Demon Inside C1

Basically I watched Kamen Rider Revice and thought of this story idea.

I own nothing!

:Story Start:

Back story

In this world not everyone is born equal.

It started in China when a young child developed the ability to glow in the dark two hundred years ago. Over time the majority of all of Humanity gained the abilities named Quirks. This reached a point when Quirk supremacy became the tipping point as a group of Supremacists known as GiFu and discovered an ancient artefact that they weaponised to and proceeded to release a toxin into the atmosphere that only affected those without a Quirk, the weapon was not stopped in time for the bio weapon to destroy most of the Quirkless population was killed only leaving one percent of Quirkless Humans alive and with the actions of one hero ensured that no more people would die at the cost of the new hero.

The name of that hero... All Might.

The Present-thirty years later-(Izuku aged 20)-Mustafar-Hoth Bathhouse

Sitting at the desk of an old bathhouse a green haired man with four spots on each cheek wearing loose clothes of a bath house worker uniform. The bathhouse was not busy as he looked over his phone, reading about Japan's number one hero, Endeavor and his sidekick Duality was recorded stopping a forest fire using his fire to control the direction and what burnt in a forest fire, while Duality created a glacier in the middle of the fire before melting it into water to flood the area. The man sighs before looking over some of the other heroes finding some minimal villains before he changed his feed to the Government news and he could only smile seeing reports of friend of his apparently being rewarded for their actions against the Neo Gifu organisation.

An older but youthful man walked into the bathhouse holding a basket with supplies walked over to the register and asks, "Hey, Izuku working alone today?"

The green hair man also known as Izuku shakes his head and says, "Yeah, ah the boss and his wife wanted to get away for the weekend. Something about not having much time left. How are you Mister Kirazaki?"

The man was wearing lazy clothes and glasses as he appeared worn out, "You friend is doing well with us. Though I have had a breakthrough in our weapons development. Just need a candidate to test it out. Are you coming to the awards ceremony?"

Izuku frowns before saying, "I am keeping an eye on the business until the Owner returns."

Kiraraki nods before saying, "Of everyone who should go, you are definitely needing to go," Izuku nods at that before Kirazaki smiles and says, "Which is why I have booked the Bathhouse tonight for a private function."

Izuku looks at him like he is insane, "You are crazy," as Kirazaki smirks before heading inside.

Izuku returned to looking at his phone to see reports of Neo Gifu using creatures to attack people. A big part of what happened years ago during the 'Quirkless Purge' what remained from the Gifu organisation used their knowledge of Quirks and other unknown research to create literal monsters. Most with animal appearances while others are known as Nomu's that are mindless monsters that follow orders to the letter.

Izuku stands with some slight difficulty, like he was walking through water his entire life. Izuku sighs as looks at himself in the mirror as he looks at his pale eyes, a side effect from the Quirkless Purge. Ever since that time thirty years ago, those without quirks were born with a this to show their Quirklessness as a simple physical mutation, many believe that the Quirkless should be considered an endanger species less than human, while others just feel that the Quirkless should be ship off somewhere so that they don't remind people of all the tragedies of the past. For Izuku it was somewhat more painful as both his parents gave him up to the Government Support units to ensure that Izuku got all the support that he needed. The issue was that the organisation that was meant to support him was actually a group that wanted to make weapons and was caught rather quickly.

Izuku had gone back to his parents afterwards only he found he could not stay with them, as they treated him like he was made of fragile glass. Eventually he started looking for jobs until he found an elderly couple willing to hire him and then finding those who were with him during the fake government organisation. Getting friendly with the group and even starting an informal support group over the years.

Izuku sighs as he takes a seat again reflecting on everything while looking at an image of one man who sacrificed everything so that he and many other could be alive this day. Izuku was silent before heard a voice that caused him to look up expecting to see another customer only for the room to be empty, "Wow, you are lonely."

Izuku stands again and looks over the counter to find whoever was talking as he asks, "Hello?"

"Behind you," Izuku looks behind himself and he sees a floating spectre attached to his body with an ethereal tether for legs. "Nice place you got here. But this is not the dream you always strived to complete." Izuku backed away from the apparent ghost before falling over the counter backwards and was upside down with his feet over the counter. Izuku groaned while the ghost looked at Izuku's phone on the counter and says, "Oh Look Kacchan has been arrested again."

Izuku blinks before standing and grabbing his phone and groans at the sight of a blond haired exploding hand quirk from his childhood apparently being fined and sued for battery. Izuku groans and says, "At this rate, not even being able to fight the Nomu's by himself will be enough to stop him losing his Hero License."

