Sento: Civil war breaks out over Pandora's Box and the massive amount of energy within it. Kamen Rider Build, Kiryu Sento is completely defeated by the overwhelming power of Evolt, who fused with Kamen Rider Cross-Z, Banjo Ryuga. And finally, Evolt opens Pandora's Box!
Kazumi: Kamen Rider Build, the end! Starting this week, it'll be a love story between Kazumin and Miitan, called "Love and Date the Idol Otaku"!
Sento: No, it won't! Besides, you've already mentioned the same thing in the other recap! Why am I even using the old recap to begin with?! Anyways, what'd you go and come up with a title for? You never even answered my question earlier!
Kazumi: We're in a different show after all!
Sento: New name then! Build is still the lead character in episode 1 of Kamen Rider Build: The Stranded Scientist! Hell, it's even in the title. Let's begin!
Kazumi: How are we even speaking English to begin with?


"Now Nanba's waging a war against the world? I was right." Evolt merely laughed at Sento's struggle, fighting in TankTank Form whilst Evolt continued to utilize his newly-earned second phase, EvolDragon. Utilizing the Beat Closer summoned through his armour, he pulled on the end of the weapon once, preparing an attack.

[HIPPARE! SMASH HIT!]

As Sento fell down backwards, having been clearly nearly drained of his stamina, Evolt simply continued his rant on humanity's greed. "There's no limit to the greed of humanity, and that's not even including your foolishness." As Sento struggled to stand up after having been attacked, he simply gritted his teeth, stating, "That's not true! We'll put an end to this useless war!" Sento then took out the Pandora Panel FullBottle that he had made the previous night, about to utilize its power, before he stared at it, reminiscing at the words that Misora had told him before he charged into battle, when she found out about its effects.

"Why can't I get through to you? Why don't you value yourself more?" He only remembered himself comforting Misora's cries, as he tried to reassure her the best he could that the war would finally end.

Sento, having finally stopped grieving at the sadness he'd bring to Misora, only stated to himself, with her in mind, "Sorry... I have to protect everyone and bring peace back. Nothing is more important than that..." As Sento focused on the situation at hand, Evolt having not attacked him yet, he then took out the FullFull RabbitTank Bottle from the Driver, readying the Pandora Panel FullBottle, as he shoved it into the Driver, the gyro on the belt flashing a steady stream of white, and the Panel coursing multiple colours as it awaited his transformation.

As he began to pull on the crank of the Driver, the effects of the FullBottle began to take control of him, causing multiple blue jolts of electricity to begin coursing through the Build Driver, and subsequently into the Ride Armour, causing Sento to scream in pain. Evolt had merely stared on at Sento's transformation as he continued pulling the crank, the jolts of electricity continuing to take control of his body. However, gaining his resolve, Sento painfully responded, "Build Up!" as he readied himself for his next move. Unleashing all of the built-up electricity that had been coursing through his body, the electricity would be unleashed all around Sento, causing miniature explosions, as Evolt slashed the ones heading in his direction using the Beat Closer.

"This is..." Evolt noticed something off with Sento's upgraded transformation, as he stared onto Sento, who had been walking towards him, seemingly rejuvenated as if his previous attacks on Sento weren't having any effect on him. As Evolt sent the blade down onto Sento's shoulder, it merely collided, letting out tiny sparks; however, Sento didn't budge, causing Evolt to suddenly stop his attack in surprise, also gaining the attention of Kazumi, who had just finished defeating his fair share of Clone Smash and Hard Guardians.

And on command, Sento then punched Evolt with a force hard enough to land him in the nearby body of water, along with his blade. Sento merely stared at Evolt, a newfound strength showing itself, as Kazumi could only ask in shock to himself, "What's going on?" As Evolt crawled out of the small body of water, he'd merely comment on Sento's newfound strength, "Hazard Level 6. So you've finally surpassed human limits?" As he sat up, gaining his composure back, he'd merely continue his statement, "Well done, Sento. So you're another one of those foolish humans."

