Kamen Rider from the ancient times

I've obtained this knight card once again.

Tsukasa Kadoya remained silent for a long time before he seemed to come to his senses and a strange smile appeared on his face.

He stood up, put the Decade Driver on his waist, and raised the knight card with only one knight emblem.

『KamenRide——』

"Arcle!"

wow——

A thick darkness erupted from him!
However, the condensed power did not manifest as Kamen Rider Agul on him, but instead a black whirlwind descended in front of him, just like when he first used this Rider Card.

So what comes next?

However, just as Tsukasa Kadoya was waiting anxiously, the slowly forming whirlwind suddenly dissipated.

He was suddenly stunned. Before he could react, countless dark green vines intertwined and grew rapidly to the size of his own height in the whirlwind.

Finally, the Helheim plant dissipated in a burst of golden light, revealing a figure wearing a white cloak and robe with platinum blonde hair. The man stood there with his eyes slightly lowered, as if he had fallen into some kind of slumber.

Tsukasa Kadoya stared blankly at the person in front of him.

Although he successfully summoned the guy, the guy's attitude did not bring him any joy.

So it failed after all?

As Tsukasa Kadoya stared at the miraculous Kawahara before him, he took a deep breath and was about to reach out to test him when the unresponsive man suddenly opened his eyes!
Swah——

……

……

A light appeared before Kawahara's eyes.

Then the scene slowly solidified, and the walls of houses belonging to the real world appeared before our eyes, but a dreamlike light particle was faintly emanating from the surroundings.

He snapped out of his daze in an instant, a feeling that seemed so distant.

A golden ray of light flew out from the void, connecting him to the timeline of this world, so that all the trajectories of the past and the future were laid bare in his mind.

Floating in mid-air, Kawahara looked down indifferently at the scene below, where he saw the alien Decade struggling in pain, and Tokiwa Sougo standing next to him with a look of astonishment.

This is the time before the "Source of Time and Space" was born, and in order to achieve his ultimate goal, he must now create this power.

No one can stop it!
……

"Boom!"

Nine to five hours a day.

Suddenly, a loud clattering sound came from the next room. Kawahara, who had reappeared there, ignored it, looked at his divine form, and then raised his hand to conjure a pitch-black control display.

"You... Kawahara?!"

A young man's voice, filled with surprise and uncertainty, came from the doorway.

Kawahara glanced at him, then placed the "Arcle Ridewatch" in his hand next to the Ridewatch's storage stand.

"So you really do exist in this world! Wait... how did you become like this? And how did you get in here?!"

The young man strode forward aggressively.

He questioned Kawahara and was about to grab him by the collar when the latter dodged to the side, then crossed his arms and sneered.

"Who are you? Don't try to get close to me."

Tsukasa Kadoya: "???"

Kawahara said in a sinister tone, "Destroyer of the world, I'm warning you not to talk nonsense! Otherwise, you might get killed by me~"

"are you crazy!"

If you make too many connections with people from the past when you go back in time—especially with someone like the "Destroyer of the World" who has special characteristics—it can easily lead to another different timeline.

Although the birth of a new timeline will not affect the future of the unchangeable "sacred timeline," having an extra world is still quite troublesome.

Seeing Tsukasa Kadoya's frustrated expression, Kawahara, unusually interested, curled his lips into a smile, opened a spacetime vortex along the timeline, and then turned and left.

"Wait, you-"

Tsukasa Kadoya instinctively tried to follow, but was instantly thrown back by a powerful impact.

He groaned and rubbed his head. In his dizzy state, he seemed to see a dark and empty space that inexplicably made him feel uneasy.

After a long while, Tsukasa Kadoya slowly came to his senses and turned to look. He saw a black driver's watch lying quietly on the table.

This looks like it was left here by that guy.

next moment--

"Clam?"

Upon sensing the power of Arc, Tsukasa Kadoya became somewhat embarrassed and angry.

"For that demon king?!"

If they obstruct Decade's power in every way, won't ZiO's power also disrupt the world?

Damn that guy!
……

In the void of darkness.

Kawahara's will scans the timelines in all directions, witnessing the recurrence of all sorts of past events.

He met Kouta Kazunaba, who did not become "Kamen Rider Gaim" but still became the "Origin Man", and in a moment, he also stared at Oma ZiO in time and space.