The Ghost hums with his arms crossed, Izuku started to notice features such as a black body, while head, blue mask and giant cat like blue eyes. The Ghost says, "Maybe he should retire," which was a fair idea as in Japan's hero rankings, Kacchan was about dead last in popularity. The Ghost then goes on to say, "Why don't we go have some fun," getting a groan from Izuku. Unaware that Kirazaki was listening to him and he had to hide a smirk.

Kirazaki waited ten minutes allowing Izuku to calm down enough from his freak out that no one would know unless they saw it. The Ghost continued to whisper to Izuku as Kirazaki placed a invite to the reveal that night.

The invite was labelled with the Global Defence Force, the task force focused on fighting global threats.

Unknown Location-Neo Gifu Base/Night Club-That moment.

In a building that was quite literally a night club with dancing and drinking of people that were clearly Quirked and were members of Neo Gifu. Partying in the lair of the most dangerous organisation since it's predecessor. Of coarse that is understandable considering who was in charge these days as on stage the three leaders arrived dressed as blue and green bull fighters with the woman wearing a red flowery dress. The one in green and without the oversized hat, spoke to everyone, "You have all been suppressed by those who consider you lower than them. We have taken their weapons they created to stop us and it is time! To take our rightful places as the rulers of this world!" and he begins laughing loudly while the two with him had honest smiles for unknown reasons. Before revealing a strange stamp that he slammed on the ground creating black and white Foot soldiers as a couple patrons accepted a stamp each and proceeded to stam down on their chest creating a paper contract that wrapped around an invisible entity creating and animal like demon.

Behind the three leaders a man wearing a bartender's uniform and has purple smoke for a head stepped forward and says, "My master has agreed to let you take a High Spec Nomu for your attack at the Press Conference." Causing the three to smile as a muscle bound black creature in tan pants an exposed brain over a bird like face stepped out the new figures portal.

With Izuku-Outside the GDF Press Conference.

Izuku gave his invite to the Press Conference at the sign in desk to receive a guest pass as he clipped it to his shirt as his satchel that rested on his left hip as he walked inside. Though he froze at the sight of different heroes in the area. Though Izuku could only stare in shock at the sight of a couple.

Uravity, Quirk Zero Gravity, everything she touches with her finger tips until she presses them together. She was wearing a pink and blue bodysuit, with helmet, gloves and boots to assist with her quirk.

EarphoneJack: Quirk Ear Phone Jack, she can plug special earphone cables attached to her ears that she connects to special speakers to generate soundwaves paced with her heart beat and special directional microphones that lets her listen long distance. Her costume was a punk rock outfit that concealed her special speakers.

The crazy part about these two was that now that he saw them in person outside of their hero work as they were regulars at the Bathhouse. Not that they weren't famous in a sense, they were members of Class 1A the year they introduced the Boarding school concept to the number one hero school in Japan back when the League of Villains made their first appearance and was soon followed by the Hosu incident. Though all of this was second fiddle to the fact that members of that class had three members in the top ten heroes with EarphoneJack in Tenth while Uravity was Third.

For Izuku though he saw and oppertunaty as walked over and shyly pulled out his journal and asks, "Could I get your autographs?" directing the question to the two.

Unfortunately the Journal was taken by a blonde boy wearing a gentlemen's thief outfit. This was the Copycat Hero: QuirkThief. His Quirk lets him copy other people's quirks and apparently learnt how to use their Quirks better. The issue was that he was second to last in popularity and Hero rankings that Izuku actually forgot who he is. "I would be happy to sigh your journal," and writes his name as large as possible for the page over a sketch of Uravity that Izuku wanted her to sign.

Izuku expected to get the journal back from QuirkThief only as the Press conference began he walked inside with it and Izuku would find it later in a knocked over trashcan.

Inside Izuku found a seat in the middle as several GDF soldiers wearing white bodysuits a simple dark grey GDF on their backs, each armed with what appeared to be a bright blue touch screen cell phone. Izuku noticed one of the soldiers spot him with widened eyes before Izuku simply waved at him before the Press Conference began. Basically it was a review on what happened during the Quirkless Purge only it also reveals one of the items that they believe was used in creating the original Bio-Weapon a strange demonic looking stamp.

