN RIDE!'' The Decadriver announces as Decade pushes the levers forward and transforms into… ''BLACK!''

Becoming madder that he chose to use that form, Shadow Moon charges with a stronger sword swing. This time, however, Decade-Black catches the Satansaber by the blade with both hands, sparks flying out from his palms but locking the blade in place.

This shocks Shadow Moon as Decade-Black kicks him across his right rib so strong that it launches him backwards while multiple sparks fly out across his stomach. Shadow Moon nearly gags up, grinding his feet on the ground as he nearly stumbles over. He looks up at Decade, squeezing the grip of his sword as he shakes it; not able to forgive him.

''Damn you! DAMN YOU, TSUKASA!'' Shadow Moon yells out as he comes charging at him. Decade-Black doesn't bother to respond as he thrusts a Rider Card into his belt.

"FINAL ATTACK RIDE!" The Decadriver announces as he leaps forward and performs Black's Rider Kick, kicking right at Shadow Moon across the chest. "BLACK!" The kick strikes Shadow Moon and sends flying away into the forest.

Sayo watches in shock, staring at Decade-Black who reverts back to base form and turns to face her. He begins to approach her, causing her to have a panic attack as she backs away. She tries to get away but he moves so quickly that he's already in front of her. Sayo has an expression of dread, thinking he'll end her like her brother. In the end, they're both-

Suddenly Decade's body glows and she widens her eyes as she finds herself being hugged by the untransformed Tsukasa.

''…'' Sayo is gawky silent by this; an affection she's never received in a long-long-long time not since her parents died… and when her brother did care for her.

"There-there. It's not your fault.'' Tsukasa tells her, patting her head gently. Sayo just blushes softly, not sure how to feel but it's not fear or horror… and it terrifies her.

"W-why?" She begins uttering out, able to push him off her. She stares at him firmly as she questions him, madly. "I'm your enemy! I want you dead! Why… WHY THE HELL DO YOU-''

"Because you're my little sister." Her words are cut off by Tsukasa's bold response. She flinches but soon she interrupts coldly. ''Don't think you can use me as a replacement to-''

Immediately, Tsukasa shakes his head as he tells her with a saddened smile. "My Sayo died, happy. But you're also your own Sayo with your own hopes and dreams and even if you come from another universe…'' He reaches out and rubs the top of her head. "You're also my little sister. And nothing will change that."

Sayo is just silent by his words, nothing that her brother has ever told her.

"… You and him are both so alike and yet so different." She realizes her mistake about him. She can't even smile, still thinking of her brother as she tells him. "He… he wanted to conquer the worlds he saw because it gave him purpose in life.''

She frowns more, thinking of all the Great Leader's dark desires and goals, going as far as to kill any who will oppose or even ruin the world he wants… and yet he loves the idea of slaughtering and destroying.

"Everything to him is boring without conflict. To conquer worlds, to kill his enemies, that is his thrill, his life." Sayo then reveals with a grim expression. She could never tell such a thing to him because of how he kills any who speaks down to him.

"I see." Tsukasa mutters, confirming his suspicions as to why she's afraid of him.

Sayo frowns, recalling how she would obey him faithfully and yet he only looks down at her like she's an ant.

"I thought if I followed him, it would make him happy. He's the only family I have." She proclaims, feeling like a failure that nothing changed as she looks back at Tsukasa who's looking at her. "And yet he never batters a look towards me of affection unlike you. All he sees is what he wants to conquer next.''

She looks at him and asks him about who he is compared to the Conqueror of Worlds. "Is that why you're a Destroyer? Because of the conflict of the Riders or the death of your- of the other me."

"…" Silent, Tsukasa thinks back on the day he became Decade and the only reason he did was when she asked for his help. Smiling, he looks at Sayo and proclaims as he looks behind him to stare at Natsumi. "I became a Destroyer for Natsumikan. I wanted to save her and protect her world. Then I want to protect the worlds I saw and will see, even if I must destroy them to bring them back."

Natsumi blushes red, smiling as she's never regretted on that day to give Tsukasa the Decadriver. That response astonishes Sayo, realizing why the Great Leader finds him as a worthy challenge.

"I see why he views you with so much interest." She says to Tsukasa's amusement as he also admits. "I do too about him and try to figure out why he's the way he is."

Sayo also agrees, questioning what happened to make her brother like that.

"I just…" She begins to mutter sadly at her powerless state since she couldn't do anything for her brother. "I don't know what to do."

Tsukasa breathes, looking up at the sky. He stares at the calm skies, recalling the last time he and his Sayo saw that sky before her sickness got worse. He smiles, remembering her smile when she expresses how she'll be able to capture the image of the whole sky.

"You see and capture the world with pictures." Tsukasa begins to say to the young teenager who blinks in surprise. He eyes her with a smile, further saying. "That's what my Sayo wanted to do: Explore the worlds and secure their memories through photos."

Sayo is quiet, recalling when she was little that she used to feel the same, not a lot like the other version of her but the mere idea to escape her troubles… It does feel right.

''I-I would like that." She admits with Tsukasa smiling. "I would too."

The two stare at the other just as Shadow Moon suddenly appears again, badly damaged.

"M-Milady…" He tries calling out to her, not going to let the destroyer brainwash her with lies. He can't fail her, not again!

Sayo turns to eye him and frowns, saddened. "Tsukikage…" She took advantage of his loss, of his anger, of his despair to turn him into Shadow Moon with her power and it was a mistake. She can't control him any longer just like how she wanted it for her brother.