From Kamen Rider Build to Kamen Rider Kuuga, countless Kamen Riders from different timelines have passed before his eyes.

Suddenly, someone called out to him. Following the direction, Kawahara looked over and saw a timeline spreading out from the dark void.

The red lines fell onto his body, and the timeline of this world surged into his consciousness.

Kawahara was somewhat surprised, and then guided this timeline that had flown in on its own into the "Source of Time and Space".

Having seen many worlds where people are determined to escape being dominated, this is the first time I've seen a world that actively asks to be "dominated," even though Kawahara believes that the "unalterable timeline" is itself the only truth.

Even from a distance, the two hearts are still breathtaking!
While actively opening the door to countless possibilities in that world, it also preserves the world's existing history.

Perhaps this is another way out that Hearts 2 has explored for the remaining Undead. The war between races is bound to be brutal, but if they don't have the chance to win a second ultimate war for their race, they can still try their luck in other worlds.

Because such a possibility is permitted.

But no matter how they plan, Hearts 2 will not allow the already developed human race to be overthrown, so "anchoring" to the past is also necessary.

……

As time goes by, the river continues to flow upstream.

Gradually, the surrounding scenery became extremely familiar and relaxing, even causing him to stop and linger.

He saw Kana Okamura in her office, struggling with piles of documents with a headache. Shiro Mizushiro, sitting on the sofa next to her, seemed to sense something, but his gaze did not focus on him.

"Huh? How..."

Kana Okamura's voice, which had suddenly become sensitive, gradually drifted away in time and space.

Then the surrounding scenery also became unreal.

Moving further along the timeline, Kawahara encountered Ashihara Ryo, who was walking with a girl in black cycling gear by the roadside on the riverbank.

Suddenly, a small yellow dog ran out from under the grassy slope and bumped into the two of them. Ryo Ashihara was slightly surprised, then picked up the small yellow dog, which seemed to be still nursing.

The girl next to them smiled and said something, and the atmosphere between the two seemed quite good.

Kawahara watched in surprise, and remembering the unlucky luck of that poor kid Ashihara Ryo, he couldn't help but wonder what would happen next.

But when his will fell on Ashihara Ryo, before he could pull out the timeline, Ashihara Ryo, who was petting the dog, suddenly had a violent emotional reaction, let out a painful groan, and knelt on the ground.

The forest-green Gills phantom flashed past him, and the girl next to him, caught off guard by the sight, screamed in terror.

Swah——

Unexpectedly, Ashihara Ryo's senses were so sensitive that Kawahara quickly withdrew his probing intent and then pretended that nothing had happened and slipped away.

If this guy breaks up with his girlfriend later, that's absolutely none of his business...

This is fate's choice!
However, these Agitos seem to have incredibly sharp senses. Kawahara only glanced at Tsugami Shoichi, who was cooking, from afar, and the guy immediately looked at him alertly, though his expression remained blank.

……

After distancing myself from those exceptionally sensitive subatomic entities.

Kawahara met Ms. Enokida, who was chatting with Kaoru Ichijo, at the police research institute. Gene was leaning affectionately against Ms. Enokida's chair, and the three seemed to be discussing who they could gather.

Some topic came up in the conversation, and Kaoru Ichijo sighed with a rather helpless smile.

These three people should be oblivious. Kawahara pulled up their timelines, watched the wedding with interest, and then left.

Wait...that's not right!
That doesn't seem to be Enokida and Gene's wedding?
Kawahara looked too fast and glanced back before realizing that the bride at the wedding they were attending was Sasayama Nozomi, and the groom was the same Officer Sakurai from back then.

Bad news: Kaoru Ichijo has been single for ten years.

Good news: He actually caught the bride's bouquet!

Ms. Enokida and Gene did not hold a wedding ceremony; the two quietly remarried.

It can be said that I have started a different new life.

Kawahara then looked at the others.

The shop manager, Shikatama, is muttering to himself while keeping accounts in the café, followed by Asahina Nana, who is excitedly sharing the good news that she has finally gotten the script for the female lead after all her hard work.

As for Sakurako Sawatari and Shuichi Tsubaki, the two of them also began to live a long-term life away from home.

