Kamen Rider Zi-O, Dimensional Descent

A blond boy dressed in brightly colored armor stood respectfully before a beautiful woman.

"I see... Clem is really amazing, he managed to protect me from that monster's attack."

"No... I didn't do anything! It was that powerful, mysterious armored hero who defeated the demon, as everyone says. I... I was just staying in the royal city, responsible for protecting the princess."

"No, not at all! The fact that Clem is by my side is already the best thing for me!"

"Why do you say that, Your Highness..."

For a moment, the young knight seemed to blush with embarrassment.

"Ah...it seems like time is almost up, and Mr. Gerdoff seems to need to see me again..."

"It's okay, Clem, go ahead, we'll chat happily together later."

"...Thank you so much, Princess Lana!"

So the princess was left alone in the room.

A cute-looking girl stands by the window, gazing at the beautiful scenery outside.

"An armored hero who saves the country...?"

As the princess pondered what Clem had just told her, a smile of keen interest appeared on her face.

"This looks like it's going to be very interesting..."

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

The location is at the entrance to the Great Tomb of Nazarick.

Here, a group of guards appeared in front of the gate.

"I see."

Ainz Ooal Gown stood at the very front of the group.

Standing in front of him were Yan Ming and Woz.

"To leave this world... Come to think of it, you actually have the ability to leave this world?"

"My demon king and I will travel through countless worlds... So, King of the Undead, do you also intend to join us?"

If you're only using the Time Demon, bringing one more person along isn't actually a problem.

If Yan Ming were to use the Aurora Veil's power, even the entire Great Tomb of Nazarick could theoretically be pulled into other worlds.

only…

Ainz Ooal Gown glanced at his subordinates behind him and then shook his head.

"Thank you for your kindness, but I still have things to do in this world."

"oops…"

"To spread the name of Ainz Ooal Gown throughout the world... and then, to search for whether there are any of my former comrades in this world."

Even without it, Ainz Ooal Gown still felt that this other world was very strange.

A world-class artifact capable of controlling Shalltear... such a thing could never have been created by the natives of this world.

Moreover, there are many similar myths in this world about people falling from the sky.

It's very likely that there are other players here.

To unravel all these mysteries... one must remain in this world and continue to spread the horn of Ainz Ooal Gown throughout the land.

Yan Ming nodded, immediately understanding Ainz Ooal Gown's meaning.

"Then... the time for parting is fast approaching."

"Oh...are you leaving already, Mr. Yan Ming?"

"Your Excellency possesses truly formidable strength. Although you are merely human, we are willing to show you our respect."

"Although... well... anyway, I'm very grateful to you for stopping my foolish act of attacking Lord Ainz back then... otherwise, I would have regretted it for the rest of my life."

"Shalltear, you've got to be ridiculous! You were the one who got defeated, and you still have the nerve to say goodbye?"

"What did you say? You shorty!"

"Oh dear, your intelligence is truly remarkable. I rarely wish to have a discussion with a human... What a pity."

"...I have taught you all the skills I can. Now, I hope you can gain far more experience than I have."

All the familiar people, including guardians like Shalltear and Sebastian, all the familiar guardians, spoke to Yan Ming and Woz with great respect.

The time for parting is approaching.

"You guys, step back for a moment."

"understood."

The guards immediately vanished from their spot, leaving only Ainz Ooal Gown at the entrance.

He then turned his head and looked at his only friend in this world.

"I'll come back again."

"Ah, definitely... For you, that's just a short future."

"That's good."

Ainz Ooal Gown nodded; he was willing to trust Yan Ming.

His former companions had to leave the world of YGGDRASIL due to some unavoidable problems in life.

But this newly acquainted companion would not do that.

Although he will leave, he will definitely come back here again.

"I hereby swear an oath."

Ainz Ooal Gown raised his hand high, aiming it at Yan Ming.

"Ainz Ooal Gown will be your most loyal companion... forever!"

The two needed to say more.

The relationship that develops between them during this short period of time... is what is called "friendship".

then.

In Wozniak's book, golden light once again shines upon the world.

"This is--!"

Yan Ming grabbed the beam of light that flew out, and it instantly transformed into a blue and white watch face.

"Blade!"

"A new force...?"

"This is... Kamen Rider Blade's watch face. Congratulations, my Demon King! It seems that your friendship with this King of the Undead has successfully earned the recognition of the power of Kamen Riders who are also friends with the Undead!"

Moreover—if the watch face can fly out, it means that the history of this world has been recorded to its fullest extent.

It's time to move on to the next world, no matter what.

So, to be on the safe side, the two of them used the safest means of transportation to move around.

"The Time Mazine!"

Huge, robot-like vehicles appeared in the world.

Without hesitation, the two entered its interior and manipulated it to traverse the tunnel between dimensions.

Ainz Ooal Gown watched them leave this world in silence.

I felt a little reluctant to part with it.

However... he did not let this get him down.

I will remember the words that my friend conveyed to me, and then... maintain my humanity and bottom line, and then spread the name of Ainz Ooal Gown to every corner of this world!

"Well then, it's about time that adventurer Feifei made her appearance again..."

Ainz Ooal Gown turned his cloak and disappeared at the entrance to the Great Tomb of Nazarick.

Until the next time my friend returned.

————————————————————————

Then, a whole new world soon followed.

Yan Ming manipulated the Time Demon God and entered that new world in one breath—

"--This is?!"

The moment they entered this world, the smoke of destruction filled the air.

After landing in a relatively calm place, the two realized just how... terrible this world really was.

The sky was dark brown.

All around were destroyed cities and streets, and the natural environment was also in a terrible state.

Then--

In the distance, one could see countless armored warriors riding motorcycles, chasing after the city.

"That's... Leo's cavalry?!"

Moreover, under Woz's watchful gaze, countless watermelon-shaped samurai figures flew across the sky.

"Kamen Rider Shadow riding inside a watermelon lockseed...why are there so many of them?"

In the distance, one can see... a dark brown figure, resembling a gamer.

"This time it's actually a driver from the Ex-Aid world...?!"

What exactly is going on? This world…

"Woz, can you find out what happened?"

"…This is…"

Woz opened the book, trying to find as much new information as possible.

However, it only recorded one sentence.

"To achieve final victory in the world of the Knight Wars and become the 'King of Time and Space,' surpassing all other Knights."

In the darkness, the figures of countless knights locked onto this direction.

"It seems the fierce battle between Kamen Riders... is finally about to officially begin."

The white knight, his eyes gleaming with golden light, slowly retrieved the memory device from his waist.

"Eternal!"

"Come on... let me experience the pleasures of hell once more!"

Volume 4, Rider Wars: Chapter 69 The People Being Chased by Kamen Riders

Yan Ming and Woz walked down the street.

No… because it’s so dilapidated, you can no longer tell if this place was ever a street.

The surrounding area is filled with destroyed cities, and the traces of human life are very strong... but the only thing that cannot be found is a race called human.

Smoke and fire continued to rise from within the city.

The sky was always a deep brown.

Countless knights moved in succession in the distance, some riding motorcycles in groups on the ground, and others constantly patrolling in the air in flying armor.

At first glance, it seems somewhat similar to the world of Singularity F, the first place they traveled to... but in reality, it is completely different.

"What do you intend to do, my Demon King?"

The place where the two were located seemed to be a relatively safe area, and there was no way that the knights would come to attack them.

"According to this book, this seems to be the world of the so-called... Knight Wars."

"You need to win this great battle so that you can successfully record the history of this world and gain new power."
