As Lauren and Blake were exiting the armory, they both had failed to notice the immense precautions the UFE facility they were on had undertaken to prevent their escape. Every hallway the duo went down ended with a large black door, forcing them to go down a certain path. "This is smart", Lauren remarked, "They're forcing us outside the main entrance". Blake looked confused and said, "Isn't that a bit counterintuitive?" Lauren remained quiet as the two Riders entered another hallway, peeking after every corner they encountered. The hallways of the UFE base were nothing spectacular, having no decorations and a constant steel-grey color. Each hall had at least two doors on each of its sides that led to other rooms. Unfortunately, just as Blake and Lauren were about to enter the next hallway, two giant black doors came crashing down at both ends of the hall. Out of each of the doors in the hallway came 4 squads of Riotroopers, each squad comprised of 5 troopers. Blake and Lauren now stood back-to-back in the middle of the hallway, both knowing that the only way out of this was to fight these trained soldiers. "Hey Blake, I think it's time you show these punks some dragon power", said Lauren. Blake shook his head, "You know, I would love to help, but…". Lauren's face grew annoyed, "But what?", said she. "I may have sent it outside for me to call upon it later and, from where we are standing, there are no windows. I think this one is all on you". A slight chuckle escaped from the young woman's mouth as she pulled out her green Gamer Driver and attached it to her waist. Before she could make another movement, a Riotrooper lunged forward with his Axel Ray Gun (in blade mode), which Lauren quickly countered by moving to the side, grabbing his wrist, and kicking him in the stomach. Lauren then revealed her Hurricane Ninja Gashat and pressed the button to the right of the gashat's cartridge, which elicited the announcement, "HURRICANE NINJA!" The young woman then slammed the gashat into the first port of the Gamer Driver, causing the voice of the driver to say, "GASHAT!" Finally, Lauren pulled on the Actuation Lever and begun the transformation.
GACHAN! LEVEL UP! MAKIMAKI! TATSUMAKI! HURRICANE NINJA!
Once he heard the transformation conclude, Blake turned around to get a good look at Kamen Rider Fuma. Where the young woman once stood is now an armored figure with spikey white hair on the helmet, piercing yellow-orange eyes, dark navy pants and shoulder pads, a white tunic with hexagon patterns, and black gloves and boots with orange trimming. "Whoa", Blake remarked, forgetting momentarily the amount of danger the two were in. Fuma made a run for the first Riotrooper in front of her, grabbed the poor soul and gave him a high kick in the stomach. The impact of the kick sent the soldier directly to the ceiling and damaged the lighting system, so now only half of the lights were on in the hallway. "This is what I'm talking about", Fuma stated with glee as she turned to face Blake. The armor-less Rider attempted to be of help as his fist contacted a trooper's chest-plate; however, the attack was futile as Blake ended up doing more damage to his own hand. Although Blake could not see it, Fuma rolled her eyes in annoyance as she now saw how utterly useless the young man was in this situation; that is until she had an idea. In a flash of quick speed and acrobatics, Kamen Rider Fuma made it right next to Blake and said, "I have an idea, do you trust me?" The young man responded, "Do I have a choice?" Fuma cocked her head, being annoyed once again, and touched the center of Blake's chest. After approximately two seconds, blue pixels, not dissimilar from the ones Lauren had when transforming into Fuma, quickly encompassed the man as another type of armor began to generate around his body. Once the blue pixels ceased, Blake assumed that his new metamorphosis had ended and looked down at his new form. The suit Blake was now wearing was identical to that of Kamen Rider Fuma's albeit having a helmet with only one big orange-brown eye in the center and a black bandana on the very top. Blake was very confused and asked, "Uh, what did you do to me?" Fuma responded, "I helped you out, you're welcome. Now, I need you to fire a shuriken at that light above us". Not wanting to waste any more time (but still confused), Blake began padding himself down to look for a shuriken but couldn't find one. "Hey Lauren", Blake began, "I think you gave me the armor without the shuriken". "No, you idiot! It is an energy-based shuriken, so just think of shooting it at the light and it should work", Fuma retorted. The man looked at his hands and rubbed his right palm on top of his left palm which, to his surprise, sent out a light-blue digital shuriken towards the Riotrooper in front of him. The Riotrooper soon found himself flying backwards into 3 other troopers. "Whoa", said Blake with glee, "This is awesome!" Still irritated, the ninja-based Kamen Rider replied, "Blake! The light now!" Blake looked up, rubbed his palms together, and sent out a shuriken toward the light. The light quickly went out as the glass holding the electricity shattered and fell to the floor. Now in pitch black darkness, Blake could only rely on his sense of hearing, which was picking up grunts and thumps coming from all different directions. Five seconds after the sounds began, they suddenly stopped. A red emergency back-up light came on from the ceiling, illuminating the room which now contained the unconscious bodies of twenty Riotroopers. Blake looked up from the ground to see a standing Fuma breathing heavily. "Are you alright?", Blake inquired. Kamen Rider Fuma merely signaled with her