Kamen Rider Zi-O, Dimensional Descent

"That's right, that's why the two of us travel back and forth between different worlds."

Tiamat seemed to have sensed their presence as well.

The monster, now in dragon form, stared intently at the two humans who had suddenly appeared before her, but neither Tsukasa Kadoya nor Daiki Kaito were afraid of her.

On the contrary, Tsukasa Kadoya simply picked up the camera hanging around his neck and took a few photos.

"I don't know what that thing is, but the reason it became like this is indeed because of the 'Seven Deadly Sins.'"

"The Seven Deadly Sins"... This term has been mentioned once again.

"The 'Seven Deadly Sins' are a concept widely circulated in the demonic world. They are inherent in human nature and have existed since the primordial era. They are both demonic and an invisible, intangible concept."

"Where did you learn about these things?"

Upon hearing that Tsukasa Kadoya knew information that even he himself was unaware of, he immediately inquired about it.

"It was just information I gathered while chasing a guy named Asmodeus... You've probably seen him, haven't you? That guy who looks like a complete oddball."

I had heard from Asmodeus before that he had fought against Tsukasa Kadoya and Daiki Kaito.

"However, the focus right now should be on solving the immediate problem."

So the two of them turned their heads around.

They looked together at Tiamat before them… or rather, at the creator goddess who had been infected by the “Seven Deadly Sins” and had completely lost herself.

Opposite to them, Yan Ming, who had transformed into the third stage of Time King, also stood to their right.

"What else do you know about the Seven Deadly Sins?"

"Pride, envy, wrath, sloth, greed, gluttony, lust—each represents humanity's most primal sins, and each can bring unparalleled power to the possessor."

Hai Dong Da Shu said it directly.

"Arrogance can distort the mindset of the possessor, making them disregard everything and develop an absolute worldview centered on themselves, which can amplify their original power to the limit."

"Wrath and greed both represent hatred towards all things, allowing the possessor to gain greater power after each defeat and to continuously acquire new abilities that it did not originally possess."

“Envy is the ability to copy the opponent’s abilities to a limited extent; sloth is the ability to completely escape reality, not even including the existing definitions of time and space; gluttony is the ability to devour everything in front of you and turn it into your own power.”

"As for lust, it refers to a complete integration with a specific object, where one exists within the other at all times and in all places."

After Hai Dong Da Shu finished speaking, Yan Ming's reaction was relatively good, but Woz and Gates inside his body were both stunned for a moment.

"These two guys... they actually know so much?"

"Perhaps, after their battle with Asmodeus, they both encountered beings possessed by the Seven Deadly Sins in different worlds."

"In that case, it's not unreasonable for them to know all sorts of things... Besides, shouldn't the people responsible for explaining these things usually be storytellers like you?"

"You should visit other people's homes once or twice in a while, after all."

After learning all the information about the "Seven Deadly Sins" from Daiki Kaito and Tsukasa Kadoya, Yan Ming suddenly understood some of his previous questions.

So, the reason Tiamat was able to be resurrected from those humans and Rahm's bodies is entirely because a complete fusion relationship was formed between them.

That's right, this can be perfectly achieved by using the power of the concept of "lust".

This can be achieved by defining the fusion object as "all life born of Tiamat".

"So what's the situation now? Although it's called the 'Seven Deadly Sins,' none of the enemies we've encountered so far have been particularly difficult to deal with..."

"The current situation is that in order to completely defeat this monster, we must eliminate all life that is connected to her, and the life that is connected to her is everything on this planet."

"..."

Tsukasa Kadoya and Daiki Kaito both froze on the spot.

Because what this means... is to tell you indirectly that you must wipe out all life on Earth in order to eliminate the enemy in front of you.

"Are you sure you're not kidding us...?"

Of course, Tsukasa Kadoya knew very well that his words were meaningless.

There is no possibility that Yan Ming is lying; this is the situation of the enemy they are facing.

And now, there's no time left for them to continue speaking.

"Ahrrrr——!!"

With their explanation, Yan Ming understood the real reason why Tiamat was able to slowly break free from his control through his time manipulation abilities.

That's because of the power of "laziness." By using it, one can escape from the normal definition of time and space, as if escaping to another dimension.

boom!!

Before the two could say anything more, a tremendous force erupted from directly in front of them once more.

Rumbling--

Black mud spread across the ground.

"This is bad! The information about Tiamat's spirit origin... although it cannot be explained in detail, it has indeed expanded to an enormous extent!"

