In this fantasy world, be a Kamen Rider

In this fantasy world, I become a Kamen Rider. (Author: Miraculous Raiyo)

Synopsis: "Host, please collect materials as soon as possible!"

"I'm really trying my best! Don't rush me!"

"Reisen, don't run away! You're a rabbit, aren't you?"

"Huh? You... what do you want to do?"

"Look at this bottle! With your blood, I can transform!"

"And Suika! Let me use yours too! You and Tank have a really high synergy!! Ouch, ouch, ouch, I can't beat you!!"

Having obtained Pandora's Box, Yoruichi possesses the ability to create energy bottles from the blood of yokai girls. This is a brand new, stronger Kamen Rider Build, imbued with yokai power, growing up in Gensokyo!

Section 1.1. Some Garbage Starting Tips

"here it is?"

Ye Ge opened his eyes. Still adjusting to the sunlight, he shielded his eyes with his hand and slowly got up from the ground. Before him lay a dense forest, with some long-haired furballs hopping around, and occasionally a few animals, thankfully all herbivores.

"Moyu? So, this is Gensokyo?"

Ye Ge shook his slightly dizzy head and looked around. Suddenly, he noticed a black box that had appeared at his feet. It had six metal plates on it, and many empty bottles were stuck in the plates. When he saw the box clearly, he couldn't help but exclaim, "Pandora's Box!"

Night Song carefully crouched down, pondered for a moment. Although he had come to the so-called Gensokyo, in this place, ordinary people without power could only live an ordinary life, and they might even die at the hands of wild beasts or youkai at any time. He looked up at the Pandora's Box on the ground, gritted his teeth, and pressed his hand hard on it.

"We're going all out today!!"

Ye Ge resolutely placed his hand on Pandora's Box. The box immediately emitted a dazzling light, which then condensed into a black dot and merged into Ye Ge's brow. Ye Ge's eyes glazed over, his body trembled, and he slowly sat down on the ground, his mouth slightly open, his eyes flashing with fear.

"Host detected, the magic box is activated."

"Initiating modification of the host's physique, raising the danger level to MAX. Danger level combat power will be determined by the Knight Armor."

"Begin injecting nebula gas."

As a series of sounds echoed in Ye Ge's mind, black smoke suddenly rose from his body. The smoke was quickly absorbed by Ye Ge, and he struggled in agony, his cries scaring away the surrounding animals. Ye Ge felt as if magma had been injected into his body, the scalding heat spreading to his limbs and bones, his bones creaking as if he were undergoing some kind of torture.

"Is the transformation... really that painful? No wonder so many people couldn't endure it and died."

Three minutes had passed, but for Ye Ge it felt like three years. The grueling reformation was finally coming to an end, and the heat was gradually fading. Ye Ge wiped away the tears from the corners of her eyes, stood up shakily, wiped the cold sweat from her forehead, looked at her hands, and clenched them tightly.

He felt his whole body brimming with power, a world apart from the body of the nerdy guy he had been before. The muscles beneath his skin were subtly undulating, and his slender arms contained strength, as if he had been training for a long time.

"Is this the power of nebula gas? I should be able to transform now, right?" Night Song muttered excitedly to herself, trying to find the metal plate and bottle, only to discover that those things had disappeared along with Pandora's Box.

"The host has not yet collected the materials and cannot craft the energy bottle." The magic box emitted a cold voice. Ye Ge was startled and quickly asked in his mind:

What does "no materials" mean?

Like a responsible instructor, the magic box told Night Song in a cold, mechanical voice: "The host needs to collect materials with relevant attributes and mix them with nebula gas to synthesize an energy bottle through this program. The energy bottle can be used without purification."

"But I'm just an ordinary person now!" Yoru covered her face helplessly. "Where am I supposed to collect these materials? I can't possibly inject nebula gas into the bodies of the people here, can I? Yukari Yakumo would kill me." Knowing that Gensokyo would definitely wipe her out for the sake of order and stability, Yoru shuddered.

"The initial system is now being issued to the host." The voice of the magic box remained unchanged. Ye Ge felt a weight in his hand, and when he looked down, he saw a gun and a purple energy bottle.

