Firefly is stunned by her own strength. Without the pain of Entropic Decay and even barehanded, she easily defeats a squad of low-level Jyamato. But the noise draws in more—several times the number.
She realizes that while she could fight them all, it would be inefficient. It's time to transform.
Each Jyamato kill earns her 0.5 points—not much, but the quantity makes it worthwhile.
As the monsters approach, Firefly raises her fist to her chest and extends her other hand, holding a glowing, winged object resembling a giant firefly. Behind her, the mech SAM begins to materialize.
"Are you ready?"
"Already ready."
"Ignite the heart—SAM Mech!"
"Burn the fire, crush the foe!"
She imagines a dramatic transformation sequence, quoting Elio and invoking phrases like:
"Leave now, and no one gets hurt. Otherwise…"
"I will ignite the sea!"
Of course, that was just her imagination. But who could resist the joy of transforming?
"Transform!"
With dazzling effects, Firefly fuses with SAM and becomes the Stellaron Hunter—SAM.
Chapter 6 Continued: Mech Warrior Unleashed
Now clad in sleek silver-and-gold armor, Firefly is no longer a delicate girl—she's a powerful mech warrior.
The Jyamato hesitate, then charge. SAM responds with a thunderous punch, vaporizing them instantly.
She tears through the horde like a lion among sheep. Her points soar, and the thrill of battle overwhelms her.
"Combat—bliss!"
"Hack-and-slash—ecstasy!"
These monsters are bred for destruction, created by Archimedel in the Jyamato Garden using fallen DGP contestants as fertilizer and broken Rider cores for genetic upgrades.
They learn and evolve, even mimicking human speech and appearance. But to the audience, it's all just entertainment.
SAM initiates Action One: BHF–Skyfire. Flames burst from her legs as she leaps into the air and delivers a flaming kick like a meteor, obliterating a massive cluster of Jyamato.
"So strong… so satisfying!"
She's drunk on power. Once a shut-in otaku, now a mech warrior beyond her wildest dreams.
But this is just the beginning.
She wonders what it would be like to fight other Kamen Riders—especially in the Geats world, where betrayal and infighting are common.
Suddenly, a massive Jyamato Fortress appears. SAM's display scans it, but data is limited. Firefly recognizes it as the Slug Fortress, a high-level enemy.
Jyamato ranks are modeled after chess pieces: King, Queen, Rook, Bishop, Knight, Pawn. Above them are Jyamato Gods and Apostles.
Some rare types, like the Slug Fortress or ancient beasts, defy classification. "Last Boss" Jyamato can destroy entire worlds and wipe out Rider teams.
This fortress spawns endless Jyamato. Destroying it would yield massive points.
"If I kill it, I'll earn a ton of points."
She doesn't care if she steals Geats' final boss. She's done sympathizing with Ace Ukiyo—her priority is power.
She flies toward the fortress, but a tentacle lashes out like a spear. SAM counters with a flaming punch, shattering it.
Chapter 7: The Chosen One—SAM
Below the fortress, Keiwa Sakurai and Kurama Neon are trapped.
The road ahead has collapsed, walls block the sides, and Jyamato swarm from behind. Above them, the fortress's tentacles destroy buildings, one of which is about to fall on them.
"What is happening? Is this the end of the world?"
Keiwa is panicked. He'd barely escaped the ramen shop thanks to a bear-headed Rider who died shortly after.
Then he ran into Neon, whom he recognized from his sister's livestream obsession. They fled together, but now they're cornered.
Neon is devastated:
"Are we going to die? I haven't even succeeded in running away from home yet…"
The sound of the collapsing building grows louder. Neon crouches, covering her head in fear.
