I am Kamen Rider who reverses dimensions

Thus, all the Kamen Riders of Helheim Forest were divided into three groups. One group was guided by Tsukasa Kadoya to the front lines to prepare for battle through the Aurora Veil. Another group was sent from the timeline by Yuto Sakurai using the Zero Train. After confirming that Bataan had not used the power of Kamen Rider 'den-o' to leave any contingency plans in the Desert of Time, they joined the battle. Finally, Ryotaro Nogami and others piloted the Electric Train, carrying Gengo's body, along the gap between reality and the Land of the Dead to meet Gengo. Now, in this life-or-death crisis, the Electric Train went all out, without holding back, and forcefully blasted a safe airspace out of Bataan's fortifications. It was during this moment that the Electric Train took away Gengo and Shokichi Narumi.

"Oh no!"

The moment Gengo entered the electric train, his soul returned to his body. At the same time, the pain suffered by those souls was instantly and accurately transmitted to his body. Gengo immediately couldn't help but spit out a mouthful of blood, but right away, Gengo grasped 'Luna', released the 'hollow' of the heart's nascent form, and let it beat again to prevent himself from truly dying again. However, as his heart beat, blood seeped out from the cracks, wetting his clothes. Gengo expressionlessly grasped 'Luna', creating an illusion to cover it up and avoid being questioned.

"Yuanxiang, are you alright?"

Ryotaro Nogami walked over nervously, wiping the blood from Gengo's mouth with a handkerchief, and asked with concern:

"If you feel unwell anywhere, be sure to say so. There are medical devices on the electric train."

It's true. After the Battle of Sky Rift, the terminal station renovated all the Time Trains, including adding medical facilities. Although this might be exploited by villains, it's unacceptable for train passengers to die because they receive better treatment.

"I'm fine. Oh, right, Ryotaro, this is for you."

Gengo shook his head, refusing the medical treatment, and then handed the Lockseed of Kamen Rider 'Den-O' to Nogami Ryotaro, saying:

"This is what I brought back from Bataan. I think it was produced there when you were defeated. See if you can sense or discover anything. Don't let this thing hurt you."

'........'

Nogami Ryotaro silently accepted the Lockseed, its surface still stained with blood. In fact... he knew there was a 'den-o' Lockseed in Bataan; it was part of the plan. This Lockseed wouldn't imprison itself; on the contrary, when necessary, it would respond to the Lockseed's call, joining the battlefield from the Forest of Helheim and catching the enemy off guard.

But now, even the most mischievous Momotaros couldn't bring himself to tell Genji the truth about the Lockseed. Judging from Genji's expression, they had no doubt that he had risked his life to retrieve it. This...this made them...

"Did I... mess something up?"

At that moment, Gengo, leaning against the car window, saw what was happening below. All the Kamen Riders who had been defeated had reappeared, and both Showa and Heisei Riders were fighting side by side, completely unlike their previous conflict that had led to a fight to the death. If Gengo still didn't realize what was going on after seeing this, he would have wasted all his time as a detective.

"Yuanxiang, actually it wasn't chaotic there."

Ryotaro Nogami offered a somewhat flustered explanation, but before he could finish, Genji waved his hand, sighed, and said softly:

"Let's not worry about that for now. We'll deal with right and wrong after the fight. Let's go, Ryotaro, it's time to fight. We have to wipe out the Bataan! These guys might be remnants of Shocker!"

"Wait! Wait!!"

Seeing Genjiro stand up, striding confidently towards the battlefield, Nogami Ryotaro's voice rose, devoid of any weakness. He pressed the boy's shoulder, forcing him into a chair, and looking into his eyes, said with utmost seriousness:

"No, you can't fight anymore! We've already heard about your physical condition from Yuto, so please leave it to us!"

Ryotaro Nogami stared intently at Genji and said, enunciating each word clearly:

"Leave the rest of the battle to us! It's settled then, Momotaros, let's go!"

"Oh!"

The red-clad demon god roared with great enthusiasm, stopped beside Yuanxiang, took a deep look at the boy, reached out and tidied the boy's somewhat messy hair, and then rushed off the electric train.

"Haha, this feeling of being taken care of is really wonderful."

Yuanxiang chuckled twice, then leaned back in his seat. A soft sound escaped from his throat. Although there were no wounds on his back, the burning sensation from resisting the explosion of the energy pod had intensified with the time it took to return to his body. It was likely that his back was in this state before the injury imprinted on his soul healed on its own.