Walking up to him, looking at his defeated pose; Sayo still frowns as she apologizes. "Sorry. I can no longer be with you. I used you and… I'm sorry."

Shadow Moon doesn't care, gladly giving himself up for her. Sayo still frowns, knowing what she's done is still wrong and she requests him. "Pursuit your own happiness. That is my only wish to you."

He still tries to reach her, too weak and yet he doesn't want to lose her again. However, he ultimately falls unconscious.

Sighing, she turns back to Tsukasa and says. "Thank you, Decade…" She then smiles and corrects herself. "No… Thank you, Nii-san."

He nods, wanting her to just be happy. Sayo bows as she walks away but towards Natsumi. She walks past her and pleads to her. "Keep him safe. He'll always need you."

Natsumi just blushes but nods, always going to be there for him. Sayo just smirks as she walks away.

Dragonic eyes Tsukasa, able to tell he feels… Closure. He smiles, glad he could save one Sayo. He wishes... that he got the same chance to with his princess. He wishes he could have saved her and Sir-

"Tsukasa-kun!" Dragonic snaps out as Tsukasa turns to Natsumi, running over with Layla beside her. Smirking, he proclaims as he still has the villain to fight. "Time to face a Frieza.''

''I was going to say Galactus or Thanos.'' Natsumi suggests. Tsukasa gives her a look before he smiles and declares, making this funny. ''Let's face the Anti-Monitor then.''

Dragonic oddly grins with Natsumi smiling as the group heads out with Sayo watching them from afar, so very confused. She realized that maybe her brother needed friends like that. Maybe… she can too as she walks away, going to reset her life.


After an hour later, Evolto finally attacks again, strolling his way through an army of guards. This was more than a simple task all while humming. He even sent the Smashes as a distraction since he knows the only one who can stop them and revert them back to normal humans is Sento. And he knows he's stopping them and by the time he arrives to face him; nothing will stop him.

Evolto easily trashes through the transformed "rider" armored guards, easily bashing them aside as if they were flies. This was almost too easy, feeling the Pandora Box so much closer to his possession as he reaches out to the vault-

"Hey, body snatcher!'' Stopping inches from the door, Evol Dragon turns his head 90° degrees to the left and there; Tsukasa is waiting for him. He's eating a container of Pocky with Dragonic, both waiting for him. Natsumi and Layla are standing outside, mainly because they don't want to face him.

Evol just looks at them with his head lean to the right, questioning how long they have been waiting for him here. Putting away the box, Tsukasa stands up as he has his Decadriver already around his waist.

"I'm not letting you take a single step forward." He declares, pointing his finger at him. Evolto can't help but snicker a bit, taunting him unconcerned. "And you think you can hurt me with this fool in my possession?"

Tsukasa hums with a small smirk across his face.

''You make a good point…'' He begins to agree with him but then he responds cockily. "That's why I have friends."

Evol leans his head to the left, not following what he's-

"FINAL ATTACK RIDE!'' The voice of the Diendriver announces as a shine glows from behind Evol, startling him as he turns around to see Diend firing a powerful shot at him. "DIEND!"

Just barely reacting as the Cyan energy blast hits him, Evol vanishes into blue sparkling energy, evading the blast and reappearing right behind Tsukasa.

"Oh?! You think such a simple trick could-'' He begins to mock the human's feeble, little last shot to beat him… until he sees Tsukasa's smug smirk as he turns slightly towards Evol.

"It's called a distraction.'' He taunts the dark rider. Evolto leans his head confused and immediately panics, turning and staring eye-to-eye to Dragonic, floating right behind him. Smirking, the dragon roars, thrusting his claw right into him. "FORCED SPIRIT FISSION!'' His claw hits Evol Dragon across his chest, actually cracking the chest armor. It stuns Evol as the dragon releases a purple energy wave. It hits across Evolto, causing him not physical pain but his cells and being pulled out of Banjo and blasting him away, now turned back into Evol Cobra.

Grunting, Evol looks at himself and his Evolbottles, uttering in dismay and agony. "WHAT THE?!"

Dragonic smirks as Banjo hits the ground, freed, as the Dragon Evolbottle hits the ground.

"Nyan!'' Tsukasa turns and spots the Purrloin suddenly grabbing that bottle and snatches it to Diend who accepts it happily.

"Good job, Selina." Diend praises her quick thieving as he turns towards Tsukasa and tells him with an arm bow. "Leaving the rest to you, Tsukasa-san.'' He summons an Aurora Curtain and it sucks the two inside of it, vanishing.

Grunting in confusion as he looks at him, Evol utters in confusion. "W-what the hell did you-''

''I split you from Banjo." Dragonic explains it as simply as possible, smirking with his arms crossed. "Pretty cool, no?"

''Now your plan has been foiled. You-'' Tsukasa begins to proclaim confidently of his defeat… only for Evol to begin laughing loudly and evilly, smacking his right hand on the ground as he stands up. ''HAHAHAHA! It's almost funny that you think I needed him!"

This confuses Tsukasa and Dragonic as Evol reveals his trump card. "Using that fool was meant to break the other Sento's spirits, to see you all fall and at the end of the day, I will show you that dread…'' As he pulls out the malicious Evol Trigger that he always had as his visor eyes glow with a voice of dark humor and cruelty with a dark outline of energy forming around him. "That perfect despair~!''

Dragonic widens his eyes, literally having a panic attack as he sees the image of the demonic mothman entity, looking back and its demonic eyes staring back, almost making an expression of humor and mockery.

