It's a sunny day in Tokyo, and sitting at a café outside table are the DenLiner crew; composed of the Imagins Momotaros, Urataros, Kintaros, and Ryutaros; all sitting back and relaxing, Kintaros more so since he's literally snoring. "Ah, a perfect day for a day-off. We haven't had one of these in a while." Momotaros sighed as he takes a sip of his coffee. "Uh, gross. Needs whatever Naomi puts in ours."
"Officially, anyway." Urataros said as he reads today's newspaper. "We're always on-duty most of the time, but nothing happens for years on end. Because of that, we lay about waiting for the next thing to happen. Owner gave us this off-day, but it feels just like any other working day."
"Hmmm…" Momotaros taps his fingers on the table. "Yeah, you're right. It's been awfully quiet for us lately. The last big thing we were involved in was when we accidentally brought a small girl to the eighties."
"Don't forget that time you mistook that one man for Kai and beat him up." Urataros pointed.
"Oi, you're leaving out half the picture. That wasn't just some guy!" Momotaros argued.
Then Ryutaros butts in. "In case you don't know what they're talking about, check out 'Who's That Gai' for the full story!" he told us before Momotaros pushes him out of the way.
"Yeah, yeah, we get it." Momotaros grumbled. "Now that I think about it, yeah, it's been really boring lately. We need some spice in our life."
"Senpai… we talked about this last time. Don't go around causing problems for you to solve!" Urataros reprimanded him.
"I know! I know! I still want something exciting to happen! I can't wait another day for the next crossover!"
Then, the ground beneath them quakes as mechanical horn's roar fill the air. "Eh?! What? What?! What's happening?!" Ryutaros panicked as he jumps out of his chair.
"Oh, here we go again!" Momotaros grumbled as a dark portal manifest in the sky, unleashing a dark steam train winding across the sky like a snake before splitting apart and forming into a dinosaur-shaped mecha, then a massive dinosaur monster wearing a yellow diesel train helmet.
"Ah, this looks like trouble!" Urataros pointed to the monsters. "Let's go after them!"
"No need. Look again." Momotaros groaned as he points ahead.
Urataros and Ryutaros looks at the road beside them to see a convoy of glittering vehicles driving down the road; a sparkling ruby fire truck, a brilliant sapphire jet, a shimmering emerald car, a pretty morganite helicopter, and a glimmering topaz bucket excavator. As fast as the speed of light, these vehicles climb atop the fire truck and combine into a massive shining robot, crowned with a dazzling gem crown, armed with a jet-sword. "Ready! Kiramazin!" a chorus of voices shouted.
"Ah, it's Mashin Sentai Kiramager!" Urataros pointed to the mecha slashing the monsters, seemingly with no resistance nor difficulty from its opponents.
"Grah! Of course, it's Saturday! That means the Sentai get to trash the city like it's nobody's business!" Momotaros complained. "Oh, if only I could go up there and fight those monsters train-on-train!"
"Oh, you're so excitable. It's time for the new bloods to have a go, don't you think?" Urataros said.
"Everyone, look!" Ryutaros pointed to the sky where a white bullet train flying through the air.
"They got a bullet train like us!" Ryutaros giddily skips in place.
The train shines blue rays from its headlights onto the dark dinosaur mecha to forcibly disassemble, then reassemble it into a humanoid robot for the train to dock into as the chest and head, now armed with a chomping dinosaur hand and a chainsaw arm. "Ready! King Express!"
"Wasn't it evil just now?" Ryutaros commented.
"Ah! They got another one! Dammit, why do they get all the fun?! What do they have that I don't?!" Momotaros growled.
"A giant robo, for one." Ryutaros suggested.
"Two, really." Urataros added before being pushed aside by Momotaros.
"Of course! A giant robo! We need one of those!" Momotaros realized.
"Senpai, we're Kamen Riders. We don't do giant robos. That's what the Sentai are for." Urataros reminded him.
"That may be so, but we're already not like the other Kamen Riders. We have the DenLiner, after all! We're one of the first to break the mould!" Momotaros insisted. "Watch out, world, for today is the day we awaken our own giant robot: Kamen RiderOh! Hahaha!" he shouts at the top of his lungs before looking at King Express wailing its chainsaw on the diesel train monster.
"Senpai, I think you might be going a little overboard with—"
"It'll be even cooler than yours, Kiramagers! It'll be bigger, flashier, and better! Mark my words!"
As the two mecha back away towards the cafe, the diesel train monster spews boiling diesel at them, flooding the street with its caustic fluids. "Aaah! Run away!" Momotaros screamed as the cafe explodes when the oil splashes down, causing the crew to leap away from the ensuing explosion.
When Ryutaros rolls along the pavement, the sleeping Kintaros incidentally lands atop him like bricks. "Someone, help get the bear off me!" Ryutaros called as he lies buried under the sleeping Kintaros. "Oh, for crying out loud!"
"Crying…?" Kintaros gets up and choke-holds Ryutaros. "If there's anything to make someone cry, it's my strength!" he declares as Ryutaros tries to break free.