"Hello, please use it."

Just then, a girl walked over and handed Gengo a strange cup of coffee. She was Naomi, a passenger attendant working in the dining car of the "Electric Train." Her main responsibilities were cooking and serving in the dining car, as well as making announcements, confirming ticket sales, and checking goods. Gengo had seen her before during the Battle of the Sky Rift, but at that time she was busy making coffee while counting the number of people on the train, and they hadn't spoken.

Where is your train commander?

Yuanxiang remembered the old man who looked exactly like the stationmaster at the terminal station, but after looking around and not seeing him, he asked curiously.

"The train conductor is away on a business trip. Me... um? Are you awake? I'll go make some coffee."

Before she could finish speaking, Naomi saw Narumi Shokichi wake up beside her and hurriedly got up and ran to the platform. Gengo glanced at the coffee topped with colorful whipped cream, took a sip with a subtle expression, and then his expression became even more subtle. How should I put it, he couldn't quite handle the taste.

"here it is....."

"The real world outside Bataan."

Gengo put down his cup and answered Narumi Sokichi's question. Then, he pointed to the window, indicating that Narumi Sokichi should look outside. The former detective looked out curiously and saw the half-green, half-black Kamen Rider W punching and kicking a group of Bataan soldiers who were surrounding him.

"Are those... Shotaro and Philip?"

Narumi Shoji said in a low voice in surprise, looking at the Kamen Rider's skillful movements, he seemed to vaguely see the figures of the two children he knew behind him.

“Mr. Narumi, look at that red Kamen Rider, yes, yes, the one that can transform into a motorcycle.”

At that moment, Gengo pointed in a direction to Narumi Shokichi, pointing to Kamen Rider Accel and whispering:

What do you think of that Kamen Rider?

"Hmm... His movements were swift and efficient, and although there were still some flaws, it was still pretty good. Gensou, why did you ask me to pay attention to him?"

Narumi Shokichi asked curiously, not believing that Gensou just wanted him to give his opinion.

"His name is Terujiro."

Yuanxiang said with a smile:

"He's Akiko Narumi's fiancé, the kind who's already engaged."

"Roar↘Roar↗"

Upon hearing this, Narumi Shokichi's eyes flickered slightly, and his gaze towards Terui Ryu became serious:

"My son-in-law, let me see what kind of young man has captured the heart of my lovely daughter. Yuanxiang, please excuse me."

After saying that, Narumi Shokichi took the hat that Gensou handed him, put it on, and left the train. At the same time, Terui Ryu, who was fighting monsters, suddenly shivered. He subconsciously rubbed his arms and looked around. For some reason, he suddenly felt like he was being watched by some incredible guy.

Genji smiled slightly. Well, it wasn't quite appropriate, but he suddenly had a mischievous thought. He felt that if it succeeded, it would be very interesting. No, no, no, he wasn't doing this for the sake of fun. He was doing it to make the reunion between his seniors and Mr. Narumi more natural.

“Mr. Gengo, your wickedness is practically overflowing from your face.”

Naomi, who was carrying coffee, squatted down and looked at Gengo, unable to help but complain. The boy chuckled, picked up his coffee and drank it all in one gulp, gave Naomi a thumbs up, and then got up and left the train. At this time, all the Immortals had been summoned away by Ryotaro, and Naomi, who was the only one left, couldn't hold him back at all. So it was a good time to leave. He couldn't bear to sit here and watch others fight.

'skull'

Gengo transformed into a Kamen Rider identical to Narumi Shokichi and joined the battle. However, because the battlefield was too chaotic, Narumi Shokichi did not choose to search for Terui Ryu immediately. Instead, he cooperated with other Kamen Riders to repel the enemy. On the other side, Kamen Rider W was wielding a metal rod to eliminate the combatants surrounding him. Suddenly, a dense barrage of bullets came and cleared out the enemies around him. Shotaro instinctively wanted to say thank you, but when he saw a familiar figure, his voice stammered.

But before he could utter the word 'uncle,' Yuanxiang preemptively said:

"Shotaro-senpai, Philip-senpai, are you alright?"

"Ah... Ahaha, Gensato."

Shotaro subconsciously pressed down on his hat, his tone slightly embarrassed, but he immediately realized what he was doing and hurriedly said:

"Wait, Go, why are you fighting? Nogami isn't..."

"I'm just clearing out the outer battlefield so you can attack the main targets as soon as possible. And senior, is this still of any use?"

