I am Kamen Rider who reverses dimensions

But even after reaching the convergence of the earth's veins, Fujimaru Ritsuka couldn't think of any solution. Standing before the enormous cave, she pointed inside and whispered:

"Last time, Mashu and I were in this very cavern..."

"Get out of the way!"

Before Fujimaru Ritsuka could finish speaking, two dark figures flashed before her eyes. One was undoubtedly Genji, while the other exuded a violent aura. Just looking at his afterimage was enough to send chills down one's spine. However, due to Genji's timely reaction, the attack missed its mark, and the enemy was swept away by his astonishing strength.

Even with just a glance, Fujiwara Ritsuka recognized the enemy's identity. Standing over two meters tall, with long, black, seaweed-like hair that reached past his shoulders, dark skin with bare upper body, hands bound with wrist guards, strong, muscular body, bare feet wearing a battle skirt, and a crude sword in his hand that was "more like a rock than an axe," it was undoubtedly the 'Berserker'—Hercules—that she and Mash had encountered before.

However, Berserker was now enveloped in an even denser black and red aura, and his behavior showed that he had become even more insane and irrational. Most importantly, this guy seemed to have become even stronger under the blessing of 'Evil of This World'.

On the other side, Ilya couldn't help but exclaim in surprise. She felt a resonant turmoil emanating from her own magic, and the object of that resonance was none other than the Berserker who had just appeared. Only then did Ilya realize that she hadn't failed to summon the Servant, but rather that the Servant she had summoned had been dragged into this hellish place.

Now, the Master and Servant are reunited, and the contract formed during the Holy Grail War is reconnected. But this is something Illya absolutely does not want. She can sense the ominous 'evil of this world' surging within Berserker's body. Once the contract is established, she will inevitably be corrupted by that evil power. At that time, even if she is still alive, she will certainly not be 'Illya' anymore.

"Gengoku, his Noble Phantasm is 'GodHand,' which can transform his body into armor and grant him the ability to automatically revive after eleven deaths. However, if he suffers massive damage, it can also take several of his lives at once. Furthermore, this Noble Phantasm prevents Berserker from killing him in the same way."

Fujimaru Ritsuka saw the predicament Illya was facing and hurriedly stepped forward to help suppress the formation of the contract. At the same time, she informed Gengo of the information she knew. Gengo did not delay and immediately rode the wind to attack Berserker. The enemy, being irrational, had no detailed tactics and let his physical abilities swing and smash down his axe and sword. Even so, Gengo could not find a way to break through for a while. Regardless of the guy's original strength, under the blessing of the evil of this world and the singularity, Gengo in his 'Cyclone' state showed signs of being defeated in just a few rounds.

and....

Genji stared grimly at Berserker's abdomen, where a thin, long wound had been cut by a wind blade. A corresponding wound appeared on his own body as well. It was the black and red aura surrounding Berserker exerting the Noble Phantasm effect of the Evil of This World.

Most fatally, a new layer of black and red light instantly appeared over the wound on Berserker's abdomen. In other words, if he attacked that spot again, his injury would worsen.

Am I not just fighting this Berserker, but the entire singularity?

Genji glanced thoughtfully at the sky, then took a deep breath. An 'X' mark appeared behind him, and a silver ribbon flew out from behind him. Ilya's situation was dire; a swift victory was urgently needed. Therefore…

Come!

Gamble with your life!

"Cyclone! MaximumDrive!"

As the final sound effect rang out, the emerald green gale, like a dazzling aurora, painted the black and red sky into a picturesque scene. Countless wind locks wrapped around Berserker's body, restricting his movements. Kamen Rider 'Cyclone Xtreme' flew into the sky like a meteor, dancing and swirling in the gale. The aurora in the sky became even brighter as a result. In just four breaths, it was as if an emerald green sun was hanging in the sky, and the dazzling light was so bright that even Mash, who was a Demi-Servant, could hardly look directly at it.

Then... the wind stopped, and the singularity returned to deathly silence. But the next second, a deafening roar shook the heavens and the earth, and even space itself trembled. There was no wind blowing on the ground, but Berserker's body was bound by the gravity coming from the sky and flew upwards without any struggle. In the blink of an eye, the black and red figure disappeared into the emerald aurora.

Then, a fierce storm broke out!

Above the singularity, Fujimaru Ritsuka and the others saw an energy halo resembling a planetary explosion. Although it was only a vibrant green, it was incredibly beautiful. However, they were also acutely aware of the deadly danger lurking behind this beauty. Mashu hurriedly raised her shield, preparing to meet the impending impact. But Genji had excellent control over 'Cyclone,' and even with such terrifying power, he managed to avoid his companions' location.

Before the light had completely dissipated, Fujimaru Ritsuka and the others saw a bright green meteor fall. They rushed to the spot where it had fallen, only to find Genji in the crater... no, it should be said that it was an aggregate of wind that could only be described as resembling Kamen Rider 'Cyclone'. The wisps of wind barely pieced together the outline of the rider, and there were signs that it was about to dissipate from time to time.