"Kiramaizin Duston!" With a massive lapis vacuum cleaner, Kiramazin sucks up the rest of the oil, then with even more suction power, removes the train helmet, revealing a fish-like head on the monster.
"Kiramai Dynamic!"
"King Express Burn Plaster!"
Kiramazin sends down three shining slashes from its sword, while King Express produces a number of boomerangs from its cockpit towards the monster. The powerful attacks landing on the creature was too much for it, and as a result it crackles with dark energy before falling down and exploding, giving an epic backdrop for the machines to pose with their blades.
In the DenLiner's diner car, Momotaros confidently enters the room as his teammates follow not far behind. "Senpai, do you even know where to start making a giant robo? We couldn't possibly have the resources to make one." Urataros asked as he trails behind Momotaros.
"We could ask Stationmaster for extra DenLiners and make one like ToQ-Oh." Kintaros suggested.
"It's all made of trains!" Ryutaros added.
"Nah, I don't think he'll waste them on us." Momotaros disagreed. "And we're not making giant robo parts, we're finding them!"
"Finding?" Urataros cocks his head in confusion.
"There are Kamen Riders that have been made into giant robo before!" Momotaros pulls down a projector screen. On the screen, images of various Kamen Riders fighting side-by-side with Super Sentai teams. "In almost every crossover, Kamen Riders and Super Sentai teamed up in some way, whether on the ground or in giant robo!" Momotaros points at the screen with a presentation baton, then to Kintaros and Ryutaros.
"Uh…" Kintaros scratches his head.
"You two got a point about ToQ-Oh. This very DenLiner joined with them in the war between Heisei and Showa Kamen Riders as ToQ-Oh DenLiner!" Momotaros points to a video of the DenLiner becoming the chest portion of a train-based mecha with Kamen Rider Den-O's head.
"Don't you remember what happened next, senpai? Kyoryu Red appeared suddenly with his own Gabutyra transforming into a train." Urataros added when Momotaros looks back at the screen.
"Dinosaur arriving now!" announces a station announcer as almost immediately after the DenLiner joins the formation, a red T. Rex-headed train knocks it out and takes its place, sprouting a robot's head with a silver face and a spiked helmet.
Then the camera pans down to the mecha's feet to show two DenLiners replace its legs. "ToQ-Oh Kyoryuzin! Complete!" a full view of the chaotic combination zooms out before zooming into the legs. "Featuring the DenLiner!"
"Oi, why am I the legs?!" within the clip, Kamen Rider Den-O complained.
"Don't remind me. I'm still upset about that." Momotaros grumbled.
"Where'd the other one come from, anyway? We don't have two DenLiners, do we?" Ryutaros wondered.
"It doesn't look like the New DenLiner, either." Kintaros scratches his helmet.
"Thanks to that experience, we have the first part of Kamen RiderOh: the body and head!" Momotaros pastes a cut-out of a humanoid silhouette onto the screen, followed by a cut-out of the transformed DenLiner with Kamen Rider Den-O's head on top of it. "It's the perfect start!"
"Did someone say something about a giant robo?" Entering the car just then is Owner, the owner of the DenLiner and the crew's boss, spinning his cane as he struts towards them. "Are you referring to our collaboration with Rainbow Line's ToQgers some years ago?"
"Yeah, we're gonna do that again, but with Kamen Riders only! And I'm gonna be the body this time!" Momotaros answered. "Owner, do you have anything to help with that? Some gadget that can transform the DenLiner again?"
"Owner, surely you won't agree to his crazy plan?" Urataros pleaded to Owner before his cane is put between his eyes and is nudged away.
"Did you think it was just your power alone that allowed you to combine with ToQ-oh in the first place?" Owner chuckled as he wiggles his hand into his jacket pocket. From his pocket, he presents a model of the DenLiner's main car. "This was a present from the President of the Rainbow Line to me. I didn't think we'd ever need this again, but I understand the prospect of Kamen Riders needing a giant robo in the future."
Momotaros promptly takes the model and bows at Owner gratefully. "Thank you!"
"Why's it so small, though? The ToQgers' train gadgets are longer, aren't they?" Ryutaros commented as he looks closely at the train in Momotaros' hand.
"Don't worry about that. Just do me proud in this little project of yours." Owner smiled.
"Even Owner's in on this? Has the world gone mad?!" Urataros said to himself. "Is this what Hana feels like all the time? For once, I wish she were here to sort things straight."
"Lunch is ready!" entering the car this time is the DenLiner's waitress Naomi, carrying a tray with four cups of her famous pink-and-blue foaming coffee and a plate of fried rice with a small flag illustrated with the DenLiner stuck in the centre, orbited by sprigs of parsley and octopus sausages.
"Ah, thank you, Naomi. I was getting hungry." Owner sat down at a booth for Naomi to put down the plate before him. With a fist slamming onto the curved end of a spoon, he flips it into the air before catching it and digging a small scoop from his rice to take a bite out of.
"Ah, thank you." Kintaros bowed to Naomi as he takes his cup of coffee, alongside his friends.
