The Man in Black

"Why did you have to wake up now?"

Seeing Gu Yu staring at him warily, the man in black knew that victory without a fight was no longer possible. He drew a card from his card case.

At the same time, Gu Yu clearly saw that the man's sword-holding left hand bore a Knight Emblem identical to his own.

"The Power of Decade..."

"Exactly."

As a magenta glow shone from Gu Yu's right hand, the man in black displayed the emblem on his left hand before Gu Yu. It then burst forth with a pitch-black radiance.

In an instant, Decade Drivers appeared around both their waists.

However, unlike the magenta Driver at Gu Yu's waist, the Decade Driver around the man's waist was primarily black.

"Henshin!" * 2

[Kamen Ride Decade]

[KamenRide Dark Decade]

After throwing their respective transformation cards into their Drivers, the magenta Decade and the pitch-black Decade descended into this space at the same time.

"At this distance..."

After transforming, Dark Decade assessed the distance between them and drew a card from his card case.

[Kamen Ride Leangle]

"Leangle? I think I get it."

[Kamen Ride Chalice]

After switching forms, both of them drew the cards they intended to use.

Staring at the magenta Decade he intended to kill, Dark Decade sneered and threw two cards into his Driver.

[Attack Ride Stab]

[Attack Ride Blizzard]

After loading the cards, Dark Decade slammed both palms heavily against the ground.

[Attack Ride Stab] and [Attack Ride Blizzard] were both Undead Seal Cards possessed by Kamen Rider Leangle.

Stab was a card obtained by sealing ♣2 Bee Undead, and its effect was to enhance the power of piercing attacks.

Blizzard, meanwhile, was a card obtained by sealing ♣6 Polar Bear Undead, and its effect was to enhance ice-element attacks.

If used separately, these two cards might not have posed much of a threat.

But when Dark Decade combined them, countless sharp ice spikes instantly erupted from the ground.

[Attack Ride Float]

Unfortunately, before Dark Decade could complete his attack, Gu Yu had already anticipated the enemy's general movements.

He had not chosen Kamen Rider Chalice just for the joke. In fact, among Riders in their base forms, this Rider's abilities were exceptionally strong.

The ground was sealed off by endless ice, while those ice spikes erupted with terrifying destructive power.

However, the [Attack Ride Float] Gu Yu had chosen was a card that sealed the power of ❤4 Dragonfly Undead.

Its effect was to grant its holder the ability to levitate.

The ground had indeed been sealed off at that moment, but Gu Yu, who had already floated into the air, was completely unaffected.

On the contrary, he had already launched another wave of attacks from above.

[Attack Ride Tornado]

Catching the weapon that appeared from thin air—the Awakening Bow—Gu Yu swiped the card and aimed the bow directly at his enemy.

As its name suggested, [Attack Ride Tornado] granted the holder a tornado attribute bonus to their attacks.

After obtaining the power of ❤6 Eagle Undead, the light projectile fired from Gu Yu's Awakening Bow shot toward Dark Decade on the ground like a gale.

"Hmph, a cheap trick."

[Attack Ride Smog]

Dark Decade, standing on the ground, directly activated ♣9 Squid Undead's power. Using [Attack Ride Smog] to summon a cloud of smoke, he obscured Gu Yu's vision.

"He vanished? No, that's not it."

Unable to observe the enemy's movements on the ground, Gu Yu immediately swiped another card.

[Attack Ride Reflect]

At the same time, a similar sound effect suddenly rang out from the ground.

[Final Attack Ride LLLL Leangle]

Within the smoke, Dark Decade transformed into Leangle. Stepping on the ice spikes, he leaped high into the air and launched a fierce assault straight at Gu Yu's chest armor.

With both the ice and the force of the kick amplified, Gu Yu immediately felt an intense pain erupt in his chest.

Yet at the same time, after landing his blow, Dark Decade did not press his advantage. Instead, as though he had also suffered some kind of injury, he let out a muffled groan and fell toward the ground.

[Attack Ride Reflect] was the final card Gu Yu had chosen.

He did not know which direction the enemy would attack from, and trying to adapt to every possibility was far too risky.

Even though less than a minute had passed since the battle began, Gu Yu had not forgotten one crucial fact.

His opponent also possessed the Power of Decade. Against such a strange and unpredictable enemy, relying on luck was simply a path to death.

That was why he had chosen the Seal Card of ❤8 Moth Undead.

And this card's effect was to reflect the enemy's damage.

Dark Decade's finishing move was quite powerful, and the damage Gu Yu suffered truly did not feel good.

However, under the reflection of Moth Undead's power, Dark Decade suffered the exact same damage from that strike.

Whether it was Kamen Rider Leangle or Kamen Rider Chalice, both Riders had the same defense of 120T.

After that attack, the damage they had suffered was completely identical.

Mutual destruction.

But how could Gu Yu, who had been prepared from the start, lose focus over such pain?

Before his enemy fell, he had already grasped the card he had prepared.

And now, the opportunity had come.

[Attack Ride Bio]

[Attack Ride Bio] was a card that sealed the power of ❤7 Vine Undead.

And this card's ability was to control vines and attack the enemy.

Before Dark Decade could land on the ground, countless Undead vines suddenly sprouted from the earth and surged toward him.

But at that moment, before Dark Decade could be bound by the vines, he threw out a card.

"Good timing. What a shame."

[Form Ride Agito Flame Form]

After switching into Flame Form, Dark Decade's body was indeed bound by the vines.

But less than a second later, Dark Decade released seven-thousand-degree flames from his right wrist and instantly burned away every vine around him.

"A fine battle. Even I felt my blood boil."

After burning away the surrounding vines, Dark Decade looked at the space, which had suddenly become unstable, and sighed.

"But unfortunately, there isn't enough time."

After saying that, Dark Decade directly canceled his transformation in front of Gu Yu.

"Next time, let's find another chance to fight. Your body..."

"—Will become mine sooner or later!"

After the man canceled his transformation, Gu Yu saw a face that was incomparably familiar to him.

No, that was not quite right...

The man's appearance was completely identical to Gu Yu's current appearance!

The next moment, Gu Yu's consciousness sank into darkness.

And this space shattered completely.
