[ Atlas Academy Secure Laboratory ]
The lab was in complete disarray.
Monitors sparked and flickered as the Ark's presence invaded the systems.
Scientists and engineers scrambled to restore order, their frantic movements overshadowed by the growing pulse of red energy emanating from the Forceriser.
Suddenly, the lab door slid open with a hiss, drawing all eyes to the figure in the doorway.
Akira entered the room, his steps measured, his voice carrying the haunting melody of his earlier tune.
The red glow of the Forceriser pulsed in rhythm with his steps, an ominous synchronization that silenced the frantic crowd.
Akira: (smirking) "Looks like someone's been having a little trouble keeping things in line."
His casual demeanor sent a shiver through the room.
The lead scientist, a wiry man with sweat-soaked glasses, stepped forward hesitantly.
Scientist: (stammering) "Y-You! How did you—?"
Before he could finish, Akira raised his hand, revealing the Forceriser he got from Penny now clasped firmly around his waist.
The device's rugged design caught the dim light, its jagged edges and exposed cables giving it a raw, unstable appearance.
Akira: (mocking) "Oh, don't mind me. Just here to pick up what's rightfully mine and besides I'm just a passing through Kamen Rider."
With deliberate precision, Akira revealed the Japanese Wolf Zetsumerisekey, the device humming faintly as he activated it.
Japanese Wolf Zetsumerisekey: [ Japanese Wolf ! ]
The scientists backed away, their faces pale with fear. Akira's smirk widened as he slid the Zetsumerisekey into the Rise Vice.
The lab was filled with the sound of an industrial siren accompanied by a heavy drumbeat—a deafening signal of the transformation to come.
Akira: (calmly) "Henshin."
With a sharp pull of the Force Executor, the Zetsumerisekey snapped open, stopping the siren abruptly.
The Forceriser whirred to life, and an intense cold wave burst forth.
Frost coated the lab's walls and equipment as an ice storm swirled around Akira, enveloping him in a blizzard of data fragments and mechanical components.
Forceriser: [ Forcerise! Japanese Wolf! Break Down! ]
The transformation was violent, cables lashing out and securing pieces of armor to his body.
The jagged, wolf-themed helmet snapped into place, its blue visor glowing brightly as the process completed. The storm dissipated, revealing Akira clad in the sleek yet menacing armor, his form radiating an aura of cold precision.
Without hesitation, Akira launched into motion. His claws extended, a blur of movement cutting through the air.
The scientists and engineers fell one by one, incapacitated with terrifying efficiency.
In under a minute, the room was silent save for the faint hum of the Ark's influence dominating the systems.
Akira approached the central console, placing his hand on the Forceriser they have connected to their system
A sharp surge of electricity coursed through him as his consciousness linked with the Ark.
[ Ark Interface ]
The world around Akira shifted into a virtual expanse of crimson and black.
He stood in a swirling digital void, symbols and glyphs flickering in the distance.
A massive, ominous figure materialized before him—a construct of the Ark's will.
Ark: "Welcome back the systems are under our control. The stage is set."
Akira: (grinning) "Took you long enough. What about the others ?"
Ark: "The remaining members of MetsubouJinrai are securing Winter Schnee. Her escape would disrupt the final phase. Their location has been uploaded to you. Proceed and ensure they succeed."
Akira closed his eyes briefly, processing the data being streamed directly into his mind. A faint smirk returned as he reopened them.
Akira: "Got it. And what about Ironwood? He's bound to get involved sooner or later."
The Ark's presence pulsed.
Ark: "Ironwood is a pawn. Let him act. His desperation will only hasten his downfall. Focus on the plan."
Akira nodded, his smirk fading into a more focused expression.
Akira: (calmly) "Understood. Time to make this world feel the weight of extinction."
With a final surge of red energy, the interface dissolved, and Akira's consciousness returned to the lab.
[ Laboratory ]
Akira opened his eyes, the glow of the Japanese Wolf helmet flickering briefly.
The Ark's directive burned clearly in his mind. He stepped over the unconscious bodies of the lab workers, his claws retracting as he moved toward the exit after retrivng the Forceriser and Sting Scorpion Progrisekey
Akira: (to himself) "Amethyst, Adam, Onyx… don't screw this up."
