Rider Build: Starting in Next Form

After a short time, the alien time train quickly arrived in the era of 2018, but an accident occurred when it came out of the time tunnel. The train track that was extending downwards was laid on the red Time Demon Machine.

Inside the train, Another Den-O sensed something was wrong and rushed curiously toward the driver's cab, trying to salvage the situation, while Another Double Riders kept their eyes fixed on Shingo.

Unfortunately, the Alien Time Train and the Time Demon Machine still collided, and the train began to shake violently, just like a ship hitting a reef. The people in the carriage could hardly stand up. Tide bent over and barely managed to keep his balance so as not to fall.

Shingo, on the other hand, pressed himself tightly against the chair and the wall.

"Alien Double Rider, watch out...!" Before Tide could finish speaking, the Time Train shook even more violently than before, and a series of explosions rang out, blowing open the doors.

Shingo quickly seized the opportunity to jump out of the car and escape.

"Shingo!!!" Seeing Shingo run away, Teid was more anxious than anyone else. He roared at the Otherworldly Twins who were still standing there, "Idiots, hurry up and bring him back to me!"

"Yes!" The two alien riders were startled and their bodies transformed into a wisp of blue wind, disappearing from the train.

With a gloomy face, Tide jumped off the train, turned to look at the Time Train that was exploding continuously, and slowly said, "The history of Heisei Riders, which began with Kamen Rider Kuuga, comes to an end from this moment on."

…………

January 29, 2000, night.

Around a campfire, four people and a demon god sat together. Not far away, two badly damaged time demon god machines lay there, occasionally emitting the sound of sparks.

"Now that everyone's here, what should we do next, Nexus?" The firelight shone red on the four people's faces, and Tsukuyomi asked Luo Yuan.

Luo Yuan silently looked at Feng Talos, who was gathering firewood, and said, "Let that guy explain it to you. He probably knows a lot of information."

“Alright, then I’ll explain.” Feng Talos sighed and threw the firewood he had just picked up next to the campfire. “First of all, that guy named Teed replaced Kuuga himself and eliminated the Riders in this world. Once the original Heisei Rider Kuuga no longer exists, then the history of the Heisei Riders will also cease to exist.”

“That’s why the knights are fictional…” Tokiwa Sougo muttered to himself.

"However, that brat named Shingo seems to be getting in the way of his plans, because that child is a singularity."

"A singularity?" Tokiwa Sougo asked, puzzled.

"Yes, he's someone who won't be affected even if history is rewritten. As long as Shingo exists, history might be able to return to normal. The reason I was able to summon the knights who should have disappeared is because Shingo ran away, while Nexus..."

At this point, Feng Talos paused for a moment, and only continued when he saw that Luo Yuan did not react. "He seems to be from another Heisei Rider world."

"Huh? There are other worlds? Then, is there another me in that world? I'm really curious what he's like." As he spoke, Tokiwa Sougo's face showed a curious expression.

"Well... in terms of academics, you and the other Zhuang Wu are practically two extremes. You're a top student, while he was a slacker who almost didn't graduate." After a moment of silence, Luo Yuan made a fitting comparison.

This statement is tantamount to Luo Yuan acknowledging that Feng Talos came from another parallel Rider world, and that he seemed to be in the era of Zi-O.

"Huh? No way?" Tokiwa Sougo said in disbelief.

“Now is not the time to talk about these things. We need to figure out a way to go back to 2018. The Time Machine was destroyed in such a state that it cannot be repaired in the short term,” Gates said with a headache.

"It seems like the Time Rift won't be an option to bring these two behemoths back, but there are other ways." Luo Yuan took out the Decade Complete watch.

"This is Decade's watch?!" Tokiwa Sougo exclaimed in surprise.

"Okay, let's use it to go back to 2018." With that, Luo Yuan activated the watch.

"decadeplete!" (Knight Decade Complete)

A curtain of aurora appeared before everyone, and then swallowed them along with the two Time Demon Machines.

…………

2018 12 Month 3 Day.

The aurora curtain appeared out of thin air and swept across an open space. The next moment, Luo Yuan and the others, along with two large pieces of junk, emerged from it.

Not far from this open space lies a ruin, where Build Rider Twin Rabbit and Crozier Lava are battling a group of monsters.

"You're back already..." Tokiwa Sougo's expression was still a little dazed. Was time travel really such a simple thing...?

"Are you back? Luo Yuan, Shen Wu has been sealed away by Tid!" Build Rider swung his Fullbottle Destroyer, smashing a monster in front of him, and noticed the group returning in the distance, shouting loudly.

Luo Yuan nodded.

"What do we do next?" Gates asked, his face tense.

"Let's go to the enemy's headquarters." Luo Yuan looked at the black castle with two giant red horns on top in the ruins in the distance.

…………

boom! ! !

With a loud crash, a large gate inside the castle shattered.

"Your door isn't very sturdy. I suggest you replace it with an iron door next time. What do you think?" Luo Yuan said seriously, looking at Tide, whose expression was somewhat distorted in the distance.

Upon hearing this, Tide, whose expression was already somewhat distorted, began to breathe heavily. He quickly composed himself and, suppressing his anger, asked, "How did you get back? Weren't those two Time Demon Machines already destroyed?"

The Time Jackal naturally also had a Time Machine, a tool for traveling through time, inside his body. Therefore, he knew that the two Time Machines should have been severely damaged and could no longer travel through time.

But apart from knowing that he is a Kamen Rider from the Kamen Rider Build era, the only other aspect about this rider is that he is a complete mystery.

"I don't know how you did it, senior. I just passed through something that looked like a wall and came back," Tokiwa Sougo said honestly.

