This is a sorta reboot of 'A Rider in Remnant' as the original idea was too difficult to continue with the established number of Rider forms. In this story, he has only one Rider form but gradually gains up to three more different ones.

And since I now decide to pursuit this fic seriously, I have to consider the Color Naming Rule as well. My OC's name now is Zwart Parel, 'Black Pearl' in Dutch. He won't have a team as he is a Kamen Rider but he will still stay at Beacon due to plot reasons.

That's all I can say for now. Enjoy the story!

~Stage 1~

Rider Experience, an MMORPG that allowed people to become the iconic Kamen Riders and fight the monsters together. It functioned as a 'gacha game' as the first time you created your account, you would be asked to pull one ticket that would result in the Rider you become.

He was a college student like every other that had the required age to participate in this game. At first, he had entered this to kill his boredom and even though he had obtained 'Cronus', one of the most powerful Riders at that period and now, he neglected his avatar user and it took his friends quite an effort to convince him to rejoin the game as the current version was 3.6 and 1.7 was the last version he had logged in. He couldn't help it as he had his life to take care of.

[Welcome back, Zwart_Parel1209. This is the comeback reward as part of our Comeback Ceremony Event. Please receive it in the Mail section. Have fun!]

Navigating to the said area, there was an unfolded letter labeled 'Day 1 reward'. It was a weird multicolored medal, which he recalled never seeing before

"Must be a new item." Shrugging his shoulders, he put on the VR Googles and entered one of the daily quests. The destination was Fuyuki City, a location in Kamen Rider W. it usually required at least level 40 to enter but his was 45 so it should be sufficient.

[Connection established. Gachoon]

"Henshin."

[Buggle up! Ten wo Tsukame Kamen Rider. Kizame Chronicle. Ima koso Toki wa Kiwamaneri!]

The next thing he knew, that this was not a Rider Experience map at all.

"Mercury, Emerald, do it."

"Yes ma'am."

There was a trio circling around a girl with short brown hair. Despite her situation, the girl seemed confident. The only boy in the trio leaped at her with his leg, no, metallic leg, while the other girl with short mint-green hair brought her pair of sickles down. The cornered girl blasted them off with her wind and flame power but that only created an opening for the last one to strike her with her swords. It succeeded in bringing the girl to her knees and the two quickly apprehended her.

"Now, what am I going to do with you?" The woman asked out loud as she pulled out the glove on her right hand. There was a glowing crest on the forehand and she brought it closer to the girl. Tendrils spouted out from it and latched on her face and they began to drain something. The girl's expression went from shocked to weakened and was close to unconscious.

"Yo that's dirty."

Zwart thought this was a PvP match but he swore that he had entered an PvE area and PvP was impossible to initiate inside such areas. He pressed both red and blue buttons on the device at his waist.

[PAUSE]

A shockwave burst from his body to the surroundings. Immediately, everything around him froze in place. Cronus stepped out of his hiding spot and went to the crowd. He first kicked the man out and backslapped the green-haired to free the captive. When he tried to pull the tendrils out, he found that they were quite resistant to force.

"Tch. How troublesome."

[GASHOON]

Zwart took the Bugster Driver Zwei from the belt and attached it on the Grip Knuckle on his right hand and turned it around to extend the saw edge. Unsurprisingly, one slash from it and the stubborn tendrils were cut away. He then reattached it on the Buckle.

[GACHOON]

"And now, the finale. Hope you idiots learn the lesson not to pick on other players."

Cronus pressed the blue 'B' button twice as his visor flashed.

[KIMEWAZA! Rider, Critical Crews-Aid!]

A hologram of clockwork appeared beneath Cronus before he performed a reverse roundhouse kick on the woman with his feet growing with energy. The result was a frozen sphere energy on her body and the clock hands stopped at the XII. Once it's done, he pressed the two buttons on the Driver again.

[Shuuen no Ichigeki! RESTART!]