"Fresh from the tap, just how you like it." Naomi gave them a happy wink.
"But senpai, surely there aren't that many other Kamen Riders who joined with Super Sentai like this." He turned to Momotaros before taking a sip.
"That's where you're wrong, turtle!" Momotaros takes down the cut-outs and the projector turns on again, displaying a mosaic of mecha clips in action.
In the top left corner of the screen, a bunny-eared robot punches a massive skeletal robot thrice its size with orange rocket arms in Earth's orbit. Beside it is a clip of a red dinosaur-like mecha flying into space with the aid of a massive silver dragon's foot. Beneath the first is a futuristic red car transforming into a robot that sits atop a throne mecha made of various animals and vehicles, armed with a massive sword. The last clip is of ToQ-Oh DenLiner that was already shown before.
"To answer your question, turtle: there are enough Kamen Riders. And I know just where to find them." Momotaros smugly told them. "What say we get some donuts for this coffee, eh?"
At a park, food trucks and food stands are set up to feed the passerbys and park-goers; from burgers to donuts to kebabs, food from all over is served. Casually coming in as is, the DenLiner Crew strut into the scene, or rather just Momotaros dragging along his reluctant companions. "Our first Kamen Rider is Wizard! During the battle against Space Shocker, Kamen Rider Wizard joined his WizarDragon with Zyuden Sentai Kyoryugers' Kyoryuzin to become a Miracle Combination!" Momotaros informed his team.
"So, why are we here at a random park, then?" Urataros asked.
"I'm not complaining. I completely missed lunch!" Kintaros added.
"Soma Haruto, Kamen Rider Wizard, no longer lives at the antique store he once used as his base. From what I heard, he roams about to look for a resting place for his old friend." Momotaros began explaining. "But during this journey, he takes a break for a donut, and wherever there's donuts, he's there."
"You mean Donut Shop Hungry?" Ryutaros asked.
"Precisely! Last I checked, that truck was spotted around this area last week, and should still be here!" Momotaros confirmed as he walks around.
"What does this truck look like?" Urataros asked.
"It's small, pink, and you can't miss it." Momotaros described when they pass one such truck, and back up to stare at it.
"Ah, there!" Ryutaros points at it.
"It doesn't look like he's here, though." Urataros noted.
"We'll see about that." Momotaros then marches to the truck's open counter and dings the bell. "Oi, service here!"
Popping out from under the counter is an older middle-aged woman with rather masculine features contrasting a blonde bob-cut, and an especially large smile. "Hello, welcome to Donut Shop Hungry! May I have your order?"
"Excuse me… ma'am? Sir…?" Momotaros awkwardly greets the manager.
"Oh, call me anything, as long as it's 'beautiful'." The manager flirted.
"Uh, okay, so… have you seen a guy with red pants and weird rings on his hand? Orders a plain sugar donuts?" Momotaros asked.
"Oh, you're talking about my regular, Haruto." The manager realized. "I haven't seen him in a while. It's been about a couple months since I served him a donut."
"Damn! We missed him!" Momotaros growled before feeling a finger tap his shoulder.
"Oi, are you gonna order something or get out of the line?" asked a man's voice from behind.
"Hey, wait your turn! I was gonna order a—" Momotaros furiously turned around to the other guy when he realizes who he's talking to: Soma Haruto himself, dressed in red pants, a red tie-dye shirt, and a black leather jacket.
"Haru-chan, there you are!" the manager beamed at the sight of the young man. "I developed a new flavour! It has ki—"
"Plain sugar, please." Haruto ordered.
The manager sighs. "Oh, okay. One plain sugar donut coming up."
"Actually, make that five." Haruto corrected, looking at the Imagin around him. "I heard you fellows were looking for me?" he raised an eyebrow at them.
Soon after receiving their donuts, the DenLiner Crew and Haruto sit at a plastic table in front of the donut truck. "Thanks for sitting down to talk to us, mister Haruto Soma." Kintaros politely greets him.
"Anything for fellow Kamen Riders." Haruto said as he takes a bite out of his donut. "So, what's this about?"
Momotaros stands from his chair. "We're making a giant robo for Kamen Riders!"
"A giant robo? Isn't that the Super Sentai's thing?" Haruto questioned.
"Senpai's just bored and jealous. He thinks we need our own giant robo to show off." Ryutaros explained.
"We can show those Super Sentai us Kamen Riders can have giant robo and be just as, if not more, cool!" Momotaros said.
"Where do I come in?" Haruto asked.
"Remember when you joined Zyuden Sentai Kyoryuger to destroy Demon King Psycho?" Momotaros recalled.
"I used my Miracle Ring to allow WizarDragon to join their robot, yeah. You saying you want him for your giant robo?" Haruto asked.
"Absolutely! It's clear as day!" Momotaros then slaps on the cut-outs of the humanoid base and the DenLiner on the table towards Haruto. "Your WizarDragon already transforms into a giant foot, so that's what it'll be!" Momotaros then slaps on a cut-out of WizarDragon in Strike Phase onto the silhouette's right leg. "Whaddya think? You in?"
