Kamen Rider from the ancient times

"Fengdu..."

A bizarre figure, half black and half green with a white shawl fluttering behind his neck, stood atop the Tower of Wind, his gaze fixed menacingly on another, even larger tower that exuded an aura of evil.

"There's absolutely no tower like this in Fengdu!!"

Feeling his faith had been insulted, Shotaro Sakai went berserk and tried to rush over, but was held down by the other half of his body.

"This must be the world beyond our own, right? Our worlds might all be connected now. Before that, let's deal with the troubles below first."

The two-colored monster's right compound eye flashed, and Philip's voice rang out simultaneously.

Beneath the true Wind Tower lies a group of ordinary people being chased by monsters; this cannot be left unattended.

Shotaro Satoshi was able to prioritize, and after calming down, he jumped down without hesitation. Just as he was about to land, he created a whirlwind, and the monsters that were about to pounce on the crowd were blocked by the hurricane-like barrier.

call--

Kamen Rider W!

"Kamen Rider has come to our rescue!"

"Kamen Rider really exists!"

The children hiding under the tower shouted excitedly.

Kamen Rider W landed smoothly amidst the gust of wind, then spun around and kicked without pause, repelling the monster that lunged at him almost within reach. He then extended a finger towards the enemy ahead, and two voices rang out simultaneously—

"So, count your sins!"

"The universe—is here—!!"

"Whoa?!"

The sudden, deafening shout beside him startled Shotaro. He jumped back and turned to see Kamen Rider Fourze, dressed in white space armor, raising his hands high, as always in high spirits.

After he looked over, Kamen Rider Fourze also turned to look at him, and then stretched out his arm and gave him a thumbs up!

"We meet again, W!"

Gentaro Kisaragi's cheerful voice rang out.

"And OOO, long time no see!"

"what?"

Upon hearing his voice, Shotaro turned to look at the other side and discovered that a familiar Kamen Rider had also walked out to his right.

However, compared to Kamen Rider Fourze, Kamen Rider OOO didn't have any exaggerated entrance lines, so Shotaro Hidari was spared a second fright.

Hino Eiji nodded and smiled, "It's been a long time, Gentaro, and Shotaro and Philip."

Shotaro finally realized what was happening and looked around at them: "It's you guys again."

"Senior, let's fight together!"

Gentaro Kisaragi clenched his fists with great excitement.

This isn't the first time three people have teamed up!
……

……

At the same time on the other side.

Two more red Kamen Riders emerged from the vortex. They looked around, and before they could even figure out what was going on, they instinctively threw a few punches and dealt with the charging monster.

There was a crowd hiding behind them, and someone called out their names, and then they appeared.

"Kamen Rider Faiz!"

"Kamen Rider Drive!"

Amidst the excited cheers of the crowd, the Orphnochs and mechanical mutants that attacked them were all annihilated in the battle with the Kamen Riders. Only then did the two red-bodied Kamen Riders, who had repelled the monsters, have a moment to assess the situation.

Then they looked at each other in bewilderment.

"skillful?"

"Shinnosuke".

Kamen Rider Faiz nodded in response.

After confirming that it was someone he knew, Tomari Shinnosuke looked around at the situation with even more suspicion and uncertainty.

"It seems like we've entered another world?"

Having experienced the "History Change Machine Incident" before, Shinnosuke Tomari quickly grasped the situation, but wondered what had happened this time.

Takumi Inui realized some of the reasons: "Someone summoned us because—they need Kamen Riders."

There was a strong will that brought people into this world because some people needed Kamen Rider.

Tomari Shinnosuke looked back at the excited and surprised crowd watching them, and vaguely understood what was going on. Then he heard a sharp and piercing scream from the other side.

Like a child.

Has a child been attacked by a monster?
The refuge was temporarily free from monster harassment, and after exchanging a glance, the two decisively headed there.

"Is it the Shocker organization again?"

Shinnosuke Tomari still feels lingering fear about that incident.

"Not necessarily. It's more like another kind of spacetime distortion caused by changes in history. Those things shouldn't have come from this world in the first place."

Qian Qiao pointed to the Sky Wall emitting red light in the distance, then looked at the huge World Tree-like building on the other side, and the two Wind Towers, one large and one small, located two streets apart.

These buildings are clearly out of place in this world, and there are even strange meteorites that seem to keep falling from the sky from time to time.

"Moreover, I sensed a familiar presence."

Qian Qiao lowered his voice and said something else.

He raised his hand and touched the Faiz driver at his waist.

This time, he transformed into "Kamen Rider Faiz" using the Faiz Phone, not another power medium, even though his current body should no longer be able to use this belt.

