Kanzaki Yui Under Attack

"Auntie, I'm going out."

"Alright, come back early."

Kanzaki Yui waved her hand, leaving the Flower Chicken Cafe. Today, she planned to go shopping.

However, as she left, she didn't notice Tojo Satoru, the waiter in the shop, watching her with a changed expression.

Walking alone on the street, Kanzaki Yui was in a good mood. Suddenly, something seemed to flash and disappear in the corner of her eye, and she abruptly stopped.

"Just now was..."

Kanzaki Yui's expression changed. She looked left and right. The street was sparsely populated; the nearest person was dozens of meters away.

What was it?

Kanzaki Yui suddenly thought of something and quickly moved away from the crystal wall beside her, but it was already too late.

A black armored arm reached out, grabbed Kanzaki Yui's arm, and pulled her into the Mirror World.

"Ah!"

Kanzaki Yui showed a pained expression, falling directly to the ground. A black figure appeared before her eyes.

"You are?!"

The Kamen Rider armor was completely different from Kido Shinji's and the others'. It was entirely black, and the design of the Rider Card Box at its waist was also completely dissimilar; no similarities could be seen.

This was a newly appeared Kamen Rider, and most likely not created by Kanzaki Shiro.

"What do you want?!"

The mysterious Rider drew a card from the Rider Card Box, swiped it across the summoning device on his left wrist, and it transformed into a blue flame, disappearing.

"Sword Vent"

A cluster of blue flames appeared in his right hand, and a strange longsword emerged, shaped like a centipede with sharp spines protruding from each joint. He gripped it and immediately, without hesitation, slashed towards Kanzaki Yui.

But just as the mysterious Rider was about to succeed, a GuldStorm, identical to GuldThunder, suddenly charged out, knocking the mysterious Rider away and shielding Kanzaki Yui.

"Monster... It's Brother!"

Kanzaki Yui suddenly turned her head and indeed saw Kanzaki Shiro appear behind her.

"Brother!"

"Yui..."

Kanzaki Shiro's gaze shifted to the mysterious Rider, his face showing unconcealed killing intent.

"Kill him."

GuldStorm, holding its battle-axe, roared and lunged at the mysterious Rider. The two exchanged a blow, resulting in a stalemate.

At this moment, several Gigazelles suddenly rushed forward at extreme speed, and immediately DarkWing, clinging to Akiyama Ren's back, descended from the sky.

Seeing Akiyama Ren arrive, Kanzaki Shiro directly left. Kanzaki Yui stood up and chased after him, but after turning a corner, he was gone. On another battlefield, GuldStorm and the Gigazelles also disappeared one after another. Only two Kamen Riders remained in a standoff.

"Who are you?"

"Sword Vent"

Akiyama Ren pointed his Dark Wing spear directly at the mysterious Rider, his tone unfriendly.

But the opponent said nothing, directly attacking Akiyama Ren.

Akiyama Ren, seeing this, met the attack without weakness.

Kanzaki Yui watched this scene, bewildered and flustered.

But not long after, Takeshi Asakura, transformed into Kamen Rider Ouja, also arrived at the scene, followed by Tsuhachi Yonemura, transformed into Kamen Rider Crocochilus, and then Hozer, riding FrostWolf, also caught up.

Takeshi Asakura, without a word, directly joined the battle. Akiyama Ren and the mysterious Rider continued to fight. Tsuhachi Yonemura, however, felt a sense of retreat; he felt that all of this was strange, as if they were intentionally led here.

Hozer walked over to Kanzaki Yui and asked, "Yui, why are you here?"

"That Rider pulled me in."

Hozer felt a slight shock in his heart, looking at the mysterious Rider in the chaotic battle.

A Kamen Rider with a completely different style from theirs, who dared to attack Kanzaki Yui, seemed not to be created by Kanzaki Shiro, and his hostility was undeniable.

Looking at the Kamen Riders in the arena, besides Kanzaki Shiro, no one else could have led them here.

"Yui, how long have you been here?"