"Not gonna happen." Haruto refused before taking another bite.
"Eeeh?! Why not?!" Momotaros screeched.
"Not like I could if I wanted to. I don't have the Miracle Ring anymore." Haruto explained.
"How come? Aren't you careful with your Wizard Rings?" Kintaros asked.
"I just don't have it anymore. It disappeared as soon as the battle was over." Haruto answered.
"Well, then this was a bust." Ryutaros sighed.
"C'mon, you gotta have it somewhere! Where'd you get it, anyway?" Momotaros asked Haruto.
"I don't know. Some Wizard Rings just come and go. It happens." Haruto shrugs. Just as he casually eats his donut, a white orb flashes in the middle of the table before them. When the flash recedes, a ring studded with a large aqua gem with a question-mark-shaped carving appears before them.
"Like that?" Ryutaros asked as he points to it.
Haruto puts his fingers to the side of his head. "It's WizarDragon. He said he's bored and is intrigued by your idea." Haruto informed them.
"So you are in, then?" Momotaros asked Haruto.
"I guess. Gives me something to do before the next battle." Haruto shrugged.
"Alright! That's one foot down! Now for the next!" Momotaros pumps his fist in the air. "We'll have our people call your people, 'kay?" he told Haruto.
"Yeah, sure." Haruto shrugs as he takes the Miracle Ring.
"C'mon, to the next Kamen Rider!" Momotaros hurried his companions as he drags them away.
"Wait! I haven't had my donut!" Ryutaros whines as Momotaros rapidly drags him away from the table.
Haruto watches this strange scene before scooping the uneaten donuts and silently eating by himself. "Hm. Did they change the recipe?"
At the Tokyo Metropolitan Police headquarters, the diligent Detective Tomari Shinnosuke is sitting in his office, talking to a man wearing a cowboy hat and a brown leather jacket. "Don't worry, sir. We'll put up these flyers and find your friend." He assures the man when he hears a knock at the door.
Coming into the room is a slightly older detective, about a decade or so older than Shinnosuke. "Shinnosuke, there's some people here to see you."
"Detective Suzuki, hello. Sorry, I'm busy with someone now." Shinnosuke greets the older detective.
"Unfortunately, but they're not the waiting type." Detective Suzuki told them when the DenLiner Crew appear, with Momotaros jumping into his signature pose.
"I have arrived!" Momotaros announces himself.
"It's you!" Shinnosuke said in surprise when the man he was speaking to stands up.
"Thank you for all your help." The cowboy bows before the detective before walking to the door with his head lowered, hiding his face with his cowboy hat.
"You didn't give me your contact information. How can I call you once I find your friend?" Shinnosuke told the man as Momotaros watches.
"The world's round. We'll see each other eventually." The man told Shinnosuke before putting a strangely-shaped harmonica to his mouth and passes by Momotaros.
"Hey, wait a minute! Aren't you…" Momotaros points at the man when he's interrupted by a slow, mysterious tune played by the man as he walks down the hallway.
"Didn't expect to see him again so soon." Kintaros noted.
"Ahem." Shinnosuke drew their attention.
"I'll leave you to it." Detective Suzuki bows to the DenLiner Crew.
"No probs, Kazu-chan!" Momotaros suddenly clutches the older detective in his arm and gives him a noogie before releasing him.
"Don't cause any trouble, alright?" Detective Suzuki smiles before walking away.
"Come in, take a seat." Shinnosuke calls to the Imagin before they sit down on chairs around the room with Momotaros sitting directly in front of the detective.
"Detective Shinnosuke Tomari, Kamen Rider Drive. We meet at last." Momotaros greeted him. "Momotaros, Kamen Rider Den-O." he extends his hand for a handshake.
"Nice to meet you, Momotaros." Shinnosuke shakes his hand. "So, what is it that Detective Shinnosuke Tomari can help you with? An incident that needs another pair of eyes? Consultation on one of your own cases?" he asked Momotaros.
"We don't need Detective Tomari Shinnosuke, we need Kamen Rider Drive! We're making our own Kamen Rider giant robo!" Momotaros explained to Shinnosuke.
"Giant robo? Isn't that—"
"The Super Sentai's thing, I know, I know. But won't it be cool if us Kamen Riders had our own giant robo?" Momotaros continues his sentence.
"And you're seeing me because of that one time I teamed-up with Shuriken Sentai Ninninger?" Shinnosuke asked.
"Precisely!" Momotaros pointed.
"How'd you know about that?" Shinnosuke asked.
"Tubby told us." Momotaros answered.
"Tubby?" Shinnosuke raised an eyebrow.
"It's what senpai calls Deneb." Urataros explained.
"Here's what I'm thinking." Momotaros slams the cut-outs on the desk, arranging the DenLiner on the chest and WizarDragon on the right leg. "I know your formation was the chest, but maybe we can rework it to become the left leg somehow." Momotaros then places a cut-out of the Tridoron on the figure's left leg. "How does that sound?"
