I am Kamen Rider who reverses dimensions

"So, did your wind pick up last night?"

"It's unfolded... What? What happened?"

Seeing Homura Akemi's expression, Gengo's smile vanished as he began to realize that something unexpected had happened.

"Unfortunately, last night, right outside Xiaoyuan's window, I killed a Kyubey."

Akemi Homura said in a low voice:

"The bastard mentality of Kyubey is universal. The appearance of one Kyubey means that all Kyubeys are there and have seen everything that happened to Madoka."

"I didn't expect it to be avoided..."

Gensou scratched his head and let out a long sigh. He hadn't expected that his weakness would be exposed so quickly, allowing Kyubey to perfectly evade his surveillance.

"However, Xiaoyuan still has my possession charm on her. With that on, if Kyubey can still avoid my senses, then I might really be unable to deal with Kyubey. By the way, you said you killed a Kyubey. May I ask how you killed it? I don't seem to have any attack attributes on your shield."

Could it be close-quarters combat?

Gengo subconsciously pondered, to be fair, a shield is also a good weapon. Whether it's using the shield to strike or using the edge of the shield to injure the enemy, it's a good choice. However, judging from Homura Akemi's appearance, she doesn't seem to be very proficient in fighting techniques.

"My shield has storage space."

After Homura Akemi looked around to make sure no one else was there, she summoned the shield, swiped it, and a pistol appeared in her hand.

"I have a lot of weapons. Some are homemade, but most of them were stolen from gangsters and the military, so my firepower is still very strong."

"You... wait..."

Gensou looked at Homura Akemi with a subtle expression. Last night, while gathering intelligence, he inadvertently came across a news report that one of the Japan Ground Self-Defense Force units had been disbanded for unknown reasons, and the process of disbanding was quite intriguing. To put it another way, he was now beginning to suspect that perhaps this girl had taken all of the unit's weapons and ammunition, leaving the Self-Defense Force with no way to explain itself, and thus it was disposed of in such an absurd way.

"Those kinds of things are minor issues."

Judging from the news, Homura Akemi must have seen it too. She casually holstered her pistol and calmly said:

"Anyway, I brought the weapons for Kyubey and the witch, which is also a way of protecting this country, so there's no need to worry about such trivial matters, huh?!"

Just then, Homura Akemi and Gengo's gazes sharpened. They sensed an astonishing aura; suddenly, a witch's barrier had appeared within the school.

"Go find Xiaoyuan."

Gengo and Homura Akemi turned and ran without hesitation toward the classroom where Madoka Kaname was. But just then, the witch's familiar, a twisted Chihuahua, appeared in front of them. It was clear that the witch was going to be very violent this time, and both she and her familiar were filled with killing intent. If they didn't do something, many people in this school would die.

"I'll go first..."

"Go away!"

Faced with this situation, Homura Akemi instinctively wanted Genji to deal with the witch while she went to find Homura first. But then, she saw a black-gold light erupt from Genji's body. In that instant, an aurora-like beam of light flashed across the barrier, and then...

And that was the end of it.

Homura Akemi stared at the barrier that shattered in an instant, and at the Grief Seed that suddenly appeared in Genji's hand. She was speechless for a moment. This speed and this power, if used to deal with Witch Night, should not be a problem.

"Walk."

Genji's movements were as swift and decisive as ever, heading straight for Madoka Kaname's location. Homura Akemi, secretly annoyed that she had been so shocked that she had forgotten about Madoka, hurriedly activated Time Stop to find Madoka, but...

I never expected that even with all that, we were still a step too late...

"I really didn't expect you to be so fast."

The classroom was filled with students who had fainted from the impact of the witch's barrier. Beside Madoka Kaname stood a Kyubey, who whispered:

"As expected of visitors from another dimension, if possible, could we have a brief chat later?"

"What did you do to Xiaoyuan?"