Qian Qiao remembered the person who told him to live a good life in the new world—and this was the dream that person had entrusted to him.

Will we ever see it in this world?
The two rushed to the place where the scream had come from.

A quick scan of the battlefield revealed a group of unfamiliar monsters cornering two children against a collapsed wall. However, at that moment, two other Kamen Riders were already fighting these monsters.

"Ghost?!"

Shinnosuke Tomari knows one of the Kamen Riders.

The Kamen Rider who occasionally floats into the air like a ghost to attack is none other than Kamen Rider Ghost, who met Kamen Rider Drive not long ago!

As for the other Kamen Rider with the particularly flamboyant fluorescent pink hairstyle, Shinnosuke Tomari didn't recognize him.

Even during combat, the opponent would unleash exclamation marks from their attacks, creating a lively and exciting atmosphere.

"Boom! Boom! Boom!"

Several monsters were quickly blasted into a ring of flames by their fierce attack.

The fluorescent pink Kamen Rider made a gesture as if he had completed a game, then nodded to Kamen Rider Ghost, who was fighting alongside him, before turning and running towards the two children hiding under the wall.

Kamen Rider Ghost then looked in the direction of the other two, and raised his arm in surprise to greet them: "Drive!"

"Zun?"

Shinnosuke Tomari quickly stepped forward: "How did you end up in this world too?"

Kamen Rider Ghost - Takeru Tenkuji!
He smiled and said, "It seems like they heard the children calling out, and when they looked over there, they saw a whirlpool and came over."

Upon hearing this, Tomari Shinnosuke and Inui Takumi exchanged a glance. They seemed to have heard some sound before they came over, and then, without warning, they turned around and entered the vortex that suddenly appeared behind them.

"correct!"

Takeru Tenkuji turned back and pointed to the fluorescent pink rider not far away, saying, "Let me introduce you, that's Kamen Rider Ex-Aid!"

“Ex-Aid…”

Kamen Rider Drive, with tires hanging from his body, glanced hesitantly at the Kamen Rider with the punk hairstyle.

What do you want to complain about...?

Then I felt like I wasn't qualified either.

Takumi Inui said thoughtfully, "It seems that we Kamen Riders are not the only ones who have appeared in this world. If I'm not mistaken, they should all have come here."

They—in the events triggered by the "History Changing Machine"—saw far more than just these Kamen Riders.

……

……

Somewhere in the city, two Kamen Riders appeared in a shopping mall, somewhat bewildered.

Even though they were completely bewildered, when they saw the monster, they still slashed down with both sword and claw, and the monster, which was within arm's reach, exploded into a ball of flames and disappeared.

"Undead?"

"Not Undead?"

The navy blue Kamen Rider looked in surprise at the monster in its Undead form, then at the sword he had just slashed out with, and even had a card ready to be thrown out of his hand.

But the monster was directly destroyed under such an attack, and there was no need for cards to seal it.

Kamen Rider Blade scratched his head, then looked at his own posture with a puzzled expression.

His Blade Driver should be with Tachibana-senpai right now, and it's also a question why he's here, since he was filming just before this.

At that moment, cries for help came from the chaotic crowd in the shopping mall.

Someone's been attacked by a monster?!

In an instant, it felt as if an electric current had flowed through his body. He remembered that just a second before he appeared in this place, he seemed to have heard a similar cry for help.

The mall was a mess, with flames from the explosion mixed with thick smoke, and the figures of some monsters could be vaguely seen moving around inside. The navy blue Kamen Rider immediately ran towards that direction!

wow——

He charged through the billowing smoke and dust, but just as he was about to unleash his attack, he noticed a pair of golden compound eyes opposite him, resembling those of a bat.

What kind of monster is this?

No! This is Kamen Rider!

He immediately turned sideways and withdrew the sword he had swung at!

The Crimson Kamen Rider, who also emerged from the smoke on the other side, realized the problem and suddenly changed the direction of his claw-like attack, sending it crashing down onto the nearby shelf!
"Bang!"

The two Kamen Riders passed each other, staggered a couple of steps to regain their balance, and then turned around to look at each other in bewilderment.

"Eh?"

"Uh?"

After confirming that the other party was not a monster, they noticed something and looked towards the direction of the crowd. Without hesitation, they rushed over together and successfully eliminated the Undead and the Fangblood in the smoke.

The mall caught fire when the monster appeared out of nowhere and attacked the crowd, but many people were still trapped inside.

After assessing the situation, the navy blue Kamen Rider quickly said, "We can talk about everything later. First, evacuate everyone—by the way, I'm Kenzaki Kazuma, Kamen Rider Blade!"

"Uh? I'm Kiva, Wataru..."