As Sento stared on, he simply asked regarding Evolt's sudden statement, "What do you mean?" Evolt then stood up, facing in Sento's direction as he then asked, "Why do you think I caused this war?" He stared at Sento maliciously as he then replied to his own question, "So I could use you to restore my own power!" As Sento gasped, on the road to realizing the truth about something far more malicious than he imagined, Evolt took out the incomplete Evol-Trigger, holding it in his left hand, as he then continued his talk, "For a human, there's a limit to how much of the energy in this that can be used." Walking towards Sento, he would then continue, "That's why I took advantage of the power of science. If a war began, you'd have no choice but to strengthen the Rider System, whether you liked it or not."

Sento then realized the truth behind Evolt's continuous asking of him upgrading, even before he knew of his true identity, and he stared at his own armour, reminiscing on the major upgrades the Rider System had undergone ever since he first gained many months prior to the present.

The FullBottle purifications that he, Soichi and Misora had been doing before the reveal of Soichi's true identity as Blook Stalk and subsequently Evolt, in particular the Touto set of FullBottles.

[HAGANE NO MOONSAULT! RABBITTANK! YEAH!]

The creation of the RabbitTank Sparkling FullBottle, utilizing the RabbitTank Best Match and the Pandora's Box FullBottle, and subsequently its first usage against Blood Stalk in the alleyway he had been 'found' at by Evolt.

[SHUWATTO HAJIKERU! RABBITTANK SPARKLING! YEA-YEAH!]

The Hazard Trigger that Evolt had given him which had come with massive strength, and berserker-murderer effects, and subsequently his first fight with it against the multiple Hard Smash that Hokuto's prime minister, Yoshiko Tajimi, had sent at him and Banjo back when Touto and Hokuto were at war with each other.

[UNCONTROL SWITCH! BLACK HAZARD! YABEI!]

The FullFull RabbitTank Bottle that he had created to overcome the berserker effects of the Hazard Forms, the speedy RabbitRabbit Form and its first usage during the 3-on-3 battle with Seito, the strong TankTank Form and its first usage to defeat Rogue during the same battle.

[KURENAI NO SPEEDY JUMPER! RABBITRABBIT! YABEI! HAEI!]

[KOTETSU NO BLUE WARRIOR! TANKTANK! YABEI! TSUEI!]

And lastly the Pandora Panel FullBottle that he was currently using, made from compressing a panel of the Pandora's Box to fit the Build Driver.

He could hear the transformation sounds accompanying each memory that he had of the powers that he had created, either as Sento, or as Takumi. Evolt then continued with his speech, "And with this power, you would become the ultimate Kamen Rider. That's what Project Build really was about!" As Sento stared at Evolt's grinning form, anger and hatred slowly seeping its way into his mind, he then barked back, "You caused a war for that?! What bullshit!" Dashing towards him, Sento would try to punch him with the newfound strength that he still supposedly had, only to be met with sparks forming from Sento punching Evolt's face, before he then flash stepped out of the way, punching Sento in the armour at the gut, and causing a hole to form in the armour, Evolt's hand inside it. Evolt merely taunted Sento's failure, "Too late! Everything went as planned!"

Sento stared at Evolt, unable to anything, the feeling of losing his own life force present. Kazumi, on the other hand, was horrified at the scene unfolding in front of him, and he dashed towards Sento and Evolt, screaming, "Evolt's fist is in Build!" As Evolt began to absorb the power of both Sento and Build, he'd then state, "I shall take Build, who has surpassed human limits and become complete!" Absorbing the power of Build, multiple surges of energy would fill Evolt's armour, and with that, suddenly, Ryuga's body would fall backwards, Evolt finally no longer possessing him. As Sento saw what had happened then, he simply grinned, painfully laughing, as he then stated, "I was waiting for that."

And on instinct, Sento would then pull the crank of the Build Driver once again, no longer having intentions of holding back as the Pandora Panel continued to course through a rainbow of colours, his Hazard Level rising and Evolt looking on in confusion. Sento would then state, "Measure my Hazard Level." Evolt, hand still absorbing Build's power, retorted in shock, "What?! 6.1! 6.2! 6.3! Impossible... it keeps going up!" A large surge of energy would then be released from the Build Armour, causing Evolt to reel in pain, and Kazumi to even be pushed backwards. Sento then continued pulling the crank, as he stated, "Thanks to Dad's experimental data, I saw through your plan!"