''Stop him, Dragonic!" Tsukasa yells at the dragon but he just freezes up, actually having a PTSD moment. "Dragonic?" No responses from the dragon.

Evol immediately presses the button as he thrusts it next to the top that his lever is at as it announces. "OVER THE EVOLUTION!"

He begins twirling the lever as the belt starts announcing excitedly. "REVOLUTION!'' It is playing a different music, more rapid and mechanical. The Gyro gear manifests but is now silver, spinning around until unfolding back into three pieces that spin around the user, on the top, center and bottom. Soon swirls of black tornado forms around the gears as well as black cubes with purple spots, releasing purple electricity.

"ARE YOU READY?!" The Evol Driver announces as Evolto utters out, spreading his arms forward. ''Henshin!"

"BLACK HOLE! BLACK HOLE! BLACK HOLE!" The Evol Driver chants as the cubes all slam themselves over him, overlapping and becoming a large rectangle-like box before utterly vanishing by being sucked up in the center as a white sphere. Tsukasa looks puzzled as only a mere 2-3 seconds pass before the hole suddenly reappears and expands, blasting away all the boxes and what emerges is Evol, in his final form. "EVOL BLACK HOLE! REVOLUTION!"

Evolto begins laughing as black swirls of wind wraps around him and blows like a tornado, actually blasting both Tsukasa and Dragonic out of the building and sending them flying high into the blackened sky. The dragon snaps back, flapping his fingers and negating the wind instantly. He then flies to Tsukasa and catches him, setting him down to the ground.

''S-sorry, I froze up." Dragonic apologies, breathing heavily. Tsukasa looks at him, for once showing a face of concern. He has never seen Dragonic act like that before. Why would he just freeze up like that? The dragon still breathes as he suggests to him. ''Tsukasa, use Decade Complete.''

Knowing this isn't the right time to talk about it, Tsukasa nods as he doesn't need to be told twice. He swaps the Decadriver with the K-Touch and activates it.

"KUUGA, AGITO, RYUKI, FAIZ, BLADE, HIBIKI, KABUTO, DEN-O, KIVA!'' The K-Touch announces one by one of each main rider's names as their logos glow until they all flash, including the Decade one. Tsukasa then presses on the F letter on the screen. ''FINAL KAMEN RIDE!''

Tsukasa wipes his hands as he transforms into Decade's final form. ''DECADE! COMPLETE!'' Decade looks forward as he watches Evol approach him slowly, actually snickering ominously as his body erupts in black aura. He raises his right hand and hand taunts him to come at him. "Bring it."

Scoffing, Decade comes charging at Evol who just stands there, now laughing as Decade swings the first fist and Evol easily catches it without a problem. Suddenly, Decade is lifted into the air by Evol's superior strength and pushes him away, blasting upward into the sky. Evol holds up that same hand and fires a dark black hole sphere right Decade with such speed and it quickly explodes in close range of him.

Evolto laughs at this until the Decadriver announces. "RYUKI! KAMEN RIDE! SURVIVE!" He staggers, looking up just to see emerging from the smoke of the explosion is Dragranzer as Decade and the holographic Ryuki Survive riding on top of it as they swing their sword weapons and unleash waves of fiery energy slashes at Evol. He scoffs as he literally jumps and flies at them, swinging his fists at the waves and unleashes a barrage of punches through the waves. Evol then flies right at Dragranzer and punches it across the face that a mini black hole forms and sucks the Mirror Monster and all riding on top of it inside of the hole, crushed into nothing.

Evol continues laughing as he has-

"KABUTO! KAMEN RIDE!" Evol staggers as he turns around and Decade is right behind him in midair along with a fake Kabuto Hyper. "HYPER!" Both riders use Hyper Clock Up, bashing their fists and punching Evol into the ground before they do a Rider Kick and kick him into the ground.

''READY GO! BLACK HOLE BREAK!'' The ground trembles as violent dark energy blasts, sending Decade Complete flying out of the ground and Evol floats out of the ground, posing menacingly as he hovers in the air. Decade lands on the ground as he presses on the Kuuga symbol of the K-Touch.

''KUUGA! KAMEN RIDE! ULTIMATE!" The K-Touch announces as Kuuga Ultimate manifests beside Decade and both leap at full force at Evol. Both Decade Complete and Ultimate Kuuga swing a powerful, Ultimate punch at Evolto who quickly catches both fists with the palm of his hands, resisting their powers.

"What futile!'' Evolto begins declaring as his pink-like visor eyes glow and forms small spheres of black hole energy in between his palms before they unleash powerful, destructive beams. The holographic Kuuga is destroyed while Decade is launched into the air as Evol flies at him with such speed, kicking him across the gut and then smacks him hard into the ground. "Do you want to hear this? Well let me tell you: I AM THE STRONGEST!''

Decade, grunting in agony, crashes hard on the ground, de-transformed as Tsukasa is bleeding from his head. He struggles to get up, glaring up at Evol who descends before him.

''It seems you're at your limit.'' Evol proclaims as he grabs the lever and spins it around, the same machine-like music playing as he's charging up for his Finisher.

"ARE YOU READY!" The Evol Driver announces as Evolto gets in a crouching pose, about to jump and deliver the finishing blow and kill this so-called destroyer.

"NOW YOU-'' Evol begins to declare loudly before suddenly he is shocked by a jolt of energy. It doesn't bother him much as he looks down and it's coming from his Evol Driver as more electricity flies out of it.