"I'm sorry, but no can do. My days as Kamen Rider Drive are over." Shinnosuke refused.
"Aw, why not?!" Momotaros growled.
"Even if I wanted to, and I kinda do, I can't. Belt-san locked himself and the Tridoron deep underground, and I don't have that shuriken the Ninningers' grandfather gave me. It was erased when Shocker's robot was destroyed and the timeline was restored." Shinnosuke explained.
"Aw, c'mon! There's gotta be a way for you to join in!" Momotaros insisted.
"I'm sorry, but my hands are tied. Belt-san is only for emergencies, and you're basically doing this for indulgence. Plus, even if I could transform into Drive again, I don't know where to find the Ninningers to make another shuriken for me." Shinnosuke refused.
"They are ninjas, after all. They're supposed to be hard to find." Kintaros nodded in agreement.
"Even though they call themselves the 'shinobi who don't hide'." Ryutaros added.
"You'll have to find another Kamen Rider for your foot. If it helps, I wish you luck in this quest." Shinnosuke concluded.
"Bah!" Momotaros slams his hands on the desk as he stands up. "Fine! We'll do it without you, but you'll regret it big time!" he points right at Shinnosuke's face angrily. "Everyone, let's go to the next candidate. He should be more than willing to have some fun with us!"
The Imagin get up from their seats and follow Momotaros out the door, and when Urataros was last he turns to Shinnosuke with his hands put together and bows for forgiveness before closing the door behind him. "*SIGH* Back to the grind, then." Shinnosuke sighed as he gets back to work.
Suddenly, the door slams open again, and barging into the office is a young man with wild brown hair, wearing green pants and a white jacket. "Shin-niisan! I have it! I finished the Drive Driver replica!" the man exclaims as he places a bulky silver thing with a circular display screen onto the table.
"Go, stop barging into my office like that during work." Shinnosuke scolded him casually.
"Sorry, sorry, I just thought you should test it out! It's gonna get us closer to bringing back Chase!" Go insisted.
"I'll…" Shinnosuke turns and locks eyes with the device on his table. "…Think about it."
"Great! Give it a test drive and tell me how it goes!" Go smiles as he puts down a small red toy car. "See ya later, bro!" he then leaves as loud as he entered.
Shinnosuke sits there staring at the Drive Driver before reaching turning the red ignition key, activating an insectoid face on the display. "Start Your Engine!" a macho voice welcomes him with perfect English.
Shinnosuke sighs. "I miss you, Belt-san."
At Shin Amanogawa High School, the DenLiner Crew lurk outside as students roam during their break. "Shin Amanogawa High School: this is where we can find Kamen Rider Fourze!" Momotaros told his teammates. "When Yellow Buster was injured in the first Super Hero Taisen, Kamen Rider Fourze took her place in Tokumei Sentai Go-Busters' Go-BusterOh, powering it up with his Super Rocket Astroswitch to destroy Demon King Psycho! He'll be great for the arms!"
"Don't we need an appointment to see a teacher?" Ryutaros asked Momotaros.
"If we hang around too long, someone will report us to the authorities." Kintaros warns him.
"We're gonna go in there, find that yanki, and get him to give us those rocket arms!" Momotaros screamed before running through the gates, passing by a spooked group of students.
"Senpai, wait for us!" Urataros and the others then chase after him.
"Oooi! Kisaragi Gentaro! Where the heck are you?!" Momotaro screamed as he runs through the school corridors.
"Slow down, man!" Ryutaros screamed as he and the others follow not far behind.
"Times like this make me wish us Kamen Riders had each other's numbers." Urataros groaned.
"Yo, Fourze, where are ya?! We'll tear this entire school in half if we need to!"
"You're looking for sensei, eh?" a young man's voice voiced from behind them. They all turn around to see a young man wearing the school's blue blazer.
"Know where he is, kid?" Momotaros asked.
"Sorry, but I won't let the likes of you touch a hair on his head." The young man declares. "Shouriki Shourai!" his clothes explode into shreds as he instantly transforms into a brown pupa monster with eerie human-like eyes.
"Eeeh?! That kid transformed!" Momotaros pointed at the strange creature.
The creature charges at them, and one-by-one the Imagin duck out of the way, but Momotaros was too late as he and the creature crash through the glass and tumble down into the courtyard, and the first to stand is the mutant. "Face the burning justice of Sanagiman!" the creature declares.
"I'm gonna deal with you, then that yanki's next!" Momotaros produces his Momotarosword, then slashes Sanagiman across the chest, but nothing seemed to make him budge.
Sanagiman grabs his blade and swings Momotaros around like a toy before throwing him into a tree. Momotaros immediately sprints towards Sanagiman, and when the creature raises its fists to block, Momotaros turns into sand that blinds Sanagiman. "Ah! I can't see!" Sanagiman winces as he rubs his eyes.
Momotaros rebuilds himself from sand and drives Sanagiman into a wall, furiously punching him into the concrete. "Being indestructible won't stop you from being pummelled, huh? Huh?!"