He then remembered Dad's research plan, intent on creating a device that could channel the full power of Pandora's Box to help him destroy Evolt once and for all.

Sento grinned, staring at Ryuga's unconscious body as he continued to pull the crank. "I pretended to fall into your trap so I could save Banjou!" Evolt, suddenly shocked at something he hadn't expected in the slightest, then suddenly asked, "Do you know what raising your Hazard Level so quickly can do?!" Sento, finally fully at his resolve, then shouted as his free hand then latched onto Evolt's hand, "Yeah! I'll perish with you!" Sento's rapidly rising Hazard Level caused his armour to begin dissipating, and he stared into Evolt, screaming, "This is the end, Evolt!" Evolt's armour too began to dissipate, asked in anger, "A human, deceive me?! Bullshit!" He would then grab Sento's other hand, the one that he had been using to pull the crank, but Sento would grab him with his free hand, latching onto him, as a bright explosion took place, fog surrounding the explosion soon after, as Kazumi shielding himself from the explosion.

As the mist dissipated, all that was left was Ryuga's unconscious body, the Evol-Driver and the incomplete Evol-Trigger that Evolt had been using, and Sento's Hazard Trigger and FullFull RabbitTank Bottle. However, neither Sento or Evolt were present, which only meant one thing; Sento had truly defeated Evolt, but at a heavy cost... Sento had truly committed a suicide attack.

And as Sento had finally defeated Evolt, potentially bringing peace to the Earth, there was a heavy cost... his own allies would bear the burden of not being able to save him; Banjo Ryuga for not being able to do anything, having being possessed himself; Kazumi Sawatari for not saving Sento before his own suicide attack; and Misora Isurugi, Sawa Takigawa and Gentoku Himuro for being unable to fight and protecting Sento, the most affected one being Misora herself. But was it the actual end of the story?


Sento's eyes suddenly jolted open, and his mind woke up, still confused as to what the hell actually happened. His body, just as confused as his mind, gave control to his mind, removing itself from auto-pilot, as the newly-awakened Sento tried to look around him, to no avail. As he began to stand up, he fell to the ground, sitting down, as he fully gained control of his body. It felt weird, like as if he had embraced death in the arms- oh wait, he did...! He was supposed to have died fighting Evolt! And even if Sento himself didn't die, he surely didn't fight Evolt in a place full of trees; he remembered that there were buildings and stuff. But as he felt his own body, another thing, something more wrong began to surface.

"Why am I alive? Why does my body suddenly feel like I'm eighteen years old?! Why am I suddenly able to fluently speak English, a language that I can only read well but not speak?! Am I even still actually able to speak Japanese?!" Sento sighed, as he tried to get some form of Japanese out, muttering to himself, "なぜ私はここにいるのですか?(Why am I here?)" A sigh of relief came out of Sento's mouth, thankful that he was able to speak Japanese at the very least. Standing up properly this time, he looked around him, trying to figure out where the actual hell he was at.

Looking around, he deduced that he was in some form of forest, judging from the trees around him that resembled forest trees. However, they felt almost unnatural in a way that was somewhat unnerving to him; the emerald green colour of the trees almost felt odd in a way that made him feel like he was in one of those weird video games that Ex-Aid could play. Anyways, continuing to look around, he noticed a weird building in the distance, that seemed like something that was definitely not Japanese in style at all; he saw a giant tower in the distance that seemed fantasy-like, and felt like something out of the Wizard of Oz.

However, deciding that heading to that tower was the best plan of action, or rather, the only sane option that Sento had. Besides, the lighthouse-shaped design the top of the tower had could potentially signal the presence of a town of sorts there; maybe civilization of some form, a place where Sento could actually get answers. However, as he was about to head in the direction of the giant tower, he then heard growls coming from the bushes and trees all around him, which definitely freaked him out a little.

