In this fantasy world, be a Kamen Rider

"But our weapons."

One of them looked troubled. Their weapons had been reduced to parts. What use were they now? Tsukasa Kadoya paused for a moment, looked down at the scattered gun parts, and looked at Yoru Uta speechlessly. Yoru Uta shrugged, snapped his fingers again, and the parts flew into the air and automatically reassembled, returning to their original form.

The soldiers happily left with their guns; these were lifesavers. Although the guns might not be lethal against the monster, they were at least somewhat effective.

"Senior, how have you been? You're still alive?"

Night Song greeted him, somewhat surprised: "Wasn't your power taken away? I don't believe AR Decade would be so charitable as to let you go."

Tsukasa Kadoya gave a wry smile, spread his hands to show Yoru Uta what he was holding—it was Decade's watch. "He ambushed me, but luckily Zi-O saved me. If I hadn't left this watch for Zi-O before, I wouldn't even have been able to transform."

Has the world of Zi-O entered its apocalyptic phase? Where is he?

Yoru looked around but couldn't find Zi-O. Tsukasa Kadoya beckoned to him: "Come in. This is one of the few remaining resistance bases. The world is almost ruled by monsters now."

"it is good."

Without hesitation or taking any precautions, Yoru followed Tsukasa Kadoya into the building and started the seemingly dilapidated elevator. The elevator descended and slowly reached the underground. When the doors opened, a huge space suddenly appeared before them, filled with many people rushing around, seemingly very busy.

"Senior, he is..."

A young man walked over, greeted Tsukasa Kadoya, and looked at Yoru with curiosity. Tsukasa nodded to him and introduced him, "He is Kamen Rider Build from another world, different from the original world that has been destroyed." He then said to Yoru, "He is the person you are looking for, Kamen Rider Sougo, Tokiwa Sougo."

"Hello."

The two shook hands briefly as a greeting, and Ye Ge cut to the chase, asking, "Zio, what level have you reached?"

After hearing the question, Zi-O lowered his head in shame. Tsukasa Kadoya stood in front of him and said, "I'll handle this. You go ahead and do your work, Sougo."

"Okay, okay."

Zi-O fled as if running away. Tsukasa Kadoya sighed, watched his departing figure, waved to Yoru, and led him to a fairly tidy little room where they sat cross-legged. He then began to slowly recount the story: "Do you know the origin of AR Decade?"

"Uh, isn't it a monster who steals your power?" Yoru was stunned, not understanding what Kadoya Tsukasa meant. The latter shook his head: "Decade's ability can travel through different worlds. I have traveled through many worlds, encountered the original Kamen Rider world and the riders in it, and also encountered Kamen Riders like you in other worlds."

“However, it is very difficult for Riders to grow in other worlds. They are either killed by powerful enemies or fail to achieve anything due to the limitations of the world itself. But it seems that you are an exception.” Tsukasa Kadoya sighed again: “AR Decade stole my power with Another Rider’s watch, but he is not simple. He not only wreaked havoc in the Zi-O world, but also traveled to other Rider worlds and destroyed the Riders one by one. The original Build world, Kamen Rider Build, no longer exists.”

"Tsk, doesn't the Knight's Will matter?"

Night Song frowned. Such a rule-breaking monster would surely have the Knights' Will dispatch powerful knights to subdue him, but there was still no news. Tsukasa Kadoya smiled bitterly: "It's not that the Knights' Will is not doing its job, but the other party is not simple either. Ordinary Another Riders have not reached the point of transcending the world. The identity of that AR Decade is very likely the lower realm manifestation of the monster's will."

"The will of a freak?"

Night Song pondered this somewhat unfamiliar word and suddenly realized that although he was now a true god of the world, he seemed to know nothing about the universe. Compared to the knowledgeable Decade, his knowledge was far too lacking. What Decade was about to say might once again refresh his understanding.

"The Knight's Will belongs to the Order side, so monsters also have their own overall will, which belongs to the Chaos side. Monsters take pleasure in destroying the world, and the current AR Decade may be the embodiment of the monster's will descending. The Knight's Will can only limit its power of descent and cannot do much to interfere with it."