"What is... happening?" He questions, finding this extremely odd as he stands up straight. The electricity intensifies as Evol can hear… a count-

Suddenly the Evol Driver glows and explodes upon him. Evolto screams in surprise and agony. ''WAAA!'' He's blasting away as his transformation is undone. Tsukasa has a surprised expression as Evolto gasps in shock, reaching at his driver and it's completely destroyed along with the Evol Trigger and the Build System bottle. The only thing not destroyed is the Cobra Fullbottle.

''IMPOSSIBLE! M-MY DRIVER!'' Evolto actually screams in horror and dismay, showing an expression of dread for the destruction of his belt. Tsukasa is still confused as a voice calls out to him. "Tsukasa-san!'' He turns to see A.R Sento running up to him, breathing heavily but smiles. "It worked!"

"… Did you-'' Tsukasa begins to realize what he did but he beats him to it, explaining. "Yes. I set up a self-destruct in the other belts if they fall in evil hands, including the Evol Driver! Just like how Evolto destroyed both Sclash Drivers, I trigger that same system to destroy his driver. Thanks to the other me, I figure out how to activated it using his own power against him!''

''WHO TOLD YOU TO DO THAT?!'' Evolto screams in fury, despising what this Sento has done; much more humiliating than his Sento. He grabs at his destroyed driver, causing him to toss it to the ground and immediately complains, enraged and furious. "How could I lose my Evol form by a damn, spineless weakling?! This is impossible!''

A.R Sento gulps until Tsukasa protests. "You're wrong!"

Evolto raises an eyebrow as Tsukasa begins to breach one of his speeches. "Underestimating the naïve is underestimating yourself. Those with kind intentions, with naïve ideas; have the potential to overcome the odds thrown at them and defeat any in their way. They don't underestimate who they fight or come across; they face it head on with all their strength and put it all on the line. To show they have value to live in this world."

Raising his right arm and then lowering it, pointing his finger at the villain, Tsukasa declares with a determined expression. "Someone like you who underestimates everyone, who doesn't value anyone, can't understand what led to your defeat. That is why you will always lose to any Sento or myself because we fight for everyone, for humanity's future!''

"…" Quiet, Evolto looks at him and slowly cracks a smirk. How ironic? Humanity, once again, astonishes his expectations.

"Hmm, interesting theory. I guess you're right.'' He responds to Tsukasa's speech… and Tsukasa just drops his confidence and guard with a surprising expression. This was an actual first.

''… I wasn't expecting that kind of response.'' He mutters, never getting that kind of response, ever. It's usually "WHO THE HELL ARE YOU" or something like that but never like this. It's… really uneasy.

"But I will not tolerate losing my evolution, my form due to you humans! I'm done being nice.'' Evolto then declares, not going to forgive them for what they did to him as he pulls out the Transteam Gun and loads the Cobra Fullbottle.

"COBRA!" The weapon announces as he presses the trigger. "MIST MATCH!" Black mist forms around him, releasing electricity before transforming Evolto into Blood Stalk with fire crack glows all over him temporarily. "COBRA! COBRA! MIST MATCH! FIRE!''

A.R Sento startles, not familiar with this while Tsukasa smirks, rather astonished he still has another form.

"Now I will kill you two after this Sento builds me a new Evol Driver and then devours this damn rock of a planet!" Blood Stalk proclaims strongly to regain his powers once more.

Tsukasa grunts, proclaiming as he adjusts his vest. "This guy is really full of himself." He turns to A.R. Sento and asks of him. "Then I'm going to need your help, Sento."

A.R Sento startles, frowning as he shouldn't but after what the other Sento and Tsukasa said; he wanted to no longer feel pity for himself but be better.

"… I'll help you, Tsukasa-san." He responds, not going to let him down. "Together, we'll win.

Tsukasa smirks as he proclaims mainly towards Evolto. "You're right, we will. After all, I am the passing-through Kamen Rider." He points his finger at the villain. "Remember that!"

He pulls out a Rider Card, ordering his assistant. "Let's go Sento! Show me how a true scientist fights!"

Sento nods, strapping on his Build Driver and shakes both Fullbottles before sliding them into his driver.

"RABBIT! TANK!" The Build Driver begins announcing. ''BEST MATCH!" He grabs and spins the lever as the half-bodies form in front and behind him. "ARE YOU READY?"

"Henshin!" Both Tsukasa and A.R Sento shout as Tsukasa thrusts his Rider Card into his belt.

"KAMEN RIDE! DECADE!" The Decadriver announces as he transforms into Decade.

''THE FULLMETAL MOONSAULT!" The Build Driver announces as the half-bodies fill up in fluid and slam themselves onto Sento, transforming him into Build. "RABBITTANK! OH YEAAH!"

Both Riders immediately charge at Blood Stalk who summons his large energy cobras, slithering at them. They dodge around their swift attacks, trying to coil or bite them.

"You think you mortals have any chance against me?" Blood Stalk mocks the two, coming at Build who both swap fists and arms, sparks flying out through each clash. "Don't make me laugh! I've been laughing since we've met!"

"Of course we do! You showed me to trust in others even if you deceive me." Build proclaims strongly, kicking him which Blood Stalk kicks back as more sparks fly out but Build actually pushes him back. One of the energy cobras tries to attack him, which Build rolls and evades. "That's why I won't give up on that ideal and keep fighting with that hope for humanity!"

He comes charging at the cobra and swings a fist, punching it across the head and pushes it back.

"We will…" Build begins to say, squeezing his fist as he just wants to do right for the world, to use his science to protect what matters. "Fight for that world we love! That world of peace!"

