In this fantasy world, be a Kamen Rider

Watatsuki Yorihime summoned a powerful god to shake Watatsuki Toyohime away from Yakumo Yukari, relieving her crisis. She glanced worriedly at Yoru's location. Although both of them could feel that the contract still existed, they would rush to her aid without hesitation if Yoru was seriously injured.

"Cough cough, how can it be so strong?"

Amidst the smoke and dust, Ye Ge coughed twice, swallowing the metallic taste in his mouth. When had he ever been so disheveled? Ever since he obtained the Black Hole Trigger, even the Dragon God had to be crushed under his feet, and the world was at his mercy. But now he had actually been injured by Killbus, and the armor on his chest was damaged, with six hideous wounds appearing on the armor.

"The next strike will finish it!"

Seeing that Night Song was not defeated, Killbus shrugged, gripped the joystick tightly, and started spinning it rapidly. Night Song did the same. Killbus suddenly accelerated, leaving afterimages in its wake, and then spat out extremely sticky spider silk. The silk formed a web shape, gathering towards the center to bind Night Song.

Night Song forcefully opened the black hole, blocking the outer spider silk. He quickly retracted his leg, and his body spun rapidly in the air, forming a black hole himself. Killbus paused upon seeing this, and forcefully pulled the spider silk, actually pulling Night Song towards him. Then, he flipped his body and delivered a defensive kick with an inverted hook.

Space trembled, creating thick ripples that even shattered Watatsuki Toyohime's abilities. With her azure eyes fixed on the direction of the two's battle, she abandoned Yakumo Yukari and Watatsuki Yorihime and flew straight towards that spot. Yakumo Yukari and Yorihime exchanged a glance, not daring to be careless, and followed behind her. But just as they made a move, a black hole suddenly opened in front of them, enveloping them both before rapidly shrinking them to nothingness.

The ripples in the space gradually subsided, leaving only Killbus in the arena. She lowered her head, looking down at the ruins of the royal palace, and suddenly stomped her foot angrily, causing the entire ruins to tremble three times with her movement: "Damn it! Damn it! He got away! We were so close to getting Pandora's Box back!"

Watatsuki Toyohime stood quietly behind her, waiting for Killbus to finish venting. She was the most obedient doll, never arguing or questioning, faithfully carrying out orders. Killbus turned around, deactivated her transformation, narrowed her eyes at the expressionless Watatsuki Toyohime, and uttered a chilling sentence: "Immediately summon all corrupted smash!"

……

Inside the black hole space, Yukari Yakumo and Yorihime Watatsuki were swept up by a black energy tornado and sped through the passage. The surrounding turbulence made it impossible for them to open their eyes. If it weren't for this energy vortex protecting them, the two would have been lost in the universe long ago.

After flying for an unknown amount of time, the space ahead gradually brightened, and the two of them were pulled out of the black hole. The black tornado released them and crashed heavily onto the ground beside them, kicking up a large cloud of dust. Yukari wiped her face and rushed over, only to be shocked to find that Yoru was lying there at some point, with a terrible scar on her chest.

"Quick! His breathing is very weak!"

The two instantly understood that it was Yoru who had led them to escape the moon, traversed the vast interstellar space, and returned to Earth. However, this was not Gensokyo, but the outside world. Just as the two were at a loss, a green light appeared, and the Dragon God appeared beside them, solemnly bending down to check on Yoru's condition.

"He actually suffered injuries of this severity?"

Dragon God gasped. She had personally witnessed Night Song's strength; he could easily suppress even the world's will. How could a Kamen Rider with the power to destroy everything be in such a sorry state? Night Song's eyes were tightly closed, completely lacking the composure and calmness of a true god of the world. He was barely breathing, and if it weren't for the faint breath he still had, the three of them would have thought he was dead.

"Quickly take him back to his own world," the Dragon God ordered. Watatsuki Yorihime looked troubled. She had no idea how to get to Yoru's world. He was unconscious, and no one could open a passage for them. However, Yakumo Yukari seemed to have an idea. She waved her hand and opened a gap, carrying Yoru into it.

"It's alright! I am his familiar, and Gensokyo is built on the world of the Dragon God, so I can travel freely through my gaps!"

As Yukari Yakumo flew swiftly, she explained, and soon they flew out of the gap and arrived in Gensokyo. As soon as they returned, the surrounding spiritual energy surged violently, rushing towards Yoru from all directions.

"Hmm...did we escape?"

As his consciousness gradually cleared, Ye Ge opened his eyes in a daze and found himself lying on a white hospital bed. There was a faint medicinal fragrance in the air. He tried to sit up but failed. All the bones in his body were broken, and his bones were rapidly repairing themselves, but it would take time.

