I am Kamen Rider who reverses dimensions

Just as Gensou was pondering the Knight Pass, he suddenly sensed an unusual aura in the wind, filled with death and despair. He turned around in surprise and saw an ominous red light emanating from the edge of the agency's 'door'. His expression hardened, and without hesitation, he grabbed his tools, pushed open the door, and went out to see what was happening in the world outside the 'door'.

Behind the door lay the scorched earth, a blood-red expanse stretching as far as the eye could see. There was not a trace of life to be found between heaven and earth. Yuanxiang reached out and gently touched the ruins beside him. With just a slight touch, the seemingly solid stones instantly turned into granular ash, clearly having been burned through.

But... what kind of flame could possibly do that?

Gensou's expression grew increasingly serious. He realized that what he was encountering this time was no small matter, and it might be a great terror no less than the Shinichi incident. However, since I was brought here, someone must have made a request to me. Where is the client?

Genji ran around anxiously, calling out, hoping for a response. At the same time, the 'wind' drifted in all directions, searching for any usable information as the boy wished, but only silence returned... and so on.

Sensing something, Gensou abruptly stopped. Indeed, there was only deathly silence in the wind, but... it seemed that some dead things were still moving unwillingly. Gensou hurried over, and after passing through a wide forest, he finally saw a castle, or rather, a castle that was already in ruins. Here, he saw a sea of ​​walking corpses like locusts, as well as skeletal monsters. This scene even made him wonder if all the dead creatures in this area had gathered here.

But there wasn't much time for Genji to think about these things. After witnessing the appearance of life, the monsters wandering on the castle ruins let out howls of thirst for flesh and blood. In an instant, their mere actions caused an earthquake-like tremor, and the sound waves even made Genji feel as if he was being pushed.

However, you're dreaming if you think you can overwhelm me with sheer numbers.

'Cyclone'

Facing the horde of zombies, Genji calmly pressed the memory key, sending it into the Lost Driver, and shouted in a deep voice:

"RiderHenShin!"

A gust of wind swept in at the boy's call, but this time the wind brought by the transformation had a hint of gray and black, which made Genji frown slightly again. This change showed just how bad the situation on this planet was.

"I'm very busy right now, everyone get out of here!"

"Cyclone! MaximumDrive!"

With a devastating sound effect, a black and gray hurricane swept away the oncoming enemy tide, crushing all those caught in its path. In an instant, black 'snow' began to fall over the castle. But Genji's movements did not slow down at all; in fact, he began to advance even more vigorously. In the air, he noticed that the zombie horde, which had been charging at him in unison, was now showing signs of splitting up. This undoubtedly meant that they had found a new target, a new life, and that might just be the client he had been searching for!

"Open it for me!"

Thinking of this, Yuanxiang roared and used his body as an arrow to break through the mountain of corpses that had been piled up to grab him. He went straight to the branching point and, after blowing away layer after layer of corpses on the ground, Yuanxiang finally saw a collapse leading underground. The situation inside was quite funny. The zombies, who were eager to devour flesh and blood, rushed too hard and got stuck in each other. In addition, the underground passage had many turns, so they had not succeeded until Yuanxiang arrived.

When Yuanxiang finally cleared a path and reached the deepest part, he saw a white-haired girl lying quietly in a huge magic circle. Her whole body was covered in scarlet patterns, as if she was using the power within to maintain the operation of the magic circle. Yuanxiang wanted to approach her, but was blocked by the barrier of the magic circle. However, for Yuanxiang, this barrier was nothing more than a matter of a casual slap.

Furthermore, after the barrier was breached in Yuanxiang, the scarlet patterns faded, and the unconscious girl let out a painful groan. Her hazy consciousness cleared slightly as a result. Looking at the emerald-green figure who had picked her up, she moved her dry lips and weakly murmured:

"Berserker...."

"Huh? What did you say?"

Are you my Berserker?

239 Singularities

Yuanxiang's English was decent, so he understood what 'Berserker' meant. He just didn't understand why the girl was saying it at this time. However, there were too many things he couldn't understand right now, so he didn't take it to heart. While using Ripple to heal the girl's body, he continued to clear out the monsters that were entrenched on the castle.

After cleaning up, he found a relatively intact house, found some rags, and placed them under the girl so she could lie down. He then silently looked outside, pondering what had happened in the world.

About thirty minutes later, the girl slowly woke up. She seemed to still be immersed in the nightmare of being surrounded by monsters. As soon as she opened her eyes, she let out a terrified scream.

At the same time, although the damage caused to her body by the scarlet markings had been healed by Gensou, the psychological shadow left by it had not dissipated. As a result, whenever she made a move, she would mistakenly think that her body was in pain and let out a shrill cry.

"It's alright, it's alright, you're safe now."