index finger for Blake to come closer, to which he did. The female Rider then put her hand against Blake's chest, causing the armor around him to turn back into blue pixels and flow into Fuma. The breathing of Fuma's immediately stabilized and she remarked, "That's better", as she walked to the large door obstructing the duo's path. "So…", Blake began, "what exactly was that?" Whilst examining the door, the female Rider responded, "One of the benefits of the Hurricane Ninja Gashat is that I can summon what I call 'Ninja-Players' to assist me when needed. However, since we were in this small, crowded space I couldn't find a could place for them to spawn so I figured I could try to put the armor on you. Thankfully, it worked". Blake's eyes widened with fear and distrust, "What do you mean 'thankfully, it worked'? Are you saying that I was your little lab rat for this experiment?" Kamen Rider Fuma remained silent as she found the bottom edges of the door, put her fingers to it, and lifted. Thanks to the enhanced strength the armor provides, Fuma was able to lift the door just a little over her 5'4" frame which allowed her to peak into the next hallway. Displeased with what she saw, Fuma lowered the door back down and cursed under her breath. "What's wrong?", Blake inquired. "The hallway past this door has another door just like this one on the end of it. I think the best course of action would be to go through one of these doors the troopers came out of and hope for the best", stated the Kamen Rider. Blake thought for a moment and said, "Alright. Suit me up". Fuma shook her head and stated, "No need", as she snapped her gloved fingers, summoning three Ninja-Players next to her. "They can handle the combat for us".
By sprinting down the unobstructed corridors, both Blake and Kamen Rider Fuma were able to make it to the last hallway before the main exit in three minutes. Any conflict the duo encountered was dealt with by Fuma's Ninja-Players, which merged back with her once each skirmish was resolved. Now at full strength, Fuma reached for the dual kodachi blades that were attached to her back and walked slowly toward the exit with Blake following close behind. "The minute we get outside, summon your Cross-Z Dragon immediately", Fuma commanded. Blake responded, "I was going to do that anyway". Upon going through the exit door, the two were surprised to find that no one was outside waiting for them. And, to her displeasure, Fuma noted that the sirens were off; in fact, they had been off for the past two minutes. "Blake!", Fuma yelled loudly, "Transform no…!" Cut off by a quick slash to the back, Fuma launched forward landing face-first on the asphalt-covered ground. Turning his head to look at his comrade, Blake mistakenly created an opening for another Kamen Rider to attack him; or, in this case, another Kamen Rider's dragon. Dragreder, Kamen Rider Ryuki's red mechanical Japanese dragon, launched a barrage of fire from its mouth in Blake's vicinity. Feeling the heat of the fire, Blake did the most sensible thing every child learns when caught on fire: stop, drop, and roll. As both Blake and Fuma regained their footing to look at their attackers, Ryuki states, "It's over you two. I do not think it is in any of your best interests to fight back, because if you do, you will lose". The announcement voice of the ZECT Riders yells, "CLOCK OVER!", as Kamen Rider Sasword returns to perceivable levels of speed and stands next to Ryuki. Fuma, still recuperating from the first attack, slowly turns to face the red-clad Kamen Rider and retorts, "Dan, look at yourself. You were never this imposing or threatening years ago. What happened to you? Do you think Annie, your fiancée, would approve of your actions?" Blake's eyes widen, shocked by Fuma's taunt, and watch as Ryuki's fist clenches in a futile attempt to control his anger. Sasword, wanting to avoid any form of heavy conflict, puts his violet-clad violet hand on Ryuki's right shoulder and says, "She's just trying to get to you Dan, we can avoid bloodshed if we all remain calm". Ryuki pushes the scorpion-based ZECT Rider's hand off his shoulder and pulls out the Sword Vent card from his Advent Deck. Kamen Rider Ryuki takes the Advent Card, slides it into the Drag Visor located on his left forearm, and pulls up on the visor which intiates the effect as well as the voice, "SWORD VENT!". In an instant, Dragreder's tail removes itself from his body and flies over to Ryuki's right hand. The contract monster then flies into Mirror World, awaiting the next command from his master. The "Dragon Knight" turns his head toward Sasword and orders, "Immobilize Fuma, I'll deal with Cross-Z". With that command, the violet Rider begins walking toward Fuma and holds his sword in a position that grants him a higher defense than offence. "Stay down Lauren", Sasword recommends, "I don't want anyone to get hurt". Fuma lets out a chuckle and retorts, "It's a little too late for that Shawn (not to be confused with Sean/Kamen Rider OOO)". The ninja-based Rider performs a backflip, landing successfully behind Sasword, and, using her dual kodachi blades, slices the back of his armor. "Hurts, doesn't it!", Fuma yells to Sasword as he now falls to the ground face-first. Meanwhile, Blake, seeing Ryuki charging toward him, holds his hand up to the sky and screams, "Cross-Z Dragon, I need you now!" Almost immediately, the small mechanical blue dragon that Blake uses to transform flies down and lands in the young man's palm. Without a moment to lose, Blake inserts the Dragon Fullbottle into the slot on the dragon, triggering the "WAKE UP!" announcement. Blake loads the dragon into his Build Driver and turns the lever.
