The battle in the Wonder World raged on as Rin, the blue swordsman Kamen Rider Blades, and Artoria, the flame-wielding Kamen Rider Saber, continued their desperate fight against the Hanzaki Megid. The creature's regenerated body proved far tougher than before. Each time their swords struck its body, the blades slid off as if they were striking hardened stone rather than flesh.
Sparks flashed with every impact, yet the Megid barely staggered. It snarled and swung its chainsaw-like sword wildly, forcing the two Riders to keep their distance while searching for an opening.
Realizing brute force alone wouldn't be enough, Rin tightened her grip on her Seiken. "Artoria, let's switch to elemental attacks this time!" she called out while shifting her stance.
Artoria nodded immediately. "Right!"
Rin swung her blade in a wide arc, releasing a crescent wave of water that surged toward the Megid. At the same moment, Artoria followed up with a blazing slash from Kaenken Rekka, sending a burst of fire racing alongside Rin's attack. The twin elements collided against the Hanzaki Megid, splashing flames and steam across the battlefield. Seizing the moment, the two Riders leapt into the air together and attempted to finish the assault with simultaneous kicks.
However, the Megid reacted faster than expected. With a violent roar it swung its sword upward, striking both Riders' armor. Sparks burst outward as the attack connected, knocking the two back and forcing them to land hard on the ground.
Rin steadied herself and studied their opponent carefully. "Its power has increased substantially,"
Artoria, breathing heavily, dropped to one knee and used Rekka to support herself. Even so, determination burned in her eyes. "Rin-senpai… we can use up to three Wonder Ride Books, right?"
Rin blinked in surprise at the sudden question. "Well… yes, that's correct, but why are you ask—"
Before she could finish, the Hanzaki Megid charged straight toward them with its sword raised. The two Riders quickly rolled aside to evade the strike, the blade slamming into the ground where they had just been standing.
Artoria sprang back to her feet with a grin. "Cool! I'll take that!"
Before Rin could react, Artoria reached over and pulled the Peter Fantasista Wonder Ride Book from Rin's Swordriver. With the removal of the book, Rin's transformation destabilized and she reverted back to her base form Lion Senki.
"Hey! What exactly are you planning now?!" Rin protested in disbelief.
Artoria ignored the complaint and quickly closed both the Brave Dragon and Needle Hedgehog books already set in her driver. "If two volumes weren't enough, maybe three will give us a fighting chance!" she said confidently before flipping open the new book.
PETER FANTASISTA!
She slid the blue Wonder Ride Book into the third slot of her Swordriver and drew Kaenken Rekka from the driver. As she did so, all three books burst open simultaneously, their pages flipping rapidly with brilliant energy.
REKKA BATTOU!
Artoria appeared within a blazing library filled with towering shelves and roaring flames.
When the power of three books combine, the sacred sword shall brim with strength!
The spirits of the three stories emerged—Brave Dragon, Needle Hedgehog, and a glowing green fairy from Peter Fantasista. They circled Artoria as power surged through her body. Her left arm transformed, now covered in sleek blue armor equipped with a new weapon: the Capture Hook, a chain device capable of ensnaring enemies and pulling them into striking range.
WONDER RIDER!
Back in the battlefield, Artoria immediately tested the new power. She launched the Capture Hook forward, the chain wrapping tightly around the Megid's chainsaw blade. Using the tether as leverage, she yanked the weapon aside and delivered a powerful kick to the creature's stomach, followed by a swift spinning kick that slammed into its chest.
DRAGON! HEDGEHOG! PETER FAN!
"So this… is the power of three books…" Artoria murmured, feeling the tremendous energy coursing through her armor.
With the power of three attributes dwelling within, the mighty blade descends upon the world!
From a distance, Issei and Sora watched the transformation in awe as the red Rider's new form stood proudly before the monster.
The Capture Hook snapped back into her gauntlet as the Megid collapsed onto the ground, sparks bursting from its damaged body. It struggled to stand, but golden spikes erupted from within its body and detonated violently, forcing it down to its knees.
Watching from nearby, Rin folded her arms in disbelief. "Huh… what a strange way of fighting."