Looking for a weapon of sorts to defend his new eighteen-year-old body, he then realized that the only things present with him, which were scattered on the floor in front of him without his realization, were his Build Driver and the Rabbit and Tank FullBottles, which definitely felt odd to him. As he picked them up, he then muttered a thought to himself, "他のフルボトルはどこですか?!(Where are the other FullBottles?!)" However, it wasn't something he could ponder on for too long, as he then noticed red eyes glowing from the same trees which produced the growling noises, leading him to realize that this was something far more dangerous than what he had expected.

Deciding to do the one thing he knew very well with the tools on hand, he held the Build Driver in his hand, equipping it on his waist, as the belt straps formed, its whirring signalling the Driver coming to life. Still worried at multiple things that had nothing to do with the situation, Sento found himself having to put those away temporarily as wolf-like figures would emerge from the bushes, with a look that clearly made it such that they wanted to kill Sento. Knowing that he had to be fast, he took out the Rabbit and Tank FullBottles, as he said to himself, "さ, 実験 を 始めよう か? (Now, shall we begin the experiment?)" Shaking the Bottles as fast as he could, equations began to appear around him, in the direction of the wolf-like figures, as they began to attack. Interestingly enough, the equations would damage them, causing them to be pushed backwards, as a weird shadow-like substance leaked from them.

Catching on to the fact that these weren't just regular wolves, he then twisted the caps of the two FullBottles, the labels being displayed on the front, and the essences ready to be utilized. He then inserted the two Bottles into the two Driver slots, as emblems of a red rabbit, and a blue tank would appear in front of the Driver.

[RABBIT! TANK! BEST MATCH!]

Immediately, letting out a deep breath, Sento pulled the crank of the Driver, as the RabbitTank Snap Ride Builder began to form around him, the tubes slowly beginning to fill with red and blye liquid. As the tubes fully filled up, the Rabbit and Tank Halfbodies forming on the Snap Ride Builder, Sento readied himself, as the belt chanted once more.

[ARE YOU READY?]

Entering his usual transformation pose, he then shouted, "へんしん! (Transform!)" And as if on command, the two halves of the Snap Ride Builder were pulled towards, as the Halfbodies snapped together, locking and forming the armour of Build, before multiple vents of Nebula Gas were released from the armour. Readying himself, he prepared for what was essentially the first transformation he'd have in this weird place.

[HAGANE NO MOONSAULT! RABBITTANK! YEAH!]

Readying himself for an interesting battle, his eyes would light up, as he then said, "の法則が決まった. (The law of victory has been decided.)" Immediately, he rushed into battle with the wolf-like figures, attacking them by punching and kicking, which seemed to do some form of harm to them. As the wolves charged at him, he jumped, landing a hit on multiple of them, before multiple tubes would then form, which interestingly enough, harmed some of the wolves before filling with red and blue liquid, similar to the RabbitTank Snap Ride Builder, forming the Drill Crusher.

[DRILL CRUSHER!]

Interesting. That's never happened before. Sento made a mental note of that, before he changed the Drill Crusher into gun mode, firing away at the wolves. As the bullets clashed with the creatures, they'd be push back, signalling to Sento that it did some for good damage to them. However, apparently, it wasn't enough, as he'd be scratched by the claws of the wolves, which were definitely stronger than the normal.

As he readied the Drill Crusher, changing it into Blade Mode again, he then checked the FullBottle Holder on his belt, for any other useful FullBottles that he could use. Interestingly enough, he eyed the Harinezumi and Lion FullBottles on the Holder, as if waiting to be used. Grinning slightly as his sudden advantage, he then grabbed the Harinezumi FullBottle, shoving it into the FullBottle slot on the Drill Crusher, the emblem of a white hedgehog appearing for a few seconds, before the blade would begin spinning at a fast speed.

[READY, GO! HARINEZUMI! VORTEX BREAK!]