The former is obsessed with excavating and researching various ancient relics, while the latter uses his outstanding clinical experience to travel to medical experimental bases in various countries for research and study.

Judging from this, it looks like they won't be coming back for a long time.

……

But these are all things of the past.

He needs to stabilize this timeline first.

Kawahara did not linger any longer; guided by the timeline, he captured another special moment.

He reached out towards the thing and grabbed a strange plant seed. In an instant, the entire trajectory that had occurred at that point flooded into his consciousness.

At first...

It turns out he almost killed off a piece of Kamen Rider's history.

That was something that was forced into ultimate darkness by the Raven Master, who was driven by the Black God.

After everything was over, the only thing Kaoru Ichijo didn't tell him was the fact that Kamen Rider G3—Makoto Hikawa—had been killed by him.

Although the clumsy police officer himself seemed to have forgotten this fact.

But whether it was Kaoru Ichijo or Sumiko Ozawa who witnessed it firsthand, they both knew what terrible things had happened during the encirclement and suppression of the "Agito Capture Plan".

Although not as significant to the world as Kuuga and Agito.

but……

They're all Kamen Riders too!

Whether it's G3, Gills, or other AgitΩs who have awakened the power of light, they are all Kamen Riders who are protecting humanity and the world!

After regaining his senses, Kawahara sighed softly and crushed the rose seed in his palm.

"Crash..."

In the present world, a woman who had dived into the deep sea looked in astonishment at the seed she had left behind, and found a card that read "Time Descends" among the shattered light.

Using the rose seeds that connect with her as a medium, she seemed to see some illusions of time and space before the seeds disappeared in the ripples of light and shadow on the water.

What a mysterious Lindo warrior.

……

As time marches ever forward, there are some things we simply have to face.

When Godai Yusuke first saw the "Amadam Spirit Stone" outside the Kurogatake ruins, he seemed to sense something again, but when he looked back, there was nothing unusual in the half-collapsed cave ruins.

The world changes rapidly, spring comes and autumn goes, flowers bloom and wither; time seems to be moving forward and also moving backward.

An old, dark hand rested on the stone coffin, then in an instant, the hand became young again, its fair wrist adorned with a bracelet made of seashells, pine cones, and feathers, exuding a mysterious yet natural aura.

"...Kawahara-sama?"

The girl's voice echoed in the silent cave, her empty, unfocused eyes gazing into the void.

“You know I’m here.”

Unlike others who could only vaguely sense his presence but couldn't find him, the girl, though blind, knew exactly where he was.

Kawahara emerged from the void, his platinum-gold figure radiating an ethereal light in the dimly lit cave.

Mio looked in his direction, a gentle smile playing on his lips.

"Actually, I didn't expect Lord Kawahara to come at this time. It's so good to see him again!"

Kawahara gently squatted down beside her.

The figure of the girl in front of him was also illusory.

Mio lost her sight due to fear during the Grongi attack, but the reason she lost her sight was because she awakened the power of light at that moment.

Such powerful light not only deprives the body of sight, but also the soul of vision.

The Mio who appears in the ruins at this moment is not her true form.

Because long before Rick sealed the Grongi, the mountains that served as the burial ground for the entire village were completely sealed off. Recklessly tampering with the seal would only cause those Grongi to revive prematurely.

Therefore, what enters here is only Mio's mental form.

"I want to see my brother."

Mio said softly, "Just take a look."

Her life is nearing its end.

Rick, who possesses the Amaddam Stone, will remain sealed for ten thousand years. Even Mio, who has become "AgitΩ", will not live to see that time. She wants to see it one last time before she dies.

Kawahara turned to look at the huge stone coffin beside him bearing the "Kuuga" crest.

Suddenly, a thought struck him. He raised his hand and drew a wisp of active will out of the stone coffin. The thin young man who had transformed into it opened his eyes as if he had been prepared.

"Mio!"

"Eh?"

Before Mio could react, he was suddenly embraced by a familiar scent, his unfocused eyes staring blankly ahead.

This young man was, without a doubt, Rick.

Kawahara sat on the steps beside the stone coffin: "I see. You had your own plans from this time onward, didn't you?"

"Kawahara-sensei!"

