Saber and Blades! The Best Duo!

Rin: "Here we are. Only a Sacred Sword grants passage between worlds."

Artoria and Rin stood before a towering blue book, its pages fluttering with ethereal energy.

Artoria: "We just… walk through?"

Rin: "Precisely."

Without hesitation, they stepped into the book. It snapped shut behind them, vanishing in a swirl of light.

{Story World – Distorted Cityscape}

Artoria: "What happened here...? These buildings are falling apart!"

Rin: "It's worse than I thought. The abnormalities are accelerating. This world is nearing collapse."

The buildings within the small world are decaying with bubbles flying around the place.

Rin: "Leave this to me. I'll show you how to fight." She stepped forward, unfastening her Seiken Swordriver and strapping it around her waist.

She retrieved a blue Wonder Ride Book, opening it with practiced ease.

SEIKEN SWORDRIVER!

Rin: "In the name of Nagare, the Sword of Currents... I will keep this world free from harm's reach."

She takes out a blue Wonder ride book and opens it.

"This blue mane records anew the wars of a noble king."

The book glowed as it is slotted into her driver, flipping open with a shimmering wave of light. Rin was suddenly surrounded by a library suspended in water.

Lion Senki!

She grips the handle of her Sword Nagare and pulls it out of the driver opening the ride book.

Nagare Battou!

Rin: "Henshin!"

A single, graceful slash tore through the air. A spectral blue lion surged from the open book, spiraling around her as crystalline armor formed across her body. The slash became her visor, completing the transformation.

Lion Senki! Nagare: Volume 1!

"When the king of the wilds and Nagare, the Sword of Currents unite, the azure blade shall barely its fangs! Nagare, the Sword of Currents!"

Artoria: "Whoa..." Her eyes widened in awe. "That's... incredible."

Rin (smirking): "Watch closely. This is how a swordsman fights."

The Ari Megid screeched and spat a stream of acid. Rin raised Nagare, slicing through the projectile mid-air as the acid sizzled against the ground.

Artoria ducked, just narrowly avoiding a splatter that melted through concrete behind her.

Rin: "Back off!"

She unleashed a swirling torrent of water from her blade, striking the Megid head-on and launching it backward. It snarled and rose, summoning foot soldiers—Shimi.

The insectoid creatures swarmed Rin.

Rin: "So it begins..."

Her blade danced through the enemy ranks, every movement fluid and precise. The Shimi fell one by one in flashes of blue light.

Rin: "An Ant Megid... I expected a swarm. And here they come."

Two more Megid emerged—grotesque and armored—flanked by more Shimi soldiers.

Rin: "Perfect."

She leapt into the air. Her Ride Book flipped open again.

Rin: "Lion Wonder!" Rin surrounds herself with water and delivers a water-enhanced slash that summons Lion Senki, which rams into the small army of Megido.

Artoria: "Amazing..."

Rin landed gracefully, spinning her sword.

Rin: "And that's just one way to fight. Learn well."

Artoria: "You made that look easy."

Rin: "Of course it was! This is just one way to fight, hopefully you'll learn something from this."

Artoria: "I had a feeling that you were strong, you finished that in no time."

Rin: "You aren't too bad yourself, I saw you fight that fallen angel last night. But I'm afraid it isn't over yet."

Artoria turned and spotted civilians trapped in a crumbling building. Without hesitation, she ran to them.

Artoria: "Everyone out—now! I'll hold them off!"

She strapped her Swordriver around her waist.

SEIKEN SWORDRIVER!

Drawing her Wonder Ride Book, she opened and inserted it into the driver.

Brave Dragon!

The book flipped open, a massive crimson dragon flaring to life behind her, flames bursting into the air.

She unsheathed Rekka.

Rekka Battou!

A red dragon comes out of the giant book behind her and flies around.

Artoria: "Henshin!"

Brave Dragon!

She spun her blade, unleashing two fiery slashes in the shape of an X. The dragon coiled around her, forming her armor in a fiery whirlwind.

Volume I! When the brave Dragon and Rekka, the Sword of Flames unite, the crimson blade shall pierce through all that is evil!

Rekka, the Sword of Flames.

Artoria: "Let's go!"

The Shimi lunged. Artoria clashed with them, blade against claw. Acid spit flew her way, and she rolled to dodge.

Artoria: "No more games!"

She tapped her Wonder Ride Book again. The pages flipped wildly as a second giant Brave Dragon book appeared behind her.

Dragon Wonder!

Artoria's body flared with heat as flames surged from her blade. With a fiery punch, she launched a dragon-shaped inferno that swept across the battlefield—incinerating the entire wave of Shimi in a spectacular explosion.

Rin: "Not bad, Saber. You're handling Rekka well."

The two Riders regrouped and began escorting survivors to safety.

The Queen Ari Megid returns and beside her, a towering mantis-like figure—the Kirigirisu Megid.

Kirigirisu Megid: "Humans... always scrambling. Always resisting."

Rin: "So there's the real puppet master."

Kirigirisu Megid (mocking laughter): "Struggle all you like. This world is rewriting itself—one page at a time!"

It pointed to a glowing book embedded in its chest.

Artoria: "That book... it's writing itself?!"

The two Megid vanished into the chaos, retreating before the Riders could give chase.

Rin: "Tch—cowards!" She was about to pursue when Artoria stops her.

Artoria: "Wait! Someone's hurt!"

She rushed to a blonde girl lying unconscious nearby.

Artoria: "Miss, are you alright?!"

Rin knelt beside her and checked for signs of life.

Rin: "She's breathing. Just unconscious. We need to get her out of here."

She looked at Artoria and nodded.

Rin: "Let's bring her back to the Northern Base. We need answers... and time to regroup."