Sanagiman gives Momotaros a mean glare, and an invisible force throws the Imagin away. "I'm not all brawn, you know? I have psychic powers as well!" Sanagiman declares as his body heats up. "Chouriki Shourai!" his carapace casts off, revealing a slimmer, yet muscular blue humanoid with yellow veins lining his body, wearing nothing but black briefs, bearing compound eyes and red feathery antennae. "Warrior of freedom! Inazuman!"
"Oh, gimme a break!" Momotaros groaned as he weakly picks himself off the ground.
"Now to finish you!" Inazuman roars as electricity surges off his body. He dashes at Momotaros lightning fast, landing crackling punches on every hit, too fast for Momotaros to react in time.
Momotaros' friends arrive at an adjacent corridor in time to witness Inazuman's beatdown on Momotaros. "We have to stop this!" Urataros decided when a girl wearing the school's uniform approaches them.
"Saburo, stop! He's not a monster!" the girl yelled to Inazuman.
"Hm? Who might you be?" Kintaros asked.
"I'm Ohki Miyoko, third year in class A, and member of the Space Kamen Rider Club!"
"Space Kamen Rider Club? Do you know who we are?" Urataros asked her.
"You're the DenLiner Imagin who share the title of Kamen Rider Den-O!" Miyoko answered.
"What is that creature attacking our friend?" Kintaros asked.
"That's Saburo, a member of the Youth League. He doesn't follow a lot of Kamen Rider knowledge, so he doesn't know he's fighting one!" Miyoko answered. "I gotta stop—" she said when a grey blur dashes past.
"Chouriki Inazuma Otoshi!" Inazuman performs a lightning-charged dash towards Momotaros, intending to finish him off, but the grey dash hits his chest with great force, stopping him in place. When the smoke clears, Inazuman looks down to see a young man slightly older than him wearing a smart grey suit, contrasted by a rebellious pompadour. "Sensei!"
"Saburo, is that any way to treat a guest?" the man smiles as he goes to help Momotaros. "Saburo, meet Momotaros: Kamen Rider Den-O. Momotaros, meet Saburo." He introduced them to one another.
"A Kamen Rider?!" Inazuman said in surprise before bowing. "I'm sorry! I didn't know!" he apologizes when Miyoko comes and smacks the back of his head.
"That's why you should come to the club's briefings! You gotta know who's who when meeting Kamen Riders!" she scolded him.
"You… Kisaragi Gentaro…" Momotaros addressed the man weakly.
"Ah, Momotaros. Nice to meet you!" Gentaro greeted him as he gives him a unique handshake: gripping his hand, inverting down, a fist bump, then pounds it up and down. "Consider us frie—"
"We're building a giant robo. Wanna join?" Momotaros asked tiredly.
"Eh? Is this about the time I helped those Go-Buster guys?"
"Yeah. We need some arms. Rocket arms."
"I'm sorry, but I can't."
"Why not?! Did you lock your belt underground, too?!"
"I… threw it in a smelter a couple years ago." Gentaro embarrassingly scratches his neck.
"Are. You. Kidding me?! Is every Kamen Rider throwing away their stuff nowadays?!" Momotaros growled.
"Hey." Gentaro pats his shoulder before handing a small trinket resembling an orange rocket booster. "Take this: the Super Rocket Switch. I'm not sure how you could, but I'm sure it'll help you in your project."
"Fourze…" Momotaros puts his hand on Gentaro's. "Thanks." Then he collapses.
"Senpaaai!" Urataros screamed, seeing his fallen comrade.
Later, the DenLiner Crew and Gentaro enter a barren quarry; Momotaros resting an icepack on his head. "Again, sorry for Saburo! When it comes to protecting the school, he really gets pumped up." Gentaro sincerely apologizes with his hands clasped.
"Alright, alright, just shut up!" Momotaros growled impatiently.
"At least we got this Super Rocket Switch!" Ryutaros shakes the Super Rocket Astroswitch in his hand.
"Also again, thanks for letting me watch you build this giant robo!" Gentaro loudly added.
"Anything for a fellow Taro." Urataros giggled.
"Now we wait for that donut-loving magician, and Kamen RiderOh can finally assemble!" Momotaros excitedly declares.
Then, Haruto emerges from a magic circle riding his MachineWinger. "I got your call. You got everyone?"
"Not all, but enough." Momotaros takes the Super Rocket Switch from Ryutaros.
"Yo, Haruto-kun!" Gentaro waves at Haruto.
"Fourze. How's things? Is Saburo doing okay?" Haruto nodded.
"He's every bit of the hero we thought he'd be." Gentaro smiled.
"As a certain genius would say: shall we start the experiment?" Momotaros swings the Den-O Belt onto his waist.
"Driver On, Please!" Haruto places his right hand on his belt, and with a magic circle, it expands into the WizarDriver.
"From start to finish, this mecha-building will be at its climax!" Momotaros presses the red form switch.
After flicking the hand author to left-handed position, Haruto equips the Flame Ring on his left hand.
"Shabadoobie Touch Henshin!"
"Shabadoobie Touch Henshin!"
