Remnant, Vale
~KAMEN RIDE~
~DECADE~
Nathan transformed into Kamen Rider Dark Decade. He was ready to face the pack of Grimm called Beowolves. Since he did not want to be seen when fighting he devised a plan. Before he left the fitting room he drew out a card out of the metallic book from the left side of his Decadedriver. The card had a picture of Dark Decade with a fade effect. He then pulled the side handles of the driver again and he inserted the card. Just then the driver's monotone voice played.
~ATTACK RIDE~
Dark Decade then activates the card.
~INVISIBLE~
The the card was in effect and it made Dark Decade invisible. With the desired outcome he snuck his way outside of the fitting room and left the clothes shop.
He went back to the same place where the Beowolves were and lucky for him there were no signs of any civilians, he assumed they evacuated, were rescued, or probably worst.
Dark Decade grabbed his metallic book and reconfigures it into a sword.
While invisible, he quickly dashed towards one of the Beowolves and slashed them to pieces. He had to be careful not to have any rage or bloodlust since he knew that Grimms in general can sense negative emotions which can ruin his stealth approach.
"I have to keep my cool from now on in case I fight more of these." As Dark Decade kept killing the Beowolves one by one, some continued their rampage and attack. One of them spotted a mother and her son, so it began to leap towards them with the intention to kill. Lucky for them Dark Decade spotted this so he reconfigured his sword into a gun and started shooting at the attacking Grimm. The Grimm fell to the floor with bullet holes on its body, this gave the signal for the mother to run away with her child. They did not know where the shots came from but they did not care and continued running to safety.
Dark Decade kept swinging his sword to kill the pack but they were so many. "Tch, where's the police when you need them," he questioned himself. "Oh yeah, they're useless in these types of scenarios, *sigh* typical."
The pack of Beowolves were increasing in numbers, as Dark Decade kills one, more takes its place. This made him tired and annoyed so he thought of an idea.
Dark Decade checked his surroundings to see if there are any civilians left to which he found none. "Good, time to put plan B into action," Dark Decade said as he pulled two cards from his book-sword-gun thing. "Okay, I never saw Decade pull out cards from his Ridebooker in any other forms besides its book form but at least this works," said Dark Decade as he scans the cards. The cards he pulled out were a Kamen Rider card and an Attack Ride card. The Kamen Rider card had a portrait of a different Rider. Instead of Dark Decade's picture it was that of a golden Rider. It had a golden mask, blue lens for eyes, a huge horn on the forehead, and two huge side horns on both sides of the mask's jaw area. The portrait had a resemblance of a beetle and below the portrait is the name of the Rider, "Caucasus."
"Well would you look at that, not only I'm a villain Rider but even one of my cards is related to the other villain Riders," said Dark Decade nonchalantly. He was not surprised to see what card he had drawn because he was kind of expecting it. In one of the series he watched, "Kamen Rider Decade," the main character has the power to transform into other Riders from different seasons but only the main Riders of their respective series. Since Nathan is Dark Decade he was somewhat certain that the Riders he can transform to were the villain Riders of each series.
With that revelation Dark Decade started up the Decadedriver and inserted the "Caucasus" card and activates it.
~KAMEN RIDE~
~CAUCASUS~
This made Dark Decade transform into a new Rider. The helmet of the Rider was that of the card it represents. The torso had golden platings with golden shoulder pads except the right shoulder had huge golden rhinoceros beetle horns and the arms were black with metallic paddings for each segment of the arms. The rest of the lower half was black with metallic paddings on the outer side of both legs and knees. This new form was Kamen Rider Caucasus.
After transforming the invisibility effect was starting to wear off so he had to act fast. He then inserted the other card which has the picture of Caucasus' full body but with an after image effect.
~ATTACK RIDE~
~CLOCK UP~
This made the area around him slow down including all living things. which gave him enough time to catch his breath and to wipe out the pack of Beowolves.
Dark Decade now known as Caucasus started walking and calmly cuts every Beowolf in half. He has no problem of them struggling or dodging since Clock Up sends the user to a point where time is severely slowed down to a stop. In his perspective the Beowolves are in super slow motion, much slower than the bullet scene from the movie, The Matrix. This makes the Beowolves look like they are in a freeze frame.
After DDCaucasus cuts every Grimm in half the effects of the Clock Up card finally finished but not without DDCaucasus walking away from the scene.