Gensou noticed that something was wrong with the girl and rushed over to hold her, restraining her limbs to prevent her from hurting herself in her frenzy. At the same time, he channeled the power of the Ripple back into her body, using the warmth to calm her mind.

"It hurts so much! It hurts so much, Mom! It hurts! Kiritsugu! Kiritsugu! Why aren't you taking care of me? It hurts so much!!!"

The girl wailed loudly, her once pretty face instantly covered in tears and snot. If it weren't for the ripples, Yuanxiang would have suspected that she could have screamed until her throat bled.

What has this child been through...?

Yuanxiang sighed with heartache. He could see the girl's problem perfectly well, but talk therapy wasn't his forte. After a moment's thought, he spoke even more gently:

"Does it hurt a lot? Then hit me. I'll share the pain with you, and it will gradually stop hurting. If you don't believe me, try it."

Yuanxiang believed that all the pain in his heart could be relieved by venting. If the girl's mind was not really broken, letting her fuss for a while would eventually calm her down and allow her to have a normal conversation with him.

And so, while enduring the girl's kicks and scratches, Gensou kept a close eye on her condition. When she seemed on the verge of collapse, he would knock her unconscious, waiting for her to wake up again. This was repeated nearly ten times. When the girl awoke again, a glint of light appeared in her eyes. She stared blankly at the ceiling, seemingly lost in thought, before finally turning her gaze to Gensou beside her and softly saying:

"Thank you."

"You're welcome."

Yuanxiang casually straightened his jacket, which had been nearly torn to shreds by the girl, tied a few knots to secure it, and then looked at her and said:

"Can you tell me your name?"

“Illyasviel von Einzbern”.

"That's a really long name. Can I just call you Ilya?"

Looking at the girl in front of him, who was as delicate as a doll, he nodded silently. Genji crossed his arms and continued to ask about the situation. But at this moment, Ilya suddenly raised her arm, looked at her smooth skin, and looked around as if she was looking for something. After searching in vain, she suddenly looked at Genji, her brows slightly furrowed, as if she was trying to establish some kind of connection with him.

Seeing her expression, Yuanxiang vaguely guessed what was going on, and shrugged, explaining:

"I'm not your 'Berserker,' just a little detective who happened to be passing by."

"I see..."

Ilya nodded and answered softly. It was at this moment that Gensou noticed a change in the child's attitude towards him. She seemed to be wary of him, and her eyes held a hint of flattery. This was not hard to understand. After all, what reliable relationship could there be between strangers? The weak child was also worried about being abandoned by the adults and dying alone.

"Alright, Ilya, now tell me where this place is, and what's with those zombies?"

Genji didn't bother explaining Ilya's thoughts; he was more concerned about the cause of the accident and wanted to try to stop the disaster from continuing.

"This is the Einzbern residence. As for what those monsters are all about, I'm not entirely sure either."

Ilya honestly told Genji everything she knew. In a sense, she was also the little princess of the Einzbern family. She was studying and experimenting in order to realize the ideals of the Einzbern family. Until a few days ago, a strange band of light suddenly appeared in the sky, and a strange red light fell from it.

From that day on, the sky began to change, becoming as filthy as it is now, and the vegetation began to wither, as if this land had lost its vitality. But the strange band of light still hovered in the sky, like a savior, illuminating this dark world.

But the band of light didn't last long. In a moment of carelessness, it disappeared as if it had never existed. And right after it disappeared, the last remaining light in the world also vanished, followed by death, death, and more death!

In less than half a day, the Einzbern family was surrounded by the walking dead. Although the Einzbern family could also artificially recreate mystery and miracles using magical means called 'magic', those corpses were not just ordinary dead bodies. In the words of the head of the Einzbern family, their bodies also contained 'mystery'. Faced with such a terrifying number, the Einzbern family, who were not very good at fighting to begin with, had nowhere to escape, so they threw Ilya into the castle's underground, making her serve as the core of maintaining the protective barrier.

It was undoubtedly a form of torture, as if countless hands were squeezing every blood vessel in her body, forcefully draining every drop of blood. If Ilya hadn't undergone the Einzbern family's magical transformation while still an embryo, she would probably have been dried up long ago. Even with Ilya as the core, the Einzbern family's castle was still breached by the zombie horde. The one who was abandoned first became the last survivor, which was truly a great irony.

"However, this disaster is indeed very strange."

Ilya looked at Genji and said softly, "The Einzbern family is also a long-established magic family with many methods. They shouldn't be reduced to hiding behind the barrier and waiting to die. Besides, when she was thrown into the magic circle, she tried to save herself, but all her magic failed. This is really hard to understand."

"Big brother, if you don't mind, could you go and search through those ruins?"