"As expected of the gods of Gensokyo, the damage that almost killed him was healed in just ten seconds."

An envious female voice came from the side. Yege turned her head, and beautiful silver hair came into view. Yagokoro Eirin was sitting in a chair, having just poured half of the medicine in her hand. Yakumo Yukari was standing on the other side. Seeing Yege wake up, she breathed a long sigh of relief and showed a relieved smile.

"You're awake? How are you feeling?"

Where am I?

Yege took a few deep breaths, and his injuries healed. He sat up, looked around, and was surprised to find himself in Eientei.

"What a convenient ability." Yagokoro Eirin touched her face and sighed. Yoru's recovery speed was beyond imagination. The fatal injury that could kill even a great youkai was almost completely healed in an instant. You should know that as soon as Yakumo Yukari entered Gensokyo, she moved him to Eientei. The whole process took less than ten seconds, and Yoru is now as good as new.

This is the power of the world. No matter how badly injured you are, as long as you return to your own world, emptiness, serious injury, mental trauma, or exhaustion will all be swept away. In fact, Night Song's physical injuries only took three seconds to heal; what really took time was the recovery of his mind. If Killbus hadn't inflicted such severe injuries, he would have woken up the moment he returned to Gensokyo.

Where did you all go?

After seeing that Yoru was alright, Eirin Yagokoro finally asked the question that had been bothering her: Who could have injured a true god of the world so badly?

"We went to your homeland, the moon."

Section 234, 229. Every cause has an effect.

The air suddenly froze, and the medicine in Yagokoro Eirin's hand fell to the ground. She was stunned for a long time before finally shaking her head with a complicated expression: "Impossible. Even Tsukiyomi doesn't have the strength to contend with the Dragon God, let alone injure Yoru to this extent." Having lived on the moon for so long, Yagokoro Eirin knew the Lunar Capital's combat strength like the back of her hand.

“Tsukiyo is no longer here. She has been possessed by a creature called Killbus, and now the entire Lunar Capital has been corrupted.” Yukari Yakumo sighed, a hint of fear in her eyes. “Moreover, her power surpasses that of the Dragon God and even Yoru. If he hadn’t led us to escape in the end, we might already be dead there.”

Night Song gave a bitter smile. In the final moments of the kicking exchange, he shamefully chose to flee. After Killbus kicked his armor to pieces, he used all his strength to escape into the black hole, taking Yakumo Yukari and Watatsuki Yorihime with him.

“Evolto, you should tell me the truth.”

Yege patted her chest and summoned Evolto. Since Yege had taken the brunt of the damage, Evolto was in relatively good condition. She flowed out of Yege's body and transformed into human form. Looking at Yege lying on the hospital bed with some heartache, she took a deep breath and slowly began to speak:

"Killbus is my sister, and also the Queen of the Blood Star."

"She is a very crazy person, forever obsessed with destruction and devastation. My home planet Blood Star was also destroyed by her. At the last moment, I took the Evol Driver and Pandora's Box to escape, but I was also hunted down by her. I have been wandering in different places, looking for a way to survive, and then I met the Knight's Will."

Ye Ge frowned, realizing that things weren't as simple as he'd imagined: "So, Evolto, you're not just a simple artifact spirit, but a true Blood Star person, right?"

Evolto nodded. There was no need to hide anything now. "I made a deal with the Kamen Rider Will. It asked me to work for it and turn Pandora's Box into the Build system. Then it asked me to act as a guide and helper to support Kamen Rider Build or Kamen Rider Evol. After that, I came to this world. I thought I had avoided Killbus, but I didn't expect that she had also crossed over to another world."

After saying that, Evolto suddenly stood up, lowered his head to Night Song, and said with trepidation and guilt, "I'm sorry, Night Song, for telling you this only now."

A hand gently stroked Evolto's head, its warmth filling the air. Evolto looked up in surprise to see Yoruka smiling as she stroked her head, her voice soft: "Don't blame yourself, Evolto. You didn't know Killbus would come here, did you? Even if your background isn't simple, I won't hate you. You're mine, you can't run away!"

Evolto bit her lip, her eyes reddening slightly. She softly hummed in agreement, then leaned against Night Song's window, burying her head in his arms, greedily inhaling his scent. This man was the end of her destiny and the beginning of a new one. She wanted to stay with him until the end of the world.

"Ahem, I've had enough of this dog food. Can we talk about serious matters?"

Eirin Yagokoro's forehead creased with a 'well' shape as she watched the two of them flaunt their relationship. Finally, unable to bear it any longer, she suppressed her urge to break them up and shattered the ambiguous atmosphere: "That Killbus you mentioned, is she really stronger than the Dragon God?"