Section 252, page 247. AR Decade

"This is troublesome. It's a powerful figure at the level of the will of the universe."

Ye Ge couldn't help but click his tongue in amazement. The other party was a big shot on the same level as the Knight's Will. Shouldn't a small character like him obediently step aside?

Tsukasa Kadoya shook his head: "The good news is that the power that the opponent descended also has its limits, which is one of the rules. But even if it is limited, it is still far beyond me, especially since he also obtained the power of Decade's travel. Now he is destroying more and more worlds. If this continues, the Kamen Riders will be completely destroyed."

"So, Night Song, come help us."

Tsukasa Kadoya raised his head and looked at Yoru with expectant eyes: "You are the strongest Kamen Rider I have ever seen. You are the last hope."

"What about the king then? If he grows up, he'll probably be even stronger than me, right?"

Tsukasa Kadoya gave a helpless bitter smile: "Sougo does have great potential, but there is no longer any chance for him to grow. Because of the existence of AR Decade, many Riders have been destroyed. I tried to go to other worlds to seek Rider power, but I found nothing. So I gave him the Rider power I had collected, but it is still not enough."

Is that so?

Yege frowned deeply. This news was bad. The so-called strongest Zi-O hadn't grown up, and Decade had turned into this state again. The opponent was still such a formidable existence. This war was really going to be difficult.

"Hmm!" Night Song suddenly looked up, his eyes flashing. His expression changed abruptly, and he stood up abruptly, grabbing Tsukasa Kadoya's collar. Before the latter could react, Night Song had already transformed into Phantom Build, turning both Decade and himself into spirit forms. They passed through the thick ground and flew out of the surface. After regaining their physical form, the two pairs of wings behind them trembled, bursting out with a sudden high speed.

"Cough cough cough, what's going on?"

Tsukasa Kadoya felt dizzy and it took Yoru to put him down. Ignoring the nausea in his stomach, he looked up and asked.

“We’ve been locked on. The other party is no pushover. After all, I just transmigrated here, and I still feel a strong sense of alienation.”

Ye Ge turned around and looked at the gray passage behind him that was beginning to shrink. The moment he was locked on, he chose to leave. In order not to involve the last human settlement, he flew directly back to where he came from. At this moment, the originally stable passage began to shrink, as if it was about to close.

"It seems they don't want me to go back."

Ye Ge chuckled, placed both hands on either side of the passage, and forcefully pulled it outwards. A blood-red light flashed around him, and Pandora's Box appeared and disappeared, forcibly expanding the passage again. However, this was only a temporary solution. Ye Ge turned the driver, and the Genius Bottle emitted a silver light. The light of time stopping enveloped the passage, pausing the gray mirror surface.

"How could I possibly let you have your way? I still have my family over there."

Ye Ge released his hands and used Time Stop to forcibly freeze the mirror at this moment, relying on his abnormal time power to cancel out the opponent's control. However, this did not mean victory. Ye Ge slowly raised his face and looked at the shooting star that suddenly streaked across the sky. The little trick just now was just an appetizer. Now it was time for the main event.

Whoosh!

A meteor fell from the sky, cracking the ground and melting the surrounding concrete. From the crater, a hideous figure slowly emerged, his reddish-purple skin covered in steel-like patterns. The insignia on his chest revealed his identity: a cross, just like the one on the decade, AR Deccade.

"I only sensed the unusual activity in that world, but I didn't have time to go and check it out. I didn't expect you to come here directly."

A deep voice came from Ar Decade's chest. He glanced at Tsukasa Kadoya next to Yoru, a hint of surprise in his voice: "You're still alive? Without your Rider powers, what's the difference between you and an ordinary person?"

“Ar Decade, let’s call you that for now.” Night Song spoke slowly, moving to block the gray mirror. “You instigated Killbus to come to my world, and now you’ve even opened a portal between the two worlds. What is your purpose?”

"Hahaha! What a boring question." Ar Decade laughed mockingly. "Unless Zi-O reaches his peak, no one can defeat me! The Build world no longer exists. Once you are destroyed, the power of Kamen Rider Build will completely disappear, and Zi-O will no longer be able to become the perfect form!"