"Transform into a smoke gun and a Cobra?" Night Song was pleasantly surprised. "I didn't expect I could transform into a Stalk!"

"Host, please be aware of your surroundings. Your shout has already attracted the attention of carnivores."

The magic box reminded Ye Ge, who was still immersed in surprise, that three wolves had suddenly appeared around him, drooling and staring at him with fierce eyes.

"Heh, fine, let you be Blood Stalk's first opponents. Although this form isn't too strong, it should be enough to deal with you." Night Song sneered, the nebula gas bringing out his belligerent nature.

Shake the energy bottle, turn on the switch, insert it into the gun, and with a "Cobra" sound, the gun flashes a purple light.

"Steam the blood." Night Song held the gun horizontally in front of his chest, watching the approaching Hungry Wolf step by step, and pulled the trigger.

"Cobra!Mist Match!Cobra..Cobra..Fire!"

A dark gray gas spread out, enveloping Night Song, and a layer of armor appeared on his body. When the smoke dissipated, the hungry wolves were all stunned. The human before them had changed.

"Then, the rules of victory have been decided!" With his signature Build pose, Night Song slowly walked towards Garou. He wasn't nervous at all. These few beasts couldn't possibly break through his knight armor, and naturally, they posed no threat to him.

The wolves began to stir restlessly. The leader took the initiative and ran quickly towards Ye Ge, opening its drool-filled mouth to bite him. With a "clang," Ye Ge's arm was bitten in its mouth.

"Heh." Ye Ge sneered, forcefully flinging the wolf away. Blood seeped from its mouth, several teeth fell to Ye Ge's feet, still stained with fresh blood, and its heart was pierced. "Is that all? Not even a weapon?" Ye Ge said casually, cracking her knuckles.

"Snoring." The other two wolves were clearly frightened. One of them slowly retreated. Just as it turned to run away, its body suddenly trembled violently. Then black gas came out of its body, and it collapsed to the ground, losing its breath. In the end, even its body disappeared.

"If you want to run away, did you ask me first?" Night Song withdrew the poison needle from her wrist. The knight armor provided by the magic box was very comprehensive, and even Evolto's poison needle was included. With this injection of poison, the wolf, an ordinary wild beast, naturally could not withstand it, and its corpse was not preserved.

Seeing that its companions were all dead and its own escape route was blocked, the last wolf suddenly became ferocious, let out a long howl, and charged towards Ye Ge without regard for anything. However, Ye Ge grabbed its neck tightly. Ye Ge looked at the hungry wolf, whose struggles were getting weaker and weaker, and asked the Magic Box curiously, "Magic Box? I remember there was an energy bottle with a wolf in it, right? Do you think these materials will work?" The materials he was referring to were naturally the corpses of the two wolves.

“The material quality is too low.” The Magic Box quickly gave the answer, but Night Song had already grasped the key point. “The quality is too low? It seems that this method will work. I remember there is a werewolf in Gensokyo, right? Would that work?” Night Song casually tossed aside the wolf’s corpse and asked.

"Sure, just one drop of that creature's blood will suffice," the magic box affirmed, also specifying the quantity for Night Song. "Really? If I have time, I could ask her for it. I'm sure a drop of blood can buy a friend, of course, a friend with real power, haha!"

Beneath the armor, Night Song revealed a malicious smile.

PS: My new book is out! Please give it your support! This is the first time I've written a story about Gensokyo and Kamen Rider Build. Of course, the protagonist's Kamen Rider armor isn't just Build; Stalk, Evolt, and other Kamen Riders will also be included!

Section 2.2. Make some extra money, and incidentally earn a bottle.

"Hmm? Someone's coming?" Suddenly, Ye Ge raised an eyebrow. He keenly sensed that a group of people were approaching. Judging from their aura, they should be human. So he deactivated his transformation, sat down next to the three wolves, and quietly waited for the people to arrive. His transformation smoke gun and energy bottle were stored in the magic box's own alternate dimension, so he wasn't worried about losing or being stolen.

"Hey! Hurry, there's someone here!" A muscular man at the head of the group saw Ye Ge and quickly waved to the people behind him. Soon, seven or eight people rushed over and helped Ye Ge up.