Rick turned back to look at him with surprise, but when he lunged forward, he missed completely, only managing to scatter a handful of illusory light particles. He looked at his hands with a blank expression.

Even though Mio, who is also a being of the thought form, can encounter each other.

“I’m not here at this time,” Kawahara said calmly.

"Great!"

Rick simply smiled again: "Then the future teacher must have gotten what he wanted by now!"

This guy is excessively naive, pure, and kind. Even though he doesn't really understand what "teacher" means, he still cooperates earnestly, and the responsibility he is forced to bear makes him give his all as a matter of course.

Only at the very last moment did Rick shyly reveal a hint of his desire to be willful.

“Teacher Kawahara, I’ve been thinking about what Amadam really is, what that darkness means, and what it has brought to Lindo and the Grongi…” Rick said in a low voice.

Kawahara looked at him without saying anything.

Rick then scratched his head with a憨厚 (honest and simple) expression and laughed, "In the end, I didn't figure anything out, haha..."

Kawahara: "..."

Mio couldn't help but chuckle softly.

Rick's gentle gaze fell on her, then he said to Kawahara with a hint of apology, "Kawahara-sensei, I... I don't want to continue fighting."

It's not because I want to escape.

He simply didn't want to fight anymore.

Rick turned to look at the stone coffin and said, "If the seal against the Gurongi can be maintained for ten thousand years, the Amadam Spirit Stone will choose the next suitable Lindo warrior. By then, the Lindo tribe will surely be very powerful!"

Although Rick hadn't figured out what the Amadam Stone and the darkness truly meant, he knew that this power would always protect Lindor.

After a long silence, Kawahara's dark, calm eyes fixed on Rick before him, a faint smile appearing on his face.

"OK."

Warriors chosen by the Amadam Stones are unwilling to fight, yet only those who "don't want to fight" can withstand the erosion of ultimate darkness.

Darkness dislikes humans killing each other, so it chose humans like this.

However, the ancient Lindo, who had not yet learned to kill, did not want to continue such endless battles in the future. Therefore, after Mio came looking for him, Riku also had the idea of ​​leaving with Mio.

He has missed Mio's entire life.

Without my sister, I don't want to fight anymore.

Rick's consciousness left the Amadam Stone, and what continued to guard the seal were only the warrior's body and unwavering faith.

Mio looked toward Kawahara, his eyes, devoid of sight, reflecting a blurry figure of golden light, behind which stretched an endless golden river.

She vaguely knew what it was.

Mio said softly at the end, his voice filled with joy.

"Thank you, Lord Kawahara."

……

Beyond the ancient times, there lies an era even more distant than the ancient civilization, a time when the world was under the absolute rule of darkness.

At the center of the world, two gods, one black and one white, are facing off.

The world was divided into two different parts: one side was a dark and gloomy sky with thunderstorms, while the other side was a bright and sunny sky with blue skies and white clouds.

The ground was transformed into a battlefield, with sand and stones flying everywhere.

The confrontation between the forces of darkness and light nearly destroyed most of the world. However, for the forces of darkness that created the entire world, such destruction is something that can be rebuilt. Therefore, he now only wants to focus on destroying the forces of light!
When the void of spacetime descended upon this place, the two people facing off sensed something almost simultaneously.

Dark Power suddenly looked up.

He sensed an aura from beyond the world.

He already hated the power of light touching the dark forces that he created, and he hated even more the forces from outside the world interfering with his world, so he didn't hesitate to take action to block them.

However, the power of light keenly sensed that this might be his last chance, so when the power of darkness was distracted, he also took action to interfere with it.

"Prometheus!"

Dark Force glared angrily at the white-clad youth opposite him.

Prometheus's expression was resolute. Having fought this far, he knew that he could not defeat the power of darkness.

But that doesn't mean he has no other means.

Just as Prometheus was about to spread his power of light to all of humanity, the aura captured by the interference of the dark power with the spacetime rift transformed into a sense that foreshadowed the influx of dark power.

At the same time, the power of light, which was separated from the power of darkness, also sensed something from the other side, and both of them were instantly invigorated!
Prometheus was overjoyed!