Ye Ge clicked his tongue in annoyance, realizing he had been underestimated. He shook his head, launched a flying kick, and sent the purplish-black tracks hurtling towards AR Decade, sparking countless fires as they flew across his body. However, he showed no sign of pain, and with a powerful struggle, he tore the tracks apart completely.

"This level of power is impossible to achieve even if one absorbed all of Decade's power." Ye Ge was shocked. AR Decade's strength was beyond imagination. Although he did not have the support of the world, the divine power within him still existed. Even the Dragon God would have to think twice about that kick, but AR Decade simply ignored it.

"It's no use. I will destroy all knights, erase the history of knights, and become the king of all worlds. Anyone who stands in my way will die!"

AR Decade raised his hands, and a huge purple plasma ball hurtled towards Night Song. His palms glowed, and diamonds rapidly grew from them, radiating scorching heat as they struck the incoming plasma ball. The earth trembled, the air tore apart, and Tsukasa Kadoya covered his ears, flying away with the airflow. He would have been instantly vaporized in the center of the battlefield.

"Cough cough cough, a miscalculation."

Night Song withdrew his hand; all the diamonds in his hand had disappeared, and a scorched mark appeared on his armor. He was at a disadvantage in this clash, but he wasn't too disappointed, because the Phantom Build was not just about strength; its infinitely versatile abilities were its core.

Bat wings and eagle wings unfolded simultaneously, and a black steel Gatling gun appeared on Nightsong's body. His figure flashed continuously in the air, and the Gatling gun spewed out torrents of energy, bombarding AR Decade. Each bullet carried a diamond bullet and the high temperature of lava. Even he could not completely block it. He crossed his arms to defend against Nightsong's attacks, and a gray mirror appeared behind AR Decade.

"Come and face all the knights' enemies!"

Section 253, page 248: Build the dial.

A heavy punch was thrown, which, although it did not hit Ye Ge, forced him back. Ye Ge dodged and was about to counterattack when a large sword suddenly flew out from the gray mirror behind AR Decade, spinning towards him. Ye Ge nimbly dodged it, but because of this interference, he lost the opportunity to continue the pursuit.

"cut."

With a displeased click of his tongue, Night Song narrowed his eyes, folded his wings, and hovered in the air, watching the gray mirror behind AR Decad gradually recede. Then, some strange figures emerged from it. It was a group of new monsters, but each of them had a terrifying aura. They were the enemies of every knight, the ultimate monsters.

"These are monsters I found from other worlds. You'll be facing the enemy of all the Riders! If Zi-O doesn't come, then you'll have to take the blame." AR Decade laughed heartily. He didn't think Night Song had any chance of winning. Perhaps due to certain limitations of Another Riders, he was at a disadvantage, but these monsters were the ultimate enemies of the Riders. There was no reason why he couldn't defeat them.

"Evolto and the others aren't here? That puts my mind at ease."

Night Song glanced around and noticed that Evolto was missing. She breathed a sigh of relief. Evolto and Killbus should have been among them, but because of her, she had persuaded them. Now, these two Blood Star people belonged to the Knights' camp. However, for safety reasons, Night Song did not let them come over.

Gamedeus flicked his wrist and retrieved the greatsword he had just thrown. His wings, which looked like those of an angel, unfurled behind him. A group of strange men were eyeing him menacingly. Night Song cleared his throat and beckoned to the group of strange men opposite him: "Come on, I'm sure you're not planning on one-on-one combat."

Boom!

Seemingly receiving a signal, the monsters swarmed forward. Night Song no longer hesitated, activating all 120 of his abilities. The tank tracks crushed AR Decade to the ground, and then the two pairs of wings behind him slammed into Greeed, who was attacking from behind. Coins fell to the ground, and the unicorn drill in his hand kept hitting Gamedeus's shield.

In an instant, Night Song was engaged in battle with a group of strange people, but their strength was not weak either. During the fierce battle, Night Song was hit more and more often. He could probably handle one or two, but with so many of them, and they knew how to coordinate, several cracks appeared on his Build Armor, which were from sneak attacks.

"Cough, as expected, they are all final bosses, not so easy to deal with."