Decade leaps back from the cobra' lounge as his Ride Booker glows and shoots out multiple cards that he grabs. He eyes one of them and responses. "My thoughts exactly." As he thrusts the card into his belt.

"FINAL FORM RIDE!" The Decadriver announces as Decade gets behind Build and warns him. "This might tickle.'' As he shoves his hands into his back.

Build soon gasps as his body suddenly unfolds and becomes a red-blue weapon that resembles the Fullbottle Buster with a small Gatling-like attachment on the top. It also forms leg armor that attaches itself to Decade, a mix of red and blue colors as well as tank tracks, feet and armor tank arms with a pair of jet-like boot wings on his shoulders. "BUILD!''

"Oh, how cute! You think this will-'' Evolto begins to mock Decade until he dashes forward with insane speed as a red blur, stunning him before Decade delivers not just an arm bash and then swings with his sword, slashing him across the chest. Sparks fly out from the staggered Blood Stalk as Decade moves around him with swift speed while he fires a barrage of rapid shots from the Gatling weapon. Multiple sparks fly out all over Blood Stalk, dropping on one knee.

The energy cobras come at them but Decade dashes around their attacks with his increased speed and then he bashes his left fist through one of the cobras, penetrating through its body and destroying it. He then swings the weapon and cuts through the last cobra in half, destroying it.

"This is…" Blood Stalk begins to utter, pulling himself up actually mad. "I will not tolerate this! I refuse to lose to you humans again!"

"Sadly, that's exactly what will happen." Decade speaks up, pulling out a Rider Card and dunks it into his belt. "Time to end this nightmare." He pushes one of the levers of his belt forward.

"FINAL ATTACK RIDE!" The Decadriver begins to announce as Decade takes aim with the large weapon, swirls of blue, red and magenta color energies building up from the barrel tip of the weapon as he takes aim. He soon fires the trigger of the weapon, firing a destructive energy shot. "BUILD!"

Blood Stalk, still too stunned to get away, is forced to punch the blast as it instantly consumes him and explodes on impact. Decade watches this, breathing heavily as the weapon reverts back to Build and he reverts back to normal.

The real Sento just arrives, saving the last of the transformed Smash and watches as Blood Stalk survives the attack as his body begins to disintegrate. Panting heavily, Evolto can feel his life is fading away fast. Clenching his fists, refusing to admit defeat, he stands back up and proclaims. "T-this will not be my end!"

He starts dragging himself forward, gasping as his body is becoming light but this is not letting Evolto from getting the last laugh.

"You understand…" Evolto begins to utter as his body starts cracking. "Humanity, your despair…'' He soon cracks and explodes in menacing, psychopathic laughter. "WILL NOT END WITH MY DEATH! I SWEAR IT! HAHAHAHA!'' Soon his body couldn't hold it in and self-explodes, shattering into nothing.

Sento looks away, frowning and upset. Build looks down, rather sad too while Tsukasa sighs, glad this is over. Dragonic continues staring at where Evolto exploded, wondering what- who the hell he was to speak of despair like that. Only one other person speaks about it to such a degree… and it frightens him... and the idea of the Evolto of his world. May... may he be lost for time or else.


Soon things began to become normal but after the experience with Evolto, A.R. Sento contacted all the world powers in his world and made the choice to seal away the Pandora Box. Many oppose but Sento disagrees, strongly believing the box will bring others like Evolto to threaten their world. Ultimately, they saw his point of view and accepted it. Sento didn't express it but he was glad to be acknowledged.

"So now you'll be leading to disposing of the Pandora Box?" Tsukasa asks his former assistant who nods with a smile. "I think humanity benefits from always being united rather than relying on something that will lead to discord. That's what the Professor- what Evolto taught me."

He makes a sad face but changes it as he looks at Tsukasa, praising him too. "And what you taught me most of all, Tsukasa-san."

Tsukasa smirks, happy to hear that as he raises his hand to him. Sento startles before he smiles, shaking his hand.

"Good luck, Sento." He tells him but he snickers, correcting him. "Sento is an alias. Takumi is my real name."

Tsukasa already assumes it was an alias but he much prefers that name… that and he doesn't want to confuse him with the other Takumi.

"I prefer Sento." He admits to him which he replies back with a small grin. "I also prefer Sento."

With that, the two parted ways as Tsukasa and his group walked away. Tsukasa does look back; watching Sento and his friends pick up the pieces of the building and are going to make their world better without that box. He scoffs with a small smirk, taking aim with his camera and takes a picture of the moment: Showing that humanity will always advance forward by supporting each other.

The group walks away from the building and the real Sento is waiting for them, smiling as he immediately apologies. ''Guess I should apologize about before.'' He coughs, wanting to put it in the best of words and does, telling Tsukasa. ''You really are a hero."

"And you're a stupid hero, Genius Boy.'' Tsukasa tells him as a taunt. Sento rolls his eyes, complaining a bit. "If Banjo heard that, he would be laughing and agreeing with you. That idiot.'' He then looks back at Tsukasa and sighs, becoming serious. "But now it's time to settle things, Decade."

This surprises Natsumi as Sento explains his reasons. "I still made a promise to stop Dark Decade and it seems from Sougo, you fought the other past riders including Ex-Aid.''

Natsumi eyes Sougo, surprised he even told the main Sento about all of this.

Strapping on his Build Driver, Sento soon declares, almost egotistically. "Let's see which one of us is destined to be the hero of the multiverse!"

Tsukasa oddly cracks a smirk, already wearing his Decadriver as he accepts. "Fine but no warm ups."

Sento curls a small smirk to hear that as he pulls out a large white, golden Fullbottle.

