Kamen Rider Zi-O, Dimensional Descent

They probably never would have guessed.

Another Ultimate Kuuga was not defeated; in fact, he even transformed into a gigantic form three hundred meters tall.

That terrifying figure, with just a stomp, would be enough to destroy the entire city of Mitakihara.

And that's exactly what it intends to do.

"Hey... Danger! That guy's really planning to flatten the whole city!"

The roaring Alien Ultimate Kuuga, capable of destroying everything with a single move, lifted its foot and slammed it down towards the city.

"...Tsk."

In such a critical moment, Yan Ming had no choice but to step forward.

boom!

With a flash of emerald green light, the descending black foot was completely blocked.

Another figure was also rapidly growing larger—

"J!"

After taking out the Kamen Rider J watch and pressing the button, Yan Ming, who was in Zi-O III form, also gained the same power.

An endless power enveloped his body in a layer of green light as he blocked the enormous foot while continuously enlarging his body—

In an instant, Yan Ming's body also grew to a height of three hundred meters.

However, that's not enough.

If we continue fighting here, we will only destroy the entire city... the entire Earth!

Om-!

He immediately raised his hand, and a portal to another dimension that originally belonged to Galaxy Woz appeared in mid-air.

The enormous portal enveloped them all in an instant.

Boom boom boom boom—!!

Endless sounds swept through the city, no... this was no longer Mitakihara City.

The portal expanded, not only transporting them to another world, but also transforming the entire world into a vast and boundless universe.

But can such a simulated universe really stop the monster's invasion?

Boom-!

The next moment.

Everyone standing in the Milky Way saw one of the enormous figures fly backward.

"Yan Mingjun!"

The person who was knocked away was Yan Ming.

In contrast, Another Ultimate Kuuga gently clenched his five fingers, his face expressionless.

But it always feels like a mockery.

"This guy! Why did he suddenly become so strong?"

"It's not time to give up, my Demon King—!"

Gates and Wozniak's voices echoed in his mind, and Yan Ming shared the same thought.

For an instant.

His body transformed directly into a ghostly blue shadow.

Whoosh—! Extending space and time at a speed exceeding that of light, Yan Ming arrived directly behind Another Ultimate Kuuga.

Not only that, even his fists shimmered with three colors of light.

That immense power has been amplified to its greatest extent ever: overload, compression and expansion of spacetime, and cosmic forces from the end of the galaxy—

Such an exaggerated blow landed on the expressionless Another Ultimate Kuuga.

The brilliance of the Milky Way and the stars was instantly dimmed as a result.

boom--!!!

An invisible torrent swept across the entire simulated universe. Countless crack-like things could be seen gradually forming at the top of that space, which might even affect the real world.

but.

"how is this possible?"

Everyone witnessed that scene.

That punch, delivered with all his might by the third-generation Zi-O.

—They couldn't budge the black monster at all.

A faint wisp of smoke drifted from the monster's face, causing even the usually astute Yan Ming to step back in slight surprise.

That punch just now only left a faint mark on the other person's face.

That's all.

Yan Ming did cause damage... but even with his full strength and all the support he could, it was only a small pebble-like injury.

The Otherworldly Ultimate Kuuga merely waved his arm dismissively.

Light is like that.

The immense impact and unpredictable power transformed directly into black and gold lightning.

In an instant, Yan Ming, who was in full power, was knocked into the depths of the Milky Way.

Zzz—BOOM!

Then, the mimic universe exploded.

The Milky Way, stars, all star clusters and black holes in the universe were destroyed in that instant.

The entire universe shattered, and Yan Ming and everyone else's bodies returned to Mitakihara City.

Also returning together was that enormous figure, three hundred meters tall.

"Well…!"

This is perhaps the first time I've been in such a sorry state.

All three who had combined to form Zi-O III were tragically disintegrated. Woz and Geiz, without exception, collapsed to the ground, covered in wounds. The injuries suffered by Zi-O III were shared by all three of them.

Yan Ming knelt on the ground, panting heavily, his hands trembling slightly.

It has reached its limit.

"He's... ridiculously strong..."

Wozniak and Gates both looked up with wry smiles, but this was anything but funny.

The enormous monster continued to stare intently at them.

At the same time, he unleashed all his hostility.

"No, we absolutely cannot let it go any further!"

Then, a dark figure jumped up.

That was the Ultimate Kuuga, also in a black and gold form.

A fist brimming with the power of the entire body, wreathed in plasma-like flames.

That heavy punch landed squarely on Another Ultimate Kuuga.

Boom—!! A punch that could blow away even the clouds, but...

The enormous figure, three hundred meters tall, merely trembled slightly a few times.

It makes no sense at all.

Another Ultimate Kuuga swung his arm, and just that was enough to force Yusuke Godai to dodge.

"Let's all go together."

"That's right, if we combine everyone's efforts, we might be able to win! Just like before..."

"Hang in there, Mr. Godai!"

Kabuto, Hibiki, and Drive leaped into the air, while Den-O and Zeronos boarded their respective trains and sped toward the monster.

Then... they really went all out in their attack.

Transforming into Drive's strongest form, Shinnosuke bombards the opponent with massive cannon fire, then unleashes his ultimate attack, charging towards them with all his might.

"Ultimate move! Full Throttle! Tridon!"

"Maximum Hyper Cyclone!"

A combination of crimson and iridescent beams was launched, one being Drive's strongest attack, and the other a light cannon capable of destroying an area with a radius of one hundred kilometers.

Faced with such an exaggerated offensive, Another Ultimate Kuuga did something very simple.

Raise your hand, palm facing them, and release a beam of light.

A black-gold beam of electric current that can devour even all light.

The rushing black and gold torrent instantly surpassed the mere hundred kilometers in range, completely engulfing the two of them.

"Guwah—cough ahhhhh!!!"

The soldiers then landed on the ground.

Meanwhile, the two time-traveling trains continued their relentless pursuit.

"Don't underestimate us... Give us your full attack power!"

Den-O and Zeronos jumped off the train together, even colliding with each other as if the two trains were circling each other.

The merging and intersecting of time tunnels can cause a slight temporal runaway phenomenon, which might trigger an unparalleled explosion.

If that's the case, we might be able to win.

—That's the idea.

It can only be temporary.

boom!!

Then, all they did was stare.

The 300-meter-tall monster used some unseen force to forcibly fix the two trains in mid-air, compressing them.

Compress it to a small amount, then crush it with two fingers.

"Varied…"

Before they could be shocked again, the terrifying figure appeared behind them at an impossible speed.

At that very moment, Den-O and Zeronos were both swatted away like flies.

Hibiki, who attacked from behind with a giant sword, couldn't even break through the defense and was sent flying by Another Ultimate Kuuga in one blow.

boom--!!

And finally, there's Ultimate Kuuga, still unleashing a flying kick at full power.

But how long can such a futile struggle last?

One second, two seconds, ten seconds.

The black and gold monster just stood there and let him fight it.

Even if you use all your strength to punch and kick, even if you break down the object down to the scale of elementary particles—it's all useless.

A terrifying light erupted from his body.

At the closest distance, Yusuke seemed to see the future.

If that kind of power were to erupt in full force—

Everything here will be evaporated.

and so…