"Wow, you're amazing! You took down all those wolves by yourself. Looks like outsiders aren't so weak after all. What's your name?" The uncle looked at the corpse on the ground, smiled, and patted Ye Ge on the shoulder. "How are you? Are you hurt?" He spoke in Japanese, but thanks to the magic box's built-in translator, Ye Ge understood and gave a reply he could also understand: "My name is Ye Ge. I'm not hurt. I could handle those wild beasts."

"Haha, that's good!" The uncle was very happy. "This is Gensokyo. Next, we'll take you to the human settlement, the Human Village." After saying that, he reminded Yoruka, "But you have to be careful. Although the Sage of Youkai has allowed youkai and humans to coexist peacefully, there are still a few youkai that attack humans. But as long as you don't go into the Human Village, you'll be fine."

Ye Ge nodded. "I'll be careful." Then the group hastily buried the wolf's carcass and headed towards the village of humans.

As they walked, Ye Ge turned to the man behind him and asked, "Uncle, how did you end up here?" The man waved his hand and said, "We're part of the human security force's search and rescue team. We occasionally go out to the outskirts of the Magic Forest or other areas to search for outsiders who have been hidden away by spirits. We also take the opportunity to clean up some little monsters that are plotting against humans. Look at my muscles, they're definitely a symbol of strength." After saying that, the man even showed off his muscles with great enthusiasm.

"I...I see it." Yege's eyes twitched as she replied perfunctorily. The group quickly arrived at the village of humans. The uncle patted Yege's shoulder: "Yege! I'll take you to the Hieda family. They'll arrange your accommodations." Yege nodded. "Then I'll trouble you, Uncle." The uncle laughed heartily, patted his muscular chest, and led Yege into the village.

Ye Ge looked around and saw that the people there finally resembled those from the outside world. There were quite a few people setting up stalls and running shops, and sometimes you could even see a few non-humans mixed in with the crowd. Judging from their friendliness, they should get along well with humans.

The uncle led Ye Ge to a large mansion and respectfully bowed to the guards at the gate: "Gentlemen, these are the outsiders we rescued. They've come to report for duty." The guard glanced at Ye Ge and opened the gate: "Come in, as usual."

The uncle nodded repeatedly and pulled Yoru into the courtyard. Hieda Akyuu, whom he had expected, did not appear. Instead, an elderly woman with somewhat gray hair registered Yoru's information briefly, handed him a key and a number tag, and then let the uncle take Yoru away.

The uncle led Ye Ge to the designated location with practiced ease, pointing to the house in front of him, "This is your lodging."

The population density in the village is not very high, and there are many vacant houses, which provide temporary accommodation for outsiders. They can pay for the houses gradually after they integrate into the village.

Ye Ge took out her key, opened the door, and looked around the house. The house was neither too big nor too small, certainly enough for one person to live in. It was also fully equipped with many basic living facilities. It seemed that the people in the village were still very honest and kind. At least this house was a work of conscience.

"Well then, let's go see what kind of jobs we can get." With a place to stay, Ye Ge felt much more at ease. After all, having a place to stay is reassuring. On the way here, the uncle had told him a lot of things, such as finding a job to earn a living, and that people with the means could take on some jobs to earn money.

Ye Ge's residence was located on the outskirts of the Human Realm. It took quite a while to reach the so-called bustling downtown area of ​​the Human Realm. In a corner of the downtown area stood a huge wooden board covered with papers. This was where commissions were accepted.

Night Song went over to take a look. The types listed were quite varied, including odd jobs, monster extermination, missing persons, and even blood selling at the Scarlet Devil Mansion!

"Beautiful lady, why is no one taking this request?" Night Song asked the woman behind the table next to her, pointing to the Scarlet Devil Mansion's request.

The woman glanced in the direction Ye Ge was pointing and asked, "You're from out of town, aren't you?" Ye Ge touched his nose and said, "Yes, I just arrived here."

The woman sighed, "It's all because the Scarlet Devil Mansion has grown so much, with countless vampires inside. We were doing so well with our commissions, but lately the number of vampires has increased rapidly, and they've started to look down on humans. People are often being drained of their blood, so gradually no one dares to take on the jobs anymore."