CROSS-Z DRAGON! ARE YOU READY? WAKE UP BURNING! GET CROSS-Z DRAGON! YEAH!
Now armed and ready for battle, Kamen Rider Cross-Z summons his Beat Closer and charges toward Ryuki, resulting in the clashing of their blades. "I guess I should probably tell you", Cross-Z remarks, "I resign from the UFE". Ryuki laughes and responds, "Oh you idiotic fool, you will wish that it was that simple", as the red-clad Rider thrusts his Drag Saber up, causing Cross-Z's arms to momentarily follow and thereby create an opening. With no mercy, Kamen Rider Ryuki slashes Cross-Z across his chest and kicks him in the stomach, sending the blue dragon-based Rider back 10 feet. Cross-Z turns to try and see if Fuma is free to help him, but he instead witnesses an intense battle filled with strategic timing and fluid combat that he could only dream of mastering. Unfortunately for Fuma, her water-like movements were cut short as what appeared to be a medal-shaped energy projectile hit her right side, knocking her down. Out of the shadows came out Kamen Rider Birth as he then put a Cell Medal into his Birth Driver and turned the knob on it, generating a popping sound. The "SHOVEL ARM" activation sound occurs as a large mechanical grey (with some orange markings) claw-like shovel appears on Birth's left forearm and subsequent hand. "Good shot, Quintavius!", Sasword yells as Birth runs over to Ryuki and Cross-Z and grabs the latter Kamen Rider with his Shovel Arm. "Shawn!", Ryuki shouts, "use your Rider Slash on Lauren now!" Before Sasword could touch his Zecter, a loud explosion erupted from one of the walls about fifty feet away from Ryuki. Through the smoke a figure could be seen running towards them, and the identity of this figure was soon deduced as a loud voice announced:
ARE YOU READY? TENKUU NO ABARENBOU! HAWKGATLING! YEAHHH!
In his HawkGatling form, Kamen Rider Build flies over to Birth and kicks him on the head, releasing Cross-Z from his grasp and knocking Birth down. Build then travels to Sasword and lands on top of his shoulders, causing the purple-clad Rider to collapse from the weight. Leaping off Sasword and landing beside Fuma, Build helps her up and asks, "I'm guessing by the amount of chaos and alarms you and Blake both triggered that you are on our side?" "Something like that", Fuma retorts, "and thanks for the assist". Ryuki, now screaming with pure anger and frustration, announces, "You are all finished!", and pulls out a card from his Advent Deck. Placing it in the Drag Visor, Ryuki quickly activates it which triggers the loud declaration, "STRIKE VENT!", from the card reader. "Oh damn", Cross-Z remarks as he now runs over to Kamen Riders Build and Fuma. The trio nervously watch as Dragreder comes out of Mirror World and a copy of his head, called the Drag Claw, lands on Ryuki's left hand. "Uh guys?", Cross-Z inquires anxiously, "Got any ideas?" Build rests his left hand on Cross-Z's right shoulder and answers, "Your finisher might be strong enough to counteract his Strike Vent…hopefully". "Hopefully? What do you mean hopefully?", Cross-Z asks, clearly panicked. "You got this", Fuma states as she walks over to Cross-Z's left hand, grabs it, and places it on the lever of his Build Driver. Eight feet away, Ryuki pulls his right arm back as both he and Dragreder both charge their attack for maximum firepower. After turning the crank five times, the Build Driver on Cross-Z's waste chants, "READY, GO!", and a giant blue energy-based dragon appears behind the Rider. In response, Ryuki quickly thrusts the Drag Claw, causing both he and Dragreder unleash an intense amount of fire towards the traitorous trio standing ahead of them. Before the fire could reach he, Build, and Fuma, Cross-Z leaps into the air and the blue and orange Chinese dragon behind him blasts fire that surrounds him; all the while the "DRAGONIC FINISH!" sound occurs in the background. This combination allows Cross-Z to fly forward, cut through the blazing inferno coming towards his comrades, and finally land a kick on Kamen Rider Ryuki.