"Shabadoobie Touch Henshin!"
"Henshin." Haruto scans the Flame Ring on the Wizardriver and extends his hand outwards.
"Henshin!" Momotaros he swipes his Rider Pass on the SetTouch, triggering it to blink red.
"Flame, Please! Hi-Hi! Hi-Hi-Hi!" the magic circle converges towards Haruto, layering Kamen Rider Wizard's form.
"Sword Form." Silver and red particles burst from the Den-O Belt to form a silver base armour and additional red shoulders and chests, finalizing with a glassy peach sliding down the helmet to split into red eyes.
"So, it's showtime!" Kamen Rider Wizard twirls around and raises his left hand.
"I have arrived!" Kamen Rider Den-O flicks his thumb at himself before performing his signature pose.
"See you in the sky, old-timer." Kamen Rider Wizard said as he equips the Miracle Ring.
"Miracle, Please!" Kamen Rider Wizard scans his Miracle Ring, and a massive magic circle unleashes the screeching Wizardragon. With the MachineWinger, he pops a wheelie to convert it into the Great Full Winger to combine with the beast's wings.
"Oi, it's senpai, to you!" Kamen Rider Den-O growls before the DenLiner picks him up and escalates into the sky.
Flying side-by-side with the DenLiner, Kamen Rider Wizard gives a thumbs-up to Kamen Rider Den-O rides the Machine DenBird on a treadmill control system. "Ore Gattai!" He extends his arm sideways with the DenLiner model in-hand.
The DenLiner flies off its rail, folding the main car onto the second car before turning downwards. The cockpit flips forward, then the caboose separates to leave behind Kamen Rider Den-O's head.
"Switch On!" Kamen Rider Den-O prepares the Super Rocket Switch, but looks at it confused. "How'd I use this thing? Do it plug it somewhere, or…" he fiddles with the device before flicking the booster like a lever.
"Rocket! Super!"
"Rocket On."
The DenLiner's caboose returns and splits into two, forming shoulders and arms that the digitizing Rocket Modules attach onto. Kamen Rider Wizard leaps off Wizardragon into the DenLiner, allowing the dragon to Strike Phase into the mecha's right leg. Falling from the sky, the mech fires its thrusters to break its fall, landing gracefully by its Strike Phase foot. Unfortunately, that's its only foot.
"Where's the other leg?!" Gentaro panicked as he clutches his head.
"Drive-san backed away since he didn't have his Sentai crossover gadget!" Urataros explained.
"We must get to our trains and help Momonoji!" Kintaros suggested before a red dash speed past them.
When the dust settles, they find a sleek, bright red car zooming towards the falling mecha. "The Tridoron! Drive came to help us!" Ryutaros excitedly jumped.
As the Tridoron drives towards the hopping mecha, a red-armoured Kamen Rider with headlight eyes and a tire worn like a sash jumps out of the roof hatch: Kamen Rider Drive. He produces his Handle-Ken and a red shuriken illustrated with his face, placing the shuriken on the steering wheel portion of his sword and spins it.
"Dare ja, dare ja?! Dare, dare ja?! Dare ja, dare ja?! Dare, dare ja?! Tridoron!" With a front flip, the Tridoron transforms into a humanoid robot with a head resembling the Drive Driver, piloted by Kamen Rider Drive on its shoulder.
As Kamen Rider Den-O and Kamen Rider Wizard twist the DenBird's handlebars left and right in a panicked attempt to control the mecha, they look past the red windshields to see OtomoNin Tridoron running towards them. "Is that Drive?" Kamen Rider Wizard wondered.
"Oi, give us a hand! Or maybe a foot!" Kamen Rider Den-O waves. To their surprise, the robot kicks the DenLiner torso out, causing the rest of the components to fly off uncontrollably.
"Not like thaaat!" Kamen Rider Den-O and Kamen Rider Wizard continue panicking as the train tumbles into its default state.
When OtomoNin Tridoron lands, it raises its fist to summon a gigantic green garbage truck that detaches its main cab to allow the waste collector-end to diagonally rotate upwards, and only after do the components converge together.
The DenLiner first unevenly folds itself lengthways and pivots upright by the cockpit, which becomes a left foot. Then, the Wizardragon attaches to the other end of the train to complete the legs as it attaches to the bottom of the waste collector. Thirdly, the new torso deploys metallic white shoulders from which the zipping Rocket Modules grapple onto. Afterwards, OtomoNin Tridoron sits on the waste collector like a throne, controlling the mecha with joysticks. Finally, the Tridoron Shuriken flies out of OtomoNin Tridoron's windshield, then expands to sit atop the head, forming a wide-brimmed helmet with Kamen Rider Drive's mask.
The mecha's interior is a black void where the three component Kamen Riders are teleported inside at the helm of their own controls.
Kamen Rider Den-O remained seated on the DenBird and connecting treadmill system, looking around in confusion at the new environment. "Aw, c'mon, the foot again?!"
Kamen Rider Wizard is standing on an elevated red platform marked with his own insignia, flanked by a black-and-red crest. "Oh, this is familiar."