Under everyone's watchful eyes, Yan Ming immediately took out his strongest Time Limit Sword and slammed it into the ground.

"King! Giri Giri Slash!"

The golden light transformed into the ripples of a raging wave.

The light particles ejected from the blade erupted again from deep underground, and then spewed out directly from the ground beneath the black mud like magma, continuously scorching them.

The black mud was then burned away, and Yan Ming raised his head again, instantly creating several teleportation portals directly in front of them.

The portal connects to the deepest part of the black hole, which means that all the black mud will flow there.

but.

Bang—!! In an instant, the portal in front of them was severely damaged.

It is Tiamat.

Having transformed into a dragon, she roared ferociously once more and then charged towards them.

"What are you still watching? This is no longer the time to watch a play!"

Gilgamesh shouted, and everyone around him snapped out of their daze.

Not only Yan Ming, but all the remaining Servants began to take action.

boom!!

First, there was an attack that came from directly in front of Tiamat.

Quetzal Koyatl.

"Aha! Enjoy this South African-style wrestling attack—!!"

Quetzalcoatl yelled as he suddenly hooked his right foot, which was kicking Tiamat in the forehead, up.

Although its power was not as great as Yan Ming's output just now, it still managed to restrain Tiamat in her dragon form for a moment.

At the same time, completely different streams of light attacked from the left and right sides respectively.

Those are Ishtar and Ereshkigal.

Two goddesses, one wielding a radiant light like Venus, and the other holding a glowing spear, unleashing a torrent of lightning.

Boom—!!

Lightning and golden light struck Tiamat's wings, halting her flight the moment she was about to take off.

"Even though I have absolutely no idea what's going on, I at least have to defeat this guy now, right? Hey, Ereshkigal! Hurry up and give me the blessing of the underworld! That way, I can kick this guy away with one kick!"

"You make it sound so easy... I've already clearly sent the blessing from the underworld to everyone!"

Even with the support and suppression of the underworld's power, it was still impossible to launch a particularly effective attack on Tiamat.

However, only one person can unleash the most effective attack in the entire game.

Bang--!!

The second time, Yan Ming set off directly.

With a flying kick that combined the power of three people, Tiamat was sent flying in an instant.

Within this enormous underground cavity, the Mother Goddess's body was suddenly thrown back for over ten kilometers, and even then, she could not stop.

But that alone is not enough to eliminate Tiamat.

"After transforming into a dragon, her strength became much greater than before."

Merlin spoke as he used a flower-like barrier to disrupt the newly emerging tide of chaos.

"Even Yan Mingjun, who was completely suppressed at the beginning, has fallen to this situation now... but this is not the most difficult problem to solve."

correct.

The real challenge, as expected, is Tiamat's infinite resurrection.

Boom—a tremendous sound came from behind again.

At this moment, everyone turned around.

The huge, horn-like protrusion directly lifted the ground beneath their feet.

"Senior, step back!"

Mashu immediately hugged Fujimaru Ritsuka and quickly stepped back.

Boom! Tiamat's body reappeared.

However, the other two looked over calmly.

"...Haidong, we came here to solve this problem, right?"

"This time the situation is a little different. Maybe we really will find ourselves in a situation where we can't kill them all no matter what we do?"

"That's hard to say."

As he spoke, Tsukasa Kadoya pulled out a card.

He then activated the drive mechanism at his waist.

"Saying discouraging things before even winning is not my style at all!"

"Ha...that's true."

Hai Dong Da Shu smiled upon seeing this.

The two people looked at each other and smiled at each other amidst the broken ground and mid-air.

then--

Two different cards were inserted into the gun and the belt, respectively.

"Transform!" ×2

"Kamen Ride! Decade!"

"Kamen Ride! Diend!"

The interplay of red and blue merges from 360 degrees in the form of a light panel.

After a flash of light, Tsukasa Kadoya and Daiki Kaito's bodies changed.

It transformed into a masked warrior clad in ornate armor.

"Eh...?"

"Are you kidding me?!"

Mashu and Fujimaru Ritsuka were both surprised when they saw this.

Dr. Roman, far away in Chaldea, stared wide-eyed in astonishment.

"Those armors with extraordinary power, these two people who came from who-knows-where can also use them!"

As soon as they landed, the magenta and dark blue shadows took different actions.

First, Tsukasa Kadoya launched a direct attack.

He took out a weapon that resembled a card case from his waist, which transformed into a longsword. He wiped it with his hand and then suddenly leaped into the air.

Tiamat stared at him, then unleashed an endless tide of magical energy straight ahead.

boom--!