"My thoughts exactly.'' He replies as he taps on the top of the large Fullbottle. "Now, let's begin the final experiment."

"GREAT!" The Genius Fullbottle begins to announce itself as Sento twists the cap open. ''ALL YEAH!" He thrusts it into the Build Driver. "GENIUS!" Sento then begins twirling the lever of his driver. Suddenly metal parts and tubes form to resemble a stage that Sento is standing on followed by multiple tubes surrounding, pumping the tubes. ''YEAH! YEAH! YEAH! YEAH!"

Tsukasa pulls out the K-Touch and swaps it with the Decadriver before activating it.

"KUUGA, AGITO, RYUKI, FAIZ, BLADE, HIBIKI, KABUTO, DEN-O, KIVA!'' The K-Touch announces one by one of each main rider's names as their logos glow until they all flash, including the Decade one. Tsukasa then presses on the F letter on the screen. ''FINAL KAMEN RIDE!'' As he pulls out a Ride Card.

"ARE YOU READY?" The Build Driver announces as the setup is ready.

"Henshin!" Both Tsukasa and Sento shout as Tsukasa dunks his Rider Card into his belt.

''DECADE! COMPLETE!'' The K-Touch and Decadriver are announced as Tsukasa transforms into Decade Complete.

As that happens, golden bars move and surround the sides of Sento's body as a golden chest piece forms on his chest, resembling Build's symbol. His body glows and now wears a white full body rider outfit that resembles Build with a black skintight underbody. The helmet also has a white crystal clear orb on the forehead. As he does transform, each of the tubes are filled with colorful different colors.

"THE TOTALLY FLAWLESS BOTTLE BRAINIAC!" The Build Driver begins to announce as the bars connect to the form with yellow sliding tubes that inserts the other colorful tubes onto the new Build form onto the arms, shoulders, back sides, forearms, legs and even the head as the new visors followed by different color small long tubes forming across Build's body, connecting them all throughout the body. "BUILD GENIUS!" The stage and everything vanishes as the new Build suit glows as well as each bottle. "AWESOME! REALLY AWESOME!"

Not wasting time, Decade twirls the Ride Booker in gun form and fires a barrage of magenta energy shots. Build just stands there as the hits seemingly connected but Decade startles, able to tell Build to swipe them with insane speed similar to Evol Black Hole's speed.

Decade quickly switches his weapon into sword form and swipes the blade with his free hand, coming at Build with a powerful swing… that Build bashes the sword swing so hard it knocks the weapon off his hand. This shocks Decade as Build then stomp kicks him backwards before vanishing as a blur of different colors. Decade barely reacts as Build reappears behind him and slams his fist across his back, launching him further and then Build dashes with insane speed, punching Decade left and right like a ping-pong ball before roundhouse kicking him through a tree, crashing hard onto the ground.

Natsumi watches in dismay as Decade Complete is actually grunting, sparks still flying out across his suit.

''Tsukasa-kun is still damaged from the last fight!" She affirms that he hasn't fully recovered from his fight against Evol. Dragonic frowns, feeling responsible for this one but Sougo says. ''He knows what he's doing, Natsumi.''

Natsumi eyes him and notices the fixated look across his face towards Decade, muttering out firmly. "He must win."

That look worries her as she hasn't seen him act like this.

Decade stands up, panting as Build walks towards him as he twirls the lever of his belt once.

"ONE SIDE!" The Build Driver announces while the bottles and tubes attached on the right side of his body as well as the left side of his visor and left leg begin to glow in bright red-yellow-pink light as the right side of his chest logo glows too. "READY… GO!" He charges forward with such intense speed that he's already punched Decade across his chest. "GENIUS ATTACK!" His fist releases the same color brightness across Decade with each wave, heavily stunning and damaging the magenta rider.

''W-what the hell…" Decade utters, sparks of electricity damaging him more, almost like splitting his atoms in half. He tries to move but Build picks him up by the collar.

"Is that the best you got, Destroyer?" Build asks him before he punches him with his other hand over and over, sparks flying out across him. Decade grunts in more pain but resists as he kicks him off him while launching him to the dropped Ride Booker and grabs it.

"Hardly." Decade proclaims, pulling himself up as he dunks a Rider Card into his Decadriver.

''FINAL KAMEN RIDE!'' The Decadriver announces as Decade taps on its faceplate and begins to glow. ''KUUGA ULTIMATE!'' Swirls of darkness and golden electricity consume him before he emerges as Kuuga's final form, somersaulting and slamming his feet on the ground.

Build snickers as he comes dashing at him only to get gut punched by Decade-Kuuga in an instant once he's in ranged. This shocks the rider, unaware that Ultimate Kuuga shares the abilities of all other Kuuga forms and that includes Pegasus Kuuga's precision sight. Decade then unloads a barrage of punches across the stunned Build before kicking him hard onto a tree.

"They're evenly matched now!" Dragonic announces with a smirk to Natsumi's relief.

Build breathes loudly, not expecting that would hurt as he twirls the lever of his driver once.

"ONE SIDE!" The Build Driver announces as now the left side of the bottles and tubes glow in bluer colors as well as the right side of his visor helmet, his right leg and the left side of his logo crest. "READY… GO!" Build dashes so fast right in front of Decade, faster than Kuuga's precision and kicks him across the fist. "GENIUS BREAK!"

The blow pulse waves of blue sparkling energy and would have kicked Decade right into the wall… but it didn't as Decade taps into the Ultimate Darkness and repels Build's kick to his shock.