Evolto straightened up and nodded seriously: "Killbus is the Queen of the Blood Star. She has hunted countless planets and absorbed their power. She once surpassed the ancient great monsters, and now she has even absorbed the lunar will under the Dragon God and devoured the power of Tsukiyo. She has become an extraordinary being. Even Yoru-chan can't defeat her now unless Yoru-chan also goes down this path and keeps devouring planets to gain power."

Silence fell over the room again as everyone fell into deep thought. An existence capable of hunting planets was like a fantasy to them. The oppressive atmosphere was broken when the door suddenly opened, and Watatsuki Yorihime rushed in anxiously: "Yoga, are you alright?"

"Wait a minute! Your Highness!" Reisen's anxious voice came from outside. With tears in her eyes, she looked at the people inside, then let out a soft "uh," squatted in the corner, hugged her ears, and trembled.

"Yoru! What kind of behavior is this?"

Eirin Yagokoro frowned and reprimanded her. Yorihime Watatsuki instinctively shrank back, saying, "I'm sorry, Master." Even though she hadn't seen Eirin for so many years, the deep-seated awe she felt still made her fearful and hesitant, but her gaze towards Yoru was still full of concern.

Yoru waved to indicate that she was alright, and then said to Yagokoro Eirin, "The moon is now clean, and all the moon people have been polluted by nebula gas. They have lost their minds and become walking corpses, including your two apprentices, Watatsuki Yorihime and Watatsuki Toyohime. Yorihime has become my familiar and has survived, but as for Watatsuki Toyohime, I have no strength to save her."

Eirin Yagokoro lowered her head, her nails digging into her flesh. Although she had betrayed the Lunar Capital for Kaguya, her feelings for her apprentice remained. Hearing the news that Toyohime Watatsuki was being manipulated also made her very upset. She suddenly stood up, bowed to Yoruka, her silver hair swaying gently: "Mr. Yoruka, could you please rescue Toyohime? Although she is an enemy."

Yoru paused for a moment, his gaze sweeping over Eirin Yagokoro's face before finally settling on Reisen, who was pretending to be in the background but actually spying on him. He suddenly smiled, pointed at Reisen on the ground, and said, "Reisen-san, could you come here for a moment?"

"Huh? What? Me?"

Reisen perked up her ears, seemingly somewhat disbelieving. Yoru smiled and nodded, and Eirin Yagokoro also gestured with her eyes. Only then did Reisen reluctantly walk over, looking nervously at Yoru. Her human friend, whom she could once treat as an equal, had now become a god of Gensokyo, and she didn't know how to treat her for a moment.

"Don't be nervous." Yeka patted Reisen's hand to comfort her, then said to Yagokoro Eirin, who was equally puzzled, "Miss Eirin, you may not know, but I once made a promise to Reisen. As a reward, if she needs my help, she only needs to say the word, and I will come as soon as possible."

"In other words, if Reisen makes the request, I will definitely accept it."

Section 235, Chapter 230: The War That Is About to Begin

"Reisen, you've been keeping this a secret for a long time. When will it be?"

Eirin Yagokoro looked at Reisen with an unprecedented gaze, never expecting that Eientei had such an important bargaining chip, which Reisen had never mentioned before.

"Huh?"

Reisen was so frightened that her ears perked up, and she frantically waved her hands, "Master! I really didn't! Mr. Yoruka just..."

Startled, Reisen became incoherent, and even Yukari Yakumo's gaze changed, scanning Reisen and Yoru's faces, her meaning practically written on her face: When did you two get together?

"Ugh! Don't look at me!"

Knowing she was only making things worse, Reisen grabbed Yoru's hand with teary eyes, looking at him pleadingly, unaware that this only made Evolto, who was standing nearby, fume: "Mr. Yoru, please explain this to me!"

Yeka patted Reisen's soft little hand with a wry smile, said a few words of comfort, and then explained, "Reisen helped me a lot when I first entered Gensokyo, and even selflessly gave me her blood. Without Reisen's help, I probably wouldn't have made it to today."

Yoru was genuinely grateful to Reisen. He wasn't exaggerating. Gensokyo didn't have many materials to make Rabbit Energy Bottles, and Inaba Tei couldn't just give them to him directly. So Reisen's dedication allowed him to smoothly get through the development phase. It was then that Yoru made his promise.

"In any case, it's great that you're willing to help, Yoru." Yagokoro Eirin breathed a sigh of relief. No matter what happened, Yoru's willingness to help was the best outcome. In fact, she didn't know that even if Yagokoro Eirin hadn't made the request, Watatsuki Yorihime would have found a way to save her sister.