"Yuanxiang, Yuanxiang!"

"Wait, don't go over there yet."

Fujimaru Ritsuka stopped Illya from rushing over, and with a serious expression, activated the healing magic on her Mystic Code, trying to help Genji. However, her magic passed straight through the wind without leaving any trace.

At that moment, Mashu noticed a strange little box on the ground not far away. Next to the box, a red, ticket-like object turned to dust and disappeared.

Just as the ticket disappeared, the gust of wind that was wrapped around the human figure suddenly lit up, and then Kamen Rider 'Cyclone's' body returned to solidity, and the boy under the mask let out a slightly sharp panting sound.

"So strong...too strong, it almost failed to completely kill Berserker."

Genji coughed twice forcefully, deactivating his transformation. He tilted his head, then coughed up a mouthful of blood with a "whoosh," activating his Ripple to heal his injuries. Then, in a joking tone, he softly complained to Fujimaru Ritsuka:

"How did you guys even manage to beat that thing? Twelve lives is just ridiculous..."

"Mashu and I didn't fight that thing. We just jumped over it and went to fight the boss."

As Fujimaru Ritsuka helped with her healing magic, she said in an admiring tone:

"It's really outrageous that you blasted away twelve lives in one go. Although it's not nice to say it like that, I really wish you were a Servant right now, so you could come with me to conquer the other singularities."

"Hmph, once I'm dead, you can try summoning me. If you can summon me, I'd be happy to accompany you on your journey."

Gensou laughed twice, then couldn't help but spit out another mouthful of blood. In this mouthful of blood, Ilya could see tiny pieces of flesh and blood. Without a doubt, the boy's body, which appeared to have no external injuries, was probably in a state of unimaginable disarray inside.

"Don't worry, as long as I don't die on the spot, I won't die. I just need a little time to recover. But, I really did escape with my life this time, hahaha...cough cough cough!! Wow!"

Gengo coughed up blood while forcing a bitter smile. If it weren't for the fact that in his 'Cyclone·Xtreme' form he could temporarily transform into a wind elemental and withstand the backlash from the evil of this world in a formless manner, thus alleviating some of the damage to his physical body, Gengo felt that he would really be lying flat on his back.

"sorry....."

Seeing Genji's blood, Illya burst into tears, covering her face and apologizing. She said that if it weren't for the connection between her and the Berserker, Genji wouldn't have been in such a hurry to fight to the death. His injuries were all for her sake. "We only just met... we only just met..."

Ilya suddenly froze. For some reason, she couldn't remember the scene of her first meeting with Genji. This... this shouldn't be happening. It hasn't been that long, and he was the one who saved her back then. Why... why can't I remember?

"Don't cry, this is not what I, as the older brother, should do."

As Ilya was still in a daze, she felt a cold touch slide down her face. Coming back to her senses, she saw Genji smiling as he wiped away her tears. This only made Ilya's tears flow even more freely. She didn't know why, but she knew that this person's hand was even colder than her tears, and this... was all because of her...

"Alright, alright, now is not the time to cry."

Genjiro forced himself to stand up and looked at Fujimaru Ritsuka, saying:

"What's next? What should we do next?"

"Go find the Holy Grail."

Fujimaru Ritsuka reached out to help Genji, but after seeing Illya offer to act as a little 'crutch,' she withdrew her hand and said softly:

"Generally speaking, singularities are generated with the Holy Grail as the core. Once that thing is found... Why do I keep getting interrupted?"

Fujimaru Ritsuka sighed helplessly as she listened to the shrill scream from the sky, muttering to herself as she ducked behind Mashu. But this time, it wasn't an enemy falling from the sky, but something quite familiar. Fujimaru Ritsuka tilted her head, carefully went to the crater, and retrieved the fallen object. Looking at the small stone that barely resembled the outline of a cup, she said:

"This... seems to be the Holy Grail for this singularity?"

"This thing is inside Berserker's body."

At this moment, Yuanxiang also spoke up:

"When I smashed his body, I thought it was something bad, so I kicked it as well, but I didn't expect it to be undamaged."

"Luckily it didn't break..."

Fujimaru Ritsuka muttered a soft remark:

"The Holy Grail is a powerful aggregate of magical energy; it's terrifying when it explodes. Hmm? Is it coming?"

After the Holy Grail fell into Fujimaru Ritsuka's hands, everyone noticed fluctuations in the surrounding space. Fujimaru Ritsuka hurriedly tried to contact Chaldea to teleport them back from the collapsing singularity. Mashu also grabbed Genji and Illya, one in each hand, to prepare for the teleportation.

but....