No sooner had Kyubey finished speaking than a fist storm, so fast that even Kyubey could barely keep up, came crashing down on him. Kyubey didn't dodge and was instantly blasted into a bloody pulp. But then, more than ten Kyubeys appeared outside the window, their crimson eyes fixed on Genji, on Madoka Kaname, whose chest was gushing blood, and they said in unison:

"Come on, make a wish, become a magical girl, Madoka Kaname. Make a wish for your own life. Of course, as a sign of respect for you, even if you are male, we will make an exception and allow you to become a magical girl if you wish."

"........."

Seeing the wound in Kaname Madoka's chest that had almost completely pierced through, Gengo's face darkened completely. He had no time to pay attention to Kyubey beside him, so he unleashed the power of 'Luna' and poured it into Kaname Madoka's chest, intending to reshape a heart for her.

However, things didn't go as Gengo had expected. The heart was created by 'Luna', but when it was placed in Madoka Kaname's chest, a strange force instantly corroded the heart, preventing Gengo from giving the girl a chance to be reborn.

"Give up. The power of witches is like that of magical girls, it is all kinds of strange and wonderful. Your ability seems to be just the one that counters it. Come on, make a wish. Believe in us, as long as you make a wish, Madoka Kaname's life will surely come back."

"Brother Yuanxiang, no..."

This witch's abilities are truly vicious. Although her heart has been destroyed, Madoka Kaname is still conscious. She can clearly feel her life force draining away, and she also realizes that the enemy she has encountered this time may be beyond Genji's capabilities. After all, the necklace he gave her was almost useless before it was destroyed.

But that was the result of being targeted. Gensou no Kaze didn't notice the appearance of Kyubey, and Gensou no Tsuki was also clearly seen when he turned from illusion to reality. This was a trap set by Kyubey, and naturally, it wouldn't be broken by such a trick. The Kyubeys blinked their scarlet eyes and stared at the two people in the classroom without saying anything more, as if they were waiting for the criminals to ask to be judged, patiently waiting.

"It's alright, Xiaoyuan, you won't die."

Gengo, expressionless, knocked Kaname Madoka unconscious with a single slap. Then, the power of 'Xtreme' was unleashed, pushing the power of the memory to its limit. However, this power was not used to heal Kaname Madoka, but rather to build a solid barrier between the two of them, preventing Kyubey from interfering with the following process. Afterward, Gengo unbuttoned his shirt, revealing his cracked chest and the nascent, glowing heart. He pursed his lips, removed the heart, and quickly placed it into Kaname Madoka's chest.

At that moment, Glory was willingly sacrificed by the knight, transforming into a source of life that flowed through the tender body, dispelling the ominous curse and prolonging the nearly interrupted future. When the powerful sound of a heartbeat echoed between the houses, the mastermind behind the scenes widened his eyes, unable to believe the birth of this miracle.

"That's incredible..."

The cupids whispered in unison, watching the dissipating barrier of light and aura, and said in a flat, monotone voice:

"What is that? Such powerful soul energy! That power has perfectly integrated into your body, maintaining your physiological functions. This is truly a contradiction. Let's make a deal, Genji. Give me that power, and we will heal Madoka Kaname, and we will also... heal you."

To be honest, Kyubey's voice wavered slightly when he saw Gensou's body. Without the support of that miraculous heart, the broken body was so bad that even describing it as riddled with holes wouldn't be quite right. It was a miracle that the boy was still alive. The spreading cracks seemed to symbolize that his life was gradually heading towards the end of his life.

"........"

Gengo remained silent, only a terrifying rage burning within his chest. Grayish-white flames replaced his heart as the power of the three memories—'Skull,' 'Joker,' and 'Cyclone'—was taking over his body. Thanks to his experiences in "Kamen Rider Chronicles," he now possessed a certain understanding of digitizing his body. These three powers were enough to allow him to maintain peak combat strength, which was precisely why he hadn't used 'Luna' to create a heart for himself. The newly formed flesh and blood needed to be tempered to fit his body, but now, Gengo was unwilling to expose this weakness in front of Kyubey.