Seeing that Genji was still waiting for her to continue explaining, Ilya jumped up with a "Hey!" and ran out as she spoke. Clearly, whether Genji agreed or not, she intended to find the answer at the old site of the Einzbern family. Genji naturally did not stand idly by and headed underground in the direction Ilya pointed out.

"As expected... I told you they wouldn't just obediently wait to die on the ground."

A moment later, Ilya looked at the opening Gensou had made, muttered something under her breath, and jumped down. Gensou caught her and carefully placed her on the ground. Ilya smiled at Gensou, then eagerly began to peruse the remaining records underground, wondering what her elders had discovered. About twenty minutes later, the girl blinked blankly and said softly in an incredulous tone:

"That...this world...is doomed."

"Don't talk so nonsensically, explain the specific reasons."

Genji closed his book, gently tapped Illya on the head, and said:

"It's just the end of the world, what's the big deal? Calm down."

???

Upon hearing this, Ilya immediately felt there were too many things to complain about, but Genji's calm and composed demeanor left her speechless. She could only honestly tell Genji what she had discovered.

It's not complicated. Simply put, the 'mystery' of this world began to fade after the 'heavenly fire' fell. After the halo disappeared, this fading reached its peak, making many magical techniques impossible to perform. Only some pre-designed magical facilities could still be activated by investing a large amount of magic power.

As the 'mystery' faded, the planet was also heading towards its end, as if a fire was constantly burning this land, destroying everything on it.

"Wait, since the 'mystery' is fading, then..."

Gensho pointed to the 'black snow' falling down along the cave entrance and said:

"Then what about these monsters? Didn't you just say there was something 'mysterious' about them? Isn't that a contradiction?"

"Yes, Ilya doesn't understand why either."

Ilya frowned, tilting her head in confusion. Although she had discovered during their conversation that Gensou knew nothing about magic, using the word "mysterious" to describe many of the technical terms, she didn't think Gensou's questions were wrong. However, Ilya quickly shrugged and said in an indifferent tone:

"But it doesn't really matter."

"Ok?"

"What's the point of figuring this out so clearly?"

Ilya lay on the table, looking at Genji with innocent joy, and said:

"Since the world is already destroyed, let's not worry about it. Big brother, come sit over here. While we still have some time, why don't you tell Ilya your story? Ilya is really curious, oh my."

Seeing that Yuanxiang showed no intention of sitting down, the white-haired girl put her hand to her mouth and teased, "..."

"Big brother, you don't want to save the world, do you? Or are you just unable to accept the prospect of dying right away?"

"how?"

Gensou glanced at Illya, sat down opposite her, and said softly:

Aren't you afraid of dying?

"We've already come to this point, why should we care about death?"

Ilya blinked in confusion and said:

"There's nothing we can do about it. People often say that it's only natural for the weak to be killed by the strong. Killing and being killed happen every day, so what's so strange about it?"

"So you've killed someone?"

While flipping through the books in front of Ilya, Gensou asked casually, but the boy's disregard for life revealed in the child's words made him perk up.

"Not yet...."

Ilya had basically never left the Einzbern family's castle since she was born. Although Ilya's value to the Einzbern family was to eliminate the enemy and win the final victory in the upcoming 'war', the disaster came too suddenly. Before the original battle plan could be arranged, the Einzbern family was already finished.

"But, big brother, let me tell you a secret: death isn't actually that scary."

Ilya smiled and lay on the table, her bright eyes sparkling as she whispered:

"On the contrary, it was very comfortable. Before you arrived, big brother, Ilya was almost at her limit and was about to die. But at that moment, Ilya felt light and airy all over, and all the pain flew away. Although it was a bit cold, that lazy feeling was surprisingly nice. Hehe, big brother, if you don't believe me, Ilya can let you try. Don't worry, although Ilya has never killed anyone, I know where the body is vulnerable, and I promise you won't feel too much pain."

Seeing this angelic girl utter such absurd words, Gensho paused for a moment, closed his book, and said in a deep voice:

“Ilya, you may have misunderstood something. Death is not what you described. That is just an illusion you have in your pain.”

"Eh~~? But... um!?"

Ilya wanted to argue back, after all, it was something she had personally experienced. If it weren't for Yuanxiang rescuing her, she would have been angry at this denial. But before Ilya could finish speaking, an indescribable pressure suddenly fell on her. Every movement of her body was a struggle for survival, but it was all in vain. Her vision began to darken again, just like when she was about to die in the magic circle. But this time, what she felt was not that dreamlike experience, but a powerlessness and despair that drove her almost mad.

At this moment, everything before her eyes began to blur, which made Ilya realize that if she continued, she would really die. She reached out to Genji with all her might, indicating that she knew 'death' was not a good thing and that she could stop.
