The morning sky was streaked with crimson light. The air carried an unsettling hum — a signal Gosei instantly detected from the command base. Three separate energy spikes had erupted across the world at once.
Inside the control chamber, alarms blared.
"Three monsters," Noah muttered, scanning the holographic readings. "All attacking in different sectors."
"Split up!" Troy ordered, his tone sharp and steady. "Gia, Noah — take the beach sector. Emma, Orion — handle the downtown area. Jake, you're with me; we'll cover the city perimeter."
Yuriko, standing near the console, didn't move. Her Rider Keychains pulsed with dim light, whispering voices only she could hear.
"Yuriko," Gosei said firmly, "you must remain here. The Keychains are calling to you — this is your time to complete your training."
Yuriko clenched her fists. "But they're going into battle—"
Gosei interrupted, "And you will fight a different battle. One that takes place beyond this world."
Yuriko hesitated, then nodded. "Alright. I'll trust you."
As the Rangers teleported out, Yuriko walked to the center of the chamber. The air around her thickened with energy. She held out the Kamen Rider Nadeshiko keychain — it glowed brightly, resonating with the others.
"Show me… the path," she whispered.
A blinding flash enveloped her. The base dissolved from sight, and Yuriko felt her body drift into an endless void of light and shadow.

When her vision cleared, Yuriko stood on an endless marble field beneath a swirling aurora sky. Countless emblems floated in the air — each bearing the mark of a Rider: Stronger's thunderbolt, Amazon's claw, V3's triple line, Black's crest.
She took a cautious step forward.
Then a voice spoke behind her.
> "You've come far, Yuriko."
She turned. Standing before her was Kamen Rider Stronger, his armor shining like polished chrome, his eyes alive with lightning energy.
"Stronger…" she breathed. "I thought you vanished."
"I did," he replied calmly. "But here, within the Memory Realm, our spirits linger. You've carried our power… now you must carry our will."
As he spoke, other silhouettes emerged — V3, Riderman, Amazon, and more, forming a semi-circle around her. The air trembled with legacy and purpose.
Yuriko fell to one knee, overwhelmed. "I'm not worthy. I'm still learning—"
> "You are our continuation," V3 interrupted, his voice deep and resonant. "The bridge between worlds — Rider and Ranger. You fight not for one universe, but for both."
Amazon stepped forward, his tone rough but kind. "Your spirit is wild. Strong. But untamed. You must learn to feel the power, not force it."
Stronger raised his hand. A pulse of blue lightning surrounded Yuriko, forming a test circle of energy.
> "Prove your resolve, Yuriko. Show us that the legacy of Riders burns within you."
Yuriko stood, determination igniting her eyes. "I won't let your will fade."
She activated her Driver. "Henshin!"
The armor of Kamen Rider Nadeshiko materialized in a storm of neon-blue light. The Riders watched in silent pride as Yuriko lunged into battle against their phantom constructs — illusions designed to test her mastery.
Each move was fierce, fluid — a mix of Rider technique and Ranger instinct. She blocked V3's rapid strikes, evaded Amazon's feral lunges, and traded lightning blows with Stronger.
Energy exploded across the marble field, illuminating the vast aurora sky.
At last, she landed on her knees, panting but smiling. "I can feel it… all of you. You're part of me now."
Stronger approached her and placed his hand over her heart.
> "And you are part of us."
Light burst from his palm, flowing into Yuriko's chest — merging the Keychains into a single, unified pulse.
> "Rise, Yuriko… the Rider of both worlds."
As the light consumed her, Yuriko's spirit began to ascend — returning to the real world.

Meanwhile, chaos engulfed the Earth.
Near the beach, Noah and Gia fought fiercely against a serpent-like monster that controlled the tides. Every motion it made sent waves crashing onto the shore.
Gia swung her weapon through the foam. "This thing's using the ocean itself against us!"
Noah fired a series of energy blasts, freezing portions of the waves midair. "If we can cut off its energy source—"
Before he could finish, the monster tail-whipped him into the sand. Gia roared and charged forward, slicing through the creature's tendrils. She slammed her morph weapon into its chest, shouting, "For the team!"
The beast screeched as a massive surge of gold energy from Gia's weapon disintegrated it into the sea spray.
Gia exhaled and looked at Noah, who gave a thumbs-up. "Nice work."

Downtown, Emma and Orion faced a hulking insectoid monster whose armor reflected their attacks.
"This thing's reflecting everything!" Emma yelled, dodging another beam.
"Then we'll have to break its rhythm," Orion replied, voice still disoriented by her new form but fierce with focus.
The two moved in perfect sync — Orion flipping over the monster while Emma distracted it from below. Their combined strike created a glowing cross-pattern of energy that sliced through its armor.
The explosion rocked the street. Emma landed beside Orion, grinning. "Still think you're not yourself?"
Orion smirked. "Guess I'm getting used to it."
---
Meanwhile, near the city center, Troy and Jake were struggling.
Two monsters surrounded them — one a lava brute, the other a shadow mimic. Every time they hit one, the other struck from behind.
Jake growled, "We can't keep this up!"
Troy parried a strike, his breathing sharp. "Just hold on!"
Then, through the smoke, a golden ripple of time-energy appeared — and Kamen Rider Ohma Zi-O stepped silently from the distortion.
Troy froze. The Rider's presence radiated power that bent the air around him.
"Ohma Zi-O…" Troy whispered.
The Rider raised his hand slightly — and golden energy surged into Troy's Morpher. His armor glowed, shifting into a brilliant crimson-gold hybrid form, a fusion of Ranger might and temporal Rider energy.
Jake's eyes widened. "Whoa…!"
Troy's voice deepened, echoing with power. "Let's end this!"
He leapt forward, moving faster than before — each swing of his sword releasing waves of light. The two monsters lunged, but Troy unleashed a finishing strike — a blazing spiral slash that tore through both simultaneously.
The shockwave rippled across the city. When the smoke cleared, the monsters were gone.
Troy stood tall, golden energy flickering off him. But when he turned to look again, Ohma Zi-O had vanished — as silently as he had come.

Back in Gosei's chamber, Yuriko's body pulsed with light. Her eyes snapped open — glowing blue.
She exhaled, the Keychains floating around her like stars.
"They've accepted me," she said softly. "The Riders' will… it's now part of me."
Moments later, the others returned, battered but triumphant.
Troy walked in last, his armor still carrying a faint gold shimmer. The others looked at him in awe.
Gia smirked. "Let me guess — Ohma Zi-O?"
Troy nodded. "Yeah. He didn't say a word… but I think he's guiding us."
Yuriko looked at him knowingly. "He's preparing us — for something far bigger."
The chamber fell silent. Outside, the storm clouds rolled over the horizon — and in the depths of space, the Armada stirred once more.