After the violent spatial tremors, Fujimaru Ritsuka, seeing the surrounding scenery blurring like water ripples, realized that the situation had taken an unexpected turn. She hurriedly went to Mash's side. The expected enemy did not appear, but after the 'water ripples' receded, she was shocked to find that her group had returned to the outskirts of Fuyuki City, back to the place where they had met Genjo.

"No, what, what's going on?"

Fujimaru Ritsuka glanced at the Holy Grail embryo in her hand and hurriedly went to lift the hole in the ground, only to find that there was no trace of her and Mash cleaning up inside. This undoubtedly indicated that they had arrived in a new Fuyuki City. At this moment, Genji thoughtfully told Fujimaru Ritsuka about the seven 'soap bubbles' he had found outside, and then he saw the Master's expression suddenly darken.

"Goetia, are you crazy?!"

Fujimaru Ritsuka, clutching her hair, cried out in exasperation:

"You're simulating an experiment seven times in one world? You're really targeting the same sheep to fleece!"

"Calm down, calm down, it's not a big deal."

Gengo smiled and patted Fujimaru Ritsuka on the shoulder, saying:

"This makes things easier for us, doesn't it? We can just go back to the Great Hollow and kill the Berserker again."

"but....."

"This time we have the Holy Grail in our hands too."

Looking at Fujimaru Ritsuka's complicated expression, Gengo chuckled and said:

"If I understand correctly, this thing can be used to provide you with magic power, then I'll leave my injuries to you."

"Gengoku, healing magic is included with the Mystic Code."

Fujimaru Ritsuka explained bitterly:

"I don't know how to do it myself, so even if I had this Holy Grail embryo, I wouldn't be able to continue the treatment."

"It's okay, I can treat myself. You just need to treat the immediate problem."

"Yuanxiang..."

Looking at the boy in front of her, Fujimaru Ritsuka hesitated for a moment, then couldn't help but say:

"Don't think you're not human."

"What are you saying?"

Gensou took a deep breath to maintain his breathing rhythm and let the ripples continue to circulate, then said softly:

"I take fighting very seriously. If I'm going to be a burden to others, I won't go to the front lines even if you send me. Besides, what's this kind of injury? It's nothing. Compared to that, it's better to leave this place as soon as possible. Who knows if the evil in this world will change in other ways?"

The logic is sound, but...

Fujimaru Ritsuka opened her mouth, but ultimately couldn't say anything. Illya also had something to say, but since Genji had already said so, she figured he wouldn't listen to her advice anyway, so she could only sigh in her heart.

"Let's treat your injuries first."

Fujimaru Ritsuka handed the Holy Grail embryo to Illya. Although she had crammed a lot of knowledge about singularities, she was completely clueless about the details of the Holy Grail, so she asked this little Grail expert to help her access its magic.

But after Ilya got her hands on it, the little guy let out a questioning sound. She drew a magic circle on the ground with her own blood, put the Holy Grail embryo into it, and after observing it for a while, she picked it up in astonishment.

The 'mystery' of this world has not dissipated, but has been stored within this Holy Grail embryo, and is undergoing further growth based on the ley lines of the singularity.

However, this is where the problem arises.

In a sense, the 'mystery' of the world is a whole, but now it has been divided into seven parts, and then it has expanded and grown in a fragmented form. What will happen in this way?

Hearing Ilya's words, everyone looked at each other, unsure of the answer. However, an ominous premonition gradually enveloped their hearts. Genji put the 'Cyclone' into the Lost Driver, picked up the Knight Pass from a short distance away, and put it back in his pocket. His eyes became incredibly sharp. He had already won once and had experience, so he was confident that he could control his strength in the next battle, suffer less injury, and then hold on until he could clear the remaining simulated singularities in one go and safely bring Ilya and the others out.

Then we'll turn this world back to its original state!

"Ilya, are you alright?"

At this moment, Mashu noticed the girl's unusual behavior and asked her what was wrong. Illya shook her head and replied softly:

"It's nothing, it's just that this Holy Grail embryo isn't very pure. It seems like there are still some Berserker memories left in it, and the mess is giving me a bit of a headache."

"If you experience any other discomfort, please remember to say so. Okay, it's time to go."

Just like before, Gengo skillfully led Fujimaru Ritsuka and the others, avoiding the walking corpses and black mud monsters, and arrived at the Great Hollow. But this time, Gengo and the others noticed something different: the trees outside the Great Hollow were showing signs of petrification. This made Fujimaru Ritsuka realize it, and her expression changed slightly.

"It seems that the final boss in each simulated singularity is different."

Fujimaru Ritsuka tapped the petrified tree and said:

"This time it's Rider. If the Servant hasn't changed, it should be Medusa. Well, she's the legendary goddess who can petrify people with her eyes. People caught by Medusa's magic eyes will be petrified on the spot depending on their magic resistance. Even if they avoid being petrified, they will still be subjected to Medusa's 'pressure' effect when she looks at them, which will suppress their abilities."