Night Song frowned and nodded. Through the conversation, he roughly understood the situation in this Gensokyo: firstly, the number of vampires was enormous; secondly, there were no spell card rules here, and only the most basic combat could solve problems.

"Then I'll take this commission and eliminate the horde of rebellious tiger demons outside." Ye Ge looked at the commission, compared the cost-effectiveness, and then accepted it.

"Okay, here's your name." The woman took out a registration form, and Ye Ge quickly registered the information before heading towards the place the client had mentioned.

"Sir! Are you sure you don't want to bring anyone else? That gang of tiger demons has already killed quite a few people outside the village. Because the security force can't interfere in matters outside the village, this is just a private commission. Don't you need someone else to help you?"

Seeing that Ye Ge was preparing to leave alone, the woman quickly gave him some advice. Ye Ge turned around and smiled, bringing his index and middle fingers together to his forehead: "It's alright, the rules of victory have already been decided!" Under the woman's somewhat worried gaze, Ye Ge walked away without looking back.

The village wasn't very big. Following the map he borrowed from the woman, Ye Ge wandered around and soon left the village, heading towards his destination.

"This must be it." Ye Ge looked at the place written on the commission form, tapped the commission form, and looked around. "It's not far from the human village. It seems that these monsters are lying in wait here."

Monsters cannot harm people while inside them, but there is not such strict defense as between people inside and outside. This request was made jointly by the families of several victims, so the reward is not small.

"Hey, looks like we've stumbled upon some prey. We're in for a treat today." Before Ye Ge could even begin his search, a voice approached from afar. Four tiger-headed, human-bodied tiger demons leaped out from behind a rock, their eyes filled with bloodlust.

"It's you guys, right? You ate seven people in total." Ye Ge straightened his mask, after all, he had to hide his identity to transform.

"Oh?" The leading tiger demon squinted its beastly eyes. "Are you here to avenge them?"

"No, I'm just here to fulfill a commission. I can't control what you do, but... your bounty is quite high."

If there are many favorites tonight, there will be more updates!!

Section 3.3. Upon arrival, the sentiment is received.

Night Song picked up the transformation gun expressionlessly. He didn't have much sympathy for the victims. It was a dog-eat-dog world, nothing more. He had no right or ability to condemn the sins of a race.

The tiger demon laughed loudly, its fangs bared: "With that broken gun you're holding? It can't even penetrate my demonic energy barrier, can it? If you're going to fight, you'll need a more powerful gun!"

"Hehe, you'll see in a moment." Ye Ge shook the energy bottle, turned on the switch, and loaded it into the gun.

"Steam the blood!"

Smoke billowed, "Cobra! Mist Match! Cobra...Cobra...Fire!"

Transformation complete, Ye Ge crossed her arms and shouted at the tiger demon, "Although I'm not a good person either, let me list your sins!" Ye Ge drew her smoke sword.

"There's still armor, but I'll tear it to shreds!" The tiger demon was startled, but it didn't lose its composure. It looked at its companions and exchanged glances. Three of them ran towards Night Song.

Night Song was not to be outdone. Raising her smoke sword, she charged forward and engaged the tiger demon in battle. The tiger demon's sharp claws drew sparks from Night Song's knight armor.

Ye Ge dodged the attacks of the other two tiger demons, swung his sword horizontally, leaving a deep bloody gash on the tiger demon's body. Upon seeing blood and being injured, the tiger demon actually reverted to its original form, letting out a roar and crouching on the ground, ready to pounce at any moment. The other two also took the opportunity to close in.

"Get out of here!" Ye Ge shouted, and two enormous, quantifiable cobras shot out from the glowing part of his breastplate, biting the tiger demon that attacked from the side, and the snakes and tigers began to fight.

"I'll finish you off with this move!" Ye Ge turned the valve of the smoke sword and slashed down at the tiger demon's body. Gas filled the air as Ye Ge injected a lethal dose of gas. The tiger demon was cut in two with one strike, unable to heal itself.

"You..." The tiger's eyes widened, and it spoke in human language, but it only managed to utter one word before losing its life.