The power of darkness was stunned for a moment before erupting in fury!
The scenes from "Kamen Rider Agito" became prophecies that the two learned of. Seeing that they would actually be defeated by a human with the "power of light," their dark power was filled with anger and countless thoughts flashed through their minds.

"Ah!"

The power of darkness suddenly sneered, "Now that I know about this, the future of this world has already changed. Prometheus, this time you are destined to fail!"

"what you up to?!"

Prometheus had a bad feeling.

At this moment, the power of darkness separated a wisp of darkness from itself once again.

"Humans are so foolish and arrogant! Perhaps I cannot guarantee where my bottom line is with humanity, but since you used my affection for humanity to defeat me, then let this child be the one to complete the battle to wipe out all Agito in the future!"

Dark runes of dark power appeared before him, and to Promis's astonishment, the runes slowly transformed into a human-shaped child.

Dark Force revealed a confident smile.

"This child carries my will; he will do what I cannot do—annihilate all Agito!" When the power of darkness abandons its tolerance and love for all humanity, then its darkness is destruction and annihilation.

However, the power of darkness cannot guarantee that even if it has seen the future, it will not be defeated by the power of light time and time again due to its excessive love for the humans it created in imitation of itself.

He couldn't accept this result.

But he also didn't want to actually wipe out all of humanity.

Then, by channeling the will to "destroy Agito," we can create "another self" to accomplish this task!
This is a weapon that will never betray him!

Prometheus sensed the determination of the dark power to create this child.

The other party is right about one thing.

Since the future has been seen by the dark forces, it means that the future of this world will be changed. The space-time outside this world is ultimately unrelated to this world, and the outcome of "the dark forces being defeated by Agito" in the prophecy will no longer exist!

Does this mean that the fate of humanity in this world is forever controlled by the power of darkness?
No! Human destiny should be freedom!
The power of light also deeply loves humanity, but it does not want to control humanity's future. What it desires more is to see the miracles that humanity creates as it grows unrestrained.

Humans created fire themselves.

And so, "light" was created in the darkness.

Then, amidst the rain poured down by the angels, they unknowingly created tools that could provide shade and shelter from the rain.

Human beings clearly possess infinite possibilities!
Gazing at the child who possessed the "power of darkness" and bore the destiny of "annihilating all Agito," Prometheus made up his mind in an instant, and without hesitation released all the power of light within him!

boom--!
The blue skies and white clouds of the other half of the world were completely overtaken by darkness and torrential rain, but under the night sky, countless shooting stars shone brightly and spread to all parts of the world.

The power of light dispersed itself.

Then, before the dark forces could react, Prometheus, weakened by the dissipation of his power, forced himself to do one last thing.

At this moment, his body had lost all its strength and collapsed to the ground, but his will transformed into a beam of light that struck the darkness in front of the Dark Force!
Seeing this, the power of darkness tried to stop it, but the will of the power of light pierced through his darkness and instantly entered the child's body!

wow——

A burst of intense light erupted!
The ultimate darkness was instantly dispelled, and runes of light emerged from the child's body. In this power, one could vaguely see Prometheus's final, resolute gaze.

Finally, everything returned to calm, and only the sound of the torrential rain remained in the world.

Dark Power was stunned, with a hint of bewilderment in his eyes.

After a long while, he slowly realized what was happening and looked at the child floating in front of him in disbelief.

The child he created just a second ago, representing "another self," has now been possessed by Prometheus's own will!
The power of light alone may not be enough to suppress the will exerted by the power of darkness, but if Prometheus himself is involved, it is unknown whether this child will be able to continue to fulfill the mission of destroying Agito in the future.

more importantly……

The battle between the forces of darkness and light did not actually occur because Prometheus helped humanity fight against the angels, but because Prometheus bestowed the power of light upon humanity during the battle.

He dislikes humans who have been tainted by the power of light.

Therefore, he greatly hated Prometheus.

But now that Prometheus has suicidally dispersed his light power, he can no longer find a target to continue his revenge.

So at this very moment, the child before us, directly possessed by Prometheus's will...

After realizing what was happening, the Dark Force, filled with a complex mix of resentment, disgust, and confusion, held back for a long time before finally unleashing a torrent of uncontrollable rage!

"Prometheus—!!!"

……

Kawahara rarely witnessed how he himself had been thrown out of the world by the dark power that had driven him to madness.