As he slashed away at the creatures, he'd make sure to do as much damage as possible; fearing that he'd attract any more of the weird wolf creatures. And as he finished slashing, multiple white spikes would protrude from the wolf-like creatures, as they fell to the ground, beginning to fade into oblivion, surprising Sento. Deciding that their essence was worth taking, Sento looked for an EmptyBottle, before noticing two more on his holder, catching his eye. Taking one out, he'd twist the cap open before the essence of the creatures would be absorbed into the Bottle, as it changed into a blue SmashBottle.

What was also interesting was the fact that another EmptyBottle's cap was already open as well, as it absorbed a more darkened essence from the same creatures, turning into a black SmashBottle. Sento had to admit to himself, he was curious, and scared of the Bottle, to say the very least. But at least for now, the problem had been settled. As he placed the SmashBottle he was holding back into its slot, he decided to stay in armour in the event that more of them came, even if he didn't want such an event to happen.

As he made his way to the forest, heading in the direction of the tower, he found himself thinking back at the fate that the World of Build was undergoing. Even if he himself had defeated Evolt during that fateful suicide attack, there was no guaranteed method to remove the Skywalls that had formed because of the incomplete Pandora's Box's awakening, or even the Pandora Tower that had appeared due to Evolt being a little piece of shit and activating the Pandora's Box's full potential. That was even if Evolt had been truly defeated during his attack. And even if so, there was still the other issue; of Evolt's race, planet destroyers who had the power beyond anything imaginable. Or so was what Vernage had said.

Kazumi, walking towards Misora, asked the entity currently possessing her, Vernage, "Hey. Just who the hell is Evolto anyways?" "A lifeform from a world that this planet has yet to discover. A single member of Evolto's race was enough to destroy our planet." The three Riders were in shock at how strong Evolto truly was. "I was the only one left, and fought him, prepared to die. I damaged the Evol-Driver, and separated his body from his soul...so he used the box to store his own energy." The three Riders would stare at the Pandora's Box, with Gentoku then muttering, "Then Pandora's Box was Evolto's all along." Vernage would mutter one last sentence before stopping her possession of Misora. "Evolto must not be allowed to gain his final form."

With how strong Evolt actually was, Sento feared of the possibility that somebody from the same species of Evolt would come to Earth to finish the job that he had started. And it might even be somebody stronger than him, somebody Sento knew all of the Riders, hell, even Vernage, couldn't even stand a chance of facing against. He just clung onto the hope that he could at least find his way home as fast as possible, if he even was in the homeworld to begin with, and potentially regroup with them.

But even if Evolt's species wasn't intent on returning to Earth to finish the job, there was still the issue that Seito had still taken over Hokuto, and was hell-bent on uniting Japan in the most twisted way possible. For one, there was Juzaburo Nanba himself, dude who is currently guising as the Prime Minister of Seito, and head behind Nanba Industries. If anything, he could easily send out orders to either make more Guardians, or stronger Guardians. Then, there were the Washio brothers; wielders of the Remocon Bros. and Engine Bros. powers, and subsequently the Hell Bros. powers (even if the Riders were mostly stronger than them); but worst of all, there was Nariaki Utsumi himself, the ultimate wild card in the system. The creator of the Nebulasteam Gun, modified from the Kaiser System, and creator of Grease and Rogue's Sclash Drivers. There was no telling of what he could actually do; hell, he could have actually managed to recreate the Evol-Driver itself, or even worse, actually use one. He was really hoping that the three Riders could handle Seito's forces.

But now, having been deep in discussion, he found himself facing the said tower that he had spotted only in the distance mere minutes ago, which somewhat surprised him. And for another, he was surprised at how short the journey it was; maybe it was closer than he first expected, perhaps? It also wasn't just a tower, it felt like an entire academy! Then, he noticed something that caught his eye.

Two individuals approached him, as he slowly took out the two Bottles from their respective Driver slots, causing Sento to de-transform as he simply observed them. The male individual seemed to be wearing an odd shade of green, with some round spectacles to boot, and seemed to be holding a mug of what was either hot chocolate, or coffee. The female individual seemed to have what looked to be a weird device that resembled a phone, but wasn't a phone by Earth standards. And as Sento finished de-transforming, he could only mutter one phrase, "Who are you two?"