Kirazaki then took the stage after being introduced and says, "I have been authorised to announce a global secret," this had many gasps from the press, heroes and guests at the conference. Kirazaki continued, "The bio-logical plague that was used thirty years ago was created using two items, the Dark Stamp and the statue of Gifu," everyone gasps again, "They took their name after the statue and stamp affected their organisations' leaders. Anyway, It has been discovered that this new group have started using the power of these items to create the Demons that have been appearing around the world alongside the Nomu. Today I am here, to reveal my greatest weapon," beside him a box was wheeled over with a glass face, "The Revice Driver, which will allow the user to fight these demons with their own power," inside the glass case was a purple belt with slot and stamp pad, along with above the device was a metal stamp with a T-Rex on the side. Kirazaki then continues, "I will also be reveiling it's user," he did not have as much enthusiasm for this part of the announcement, as QuirkThief and a high ranking soldier of the GDF stepped forward to claim the driver.

Unfortunately for everyone Neo-Gifu arrived and smashed a wall down revealing a couple Animal Demons and multiple minions being led by the three leaders and Nomu directly behind them. The one in green spoke up, "We are the Deadmen! This world is ours!"

With that the heroes engaged the Deadmen attacking building, though they were being taken down by Nomu while the GDF struggled with the Deadmen minions. Izuku was knocked down and almost trampled as all the civilians escaped the area. On stage QuirkThief and the one man from the GDF where fighting over the Revice Driver while Kirazaki watched Izuku from next to the stage before the two was knocked away where the T-Rex stamp landed near Izuku. Izuku spotted the stamp and grabbed it before the Deadmen could get it. The Ghost possessing him suddenly spoke up, "The Stamp! Use it on yourself!" Izuku was hesitant until he saw Uravity being held up by the Nomu by the throat. The Ghost shouts, "We can save everyone! You just have to let me out!" Izuku saw that Uravity was going to die if he did nothing. Izuka screams before using the stamp over his heart and out of his body without a contract being seen the Ghost appeared with legs and a tail. The Ghost spoke again, "It is good to stretch my legs!" and started laughing loudly before leaping at Nomu and punched Nomu's jaw off his body and knocking it away from Uravity. The Ghost looks to Uravity and says, "Oh you look tasty," Uravity blinks in fear only for the Ghost to offer a hand as he says, "Can't have you laying on the job.

Kirazaki blinks at this before he smiles as he sees the Revice Driver where he can grab it only to notice a Demon heading for Izuku, "Izuku!"

Izuku blinks before he noticed an elephant demon rushing to attack him only on instinct for Izuku to suddenly punch the demon and watched as it flew back at high speeds and into a wall at the other end of the gym.

Izuku was in shock as his ghost had noticed what happened to Izuku and rushed back over and say, "Careful with that strength of yours I am not in you stopping you from killing anyone at the moment."

Izuku blinks and before he could ask about it the pair side punched a second demon that arrived to attack them. They were in perfect synch as Kirazaki shouted again, "Izuku use this!" and slid the Revice Driver along the ground to Izuku and says, "Henshin!" and posed with his arms a very iconic pose to those watching.

Izuku was hesitant before his ghost says, "It has always been your dream! So let's do this! Don't you agree?" looking to the reader confusing Izuku.

Izuku shakes his head before placing the Driver on his waist creating a purple belt around his waist before the Ghost vanished back into his body. Izuku blew on the T-Rex stamp and quickly slammed it down on the white square he needed to stamp. Behind him a text chat screen was seen exchanging texts between Izuku and the Ghost as the Ghost appeared again still attached to Izuku holding a giant stamp. Izuku slots the stamp into the slot and shouts, "HENSHIN!" and turns the stamp pad revealing a mirrored image of the stamp he was using. –RE-RE-REVICE!- as the giant stamp stamped on him leaving Izuku inside the giant stamp with liquid that formed a blue and pink armour in the shape of a T-Rex. The ghost appeared again looking the same only now sporting some shin, forearm armour, a T-Rex helmet and scarf. The two shared having the stamp symbol on their chests after transforming.

Kirazaki shouts, "KAMEN RIDER REVICE!" with his arms in the air before Nomu charged Revice and his ghostly demon rushed over to destroy him only for Revice to catch his punch as it created a shockwave.

With that Revice and his Demon shot a double punch into Nomu's chest launching Nomu up before they both jumped upwards and kicked the Nomu through a wall. With that the Deadmen demons rushed forward and tackled Revice and his demon out the building and the two were forced to fight both demons and all of the Deadmen Minions.

Uravity and many of the other heroes were too exhausted to follow them though QuirkThief was hesitant while the Random GDF officer finally understood why Kirazaki did not want him to use the Driver, because he already found a user.

Revice was fighting the Deadman and managed to get one of the minions against a concrete wall before Revice punched the minions head and destroyed the concrete turning it into chunks. He then stomped on the ground causing the ground to shake from tremors before he fought a group of minions before a gorilla demon tackled him away.