His attention to the battle aroused the Black God's senses, and the spacetime fluctuations connecting the world to the outside world were detected by the other party. Gritting his teeth, the Black God directly tore open the rift, threw out the child, and repaired the rift in an extremely smooth process!
The Black God's reasoning behind this action was simple—since Prometheus had inhabited his will within him, it was a good opportunity for him to be banished from this world!

As for the future where Agito was defeated?
Ha! Prometheus has already been banished from the world by him, so the future has naturally been changed as well!

However, the humans in this world have already been affected by the light power emitted by Prometheus. The Black God, who has already sealed off the world again, has a cold look in his eyes and directly summons the other six archangels.

"Destroy...this world!"

The flood that covered the entire world roared down from the sky. The Black God did not look at the scene of the six archangels driving nature to destroy the world. He sat alone in the starry sky, watching the planet that was gradually being stained by the water.

He plans to exterminate this group of humans and then recreate a new human race unaffected by the "power of light".

This is the best possible outcome!

On this familiar cosmic platform, the ethereal Kawahara stood not far from the black-clad youth, seeing a golden line connecting him to the spacetime rift from earlier.

Kawahara's heart stirred, and he grasped this timeline, instantly seeing himself at countless points in time.

From this world to beyond, to the ancient times, to the modern times, to different Kamen Riders, no matter what, he will eventually return here.

There was no other reason than that he belonged to this world and simply wanted to return here.

Then kick the Black God.

……

……

As Kawahara left this space-time, the young man in black seemed to sense something and looked back, but all he saw was a tranquil universe.

He suddenly fell silent.

After his rage subsided, the Black God's consciousness returned to Earth, whereupon he heard the cries and struggles of all beings amidst the world-ending flood.

The children God created are praying for God's salvation, yet the destruction of the world is God's will.

Heishin can hear the voice of every human being in the world and feel the emotions deep in the hearts of every human being. The countless torrents of information are not an unbearable burden for him; in fact, they are quite commonplace.

Even in the most ordinary circumstances, the sound of crying and pleas for mercy lingered in his ears, and even the cold expression on Black God's face couldn't help but waver.

Human beings have indeed been somewhat foolish, greedy, and arrogant, but what wrong have they done?

Even if the arrogant humans wanted to rebel against his arrangements, possessing the power of light might not have been something they actively desired, and his children didn't truly want to betray him.

The Black God looked into the void and thought of the child he had abandoned from this world. What had that child, who knew nothing, done wrong?

Was his decision too arbitrary?

Stunned by the dwindling human voices, Kurokami felt a surge of sorrow.

God never regrets anything.

He merely stopped the destruction of the world.

……

Before the darkness, the world was still in darkness.

After tracing back to the source of the "unalterable timeline," Kawahara's consciousness suddenly felt empty and lost, unsure of which direction to continue in.

He just kept moving forward, and then a huge golden gear appeared in the darkness ahead.

At that moment, a vast torrent of information flooded into his consciousness, a world of countless possibilities.

The result of connecting the timeline by using himself as a carrier is that he can perceive the past and future of all parallel worlds in an instant.

From then on, the change of time ceased to exist in his cognition. His consciousness seemed to be immersed in a void that was even more distant than eternity, and his perception was so vast that it was no perception at all. Gradually, he even began to forget his own consciousness.

But right now.

A loud shout suddenly came from the other side.

"But I am—"

"Kamen Rider Decade!"

A figure appeared on the other side of the Wheel of Time.

Kawahara subconsciously turned his attention over, and when he saw the young man, information about him instantly flooded his mind.

No one can explore the Wheel of Time.

Apart from the twenty anchored Kamen Riders.

The young man was defeated by the enemy after traveling outside the timeline, but the Kamen Riders in the "Unalterable Timeline" are eternal and immortal, and the "Chrono Wheel," which embodies Kawahara's last will, will not allow such a thing to happen.

Therefore, the dead Kamen Riders can be revived by the Time Wheel and then return to the original timeline of the Riders.

But the destroyers of the world are a little different.

Given the chance, this guy can go anywhere; otherwise, he wouldn't have ended up outside the Holy Timeline and died.

Kawahara's dormant thoughts suddenly became active.