Between them is Kamen Rider Drive, sat in the controls of a racing rig with the Handle-Ken's wheel. He turns to Kamen Rider Den-O and nods.
"Hey, what's the big idea?! I wanted the body! You're supposed to be a foot!" Kamen Rider Den-O growled at Kamen Rider Drive as he dismounts the DenBird. As he approaches Kamen Rider Drive, he looks at his belt, noticing it isn't the Drive Driver, but a blocky silver buckle lit by a red orb in the centre. "You… ain't him, are you?!"
"An impostor!" Kamen Rider Wizard shouted.
"Even worse than an imposter! He's—" Kamen Rider Den-O responded before being ejected.
Kamen Rider Drive suddenly hard-turns right to shake the place, tripping both Kamen Riders as the floor tilts over.
Kamen Rider Den-O and Kamen Rider Wizard are flung out of the mecha down to the rest of the crew's feet. When they roll onto their backs, they power down from their Kamen Rider forms. "Senpai, what happened?!" Urataros helps up Momotaros as Kintaros helps Haruto.
"Did you get hijacked?!" Gentaro asked them.
From the torso, a red dash leaps out and touches down before them: Kamen Rider Drive… or is it? As he presents himself to them, they look at his belt in surprise as he pulls the sides out and removes a card illustrated with his image. As he shows them the card, he powers down not into Shinnosuke, but a well-dressed brown-haired man with a magenta twin-lens camera hanging from his neck. "Decade!" they all exclaimed in surprise.
"That's my name, don't wear it out."
"Agh, I should've known. Tomari's too humble to take the spotlight like that. It makes sense you'd be the one to do this." Momotaros growled. "What gives you the right to butt into my experiment?!"
"I was in the neighbourhood, heard Shinnosuke couldn't make it, so I thought of subbing in. I have a card for that shuriken, after all." Tsukasa explained as he presented a card illustrated with the Drive Shuriken.
"Damn you…" Momotaros clenches his fist.
Gentaro approaches Tsukasa. "Hello, I've heard about you, seen you around the past few team-ups. I never actually got the chance to properly talk to you. I'm Gentaro, Kisaragi Gentaro, and from this day forwards, you're my friend!" he declares as he extends his hand to him.
"Likewise."
Together, and as if in sync, they perform Gentaro's secret handshake: gripping his hand, inverting down, a fist bump, then pounds it up and down. "Wow, you already got it down!" Gentaro said in surprise.
"I've met another version of you in another world. Harukaze Gentaro was his name. Good kid, just like you." Tsukasa explained. "Anyway, I need all your help for something, something I've been meaning to do in a long time." Tsukasa says as he circles them. "There's a certain world I've had my eye on, and I need some extra hands to help."
"If you need Kamen Riders, I'm sorry to say I—" Gentaro refused before Tsukasa butts in.
"By the way, I believe this is yours." He produces a crystalline device with four switches along its length and a rectangular screen in the centre; the Fourze Driver.
"Fourze Driver!" Gentaro exclaimed in surprise as he holds the belt in his hands. "How'd you find it?!"
"That's not important. What's important is if you guys are willing to help out a fellow Kamen Rider."
"And what makes you think we'll help you?" Momotaros crosses his arms.
"I finished that robot for you." Tsukasa pointed out as he turns to the mecha behind him. "Call it a favour, Rider-to-Rider."
They all look up to the gestalt towering over them, gazing at its chaotic yet harmonious design, incorporating elements of Kamen Riders throughout the years into one single construct.
"I guess it's pretty neat." Haruto commented before turning to Momotaros. "Even though he threw us outta the robot, he finished it like he said, and I don't have hard feelings about that. I say we should help him."
"Helping others is what heroes like us Kamen Riders do, especially when another Kamen Rider's in need." Gentaro agreed with his signature smile.
"Hmmm…" Momotaros put his hand on his chin, looking up at the mecha in thought. "On one hand, he stole the show like he does all the time, and from me of all people, ruining the design for Kamen RiderOh that I wanted…" he presented one point. "…Although I've been meaning to get back on the saddle and do something as a Kamen Rider!" he pumps himself up as he presents this other point.
Urataros sighs. "One thing leads to another, and now…" he clutches his face. "Ah, I give up. I'll do what you're doing."
"Tsukasa, I hate your guts, but I'll never turn down a chance for some real action!" Momotaros agreed, putting his hand on Tsukasa's shoulder, which is soon removed by the mysterious man brushing it off.
"So, what does this adventure entail?" Kintaros asked Tsukasa.
"I'm going to another world, one without Kamen Riders, one further away from any world with Kamen Riders. In that world, they have their own brand of hero protecting the Earth with giant robots such as the one we made. But there's an outside threat looming, many even. They're going to need help of not just one Kamen Rider, but as many as I can muster." Tsukasa explained.
"Who are these heroes? What's their name?" Momotaros asked Tsukasa.
Then, Tsukasa smiles and straightens his posture confidently. "They're called the Power Rangers."