''You're going to need to try better, Genius Boy!'' Decade shouts, raising and thrusting his own kick and connects, releasing a wave of black energy that blasts Build back but he resists it partly.

''That's fine with me!'' Build shouts, charging at him as he engulfs his right fist with sparkling rainbow energy.

Decade-Kuuga clinches his own right fist, swirls of dark energy wrapping around it before he throws it at Build's fist. Both punches clash as torrents of rainbow colored and dark energies collide. Everyone braces themselves as Decade and Build continue parrying fists while evading attacks from the other.

Decade-Kuuga quickly summons the Titan Sword, swinging it at Build who replies with the Fullbottle Buster he just summoned, clashing it. Both weapons grind upon the other, sparks flying out.

"Well, guess we're tied-'' Build begins to agree with the dragon's statement only for Decade-Kuuga suddenly summons Kuuga's Pegasus Bowgun with his free hand, blasting Build Genius across the chest so hard it slams him back onto a wall, crashing through it.

"No, not really." Decade disagrees as both weapons vanished. He watches as Build emerges out of the wall, looking damaged. ''Hope you're done for.''

"Not… yet." Build, however, protests as he pulls out the Hazard Trigger. "Not even close! The law of victory have been decided!'' He presses the button of the device before attaching it onto his driver similar to the Evol Trigger.

"HAZARD ON!" The device announces as Build begins to glow across the tubes and bottles, radiating his body with more energy. He suddenly dashes at Decade with greater speed, swinging a punch that Decade barely dodges but not the Fullbottle Buster slashing him across the chest twice.

Sparks fly out as Decade-Kuuga staggers back, gasping in pain. Build then punches at him but he counters with his own punch, both attacks clashing but this time Build's pushes Decade backwards.

Decade-Kuuga summons the Dragon Rod, coming at Build who swings the Fullbottle Buster. Both weapons clash but Build pushes his increased power onto his weapon, literally cutting through the rod but Decade then uses the chance to punch the weapon on the side, cracking and destroying it while pushing Build backwards.

"Where did this power come from?'' Decade comments by Build's sudden power. If this fight goes on any longer; he's actually going to die, again. ''No… It ends here.'' Decade proclaims, going to end this. He pulls out two Rider Cards, going to decide everything on this as he thrusts one of them into his Decadriver.

Seeing this, Build isn't going to hold anything back as he twirls the lever of his belt. ''You're right, it does end here!'' He declares, twirling the lever a lot. "For Love and Peace!"

''ONE SIDE! FLIP SIDE! ALL SIDES!" The Build Driver begins to announce as all the bottles and liner tubes across Build's suit glows in a different color, resembling a rainbow. "READY GO!" Build leaps upward.

"FINAL ATTACK RIDE!" The Decadriver announces the Mighty Ankles manifests around Decade-Kuuga's right foot as he performs Kuuga's signature prep pose before he runs forward and jumps right at him.

"GENIUS FINISH!" The Build Driver then announces as Build performs a Rider Kick and jets downward at Decade, each bottle releasing steam of rainbow color energy.

"KUUGA!" The Decadriver announces as Decade is engulfed in dark energy from the Ultimate form. Soon the two opposing glows collide and clash, streams of rainbow and black energies slam themselves onto the other. Everyone watches as the spectacle looks amazing. However, Decade grunts as he pushes all of his power into his kick but Build does the same as the red device begins to glow brighter.

"HAZARD FINISH!" The Hazard Trigger announces as the rainbow energy of Build grows and intensifies larger. It begins to consume and overlap the darkness of Decade-Kuuga. It seems the fight is over… Until Decade thrusts the second Rider Card into his driver.

''FINAL KAMEN RIDE!" The Decadriver announces as golden light surrounds Decade-Kuuga, transforming him into Ultimate's stronger form. "KUUGA RISING ULTIMATE!"

Suddenly he radiates and explodes in black, golden energy that instantly overpowers Build's power and kicks right through him. Everyone watches speechless as Decade-Kuuga lands on the ground first and Build is instantly consumed in a destructive pillar-shaped explosion, shown piercing through the atmosphere.

Decade breathes heavily, de-transforming. Tsukasa turns as the explosion dies out quickly and Build hits the ground hard, also reverted into base form. Still breathing, Tsukasa drags himself and looks down at the defeated Sento, lying on the ground and his body is already turning sparks of light.

Smiling, Sento utters out weakly. "You're… pretty destructive… for a hero."

"And you're worthy… of being called a built hero, Sento." Tsukasa responds back, grabbing his left arm on the forearm of his right arm.

Sento smiles to hear that, looking up at him as the light covers more of his body

"Hey." He begins to say, pleading to Tsukasa. "We're counting on you, Tsukasa."

Tsukasa looks at him and nods, not planning to fail on all those he fought, learn and earn a piece of their souls into his own. Sento smiles before his body fully glows and dissolves into sparks of light.

"Tsukasa-kun!" Tsukasa turns around to look at Natsumi running over towards him with Jigglypuff floating ride beside her. He smirks weakly, telling her like this is no issue. "I-I'm fine. Stop worrying so much for-''

Layla then has a vision of danger and panics, running to Natsumi. It's too late as suddenly something swoops down and grabs Natsumi to everyone's alarm as well as blowing the pink balloon away, crying out. Natsumi startles as she soon screams, soaring upward into the sky by force.

"NATSUMIKAN!" Tsukasa immediately yells, glaring as it is Doctor Shinigami who grabbed Natsumi. Layla barks, not able to hit him while he has Natsumi in his arms.