Along with this information, memories of experiences with different Kamen Riders also surfaced.

Just as he was savoring the moment, a silver curtain appeared from the opposite side of the Wheel of Time, and a vortex-like suction came from the other side, causing Kawahara to feel his consciousness uncontrollably drawn closer to it.

clang--!
Two hands of time, one long and one short, appeared in the dark center of the Wheel of Time. Then the minute hand turned counterclockwise, and a red knight's emblem shone on the disc.

……

On the beach under the blue sky and white clouds, a young man who was walking slowly along the coastline suddenly looked up at the sky.

"Did you make it……"

The young man exuded a calm and gentle aura, his eyes always revealing a kind of approachable sincerity, and the smile blooming on his face at this moment was even more tender.

As if trying to grasp a ray of brilliant sunshine, he stretched out his palm towards the sky.

"Me too--"

Kamen Rider Kuuga!

……

AgitΩ Restaurant.

Shoichi Tsugami, who has been studying Western-style pastries recently, seemed to have a premonition. He put down the piping bag of cream in his hand, wiped his hands, and smiled, "Then count my efforts in too."

"Kamen Rider Agito!"

……

ORE News Agency.

Shinji Kido, who was still an intern, examined the Time Descends card in his hand. Suddenly, he perked up and looked up at the sky with a firm and sincere gaze.

"I've always wanted to thank you, and please accept the power of Kamen Rider Ryuki!"

……

On a riverside highway in some other world.

The speeding motorcycle came to an almost instantaneous stop. Qian Qiao took off his motorcycle helmet and looked at the huge gear that was faintly visible in the air.

"You've made people wait long enough. Since you've entrusted others with protecting your dreams, you should at least witness them yourself!"

"My power—"

"Kamen Rider Faiz!"

……

"Ah, I kind of dislike that guy..."

Kenzaki Kazuma stopped cleaning, looking utterly dejected.

"Fine, anyway, that guy was the one who initially brought Kamen Rider Blade's power... I'll leave the ace of fate to you!"

Kamen Rider Blade's power transformed into a Spade Rider emblem, soaring into the sky and merging with the omnipresent Wheel of Time, then shining brightly in the river of time.

……

At this moment, the power of all the Kamen Riders converged into one point, responding to the will of Kamen Rider Decade that had suddenly been transmitted to him.

Hidaka Hitoshi smiled, gently pressed Hibiki's transformation tuning fork against his forehead, and then waved it towards the sky obscured by the tree canopy as if to say hello.

Heroes are everywhere.

"Kamen Rider Hibiki".

……

"Grandma said that I am the one who follows the way of Heaven and is in charge of everything."

Tendou Souji, passing by Tokyo Tower, slowly raised his hand, not even glancing at the giant gear flashing past in the sky, his posture leisurely and lazy.

"I have heard your wish. I will lend you this power for now—Kamen Rider Kabuto!"

……

As Hongdu was making a violin in the attic, facing the sunlight streaming through the window, he slightly raised his head, and then a thoughtful smile appeared on his face.

"Is it for Mr. Kawahara? Then please accept the power of Kamen Rider Kiva."

……

Meanwhile, a harmonious and friendly atmosphere of mutual responsibility was taking place inside the electric train.

"Here it comes! Of course, I'll have to do this kind of thing—"

"Let me go!"

"Get out of my way, you brat!"

"There's no point in arguing about this. Since both Momotaros and Ryutaros want to go, then let me go!"

"Sigh~ Little Jin, please stay seated. At crucial moments like these, we still need your help."

"Um...wait, everyone, stop arguing and listen to me—"

"—!!"

"Here I am! Kamen Rider Den-O!"

"Um... you don't need to transform..."

“…………Huh?”

……

clang--

As the hands of time passed, the Kamen Rider crests on one half of the disc flashed in succession, and then the crests on the other half responded to the call and lit up.

Kamen Rider W!

"Kamen Rider OOO!"

Kamen Rider Fourze!

"Kamen Rider Wizard!"

"Kamen Rider Gaim!"

"Kamen Rider Drive!"

"Kamen Rider Ghos!"

Kamen Rider Ex-Aid!

"Kamen Rider Build!"

"..."

An exam is being held at Hikarimori High School.

