Atomic Collapse

After Bronya let out that cry, a giant, pitch-black robot suddenly materialized from the void.

Project Bunny. Though its name sounded somewhat cute, Gu Yu, facing this enemy head-on, didn't think this thing resembled a "bunny" at all.

Its pitch-black armor gleamed with an incredibly dazzling luster.

Steam continuously vented from the metal on Project Bunny's head.

The weaponry on its arms exuded an aura of primal violence.

In short, this thing looked like trouble.

The moment Project Bunny appeared, Gu Yu immediately pulled the trigger, unleashing a barrage of enhanced projectiles like a storm.

However, Project Bunny merely raised its heavy right arm, shielding itself with the Rider Shield on its arm, and blocked all of Gu Yu's bullets.

Simultaneously, after stopping the barrage, Project Bunny's head erupted with an ominous red light before it charged directly at Gu Yu.

[AttackRideInvisible]

In the past, Gu Yu used to think that such large mechs would inevitably lack mobility due to their slow speed when fighting humanoid targets, making it difficult to hit them.

But only through actual combat did Gu Yu realize how utterly wrong that conclusion was.

The manga, games, and anime he'd encountered all depicted large weapons as incapable of precise movements.

However, in real combat, Gu Yu discovered that these large technological weapons possessed superior targeting and acceleration systems.

Both in attack speed and accuracy, these large weapons far surpassed ordinary soldiers.

If Gu Yu hadn't kept the [Attack Ride Invisible] card in his hand as a precaution, he might have been sent flying by Project Bunny's Rider Gun right then and there.

"Huh? Strange, where did it go?"

Seeing Project Bunny's Rider Gun shatter the figure Gu Yu had transformed into, Bronya vigilantly scanned her surroundings.

"Project Bunny... were you unable to scan that thermal signature just now?"

"It actually escaped? How strange, aren't they supposed to be in a protective relationship with Raiden Mei?"

After using Project Bunny to perform a thermal scan of the area, Bronya frowned slightly.

Based on Gu Yu's actions just now, Bronya hadn't sensed any intention from him to directly confront Project Bunny.

And according to Project Bunny's scan results, he was no longer in the vicinity.

But for some reason...

Bronya's heightened senses, honed by her assassin training, kept warning her not to let her guard down.

"Never mind, since he's disappeared, Bronya doesn't need to waste any more time."

Saying this with feigned casualness, Bronya walked towards the room where Raiden Mei and Kiana were resting.

"Bronya's mission is to take Raiden Mei back anyway. As long as the mission is completed, nothing else matters."

As she said this, Bronya's demeanor instantly became alert, like a startled cat.

Just moments ago, she had clearly felt a gaze lock onto her.

[KamenRideKabuto]

"Little girl, I must say, your taunt was quite effective."

"Project Bunny!"

Sensing the source of the gaze, Bronya immediately leaped backward, landing behind Project Bunny.

Gu Yu's figure, which had just reappeared, transformed into a wine-red rhinoceros beetle knight.

At its master's command, Project Bunny activated its acceleration system, erupting in a burst of blue acceleration flames before charging towards Gu Yu.

[AttackRideClockUp]

"But this time, I'm actually a little angry!"

"Clock Up, activate!"

At that moment, Gu Yu, who had activated the Clock Up ability, entered a world of high speed.

Transformed into Kamen Rider Kabuto, Gu Yu's speed increased a thousandfold after using Clock Up.

At this moment, Project Bunny, bursting with extreme speed, appeared slower than a snail in his eyes.

"Ah, let me conduct a little experiment."

Grasping the Kabuto-exclusive weapon, the [Kunai Gun], that had just appeared, Gu Yu leisurely approached Project Bunny while taking out a card from his deck.

"Although this mecha is currently materialized, it's essentially a construct made of energy and Honkai Energy."

[FinalAttackRideKKKKabuto]

"If its atoms were to collapse, could this energy construct maintain its form?"

After swiping the finisher card, the armor on Gu Yu's body condensed azure currents, which converged onto the Kunai Gun in his hand.

Then, switching the Kunai Gun to its kunai mode, Gu Yu aimed the short blade at Project Bunny's right arm and slashed down.

"Now, let's begin the experiment."

"Avalanche... Slash!"

After delivering a slash, a crack immediately appeared on Project Bunny's right arm.

However, this crack, which should not have affected the main body, began to spread wildly in the next moment.

Although Kamen Rider Kabuto gained the Clock Up ability to increase speed after switching to Rider Form, its punching and kicking power, as well as its defensive capabilities, significantly declined.

To enhance the destructive power of this form, Zect, while developing this Rider, gave its ultimate move a special effect.

The name of this special effect is Atomic Collapse, and its effect is exactly as the name suggests: it directly collapses enemies that take damage at the atomic level.

Project Bunny's armor, which should have been incredibly tough, was struck by Gu Yu's slash. Due to the Atomic Collapse effect, it suffered a negative buff that prevented it from maintaining its main body.

The next second—Project Bunny's entire arm, unable to be maintained due to the Atomic Collapse effect, dissipated into the air on the spot.

"Very good, the experiment is a success."

After completing this experiment, Gu Yu casually tossed the Kunai Gun in his hand aside and coldly walked towards Project Bunny.

[Final Attack Ride Kabuto]

"I don't want to keep going head-to-head with you, big guy. So, make your exit here."

Upon reaching Project Bunny, Gu Yu could feel that the time he could maintain the Clock Up ability was running out.

"Rider..."

"Kick!"

Staring at the mecha before him, Gu Yu spun on his own axis and kicked Project Bunny's body.

The next moment, as electricity and the Atomic Collapse effect flowed into Project Bunny, the Clock Up ability was immediately released from Gu Yu.

Bronya, who still didn't know what had happened...

--watched as her companion, with whom she had been fighting, simply vanished before her eyes.