Dragonic watches silently, not even flying up to save Natsumi as he can feel the aura of the Fangire and understands what he's doing. He does eye Sougo, not going to do anything either and he knows why.

"LET GO OF ME!" Natsumi screams, struggling to break free but the Fangire easily has a strong grip on her all while chuckling with small hiccups.

Struggling to move, Tsukasa utters out angrily. "Let go… of Natsumikan right now, Doctor Shinigami!"

"Oh no can't do it, my boy." The madman doctor expresses eagerly. "I have plans for her. Of course I'll let you save her if you come to the World of Negative."

Tsukasa glares madly, not naïve to know this is Dark Decade's doing to lure him to his world.

The evil doctor snicker as he proclaims. "I'll see you there then. Time to go, Kiva-la-chan."

"Pardon me~!" Cooing, Kiva-la flies up and swoops around the Fangire. Layla barks while Jigglypuff cries angrily.

''Should have known." Tsukasa mutters coldly, always having a feeling that bat was playing a spy for someone.

''Oh don't look at me like that, mooch~." Kiva-la expresses kindly. "I actually like Natsumi-chan too!''

Tsukasa just glares madder.

''See you soon, Decade." Doctor Shinigami proclaims as an Aurora Curtain forms above him. He flies up into the portal all while Natsumi is still struggling, trying to reach out with her arms to Tsukasa.

"TSUKASA-KUN!" She screams out until they go inside the portal followed by Kiva-la. Soon the portal closes up shut to everyone's dread, except Sougo who stares calmly.

''…" Silent as he breathes angrily at his own powerlessness, Tsukasa drops on his knees and slams his left fist onto the ground, yelling out furiously. ''DAMN IT! NATSUMI!''


Author's Note: Time to clarify things:

1) This is now full on Fanfic territory, using elements from the Decade series from the TV Series, Movies and even Novels (which I already used so yea).

2) … Build is FUCKING GOOD. Probably the best written plot story and characters too. Build, in my eyes, is like the Magnum Opus of Kamen Rider. Yes, many people say that Build is like W or Drive but honestly… no, not at all. It combines many aspects of each rider show and creates this grand play. IT'S THAT GOOD! If you have never seen a rider show or like only wants to watch 1 at the least; I'll say start with Ex-Aid or Build. For me, I watched Build last and it was WORTH IT! Sorry Zi-O, the writers and director should have tried harder.

3) Sento Kiryu (not even his real name for those who never watched Build) is a cool if not probably my favorite hero. He has traits you would see from Tendo and Tsukasa but follows the "I am the good guy" type of rider like Eiji, Kouta, Emu, etc. Plus his story is both a tragedy but also why the World of Build is the way it is. Regardless, he is the Hero of Justice "Love and Peace" and he loves bragging about being the main hero, his intelligence and how science and being heroic can save the world. He's like a mix of Tony Stark from the Iron Man Iron Adventures and young adult Ben Tennyson from Ben 10. He takes on a lot and does his best to save his world and the people around him. To me, that's a hero; one who fights for Love and Peace.

And what makes a good hero... is a terrifying villain.

4) Evolto/Evol… There have been many-MANY Rider villains I've seen. Some better than others (The Foundation, ZECT (eh), the Greeed, Horoscopes, Roidmudes, Cronus) and some REALLY BAD (The God of Darkness, Odin (a total waste), Wiseman (his plan mainly), Makamou (WHAT IS THEIR PURPOSE?!), stupid Kai (should have been Gaoh, HE'S WAY BETTER)) but other than Cronus who I enjoyed and would rank Number 1; that changed when I met this asshole who's AWESOME. I fucking love Evolto/Evol/Blood Stalk. He's the best! LIKE, without spoiling; he's the reason why the World of Build was the way it was and how Sento was "born". TRUST ME; this guy is evil, he loves entertaining with his prey, screwing with their heads and still STUPIDLY STRONG. He's Marvel's Galactus but with a personality! He's Thanos with humor. And his power is so OP! BLACK HOLES?! HOW DO YOU FIGHT BLACK HOLES?! I love him and his signature catchphrase: Caio… after he hits or kills his target or he trolls others. Even his need to have a sofa chair to sit on like a throne chair. I love him. Best Rider Villain. I mean it. Like many will say his plot drop after becoming Evol but they're wrong. He had no reason to hide or scheme; he became THE final boss and it worked PERFECTLY.

Also, master manipulator and just as smart as Sento if not more. AND IMMORTAL?! If I told you how he died, you would not believe me because there was no way out.

5) AND YES, just like A.R. World of Ex-Aid; why NOT make canon Evolto as the main threat. People would complain if I didn't do it. I did it for Kuroto, might as well do it with the other strongest rider and give Tsukasa a run for his money. GEEZ. Brutal.

6) Though… it is kinda weird why Dragonic began to freeze up by Evol when he mentioned a certain word: Despair. Or Evolto's sudden increase in power. Hmm…?

7) Cliffhanger, Natsumi got kidnapped, again… So guess where Tsukasa has to go to save her? And no, it's not the World of Zi-O.


LONGEST TWO-PART CHAPTER. SO LONG!

The A.R. World of Build, which was good, is the last world for Tsukasa and group and now their next and last destination is the World of Negative to save Natsumi from Doctor Shinigami and fight Dark Decade…

However, in 2 weeks, Daiki will have his own little journey as he travels to the A.R. World of Zi-O. SURPRISE?! Why hmm? Hmm… I have my reasons and you'll see what I mean soon. See you there!