"A few minutes."

Kanzaki Yui also thought of something, saying uncertainly.

A few minutes... An ordinary person waiting in the Mirror World would dissipate into particles in less than five seconds. Kanzaki Yui waited so long without any abnormality; the Mirror World was indeed greatly related to her.

"Yui, I'll take you out first."

"But..."

"Leave these matters to us."

With that, Hozer said no more, pulled Kanzaki Yui out of the Mirror World, then de-transformed and guarded her, preventing anyone else from harming her.

Turning his head to look at the mirror, after Hozer left, Tsuhachi Yonemura also joined the battle. Although Takeshi Asakura fought anyone, Akiyama Ren and Tsuhachi Yonemura had a unified goal, and the mysterious Rider quickly couldn't hold on, defeat was only a matter of time.

But at this moment, a sound suddenly rang out.

"Final Vent"

Everyone fighting stopped, wary of each other. At this moment, a giant white figure charged towards Tsuhachi Yonemura from the darkness.

Tsuhachi Yonemura was startled. Unable to dodge, he was directly knocked to the ground, then grabbed by sharp claws on his chest and rapidly dragged across the ground.

It was a bipedal tiger-shaped contract monster, entirely white — Destwilder.

At this moment, everyone present realized that a new Kamen Rider had appeared not far away, holding two giant tiger claws in his hands, gathering strength, waiting to attack.

Seeing Tsuhachi Yonemura about to be finished, he suddenly kicked, sending Destwilder, who was dragging him, flying. After sliding a few meters, Tsuhachi Yonemura barely managed to stop.

Hozer frowned slightly, immediately pulling out his Rider Card Box.

"Hozer, no need!"

Kanzaki Yui cried out, reaching out but unable to grasp Hozer's sleeve.

"Henshin."

Stepping into the Mirror World, Hozer pulled out a weapon card and inserted it into the wolf head summoning device.

"Sword Vent"

With the Wolf Head Devouring Blade in hand, Hozer quickly rushed towards Tsuhachi Yonemura, who was struggling to get up.

Using the momentum of his charge, Hozer thrust upwards, striking Tsuhachi Yonemura from the waist up, sending him flying with a single slash, slamming him hard into a pillar. When he fell, the Rider Card Box at his waist shattered on the spot.

"Ah, no!"

Tsuhachi Yonemura reached out and screamed, but the Rider Armor on his body rapidly dissipated, transforming him back into a normal human.

With a crash.

The ground not far away cracked open into a large pit, and Smilosuchus burst out, suddenly lunging at Tsuhachi Yonemura.

Before Hozer could act, Takeshi Asakura directly pulled out three contract cards, summoning Venosnaker, Metalgelas, and EvilDiver, to attack Smilosuchus.

In just a moment, Tsuhachi Yonemura dissipated into particles.

Hozer turned his gaze towards the newly appeared Kamen Rider Tiger.

Sneak attacks were not a favored behavior.

And this Kamen Rider before him was already the eleventh Kamen Rider on Kanzaki Shiro's side. It seemed he was another ruthless and decisive character.

However, the opponent voluntarily retreated. Hozer became even more curious about the identity of the mysterious Rider and did not pursue further complications.

That mysterious Rider also took the opportunity to escape. The Rider Armor on Akiyama Ren's body began to dissipate, and he also had to leave the Mirror World.

Finally, Smilosuchus was kicked to death by Takeshi Asakura, its life energy absorbed by Venosnaker.

Kanzaki Yui was temporarily out of danger. Akiyama Ren had caught up to her, and Kanzaki Shiro was still watching from the shadows. Hozer felt relieved and went to track the mysterious Rider.

In a nearby alley, Tojo Satoru and Hajime Nakamura emerged from the Mirror World, seen by Hozer.

"Hajime Nakamura..."

He silently followed the two to the sealed laboratory in the Seiinen University research building.

Hozer's expression became thoughtful. If he remembered correctly, this seemed to be the laboratory where Kanzaki Shiro had conducted experiments.