Yege swallowed the metallic taste in his mouth with difficulty. Although only the knight armor was damaged, the opponent's abilities were also endless. The cracked armor showed no signs of healing automatically, and his body was also injured. If this continued, he would definitely be beaten to death by the group. Suddenly, he broke free from the chains of some unknown monster and punched the ground. A blue dragon soared into the sky, briefly obscuring the monster's vision, and flew away with Yege.

"Transform quickly!"

As they flew, Yoru quickly approached Tsukasa Kadoya, who was standing nearby. Yoru urged him urgently, and the latter was taken aback, but he dared not be careless at this crucial moment. Following Yoru's instructions, he took out the watch he had borrowed from Zio.

"DDDDecade!"

"Kamen Ride!"

"Decade!"

As the card was inserted, the belt emitted a mechanical sound, and Decade's transformation was complete. Just as he was wondering what Night Song was going to do, the monsters had somehow gathered together and concentrated all their attacks on one point. AR Decade pushed forward with all his might, and the blinding bullet that almost covered the sun rushed toward Night Song in flight at an incredible speed.

"Eraser! Diamond! Vacuum cleaner! Ghost! Watch!"

Night Song immediately activated his strongest defensive capabilities, even briefly transforming himself into a spirit. The light bullet collided with him and exploded rapidly. Decade watched with trepidation. The impact alone was enough to make his knight armor feel terrifyingly hot, not to mention the energy fluctuations at the center.

After a moment of distortion, space slowly returned to normal, and Night Song's figure emerged from the light. He fell helplessly, freefalling towards Decade. His armor was in imminent danger of breaking, and blood flowed from the cracks, spraying into the air. He did not take any measures to reduce the impact, as if he had no strength left.

"Hahaha! Now, no one can stop me anymore!"

AR Decade pursued, unleashing a purple plasma ball that struck Ye Ge as he landed. Ye Ge was powerless to resist. Once this attack eliminated him, the greatest threat would be removed, and no one would be able to stop him from dominating the entire universe. Even Zio, without the full power of all the Riders, would be unable to pose a threat to him.

The plasma ball illuminated Ye Ge's face, and his previously closed eyes suddenly opened, flashing with blue light. His armor instantly dissipated, and terrifying divine power overflowed from his body. The divine power enveloped the plasma ball, forcefully stopping it. However, the opponent's attack was not simple, and his divine power was constantly being consumed, gradually putting him at a disadvantage. At this point, breaking through the barrier was only a matter of time.

"Be prepared to be attacked, or you might die."

Night Song turned to Decade and said this, then grabbed his shoulder and lifted him up as Decade yelled. He spun him around in the air like a shot put, then his divine power exploded, and a bright blue energy dragon rose from behind him. Night Song threw Decade away with all his might, and the dragon carried him into the sky, rapidly moving away from the battlefield at a speed that broke the sound barrier.

"So that's what he wanted..."

Decade, who had been thrown out, finally understood Night Song's thoughts. He suddenly felt something in his arms, reached into his clothes, and found a red and blue watch in his hand. Decade was slightly stunned, holding the watch face in his hand, unconsciously clenching it tightly. He glanced at the battlefield that was rapidly shrinking in his field of vision, and slowly curled up.

The dragon's energy was almost exhausted. Just as Yege said, he was about to land. However, his hand holding the watch face was still trembling. Yege giving him this watch face meant giving up the power of Build. Without the power of the Rider, could he survive the final monster?

"I hope you survive, Night Song."

Let's leave the watch with the little devil for a while; we'll get it back eventually, hehehe.

Section 254, page 249: Are you angry?

"Huff! Huff! This work of extracting energy is no human being."

Night Song gasped for breath. The weakness emanating from his core made him feel extremely uncomfortable. His Rider Armor dissipated, and he had lost the power to transform into Kamen Rider Build. He had been reduced from a Kamen Rider to an ordinary world god.

"But I have to do it, don't I? It's a way of leaving the world with a glimmer of hope."

At this moment, Ye Ge's divine power finally gave way and collapsed. The plasma ball broke through the barrier of divine power and rushed towards Ye Ge's chest. He crossed his arms and used all his strength to build up a defense. He closed his eyes and prepared to meet the next impact.
