Kamen Rider from the ancient times

"Ah……"

On the almost frozen battlefield, a sarcastic and slightly hoarse chuckle rang out.

All eyes were drawn to that direction.

The crimson knight, standing in the center of the battlefield, was casual and arrogant, his emerald green compound eyes glancing enigmatically at the soldier not far away.

"It was just a sudden pang of pity, I didn't expect it to be exposed so quickly. What a troublesome guy."

"..."

The taxi driver looked tense upon hearing this.

But Kamen Rider Decade ignored his reaction, then looked around at the endless monster army in all directions, and finally looked at Narutaki above the plaza.

In his passionate state, his compound eyes, which were not particularly round, revealed an even more ferocious and sinister color. Decade became extremely angry at this moment, and even revealed a hint of madness.

"Narutaki—!"

Kamen Rider Decade roared and pointed his Rider Card Sword at the man.

"You've ruined my world!"

“I have investigated thoroughly. You led your Shocker Legion to invade countless worlds, wantonly destroying everything in those worlds!”
"You are a true demon—a destroyer of the world!"
"Now I have nothing left, so no matter the cost, I will defeat you myself!"

After this declaration of revenge was shouted out, not only was Narutaki slightly taken aback, but even the taxi driver and Natsumi were shocked!
Narutaki quickly realized what was happening.

Was it just Decade from a world that had opposed him back then?
Although he didn't know how this guy survived, since he had already been defeated by him once, Narutaki didn't care.

"Turns out he was just a defeated opponent."

Narutaki gave a disdainful sneer.

He waved his hand behind him, and a huge, black barrier reappeared, while Narutaki grinned as he looked at Kamen Rider Decade opposite him.

"I acknowledge your current strength, so let them deal with you from now on!"

As his words fell, nine figures emerged from the curtain, their familiar, now-gloomy forms standing in a line opposite Kamen Rider Decade.

"Kamen Rider?!"

Xia Hai exclaimed in surprise upon seeing this.

Eight of the Kamen Riders were the same ones she and Tsukasa had met in the worlds they had traveled through together.

But at this moment, the Kamen Riders' compound eyes were dim and lifeless, and a sinister and dangerous aura emanated from them, not to mention that they were on the side of the Shocker Legion.

This is undoubtedly the enemy's posture!
Shi looked over the familiar Kamen Riders and his gaze fell on an unfamiliar Kamen Rider in a red outfit.

—Kamen Rider Kabuto.

The man inexplicably learned the other party's identity.

So, is this the last Kamen Rider he hasn't met on his journey yet?

Tsukasa Kadoya calmly observed the Kamen Riders.

This is the Shocker Legion's trump card. In addition to creating countless monsters, Shocker also captured and brainwashed the Kamen Riders in those worlds, just like what they did when they used the "History Change Machine".

"To defeat Kamen Rider, you must use the power of Kamen Rider!"

Sensing the sudden surge of resentment from Kamen Rider Decade opposite him, Narutaki arrogantly spread his arms wide.

"So, will you once again flee alone to another world in a sorry state, or will you try to save them? Kamen Rider Decade!"

Narutaki was referring to Shi and Natsumi, who were captured in this world.

However, Tsukasa Kadoya did not answer.

He charged directly at the Shocker Knights who were controlled by evil forces, wielding the Knight Card Box Sword!
At that moment, the Shocker Knights over there also rushed forward under Narutaki's command, and in an instant, an extremely fast knight figure suddenly appeared in front of Decade!
Tsukasa Kadoya remained completely calm, only a light similar to that of the figure flashed at his waist.

『KamenRide——』

'Faiz!'

Silver and red photonic blood flowed on the armor, and the charging knight was only a blur in appearance. In the instant Decade transformed, his right leg shot out the same crimson energy as the one on the other side.

Final Attack Ride——

『FFF-Faiz!』

"boom!"

With a spinning kick, two crimson light cones that appeared in the air exploded simultaneously, but Decade remained standing in place, while Kamen Rider Faiz was slammed to the ground in the explosion.

Before the flames from the explosion had even dissipated, another familiar Kamen Rider rushed forward.

Perhaps to fight against these Shocker Riders, but also as if to demonstrate his power, Kamen Rider Decade is always able to transform into the corresponding Kamen Rider to fight with extraordinary reflexes.

The taxi driver, standing not far away, stared in disbelief at the battle, feeling a mix of shame and a surge of desire.

Can he become like that too?
Just as his thoughts were suddenly drifting to this point, the explosion that suddenly resounded beside him jolted him awake!
AttackRide——

Blast!

Decade, who had been changing forms to fight the Shocker Knights, had somehow reverted to his original form. He leaped backward to create distance from his enemies, and his Rider Card Box Sword transformed into a gun-like firing mode.

"Bang! Bang! Bang! Bang!"

