In the endless darkness of space, a single flash broke through the void, casting its light down.
The artificial sun had long gone dark. But now, radiance once more blanketed the planet.
That gleaming brilliance—like a true sun—scattered every shadow, illuminating everything below.
The white flames burning on the bodies of the Glamoth Iron Cavalry reflected in that glow. Within it, they felt each other's hearts.
They believed in him, and he in turn acknowledged them.
When they placed that symbol of friendship upon his hand—
When Hoshigaki Sora saw how they had crossed the starry sea to return—he knew. Words were no longer needed between them.
Thus the wish echoing in his heart, borne on the feelings of all, condensed here.
Black and white interwove seamlessly, as though they had always been meant to.
Upon the buckle's hilt was set a stroke of crimson—the booster, melted together in the fire of their bond.
This was the proof born at the peak of friendship.
[Firefly Sword]
And as for how to wield it, there was no need for words.
Sora split the two buckles, slotting them into his Driver at his waist.
'[SET! WISH!]'
"[Henshin]!"
The long blade upon the buckle split open, fierce flames engulfing him, swallowing his body whole.
Then—swordlight cut the fire apart, birthing upper and lower armor from its blaze.
Titanironia saw this, and her emotions burst free.
[You…!!]
Why? Why?
Why did he get to represent companions?
Power swelled in her body, and in defiance of all physics, countless insectile spikes erupted around Sora, each aimed at a vital point.
But he did not even glance at them.
'[SHINING GENERAL!]'
'[FIREFLY SWORD]!'
Two pairs of hands lowered the armor onto him.
Gentle. Almost careful, as if friends were helping him fasten it.
The spikes launched in volleys, like a swarm determined to kill.
Smoke swallowed him whole.
Titanironia narrowed her eyes. Had it worked?
The brilliance around them dimmed, as though his light was fading.
[It was a success…?!]
Just an illusion, after all. What right had one man, with hollow bonds, to stand beside me?
His armor is weaker than before.
[Only I can redefine the cosmos.]
Yes. That was correct.
When I ascend as an AEON, loneliness and silence will vanish from the universe forever!
So she believed.
She turned to the Iron Cavalry, locked in battle against the replicas.
She wanted to see how they faltered when their fragile bond was shattered.
But they did not falter.
They fought on, unbroken.
Limbs rained down. Their flames did not waver.
[See? As expected. In the end, no one cares. In the end, all that remains is—]
'[READY, FIGHT!]'
She froze. Her gaze snapped back.
WHOOSH!
The smoke split in a single stroke of white steel.
And from it stepped Sora. Who else could it be?
[You…!]
"I told you. Not until I fall will you escape."
He straightened, sword reborn, pointing straight at her.
"This is our bond—yours and mine. A bond of no retreat."
If she sought to drag everything back into the "truth" she clung to, then he would sever those chains today.
That was their bond.
Titanironia fell silent.
Before her no longer stood a man clad in green.
White and black wove together over his body, simple yet striking armor.
Two colors, balanced as if they had always belonged.
The blade in his hand was reforged—the booster as hilt, the edge woven from the fire of his bond with them.
This weapon would not break like those before.
So long as their hearts held firm, this blade would remain sharp, unyielding.
Behind him still fluttered a black cloak.
But now, upon it, a golden emblem shone like a firefly.
This was no mere upgrade.
This was his form alone—
Kamen Rider Tycoon—Firefly Sword.
A form born not of vengeance, but of the wish to bring happiness, to walk with companions into a beautiful future.
To protect that wish—the Shining General had come.
His body had no gleaming ornaments, no golden flare.
And yet, on this world swallowed by night, he was the brightest of all.
"Come. This will be our last."
WHOOM!
Sora charged. Fire lit his blade.
Titanironia's gaze chilled to ice. She did not dodge. She would meet him head-on.
The burning sword crashed against her remaining arm.
Flame spread—her godflesh burned.
She had been wounded.
But she did not care. She struck back, wild, relentless.
Her blows shook the world, each strike spilling her entire being into destruction.
Her tactics were gone. She fought for only one thing: kill this man.
And yet, under her storm, Sora endured.
He moved with sharp precision, slipping through gaps, blade flashing.
Every strike left burning trails across her body.
With each swing, white flames grew hotter, searing deeper.
Her divine body could not ignore it forever.
It hurt.
But if killing him silenced this lie, then pain was nothing.
Her eyes fixed only on him.
Her strikes grew reckless.
But the more she flailed, the more she bared herself.
Sora drew breath. Flame roared brighter around the [Firefly Sword].
He pulled the throttle—fire burst from the [Driver], surging into the blade.
'[FIREFLY SWORD STRIKE!]'
He carved a blazing sun in the air.
It blazed like it was truly there, shining around him.
Titanironia hurled herself forward.
But her inexperience showed.
SHING!
The blade flashed like a falling star.
It struck her opening, cut through.
Light pierced her godflesh and seared into the distance.
Her massive body trembled. In her eyes—an emotion hard to name.
[I will never admit it. I will never believe again…]
Betrayal had buried countless companions. She would never trust another.
Only herself.
Her sole hand trembled, straining to heal the wound that could split her in two.
Sora stood, watching.
She turned, gaze pure, resolve unshaken.
And he understood.
So it was.
No more needed to be said. Her path had already fixed this end.
"Someone's grandmother once said: if you cling too much to yourself, one day you'll fall into darkness."
Sora's voice was steady. "I am their friend. They are mine. We can lift each other."
"But you… who will pull you out of the dark?"
He pulled the throttle. Fire erupted once more.
'[FIREFLY SWORD VICTORY!]'
"This… is the end!"
