I am Kamen Rider who reverses dimensions

The effect of the Knight Pass had disappeared. He had used up all the remaining Knight Passes in one go, only to get this short time. If he did not undo the transformation, it would be a small matter if he became a true 'blank'. The real problem was that the data and power of the two planets currently wrapped around him would be trapped here because of his 'blank' nature, which would not be a good thing for the planets.

What a pity... what a waste of such a powerful force, I was unable to unleash its full potential.

Gensou sighed. He knew very well that in the battle just now, he had simply and crudely unleashed the power within his body; it should have a more refined use, and other mysterious abilities...

Let's wait until next time, if there's another chance to use this power.

Yuanxiang looked at the spatial passage that had been partially torn open, and threw seven punches into it with all his might, sending the dark fist storm following the teleportation traces left by Goetia. If it hit, it would be a bonus; if it missed, so be it.

After calming the space in this area, Gengo returned to the planet where Illya and the others were. The moment he landed, the Kamen Rider's body suddenly disintegrated, like a robot that had not yet been reassembled and whose parts were scattered. The armor on his body disintegrated and floated, revealing what was under the armor and the pure data stream beneath. After completing the transformation, there was no physical body under this armor.

Then, the data poured out, outlining a meteor shower-like rainbow of light in the sky. Some of it turned into a gust of wind, passing through the door and returning to the Wind City, while some sank into the planet.

The scattered, graded armor pieces gradually pieced together a gaunt figure. The body, resembling a marionette, made various stiff movements, reminiscent of the word 'walking corpse.' But then, a gust of wind blew by, and the body shuddered violently. The will named Yuanxiang awakened within it, and his data-driven soul was gradually restored.

but....

What is this feeling...?

Gensou stared blankly at his palm, then looked around in a daze. How could he describe the feeling at this moment? It was as if a knife had cut Gensou's palm. He could feel the pain and knew he was injured, but in terms of his senses, the 'injury' was like a scene from a movie, and he himself was the audience watching the film on the screen.

For Yuanxiang at this moment, everything seemed unreal. All his joys and sorrows were separated from his soul by an invisible wall, visible but intangible, making it difficult for them to stir any emotion in his heart.

However, Gensou vaguely sensed that the invisible 'wall' seemed to be getting thinner and thinner, and that it would disappear after a while, and he would return to his original form.

Let's leave that aside for now and solve the world's problems first.

"Ritsuka, Illya, how is it? The 'mystery' in the Holy Grail... um..."

Genji instinctively turned around to ask what was wrong, but as soon as he made a large movement, a sharp pain shot through his entire body, causing him to groan involuntarily. The boy slightly pulled open his clothes to look inside and discovered that his body was like a broken porcelain doll that had been glued back together. Except for his hands, feet, and head, which were undamaged, the rest of his body was covered in cracks. Moreover, these wounds did not seem to be able to be healed by energy fluctuations, nor were they related to his own self-healing ability. He could only wait for them to slowly disappear on their own.

Come to think of it, this body was transformed into the Kamen Rider's enhanced skin and armor, containing such power. It's fortunate that it wasn't torn apart.

Genji chuckled self-deprecatingly, then looked up at Fujimaru Ritsuka, intending to continue the conversation, but instead saw a completely unfamiliar look in Fujimaru Ritsuka's eyes. The Master, tears welling in her eyes, cried out in an incredibly sorrowful tone:

"I...I didn't mean to, but...but...I'm sorry, I really can't remember who you are. I should recognize you, I should recognize you..."

"It's alright, that's not important for now. The Holy Grail... why hasn't the 'mystery' within the Holy Grail been revealed yet?"

Seeing Fujimaru Ritsuka's expression, Gengo wasn't particularly moved. No, to be precise, he didn't feel anything at all. He walked laboriously to Fujimaru Ritsuka's side, and just as he reached for the Holy Grail, Illya handed it to him. At that moment, Gengo and the girl exchanged a glance, and Gengo said softly:

"do you remember me?"

"Yes, I remember your hometown!"

After witnessing Fujimaru Ritsuka, Emiya, and Mashu's amnesia, Illya, sitting on the ground, anxiously gripped Genji's hand and asked urgently:

"Gengo, Gengo, I won't forget you, right? I won't forget you, right? Gengo, answer me!"

"Let's put that aside for now. You still remember me now, which is a huge help. Come on, tell me, what's wrong with the Holy Grail?"

"...It must have been sealed away."

Ilya paused for a moment, then answered the question truthfully:

"Goetia's sealing magic is so powerful that the 'mystery' inside is like it's dead, and no matter how you try to activate it, there's no reaction."

"Actually, if possible, we could try to revive the 'mystery' within the Holy Grail by destroying it."

