“Summon Vent - Blastoise!”

As the cold electronic sound echoed through the silent Mirror World.

Rumble!!!

As if appearing out of thin air, a suffocatingly massive shadow enveloped the battlefield below.

The dark blue giant turtle landed steadily in the middle of the street, its heavy body causing the ground to tremble slightly.

The thick armor covering its entire body gleamed with a metallic, cold luster, and huge cannons extended from both sides of its shell, their muzzles deep and now emitting a dangerous, aquamarine glow.

Contract Beast Form - Blastoise!

“Roar?!”

Dragreder, who had just struggled to his feet from the architectural rubble, suddenly looked up, his crimson Dragon eyes fixed on the newly appeared giant beast, letting out a roar mixed with anger.

On the rooftop, You Hong's voice came through his faceplate, carrying a hint of ease under absolute control: “Water beats Fire, a common sense even kindergarteners know, right?”

He seemed to be speaking to the turtle, or to the Dragon, or even more, explaining to the two stunned spectators below.

The moment his voice fell, Blastoise moved!

No command was needed, the instinct for battle drove it.

The huge cannons suddenly dipped, and the eerie blue light rapidly compressed and condensed in the muzzles; the surrounding air seemed to become thick and heavy due to the gathering of water vapor.

“Roar—!” Dragreder felt a fatal threat and furiously opened his huge mouth, crimson flame energy also beginning to gather wildly! He wanted to strike first!

However, his speed was ultimately a bit slower.

Boom—!!!

A thick, azure beam of high-pressure water, carrying the violent might to crush everything, roared out from Blastoise's cannons.

The air was instantly torn apart, emitting a piercing shriek.

The power of this Hydro Pump far exceeded the one that had just knocked him down.

“Ow—!!!”

Dragreder only managed to let out a shriek of terror before the freshly condensed flames were instantly extinguished by the furious water stream.

The Hydro Pump, containing terrifying kinetic energy, slammed squarely onto his massive Dragon body!

He could only passively resist the overwhelming Hydro Pump.

But Blastoise's bombardment did not stop.

Rumble rumble rumble—!!!

Dragreder, like a huge red sandbag, was pushed by the Hydro Pump and slammed irresistibly into a taller office building in the distance!

The entire building at the impact point suddenly caved inward and twisted.

The glass curtain wall shattered over a large area like fragile ice crystals, countless fragments mixed with concrete blocks pouring down like heavy rain.

Smoke and dust mixed with dispersed flame steam instantly rose into a massive mushroom cloud!

The earth trembled!

Just one strike!

The terrifying giant Dragon that had been chasing two Knights just moments ago was now embedded in the crumbling building like a dead dog, only intermittent, pained, and weak whimpers remaining.

Silence.

The Mirror World seemed to have had its mute button pressed.

There was only the groaning of the building's remains, unable to bear the weight, and the faint “hissing” sound of white steam slowly dissipating from Blastoise's cannons in the distance.

Kido Shinji's mouth hung open, his jaw almost dropping to his chest plate.

He looked at Dragreder embedded in the building, then at the platinum Knight on the rooftop who was casually clapping his hands, his heart filled with shock.

“So… so powerful…” Kido Shinji's voice was dry, “He he he… who exactly is he?! Why can he summon such a big turtle?! And possess such power?!”

Akiyama Ren turned his head, his dark blue compound eyes glaring at the idiot beside him who was still marveling at the “power.”

A surge of nameless anger instantly rushed to his head.

“Shut up! You idiot!” Night Knight's voice came through his faceplate, “Don't you even know what you're participating in?!”

“Par… participating?”

Kido Shinji flinched from the shouting, “Participating in what? Who's participating? I just wanted to save people! I inexplicably got this box, inexplicably got dragged in, and inexplicably almost got killed… Hey! Mr. Dark! Why are you so fierce! If you know something, just say it!”

“Idiot! Of course it's…” Akiyama Ren was so angry he almost made a move, but he was interrupted by the voice from the rooftop.

“He really doesn't know anything, you know.”

You Hong's voice drifted down lightly, with a hint of playfulness.

He slowly leaned half his body out from the rooftop, waving to the ground below.

Akiyama Ren's fists clenched, cracking, and the expression under his helmet was probably so dark it could drip ink.

To be rescued in an overwhelming manner by a mysterious guy, and then to have this mysterious guy expose that he didn't even know his opponent's background… this feeling was terrible.

In the center of the battlefield, filled with mist and smoke, You Hong slowly put away his spectator's pose.

His gaze swept over Dragreder, struggling in the embedded building, and he had already made up his mind.

Let's end this quickly!

The Summoner on his left wrist glowed faintly again, and a new card appeared between his fingers—the background color was still a deep ocean blue.

It depicted Blastoise with its cannons fully open, condensing destructive energy.

Click.

The card was cleanly and decisively inserted into the slot.

The blue light on the Summoner's dial instantly surged!

Even more dazzling than when he was summoned just now!

“Final Vent!”

The cold electronic voice announced again.

Blastoise's huge cannons suddenly lifted.

Inside the muzzles, water-attribute energy compressed to the extreme emitted a heart-pounding fluctuation, the blue light so dazzling it was like a small sun!

“Hydro Cannon!”

Hum—boom!!!!!

It was no longer a water column, but a highly condensed, deep blue beam, far exceeding the previous one in diameter, as if piercing through heaven and earth!

It tore through the pervasive smoke and mist, carrying the absolute power to destroy everything, instantly traversing space.

Target—Dragreder!

“Roar—!!!”

Dragreder let out an angry wail.

He wanted to struggle, wanted to escape, but his massive body was embedded in the ruins, with nowhere to run.

The deep blue beam slammed into his Dragon body.

Causing a huge explosion.

Just as everyone thought the outcome was decided, a Dragon roar came from the smoke of the explosion, and then a Dragon shadow shot out from the smoke, flying away without looking back.

Dragreder, as expected of a Dragon Mirror Monster.

Even after all that, he still had the stamina to escape.

When the smoke cleared.

Only the building with a huge hole pierced through it, and the residual water vapor in the air, testified to the horror of that last move.

And seeing his opponent escape, Blastoise nodded.

His massive figure also transformed into specks of blue light, disappearing without a trace.

The Mirror World once again returned to its suffocating silence.

Water mist lingered, and smoke had not yet dispersed.

You Hong stood at the edge of the rooftop, his platinum armor reflecting a cold, hard sheen in the sparse light.

He looked down at the two Knights below, completely stunned by this ultimate strike.

The easy, teasing tone was gone, replaced by a calm, almost cold statement.

His voice was not loud, but it clearly penetrated the space, striking hard at Kido Shinji's heart:

“Listen well, kid.”

“This place you inexplicably stepped into.”

“Is the Kamen Rider War.”

“Taking others' lives, seizing others' hopes, trampling on others' happiness…”

“All just to…”

“Fulfill your own wish.”

You Hong's gaze seemed to penetrate Kido Shinji's armor, seeing through to Kido Shinji's essence.

The last few words carried a heavy weight, like a pronouncement:

“Remember this!”

“If you don't fight…”

“You won't survive.”