Revice's demon was fighting the Deadmen as they struggled to overpower the demon. Revice's demon was clawing and kneeing the Deadmen until they were all down. He was then tackled by an Elephant Demon that Revice's Demon caught the two tusks and created two groves in the ground. Revice's Demon then goes on to say, "You give demons a bad name," before lifting the Elephant Demon over his head before flip slamming it to the ground behind him.

Karizaki then rushed out with a somewhat recovered Uravity holding another smaller stamp, "Hey Izuku! Use this," and throws the dark purple stamp to Revice before gesturing to him to stamp his hand.

Revice followed the Instructions and proceeded to watch as it formed an axe weapon that if turned turned it into a gun. Revice gave the axe a test swing before slashing at the Gorilla Demon he was fighting and managed to knock it away and into the Elephant Demon. Revice's Demon came over and says, "We should call that the AxeStamping Blaster. Right?" he turned to the reader.

"We need to end this," Revice states ignoring the apparent forth wall break.

"Right!" Revice's Demon shouted before leaping over the two demons slashing the Elephant a couple times. While Revice used his stamp on himself creating a pair of dinosaur legs and leaped at the two kicking them with high powered kicks. Revice replaced the Stamp in his Driver before being in the exact opposite side of the two demons and proceeded to shift the lever twice before Revice and his Demon had glowing right legs before they leaped high into the air and proceeded to complete a drop kick as a transparent stamp appeared on their right legs. The stamps crashed into the two demons and destroying them with an image of the T-Rex stamp as Revice's Demon shouting and posing as he says, "3! 2! 1!" before he roars as the two demons exploded.

Revice was calming down taking deep breaths as he thinks on what the hell was going on. Revice was looking over his arms and body as his Demon came over and hugged Revice in joy. Kirazaki came over clapping as he says, "Kamen Rider Revice!" gesturing to Izuku before pointing at Revice's Demon and says, "And you are Vice."

"Is that my name?" Vice questioned getting a nod from Kirazaki before Vice started whooping in joy.

Revice suddenly flipped the driver before removing the stamp as Vice vanished and Izuku replaced Revice before pushing the Revice Driver on Kirazaki and leaving quickly without a word. Surprising Kirazaki and Uravity at the situation. Though many GDF soldiers had seen the fight towards the end surprised with what happened and that Kirazaki's Revice Driver worked.

The three leaders of Deadmen had already called off the Nomu they borrowed for their announcement. The Green leader simply says, "It appears the enemies of Deadmen are ready for us," before the three vanish with energy much like their colour choices.

GDF Mobile Base/Head Quarters-High in the sky-Night

Inside one of the World's most secure locations, a flying fortress powered by an invention of Kirazaki so that it never had to land except for when they want to conceal loading of and unloading of cargo and supplies. Either way the Flying Might was a beast of a ship with many secret extras that the Heads of the GDF did not know of.

The main command room was a table along with a lounge for meetings and casual get togethers in a sense as emergency control took over the room would shift to what was considered a helm of a boat. Currently Kirazaki sat on the lounge while a man wearing a white trench coat, the captain of the GDF's base and the man selected to use the Revice Driver stood at a table facing a holographic screen were listening to an Audio only call from the Chairmen of the GDF, "We are not happy Kirazaki. Why did a civilian use GDF equipment? Also for that matter, why did one of the heroes on security think they were to get the Driver?"

Kirazaki sighs loudly before standing, he gets close to the Microphone of the call before speaking, "I TOLD YOU THE SPECIFICATIONS OF WHO CAN EVEN USE THIS VERSION OF THE RIDER TECHNOLOGY REQUIRED!"

The Chairmen were silent until the apparent head spoke again, "Which was disregarded as you had stated you required a Quirkless Rider. Sergeant Hiromi Kadota followed your requirements." Kadota was a stiff middle aged man with plenty of training and short brown hair.

Kirazaki growls and says, "His Quirk: Elf Ears, makes him not suitable," he was annoyed at everyone, "I needed the user to not have a Quirk, but also a high concentration of Gifu Antibodies. Izuku Midoryia, one of the few born Quirkless." Kadota was angry at this comment until Kirazaki spoke again, "I mean not even All For One's victim who lost their Quirk to him are acceptable. Any trace of originally having a Quirk will make the technology lethal to the user."

Everyone blinked at that before the Captain comments, "You were going to let us use it on him."

Kirazaki laughs before saying, "Of course not, why do you think I invited Izuku Midoriya and Vice?" he was being snarky, high and mighty as he laughed at them.