Well, at least, Cross-Z thought he landed his Rider Kick on Ryuki. As the smoke cleared, both Build and Fuma could see their friend on the ground and Kamen Rider OOO between him and Ryuki. In fact, the amount of energy needed to generate the attack was so great that Cross-Z reverted back into Blake. Upon closer inspection, Build could see that the metals Kamen Rider OOO had active were the Kuwagata, Kame, and Cheetah medals; as seen by the green stag beetle head, brown hardened center, and bright yellow legs. Ryuki chuckled, "Nice timing Sean". "Right?", OOO responded with glee, moving his shell-like arms to the side of his body; as he had used them to form an energy shield to deflect Cross-Z's attack. Build nervously turned to Fuma and inquired, "Alright, got any more ideas?" Fuma only shrugged in response and took out her blades. "I wouldn't do that if I were you", a voice behind Build and Fuma said. As the duo turned, they saw Kamen Rider Gaim and at least a dozen squads of Kurokage Troopers. Then, Kamen Rider Zangetsu landed beside Gaim, having leaped from the rooftop of the building. Instead of her typical Melon Arms, Zangetsu had instead opted for the use of the strawberry-based Ichigo Arms. Quickly, the Kurokage Troopers began surrounding Build, Fuma, and Blake. "I think this is obvious, but in case you two are too stupid to see that you're outnumbered I suggest you take off your armors now", proclaimed Gaim. Build shifted his head toward Fuma and whispered, "How fast can you get to Blake if I were to create a distraction?" Fuma replied, "Very fast and I can even get him out of here". Although confused, Build put his trust in Fuma and began quickly spinning the barrel of his HawkGatlinger. "10, 20, 30, 40…", were being shouted by the weapon as the Hawk-and-gun armored Rider leaped off the ground and began gaining height. "Get back!", Gaim and Ryuki yelled simultaneously as the diameter of Build's attack grew and grew. "50, 60, 70…", the numbers increasing doubled the speed of those running away from the potential blast radius. All except for Kamen Rider Fuma who had run over to Blake, grabbed him, and pressed a button on her Game Driver that triggered the announcement, "STAGE SELECT". "80, 90, 100! FULL BULLET!", was screamed from the gun as Build looked down to find both Fuma and Blake gone. With a smile behind the helmet, Build pulled the trigger of the HawkGatlinger which pulverized the sky and ground with astounding gunpower. Left and right, Kamen Riders were trying to dodge the truly excessive yet awesome amount of gunfire. One example is Kamen Rider Sasword, who tried to activate his Clock Up but failed has 10 bullets lit up across his back; if he were not in his armor, he would have surely died. Once all 100 bullets had finished being deployed, Build attempted to gain more distance so that he could escape, but that would fail spectacularly. During the crossfire, Kamen Riders OOO and Birth had formulated a plan: OOO would transform into Latorartar form and Birth would use his Cutter Wings to fly OOO to Build for him to land on his back and shred the wings with his claws. And once the firing ceased, Kamen Riders OOO and Birth did just that. Now, with his wings from the Taka Fullbottle severely damaged, Build began rapidly descending toward the ground and landed on his back. "Ow", Build uttered as he looked around himself to see that he was, indeed, surrounded. More and more Riders began appearing around him, such as Ghost, Specter, Gatack, and Zolda. "Zolda!", Ryuki commanded, "Blast him to Kingdom Come!" Kamen Rider Zolda nodded in response and signaled for the other Riders to back away. Feeling hopeless and full of despair, Build uttered a prayer that was too quiet to be heard as he watched the green-buffalo-based Rider load an advent card into his gun-like Magna Visor. "SHOOT VENT!", was announced as two large cannons mounted on top of his shoulders and were fired. However, the world was not finished with Kamen Rider Build as blue pixels began forming in front of him mere seconds before the fiery projectiles hit him. As the pixels cleared and the blast was absorbed, Build's eyes focused on what protected him. What he saw was Fuma and covering her in a protective embrace was Kamen Rider Kabuto in his masked form.
