When two worlds clash, a new story begins!
"What is that!?"
Tomari Yuuki(OC Kamen Rider Dark Drive) and Shijima Yuriko(OC Kamen Rider Tracer) step out from the NexTridoron as the latter points to the sky, where a large purple portal can be seen forming.
Several others nearby also notice the mysterious phenomenon as they all look at it with visible concern and fear.
-X-
On the rooftop of a nearby building, Kadoya Tsukasa(Kamen Rider Decade) looks at the same portal with a serious expression as he holds his signature Blackbird Fly 135 Twin-lens Reflex Camera(Decade Pink) in his hands, ready to take a picture of the portal with said device.
*Click!*
"And so it begins." He says as the sound of his camera's click can be heard.
-X-
As giant spaceships suddenly come out from the mysterious portal, they start to deploy several Machines(Machine Lifeforms from NieR: Automata) to attack everyone nearby.
*Boom!* *Boom!*
Musutafu City comes under the attack of these otherworld robots as they destroy and kill everything and everyone that comes into their sight.
Buildings are instantly destroyed and people are quickly disintegrated as chaos takes over the town.
-X-
Endeavor and several other Pro Heroes, led by him, gather together to fight back against the Machine forces.
"Prominece Burn!" Todoroki Enji cries as he unleashes a powerful fire attack that instantly blasts away an army of robots.
While that works against the lesser enemies, the higher-ranked ones just shrug that off.
*Smack!*
"Urgh…!"
The heroes soon all lay down, beaten and scattered across the ruins of a street.
An injured Endeavor is held by the throat by one of the main Machine figures, Adam(from NieR: Automata).
"Ha! Oh my! Is this all that the humans of this world are capable of? How disappointing." The humanoid-looking Machine mocks the No. 02 Pro Hero with a maniacal grin.
-X-
A platoon of Machines was about to kill the injured heroes Mirko, Ryukyu, Ingeniun and a few others when two unexpected figures suddenly came to their aid.
"Stand back! We will take care of things now!" Kamen Rider Lupin(OC Sako Kaito) tells them as he draws his Lupin Gunner(already in its Blade Mode.) "It's Show Time!"
"What!? Who do you think you are!?" Mirko cries in protest, but Ryukyu holds her back.
"It's not like you can do much to help anyway." Kamen Rider Chaser(OC Akira) tells the heroes as he brandishes his Shingou-Ax, sneering at them and further angering the Rabbit Heroine.
The two Riders then share a look of understanding as they charge towards the new menace.
-X-
"Why is a Roidmude here?"
Nejire asked as she and the other U.A. students captured by the Machine Lifeforms were placed inside a special cell.
But they weren't alone.
On the end of the cell was a Plain Spider Type Roidmude, he was on his knees as his torso and spread arms were being restrained by several energy chains wrapped around his body.
And to top it all, he was badly damaged, likely as a result of whatever the Machines were doing with him.
Curiously, as Nejire cautiously approached him despite the others' warnings, she found out that the unevolved Roidmude did not have a number designation on his chest plate.
Only the code S-T.
"A human?" The Plain Spider weakly asks as he slowly raises his head to look directly at Nejire. "Who… Are you?"
He showed no hostility towards her and the other humans.
-X-
"Damn…!"
Kamen Rider Tracer curses as she and her fellow Riders Lupin, Chaser and Halo(Melissa Shield) find themselves surrounded by stronger variants of the Machine forces.
Strong enough to put up a fight against Kamen Riders.
"You guys need a hand?"
The quartet looks above and sees six figures above them, ready to join the fight.
The first three of them are revealed to be YoRha Androids(From NieR: Automata) A2, 2B and 9S.
The fourth one is a skeleton-like being, his body wearing a dark cloak of sorts. The most prominent feature of this figure is his circular white grinning skeletal-like face with eyes that have no irises. This is Emil(From NieR and NieR: Automata).
The last two individuals were the most unusual, looking the most 'human' out of the six of them.
The fifth person is an 18-year-old teenager with dark skin, a pair of glasses over his green eyes and short light blonde hair. His current attire consists of a green flak jacket, dark blue pants and long-sleeve shirt and a pair of black boots. He also wears fingerless gloves with metal plates on the backhand.
But what caught everybody's attention is the fact that he has a Brain Driver around his waist and the Brain Brace around his left wrist.
This is Kitagawa Kazuya(OC Kamen Rider Brain).
Finally, the last person in the group is another teenage boy of 18 years old. He has light skin, a pair of obsidian-colored eyes and short black hair that sweeps upward and to the right side of his head. He wears a punk-style outfit, with a dull green formal shirt and dark blue tattered scarf, as well as a black cape-like garment with ripped sleeves and edges plus dark blue pants and black boot-like shoes. He wears a choker and wristbands, his bands are a matching set—black with silver studs.
And like the boy before, the sixth individual was also using Kamen Rider equipment. He has a MetsubouJinrai Forceriser around his waist as he holds the purple Sting Scorpion Progrisekey in his right hand.