"Have you finished catching up on your old flame?"

The Dragon God suddenly appeared in Eientei's hospital room, solemnly patted Yoru's bed, drawing everyone's attention. She pointed to the sky: "Just now, the moon has already sent out its troops."

"what!"

Eirin Yagokoro stood up abruptly, staring at the Dragon God in disbelief, unable to maintain her composure as a sage: "The Lunar Capital has been closed off for a long time. They utterly despise the filth on the ground, and would never descend to the surface unless absolutely necessary!"

Throughout history, the Lunar Capital has sent envoys to Earth very few times. The only recent instance was when they brought Kaguya home. Of course, those envoys have all been killed. The lunar people loathe the filth on Earth and find it disgusting to be there, because life is filth to them.

"But the moon is no longer clear, is it?"

The Dragon God glanced at Yagokoro Eirin, but the pressure of the world forced her to sit back down, cold sweat pouring down her back. She had almost forgotten that the person in front of her was the Dragon God. Even though she had been defeated by Yoru, she was still the terrifying being who could stir up the world.

The Dragon God shook his head and continued, "I have observed that the spaceships on the moon have begun to move. I don't know why, but they are not moving very fast. They are expected to reach the ground in less than a day. If the so-called gas causes an infection, not only my world, but also Gensokyo will not be spared."

The Dragon God made it very clear that Gensokyo exists inside the Dragon God's world, and Killbus has already set its sights on Yoru, wanting to take over Pandora's Box. She is the one who is implicated, but she also knows that Killbus will never let go of the will of her world. In other words, they are now in the same boat.

"But her power is too strong. Can we really win?" Yukari Yakumo clenched her fists. Killbus, which is based on hunting countless planets, is even at a disadvantage in Yoru's black hole form. Who in this world can defeat her?

"No, there is another way."

Night Song threw off the blanket covering him and stood up from the hospital bed. He had fully recovered long ago. He casually grabbed the Dragon God's hand and slowly said under the expectant gazes of everyone, "If I can create a more powerful knight armor, I should be able to defeat Killbus, but I need the corresponding materials."

What do you need?

Yukari Yakumo asked urgently, "Now is the time for Gensokyo's survival, and no one should be stingy with their blood."

"Let's go to the Scarlet Devil Mansion."

……

Half an hour later, Remilia huddled in the corner, trembling and clutching her hat. Izayoi Sakuya glanced at her young mistress, wiped the bright red blood from under her nose with a handkerchief, and looked at Yoruka, who was embracing Flandre, with a helpless smile: "Mr. Yoruka, what brings you to the Scarlet Devil Mansion with such a grand entourage?"

Behind Night Song followed Eirin Yagokoro, Yuuka Kazami, Yukari Yakumo, and many other top figures from Gensokyo, as well as a powerful black-haired woman. As soon as they entered, Remilia flew out with an arrogant expression: "What brings you to the Scarlet Devil Mansion in Laos?" Her domineering attitude earned her a magical volley from Yuuka.

"Don't go too far."

Night Song gave a helpless instruction, and Yuuka then restrained her strength, but she still managed to blast Remilia into a mess. Fortunately, vampires have strong regenerative abilities, and she recovered after a while. However, Yuuka's terror still left a psychological scar on her, and the unruly fruit bat obediently huddled in a corner of the living room, crouching and defending herself.

Yoru briefly explained the situation to Sakuya, who readily agreed after understanding, "The Scarlet Devil Mansion is also part of Gensokyo, so it's my duty to do this. But... why did you come to the Scarlet Devil Mansion, Mr. Yoru?"

Ye Ge gave a mysterious smile and waved to the side. A gasp rang out, and a green figure flew to his side. Ye Ge affectionately grabbed her shoulder. "I've come here genuinely seeking help, haven't I, Master Mei-Ling?"

The long, drawn-out sound made Hong Meiling shudder. She waved her hand with a bitter face and said, "Stop cursing, stop cursing. It's too embarrassing to say that the teacher is weaker than the disciple."

"Ahem, stop joking around. I'm here this time because I need Master Meiling's blood to make new knight armor." Yege put away her joking expression, released Hong Meiling, and pleaded sincerely.

"Huh? But didn't we borrow it last time? Was it useless?"

Hong Meiling was a little stunned. Ye Ge had borrowed from her once before. Could it be because there wasn't enough? Ye Ge shook her head without explaining further. She directly took Hong Meiling's finger, and the blue light at her fingertip flashed. She pricked a small cut on Hong Meiling's finger, and blood slowly flowed out. Ye Ge suppressed her self-healing, allowing the blood to continue flowing.
