Kamen Rider from the ancient times

When the world undergoes a strange change.

The destroyer of the world did indeed pause for a second to reflect on whether he himself was responsible for the problem.

But when he saw that there wasn't a single Shocker among the enemies, and that there was even a Time Jacker, he knew that he couldn't be blamed for this.

So he took the initiative and made his move.

"Probably..."

Kamen Rider Decade gestured to the large monster not far away: "I discovered this guy's plan, and then, I started fighting her."

Kawahara crossed his arms: "Oh? So what level of battle is it?"

"emmm..."

The magenta Kamen Rider made a gesture as if to explain, but the next moment, the gigantic Another Rider, tens of meters tall, charged towards the group, so he naturally turned around and joined the battle.

This Another Rider's appearance vaguely resembles Kamen Rider 1, but its lower body is completely twisted and deformed, fused with a huge motorcycle chassis, making it look like a ferocious beetle monster parasitizing machinery.

"Zero-One is here too? Perfect, let's take care of you all in one go!"

A wild laugh emanated from Alien 1's body. The motorcycle tires beneath it spun wildly, carrying its heavy body straight toward Hiden or Man.

"Danger……!"

Hiden could only scream and run away.

His Zero-One Driver was stolen by the enemy during the first World Incident, and now even with the Progrise Key, he is unable to transform and fight.

If the real Kamen Rider Zero-One were killed, the history of this world might truly be irreversible!

Tokiwa Sougo quickly put on the Time Driver.

Then he took out a gold-plated watch.

GrandZi-O!

Kawamoto was standing to the side when he was suddenly forced aside by an invisible wave. When he turned around, he saw a stone statue of Kuuga emerging from the ground.

A golden clock and statues of twenty Kamen Riders rose up behind Tokiwa Sougo, who struck his signature transformation pose and let out a powerful shout.

"Henshin!"

Rumbling--

The sculptures of the twenty Kamen Riders, from Kuuga to ZiO, have had their surface mud removed, revealing their true colors.

『Kuuga! AgitΩ! Ryuki! Faiz! Blade! Hibiki! Kabuto! Den-O! Kiva! Decade!』

"W!" OOO! Fourze! Wizard! Armor! Drive! Ghost! Ex-Aid! Build! 』

『Kamen Ride——』

GrandZi-O!

The Kamen Rider statue transformed into beams of light and merged into Tokiwa Sougo's body, condensing into a magnificent golden form on his body.

Kamen Rider ZiO Grand Form - Here we go!
Tokiwa Sougo straightened up and suddenly noticed another figure beside him. He turned his head and saw a red Omnipotent Kuuga who looked like he hadn't been "absorbed" by Grand Zi-O.

Then the other person turned to look at him.

After a long silence as their compound eyes met, Tokiwa Sougo seemed to understand: "Kawahara-senpai?"

Kawahara then looked away.

Tokiwa Sougo: "..."

So when did you transform...?

At this moment, Hiden Aruto was still desperately dodging Another 1's pursuit. Kamen Rider Decade leaped between them in time, raised his Rider Card Gun and fired continuously. The beam hit Another 1's shell and sparked, barely stopping its charge.

But faced with such a gigantic enemy, Decade seemed to be struggling to cope for a while.

After realizing what was happening, Tokiwa Sougo drew his Time Limit Sword and charged forward.

Swish!Swish!Swish!
In the blink of an eye, the three Kamen Riders leaped up from different directions almost simultaneously, attacking the massive Another One!
The red figure took the lead, golden lightning flashed, and he swung his right fist, which glowed with a fiery light, as he charged towards Alien 1's face like a cannonball.

A simple, direct, yet powerful punch.

"boom!"

The fist slammed solidly into the carapace on the monster's forehead. Alien 1 tilted its head back, letting out a painful howl, and swung its huge claws to try to strike, but Kawahara had already landed on the front wheel of its body. After the gust of wind swept over its head, it used its feet to perform a backflip and jump down.

At that moment, ZiO and Decade, attacking from the left and right, struck Another One with a sword and a gun respectively, leaving it no chance to retaliate. "Kuuga?!"

Another One let out a ferocious roar, its massive body staggering backward as it looked at the red Kuuga.

Why are you here too?!

Clearly, the appearance of someone before this had taken it by surprise.

At this point, Decade took out a card and swiped it.

The sound of the driver reading plays.

'Kamen Ride! Kuuga!'

His figure switched to Kuuga Omniform amidst the mosaic-like light effects, then he put away the Rider Card Box and clapped his hands.

"Now I have two free slots."

"..."

Kawahara looked at him.

Seeing this, ZiO, who was standing next to him, also looked for the location of Kuuga's nameplate on his own body, but his dangerous thoughts were stopped by a dangerous look.

After all, the Kamen Riders summoned by ZiO Grand ZiO are actually the Riders themselves, but most of them are in an unconscious state.

For example, Kawahara, who was summoned twice.

This is why Kawahara wanted to take back the Arce control head.

So Tokiwa Sougo pretended nothing had happened and withdrew his idea, following in the footsteps of Decade version Kuuga, and launched an attack on Another One.

Following Kawahara's stance, Decade used the momentum of his jump to deliver a powerful flying kick to Another 1's abdomen!
"boom!"

The mechanical carapace emitted a dull thud, and Alien 1 staggered, angrily swinging one of its massive forelimbs at Decade, who immediately jumped back to dodge.

At this moment, Emperor ZiO rushed forward and slashed down with his sword. His figure moved at high speed around him, delivering several attacks that exploded into intense sparks.

Alien 1 roared, its tires suddenly accelerated, and its entire body spun in place like a tank. The enormous force knocked back ZiO and Decade, who was trying to attack again.

The next moment, several energy projectiles scattered around like flowers falling from the sky as it spun at high speed.

"Boom! Boom! Boom! Boom!"

The surrounding area was covered by intense bombing. Feidian and the others had already retreated to one side of the battlefield, but now they were almost hit by the indiscriminate bombing.

Kawahara looked at him, and in an instant, he appeared in front of Hiden Aruto, who was screaming and trying to escape, and dragged him to a corner.

Decade and ZiO, who were not far away, also quickly dodged the energy blasts. When the intense bombardment stopped and the smoke and dust dissipated, Alien 1 was no longer in the center of the battlefield.

"Escaped?"

Tokiwa Sougo looked over there.

At that moment, Tsukuyomi ran out of the manor: "It's terrible, Sougo! The Time Jackers..."

At this point, Tsukuyomi paused, glancing hesitantly at Hiden Aruto on the other side. Hiden Aruto seemed to realize something as well, and hurriedly rushed into the manor.

This is where he grew up.

So the enemy appears here...

Decade looked at Hiden Aruto's retreating figure: "I was a step too late when I arrived. It seems that the Time Jacker wanted to fundamentally change the history of this world, so after I discovered him, he came to this era."

"scholar."

Then a hand was placed on his shoulder.

Kawahara said meaningfully, "Don't think that you're okay just because you've become like this."

Tsukasa Kadoya: "..."

At this moment, Tokiwa Sougo stepped forward: "This was caused by the Time Jackers. I'm sorry, I still failed to protect the Knights' timeline."

The ability of time hijackers to alter history is impossible to guard against.

but……

Based on the current outcome, Kamen Rider Zero-One should also disappear due to the alteration of history.

Why does Hiden Aruto still exist?