As Tokiwa Sougo struggled with answering the question using probability, he suddenly sensed something, and the boy's gaze sharpened at that moment.

The rooftop of this teaching building.

Wearing a gray-green robe, Woz was flipping through a book, and he was engrossed in reading about his past as the Demon King who failed his exams.

But the next moment, the history recorded in this book changed under some influence.

And there is only one person who can do this.

Woz sighed with a sigh, a helpless yet indulgent smile appearing on his face: "My Demon King, there's really no need for you to..."

Using the power of Oma ZiO to avoid failing his course was indeed making a mountain out of a molehill, but before he could finish speaking, he suddenly noticed something amiss and looked up.

The sky had darkened without anyone noticing.

A colossal gear, sending shivers down one's spine, roared through the void. Only when the oppressive, dark aura gradually faded away did Woz, who had been unconsciously suffocating, realize what had happened.

Having actively sealed away the "power of Oma ZiO" and his "memories," his Demon King was naturally not awakened for a minor exam.

—It is an unalterable, sacred timeline.

Woz paused, then turned to look at the classroom where Tokiwa Sougo was. The high school student at this moment was Oma ZiO, who also possessed memories of countless parallel worlds.

The sacred timeline guards countless possible worlds, anchoring an unchangeable past. Existing in the void, it is unexplorable and untouchable, yet it indulges only those Kamen Riders who have been imprinted upon it.

The current Oma ZiO exists to restrain the influence of those Kamen Riders on the Time Wheel.

only……

This kind of constraint is completely meaningless!

Tokiwa Sougo rested his chin on his hand, gazing at the sky outside the window. A meaningful smile appeared on the eighteen-year-old's face: "I'll help you this once. My power—"

Kamen Rider Zi-O!

……

Swish!Swish!Swish!
The moment the crests of all twenty Kamen Riders lit up, their history and memories became crystal clear, like sunlight piercing through dark clouds, awakening the dormant consciousness in the darkness.

but……

Kawahara stood on the other side of the Wheel of Time, almost face to face with Tsukasa Kadoya, who was reaching out his hand at that moment.

He remained silent and did not make a sound.

After discovering his own power of creation, Kawahara wondered and explored what the existence of the "Sealing Stone" meant to him.

—That was a medium for separating himself from the will of all things in the world.

The power of darkness is naturally unaffected because it is a god born from the world, but Kawahara was created by imitation and does not possess the ability to assimilate all things.

Therefore, when he decided to integrate into the "Wheel of Time," Kawahara was well aware that his consciousness would be affected by assimilation.

But that's exactly what he's going to do.

Only in this way can he ensure that he will not use this power to subjectively dominate the world in the future.

So when he saw the curtain leading to the present world appear before him, Kawahara hesitated in front of the Wheel of Time. After standing there for an unknown amount of time, he raised his hand and took out a Decade Driver.

He truly longed to return to those worlds.

But he also fears his inherent desire for control.

So, should we...?

The time of emptiness is a moment, yet also an immeasurable eternity.

Before Kawahara could find an answer to his inner turmoil, a hand suddenly grabbed his wrist, followed by twenty timelines intertwined from the starting point of the clock hands.

The resolute faces of those Kamen Riders flashed through his mind, and at this moment, memory and history acted as a barrier, cutting off his consciousness.

The Wheel of Time's leniency towards those Kamen Riders left Kawahara with no time to react, and in an instant, the scene before him changed.

……

Wow!
The storm seemed to have subsided.

He exuded a familiar aura of ultimate darkness.

—Why is it this thing again?!
As Kawahara regained consciousness, the force was suppressed. He then opened his eyes in the dazzling light, and a nervous-looking young man stood before him.

The bright afternoon sun shone in through the window.

Unlike the vastness and desolation of the void, the photo studio, decorated like a café, is equally tranquil, but it exudes a warm and peaceful natural atmosphere. The vitality of the present world floats under the sunlight, and everything is so comforting and pleasant.

Kawahara kept his calm gaze fixed on Tsukasa Kadoya in front of him.

The latter stared at him, slightly taken aback.

"you……"

"The destroyer of the world—"

Kawahara suddenly interrupted the other person.

“Speak your wish to call me, and then offer your soul for this summons!”

"...???"