His name is Mabuchi Ryuji(OC Kamen Rider Horobi).
"Let's go!" A2 cries as she and the others jump down, ready to join the fight and help the four Kamen Riders.
"Henshin!" Kazuya and Ryuji chanted as they transformed into their respective Kamen Rider forms.
[Brain the Kamen Rider!]
[Forcerise! Sting Scorpion! Break Down!]
-X-
Back in the special cell, Eve(From NieR: Automata) was about to kill Nejire and the others when the chained Roidmude suddenly broke free from his restraints, protecting the humans from the aggressive Machine Lifeform.
The Spider Roidmude delivers several palm strikes into Eve's stomach, pushing him back.
"You!" Eve growled as he glared at the Roidmude, clutching his stomach in pain.
The Roidmude turns to the long blue-haired girl.
"Thank you." He kindly tells Nejire, after receiving energy from her [Wave Motion] Quirk. "I was able to regain my strength because of you."
Nejire smiles at this.
"I'm glad." She replies, nodding to him.
The Roidmude focuses back on Eve.
"I won't let you harm anyone here!" He declares as a red energy suddenly envelops him, changing him to his human form.
*Flash!* *Blink!*
He now looks like an 18-year-old short-haired ravenette who has a pair of red eyes and light tan skin. His new attire consists of a red vest worn over a white shirt, a black scarf around the neck, blue pants and a pair of black boots. He also uses a pair of black fingerless gloves.
But the humans gasped when they saw him equipped with something unexpected.
The teenager Roidmude has a Drive Driver around his waist and a Shift Brace in his left wrist. And he was holding in his hand the Shift Heartron Shift Car.
This is Sakuraba Tadashi(OC Kamen Rider Heart).
"You're a Kamen Rider!?" Nejire questions him, eyes wide in shock.
"By the power entrusted upon me as a Kamen Rider, I shall defeat you!" Tadashi declares as he adopts a fighting stance, then glaring at Eve. "Henshin!"
[Drive! Type Miracle! Heart the Kamen Rider!]
-X-
A giant Tower suddenly manifests in the center of Musutafu City(It looks exactly like the one that appears in NieR: Automata).
On top of said Tower, Kamen Rider Dark Drive and Izuku, wearing his Deku hero costume, can be seen fighting together as they are facing the mastermind behind the Machine forces' attack.
The enemy leader looks like a large, black, heavily-armed mechanical dragon, with two blood-red eyes lined up vertically on his head. He has several long spikes on his upper body and many smaller ones running down his back and his long, curved tail. He has a flamethrower as his right hand, and his left hand has four fingers with claws that can be launched, but he has no legs. This mechanical being also has grown a pair of mechanical wings on the lower part of his body.
This is Deus Ex Machina - Phase Omega.
And in the center of the arena, where the three of them now fought, a crucified Kamen Rider Kikai, who has been turned into a statue, can also be seen.
-X-
*Boom!*
"Argh!"
Despite their best efforts, Dark Drive and Deku are eventually overwhelmed by Ex Machina's power as both of them are blasted away.
With the fight also being broadcast to the whole world as the fate of humanity rested on the duo's shoulders, the audience could only grimace and lose hope as they saw how Ex Machina was about to kill the two humans.
But suddenly, a YoRHa Flight Unit comes into view as it can be seen flying around the Tower's top.
A2 is the one piloting it, and she is holding the Kikai Driver's Spannerder and Screwder.
"Everyone… Is waiting for you!" She cries, looking at the sealed form of Kamen Rider Kikai. "Wake up!"
A2 then throws the pair of golden items at Kikai, hoping that they finally activate him and release him from his prison.
But Ex Machina wasn't going to let her get away with this.
He gathers energy before firing a deadly beam from his eyes.
*Flash!* *Zap!*
*Boom!*
The laser hits one of the Flight Unit's engines, making A2 lose control of it.
Everyone watching the events unfold could only gasp and cry in horror as the female Android loses altitude and her flying vehicle eventually crashes on a spot near the Tower.
-X-
"A2!"
From within the audience, 2B, 9S and the others with them cry for the Attacker Android's name, fearing the worst.
-X-
Ex Machina opens his giant mouth, ready to devour and kill both Dark Drive and Deku, the two humans lying on the floor and unable to move due to their injuries.
-X-
Within the audience…
"Tomari-san!" Yuriko calls her partner.
"Deku-kun!" Ochaco calls her friend.
-X-
But suddenly, a golden armored figure gets in the way and stops Ex Machina.
"What!?" Deus cries in disbelief, unable to believe that someone was actually able to stop him.
And the newcomer is revealed to be none other than Kamen Rider Kikai!
"He's back!" Dark Drive cries in relief.
The new Rider helps the black one and Izuku stand up. The two masked men then look at each other as they nod in agreement before preparing to face their giant enemy.