"It's a real shame, Genji. You shouldn't have been hostile towards us. We are saving the entire universe. This is just a necessary sacrifice."

Kyubey blinked and looked at Gensou, saying:

"As a gesture of goodwill, let us give you a brief introduction. Our real name is Incubator, which can be translated as 'incubator' in your Earth language."

At this point, the product of this alien civilization began to explain to Yuanxiang the situation facing this universe. In short, the second law of thermodynamics states that the total entropy in an isolated system continues to increase. If the system is expanded to the entire universe, then the usable energy in the universe will be exhausted sooner or later. That is one of the possible endings of the universe that the incubators believe to be: heat death.

In the event of heat death, there is no longer any energy in the universe that can sustain motion or life.

To avoid this outcome, the Incubator civilization invented a technology that converts the emotions of intelligent life forms (hope transformed into despair) into usable energy (magic), and the energy conversion efficiency η obtained through this technology is greater than 100%.

In other words, the emotional energy that humans generate through the incubator's technology is greater than the energy needed to maintain the brain's biochemical reactions. However, the inventors of this technology lacked emotions, so to avoid cosmic heat death, they chose Earth after conducting some investigation.

The incubators arrived on Earth, which at that time only had primitive civilization. In order to increase the human population, they began to raise humans. The feed was the resources consumed in secretly promoting the development of human civilization. What they harvested was the hope of the girls when they became magical girls and the despair of the magical girls when they became witches, which they converted into energy and recycled.

Through the incubator's explanation, Genji gradually came to understand why there were so few magical girls—

Different humans generate emotional energy with varying efficiency. Among them, teenage girls in their secondary sexual development stage are the most efficient, meaning they have the greatest capacity to transform hope into despair. The incubator selects the group with the best magical talent from among them for training, and this so-called magical talent seems to involve mysterious concepts such as cause and effect.

Therefore, the incubators did not put all humans into the machines to raise them, but instead used a VR game to stimulate humans to develop emotions. This is because ordinary people have too little value. If they were to encounter a person in a vegetative state, they would not only receive no emotional support, but also incur costs for feed. As a civilization without emotions, the incubators would not do something so worthless.

"So, Gensou, we don't know if your universe is in such a state. If it is, we would be happy to share this technology with you. If not, we hope you can cooperate with us to continue this project for the continuation of this universe."

Kyubey's words were fragmented, as Genji, still enraged, continued his attacks. But as Homura Akemi had said, Kyubey seemed inexhaustible; for every one eliminated, another would appear. Moreover, the new Kyubey would even devour the corpse of the previous one, even if it had been reduced to a pulp. As if to fully utilize its resources, Kyubey looked at Genji in a flat, monotone voice and said:

"Give up, you can't kill us. We don't die. No, to be precise, we are infinite."

Cupid, no, the Incubator, blinked his scarlet eyes, looking at the increasingly pale, lifeless boy, and said softly:

"Although I don't understand, you must be angry because your fellow human beings are being used as sacrifices. However, let me remind you, you shouldn't consider yourself the same as humans. You are stronger than them. Your form of existence is vastly different from that of humans. Even magical girls seem more human than you. So, you don't need to get angry and lose your mind, wasting your time here."

There's no need to communicate anymore.

Yuanxiang wiped the blood from the corner of his mouth. It was blood that had spilled out from the impact of the three memory units taking over his body. He didn't feel any pain, because he could no longer feel any pain. The boy stared intently at the incubator in front of him. There was no need to communicate with these emotionless creatures. The only difference between them and beasts was the difference in the intelligence they possessed. In order to free humanity from being raised by these creatures, there was only one option left: to fight to the death.

However, before the battle began, Genshou took a deep breath, seemingly having calmed down, and looked at the incubators, saying softly:

"You say you have no emotions, which is why you used this technology on Earth. Then tell me, if you had so-called emotions, would you use yourselves as test subjects?"

