37. A very Magenta Ark

[ Mantle ]

The frigid winds of Mantle sweep through the cracked streets, carrying whispers of lingering fear from the recent Grimm attacks.

Among the city, Riot strolls casually, his half-jester mask gleaming in the dim light of broken street lamps.

He twirls his Anotherwatch between his fingers, the faint glow illuminating the mischief in his eyes.

Riot: (mockingly)

"Ah, truly... A city on the edge of despair. So many broken toys to play with."

As he scans the area, his gaze locks onto the digital wanted posters on a cracked screen. The faces of Team RWBY and their allies flash before him.

Riot: (grinning under his mask)

"Interesting. Heroes always have a way of ruining good fun. Maybe I'll find one of you to make things more... entertaining."

Before he can act, the air grows tense. A faint shimmer forms in front of him, and a figure steps through the aurora curtain.

The man's confident stride and magenta-colored armor catch Riot's attention immediately.

Riot: (cocking his head)

"Well, you're certainly not from around here. Who might you be, interrupting my little stroll?"

The figure adjusts his himself, drawing his Ride Booker and holding it in sword mode. His voice is calm, yet carries an undeniable authority.

Tsukasa: "Just a passing-through Kamen Rider. Remember that!"

Riot pauses, his smile faltering briefly before returning with a sharp edge.

Riot: "Kamen Rider, huh? And what business does a 'passing-through' rider have with little old me?"

Tsukasa takes a step forward, his eyes narrowing beneath his helmet.

Tsukasa: "You're a Time Jacker. I don't need to know more. You're planning on tampering with a timeline that's already a mess."

Riot laughs, spinning his Anotherwatch like a toy.

Riot:

"Tampering? Oh, you wound me. I'm just adding a little... flair to this dull, broken world. What's a bit of chaos between friends?"

Tsukasa raises his sword, the air crackling with tension.

Tsukasa: "Save your excuses. I've seen enough destruction caused by your kind. I'll end this here."

Riot's grin sharpens, and he snaps his fingers. Time freezes around them—debris suspended mid-air, flickering streetlights locked in place, and fleeing civilians frozen in fear. Riot twirls his sword staff, pointing it toward Tsukasa.

Riot: "Impressive words, Rider. But can you fight when time itself bends to my will?"

To Riot's shock, Tsukasa takes a step forward, unfazed by the frozen time.

Tsukasa: "Time Jackers never learn. Your tricks don't work on me."

Riot's eyes widen briefly before narrowing.

Riot: (intrigued)

"Oh, you're a special one, aren't you? This might actually be fun."

Riot lunges, his sword staff spinning with precision. Tsukasa blocks effortlessly with his Ride Booker, the clash of their weapons sending shockwaves through the frozen world.

Riot: (laughing) "Not bad, Rider! But let's see how you handle this!"

He rewinds time by five seconds, repositioning himself behind Tsukasa for a surprise attack. Yet, as his blade swings, Tsukasa sidesteps smoothly, his movements calculated.

Tsukasa: "Your rewinds are predictable. I've fought stronger enemies with worse tricks."

Riot growls, slamming his staff into the ground and unleashing a wave of temporal energy.

The environment around them distorts, buildings flickering in and out of existence as time itself warps.

Riot: "Predict this, Rider!"

Tsukasa calmly pulls a Rider Card from his Ride Booker, sliding it into the NeoDecadriver.

NeoDecadriver: [ Kamen Ride: Kuuga ! ]

In an instant, Tsukasa's armor shifts, transforming into Kamen Rider Kuuga's form.

He charges forward, his punches now heavier and more precise, forcing Riot onto the defensive.

Riot: (gritting his teeth) "You're more annoying than I thought!"

Riot freezes time again, attempting another ambush, but Tsukasa counters with a Rider Kick that shatters the frozen stasis around them. Riot stumbles back, his mask cracking slightly.

Tsukasa: "Give up. You're outmatched."

Riot, panting, glances at his cracked mask in a nearby reflection. He tightens his grip on his staff, his grin returning.

Riot: "This isn't over, Rider. I'm just getting started."

