Things were going haywire for Squad 8 as they were not just facing Infernals but facing Deadmans.
They heard of Deadmans, it was unclear on who they are but they stole some of Vulcan's tech and used it to bring out the inner demons of people. They were more dangerous than the White-Clad.
Even the White-Clad, Assault was having difficulties with the Mammoth Deadman, and the Rex Deadman he created. Assault tried to use the Revice Driver, he stole from Vulcan but couldn't use it as he couldn't control his demon leashed up.
For Shinra, everything just went out of control, knew he had to do something, he wanted to be a hero, it's the promise he made to his mother.
"So yeah, by the way…" The black demon, Shinra has been talking to and only seeing interrupted his thoughts. "Don't you think it's about time you made clear how you truly feel for yours truly?"
"Huh?" Shinra glares at the demon.
"Ruuuude!" The demon mockingly says. "We have to clarify what we have to say to each other already!"
"Again, what the hell are you?!"
"I thought you already figured it out, I'm the demon living inside of you." The demon introduced himself.
Shinra was taken aback, he didn't really believe he had one, people always called him a demon, but he thought they were just insults.
"How about it? Want to make a contract together?" The demon suggested.
"What do you mean by contract?" Shinra asked.
The demon just chuckled before saying, "Selling your soul to the devil of course!"
Shinra flinched from the demon's laughter, that was something he didn't want to do. Before he could say or do anything else he heard a loud scream. He looks to see Iris, being knocked down by the Mammoth Deadman.
He saw everyone from Squad 8 was busy dealing with a White-Clad or a Giff Junior.
"Sister!"
"There's a way to protect your fellow squad members." The demon told him.
"Spit it out then!"
"You saw it right? Stamp yourself with that Vistamp and I'll be able to leave your body! Then I can beat those guys up!" The demon explained.
"For real?! You're not lying are you?!" Shinra said to the demon.
"Of course not, don't let fear grasp your partner. Fail to move, and you'll regret it for the rest of your life," The demon told him.
Shinra gritted his teeth. "Damn it!" Shinra ran towards the Vistamp and grabbed it.
He then stamped himself, darkness came out of his body before a large contract form flew out of his chest. The contract crumbled before turning into the demon Shinra was talking to.
"WOOOOOOOO! I'm finally out!" The black demon cheered.
The Rex Deadman charged at the black demon and tried to attack him but the black demon dodge it and punched the Deadman away.
The black demon jumps up and gives a generated black and blue energy kick at the Mammoth Deadman sending the monster back.
"S-sugei…" Shinra was amazed by the black demon's strength.
The black demon looks at Iris.
"You look delicious~." The demon says in satisfaction.
Iris could only look up in horror when the black demon looked at her with hungry eyes.
"Don't!" Shinra ran towards to save Iris but was blocked by Giff Juniors.
"Shinra! Grab the Revice Driver to control your demon!" Vulcan suddenly told him.
"But isn't it busted or something?!"
"I think the Driver is meant for you! Now get it if you want to save the Sister!"
Shinra nodded and kicked through the Giff Juniors before grabbing a hold of the Revice Driver and placed it in front of his waist making a belt form around his waist.
Before the black and blue demon even touches Iris, he is sucked back into Shinra.
Shinra pressed the Vistamp, activating it.
REX!
A glass screen is materialized behind the user's back, displaying the user and the devil's inner dialogue like a chatbox.
Shinra then blew air into the Vistamp before he stamped onto the Ohinjector, the devil then appeared out of Shinra's body and began to fly around Shinra as the black demon carried a giant, glass-like projection of the Vistamp.
COME ON! R-R-R-REX! COME ON! R-R-R-REX! COME ON! R-R-R-REX!
"Just what the hell did you make, Vulcan?!" Shinra shouted, watching the demon shout with glee and excitement around him.
"Living up to my title, now shut up and henshin!" Vulcan shouted back.
Shinra did what he was instructed.
"Henshin!" Shinra inserted the Vistamp into the Vistamp Go Slot and pulled the lever.
BUDDY UP!
Filling the giant Vistamp projection with pink energy, while the chatbox is marked with a red seal from the Vistamp.
The devil then stamps the Vistamp projection onto Shinra, the pyrokinetic is then bathed in the Vistamp pink energy
OHING! SHONING! ROLLING! GOING!
Armor is then formed onto Shinra, while the seal from the chatbox launches armor parts at the devil, giving him armor pieces to slightly match with Shinra.
KAMEN RIDER! REVI! VICE! REVICE!
He wore a combination of pink, turquoise, and a purple bodysuit. On the top of his torso was armored along with his shoulder. The center of his body was the color of torques and had a purple 'V' under his biceps. On his left bicep was the seal of a t-rex. He had turquoise and pink padded armor on his upper and lower arms. His gloves' fingers were sharp like claws with four fingers being pink while the thumbs were torques. There was also pink and turquoise padded armor on both of the legs and boots with the bodysuit's legs were purple. He had a torques helmet that had a faceplate of a dinosaur, the bottom of his helmet was pink that cover his helmet's mandible, his mouthguard was nothing but sharp teeth that went all the way to the side of his lips, he had long red visor eyes that a sharp points, there was a pink 'V' on the helmet's frontal with small purple eyes between the 'V' and red visors, there was a splash of pink on the center forehead. This is Kamen Rider Revi.