Despite his ferocious appearance as a scarlet bat monster, Kamen Rider Kiva, who seemed somewhat shy, hadn't even finished speaking when Kamen Rider Blade, after introducing himself, eagerly rushed into the smoke.

Hongdu paused for a moment, then quickly followed.

……

……

On the towering Tokyo Tower.

"this world……"

The red-armored Kamen Rider stood on the edge of the iron tower, his head, resembling a rhinoceros beetle, turned slightly, and his azure compound eyes silently watched the battle on the ground.

He saw giant monsters he had never seen before taking over the streets, and he also saw a Kamen Rider who seemed to be using magic.

But none of that matters—

Kamen Rider Kabuto looked up at the sky.

The sky, shrouded in dark clouds and sandstorms, was constantly bombarded by meteorites carrying both protozoa and alien insects.

As Kamen Rider Kabuto watched the disaster unfold, he slowly raised one finger and pointed it towards the sky. The next moment, his figure disappeared from the tower, and the falling meteorite shattered with a deafening roar!

"boom--"

The explosion in the air attracted the attention of some people.

But not many people can afford to be distracted.

……

On the street at this moment.

The sudden appearance of monsters brought a huge crisis to the unprepared city and its people.

Besides some monsters of similar height, there were even some more terrifying giant monsters nearly ten meters tall clinging to the walls, and here appeared a warrior wielding a sonic baton.

At this moment, a fiery red magic circle suddenly appeared in mid-air, and then several chains flew out to control the giant demonic monster that was trying to pounce down!

Kamen Rider Hibiki turned his head and saw a Kamen Rider who looked like he was wearing a magician's robe appearing not far away.

Kamen Rider Wizard gracefully raises one hand, revealing a magician's ring on his finger, from which the chains that bind monsters appear.

"Come on! It's Show Time!"

The energy of magic and sound waves vibrated, and the gigantic demon was destroyed with their combined efforts.

However, looking around, even more monsters were surging into the streets. Even though Kamen Rider could protect humanity, this situation ultimately required a complete solution.

"A world overrun by monsters?"

Kamen Rider Wizard observes the world's situation thoughtfully.

This wasn't Haruto Soma's first time fighting in a team battle like this. After sensing a voice calling to him, he didn't need to be forcibly swallowed by the spacetime vortex. He proactively opened the magic circle and walked towards it.

Then I saw countless monsters, and Kamen Riders that appeared everywhere.

Hibiki glanced at him, but before he could say anything, he suddenly realized something and looked up at the sky above. He saw a huge robot being thrown out from behind a silver curtain.

"Boom!"

The Time-Space Demon Machine crashed not far from them.

Following closely behind was a magenta figure that leaped out from the aurora curtain and casually stepped onto the Time-Space Demon Machine.

Both Hibiki and Wizard were stunned for a moment upon seeing this.

"Decade?"

After they finished speaking, they subconsciously exchanged a glance.

At that moment, hurried footsteps and shouts came from behind them.

"Make way, make way—bang!!"

Hibiki and Wizard quickly dodged to the side, and the clumsy crimson monster rushed through them, running towards the Time-Space Demon Machine that had fallen not far away.

This is definitely a monster...

The reason why the two Kamen Riders didn't attack instinctively might be because the other was too unreliable.

The already damaged Time-Space Demon Machine opened the gate while emitting smoke. Another Den-O staggered and fell headfirst. Just as he was about to get up, Kamen Rider Decade jumped down next to him and stepped on his back.

"You think you can go back in time and change history again? How naive!"

The Crimson Demon spoke casually, about to kick Another Den-O away, but just as he raised his foot, he was knocked away by a Crimson Another Demon that pounced on him.

He hopped on one foot and stumbled, his emerald green compound eyes looking dangerously at the otherworldly god.

"Hey……"

"Dang! Are you alright? How are you?!"

However, Feng Talos completely ignored him, and after kneeling down to help Another Electric King up, he shook him excitedly.

Decade watched as the alien Electro King's brains were practically being shaken to their core.

"Stop talking!"

Another Electro shoved Feng Talos aside in a fit of rage, shouting in a voice laced with complex emotions and despair—

"It's all fake! There's no such thing as Kamen Rider! Hahahaha—Kamen Rider simply doesn't exist!"

The Other Rider intensified his negative emotions.

Hisanaga hoped that Kamen Rider could save his brother, but he spent eighteen years in this hopeless wait, resenting the Kamen Rider who failed to save his brother and resenting everything he had once believed in.

Gazing at Another Den-O who had uttered those words, Kamen Rider Decade's eyes flickered, and he drew his Rider Card Sword.

"Get out of the way, I'll show him what Kamen Rider is all about!"