"Kamen Riders! Why do you interfere!? Why side with the humans!?" Deus demands from them. "Mankind is worthless and selfish! They deserve to be terminated!"
In response to this, Dark Drive pulls out the Trailer-Hou and prepares to fire a powerful energy blast back at their enemy.
"There's no real reason! That's how it has always been! You don't need an excuse to help someone in need!" Dark Drive cries as Kikai and Deku can be seen sharing their energy with him in order to empower his Trailer-Hou's power. "It's as simple as that! A monster like you would never understand what humanity's true worth is!"
-X-
Deku, Dark Drive and Kikai manage to combine their forces and defeat the large form of Ex Machina.
However, that was just the beginning of the fight against the leader of the Machine Lifeforms.
"Hahaha! Do you really think you've won?" Ex Machina mocks them as he changes forms from his large dragon-like one to a more humanoid-like appearance, with him also shrinking down to have the same size as humans. "You've only defeated my weaker form!"
He now has a black armored body, a pair of black eyes with red irises, a torso with a rocket engine in the center. His head has five long quills with white stripes and markings around his eyes
He also possesses more pronounced body armor, with black and curved shoulder plates, larger gauntlets and leg armor with pointy kneecaps that have white outlines, a plate covering his pelvis and elf-like red shoes. He also sports a spiky belt with a black cape that protrudes out of the back of his waist.
This is Deus Ex Machina - Phase Omega.
-X-
Once again, the trio fights against their final enemy, combining their powers.
However, Ex Machina easily obliterates the two Kamen Riders and Deku, forcing the former two out of their respective transformations.
Now beaten and lying on the floor, a tired Izuku could only look up as Ex Machina looked down at him and the others while his figure was floating high in the sky. His dark figure casting a large shadow over everyone else.
"All life heads towards death from birth. Yes, everyone perishes over time." The villain announces, spreading his arms. "But not me! I have achieved perfection! I will create my perfect world and soon rule it as its rightful God!"
The monster began to laugh as humanity seemed to have lost all hope in overcoming this new crisis.
Frustrated, Izuku punches the floor as tears fall from his eyes.
"So in the end… I can't protect anything… Or anyone at all!?" He cries in shame.
The greenette then hears some footsteps as he turns around, seeing someone approach him.
It is an 18-year-old boy that has bright blue eyes and brown short spiky hair. He wears a jacket of which the collar of the jacket is red and pleated.
Underneath this, he wears what appears to be a gray vest with a button and several white, angular patterns on it. He wears a third layer under this, in the form of a plain, high-necked, black shirt. He also has a chunk of dull green and gray blue armor on his midsection that appears to be under his vest, and another piece of armor on his left shoulder.
He wears pants that are colored in shades of grey, black, and white. He also wears an ornate, dull green and grey blue piece of armor on his upper-left arm, along with a black and white checkered wristband. Like Aqua, he wears two criss-crossing straps on his chest, on which he wears a silver-colored emblem of Kamen Rider Kikai. His boots resemble an armored version of normal street shoes in shades of dark bluish grey, dull green, and red.
Lastly, the teen has the Kikai Driver around his waist, indicating that he is Kamen Rider Kikai.
This is Oozora Yuuma(OC Kamen Rider Kikai).
Like Izuku, Yuuma was also badly injured as a result from their fight against Deus Ex Machina.
"Not yet!" The older teen tells Izuku, making the green-haired boy stop crying. "It's not over yet."
"But we've got no more power." Izuku replies, looking at his damaged hands with a downcast expression.
Yuuma looks at Izuku with a firm expression, one full of determination.
"Miracles can happen when you go beyond your limits. A new power you can only attain then will manifest." He tells the younger teen.
It's at this moment that Yuuki catches up with them, and he is also shown to have sustained his fair share of injuries. The man still has the Drive Driver around his waist and the Shift Brace on his left wrist.
"Get up, Izuku!" The cop tells Izuku. "We can still save the world!"
"We can…?" The U.A. student asks back, still doubtful.
But feeling somehow inspired by the two of them, Izuku slowly adopts his own determination as he looks back at the Kamen Riders, nodding to them in understanding.
Izuku, Yuuma and Yuuki all think about the people important to them, the ones they cherish and wish to protect.
"The real fight…" Yuuma says first, focusing on his Kikai Driver.
"The real fight…" Yuuki says next, clenching his right hand around the Shift Brace.
"The real fight…!" Izuku says last, raising his right fist.
"The real fight starts now!"
The trio cries in unison.
"Henshin!"
Golden, silver and green energy pillars of light suddenly manifest from each of them respectively before combining into a single white one that is powerful enough to blast Deus Ex Machina away.
*Bam!*
"W-What!?" The Machine God cries in shock.
When the white pillar of light fades away, it's revealed that Izuku, Yuuma and Yuuki all fused together in order to give form to a new Kamen Rider.
A rainbow-colored aura enveloped this new Rider, his form was being concealed and only a single figure's silhouette could be made.
When three hearts become one, a miraculous Kamen Rider is born!