His whole body was black that looked like a bodysuit that had pink and black armor added to his body. He wore a pink scarf around his neck, a silver belt with pink half-circles on the belt over his waist, and a pink t-rex emblem in a purple circle on the left side of his bicep. He had black and pink armor shields on his shoulders, black and pink shin guards on his lower legs and pink pads on both sides of his legs. He had pink bracers on the outside of his lower arms with hands that had black claws. He also had a black and pink tail. His head was covered by a large t-rex helmet with the mouth being open showing the demon's large blue eyes. His helmet was black with the center being pink, the mouth had a small pair of pink teeth on the top and bottom jaw. He is Kamen Rider Vice.
"Woah…" Revi looks at himself.
Everyone from Squad 8 looks at Revi with awe.
"Now you're both Kamen Revice!" Vulcan pointed at Shinra. "Kamen Rider Revi!" He then pointed at the demon. "Kamen Rider Vice!"
"Is he talking about me? Am I Vice?!" Vice asked Revi.
Revi just slapped his hand onto Vice's head.
"Shut up! We'll talk about you almost taking a bite of the Sister!" Revi told him before running to the monsters.
"Shinra-san, you know I was just joking, I wasn't going to eat your friend!" Vice exclaimed, before following Revi.
Revi charged towards the Rex Deadman giving it a power punch sending it to a wall making a few of the cement walls break off. Seeing a chance, Revi kicked the cement debris to a group of Giff Juniors destroying them.
"First thing first, we destroy these guys," Revi says.
"Alright!" Vice screech as he tackled three Giff Juniors.
Revi and Vice began fighting off the Giff Juniors.
"You're not half bad!" Vice commented.
The Mammoth Deadman came rushing into Revi as the pink Rider was fighting the Rex Deadman.
Vice kicked a Junior that was holding on to his leg. "Here I come!" Vice jumps towards the Deadmans and Giff Juniors Revi was fighting.
"How nice of you to help, for a demon!" Revi says.
"If you die here, then I'll die too, after all!" Vice replied.
"Wait what did you say?!" Revi was surprised by that sudden information.
"Shinra!" A voice called out to him.
"Huh, Vulcan?!"
"Use this!" Vulcan threw him a stamp. "Stamp this on your hand!"
"Eh?" Revi put the stamp on his hand.
The top piece of the began to form a weapon, an axe.
"Whoa! Vulcan really is the God of Smithing!" Revi was impressed by his new weapon.
"WOAH!"
Vice knocks a Junior away from him before running up to Revi.
"Let's call it OhinBuster since you used the stamp to bring it out!" Vice says.
Revi slashes a Junior before glaring at Vice, "That's not for you to decide!"
"It's fine, right everyone!" Vice looks at the Deadman and remaining Juniors.
"Let's just end this quickly!" Revi pulled the Ohinstamp off the axe's bottom hilt and blew on it before stamping it onto the Ohinjector.
STAMP-BY!
The blade of the Ohinbuster50 projects a larger cyan energy blade surrounded by red energy, which disappears before the physical blade itself is covered by blue energy.
OHING SLASH!
Revi then swings the weapon, launching three rotating pink energy seals of the Revice logo, with each seal surrounded by two light blue energy blades. The projectiles collide with the Giff Juniors, resulting in a large magenta explosion with a single large red and black seal of the Revice logo.
Now with the grunts out of the way, all that was left were the Deadmen. The Deadmen growled and charged at the Double Riders. Mammoth Deadman was dealing with Vice, while Revi dealt with the Rex Deadman.
"It's about time we both go all out!" Revi said.
"Now you're speaking my language!" Vice punched his fist to his hand.
Revi activates their finisher by pulling the Vistamp to the right side twice
The Rex Vistamp emblem on Vice's chest glows before producing magenta energy that travels down his body before covering his legs.
"Oh! What's this?!"
The Mammoth Deadman charged at Vice.
Meanwhile, Revi delivers a kick covered in pink and blue energy to the Rex Deadman before performing a second kick covered in the same energy that launches the Rex Deadman into the air. Vice grabs a Mammoth Deadman's arms and pulls them on top of himself before launching the Deadman into the air with a kick covered in pink and blue energy of his own.
Revi and Vice then jump into the air along with two large pink energy constructs of the Rex Vistamp.
REX STAMPING FINISH!
Each of them performs a flying kick into one of the Vistamp constructs and flies downward along with it, which produces a dome of pink and blue energy. The Vistamp constructs collide with both Deadmen and transform into large red seals of the Rex Vistamp emblem.
Both Revi and Vice each perform a second kick that creates another Rex Vistamp emblem and sends the monsters flying back toward the ground. Revi's kick creates a blue energy line while Vice's kick creates a pink energy line. The Deadmen fall along the energy lines and crash into the ground before exploding.
"Hehehe, nailed it!" Vice cheered.
AN: Why did I have Shinra became Revice, well mostly his smile, people calling him a demon or devil, I just thought I have to at least try this one-shot. I know FistOfKhonsu started a story with Revice & DxD, but I'm pretty sure written the scene or outfits yets maybe I the first.
Anyway, the first two episodes, I like it. I like the characters, I like the outfits, can't wait for other Riders and Revice future forms. Vice, there's a time where I get annoyed with his voice, but times he makes me laugh, so we'll see how it goes. Also, after two episodes we haven't gotten our Rider Machine, only a bike.
Sorry for taking a long time with chapters and stories but my laptop overheats and my keyboard gets too warm makes me want to stop typing. But I got three days off so I'm going to write as much I can. Till next time.