"...Never mind, I've already sealed Shingo away as a singularity. You will soon disappear from this world along with the history of the Heisei Riders." Teedo didn't expect Tokiwa Sougo to be so honest as to tell the whole story. After a moment of stunned silence, he used the power of time to instantly appear in front of the box that sealed Shingo and smiled coldly.

“We’ll defeat them before then!” Geiz said without hesitation, his watch already plugged into the driver in preparation for transformation, as did Tokiwa Sougo beside him.

“Geeiz!” (Gates)

"Zi-O!" (Zi-O)

"Transform!" x2

Just as the two uttered those two words, Teed stretched out his hand, and time around them stopped, freezing Tokiwa Sougo and Geiz, who were about to complete their transformation, in place.

Chapter 422 The Final Stop of the Time Train: Kamen Rider Den-O

"You guys are so noisy and incessant! You shouldn't even exist!" With Tide's roar, a large number of monsters walked out from the door on the side, including Another Den-O and several Another Double Riders. They ignored Tokiwa Sougo and Geiz, who were frozen in time, and stared intently at Luo Yuan.

"Alright, let's count your sins!" the two alien riders said in unison, and then charged towards Luo Yuan in various poses.

“The fluctuation of time… I see. So these Another Riders were captured from different time periods…” Luo Yuan’s eyes swept over the Another Riders present. Without exception, they all had a very peculiar fluctuation. He had sensed this fluctuation before when he used Time Drive to transform. This fluctuation was called Time.

"Then let's finish this quickly." Luo Yuan took out his watch, preparing to transform and fight, but at that moment, everyone present except for Tide and the sealed Shingo disappeared from the room.

"What happened?" Upon seeing this, Tide immediately stood up. What had just happened?

…………

In the station hall of the Time Train.

Luo Yuan held the Knight Watch in his hand. Just a moment ago, they were teleported here, and the monsters were also teleported here at the same time. The two sides were at least four meters apart.

"Where am I?" Feng Talos looked around at his surroundings with a blank expression.

The sudden spatial shift put everyone on alert except for Luo Yuan, who knew the specifics.

Another Den-O was observing his surroundings when a foot suddenly kicked him in the back, sending him sprawling to the ground.

"This is your master!" The newcomer was none other than Kamen Rider Den-O: Holy Sword Form (the form in which he fights possessed by Momotaros).

He assumed his fighting stance, but then he realized that what was in front of him was not his target, but the Another Riders and a bunch of monsters, while his target, Another Den-O, was behind him.

Just as he was about to turn around and continue with his entrance pose, the Another Riders couldn't wait any longer and pounced on Den-O.

Seeing this, Den-O quickly moved back a distance and shouted towards Luo Yuan, "Hey, you kid who got on the train earlier, come help me!"

"This is really..." Luo Yuan silently rubbed his forehead. As expected of the Heisei era's cancer. But he didn't just stand by and watch. Light particles surged from his hands, forcibly controlling the two alien riders and fixing them in place.

Den-O drew four components from his waist—the Electric Cutter—and combined them into his weapon, slicing away an Another Twin Rider blocking his way. He then looked at Another Den-O behind him and assumed a fighting stance once more. "This great one is here!"

"Hey, are you alright? We're both Den-O, how come you're so weak?"

"A sneak attack from behind, how despicable!" This was the first time Another Den-O had ever seen such a shameless person since he transformed into Another Rider.

"Heh, who cares about you! Listen up, I don't need any build-up, I'm going all out from start to finish!" Den-O charged at Another Den-O with his Electric Slicer, casually slicing down the monsters around him that tried to attack him.

"Sougo, let's use both of our Rider Watches together," Luo Yuan said to Tokiwa Sougo beside him.

“Yes, senpai!” Tokiwa Sougo nodded, then took out the Double Rider watch and inserted it into the other side of the driver to perform the transformation that he had not completed earlier.

"Transform!"

"Ridertime!"

"Kamen Rider Zi-O!"

"Armortime!"

"Cyclone!" (Swift wind)

"Joker!"

"w—!" (Double rider)

Two tiny, USB-shaped figures spontaneously assembled onto Zi-O's shoulders, transforming him into Zi-O Double Rider Armor Mode.

"Transformation."

"Nexus Junisred!"

Luo Yuan activated the watch, which was enveloped in a silver light, and then a silver-gray warrior emerged from it.

"w·cyclonejokerxtreme!" (Double Rider·Swift Ace Ultimate)

He took out the watch in his right hand, activated it, and a phantom image appeared. Then, he actively merged with Nexus.

"Phew, I'll take care of you all in one move, Sougo!" Nexus called out to Zi-O beside him.

"Understood!" Zi-O nodded, then pressed two gauges and turned the driver.

Nexus then brushed his arms across the core of his chest, before rotating them parallel to the ground, where terrifying energy gathered.

"Maximum Time Break!"

Zi-O leaped into the air, the two USB-sized figures on his shoulders forming a W shape with Zi-O's feet, and kicked at one of the Another Double Riders.

"xtreme·coreimpulse!"

A blazing orange-gold beam of light shot out from the core of Nexus's chest, carrying the power of Dual Rider Ultimate. For these otherworldly Dual Riders, this beam was deadly.

Meanwhile, the four Another Demon Gods contracted by Den-O—Momo, Urataros, Kin, and Ryu—possessed Den-O once during their battle with Another Den-O, ultimately ending Another Den-O's fight with Urataros's Rider Kick.

A series of explosions echoed through the station.

The flames from the explosion quickly dissipated, and with the Another Den-O Watch destroyed, Ataru Hisanaga returned to his human form.