Several energy blasts indiscriminately bombarded the Shocker Knights and those in all directions, also hitting the area not far away where Shiki and Natsumi were being held captive by the monsters. The explosions sent debris flying across the plaza, and the intense heat brought a dangerous atmosphere.

Those strange people instinctively resisted the explosion; it was impossible to say whether Decade did it intentionally or unintentionally, but the taxi driver realized something in that instant.

--It's now!
Taking advantage of the monster's momentary lapse in vigilance, the hijacked taxi driver suddenly elbowed the Bee Woman in the abdomen. In the instant the monster cried out in pain, he unhesitatingly pulled Xia Hai and rushed towards the alleyway by the roadside!

The bat-like monster, sensing something amiss, was about to give chase, but this time, several light-emitting bullets hit its body precisely!
"boom!"

The bat-like monster screamed and exploded into a ball of fire.

This sudden turn of events caught everyone present off guard.

Narutaki frowned, about to instruct several Shocker executives to give chase, when Kamen Rider Decade's voice suddenly rang out from beside him.

"You should worry about yourself!"

A crimson figure emerged from stealth and traversed the entire plaza. The light waves from the Knight Card Sword sent rows of Shocker combatants flying, while Decade leaped towards Narutaki at that moment!

In the indiscriminate energy bombardment just now, not only did Shi find a chance to escape, but the Shocker Knights on the battlefield also lost track of Decade.

But without a doubt, Kamen Rider Decade, who is declaring his revenge, has Narutaki as his ultimate target!
"boom!"

However, just as the Rider Kick landed, Kamen Rider Kabuto, who was chasing after him at super speed, appeared on the opposite side, and sparks burst in mid-air!
Kamen Rider Decade and Kabuto, who had been intercepted, landed on the ground together. Just as they regained their footing, Narutaki's angry shout, still shaken, echoed from the steps of the plaza.

"Watch this—you wretched Decade! As punishment for hindering Shocker's grand plan, everything you wanted to protect will be destroyed!"

"You are the complete and utter loser!!"

"……What?!"

Upon hearing this, Tsukasa Kadoya looked over in astonishment.

Just as the taxi driver and Natsumi were about to run into the alley, Agito, the Shocker Knight who had been targeting them, leaped down from the air under Narutaki's command!

A chilling sense of crisis crept in from behind, sending shivers down the spine of the fleeing taxi driver, who instinctively turned around.

The knight's figure, kicking towards them against the sunlight, was like a god descending, cold and deadly. But at that critical moment, the crimson figure that had been in the square appeared before the knight with uncanny speed—

"Boom!"

The shockwave from the Knight's Kick sent soldiers flying, and the brick walls on both sides collapsed under the energy impact. Amidst the billowing dust, Xia Hai's scream echoed, along with a fleeting glimpse of the Knight Card Wall.

Final Attack Ride——

Decade!

The taxi driver, lying on the ground, struggled to look up and saw the earth-colored figure being kicked away by Decade with a spinning kick.

Such a rapid counterattack seemed very cool, but the next moment, Kamen Rider Decade was crackling with electricity and suddenly staggered and knelt on the ground.

"That guy is really dark-skinned..."

A soft sigh came from Tsukasa Kadoya, it was unclear who he was talking to, and Tsukasa's voice seemed to be suppressed, he looked at him silently and could not say anything.

wow——

As Kamen Rider Decade's mosaic light effect flashed, he was hit head-on by Agito's Rider Kick. Tsukasa Kadoya was forced to exit his transformation form, and his disheveled and weak state clearly indicated that he had suffered a serious injury.

Xia Hai could sense that the life of the young man, who was also wearing a brown trench coat, was slipping away. He stumbled over from behind the collapsed wall, frantically and painfully trying to touch him, but then retreated out of worry.

"Shi, how are you—"

The face that looked exactly like Shi's lifted up.

As the smoke from the explosion dissipated, two men, Tsukasa Kadoya with similar postures but different auras, stared at each other.

"how come……"

Xia Hai covered his mouth in shock.

Shi regained his composure at this moment, but only looked at the other version of himself in front of him, who had packed him up and tied him to the attic, with even greater embarrassment.

"Why did you save me?"

With mixed feelings, Shi said, "Just like you said, I'm just a troublemaker. Is it really worth it to let your revenge fail just to save me? You must really like your world..."

Unlike him, who only wanted to escape his own world, the other self in front of him might be someone who loved his own world.

"Of course I love my world."

Tsukasa Kadoya curled his lips into a cryptic smile, looking intently at him: "That's why I need to do this even more."

The scholar was momentarily bewildered.

—Do this?

Does it refer to the incident of saving him?
Or does it refer to...

No one knew when the change occurred, but by the time those present realized what was happening, the entire world was suddenly shrouded in a dark and ominous atmosphere, as if a storm was brewing.

It was as if some ethereal, rumbling sound was resounding from the sky.

As Tsukasa Kadoya slowly looked up, he felt a pull from outside the world as his life force rapidly drained away.

—This is what I've been waiting for!
