[Rabbit!]
With a flick of the switch on the Broken Ice bottle, Sento folded it in half and inserted it into the Build Driver.
[RabbitAndRabbit!]
"Build up!"
[Are you ready?]
[OverFlow!]
The energy exploded around him.
Scarlet light surged as a crimson rabbit hologram appeared behind War Rabbit. Segments of armor split apart midair and aligned into place.
With fluid momentum, Sento leapt—bouncing, flipping, and weaving through the air—snapping the armor pieces onto his body in a rapid sequence of acrobatic movements.
[Pure Red's Swift Jumper!]
[Rabbit-Rabbit!]
[Yabee!]
[Haee!]
Kamen Rider Build: Rabbit-Rabbit Form!
As over-the-top as ever, the DJ-like sound effects blared through the air like a rave on caffeine. And yet—even with all that flash—Sento's transformation lacked the style it could have had.
"Seriously, Katsuragi… was this really the best you could do?" Ryuga muttered, watching from the sidelines.
If Katsuragi Takumi—the true genius behind the system—had transformed, the armor would've attached automatically. Sento's flashy jumps were just patchwork.
Still, this new form wasn't all for show.
In the VIP box above, Prime Minister Mido Masakuni stood up in shock.
"That—That's Twee-Dong-Dong!"
"...What the hell did I just say?" he blinked, confused by his own outburst.
Domination
Before Gentoku—now Kamen Rider Rogue—could react, War Rabbit's red blur zipped across the battlefield and struck him square in the chest. The impact sent him sliding backward, struggling to stay upright.
"This power…" Rogue gasped, "It's just like the uncontrolled Hazard form—but how are you still conscious?!"
"I've mastered it," Sento said, voice steady. "This time, I won't lose control."
With lightning-fast speed, Sento vanished and reappeared around Rogue, landing precise, punishing strikes from every direction. Rogue could barely defend, overwhelmed by the relentless assault.
"This is justice—the power of Kiryu Sento!"
Sento summoned his signature weapon—the Full Bottle Destroyer—which transformed from sword to cannon in a click.
[Rabbit!]
[FullBottleBreak!]
He loaded a bottle, fired a powerful energy blast—and followed up without pause.
[Rabbit! Panda!]
[JustMatchDesu!]
[JustMatchBreak!]
[Rabbit! Panda! Taka!]
[MiracleMatchDesu!]
[MiracleMatchBreak!]
Three devastating blasts rocked Rogue's armor. He was stunned, unable to respond before Sento activated his final move.
[Ready? Go!]
[HazardFinish!]
[Rabbit-Rabbit Finish!]
War Rabbit soared high, launched from his own momentum, and came down like a guided missile. With his right leg extended, he compressed all his energy into a pinpoint kick—driving it square into Rogue's helmet.
The sheer force blasted Rogue through the arena wall and out into the next room.
Seito's Desperation
From the viewing platform, Misora blinked. "Wait—does that count as a win?"
The Seito referee quickly interjected, "Victory is determined only by surrender, transformation cancellation, or inability to continue fighting. Even if combat leaves the arena, the match must proceed."
Sento had anticipated that, and without hesitation, leapt out after Gentoku.
Namba's Countermove
In the Seito command room, Namba Jusaburo remained calm.
"No need to worry," he said, waving off Prime Minister Mido's panic.
Utsumi, now a cyborg-like operator, confirmed, "The Double Rabbit form data has been successfully uploaded. Counter-strategies have been integrated into Rogue's drive."
"Excellent," Namba nodded, smirking.
Sure enough, Rogue stood back up. His armor's internal HUD now displayed tactical readouts, projecting War Rabbit's attack patterns.
"Time to turn the tables," he growled.
Now, no matter how Sento attacked—jabs, slashes, cannon blasts—Rogue countered everything perfectly. It was as if he could see the future.
Buying Time
Sento wasn't surprised. He even smiled as Rogue's blows landed.
"That's it… waste your time."
Though he was clearly on the defensive, he showed no urgency. Each hit he took was calculated. His new armor gave him enough durability to hold out—and his goal wasn't victory.
It was delay.
He needed to stall—until Ryuga returned.
As Gentoku monologued about strength and sacrifice, Sento internally rolled his eyes.
"All of this strength… the system you're using… I built it, idiot."
"I gave up my pride, my name—everything—to save this country!"
"You also gave up your common sense."
Still, Sento let the battle drag on. The sun began to rise.
Reinforcements Arrive
"Yo! Sento! Why are you still getting beat up?!"
Ryuga's voice finally rang out.
"Took you long enough!" Sento called back, dodging another blow.
"Nabeshima family's safe. Already on a ship heading overseas."
Sento staggered. "You mean I've been taking punches for six hours for nothing?!"
"Oops. Forgot to tell you."
"I hate you."
"...What are you two talking about?!" Rogue demanded, confused.
Sento's expression darkened.
"This is all your fault!"
[MaxHazardOn!]
He swapped bottles mid-combat.
[Tank!]
[TankAndTank!]
"Build up!"
[Are you ready?]
[OverFlow!]
[The Deep Blue Warrior of Steel!]
[Tank-Tank!]
[Yabee!]
[Tsuee!]
The same transformation sequence played again—except this time, red rabbits were replaced by miniature blue tanks that slammed into place around his frame.
Where Rabbit-Rabbit was speed and finesse, Tank-Tank was pure destructive power—a walking fortress of war.
"Now it's my turn."