At this moment, Emiya picked up the conversation, looking at Genji and saying:

"But as you've seen, this planet is already 'dead.' Originally, the Holy Grail could have been used as a medium to send it into the planet, but if the Holy Grail is broken, without a suitable means to guide it, the 'mystery' will only overflow and permeate the surface. Although it could restore the planet's vitality, how long can water without a source last?"

After speaking, Emiya stared intently at Genji. Although he no longer remembered the boy, he had witnessed the battle in the starry sky very clearly. The reason he explained things so clearly was that he was looking forward to seeing what unexpected methods Genji would use.

"I understand. I have an idea that we can try, but before that..."

Gengo looked at Fujimaru Ritsuka and said:

"You can contact Chaldea now, right? In that case, you should go back, otherwise you might be harmed by this planet."

"..."

Upon hearing this, Fujimaru Ritsuka remained silent for a long time without replying. Her mind was in turmoil, and every time she opened her mouth, she didn't know what to say.

"May I ask your name?"

"Gengo, the detective of Fuuto."

"Okay, we've got it covered this time."

Noticing his Master's loss of composure, Emiya stepped forward to negotiate. After speaking, he pulled Fujimaru Ritsuka and Mash along to respond to Chaldea's summons and begin the teleportation. Regardless, as Servants, they had to...

"Oh, right, take this. It's information about Goetia. I hope it will be helpful to you."

Gensou took out a USB drive he had conjured before the transformation ended and tossed it to Emiya, saying softly:

"I'm sorry, I couldn't kill Goetia completely and cleanly."

"Don't say that. Your contributions are already enough to be remembered in human history."

Emiya caught the USB drive and answered with utmost seriousness. At that moment, a flash of light appeared on Mashu's shield, and a tiny, extremely faint light drifted out from it and flew towards Gensou.

This is the power of the nameless heroic spirit within Mash. After awakening in response to the girl's wishes, this power had no chance to be used. At the moment of parting, the nameless heroic spirit recognized Gensou and gave a wisp of its power to this guardian from another world, hoping that this power could help the boy withstand one or two wounds in future battles.

After the Chaldea group disappeared, the light fell into Genji's arms and landed on the 'Metal' memory. The silver-white memory flickered slightly, but there was no change. The power transformed into a 'seed' and merged into the data. It will grow strong and flourish in the future.

"Ilya, step back."

Gensou picked up the Holy Grail and whispered instructions, but found that Ilya did not move. Upon closer observation, he realized that the child's legs seemed to have gone limp from fright. This was understandable, as he rarely had the opportunity to witness such a scene.

Ilya blushed and instinctively covered her cheeks, but she secretly watched Genji's reaction through her fingers. She saw Genji walk away expressionlessly with the Holy Grail in his hand, which made Ilya feel a little disappointed. Shouldn't he usually come and tease her a bit?

But regardless, there were still important matters to attend to, so Ilya put her hand down and watched Gensou's next move.

"Joker".

Because of his shattered body, Gengo was temporarily unable to transform. He was genuinely worried that the burden of a forced transformation would cause his body to collapse completely. So, Gengo simply channeled the power of the 'Joker' into his arm, which had fewer cracks, and then slammed it onto the Holy Grail.

The Holy Grail, unexpectedly fragile after being affected by Goetia's magic, shattered instantly with a single punch, its 'mystery' spilling out. At that moment, Genji reached into his coat, retrieved a memory chip, and activated it:

"Moon"

Luna, the Moon Goddess, represents 'fantasy' within the Memory, containing mysterious power. Although Gengo only recently acquired this Memory, its unpredictable transformations enable him to launch incredible attacks whenever it is used. Now, Gengo is using his own memories and existence as a price to initiate 'Blank Transformation,' amplifying the power of this Memory and making it a vessel to receive the 'mystery' of this planet.

In Ilya's eyes, the memory held aloft by the boy became a bright torch under the black and red sky, and all the light emanating from the Holy Grail converged into it. The golden 'rain' transformed this area into an incomparably sacred place. Then, Genji did not hesitate to insert his own memory into the earth.

Just then, the entire planet began to shake violently. Ilya looked around and saw tender buds sprouting, blue skies and white clouds, and the moment when the planet regained its vitality.

Genji noticed that the planet's 'time' and 'space' had been restored. He reluctantly rubbed the brim of his hat and looked at Ilya, saying softly:

"Ilya, do you wish none of this had ever happened?"

"Eh?"

Upon hearing this, Ilya paused, while Genji, walking towards the door, said softly:

"Do you want this planet to become like this? Do you want your parents to participate in the Holy Grail War? Do you wish none of this had ever happened?"

"Of course, if possible, I would certainly like to."

Not understanding why Genji suddenly asked such a question, Ilya answered subconsciously. Just as she was about to press Genji for an explanation, Genji, who had already walked to the other side of the door, adjusted his hat, looked at the girl, and said:

"I understand, I have accepted your request."

