Kamen Rider Zi-O, Dimensional Descent

Tsukasa Kadoya couldn't help but narrow his eyes.

"...A new Demon King, what does that mean?"

"It seems that Woz found him. He's a teenager... or a young man? Anyway, he's a boy."

"Right now, he seems to be in some kind of world... I'll tell you the exact coordinates."

"Oh, right, there seems to be another incredibly powerful guy who's also looking for that Demon King."

Kaito Daiki told Kadoya Tsukasa the coordinates of the world.

Even though Tsukasa Kadoya himself doesn't understand terms like spatial mathematics, he can still correspond to relative coordinates using his own driver.

"Incredibly strong... just how strong is it?"

"Who knows? Anyway, it was just a casual remark."

"Well... thank you for the information."

"So, how do you plan to repay me?"

"I'll treat you to a meal later, that should be fine, right?"

hum-

A silver-gray aurora curtain then unfolded before Tsukasa Kadoya.

What are you planning to do?

"What they plan to do... isn't it obvious?"

Tsukasa Kadoya chuckled and took something else from behind him.

Magenta...driver.

"Go and have a brief meeting with that demon king."

"Don't worry... I'm very gentle with my juniors, and I won't hurt anyone without reason."

----------------------

This is a place unknown to most people.

Villages, forests, and inhabitants resembling those of the Middle Ages.

Everyone lives here peacefully and amicably.

until a certain moment.

Suddenly, an enormous silver-gray curtain appeared in the sky.

"Wh-what?!"

"What is that?!"

The villagers looked in shock toward the curtain, but even more shocking things were about to happen.

From behind the curtain.

Two people slowly descended to the ground.

They both landed smoothly on the ground.

"Woz."

Shilun Yanming, and Woz who followed closely behind.

The two looked around in all directions... This was a new world.

"Is there any new information recorded in the book?"

"...Not yet."

Woz opened the book, but it was just a blank page.

"However, I suppose we'll get new information soon."

"Just like in the last world."

Yan Ming didn't say much, he just nodded.

"Also, my Demon King... You came to this world through Kamen Rider Decade's Aurora Veil, which is essentially different from the world that the Time Demon God went to."

"Aren't they all about arriving in another world? Why is there a difference?"

I've never heard of anything like this from Woz before.

However, just as Wozniak was about to explain something...

At times like this.

A scream then came from the other end of the forest.

"Aaaaaaahh ...

Both Wozniak and Yan Ming's expressions changed at that moment.

"This is…"

It's obvious without even thinking that someone must have been murdered.

"Woz, prepare for battle."

"You've only just arrived in this world and you're already planning to meddle in these matters, my Demon King?"

It seems that Woz wants Yan Ming to observe the situation first before making a decision.

However, Yan Ming will not choose that option.

"If someone is in trouble, especially in front of me, I will of course choose to help them."

"Whatever the situation."

After saying that, Yan Ming disregarded Woz's thoughts and ran directly towards the direction from which the screams came.

"Seriously... this Demon King is really hard to deal with."

Woz shook his head helplessly.

So he followed closely behind.

…No.

Before that, Yan Ming took out a watch face.

------------------

*Pfft!*

Blood splattered across the walls.

A man fell to the ground because of the other party's bayonet.

"Dad, Dad!!"

A blonde girl, probably in her teens.

And another, even smaller girl with twin ponytails.

"Run... Anri! No matter what... don't turn back!"

The blonde girl clung tightly to the other person, tears streaming down her face, and ran off into the distance.

The soldier who casually killed the man looked over with a cold smile.

"Oh, and that little girl too, right?"

"It looks really good, very youthful."

"Since she can't run for long anyway, why not just play with her like a cat playing with a mouse?"

"Okay, okay! Hehehe!!"

As they let out chilling laughter, these so-called soldiers then reached out their blood-stained hands to their opponent.

—Buzz.

A massive silver-gray barrier then unfolded from mid-air.

"What, what is this?!"

Beneath the soldiers' shocked quarters.

From inside the barrier, a figure leaped directly in.

boom! !

That was the sound of a soldier's skull being violently struck.

He was struck by the opponent's knee, blood gushing from his nostrils, and even the bridge of his nose was shattered.

Then it crashed directly into the wall in the distance.

"W-what? Where did you come from?!"

Ignoring the soldiers' voices.

Yan Ming glanced around.

…It was all the blood and corpses of the villagers.

"Didn't make it...tsk."

"Hey...where did you come from, kid?"

"Don't be ungrateful! What have you done to my most important teammate?!"

"It's that kind of setup anyway, right? This nosy bastard who popped up out of nowhere, kill him, kill him now!"

"What can you do with that weak and pathetic body of yours? Useless! You're about to be killed, aren't you? Hahaha!!"

The soldiers' mocking voices echoed in his ears.

"OK then."

So Yan Ming closed his eyes.

"...Since you've gone to such lengths..."

"Then don't blame me for being ruthless."

When I opened those eyes again.

A genuine killing intent then surfaced in his eyes.

That is—

The eyes that truly represent the name of the "Demon King".

----------------------

"…What?"

Somewhere else.

A soldier clad in black armor, and a figure as skeletal as a skeleton.

They then stopped.

"What's wrong, Lord Ainz?"

The black-clad soldier looked at the other person with a puzzled expression, but the skeletal figure simply stood there, stunned.

The voice, which only he could hear, echoed in his ears.

That is—the system notification indicates that there are other players nearby.

"Besides me... there are other people in this other world?!"

----------------------

"Oh dear, oh dear."

On a cliff somewhere.

Someone holding a camera took a few photos of the world.

Although they are all the kind of things that are unbearable to look at.