Sergeant Kadota asks, "According to everyone's reports at the end of the fight he returned the Driver and Stamps to you."

Kirazaki hums before admitting, "That was surprising, I reviewed his history, apparently he was known to desire being the next All Might. He is also still considered a big fan with his internet history. Though he is really innocent in that sense as all his Hero 'Research' was all just news related nothing about gossip or photo shoots. Though he was also part of the 'Noah' Group a while back. Meaning we have DNA samples on him, hence why I am surprised that no one who read my report stating that I named Izuku Midoriya as the only known candidate to use the Revice Driver at this time."

The Chairmen were silent as the Captain spoke up, "It appears that not every was willing to read the entire ten pages."

"It was eleven with a cover page that gave everyone a list of what I wanted and why in dot points before the actual report," Kirazaki growls out, "Why is it that I am the smartest person in the room yet I have the most common sense!?"

Everyone was silent about that before the Captain spoke again, "I will direct us to the fact at hand here then. Midoriya gave you back the Revice Driver."

Kirazaki nods in understanding before stating, "That I did not expect, but it may have something to do with the fact that the GDF banned those without Quirks being heroes."

The Captain sighs at this recurring argument as he says, "They make up less than one percent of the total population, and you already know how a person being born Quirkless these days, considering that they either die during birth or the mother miss carries."

Kirazaki rolls his eyes as he then says, "That is because of the Gifu Antibody side effect!"

The Captain then goes on to say, "That could kill them at any moment."

Kirazaki huffs before he says, "Hence why I chose Izuku," and walked away from his relaxation area to go to his Lab leaving the Revice Driver in a case on the table.

The Captain sighs and says, "I can never understand that man," before he noticed one of the Cadets that was at the GDF press conference, the one that Izuku waved to. The Captain spoke, "Cadet Daiji, you are friends with Izuku Midoriya?"

Daiji Akamaru, a last name he adopted after the Noah Incident. Daiji spoke, "Yes, we have been friends for years. Even worked with him at the Hoth Bathhouse for a time."

The Captain nods before commenting, "Then we have a task for you Agent Daiji Akamaru," Daiji blinked as he was given full membership to the GDF. "We need you to have Izuku Midoriya sign a contract with the GDF and for you to give him the Revice Driver once he signs."

Daiji blinks before commenting, "Um, that may be a problem. Izuku has a couple problems especially considering the Press Conference was broadcasted live and he was seen using the Revice Driver."

Hiromi Kodato asks, "How bad could that be?"

"His mother and a certain Hero constantly in the news being able to fight Nomus one on one," Daiji states causing the Captain and Kodato blinked and groans at that news. "Yes, KingExplosion knows where he lives and Revice's fight went viral."

The Captain nods before Kodato asks, "What about his mother?"

Hoth Bathhouse-that moment

Izuku struggled as he held onto a pillar as his body was perfectly horizontal as his mother, Inko Midoriya was pulling on the man with her Telekinetic Quirk to take Izuku home. Vice was commenting, "This takes helicopter parenting to a new level," and laughs.

With Daiji-That moment

"Yeah, I will speak to him first thing in the morning," Daiji states simply before being excused, leaving the case with the Captain and Sergeant.

With Kirazaki-later that night

He was programming several stamps on his computer. Unfortunately all of his work was delayed as all of the Stamps he developed had been stolen during a transport to an offsite facility. These stamps were designed so that as long as you were holding them they let you control the demon you summoned. It was so successful that even people with Quirks could use the stamps. Hence why they were stolen by the Deadmens as they were obviously was used during the attack.

In his lab was a sealed container holding the Gifu Stamp, a dangerous relic that could kill anyone stamped with it while creating a monster that could destroy everything that came up against it. It hadn't been used in over thirty years though, but it was the basis of all the current stamps and Kirazaki no longer needed it in a sense.

Kirazaki leaned back as he pulled out the newest stamp he created and pressed the button on top, -Eagle- was said from the stamp causing him to smile before leaning back and looking to the other glass cases in the room, a red driver with an LED screen on the front that caused his eyes to narrow before looking away. Another case had a green driver with what appeared to be a gun handle. The last glass case was blue with black bars on the front.

Kirazaki looked to the roof while saying, "World of Heroes?" and shakes his head in disappointment, before looking to a wall to the side covered in posters of heroes in special poses and sharing a single trait, they wore their own Drivers to transform into Kamen Riders. Kirazaki's computer screen had an image of Revice and Vice, having green and purple styled bird armour.