Time began to resume as the frozen midair duo flew away while the woman was blasted off by an explosion. The captured girl gasped for air as she looked around fanatically to find her attackers and found that they were scattered and injured, the woman earlier was in the worst shape. Anyone could tell that she was out of Aura and gravely wounded in the same time.

"What…the…?!" She looked up to see a weird guy in full-body costume staring down at her with his ridiculous helmet. But Amber could tell that he was the culprit. Both of them turned their heads toward the woman, who seemed to be groaning at the burnt marks and swollen spots on her body.

"Still alive? You must have a 'Continue' portion then. Well, I guess I have to delete your avatar again."

"What…the fuck…are you saying?!"

"Hmm?" Taking a closer look, Zwart realized that she was not in a Rider suit at all. In fact, everybody wasn't. "Seriously? Am I in a civilian location? What's wrong with this game?"

"Shut up! How dare you reduce me, Cinder Fall, to this state – Kuh!"

"Hmm, must be a bug." Cronus brought his hand to his chin and pondered. "Oh well, I will delete you for the admins then."

[GACHOON]

He let the Driver in Beam Gun mode and pointed it at the struggling woman as energy started concentrating in the muzzles. Before he could put this humanoid bug to oblivion, someone hit his back and this made his shot swayed to the other side.

"Hmm?"

"Em, grab Cinder and go! I will deal with this guy."

The gray haired teen was back and was yelling at his companion. Said girl nodded and supported the injured woman. Cronus slowly turned around as the boy kept hitting his back and it didn't hurt at all, aside denting his armor.

"Perhaps you first."

He pressed the trigger as the blast sent Mercury to the trees behind. Zwart flipped the device as the sawblade extended while approaching the man. The latter leaped for a divekick but Cronus easily intercepted it with his blade and grabbed the leg before crushing it.

"AAAAARGH! YOU ASSHOLE!"

"Tch tch, language language."

He pressed the 'A' button first and then 'B'

[KIMEWAZA! CRITICAL SACRIFICE!]

The blade glowed and extended with energy. Mercury could only raise his hands to defend as the attack came contact with him and swung him away. He landed near the female duo. The green-haired girl said something to him before taking out a circular object. She slammed it down on the ground and a thick smoke engulfed them. Cronus didn't bother to pursuit them as he knew this kind of tactic.

Returning to the girl, he opened his item case and chose the 'Heal' bottle before using it on her. The external wounds disappeared almost instantly as she examined her body in astonishment. She was about to stand up and thank him when what left of her strength went away and she collapsed.

"Hey!" Zwart was fast enough to catch her. Placing two fingers on her wrist to check her pulses, he was relieved to find them weak but still beating. He didn't know why he had done this on a virtual character but what's done was done. He bride-carried her and followed the wide path ahead before he felt someone was watching him. He stopped mid-track and turned his head to a big tree behind him.

"If you want another beating, feel free to come at me."

Qrow's heart skipped a beat. When the hell did that guy spot him so easily? Or was he just overcautious? He stayed at his position for a little longer until the guy in costume let Amber lie down and pulled out the strange device earlier onto his hand and aimed at Qrow's direction.

"Shit!"

The green-energy shot pulverized the branch Qrow was standing completely. The huntsman drew out his weapon and rushed at Cronus. His sword clashed against the sawblade and his instinct screamed at him to back away as the Rider grew his blade and it looked like the energy edge could cut through his Harbringer. He snapped the weapon to switch it to Shotgun mode and fired couple shots. Cronus withstood them and reattached the device back to the buckle before pressing both buttons.

[PAUSE]

[RESTART]

Qrow's back felt like it's going to break in half and his Aura was almost depleted. His face fell to the ground as his insides started to accumulate in his throat. A large shadow loomed over his sight with glowing lime-colored eyes staring down at him.

"Are you done? Now excuse me, I have a girl to tend with."