Before Tsukasa can react, Riot disappears into a temporal rift, his laughter echoing through the empty streets.

Tsukasa: (lowering his weapon) "Fucking Coward."

As the world returns to normal, Tsukasa glances at the fleeing civilians and the wanted posters on the screen. He sighs, shaking his head.

Tsukasa: "This world is a mess. But I suppose it's worth calling more qualified people maybe Zi-O or Diend could come in and help me with this Pit stop world."

He steps into an aurora curtain, disappearing just as the first responders arrive at the scene. The fight is over, but the battle has only just begun.

[ Small Time Skip ]

[Mantle – Akira and Adam ]

The winds of Mantle whistle through the streets as Akira, Adam, and their battalion of six Trilobite Magia march through the area.

The mechanical footsteps of the Magia clank rhythmically against the shattered pavement, their glowing eyes scanning for threats.

Akira walks at the forefront, his long coat fluttering in the wind, while Adam, his cybernetic enhancements glinting in the dim light, walks beside him.

Adam: ( glancing at Akira ) "So, what's the grand plan, Akira? Besides making the Huntsmen look like idiots, of course."

Akira: (smirking, his eyes sharp as he surveys their surroundings)

"The plan, Adam, is to exploit their weaknesses. Mantle and Atlas are already crumbling under their weight. Salem's forces will only accelerate the process. Once the dust settles, we'll rebuild this place in our image."

Adam: (raising an eyebrow)

"Rebuild? And what makes you so sure that's even possible? Between Salem, the Grimm, and Ironwood's military, this place is a warzone waiting to happen."

Akira: (stopping in his tracks, turning to face Adam)

"It's not about possibility—it's about inevitability. The Ark has predicted their downfall.

Ironwood, the Huntsmen, and their little teams—Team RWBY, JNPR, the Ace-Ops—they're not just fighting Salem. They're fighting each other.

Distrust will tear them apart before we even need to lift a finger."

Adam: (crossing his arms, skeptical)

"And when they fall? What happens when Salem finally gets here?"

Akira: (grinning darkly, his voice cold)

"That's the beauty of it. Salem's forces are predictable. Chaos thrives in a vacuum, and that's where we come in.

By the time she sets her sights on Mantle and Atlas, we'll already have fortified key areas. Control the city, control the people."

Adam: (narrowing his eyes)

"And the Huntsmen? You think they'll just stand by and watch?"

Akira: (chuckling, resuming his pace)

"No. They'll fight. And they'll lose. Ironwood's arrogance will be his downfall, and the rest of them? They're too sentimental, too bound by their ideals to see the bigger picture."

The group reaches a strategic vantage point overlooking a series of Mantle's remaining outposts.

Akira signals for the Trilobite Magia to spread out and secure the area. Adam watches as the mechanical soldiers move with precision.

Adam: (after a pause, his tone quieter)

"You sound like you've already won."

Akira: (without looking back, his voice calm)

"Victory isn't about brute force, Adam. It's about patience. The Huntsmen don't realize it yet, but every move they make is just another step toward their own defeat."

Adam: (gripping the hilt of his Slashriser)

"Guess we'll see. But if we're going to take this city, I want to make sure the people who made me this way pay for it."

Akira: (turning to Adam, his expression unreadable)

"You'll get your revenge. But don't let it cloud your judgment. We're not here to settle personal grudges. We're here to reshape the future."

Adam: (smirking faintly, though his eyes remain cold)

"Fair enough. But don't expect me to show mercy."

Akira: (grinning)

"Mercy is for the weak yes but yet hear you are. Don't see it a weakness but rather a new path we just need a little push."

The conversation is interrupted by the sound of distant commotion.

A small group of civilians is being attacked by Grimm. Akira raises a hand, signaling Adam to stop.

Akira: "Let's make an example out of this. Show them what happens when order collapses."

Adam: "Gladly."

Akira watches with calculated interest as Adam and the Trilobite Magia descend on the scene.

The battle is swift and brutal, the rogue drones no match for their combined might.