He vanished into the shadows, his presence cold and lethal as the storm he had unleashed with a speed unknown to Akira he just passthrough the Aurora Curtain
[ Mantle – Streets of Chaos ]
The scene was chaos. The streets of Mantle teemed with panic as Grimm swarmed the city.
Civilians ran for cover, their screams blending with the blaring of security sirens and the ominous growls of the Grimm.
The giant screens in the square displayed Jacques Schnee's acceptance speech, his smug voice a dissonant backdrop to the destruction.
Jacques: "And as the newest member of the Council, I pledge to serve each and every citizen of Mantle and Atlas."
Above the chaos, Tsukasa Kadoya stood on a rooftop, his twin-lens camera in hand.
He snapped a picture of the shattered moon in the sky, then turned his attention to the swirling mist of the Aurora Curtains he had summoned moments ago.
Tsukasa: (examining a photo of Akira in his Forceriser armor)
"Interesting... Could this world's Zero-One be a variant of the main one? Or maybe something worse? Either way..."
He glanced at the destruction below and smirked.
Tsukasa: "Looks like I'll need to meet the locals. Maybe they'll tell me more about this world of 'Remnant.' Though that moon is a bit too broken for my liking."
Pocketing his pictures, he walked toward the edge of the rooftop, pondering his next move.
[ Mantle – Emerging from the Aurora Curtains ]
Akira stumbled as he emerged from the Aurora Curtains, shaking his head to clear the disorientation.
He looked around, quickly realizing he was now in the heart of Mantle, surrounded by chaos. The sound of wings flapping drew his attention upward.
Above him, several Manticores—a type of flying Grimm—descended on the city, their claws glinting in the dim red light.
Akira activated his armor's integrated weapon system, the cold glow of his Japanese Wolf armor.
Akira: "Tch. No rest for the wicked."
Before he could engage, he spotted a group of familiar faces rushing out of an alley to confront the Grimm.
Ruby: (pointing to the Manticores) "We have to stop them before they hit the shelters!"
Nora: (cracking her knuckles): "Finally! Some action!"
Ren: (calmly readying his weapons) "Stay focused until backup arrives.
Marrow: (calling to his team) "Let's keep the collateral damage to a minimum. Move!"
The four charged into battle, their weapons clashing against the Grimm.
Akira observed for a moment, then smirked beneath his helmet.
Akira: "Well, this isn't my fight, but... guess I'll lend a hand. For now."
With a burst of speed, Akira joined the fray, his armor gleaming as he slashed through a Manticore with chilling precision.
The sudden intervention shocked Ruby and the others.
Ruby: (staring in surprise) "Wait... isn't that—?!"
Akira: (calmly, while cutting down another Grimm)
"We'll settle our differences later. Right now, this city's under attack, and backup isn't coming anytime soon."
Nora: (blinking) "Did... did he just—?"
Ren: (frowning) "Focus! He's helping for now. Keep fighting!"
Marrow: (gritting his teeth) "This guy again... Fine. We'll deal with him after we clear these streets."
Akira dashed past them, the claws of his armor glowing as he tore through another wave of Grimm.
His movements were swift and calculated, his voice cutting through the chaos like a blade.
Akira: "I'm just a passing-through Kamen Rider"
Ruby: (determined, snapping out of her shock)
"Alright, everyone! Let's push them back!"
As the battle continued, the group fought side by side, though the tension between Akira and the others was palpable.
Above them, the giant screens still displayed Jacques' speech, his words drowned out by the roars of the Grimm and the clash of weapons.
[ Meanwhile on the rooftop ]
From another rooftop, Tsukasa watched the battle unfold, his expression one of mild amusement.
Tsukasa: (chuckling) "Now that's interesting. A Rider playing hero in a world like this... Guess it's time to introduce myself properly."
He reached for the NeoDecadriver at his waist, the familiar magenta glow emanating as he prepared to transform.
Tsukasa: "Let's see if these 'heroes' can tell me what I need to know but more importantly who do I help this worlds Rider or the colorful bunch of well.
[ Kamen Rider Decade OST: Henshin ]
Tsukasa: (Flipping a Rier Card ) "Henshin."