A smile appeared on Yuanxiang's face, but it was so stiff that it seemed too fake. The boy maintained that smile, looked at the girl in front of him, and said softly:

“Ilya, let’s meet again in the past.”

As soon as the words left his mouth, time began to reverse in the world outside the door. Ilya's uneasy expression, as if sensing something, vanished instantly before Genji's eyes. The boy quietly waited for the moment time would stop, and then...

In the past, in Fuyuki City, late at night, a sudden, violent knocking sounded at the Matou family's door. Before anyone inside could ask anything, the door was kicked open, and a young man in a trench coat with the collar turned up walked in. He stared at the old man who had just come down the stairs and said coldly:

"You must be Zouken Matou."

'Joker!'

245 Ilya, are you happy?

That night, a loud "Taku" echoed from the Matou family home. That night, a loud "Taku" also echoed from the great hollow of Fuyuki City. That night, the Tohsaka family welcomed an uninvited guest. That night, Kiritsugu Emiya and Irisviel von Einzbern were also blocked at their door by a boy. That night passed "peacefully," but the future was quietly changing that night.

In the dawn light, Gengo stood in the woods outside the Einzbern family home, looking at the silver-clad landscape before him, but his figure had vanished.

However, he did not return to the agency. After dealing with everything, Gengo was detected by the reborn world's corrective power from this 'past' and forcibly expelled from this timeline.

Whether it was because his corrective power had just been reborn and wasn't strong enough, or for some other unknown reason, Genji wasn't banished from the planet. Instead, he arrived three years later, on the very day he first met Illya. The boy looked at the almost unchanged forest outside the Einzbern family's house, adjusted his collar to cover the crack on the side of his neck, and then once again rode the wind towards Fuyuki City...

"Sister, hurry up, we're going to be late!"

On the street in front of the Tohsaka family home, Sakura Tohsaka, holding her older sister Rin Tohsaka's hand, said in a slightly hurried tone:

"Don't worry about the bicycle anymore. By the time you fix it, the whole morning will be gone."

"Sakura, don't stop me! I'll stake the reputation of the Tohsaka family on it, I refuse to believe I can't fix it!"

The girl being pulled along by Sakura Tohsaka stamped her feet and shouted in a fit of rage:

"It's just a minor chain slip, no problem, it's not a big deal, trust me!"

"cold."

At that moment, a man with a small mustache and elegant manners appeared in front of the Tohsaka family's house and said softly:

"Remember to be elegant and go to school with Sakura. I'll handle things here."

"Yes, Father."

Rin Tohsaka reluctantly lowered her head and responded, then left with her sister. Watching the departing sisters, the mustachioed man, Tokiomi Tohsaka, had a complicated expression. Both sisters possessed rare talents equivalent to miracles, but it wasn't necessarily a good thing.

Because demonic nature attracts demonic nature in return, his daughters had no other way to deal with the demonic nature hidden in their blood except for understanding and cultivating the demonic path themselves.

The Tohsaka family's blessing can only be bestowed upon one person. The person who does not become the heir will be caught up in all sorts of strange events because of their own blood, and will also bring trouble upon themselves.

If the Magic Association were to discover such an ordinary person, those guys would be happy to preserve her in formalin as a specimen under the guise of protection.

Therefore, after much deliberation, Tokiomi Tohsaka made the decision to have Sakura Tohsaka adopted by another magic family.

However, just as he made this decision, a boy claiming to be a detective broke into his house. After dismantling all his magic tricks and nearly strangling him, the boy expressed his desire to have a calm and peaceful talk with him.

Having no choice and not wanting to die, Tokiomi Tohsaka naturally agreed. What they talked about shocked him. The boy said he came from the future for Sakura Tohsaka and told him in detail about the suffering the child had endured in the Matou family in the future.

Although this was somewhat unbelievable, Tokiomi Tohsaka, as an excellent magician, naturally understood that the boy's words were indeed based on something. He immediately wanted to question Zouken Matou about whether he really had such excessive attention to his daughter, but the boy stopped him. He hoped that he would no longer have the idea of ​​adopting her and that he could let Sakura and her family grow up together.

However, Tokiomi Tohsaka could only laugh and cry as he laid out the problems his daughters were facing. In order to protect both daughters at the same time, one of them had to be adopted by another magician family. In his eyes, the only families that were reliable enough to be adopted were his aunt’s family, the elegant hyena Edelfelt family, whom he had not spoken to for sixty years and who would fight whenever they met, and his current good neighbor, the Matou family, whom he knew a little about.

However, Tokiomi Tohsaka never expected that after hearing his worries, the boy in front of him closed his eyes and his whole body radiated emerald green light. In that instant, Tokiomi Tohsaka felt an endless pressure from the boy. He seemed to no longer be human, but a collection of some indescribable power. Just looking at him, it felt as if countless words and books were flashing before his eyes.