Gengo held up the Lockseed of Kamen Rider W and asked a question, to which Philip immediately replied:

"It's useless. It's just a teleportation device; no power resides within it."

"Then please return these cards to Tsukasa Kadoya."

Gengo immediately took out another Rider Card and handed it to Kamen Rider W. Kadoya Tsukasa was currently in the heart of the battlefield, fighting against the half-crippled Kamen Rider Fifeteen. To be honest, although Gengo was certain that he still had considerable fighting power, since so many seniors were there, he didn't need to fight so hard. He could just clear out the grunts for them and do something less strenuous.

"Alright, Xiang, leave Bataan to us. You just need to oversee things."

Shotaro Sakai took the knight card, while Philip gave instructions:

"You must not touch 'xtrene' again. I haven't figured out how to crack it yet, but I have made progress, so you must not let your situation get any worse."

"I understand, Philip-senpai. You guys go quickly. Kadoya Tsukasa doesn't have any Rider Cards. I have a feeling he'll get beaten up badly."

Gengo readily agreed, then urged Kamen Rider W on. A gust of wind blew, and the half-green, half-black rider disappeared from the boy's sight. Gengo then turned and ran towards the direction where Terui Ryu was.

"Despair is your end!"

Wielding his engine sword, Terui Ryu unleashed an energy slash in the shape of an "A," obliterating the enemy before him. He muttered coldly, then heard footsteps behind him. Instinctively, he turned, sword in hand, ready to attack, only to see the hat-wearing Kamen Rider. He froze, stunned. As Narumi Akiko's husband, he certainly knew this Kamen Rider Skull, but... ah, right, with Bataan's breakthrough of reality, many souls had returned to this world. Could it be that Mr. Narumi also...?

Thinking of this, Terujiro's throat went dry with nervousness, and he suddenly didn't know what to do with the engine sword he was holding.

"Terui-senpai, are you alright?"

"No, no, no, senior... village?"

After a few breaths, Terui Ryu, who had instinctively and desperately tried to refute, realized what was happening and tentatively asked, while Genji immediately switched to 'joker' and said softly:

“It’s me. I’ll handle these combatants. Senior, you can focus on dealing with the Bataan officers.”

"Okay, but don't push yourself. Take care of your health."

Terui Ryu wanted to say more, but hearing the explosion not far away, he couldn't care less. He patted Genji's shoulder hard, as if to transfer his strength to the boy, and then hurriedly left.

At that moment, Genji suddenly saw a very unfamiliar Kamen Rider wielding a weapon in the distance, fighting against the Bataan combatant. His movements were stiff and clumsy, suggesting he wasn't very skilled in combat. His armor was very similar to Kaito's after transforming, except it was orange-shaped, so...

"Tuo!"

With a loud shout, the descending fist storm annihilated the Bataan combatants who were trying to surround and kill the Orange Knight. Genshou landed with a front flip beside him and said softly:

"Mr. Kuzuha?"

"Yuanxiang, is it really you?"

Kouta Kuzuha said with delight:

"I just saw a knight who looked exactly like you, half green and half black. I went over to say hello, but he didn't recognize me at all. I thought..."

“That was my senior, who possessed the same knightly power as me.”

Yuanxiang chuckled as he explained, then glanced at him and said softly:

"I didn't expect the breakthrough point for the Bataan base to be in Sawame City. How come you...?"

"I want to fight!"

Kouta Kuzuba understood Gensou's meaning and immediately said decisively:

“My friends, my family, and all these innocent people are in danger, and I have the power to stop these villains, so I must stand up and protect them! Just like you, I will drive away all these dangers!”

"Hmph, what a braggart."

These words weren't spoken by Gengo, but by Kamen Rider Baron, who suddenly appeared from the side. He didn't approve of Kouta Kazuha's boastful behavior; it would be better to kill a few more monsters instead of talking. After noticing Gengo's gaze, Kaito's tone softened slightly, but he still stubbornly said:

"I want to become stronger, and these guys are just the whetstone for me. I have no interest in bullying the weak."

After saying that, Kaito rushed out, wielding the banana spear, and fought bravely against the enemy. Genji chuckled. He was right; this man was not a bad person, just a bit extreme in his thinking. After this battle, he asked the seniors to keep an eye on him and take care of him.

"Mr. Kuzuha".

Turning his gaze away, Gensou nudged Kuzunoha Kouta and said softly:

"Let's all go together and wipe out these combatants!"

"Okay! Um, just call me Kouta, 'sir' is fine..."