As the civilians watch in a mix of fear and awe, Akira steps forward, his voice calm but commanding.

Akira: "Remember this moment. The Atlas military failed you. The Huntsmen abandoned you. But we… we will bring order to this chaos thats the Will of MetsubouJinrai net."

The civilians exchange uneasy glances but say nothing. Adam sheathes the Slashriser, his expression unreadable as he rejoins Akira.

Adam: (quietly) "You think they'll follow us?"

Akira: (smiling faintly)

"They don't need to follow us yet. Fear is a powerful motivator. When the time comes, they'll realize we're their only real option."

[ Amethyst and Onyx ]

The hum of computers and flicker of screens dominate the dimly lit server room of the Schnee Dust Company (SDC) delivery center.

Amethyst sits before a console, her slender android fingers a blur as she hacks into the company's mainframe.

Streams of data scroll across the screen as she methodically overrides security protocols. Onyx stands nearby, holding Akira's Terminal one hand and observing the room with his cold, calculating gaze.

Amethyst: (focused, her voice mechanical yet laced with satisfaction)

"Security protocols bypassed. I've gained control of 48% of the company's shares. Initiating the final phase to secure majority ownership."

Onyx: (glancing at her progress)

"Excellent. Once the Ark has full access to their systems, the SDC will be under our control. Akira's vision moves one step closer."

As the last of the security measures fall, Amethyst straightens, her glowing eyes locking onto Onyx.

Amethyst:

"Ownership of 52% achieved. MetsubouJinrai is now the majority shareholder of the Schnee Dust Company. Transferring all internal data to the Ark."

Onyx places Akira's terminal on the console and connects it to the mainframe. The laptop hums to life, and the screen fills with binary code interspersed with glowing red kanji.

The room darkens as the Ark's presence floods the system.

Ark: (through the terminal, its voice cold and resonant)

"Data acquisition complete. The SDC's operations, resources, and weaknesses are now fully integrated into my systems."

Onyx: (disconnecting the laptop)

"The Ark has what it needs. Proceeding to finalize the prototype."

He retrieves a small, black-and-red device from a compartment in his armor—a crude but powerful transformation belt with ominous kanji glowing on it's center.

As he holds it, the device pulses with malevolent energy, red and black lights flashing erratically.

Ark: "The prototype driver is now complete. Prepare for synchronization."

Onyx attaches the Ark Driver to his belt. The device immediately locks into place, the straps wrapping around his waist with a mechanical hiss.

The air grows heavy as the Ark's presence intensifies, its malice palpable.

Ark Driver: (announcing activation with a distorted, chilling voice)

Ark-Driver: [ Ark Driver ! ]

Onyx's body stiffens as the Ark takes control, his eyes glowing a deep, menacing red. His movements become fluid yet unnatural, every step precise and deliberate.

Ark (controlling Onyx): (his voice now a blend of Onyx's and the Ark's)

"This vessel is sufficient for the time being. Combat data must be gathered to ensure the final conclusion. Soon, Akira will become Ark-One, and MetsubouJinrai will achieve its goals."

Amethyst watches the transformation with an unflinching expression, her voice calm.

Amethyst:"All as the Ark wills it"

Ark: (turning to face her)

"The SDC's resources will fund our next operations. Mobilize the Trilobite Magia to more key locations. I will begin harvesting combat data immediately."

Onyx's body moves with eerie precision, lifting a hand as a surge of black and red energy ripples outward.

The entire facility shakes as the Ark's malice embeds itself into the systems, ensuring their absolute control.

Amethyst:

"Understood. I will oversee the deployment. The Schnee family will not recover from this blow."

The Ark nods, a chilling smile forming on Onyx's face.

Ark: "Excellent. The Huntsmen, Atlas, and even Salem herself will be no problem. All malice feeds the inevitable god. The world will bend to its will."

The room plunges into silence, save for the hum of machines.

Amethyst begins relaying commands, while Onyx, under the Ark's control, prepares for their next phase: total domination.

The world may not yet know it, but MetsubouJinrai has taken its first irreversible step toward rewriting its fate.
