The moon's surface trembled under the force of explosions. Dust clouds glowed orange against the black of space as the Rangers clashed with the Armada's elite monsters. Energy beams streaked across the craters like lightning bolts.
Troy led the charge, his new form blazing crimson and gold, each strike shattering lunar stone. Gia fought with fierce precision beside him, her blade cutting through shadow creatures with golden arcs. Emma soared through the air, firing radiant shots of light, while Orion and Noah unleashed their newfound powers in unison. Jake, armored in his latest form granted by Ohma Zi-O, smashed through enemy ranks with a single punch.
But away from the chaos, a different battle ignited—a storm of destiny between Yuriko and Kamen Rider Fifteen.
Fifteen's armor pulsed with dark crimson energy, each strike heavier than the last. "You think you can protect the legacy of Riders and Rangers both?" he growled, locking blades with Yuriko. "You're nothing but a spark in an endless void!"
Yuriko gritted her teeth, pushing back with all her strength. "Maybe I'm just a spark," she said, "but even a spark can start a new dawn!"
Their clash sent a shockwave that rippled across the moon's surface. As their weapons collided again, Yuriko's belt—the Rider Key Driver—suddenly began to glow. The keychains on her belt vibrated, one by one igniting with the symbols of the Riders whose spirits she had connected with during her training.
"Your will… your courage… your legacy," she whispered, closing her eyes. "Lend me your strength!"
A blinding light erupted, illuminating the battlefield. When it faded, Yuriko stood transformed—her new form blazing red and gold, her armor shaped like a fusion of Rider and Ranger energy. The air around her shimmered with spiritual power.
Fifteen staggered backward. "Impossible…"
"Nothing is impossible when you fight for hope," Yuriko said, her voice calm but resonant.
The final clash began. Blades met with cosmic intensity, Rider energy clashing with
the light of the Gokaiger spirit. Yuriko moved faster than before, each strike carrying the essence of generations of heroes. Fifteen's armor began to crack under the radiant power.
In one final surge, Yuriko leapt into the air, calling out,
"Final Break—Radiant Justice!"
Her energy blade cut through Fifteen's chestplate, sending him crashing into the lunar dust. Smoke rose from his armor as he struggled to stand. "This… isn't over," he hissed, clutching his chest before retreating into a dark portal that spiraled shut behind him.
Yuriko landed, panting but standing tall. The others—Troy, Gia, Emma, Orion, Noah, and Jake—rushed to her side. Behind them, the last of the Armada monsters fell, dissolving into energy.
Troy placed a hand on Yuriko's shoulder. "You did it."
Yuriko smiled faintly behind her helmet. "We all did."
As the dust settled and the moon grew quiet once more, the team looked out toward Earth glowing below them—a symbol of what they were fighting for.
But deep within the shadows of space, the faint laughter of Kamen Rider Fifteen echoed—broken, angry, and dangerous.
The true battle… was far from over.