"What are you…gonna do…with Amber…?"

Cronus let out a questioning hum and looked at the unconscious girl.

"So her name is Amber. I happened to come across a three-on-one fight and decided to help the losing side. Are you her friend? I do recall not seeing you among the trio."

Qrow weakly grunted as acknowledgment. Cronus took out another Heal portion and threw it at the downed Huntsman. In seconds, all the wounds recovered. Qrow stared at him unbelievably.

"Just what's your intention?"

"Nothing." Cronus shrugged his shoulders. "It's just that you can do the job for me instead. You can call me Cronus. As much I want to talk more, I do have other businesses to attend so, see ya."

He walked away. Qrow wanted to say more but knew that it wouldn't gain nothing. He glanced at the sleeping Amber and shook his head.

"Man, what a good bodyguard I am." He took out his Scroll and dialed. "Oz, it's me Qrow…"

Zwart stopped walking in the middle of the jungle and thought of everything had happened. Cinder and Amber, these names sounded weird but for some reasons, he had a feeling that he knew them well. He tried to exit the area but was unable to as the interface hologram didn't show the 'Exit' option. Stranger, it only displayed three sections: Inventory, Battle Lessons and Map. The other seven were missing including the aforementioned Exit.

"This is getting creepier and creepier. Non-Rider PKers and characters from that one internet-show I have forgotten the name…"

He opened the Map. Wow, it even had the map of Vale stored inside the folders. He navigated the hologram and the closest location was the City of Vale, which was three kilometers from his position to the North. He was facing the East so Zwart made a turn and moved according to the instructions.

It didn't take long to get to the city. There was a security checkpoint in front of the entrance so he resorted to Pause to sneak past. Zwart didn't remember much about this animated show so the building layout confused him. The Map showed nothing except the path he had created.

'So I must obtain the map data then.'

He continued his way aimlessly. The bystanders stared at his appearance and took out their Scrolls to take pictures. Zwart didn't care as he probably wouldn't stay in this world until the server was fixed, he assumed. The NPCs could do anything they wanted.

Stopping in front of a bookstore, Zwart pushed the door slightly and entered. The owner, a beastman, was startled at his presence but he raised a finger and shh'ed.

"Just do whatever you are doing. I'm here to read some books."

"O-Okay then. Enjoy."

Zwart's hand trailed across the shelves to search for the map section. He found it and opened the first book, which was the overall map of Remnant. It further confirmed his theory that Rider Experience was having a collaboration event with RWBY, the name of this show.

'An almost-real simulation, huh…'

The helmet scanned through the book for a moment for any missing detail and Zwart changed to the others. In the span of five minutes, he had completed uploading the more detailed map of this world in general and this city specifically. He walked to the exit and thanked the owner.

'So, according to whatever left in my brain, I should be few months before the show even starts. The little girl in red will be in a Dust store while her sister will crash a bar.'

Zwart talked in his mind while walking, not knowing a shadowy figure tailing him.

'The time should move faster since this is a simulation after all. first, I need a place to rest. Should I get to the Club?'

Suddenly, he felt a sharp object hitting his nape rapidly. Turning around, he saw a dog-type beastman or Faunus as they were called in Remnant holding a knife. He was wearing some kind of uniform he couldn't remember seeing before. Zwart thought this guy was a White Fang.

"What can I do for you?"

"You are stepping into our territory, disgusting human."

"Oh, I do recall you animals have no right to call Vale 'your' territory."

Zwart had nothing about the race but having stabbed multiple times, him not feeling anything aside, and being called 'disgusting' were annoying. At the word 'animal', the Faunus roared and lunged at him. A simple jab sent him to the dumpsters.

"Pick someone in your level to bully, asshole."