"Of course, saving this universe is our mission. If we could have emotions, we wouldn't choose humans, who are still inefficient creatures. We would conduct research to develop better and more valuable energy utilization systems."

"You guys are really heartless, making such a nonchalant way of talking about using yourselves as experiments."

Yuanxiang sighed, pinched the bridge of his nose, looked at the incubator, and said softly:

"I can understand what you mean a little better now, but I'm still angry and dissatisfied with your attitude towards humanity. So I'm going to attack you again. Whether this attack succeeds or fails, I'll give you a gift, a gift that's not much different from that glorious heart, as a token of my appreciation for your contributions to the universe over the years."

"Although your actions are worthless in our eyes, merely a waste of time, but..."

The incubator blinked and looked at Yuanxiang, saying:

"We have witnessed the powerful magic of one of your gentlemen, and we are very interested in it. So, as a gesture of goodwill for future exchanges, we are willing to waste some more of your time. Come on, we await your attack."

Hearing the incubator's words, Genji was stunned for a moment, then realized that Hiiragi Eriol's counterattack had actually created an opportunity for him at this moment. He smiled bitterly to himself, silently remembering this favor, then took a deep breath, and a terrible hurricane began to swirl. In an instant, the bright sky suddenly turned into a storm of dark clouds. It was noon, but the sky was so gloomy that it was almost impossible to see one's hand in front of one's face.

“Impressive control, truly fascinating. Although we have already copied your data and studied your dynamic modules, it still feels amazing to see you do this with our own eyes.”

The incubators sat calmly, offering their comments as if they had merely come out for a picnic and encountered wondrous clouds. Then, as expected, Gensou's attack arrived; powerful wind blades instantly sliced ​​through all the incubators in the area. Then, in the next second, before the hurricane and dark clouds had even dissipated, new incubators reappeared from an unknown space, using unknown methods, just as before, devouring their own corpses. Then, they raised their heads, looked at Gensou, and said:

"Alright, the attack is over. Now let's move on to the next topic. Regarding your gift, we'd much rather have that legitimate way to travel through time and space. We'd love to see the wonders of other universes. We hope you can grant our request."

"That won't do."

Township Chief Yuan let out a breath, looked at the incubator, and said softly:

“I’ve already given away my gift, how can you just change it like that?”

"It's been sent out?"

The incubator paused, seemingly surprised by the answer, blinked, and said softly:

“We haven’t received that. Although lying is a basic instinct for humans, you have surpassed humanity, so you should communicate with sincerity like us incubators.”

"Haha~~~ Here's a joke: Incubators treat people with sincerity."

However, upon hearing this explanation, Gensou's face revealed an extremely mocking expression, and he looked at the incubator and said softly:

"Do you really think you're something special?"

"you!!!"

Suddenly, the incubators' voices rose, a stark contrast to their usual nonchalant demeanor. Then, in the next second, without Yuanxiang needing to remind them, the incubators realized something was amiss. They immediately stopped what they were doing, exchanged glances, and muttered to themselves:

"Anomalies detected, data not in line with the sequence detected, instability detected in the organism... Gensou, what did you do?"

What did you do?

Naturally, the 'virus' was mixed in with the wind. It must be said that the deceased Dan Kuroto was truly a genius, able to arrange the bugster virus in an orderly manner, turning that unstable thing into a game-like existence, spreading while maintaining stability. Gengo, without any hesitation, copied the same approach. Although he did not have the bugster virus on him, 'Cyclone' had memorized the programming scheme. At this moment, 'Cyclone' took over Gengo's body, corresponding to the boy's soul. Therefore, the billions of malice that he sealed deep inside also came into contact with 'Cyclone'. It was through this that the virus called malice spread to the corpse of the incubator. After being devoured by the new incubator, it entered the incubator's mental system.

And now...

'ark!'

Gensou took out a memory containing Ark data, smiled at the incubator, and then pressed the button. This was a power born from malice, and it was perfect for awakening the evil thoughts that had already infiltrated the incubator.
