Kamen Rider Geats: Back in Time

Geatskijouban I: Another World Wut?

(an:this takes place in the small time period between BulletDragon debut and the moment where the time portal appeared leading everyone to Japan)
(an: but also things about to be wild wild very wild, to the point where you should question whether this is canon, but it is)

Keiwa and Ayoko were walking on the cobble street after visiting the market.
"You have no idea how much I miss the normal life without monsters after whatever we went through" Keiwa sighed.
"Yeah, I know my wish will probably not become true without supernatural phenomenon but I'd rather have life as it is now" Ayoko replied, looking at the sky.

"Yeah! Yeah! Medieval~ World~"
Out of nowhere, a voice was echoed on the street. The two of them stopped and looked around.
Appear a female figure no older than a teenager, her eyes held a gleam of twisted genius that belied her youthful looks. Bright pink hair was cut short and messily styled, matching her eccentric style of dress - a mishmash of fantasy clothing pieces in clashing neon colors. In one hand she casually leaned upon an ornate staff topped with a glowing gem. But it was her piercing gaze that caught one's attention, eyes an unnatural swirling silver that seemed to glimpse into the corners of one's soul.
"Hey, who's that girl? her outfit is kind of weird," Keiwa asked Ayoko.
"Maybe person from another country?" Ayoko wondered.
Other than these two there were alot of people who also looked at the girl weirdly.
"Alright~ time to begin! Let's change this world!" With a toothy grin that was menacing and dangerous, the girl flourished her staff.
Countless monsters appeared and started attacking everyone, the monsters looked like Jyamatos, if they cosplay excessively: some of them look like swordsmen, fighters but most of them look like mages.
"What-" Keiwa kicked a Jyamato away before continuing "Thought we were done with this stuff!"
"Was not looking forward to using this but no choice!" Ayoko said.
"Henshin!"
[Set!] [Set!]
The Ninja logo and Fantasy logo appeared along with its swords.
The Ninja logo was hit by shurikens, the Fantasy logo shone. Both turned into upper armors and robot arms fitted the green Ninja armor to Koatycoon/Keiwa and the gold Fantasy armor to Tora-Go/Ayoko
The two of them fought together with agility, strength and skill. The monsters were taken aback by the ferociousness of Tora-Go and Koatycoon's teamwork, unable to withstand their powerful attacks.
"Ugh, get the hell out." The mysterious person held her staff up high and summoned lightning bolts to strike the Riders. Both were pushed back by its powerful force.
"This girl is no joke!" Keiwa shouted.

Ace observed from afar away, "What do we have here?" he grinned and slowly made his way to the girl.
"Hah~ he and she and now you?" the girl muttered.
Ace equiped his Driver.
[Set!] [Set!]
Bullet EX logo and Dragon logo appeared.
Ace curled his fingers into a fox sign and snapped his fingers, "Henshin"
[Dual On!]
The giant magnum cylinder hologram appeared behind Ace with the word "Bullet EX" on top. Laser sounds blasted as the cylinder shot out bullets that quickly formed the black under-armor on Ace's body.
[Inferno!]
The Dragon logo shone brightly and let out a roar. Miniature fireballs shot from the logo, converging into jagged red armor plates.
Electronic sounds mixed as the armored parts attached to Ace/KR Geats' body seamlessly.
[BulletDragon!]
A victorious guitar riff rang out as Ace stood ready in his hybrid armor, his rifle materializes in his hands with a satisfying 'click'. Bright optics lit within his masked visor.

Geats flicked his wrist.
"Let's start... the highlight"
The suit lights up.
[Ready?]

[Fight]

(an: Just imagine an epic transition into like a title screen or something)

Geats charged towards the mysterious girl, firing bursts from his rifle. She spun her staff skillfully, conjuring barriers of mystic energy to deflect the bullets. When an opening presented itself, she thrust out a hand and sent jagged shards of lighting streaking towards Geats.
He rolled beneath the attack and came up inside her guard. Grabbing her staff, Geats used her own momentum to fling her across the street. But she spun in midair, landing nimbly on her feet. The girl flourished her staff again and the ground beneath Geats' feet suddenly crumbled away.
As he fell into the fissure, Geats kicked off the walls to launch himself back out. But the girl was ready, conjuring a raging firestorm to engulf the area. From within the inferno, Geats suddenly leapt out with a burst from his gun barrels. He spun gracefully through the air, raining death from above on the mysterious girl in swirling arcs of bullets.
She snarled and summoned a bulwark of magical energy just in time. But the force of Geats' assault sent cracks snaking across its prismatic surface. With a wave of her staff, the bulwark exploded outwards in a dazzling shower.