The Faunus muttered something too small for him to hear but Zwart didn't care as he delivered one more kick at his face to silence him for real before leaving the area. All the scene was recorded by a CCTV nearby. Ozpin clenched his jaw after watching the short fight and looked at Scroll, thinking of Qrow's report. The man in full-body armor looked exactly the same with the description of Amber's rescuer and the drunkard's attacker.

'Is he an ally…or an enemy?'

Ozpin needed more time to monitor this mysterious 'Cronus' individual. He would have to connect to all of the CCTVs for this.

"Oh right, I have to get out of this thing." Zwart wondered out loud as he looked at his body. "Let's see. It should be like this…" He pressed the A button and then removed the Gashat from the Driver. The suit disappeared into data after that. He was in the default avatar outfit composed of a trench coat, a simple black t-shirt and brown pants. He took out the Gashacon Bugvisor Zwei and Buckle before putting them into his coat.

"Halt. Where is your ID boy?"

There were two guards outside the Junior's Club. One of them was blocking Zwart's way and demanded. He clicked his tongue as he hadn't even thought of this before.

"Well, um, my Scroll gets destroyed." Seeing the guard's more intense stare, Zwart spoke nervously. "A, and I'm here to apply for a job."

"Don't fuck with me, boy –"

"Wait, Jack." The other guard stopped his colleague and examined Zwart up to down. "You look tough enough. Actually, our boss is in need of a waiter. The last one was killed during a gang shootout. Let him in. If he's qualified, that's good. Otherwise, we will kick his ass."

"Hmm…" Jack frowned, eyes darting from his friend and Zwart. "You have a point. Stay put, I will go tell him."

A few minutes later, he returned. "Boss approved. Come in."

Zwart nodded and stepped into the building. True to its name, the club was very noisy and the music was starting to hurt his ear. He walked to the counter, where a middle-aged man in bartender outfit was waiting for him.

"So, you are our new waiter boy. Jack was right, you look tough enough. I may let you in but we will have to test you first. You alright with that kid?"

"No problem, Mr. Xiong."

"That's the spirit." Junior turned to the twin standing not far from the counter. "Melanie, show this new guy the thing."

The girl with long hair and white dress nodded and approached Zwart with a seductive hip motion. His left eye twitched.

"Hey cutie, what's your name."

"It's Zwart Parel, miss." He decided to use his username and gave her a polite bow. Melanie laughed at his attic and hugged his right arm with her left.

"Aw, don't be so formal. Just call me Melanie. Let's go, I will show you the 'stuff'."

Despite the suggestive word, Melania was showing him the worker's room and the waiter locker. She told him to change to the uniform and after that, he would be tested. Zwart complied.

'Wow, this is surprisingly comfortable to wear.'

He headed downstairs and Melanie was there to awe at his new appearance. Junior smirked and got his attention.

"Right, now. I need you to deliver these to table 6, 15 and 27. Do this flawlessly and I will let you in immediately. Got that?"

"Crystal, sir."

"Great. Now get to work."

Zwart picked up the tray with three glasses and went to the tables. He barely noticed the twin following him. He delivered the first one with no problem and now headed to table #15. As he suspected, Junior had told the girls to pester him. He paid them no mind as he continued his way with steady pace.

"Heeeey Zwartyyy, why are you ignoring us ladies~"

"Yeah~"

Zwart admitted; he had never encountered such twins like them. They almost got him but his previous experiences as part-timer of many jobs had taught him to keep his head cool.

"Please excuse me."

He said simply before placing the glass on the table. The guest grinned at him after realizing the situation.

"Junior's new guy, eh? An advice for you, kid: the previous guy was tricked into debts by Junior and his ladies so he had to hang himself."

"I…see. Have a good night."

"Watch yourself, kid."

He left the table and went to the last one. On his way, Zwart shot dirty looks at the twins, who flinched at his sudden change of attitude. They tried to make him talk but it was useless.

'Well, that's expected of them. After all, I'm dealing with gangsters here.'

The last guest was, he blamed his luck, Roman Torchwick.