Despite its injuries, the Hanzaki Megid roared defiantly. "I refuse… I will not lose to the likes of you!"
The creature charged again, attempting to strike Artoria from behind. Without even turning around, she spun on one foot and delivered a lightning-fast roundhouse kick that smashed into the side of its head, sending the Megid crashing into the ground.
Artoria faced the fallen monster with unwavering resolve. "I'll decide how this story ends. I won't let you hurt anyone else." Her voice hardened as she raised Rekka. "My duty is to protect those who cannot protect themselves!"
FINAL PAGE!
Behind her, giant projections of the three Wonder Ride Books appeared in the sky.
DRAGON HEDGEHOG! PETER FAN!
Artoria summoned a glowing turquoise fairy projection. The magical figure flexed playfully before grabbing the Capture Hook, spinning rapidly as flames from Brave Dragon engulfed it.
THREE VOLUMES STRIKE!
F-F-F-FIRE!
Artoria hurled the fairy forward like a blazing comet.
"Good… riddance!" she shouted.
The fairy slammed into the Hanzaki Megid, pinning it to the ground before blowing a cheeky kiss. A moment later it exploded into a massive burst of golden hedgehog quills that tore through the monster.
When the smoke cleared, the Hanzaki Megid was gone.
The transformation faded as Artoria returned to her school uniform, with Rin also dehenshining beside her.
"That… that was amazing!" Sora exclaimed as he ran over with Issei close behind.
Artoria knelt down slightly. "Are you okay, Sora?"
"Yeah! That was awesome!" the boy replied happily.
Rin crossed her arms while glancing at Issei. "We actually found you because of that strange green light earlier."
Artoria nodded and pointed at Issei's arm. "Speaking of that… what's that on your arm?"
Issei looked proudly at the small red gauntlet with a green jewel and two golden spikes. "This? I finally summoned my Sacred Gear!" he said with a grin. "Though… I'm not really sure what it does yet."
"I'm sure you'll figure it out eventually," Rin said reassuringly.
Moments later, the Wonder World began to dissolve around them. Issei and Sora vanished, returning to their original locations. Sora reappeared in the park and immediately ran toward his father.
"Father!"
"Sora!" Ogami embraced his son tightly. Relief washed over him as he realized the boy was unharmed. That girl truly kept her promise, he thought with quiet gratitude.
Back in the fading Wonder World, Artoria stretched her arms and smiled at Rin. "Looks like our first mission together went pretty well, right?"
Rin returned the smile. "Yeah… I think it did."
Suddenly, Artoria staggered. The immense strain of using three Wonder Ride Books at once finally caught up with her, and she collapsed onto the grass. Rin rushed to her side.
"Even veteran swordsmen would be exhausted after using three books at once," Rin explained while helping her sit up. "That was reckless… but I'll admit, it looked pretty cool."
Artoria laughed weakly. "Thanks, Rin. You're a pretty great teacher."
"Hmph! Of course I am!"
Their laughter faded when Rin noticed a new presence approaching. A dark figure stepped forward, a purple Kamen Rider clad in armor of darkness.
Artoria's expression shifted instantly. Something about him felt familiar.
"That… looks familiar," she murmured, recalling the mysterious warrior she had seen in her dreams. "The swordsman I saw…"
Far away in the North Pole, Sophia suddenly sensed the disturbance.
"The swordsman of darkness…" she whispered.
Back in the Wonder World, the purple Rider drew his blade.
Artoria and Rin quickly transformed again, but their opponent was far beyond their strength. Within moments Artoria collapsed, her transformation breaking under exhaustion.
"He's… so strong…" she gasped.
The dark Rider pointed his sword at her.
"Hand over the Sword of Flames and the Brave Dragon."
He pulled the trigger on his weapon.
KURAYAMI QUICK-DRAW!
Dark energy surged into the blade as he unleashed a massive purple slash.
ENDING FLASH!
Just as the attack was about to strike, a bolt of blue lightning shot down and blocked it.
Artoria looked up in shock.
Standing before them was Kay, transformed into Kamen Rider Espada, his lightning blade crackling with energy.
The mysterious dark Rider suddenly vanished, transported away to another location where he silently looked down upon the Wonder World below.