~CLOCK OVER~
With that, all the pack of Beowolves were splitting in half all at once as if someone did an anime single sword slash which in reality no one did. After that whole fiasco DDCaucasus transformed back into Nathan and the cops arrived to the scene to which they found all the Grimms' bodies were in half and starting to fade away.
Nathan was sitting on a nearby bench to rest and saw the cops doing their investigation, "took you guys long enough." Satisfied with his break and he stood back up to continue his walk.
"Highly doubt any cameras are fast enough to record that," Nathan said with subtle confidence as he was referring to the quick carnage he had displayed.
"Now, time to find out what episode of RWBY am I in," as Nathan was walking he was trying to figure out exactly which part of RWBY he was in because he remembered that in the show the only time there was a Beowolf pack attack was in Ruby Rose's Red trailer which happened outside a forest near a cliffside and Nathan was nowhere near any forest nor a cliff for that matter.
"This is annoying, the gods could've at least tell me where I am now or what moment in the show I'm in." Nathan continued his complaints while walking. He had no problem of being a Kamen Rider but the fact he was told to judge and destroy Remnant without giving him proper information, is one of the pet peeves Nathan has. He hates being given general information without much details unless there was a reason, a valid reason.
He continued his walk until he stumbled upon a familiar looking book store. "'Tukson's Book Trade,' maybe I'll find some useful and less vague information in there." Nathan proceeds to walk into the building and was greeted by a tall well built man.
"Welcome to 'Tukson's Book Trade,' home to every book under the sun." said the man as he greets Nathan as a new customer. The man had black hair with sideburns, hazel eyes, pale skin and hairy muscular arms. He was wearing a burgundy and black collared shirt and dark colored pants and shoes. He looks like a normal human being but Nathan knew that he was something different.
In RWBY there were three species that lived within the world of Remnant. First which is obvious are humans. Then there are the faunus who look like humans but with some animal traits, some are subtle and some are obvious, one example is Sun Wukong and his monkey tail. Finally there the are creatures of Grimm, black bodied monster with bone armor and masks. It has different species and they can vary. It is said that they are the manifestation of darkness hence why they can sense negative emotions.
Nathan knew that man was a faunus but did not make any mention of it not because it was insensitive but because it was a waste of Nathan's time.
"Thank you and I'm guessing your Tukson," asked Nathan. "I just assumed since you're the only person I see in the counter of this book store."
The faunus, now named Tukson, smiled and answered Nathan's questioned. "Yes, your assumption is correct." He then continued, "so, what can I help you with?"
"Uhh, yeah I would like to buy some books about weapon making, dust, auras, and Remnant's history." After Nathan's question he followed it up with another. "Do you also know any where I could stay?"
Tukson gave Nathan a response, "sure thing kid let me just look for those books and as for the second question, I'm sorry there's none around these parts."
"Okay, thanks anyways," said Nathan. As Tukson was heading over to the bookshelves to search for Nathan's requested books, Nathan was already thinking of a plan since there were no hotels or any other places to stay. "Hmm so there isn't a single hotel, welp, there goes staying in for a night." He continued thinking until he thought of an idea but he was not sure if it could work.
"So these books you need, are they for any school projects," Tukson asked Nathan as he scans through the shelves.
"Yeah, you could say that," Nathan responded. "Well it's more of reviewing some things."
Tukson went back to the counter and showed Nathan some books he could use. "Art of Weaponry and Dust," "Auras Within Us," and "The Once Full World," these were the books that Tukson found. This of course made Nathan satisfied at what he got so he paid Tukson in exact.
"Thank you for purchasing please come again," as Tukson expresses his gratitude.
"No problem and thanks for the books and maybe I will visit again see you around Tukson." Nathan waves as he leaves the bookstore.
It was already evening and Nathan kept on walking while carrying his newly bought books. He found a nearby bench under a well lit lamp post. He set his books on the bench and began initiating his idea he had earlier.
"Alright lets see if I can create that veil myself." Nathan reached his hand out and tried to make a portal. He waited for a few minutes until nothing was happening. "Alright, pocket dimension is off the list of ideas," he said with a slight tone of defeat.
It was already getting dark so Nathan had no choice. "Time for plan B," he then laid down on the bench using his books as pillows. He saw the night sky which was decorated with shades of dark blue and light purple. Stars were scattered all over the sky dancing around as they twinkle. The center piece of the this beautiful sight was ironically the broken moon which held everything together. It was like Nathan was staring at a work of art created by a genius painter. He smiles at the sky and as he closed his eyes he was wondering what the future holds especially with this new power of his and the fact that the fate of the world is in his hands.
